Abstract The ecological impact of artificial light at night (ALAN) on phenological events such as reproductive timing is increasingly recognized. In birds, previous experiments under controlled conditions showed that ALAN strongly advances gonadal growth, but effects on egg-laying date are less clear. In particular, effects of ALAN on timing of egg-laying are found to be year-dependent, suggesting an interaction with climatic conditions such as spring temperature, which is known have strong effects on the phenology of avian breeding. Thus, we hypothesized that ALAN and temperature interact to regulate timing of reproduction in wild birds. Field studies have suggested that sources of ALAN rich in short wavelengths can lead to stronger advances in egg-laying date. We therefore tested this hypothesis in the great tit (Parus major), using a replicated experimental setup where eight previously unlit forest transects were illuminated with either white, green, or red LED light, or left dark as controls. We measured timing of egg-laying for 619 breeding events spread over six consecutive years and obtained temperature data for all sites and years. We detected overall significantly earlier egg-laying dates in the white and green light versus the dark treatment, and similar trends for red light. However, there was a strong inter-annual variability in mean egg-laying dates in all treatments, which was explained by spring temperature. We did not detect any fitness consequence of the changed timing of egg-laying due to ALAN, which suggests that advancing reproduction in response to ALAN might be adaptive.
Artificial light at night, in interaction with spring temperature, modulates timing of reproduction in a passerine bird

There are many dimensions to systemic change. The following aspects of systemic change are considered important in the Vincentian Family
- Involving the poor themselves, including women and young people, at all stages: the identification of needs, planning, implementation, evaluation and revision;
- Having a holistic vision — addressing a series of basic human needs: individual and social, spiritual and physical, especially jobs, health care, housing, education, and spiritual growth — with an integral approach toward prevention and sustainable development;
- Placing particular emphasis on self-help and self-sustaining programs, with a special view toward addressing the root causes of poverty.

- Sharing Stories of Social Change PBS site
Not every aid project exemplifies systemic change. (see "Concept" section above for ways it is being understood in the Vincentian Family.)
OneWorld "Indian Social Entrepreneur of the Year 2007" offers some criteria for examples of systemic change that could be adapted for the projects in the Vincentian Family.
- 1. Innovation
- You have brought about social change by transforming traditional practice. Such transformation has been achieved through
- • An innovative product or service
- • The development of a different approach, or
- • A more determined or rigorous application of known technologies, ideas and approaches.
- A salient characteristic of a social entrepreneur is developing a pattern-changing idea and implementing it successfully.
- 2. Sustainability
- Your innovation has generated the social conditions and/or institutions needed to sustain the initiative and you are dedicating all of your time to it.
- • If set up as a non-profit entity, your organization is achieving some degree of financial self-sustainability through fees or revenues or is engaged in creating mutually beneficial partnerships with business and/or the public sector. Where possible, economic incentives are embraced. In any case, there is a clear difference from traditional charity and a move towards community-based empowerment and sustainability. There is also a difference with traditional business.
- • If set up as a for-profit entity, the orientation toward social and environmental value creation predominates, with financial return treated as a secondary means to an end, rather than an end in itself.
- 3. Direct social impact
- You have founded, developed and implemented the entrepreneurial initiative directly, together with poor or marginalized beneficiaries and stakeholders. The Impact of your work manifests itself in quantifiable results and testimonials and is well documented. There are no significant negative externalities.
- 4. Reach and Scope
- The initiative has spread beyond its initial context and has been adapted successfully to other settings in the country or internationally, either by your organization, or through others who have replicated or adapted elements of it.
- 5. Replicability
- The initiative can be adapted to other regions of the world to solve similar problems. As an entrepreneur you are open to sharing with others the tools, approaches and techniques that are critical to the adaptation of the initiative.

Calculation of the neutron noise using the Analytical Nodal Method
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2009
In this study, the neutron noise, i.e. the stationary fluctuations of the neutron flux around its mean value, is calculated in 2-group diffusion theory for a 2-dimensional reactor using the Analytical Nodal Method. A brief description of the calculation of the static flux is also included. The same calculational scheme for the neutron noise as for the static flux is used. As a benchmark, the calculated neutron noise for a 2-dimensional fully homogeneous reactor is compared with the analytical solution which can easily be determined for homogeneous reactors. The result of the benchmark is that the numerically calculated neutron noise accurately matches the analytically calculated neutron noise.

