How to Sanitise your Eyewear
Including CLEAPSS guidelines…
Hygiene has always been an essential part of delivering practical science in educational settings. The unprecedented situation that teachers and technicians now find themselves in, means that these measures are more important than ever.
The current government guidelines will significantly limit the amount of practical activity that can take place whilst adhering to DfE guidance.

CLEAPSS guidelines state:
The guidance from the DfE requires that any equipment being transferred between bubbles is either cleaned ('meticulously') or quarantined for up to 72 hours.
"Resources that are shared between classes or bubbles, such as sports, art and science equipment should be cleaned frequently and meticulously and always between bubbles, or rotated to allow them to be left unused and out of reach for a period of 48 hours (72 hours for plastics) between use by different bubbles"
To increase the availability of equipment and efficiently utilise resources, it may be helpful to set aside time during the school day, when no new practical is planned and when 'meticulous' cleaning of key items, such as plastic eyewear can take place.
A specific room or prep room space could be set aside as a cleaning base.
Meticulous Cleaning
CLEAPSS believes that the following advice is sensible when trying to achieve meticulous cleaning.
'Meticulous cleaning' does not mean sterilise. CLEAPSS believes that careful and thorough cleaning that includes the use of an appropriate disinfectant is the intended meaning.
Cleaning plastic eyewear can be achieved with immersion in a solution of disinfectants, such as Milton or similar products, following the manufacturer's instructions.
Teens using chemistry set during high school science experiement
CLEAPSS TIP: Approx 15L of the solution is needed to immerse 30 safety glasses in a 24L stackable storage box with a lid.
For the disinfectant to work it needs to be in contact with the surface for the time specified on the product, typically between 10 and 20 minutes. This requirement can often be overlooked, and equipment not left for long enough.
CLEAPSS TIP: Keep immersion to the minimum specified time as some eye protection can deteriorate after repeated, prolonged immersion.
If eyewear has become dirty during a practical, they will need to be cleaned before they can be disinfected as surface dirt and grease will prevent the disinfectant from working. Plastic eyewear can be washed by hand in hot soapy water, then air-drying or drying with a soft cloth, which is then laundered.
Eye protection should be selected according to the degree of protection required.
Eye protectors are marked as follows:
Optical Class BS EN 166 Markings
Class 1 (High optical quality) 1
Class 2 (Medium optical quality) 2
Class 3 (Low optical quality) 3
Mechanical Strength BS EN 166 Markings
Increased robustness (12m/s) S
Low energy impact (45m/s) F
Medium energy impact (120m/s) B

text: Based on field data collected from 131 small scale dairy farmers that were randomly selected from four agro-ecological zones, this study assessed the potential of adoption of fodder bank technology as a means for improving livestock production and income generation for smallholder farmers in Zimbabwe. Using a logit modelling approach, it also identified the drivers of adoption of the technology by analysing the influence of household characteristics and ecological factors on farmersâ€™ decision to adopt the technology. The model correctly predicted 75% of observed adoption and non-adoption by farmers. Results reveal that dairy herd size, land holding size, membership of dairy association and agro-ecological potential are the key factors influencing farmersâ€™ adoption of fodder bank. Age, sex, household size and educational level of farmers play lesser role. Male and female farmers were equally likely to take up and practice fodder bank if they are given equal access to information and incentives. The study recommends farmer-led extension approaches where farmers who possess certain key characteristics should constitute the initial group for disseminating information regarding the technology in rural communities. The results highlight the importance of access to dairy product markets as a driver for the adoption of fodder banks. It is recommended that forging a strategic partnership with the Dairy Development Programme (DDP) will offer high potential for enhancing the scaling up of the adoption and impact of fodder bank technology in the country.

Sort your items using the Automatic Chest Sorter.
The Atlas chest sorting system works using storage minecarts and is able to move entire inventories instantly.
The storage cart can be put into one of three modes by having the cart pass over a powered activator rail with a wool block under it.
The color of the wool will change the mode of the minecart.
- Red Wool = Chest to Cart mode - Take items out of chests and put them into the minecart. (Note: currently to reduce abuse, the chest MUST be named "Input")
- Blue Wool = Cart to Chest mode - Take items out of the cart and put them into the chests.
- White Wool = Disabled mode - Returns the cart back to vanilla bahavior.
There are other settings that you can use:
- Green Wool = Leave one of each item type behind.
- Orange Wool = Don't leave any items behind.
- Yellow Wool = Leave one of each stack behind. (not implemented yet)
- Magenta Wool = Only transfer if the target already contains the same type of item.
- Brown Wool = Transfer regardless of what is in the target.
- Pink Wool = Top up existing stacks in the target. (not implemented yet)
Once you have configured the cart using the wool blocks, when the cart passes over a powered activator rail it will scan for nearby chests (2 blocks up, 2 blocks down, 1 block east, west, north, & south) and will put or take items as you have configured it.
Right click the minecart to view the current config.
It is possible (and recommened) to have a single cart in your base that performs all sorting activity,
== NEW FEATURES - NOT YET ON SERVER ==
Activator rail on Black Wool - Will search for a sign attached to the back wool block, and perform one of the following actions:
- "SetName" will rename the cart to the name specified on the second line of text on the sign.
Detector rail on Black Wool - Will search for a sign attacked to the wool block, and perform one of the following actions:
- "NameEquals" - Will activate if the carts name matches the one on the second line of the sign
- "NameContains" - Will activate if the carts name contains the text on the second line of the sign
- "NameStartsWith" - Will activate if the carts name starts with the text on the second line of the sign
- "NameEndsWith" - Will activate if the carts name ends with the text on the second line of the sign
- "CartType" - Will activate for the cart types on the second line of the sign: "Rideable", "Storage", "Explosive", "Hopper", "Spawner", "Powered"
- "HasPassenger" - Will activate if the cart has a passenger
Adding the word "not" to the thrid line on the sign will cause the output to be the opposite of what it would be normally.
Avoid having multiple signs near the wool block as it may get confused.
Activator rail on a hopper will cause minecarts to be 'killed' and deposited into the hopper.

Understanding Emotion Valence is a Joint Deep Learning Task
Gabriel Roccabruna | Seyed Mahed Mousavi | Giuseppe Riccardi
Proceedings of the 13th Workshop on Computational Approaches to Subjectivity, Sentiment, & Social Media Analysis
The valence analysis of speakers' utterances or written posts helps to understand the activation and variations of the emotional state throughout the conversation. More recently, the concept of Emotion Carriers (EC) has been introduced to explain the emotion felt by the speaker and its manifestations. In this work, we investigate the natural inter-dependency of valence and ECs via a multi-task learning approach. We experiment with Pre-trained Language Models (PLM) for single-task, two-step, and joint settings for the valence and EC prediction tasks. We compare and evaluate the performance of generative (GPT-2) and discriminative (BERT) architectures in each setting. We observed that providing the ground truth label of one task improves the prediction performance of the models in the other task. We further observed that the discriminative model achieves the best trade-off of valence and EC prediction tasks in the joint prediction setting. As a result, we attain a single model that performs both tasks, thus, saving computation resources at training and inference times.

Response Generation in Longitudinal Dialogues: Which Knowledge Representation Helps?
Seyed Mahed Mousavi | Simone Caldarella | Giuseppe Riccardi
Proceedings of the 5th Workshop on NLP for Conversational AI (NLP4ConvAI 2023)
Longitudinal Dialogues (LD) are the most challenging type of conversation for human-machine dialogue systems. LDs include the recollections of events, personal thoughts, and emotions specific to each individual in a sparse sequence of dialogue sessions. Dialogue systems designed for LDs should uniquely interact with the users over multiple sessions and long periods of time (e.g. weeks), and engage them in personal dialogues to elaborate on their feelings, thoughts, and real-life events. In this paper, we study the task of response generation in LDs. We evaluate whether general-purpose Pre-trained Language Models (PLM) are appropriate for this purpose. We fine-tune two PLMs, GePpeTto (GPT-2) and iT5, using a dataset of LDs. We experiment with different representations of the personal knowledge extracted from LDs for grounded response generation, including the graph representation of the mentioned events and participants. We evaluate the performance of the models via automatic metrics and the contribution of the knowledge via the Integrated Gradients technique. We categorize the natural language generation errors via human evaluations of contextualization, appropriateness and engagement of the user.

What's New? Identifying the Unfolding of New Events in a Narrative
Seyed Mahed Mousavi | Shohei Tanaka | Gabriel Roccabruna | Koichiro Yoshino | Satoshi Nakamura | Giuseppe Riccardi
Proceedings of the The 5th Workshop on Narrative Understanding
Narratives include a rich source of events unfolding over time and context. Automatic understanding of these events provides a summarised comprehension of the narrative for further computation (such as reasoning). In this paper, we study the Information Status (IS) of the events and propose a novel challenging task: the automatic identification of new events in a narrative. We define an event as a triplet of subject, predicate, and object. The event is categorized as new with respect to the discourse context and whether it can be inferred through commonsense reasoning. We annotated a publicly available corpus of narratives with the new events at sentence level using human annotators. We present the annotation protocol and study the quality of the annotation and the difficulty of the task. We publish the annotated dataset, annotation materials, and machine learning baseline models for the task of new event extraction for narrative understanding.

Evaluation of Response Generation Models: Shouldn't It Be Shareable and Replicable?
Seyed Mahed Mousavi | Gabriel Roccabruna | Michela Lorandi | Simone Caldarella | Giuseppe Riccardi
Proceedings of the 2nd Workshop on Natural Language Generation, Evaluation, and Metrics (GEM)
Human Evaluation (HE) of automatically generated responses is necessary for the advancement of human-machine dialogue research. Current automatic evaluation measures are poor surrogates, at best. There are no agreed-upon HE protocols and it is difficult to develop them. As a result, researchers either perform non-replicable, non-transparent and inconsistent procedures or, worse, limit themselves to automated metrics. We propose to standardize the human evaluation of response generation models by publicly sharing a detailed protocol. The proposal includes the task design, annotators recruitment, task execution, and annotation reporting. Such protocol and process can be used as-is, as-a-whole, in-part, or modified and extended by the research community. We validate the protocol by evaluating two conversationally fine-tuned state-of-the-art models (GPT-2 and T5) for the complex task of personalized response generation. We invite the community to use this protocol - or its future community amended versions - as a transparent, replicable, and comparable approach to HE of generated responses.

Can Emotion Carriers Explain Automatic Sentiment Prediction? A Study on Personal Narratives
Seyed Mahed Mousavi | Gabriel Roccabruna | Aniruddha Tammewar | Steve Azzolin | Giuseppe Riccardi
Proceedings of the 12th Workshop on Computational Approaches to Subjectivity, Sentiment & Social Media Analysis
Deep Neural Networks (DNN) models have achieved acceptable performance in sentiment prediction of written text. However, the output of these machine learning (ML) models cannot be natively interpreted. In this paper, we study how the sentiment polarity predictions by DNNs can be explained and compare them to humans' explanations. We crowdsource a corpus of Personal Narratives and ask human judges to annotate them with polarity and select the corresponding token chunks - the Emotion Carriers (EC) - that convey narrators' emotions in the text. The interpretations of ML neural models are carried out through Integrated Gradients method and we compare them with human annotators' interpretations. The results of our comparative analysis indicate that while the ML model mostly focuses on the explicit appearance of emotions-laden words (e.g. happy, frustrated), the human annotator predominantly focuses the attention on the manifestation of emotions through ECs that denote events, persons, and objects which activate narrator's emotional state.

Would you like to tell me more? Generating a corpus of psychotherapy dialogues
Seyed Mahed Mousavi | Alessandra Cervone | Morena Danieli | Giuseppe Riccardi
Proceedings of the Second Workshop on Natural Language Processing for Medical Conversations
The acquisition of a dialogue corpus is a key step in the process of training a dialogue model. In this context, corpora acquisitions have been designed either for open-domain information retrieval or slot-filling (e.g. restaurant booking) tasks. However, there has been scarce research in the problem of collecting personal conversations with users over a long period of time. In this paper we focus on the types of dialogues that are required for mental health applications. One of these types is the follow-up dialogue that a psychotherapist would initiate in reviewing the progress of a Cognitive Behavioral Therapy (CBT) intervention. The elicitation of the dialogues is achieved through textual stimuli presented to dialogue writers. We propose an automatic algorithm that generates textual stimuli from personal narratives collected during psychotherapy interventions. The automatically generated stimuli are presented as a seed to dialogue writers following principled guidelines. We analyze the linguistic quality of the collected corpus and compare the performances of psychotherapists and non-expert dialogue writers. Moreover, we report the human evaluation of a corpus-based response-selection model.

If any parts cannot be centred on the lathe for various reasons (hole through spindle too small, part too heavy, etc.), the centre square, centre bell or height gauge may be used depending on the specific application.
The part is machined on the end face which should be as plane and as flat as possible to avoid canting of the tools.
- Centring with the centre square
Fig. 20 shows how this is done:
The centre square is to be located at the workpiece diameter and a scribed marking of crossing lines to be applied by means of the scriber.

- Centring with the centre bell
When using the centre bell, scribing is not necessary. The centre of the workpiece is defined by the central position of the centre punch.
The centre bell is to be attached and applied as per Fig. 18 in section 3. It is held by one hand while punching is done with the other hand.
The diameter of the workpiece must be smaller than the diameter of the bell; otherwise the central position cannot be clearly defined. The centre bell must not be canted; otherwise the centre will be misplaced.

How do I determine transfection efficiency using a flow cytometer?
Posted February 19, 2020
Using flow cytometry, determining the success of a particular transfection procedure is quite simple:
- Use an untransfected control and subtract the baseline intensity data from your experimental results
- Signal intensity graphs are a simple visual aid to compare the response of the cell line to different transfection reagents
Manual analysis is likely unnecessary; most instruments have software with FACS analysis programs for quick results.

Double Red Donations
Red blood cells, which carry oxygen to all parts of the body, comprise 40-50 percent of blood volume and are the most commonly transfused blood product. They are used to treat anemia, for surgical operations and to replace blood lost due to trauma resulting from accidents or injuries.
A double red cell donation is an automated process that allows the donor to give two units of red blood cells in one visit. In this two-step process, two units of red cells are collected from the donor and other blood components like plasma are returned to the donor. A double red cell donation takes 30 to 40 minutes; the entire visit takes about an hour and 15 minutes, a bit longer than a whole blood donation.
Double Impact
As a double red cell donor you double your impact by providing twice as many red cells for patients in need. You also receive a $10 gift card as a thank you for your time and donation.
Donor requirements for double red cell donations:
 - Donors must be at least 17 years of age.
 - Donors must have an adequate blood iron level.
 - Female donors must be at least 5'5" tall and weigh 150 pounds.
 - Male donors must be at least 5'1" and weigh 130 pounds.
 - Donors must have an appointment to make a double red donation.
Type O donors are especially suited for double red cell donations because 45 percent of the population has Type O blood. Additionally, Type O Negative is in even greater demand because all patients can receive that blood type.
A donor can give double red cells every 112 days.