Bayesian Tactile Exploration for Compliant Docking With Uncertain Shapes
Kris Hauser
Abstract:
This paper presents a Bayesian approach for active tactile exploration of a planar shape in the presence of both localization and shape uncertainty. The goal is to dock the robot's end-effector against the shape -- reaching a point of contact that resists a desired load -- with as few probing actions as possible. The proposed method repeatedly performs inference, planning, and execution steps. Given a prior probability distribution over object shape and sensor readings from previously executed motions, the posterior distribution is inferred using a novel and efficient Hamiltonian Monte Carlo method. The optimal docking site is chosen to maximize docking probability, using a closed-form probabilistic simulation that accepts rigid and compliant motion models under Coulomb friction. Numerical experiments demonstrate that this method requires fewer exploration actions to dock than heuristics and information-gain strategies.

Paris: Let's talk about homelessness
Avec une couverture au dessus d'un vélo, la personne se abrite dans une entrée de garage, 9ème Arrondissement de la capitale françaises.
Emergency shelter with a bike and a blanket in the 9th district of Paris (Urbanauth/ 2019)
3552 homeless people got counted in the capital of Paris this year.
At the annual "Nuit de la solidarité" (night of solidarity)in Paris between January and February, volunteers are on the streets for one night to count homeless people and, as far as possible, ask them about their living situation. Organised by the city and in partnership with various large associations, the figures mainly provide an insight into the different profiles and zones of homelessness.
3641 homeless people got counted at one night in the streets in 2019
Introduced in 2018, it is one of the few references on homelessness in the French capital and follows a methodology. In addition to the census, it also attempts to understand the needs and backgrounds of those affected, as well as the geographical location of their accommodations. The APUR, Parisian Urbanism Authority, published its study on the 2nd Nuit de la solidarité (2019) in December. Urbanauth has taken a look inside for you.
The volunteers did not exclusively count people sleeping in the street, but also those in places such as train stations or parking lots. So for 2019 the statistics included the so-called green lungs of the capital, the Bois de Boulogne in the west, and the Bois de Vincennes in the east, as well as the "Colline" in the north. Unfortunately, the numbers are not definite, as the census only takes place on one day. The results may therefore vary and do not represent the absolute number of homeless people.
The study could only count in accessible places. Consequently it excluded areas of petite ceinture or parks and silent occupations. Also invisible from the statistics are all persons who are "couchsurfing" and who are sleeping at solidarity networks. Furthermore only 2000 out of 3600 homeless in the study received the questionnaire. So about half of the respondents replied with a complete or partial answer.
What does homelessness in the French Capital looks like?
Des pigeons se rassemblent à un mètre de l'abri le long de l'immeuble.
A DIY space in the 17th Arrondissement between a wall and a energybox (Urbanauth/2019)
The study primarily looks at gender, age ranges and whether the person was encountered individually or as part of a group. Secondary observations regarded pregnancy, families, minors/children and animal companions. Thereafter, it was tried to identify the forms of homelessness among the interviewees and to understand their life situation.
Overall, 36% of the people recorded have been homeless for less than a year. With a share of 10 % young people (>25 years old) belong to a particularly vulnerable group. They are for example the least aware of social services like emergency shelters, social benefits, accompaniment of social workers. Also, young people usually arrived in Paris without any accommodation. This is why this group is temporary homeless, and got sighted mostly in the 18th arrondissement. They are also among those who tend not to have habitual places to sleep. In contrast to those who have been living on the streets for a long time.
For the interviewees, the reasons for homelessness were mostly their arrival in the capital without suitable accommodation, followed by blows of fate, separations and evictions. 14% of those interviewed were women, with the highest proportion of women in the age groups of under 25 and over 55 years. These women mostly stay in groups and change their sleeping places frequently. For them and the under 25 years old, it is the most dangerous to be homeless.
The hotspot is located in the north-east of Paris
Paris with its 20 districts by homeless people. (Map: APUR / December 2019)
Except the 15th district in the southwest, the highest concentration of homelessness is in the north-east. The 18th district is home to the largest group, with 507 people living on the streets, 105 of them residents of the "Colline", a notorious hill at the motorway junction and a humanitarian problem. The tent village at the Porte de la Chapelle, where refugees and crack addicts are living in tents on the brown line next to the highway, is regularly evacuated. However, in the absence of measures in the form of accommodation and prospects, new people are constantly moving in. The dissolution of the crack addicts camp for homeless people in autumn 2019 has contributed to the distribution of these people over a larger area. For example to public places in the north, such as the Canal de l'Ourcq or the Jardin d'Éole (19th arr.) and Porte d'Aubervilliers. 2017 / 2018 there was also a huge tent camp, which stretched from the canal at Quai Valmy to the suburbs of Saint Denis, and a Sinti and Roma camp on the Petite Ceinture between Porte Clignancourt and Porte de la Chapelle. These two spatial occupations have since been evacuated, possibly leading to a redistribution to the north of Paris and the neighbouring suburbs such as Bobigny, Pantin, La Courneuve and Bondy.
To the south, bordering the 18th district, are the 9th and 10th arrondissements with a population of 110 and 359 people. Following the 19th (466), 11th (176), 20th (156) and ends with the 12th district (369). The latter shows 167 additional homeless people who have taken shelter in the Vincennes forest. The concentration of a high proportion of homelessness correlates with the so-called popular districts. These areas have got a high cultural diversity, but also a high proportion of social housing and poverty. In comparison to the previous year, an exodus from the 9th and 10th districts to the north can be observed.
A decrease of homeless people in these districts is noteable, while a significant increase happened in the 18th and 19th districts. In this area, more groups of young people were counted, which are most strongly represented in both areas. The mass of homeless people decreases in the south-western part of the city and shows a mixed personal profile. The 16th arrondissement, which is considered a very bourgeois district, has borders on the equally rich suburb of Boulogne. Some homeless people have been counted in the Boulogne forest, although this is much smaller than in the "Colline" or the Vincennes forest. The latter is located in the east and borders the 13th arrondissement, which also has a certain homelessness.
The north-south axis to the west and the belt in the centre from the 2nd to the 8th district are conspicuous by their low number of homeless people. These are also so-called "Beaux Quartiers" / the beautiful and expensive quarters. The city puts a lot of effort to clear such districts from poverty. 2017 Urbanauth witnessed the evacuation of a Sinti and Roma shelter on an unused railway line at the Pont Cardinet (17th Arr.).
04.03.2020 The article got actualized with the number of homeless people in 2020. (FranceBleu)