'N Sync hasn't recorded Chattanooga Choo-Choo, so the kids won't know the words. But for parents, it's impossible to drive into town without humming "Pardon me, boys…"
Yes, it's Chattanooga, home of the Choo-Choo. The train is part of the history and one of the city's attractions, but even without it, Chattanooga is a family playground. Attractions in town are within walking distance of each other or are linked by the free trolley. Outlying ones are clustered nearby. That limits choruses of "Are we there yet?" and most of the sightseeing is done while everyone still has energy.
The Tennessee River flows through the city. Much of the riverfront is open space and a riverwalk that takes advantage of the steeply rising bluffs. The Tennessee Aquarium sits on the riverbank. Devoted to freshwater ecology, it lets visitors vicariously experience the life of the creatures that swim just outside the building. Visitors walk 'through' the aquarium via an enclosed winding ramp with plenty of chances to get nose-to-gill through the glass.
Just a short stroll up the street is the Creative Discovery Museum. The discoveries start in the plaza outside the main entrance. Look closely, and you'll notice that the sculpture of carefree children playing in the sunlight is actually a sundial.
The museum's philosophy is 'learning is child's play,' but kids can get frustrated here. Not because the museum isn't fun, but because their parents are joining in – scrounging for dinosaur bones in one display and experimenting with optical illusions in another. The music studio, something not found in many kid-oriented science centers, has a great exhibit. The Shaker hymn "Simple Gifts" is heard in its traditional form, but also as a jazz piece, blues, rock, reggae, classical, and other musical styles.
The International Towing and Recovery Museum is the only museum in the world dedicated to tow trucks. Its collection of antique 'wreckers,' as the purists call them, is housed – appropriately enough – in an old car dealership. The old workhorses are enjoying a papered retirement; they're as painted and polished as the Model Ts, Studebakers, and other passenger cars they hauled from ditches and muddy ruts.
Walnut Street Bridge links the north and south banks of the river. At 2370-feet long, it's the longest pedestrian walkway in the world. Originally built in 1891, it was the only way to cross the river for thirty years. In the early 90s, engineers discovered it was structurally unsafe and closed it.
Rather than see it demolished, residents raised funds to repair and reopen it for foot traffic. Now, bikers, strollers, joggers, and dog-owners peddle, amble, trot, and walk across the river, surrounded by the ornate ironwork of the old bridge.
At the north end of the bridge is Coolidge Park. Named after Charles Coolidge, a Chattanooga resident who received the Medal of Honor, the park features interactive play fountains with squirting animals, an open lawn, and plenty of room for picnics. The main entrance, Medal of Honor Plaza, recognizes all recipients of the nation's highest military honor.
The park's main attraction is the Chattanooga Carousel. Rescued from decay in Atlanta, it's been restored and fitted with 52 hand-carved animals. In addition to horses, the menagerie includes leaping tigers, well-dressed frogs, and friendly dinosaurs.
All of the carousel animals were carved at Horsin' Around, the country's only school where the vanishing art of carving carousel horses is taught. It's a place of sawdust and smiling rabbits, half-assembled elephants and paint samples, the smell of fresh-cut wood and the sound of an old barrel organ.
Horsin' Around is at the foot of Lookout Mountain, just outside the main part of town. Three of Chattanooga's oldest and most famous attractions are on top or inside.
The most interesting way to reach the summit is via the Incline Railway. The steepest railway in the world has passengers looking nearly straight down between their feet as the car hauls itself up the mile of track.
The panoramic view from up top is a definite Kodak Moment, but it's just as impressive inside the mountain. Viewing Ruby Falls means following a guide through caverns to a 145-foot waterfall deep inside the mountain. The falls were discovered by accident by workers who were engineering an elevator shaft in the caverns they already knew existed. They splash into a deep pool while colored lights play on the spraying water.
This is a good spot for lunch or a snack break. The garret of the visitors center, located in a stone building designed to resemble 15th century Irish castle, offers more fantastic views of the Tennessee Valley and a large play area for kids.
"See Rock City." If there was ever a catch phrase for travel in the south, that's it! For decades, the black-and-white admonition adorned barn roofs from Louisville to Asheville.
The original American tourist attraction started in the Depression years. Plans to create a mountaintop resort were derailed by the economic crisis, so Garnet Carter and his wife, Frieda, shifted their energies to Frieda's dream of turning the precipice into an elaborate rock garden.
She laid out winding paths through the rock formations and planted hundreds of wildflowers and shrubs. A lover of German folklore, she imported statues of gnomes and fairytale characters and put them along the path, too. Many of them ended up inside the mountain, where underground grottos hold scenes from fairy tales to catch the imagination of children and their parents.
The rocky, jutting crag of the mountain promises a vista of seven states. Really? Current owner Bill Chapin, Garnet and Frieda's grandson, grins with the impishness of one of the gnomes. "Depends on the weather and whether or not you want to see them all."
No gnomes hid on Lookout Mountain in 1863, when Confederate and Yankee Troops fought for control of Chattanooga and the Tennessee River. The fog on the mountain and the smoke from the battle were so thick that the fight became known as The Battle Above the Clouds. That campaign routed the Confederates from the area and set the stage for Sherman's advance on Atlanta.
The Battle of Chattanooga Electric Map and Museum explains the battles with a three-dimensional lighted diorama that uses 5,000 miniature soldiers, plus lighting and sound effects. It's at the edge of Lookout Mountain, as the entrance to Point Park, where Confederate and later, Yankee, troops watched the city.
Surrounded as it is by the Tennessee River and the mountains, Chattanooga naturally offers lots of family outdoor activities. The adventures can be as mild as a 90-minute cruise on the Southern Belle. The sternwheeler paddleboat has a schedule of lunch and dinner cruises from April through October, with a limited schedule during the winter months. Family Night serves up prime rib for the parents and spaghetti for the kids. The daily lunch cruise has a "Build-Your-Own" sandwich buffet.
Back on shore, Suck Creek Cycle rents bikes, arranges and leads tours, and dispenses advice for bikers and tourists in the heart of town. It's adjacent to the Aquarium and convenient to the Walnut Street Bridge.
Hundreds of miles of hiking trails meander their way through the mountains surrounding the city. Point Park, atop Lookout Mountain, has 25 miles of trails. That's the closest hiking area to the city center. As the name hints, Fall Creek Falls State Park, has numerous waterfalls, including the 256-footer that gives the park its name. Prentice Cooper State Forest and South Cumberland State Recreational Area also boast over 13 miles of trails each.
No one's exactly sure when the doors first opened, but the Mountain Opry may have started about the time the Sherman left for his march to the sea. Tucked away on the backside of Signal Mountain, it's a regular Friday night gathering of local pickers, fiddlers, and singers performing authentic bluegrass and mountain music. Refreshments are hot dogs and popcorn; seats were rummaged from old movie houses and churches; the audience knows most each other and greet visitors like family. Admission is free, with a hat passed around on occasion to cover the costs of keeping the lights turned on.
And while they play a lot of mountain standards, no one recalls if any of the pickers every played a bluegrass version of "Chattanooga Choo-Choo."

Machine learning has revealed exactly how much of a Shakespeare play was written by someone else
Literary analysts have long noticed the hand of another author in Shakespeare's Henry VIII. Now a neural network has identified the specific scenes in question—and who actually wrote them.
Photograph of Shakespeare manuscriptPhotograph of Shakespeare manuscript
Photograph of Shakespeare manuscriptAP
For much of his life, William Shakespeare was the house playwright for an acting company called the King's Men that performed his plays on the banks of the River Thames in London. When Shakespeare died in 1616, the company needed a replacement and turned to one of the most prolific and famous playwrights of the time, a man named John Fletcher.
Fletcher's fame has since quelled. But in 1850, a literary analyst named James Spedding noticed a remarkable similarity between Fletcher's plays and passages in Shakespeare's Henry VIII. Spedding concluded that Fletcher and Shakespeare must have collaborated on the play.
The evidence comes from studies of each author's linguistic idiosyncrasies and how they crop up in Henry VIII. For example, Fletcher often writes ye instead of you, and 'em instead of them. He also tended to add the word sir or still or next to a standard pentameter line to create an extra sixth syllable.
These characteristics allowed Spedding and other analysts to suggest that Fletcher must have been involved. But exactly how the play was divided is highly disputed. And other critics have suggested that another English dramatist, Philip Massinger, was actually Shakespeare's coauthor.
Which is why analysts and historians would dearly love to determine, once and for all, who wrote which parts of Henry VIII.
Enter Petr Plecháč at the Czech Academy of Sciences in Prague, who says he has solved the problem using machine learning to identify the authorship of more or less every line of the play. "Our results highly support the canonical division of the play between William Shakespeare and John Fletcher proposed by James Spedding," says Plecháč.
The new approach is straightforward in principle. Machine-learning algorithms have been used for some years to identify distinctive patterns in the way authors write.
The technique uses a body of the author's work to train the algorithm and a different, smaller body of work to test it on. However, because an author's literary style can change throughout his or her lifetime, it is important to ensure that all works have the same style.
Henry VIII authorship
Once the algorithm has learned the style in terms of the most commonly used words and rhythmic patterns, it is able to recognize it in texts it has never seen.
Plecháč follows exactly this technique. He first trains the algorithm to recognize Shakespeare's style using other plays written at the same time as Henry VIII. These plays are The Tragedy of Coriolanus, The Tragedy of Cymbeline, The Winter's Tale, and The Tempest.
He then trains the algorithm to recognize the work of John Fletcher using plays he wrote at this time—Valentinian, Monsieur Thomas, The Woman's Prize, and Bonduca.
Finally, he lets the algorithm loose on Henry VIII and asks it to determine the author of the text, using a rolling window technique to scroll through the play.
The results are interesting. They tend to agree with Spedding's analysis that Fletcher wrote scenes amounting to almost half the play. However, the algorithm allows a more fine-grained approach that reveals how the authorship sometimes changes not just for new scenes, but also towards the end of previous ones. For example, in Act 3, Scene 2, the model suggests a mixed authorship after line 2081 and finds that Shakespeare takes over completely at line 2200, before the start of Act 4, Scene 1.
Plecháč also trained his model to recognize the work of Philip Massinger but finds little evidence of his involvement. "The participation of Philip Massinger is rather unlikely," he concludes.
That's interesting work that shows how linguists and literary analysts are using machine learning to better understand our literary past.
However, there is much work ahead. For example, when machine vision algorithms were trained to recognize artistic style, computer scientists quickly worked out how to extract a style and apply it to other images, using a technique known as neural style transfer. Overnight, it became possible to give an ordinary photograph the style of a Van Gogh or a Monet.
That raises the question of whether a similar technique is possible for text. Might it be possible to transform an essay, or indeed an article for MIT Technology Review, into the style of Shakespeare or John Fletcher, for example?
Sadly, not yet, other than in the trivial way of replacing word like them with 'em and so on. This is largely because the underlying structure of communication is not well enough understood by linguists or their algorithmic charges.

Opisthobranch of the Week Data
Phyllidiopsis krempfi is considered to be rare on Okinawa as I have collected only four individuals as of mid August, 2000. Although I'm suggesting the species is rare here, I suspect that I've seen others, erroneously assuming they were of more common species. There are several reasons for this, but perhaps the best reason is that many Okinawan phyllidiids are very commonly seen here and I've tended in the past not to pay much attention to the group.
The closest appearing Phyllidiopsis species on Okinawa is P. pipeki, with similar mantle and rhinophore coloration, but Brunckhorst (1993) points out that P. krempfi is very tuberculate with many multicompound tubercles, whereas P. pipeki has sparsely scattered single and compound tubercles. Also, an apparently consistent feature seen in P. krempfi is the presence of the two black primary longitudinal lines which extend around the rhinophores and join at a point anterior to the rhinophores.
I have a second page showing two separate images of an additional 50mm animal collected from 69m. The second of these two images show the animal feeding on a thin brown sponge (the small brown sponge was growing on the surface of the larger yellow sponge). This phyllidiid stayed on the sponge following its collection, transport, and subsequent photography hours later; I can only assume that it was more than just a bit hungry.
As of mid-July, 2007, the following eight described species of Phyllidiopsis have been featured on the Okinawa Slug Site:

Over the past few years, wireless sensor networks received tremendous attention for monitoring physical phenomena, such as the temperature field in a given region. Applying conventional kernel regression methods for functional learning such as support vector machines is inappropriate for sensor networks, since the order of the resulting model and its computational complexity scales badly with the number of available sensors, which tends to be large. In order to circumvent this drawback, we propose in this paper a reduced-order model approach. To this end, we take advantage of recent developments in sparse representation literature, and show the natural link between reducing the model order and the topology of the deployed sensors. To learn this model, we derive a gradient descent scheme and show its efficiency for wireless sensor networks. We illustrate the proposed approach through simulations involving the estimation of a spatial temperature distribution.

OverviewAs part of a technology upgrade for an application, I recently rewrote a collection of Python classes to use xml.etree instead of xml.dom. The application used pretty much all of the libraries: reading in xml strings to create in-memory representations, then searching them for various values. Taking a non-xml data structure and creating an xml representation of that, then writing it out in a string for future use.
Before starting, I went looking for a document discussing this kind of rewrite, in hopes of avoiding any gotchas that might be lurking in the process. I was a bit surprised to find - well, not find - such a document. Either this process isn't all that common, or there aren't any gotchas. In either case, it's complicated enough that I think it's worth discussing the differences.
Converting code from using the DOM to using an ElementTree API is relatively straightforward. I'm going to cover the major details, pointing out any gotchas I've found. However, this is not a guide to either ElementTree or the DOM. It should be sufficient for most such conversions, but you may well be able to improve a specific bit of code if you study the ElementTree documentation.
The ElementTree API was designed for Python, so you are unlikely to find it elsewhere. Objects provide standard Python API's to access related parts of the DOM, rather than having methods and/or attributes from the DOM spec for that.
There are mutiple implementations of the API. Recent cPython versions ship with ElementTree and cElementTree. lxml provides an ElementTree implementation based on the libxml C library, and thus includes both fast XML processing and features that aren't available in the included versions.
Extracting dataData in an XML tree comes in three forms:
- Element nodes, which hold everyting.
- Text in a node.
Attributes are easy. Instead of
getAttribute, you have
getAttributeNode(and similar) don't exist in ElementTree. The attributes in ElementTree look like dictionary items on the node - except for lack of
__getitem__and the ability to iterate over them (which means that
indoesn't work on them!). If you really want a dict, you can get it from the nodes
The gotcha here is that
getAttributereturns an empty string if the attribute doesn't exist.
getis the standard dictionary function, and has a second argument (which defaults to
None) that is returned if the attribute isn't there. So watch for
hasAttributetests used to deal with the default value in some way, and rewrite them as appropriate.
TextText is where things start getting strange. Text in the DOM is stored in a
TextNodenode type. In ElementTree, text is stored in the nodes
tailattributes. To find all the text in a DOM node, you iterate over the children of the node looking for TextNodes, and get the text from their
In ElementTree, the
textattribute holds any text that immediately follows the tag opening. The
tailattribute holds any text that immediately follows the tag closeing. So the equivalent process is to get the nodes
textvalue, then walk the child nodes, collecting their
In well-designed schemas (which don't have what is known as mixed content, with both text and nodes as children), both processes are much easier. The DOM pattern is to get the first child, make sure it's a text node, and then use it's
dataattribute. In ElementTree, you can just use the
ElementsThe easy part is the name of the tag: it's
namein the DOM (depending on exactly what you want) and
tagin ElementTree. However, there is a major gotcha in dealing with elements at all. A DOM node is always true. An ElementTree element is false if it has no children. Even if it has attributes or text, it will be false if there are no children. This is standard Python behavior for lists. It means that tests like
if node:need to be rewritten as
if node is not None:. On the other hand, testing for no children is simpler. The DOM has a
childNodesattribute to provide a list of child nodes - including text nodes. With ElementTree, the node itself provides the Python list interface to the children.
More importantly, the only way to search for nodes in the DOM is via
getElementsByTagnameNSmethods. These walk the entire subtree of the node, looking for that name.
ElementTree provides the
getIteratormethod that does pretty much what the DOM methods do. It is somewhat more powerfull, in that it accepts limited XPath expressions as well as simple tag names. How limited the XPath expressions are depends on the implementation, but intelligent use of these can move some checks into a C code library to improve performance.
There are two gotchas with
getIterater. The first is that it can return an iterator instead of an iterable (up to the implementation), so you may need to pass it to
listto get an iterable, depending on what's done with it and whether you want to maintain portability across ElementTree implementations. The second is that, unlike the DOM methods, it includes the current element in the search. So you need to insure that the current element doesn't match the search expression.
However, if you know something about the schema, you may be able to improve performance here. ElementTree nodes have
findAllmethods that return the first node matching the search, or an iterable over all such children, respectively. Matching is the same as for
getIterator. So, if you know that you're looking for a child node, these can be used instead of
getIteratorto save searching grandchildren, etc.
Odds 'n EndsA few random things that don't fit in the above.
Adding NodesIn the DOM, you add a node by using an appropriate
create*Foo*method from the
Documentobject it's going to be added to, then add it where you want it. For ElementTree, you should usually use the the
SubElementfunction. That will create the appropriate element and append it to the nodes children.

Word into art
Word into Art
This tour brings together the work of contemporary artists from the Middle East and North Africa. The use of writing - quotations, words and even single letters - has emerged as a common theme in this vibrant and original art. Each object presented here is inscribed in or draws its inspiration from Arabic, the main script of the region used to write a variety of languages including Persian.
A Sacred Script looks at artworks which are based around the holy texts of the Qu'ran and the Bible. Literature and Art shows how poetry and the rich literary traditions of the Middle East have inspired artists in different ways. The works in Deconstructing the Word have been created using single words or letters. History, Politics and Identity examines how art has responded to crises and wars that have affected the Middle East. In the entry for each work, the artist's country of origin is cited first after their name, and their current place of residence second.
The tour includes highlights from Word into Art: Artists of the Modern Middle East, a free exhibition at the British Museum (Room 35) from 18 May to 3 September 2006. The exhibition draws mainly on works collected by the British Museum, with some loaned objects. It includes pieces by about eighty different artists, some of whom are represented here. This tour shows how writing, so important as both a method of communication and an art form in the ancient and Islamic cultures, continues as a powerful thread running through the art of the region today.
The exhibition was part of Middle East Now, a season of special events which includes lectures, films, poetry readings and music. The exhibition and the season were produced in partnership with Dubai Holding.

Science & Engineering Research Center
The goal of Potomac's Science and Engineering Research Center program is to provide our students with the opportunity to do high-level, independent research projects.
Students conduct in-depth study and research of an original topic and address a question previously unanswered in science or engineering. Students work one-on-one with our faculty and with an outside mentor, typically a professional scientist. A summer internship at a research facility or university for 4-8 weeks is a requirement and an important component of the program. Our students have had mentors and internships at a variety of labs including The National Institutes of Health, the J. Craig Ventor Institute, Georgetown University, Yale University, the University of Minnesota, the University of Maryland, and John Hopkins University among others.
In tenth grade, the students who are selected into the program are enrolled in two courses:
1) The Topics in Science and Engineering course begins the program by having the students explore various fields of research and engage in projects that allow them to examine the steps required to properly structure an experiment or project in order to adequately test a hypothesis. When students are reasonably sure of their direction, they contact professionals working within their area of interest and then read current research papers in order to refine their topics. Visits to MIT and also local universities and research facilities expose the students to a range of research fields and provide contacts with possible mentors. The students will complete a formal project proposal for the research they will conduct in their junior and senior years.
2) The Accelerated Integrated Chemistry and Physics course provides students with an integrated, quantitative overview of chemistry and physics. Through problemsolving, mathematical modeling, and laboratory work, the students will learn the core, critical concepts of chemistry and physics and the key features that unify the two disciplines. The central role of mathematics as a universal language of science is emphasized. Upon successful completion of the course, students in the SERC track will be prepared to take Advanced Placement Chemistry and Advanced Placement Physics in their future years at Potomac.
In eleventh grade, students will again take two courses:
1) AP Biology or AP Chemistry or AP Physics
2) Advanced Science Research, which provides the students with an individualized opportunity to pursue the research question they proposed at the end of their tenth grade year. The students have a class period each day dedicated to working on their projects. Ideally, students will have both a Potomac science teacher and an outside mentor advising them during the school year. Students are expected to spend time in the summer after eleventh grade working with their outside mentor or taking part in a science research internship program. The time commitment for the summer work or internship is usually six weeks.
In twelfth grade, students will take one or two AP science courses and finish their research by documenting and presenting their work. Some students will elect to submit their research findings to national competitions including the Siemens Competition, the Intel Talent Search, and the Georgetown Symposium. The SERC program is selective. Interested students may apply in the spring of their ninth grade year.
Recent SERC Projects
Polyurethane digestion by fungi
The discovery of microorganisms that can efficiently degrade polyester polyurethane (PUR) has become a pivotal goal in promoting bioremediation as an applicable solution to plastic waste. Endophytic fungi were isolated from a variety of plants on campus and tested on their ability to digest polyurethane (PUR) in soluble or insoluble form. Members of the Glomerella and Cladosporium genera were found to grow on PUR as sole carbon source in both conditions. Current experiments are underway to characterize the activity of the enzyme responsible for this digestion, as well as the transcriptional differences in the fungi grown under varied environmental conditions.
Protein 3D modeling to explain cytoplasmic sequestration of nuclear proteins
This project focused on the cytoplasmic protein 14-3-3 s and the nuclear regulator fox-o1, two are known regulators of cellular pathways. The goal was to generate visual models of the interactions between foxo1 and 14-3-3σ. The main software used were I-TASSER modeling to generated full-length 3d conformations of foxo1, and Rosetta dock to model the interactions between the two proteins. The simulations suggested that the prongs of 14-3-3σ attract the foxo1 consensus binding site revealed by phosphorylation, in a manner similar to a horseshoe magnet attracting a dipole.
Effect of the plastic additive BHT on the growth and development of drosophila melanogaster Additives to plastic have become essential to achieve specific properties. Some of these additives include heat stabilizers, antioxidants, lubricants, and anti-static agents. These chemicals can leach in the environment and become toxic, questioning their safety. This project focuses on testing the effect of one such additive on the growth and development of the fruit fly, drosophila melanogaster.
PCR test for Lyme disease
Lyme disease is an infectious, vector-born disease that affects the lives of over 300,000 people in the United States every year. The current testing works well under ideal conditions - sufficient, measurable quantities of the antibodies after an incubation period after the initial infection. However, it also leads to both false-positives and false-negative diagnosis and the need for a new diagnostic test that is more efficient, effective, and reliable is high. This project aims at developing a PCR test for Lyme disease with high sensitivity and specificity to target strands of Borrelia burgdorferi in a patient's blood sample.
Encapsulating islet cells in a hydrogel matrix with extracellular matrix (ECM) proteins, heparin, and
Type 1 diabetes (t1d) is a chronic illness that is caused by an autoimmune reaction resulting in the loss of insulin-producing β-cells in pancreatic islets. This project focuses on the encapsulation of pancreatic islet cells within a hydrogel capsule bonded with heparin, vascular endothelial growth factor (VEGF-a), transforming growth factor beta 1 (TGFβ-1), and components from the extracellular matrix (ECM), such as collagen and laminin.
Mangrove based water filtration system
Clean water is an essential resource, being a prerequisite for human life. As the human population continues to grow, the demand for clean water will increase accordingly, aggravating the problem of fresh water availability throughout the world. Aquaporins are membrane proteins that regulate water transport through cells and they promote permeability orders of magnitude higher than commercial membranes when embedded in synthetic polymers. The incorporation of these proteins into a proven system, a biomimetic mangrove structure, could yield higher efficiency in water desalination.
Chloroplast symbiosis has been described as the mechanism by which how the sea slug, Elysia chlorotica lives photosynthetically. Like sea slugs use photosynthesis to create energy, yeast uses fermentation to make ethanol. Yeast is a unique organism because they choose fermentation even in the presence of oxygen, and they react in a variety of environmental settings. It is also the main organism used in biofuel production as carbohydrate sources are fed to the yeast for ethanol production. The goal of this project is to implant a photosynthetic system into a fermentative organism.
Improving the efficiency of solar cells
Using phosphorescent algae, solar cells electrical output will be measured to evaluate its efficiency. The goal of this study is to expand the time solar cells can be used, since phosphorescent algae emit light at night.
Improving tactile sensitivity in prosthetic hands and robotic systems
The current technology for robotic and prosthetic hands in terms of tactile sensitivity is developing but not widely accessible. Will mimicking the ridges of a human fingerprint improve tactile sensitivity in prosthetic fingers? This project researches what type of sensors are ideal for gaining tactile sensitivity in prosthetic fingers (capacitive, piezoelectric, force sensitive) and what design of the artificial fingerprint will provide the best tactile sensitivity in the prosthetic fingers.
Optimizing photocatalysts for solar-fuel production by altering nanostructures
Solar energy is one of the most promising renewable energy technologies for its potential to provide carbon-free energy on the terawatt scale. However, one of the most significant problems facing the integration of solar energy is efficiently converting it into chemical fuels for storage. This project analyzes the effects of different nanoarchitectures on a basic cobalt catalyst in a photoelectrochemical cell and their relation to the photocatalytic properties of a certain material?
Effect of short wavelengths of light on ab-42 fibril formation
Alzheimer's disease is known to be caused by plaque deposition in the brain. These plaques are fibrils that polymerize from short peptides known as ab-42 and resemble fibrils that have been characterized in prion disorders. Prion fibril formation has been shown to be sensitive to UV light. This study analyzes the effect of UV light on the formation of fibrils from the ab-42 peptide.

Chondrogenesis In Human Mesenchymal Progenitor Cells Derived From
War-Traumatized Muscle Tissue Within A Fibrin Hydrogel Scaffold
Regeneration of cartilage in the clinical treatment of traumatic extremity wounds aims at implanting engineered tissue at the site of injury. The most promising technique currently involves combining cells of stem cell lineage with biocompatible scaffolds in order to promote reliable differentiation of the cells in the patient. The purpose of this study is to analyze whether the presence of hyaluronic acid (ha) promotes chondrocyte differentiation from human mesenchymal progenitor cells (MPCs) in an engineered fibrin matrix supplemented with increasing concentration of ha.

In this paper, a novel receiver architecture is proposed for multiple-input-multiple-output (MIMO) systems; the proposed architecture helps achieve superior performance in multipath fading channels when the number of layered streams exceeds the number of receiving antennas. In this architecture, the concept of "virtual channel" is adopted to attain diversity gain even when successive detection is applied for reducing computational complexity, while orthogonal frequency division multiplexing (OFDM) is employed to combat multipath fading. Actually, successive detection is carried out in all possible virtual channels, and the virtual channel with the minimum error probability is detected with the assistance of the maximum a-posteriori (MAP) decoder in the architecture. In addition, soft input and soft output (SISO) iterative detection is introduced in the virtual channel estimation scheme. The performance of the proposed architecture is verified by computer simulations. This architecture can be implemented with lesser complexity than that in maximum likelihood detection (MLD), but the gain in the former case exceeds that in the latter by 4.5 dB at the BER of 10-3 for 42 MIMO-OFDM.

LINQ Element Operators
Element operators is the name that Microsoft gives to this group of LINQ methods: First, FirstOrDefault, Single and SingleOrDefault.
In-Memory behavior:
The behavior of this methods in-memory is clear:
0 elements 1 element N elements
FirstOrDefault null element first element
First EXCEPTION element first element
SingleOrDefault null element EXCEPTION
Single EXCEPTION element EXCEPTION
Example:
List<ProjectEntity> projects = //...
project.Single();
And LINQ to Signum also does exactly that, but only if the query ends in one of this operators. Example:
Database.Query<ProjectEntity>().Single(); //Throws EXCEPTION if 0 or N elements
The problem comes when the operator is in the middle of a LINQ to Signum query:
In-Database behavior:
In the middle of a LINQ to Signum query there's no easy way to throw an exception, for example:
from b in Database.Query<BugEntity>()
let c = b.Comments.Single()
select new { b.Description, c.Text };
This query is going to be translated to some SQL, but is not cost-effective to throw exceptions for a particular BugEntity with more (or less) than just one comment.
One alternative that we consider was to translate the four operators to the behavior of FirsOrDefault when in-database, using OUTER APPLY and TOP(1):
SELECT bdn.Description, s2.Text
FROM BugEntity AS bdn
OUTER APPLY (
 (SELECT TOP (1) bdnc.Text
 FROM BugDNComments AS bdnc
 WHERE (bdn.Id = bdnc.idParent))
) AS s2
But having the same translation for the fourth operators is a loss of expressiveness:
 - If you know that there will be always more than zero related rows, the OUTER APPLY could be replaced by CROSS APPLY.
 - If you know that there will never be more than one related row, so the TOP(1) is unnecessary.
So what we did instead is to re-interpret the behavior of the four operators, replacing EXCEPTION -> QRMNS (Query Results Make No Sense).
0 elements 1 element N elements
FirstOrDefault null element first element
First QRMNS element first element
SingleOrDefault null element QRMNS
Single QRMNS element QRMNS
So when you write:
from b in Database.Query<BugEntity>()
let c = b.Comments.Single()
select new { b.Description, c.Text };
It will be translated to:
SELECT bdn.Description, s1.Text
FROM BugEntity AS bdn
CROSS APPLY (
 (SELECT bdnc.Text
 FROM BugDNComments AS bdnc
 WHERE (bdn.Id = bdnc.idParent))
) AS s1
This is a beautiful simple query, like the one you could write by hand if you know that there's always exactly one comment for each bug. But notice that, even if let is not meant to increase or reduce the number of results:
 - If there are bugs without comments, The bugs itself will disappear!!
 - IF there are bugs with more than one comment, The bugs will be duplicated!!.
In other words, you'll be able to write slightly cleaner queries, but think that instead of getting exceptions in the error cases, you'll get malformed queries.
 - If you know that there will never be more than one element (i.e: There's a UniqueIndex) you can use SingleXXX instead of FirstXXX.
 - If you know that there will always be some elements and null is impossible, feel free to remove OrDefault. Except in a expressionMethod.
Avoid Single in expressionMethod
Avoid using Single if you're writing an expressionMethod since could be an extension over a potentially null object.
Example:
Imagine we have an inverted relationship between BodyEntity and HeadEntity. The HeadEntity refers to the BodyEntity with his Body column, that has a UniqueIndex. This looks like a sensible expressionMethod:
static Expression<Func<BodyEntity, HeadEntity>> HeadExpression =
 p => Database.Query<HeadEntity>().Single(h=>h.Body.Is(b));
[ExpressionField]
public static HeadEntity Head(this BodyEntity b)
{
 return HeadExpression.Evaluate(b);
}
 - We can use SingleOrDefault instead of FirstOrDefault because we know that there not be two HeadEntity pointing to the same Body (thanks to the UniqueIndex in HeadEntity.Body).
 - If we are sure that there will always be a HeadEntity for each BodyEntity, we could be tempted to use Single instead of SingleOrDefault, but avoid this in expression because you have no control of BodyEntity b being null.
Imagine that a CarEntity has an optional BodyEntity Driver property and someone writes this query:
Database.Query<CarEntity>().Select(c => c.Driver.Head()).ToList();
The writer of this query doesn't know the implementation of Head, and will expect this query to return null for the parked cars without driver, but if we implement Head using Single, the parked cars will disappear!
So, as a general rule, choose FirstOrDefault, First, SingleOrDefault or Single in queries you have total control of, but avoid Single on expressionsMethod since the input parameter could be null.
Finally, if you think this is just too complicated, use FirstOrDefault always inside of the queries, it's the only operator of the four ones that can be accurately translated to SQL.
SingleEx, SingleOrDefaultEx, FirstEx
Signum.Utilities defines alternative methods for Single, SingleOrDefault and First in EnumerableExtensions that return more expressive exception messages than the BCL counterparts.
All this methods are also equally supported in the LINQ provider.

The University of South Australia (UniSA) with two Adelaide-based SMEs, VPG Innovation and SMR Australia,…
South Australia will become a hub for an in-space manufacturing industry after California-based Varda Space Industries and Southern Launch announced a partnership to conduct re-entry operations at the Koonibba Test Range. The first such mission is scheduled for mid-2024.
Varda Space Industries is building the world's first commercial microgravity industrial park at scale. The company develops in-orbit production equipment as well as economical reentry capsules. It aims to develop life-saving pharmaceuticals in space and return the goods to Earth using the company's specialised return capsule. The natural advantages of the space environment, in particular microgravity and vacuum, enable the production of goods that cannot be manufactured on Earth. Varda Space
In addition, Varda partners with the US Air Force, Navy, and NASA to utilize its reentry capsules as a testing platform for hypersonic and reentry technologies.
Southern Launch Chief Executive Officer Lloyd Damp said, "In-space manufacturing is the next evolution of humanity's industrial capacity, and elements produced in-orbit have the potential to change the course of history."
The Koonibba Test Range, which Southern Launch operates in partnership with the Koonibba Community Aboriginal Corporation, offers over 23,000 square kilometres of uninhabited land to accept the re-entry of in-space manufacturing capsules. US based Varda Space Industries will use the range to conduct a re-entry operation as soon as its second orbital mission, scheduled for mid-2024.
"Our partnership with the Koonibba Test Range is a great example of the ongoing collaboration between the United States and Australia within aerospace and defence," said Varda Space Industries CEO Will Bruey.
Southern Launch will support Varda Space Industries to conduct high cadence re-entry operations at the Koonibba Test Range to meet a wide range of Varda's customer needs.
Looking to the future, Southern Launch hopes South Australia can become the global hub for in-space manufacturing thanks to the company's two unique space sites that together can accommodate the launch and subsequent return of in-space manufacturing vehicles.
"The opportunities for South Australia are immense," said Lloyd Damp. "It's likely that by the end of this decade everyday Australians will use products with parts manufactured in orbit. This makes space the resource industry of the future and we have the potential to expand on Australia's high-tech manufacturing industry and develop the consumer end products right here in Australia.'
The first re-entry of a Varda Space Industries capsule to the Koonibba Test Range is scheduled for mid-2024, subject to regulatory approvals.

Can You Tell What This Is? (Photos)
A London-based architect created a remarkable design for a yacht, called the Tetrahedron Super Yacht.
The futuristic vessel, designed by Jonathan Schwinge, levitates due to a vertical strut that's attached to a torpedo-shaped hull -- and includes an outdoor dining area, a significant amount of deck space and a "flying speed" of 38 knots.
The vessel is made from carbon fiber and stainless steel, and can accommodate six passengers and four crew members. Schwinge said his design allows for the yacht to travel smoothly through rough waters.

"The design is instigated by the rethinking of the form, superstructure and propulsion of the modern superyacht into a radically simple enclosure and an elevated mode of travel above the water line," Schwinge said in a statement.
"A three-based pyramid consisting of four faces and six leading edges provides fundamental stability and enclosure. Its form produces a pure, precise, logical and mathematical "roof" for which to connect to the hull assembly. Generally, simple forms are not known in ship and motor yacht construction through restrictions in ocean-going hull design. Long distances are achievable with reduced out-of-water drag and stormy ocean conditions would incur virtually no slamming."

Why is it hard to fight in dreams?
You cant throw a punch because your body is basically temporarily paralysed during REM, so that you wont be able to hurt yourself. … You cant throw a punch because the your subconscious is holding you back. Most of the threats that we face in dreams are the representations of the issues we have in our real lives.
Why are my punches so weak in my dreams?
Your brainstem usually paralyzes your muscles when you're sleeping, and sometimes the feeling of not being able to move can translate into your dreams. … So your brain is getting the response that you haven't actually thrown a punch, and in your dream you get the sensation that it's "weak".
Why do we fight so slow in dreams?
Every time I'm dreaming and try to punch something or someone it always ends up being a heavy, slow-motion flail that does nothing… Why is this? It's because punching (like running) is a highly-coordinated activity that relies on proprioceptive feedback throughout the motion to work.

In a separate entry, it also says: To dream that you are trying to run but cannot make your feet move as fast as you want them to, signifies lack of self-esteem and self-confidence. It may also reflect your actual state of REM paralysis while in the dream state.
Why do my punches feel weak in a fight?
The primary reason is adrenaline. Adrenaline prepares you for a fight by turning your survival mode on. So your brain doesn't let you feel the intense pain that you normally would feel when you punch someone. So because you don't feel the pain in your hand, you automatically think you didn't hit your enemy hard enough.

Explaining interspecific differences in sapling growth and shade tolerance in temperate forests
*Author to whom correspondence should be addressed: Frank J. Sterck. Tel.: +31 317478046. Fax: +31 317478078. E-mail: _EMAIL_.
- 1Species differences in growth and shade tolerance might contribute to coexistence of tree species. To explore how such differences depend on underlying plant traits, 14 tree species were investigated in temperate forests on sand and loess soils in the Netherlands. Plant traits were measured for 0.5–1 m tall saplings: 10 saplings growing at low light conditions and 10 at high light conditions. Growth was determined from annual lengths of leader shoots, and shade tolerance from an independently tested scale.
- 2Shade tolerance and extension growth of the leader shoot were negatively correlated. Plant traits that related positively with shade tolerance were negatively related to extension growth, and vice versa. Photosynthetic capacity, leaf dark respiration and total leaf mass related weakly to shade tolerance and extension growth. Specific leaf area (SLA, leaf area/leaf mass) and wood density were the traits most strongly correlated to shade tolerance and extension growth.
- 3Shade-tolerant species had denser wood and slower extension growth. They also had larger crowns, suggesting that dense stems provide strength for supporting larger crowns.
- 4More shade-tolerant species had a higher SLA, which is opposite to tree communities with larger leaf life span variation. In winter deciduous tree communities, more shade-tolerant species benefit from investing leaf area at low costs (high SLA) rather than from investing in durable leaves (low SLA).
- 5Species on sand had higher growth rates and higher light requirements than species on loess. In line with the resource-ratio hypothesis, the dominance of the more shade-tolerant species on nutrient rich loess soils may be attributed to the denser vegetation supported and the resultant lower light availability for saplings compared with saplings on infertile and drought-prone sand soils.
- 6Synthesis: These results provide plant trait-based predictions for the regeneration success and composition of species of temperate forests with management based on natural regeneration. These forests are expected to become dominated by shade-tolerant species with high wood density and high SLA on the more productive soils, and by light demanding species with low wood density and low SLA on poorer soils.


Month-over-Month data in Splunk
Image icon 9-2-2015 9-39-06 AM.png24.56 KB
I've been working with Splunk Enterprise a lot lately (and it's very powerful and easy to use!). In many situations, it is useful to show some metric compared to the same metric a month ago (or some other time period).
One way to accomplish this is with the community-supported Splunk app, Timewrap. I couldn't get Timewrap to output the data as I wanted, so instead here's the approach that I used.
Here's my goal:
Splunk Screenshot
Before we compare data from the current period to the previous period, we need to ensure the dates are consistent. This example compares data from the current day to a previous day. If you want to compare current month/year to previous month/year, refer to the Splunk documentation for the bin command.
index=foo | bin _time span=1d
Now we use the stats command to perform the comparison.
| stats count(eval(relative_time(now(), "_USER_")=_time)) as "Current Period" count(eval(relative_time(now(), "-30d@d")=_time)) as "Previous Period" by category
 - For "Current Period", count the events where the _time field is equal to midnight today. Remember, we just standardized all events to equal midnight of the respective day.
 - For "Previous Period", count the events where the _time field is equal to midnight 30 days ago.
If this is useful to you, or you have any more suggestions, please let me know in the comments below.

You will now be presented with a blank analysis tab:
Here there are two things unique to the GUI which need to be preformed:
- NMR frequency label:
- First set the NMR frequency label.
This is only used for the name of the output file.
For example if you set the label to "1200", the file r1.1200.out will be created at the end of the analysis.
- Results directory:
- All of the automatically created results and Grace files will be placed into this directory.
The "Results directory" can now be changed.

The lineGatherDigits function initiates the buffered gathering of digits on the specified call. The application specifies a buffer in which to place the digits and the maximum number of digits to be collected.
LONG WINAPI lineGatherDigits( HCALL hCall, DWORD dwDigitModes, LPSTR lpsDigits, DWORD dwNumDigits, LPCSTR lpszTerminationDigits, DWORD dwFirstDigitTimeout, DWORD dwInterDigitTimeout );
Handle to the call on which digits are to be gathered. The application must be an owner of the call. The call state of hCall can be any state.
Digit modes to be monitored. This parameter uses one or more of the LINEDIGITMODE_ Constants.
Pointer to the buffer where detected digits are to be stored as text characters. Digits may not show up in the buffer one at a time as they are collected. Only after a LINE_GATHERDIGITS message is received should the content of the buffer be assumed to be valid. If lpsDigits is NULL, the digit gathering currently in progress on the call is terminated and dwNumDigits is ignored. Otherwise, lpsDigits is assumed to have room for dwNumDigits digits.
Number of digits to be collected before a LINE_GATHERDIGITS message is sent to the application. The dwNumDigits parameter is ignored when lpsDigits is NULL. This function fails if dwNumDigits is zero.
Null-terminated string of termination digits as text characters. If one of the digits in the string is detected, that termination digit is appended to the buffer, digit collection is terminated, and the LINE_GATHERDIGITS message is sent to the application.
The list of valid characters is dependent on the constant provided in dwDigitModes. For a list of the valid characters for each possible mode, see LINEDIGITMODE_ Constants.
If this pointer is NULL, or if it points to an empty string, the function behaves as though no termination digits were supplied.
Time duration in milliseconds in which the first digit is expected. If the first digit is not received in this timeframe, digit collection is aborted and a LINE_GATHERDIGITS message is sent to the application. The buffer only contains the NULL character, indicating that no digits were received and the first digit timeout terminated digit gathering. The call's line-device capabilities specify the valid range for this parameter or indicate that timeouts are not supported.
Maximum time duration in milliseconds between consecutive digits. If no digit is received in this timeframe, digit collection is aborted and a LINE_GATHERDIGITS message is sent to the application. The buffer only contains the digits collected up to this point followed by a NULL character, indicating that an interdigit timeout terminated digit gathering. The call's line-device capabilities specify the valid range for this parameter or indicate that timeouts are not supported.
Returns zero if the request succeeds or a negative error number if an error occurs. Possible return values are:
LINEERR_INVALCALLHANDLE, LINEERR_NOMEM, LINEERR_INVALCALLSTATE, LINEERR_NOTOWNER, LINEERR_INVALDIGITMODE, LINEERR_OPERATIONUNAVAIL, LINEERR_INVALDIGITS, LINEERR_OPERATIONFAILED, LINEERR_INVALPARAM, LINEERR_RESOURCEUNAVAIL, LINEERR_INVALPOINTER, LINEERR_UNINITIALIZED.
Digit collection is terminated when the requested number of digits has been collected. It is also terminated when one of the digits detected matches a digit in szTerminationDigits before the specified number of digits has been collected. The detected termination digit is also placed in the buffer and the partial buffer is returned.
Another way of canceling digit collection occurs when one of the timeouts expires. The dwFirstDigitTimeout expires if the first digit is not received in this time period. The dwInterDigitTimout expires if the second, third, (and so forth) digit is not received within that time period from the previously detected digit, and a partial buffer is returned.
A fourth method for terminating digit collection is by calling this function again while collection is in progress. The old collection session is terminated, any digits collected up to that point are copied to the buffer supplied from the previous call to this function, and the buffer is delivered when the LINE_GATHERDIGITS message is sent to the application. The mechanism for terminating digit gathering without initiating another gathering of the digits is to invoke this function with lpsDigits equal to NULL.
This function is considered successful if digit collection has been correctly initiated, not if digit collection has terminated. In all cases where a partial buffer is returned, valid digits (if any) are followed by a NULL character.
Although this function can be invoked in any call state, digits can typically only be gathered while the call is in the connected state.
The message LINE_GATHERDIGITS is sent only to the application that initiated the request. It is also sent when partial buffers are returned because of timeouts or matching termination digits, or when the request is canceled by another lineGatherDigits request on the call. Only one gather-digits request can be active on a call at any given time across all applications that are owners of the call. Given the asynchronous behavior of the operation, an application that issues multiple lineGatherDigits requests in quick succession may be able to do so and receive several LINE_GATHERDIGITS messages later. While this would be unusual application behavior, the application is able to count the number of these messages to allow cancel messages to be matched with the earlier requests. In any case, only the most recent request should be assumed to be valid.
Note When an application invokes any asynchronous operation that writes data back into application memory, the application must keep that memory available for writing until a LINE_REPLY or LINE_GATHERDIGITS message is received.
An application can use lineMonitorDigits to enable or disable unbuffered digit detection. Each time a digit is detected in this fashion, a LINE_MONITORDIGITS message is sent to the application. Both buffered and unbuffered digit detection can be simultaneously enabled for the same call.
Gathering of digits on a conference call applies only to the hConfCall, not to the individual participating calls.
If the lineGatherDigits function is used to cancel a previous request to gather digits, the function copies any digits collected up to that point to the buffer specified in the original function call. The function then sends a LINE_GATHERDIGITS message to the application, regardless of whether the lpszDigits parameter in the second call specifies a NULL or different address.

Professor David O'Connor's lab at the University of Wisconsin uses LabKey Server as its "operating system," speeding its efforts to understand how genetics affects immunity to viruses such as HIV/SIV.
The lab uses LabKey Server to manage its extensive list of experiments, Illumina sequencing data, purchases, oligonucleotides, freezer samples, and other lab inventory, as well as to provide basic electronic lab notebook (ELN) functionality. Data, files, protocols, grant information, and experiment descriptions recorded on the server can be searched and queried, allowing lab members to look across experiments performed over more than ten years to find what they need quickly.
Further, the server hosts an informational portal for an NIH-funded contract on major histocompatibility complex (MHC) genetics, allowing different subsets of data to be exposed to the scientific community and the funding agency.
LabKey Server enables the lab to automate genotyping workflows for efficiency and consistency; perform comprehensive review of available genomic and clinical information for primate subjects; and gain analysis, querying, visualization, export, and search capabilities across many different data types. Today, the system helps the lab track data and metadata for tens of thousands of experiments, eliminate manual workflows, and securely share data with collaborators.
In February of 2016, the O'Connor lab became the first group to make real-time Zika data publicly available via their LabKey Server. Results are updated daily and are accessible online through the Zika experimental science team (ZEST) data portal.

Today, the Guam Homeless Coalition and the Guam Housing and Urban Renewal Authority is conducting a one-day count of the island's homeless. About 150 volunteers will be dispersed throughout the island to help discern the island's homeless population.
The annual event is used to determine about how many people in Guam don't have homes, or live in substandard housing. It's a requirement because the local government receives Continuum of Care funding from the federal government.
Guam's homeless numbers have been high in recent years. In 2011, there were 1,541 homeless. Last year's count was 1,301. And the counts are never fully complete, as not all homeless individuals are identified in the one-day events, so it's possible the numbers are even higher.
There are some agencies and nonprofit groups that offer services and other assistance to the homeless. On a regular basis, an event called Passport to Services is held to aid the island's homeless and those at risk of homelessness, as well as other needy individuals. Agencies, nonprofits and volunteers give out food bags and toiletries, offer free haircuts and help individuals obtain identification cards, among other services.
But only a fraction of the island's homeless and needy show up, primarily because they don't have a reliable way to get to the event -- or to any agency or nonprofit offering assistance. The island's mass transit system is hugely inadequate, with limited routes, limited buses and long waits.
If elected officials truly want to help the island's homeless, people with disabilities and others in need, they must work to bolster, expand and improve public transportation. They must not allow the current situation to persist.
It won't be easy or inexpensive to fix public transportation, and it won't happen quickly. But this has been a longstanding problem that has continually been ignored by elected officials. And that has to change.