My last blog introduced the idea of using Microsoft Visual Studio Code to work with Power BI Models. For this article, I build on that idea by showing how you can use a TOM based script to automatically generate measures in your model Power BI (or Azure Analysis Services) model.
For simplicity, the example in this blog will do the following:
– Connect to an instance of Power BI Desktop
– Iterate through every Table in the model
– Iterate through every Column in the "current" table from the outer loop
– If the Column is numeric and not hidden, create a simple [Sum of ] measure
Read on for demonstration code and a walkthrough of the process.

VDO is software that provides inline block-level deduplication, compression, and thin provisioning capabilities for primary storage. VDO installs within the Linux device mapper framework, where it takes ownership of existing physical block devices and remaps these to new, higher-level block devices with data-efficiency properties. Specifically, VDO can multiply the effective capacity of these devices by ten or more. These benefits require additional system resources, so it is therefore necessary to measure VDO's impact on system performance.
Storage vendors undoubtedly have existing in-house test plans and expertise that they use to evaluate new storage products. Since the VDO layer helps to identify deduplication and compression, different tests may be required. An effective test plan requires studying the VDO architecture and exploring these items:
VDO-specific configurable properties (performance tuning end-user applications)
Impact of being a native 4 KB block device
Response to access patterns and distributions of deduplication and compression
Performance in high-load environments (very important)
Analyze cost vs. capacity vs. performance, based on application
Failure to consider such factors up front has created situations that have invalidated certain tests and required customers to repeat testing and data collection efforts.
31.1.1. Expectations and Deliverables
This Evaluation Guide is meant to augment, not replace, a vendor's internal evaluation effort. With a modest investment of time, it will help evaluators produce an accurate assessment of VDO's integration into existing storage devices. This guide is designed to:
Help engineers identify configuration settings that elicit optimal responses from the test device
Provide an understanding of basic tuning parameters to help avoid product misconfigurations
Create a performance results portfolio as a reference to compare against "real" application results
Identify how different workloads affect performance and data efficiency
Expedite time-to-market with VDO implementations
The test results will help Red Hat engineers assist in understanding VDO's behavior when integrated into specific storage environments. OEMs will understand how to design their deduplication and compression capable devices, and also how their customers can tune their applications to best use those devices.
Be aware that the procedures in this document are designed to provide conditions under which VDO can be most realistically evaluated. Altering test procedures or parameters may invalidate results. Red Hat Sales Engineers are available to offer guidance when modifying test plans.


ché la decrittografia dei dati durante il download nel client.The Azure Storage Client Library for .NET Nuget package supports encrypting data within client applications before uploading to Azure Storage, and decrypting data while downloading to the client. La libreria supporta anche l'integrazione con l'insieme di credenziali delle chiavi di Azure per la gestione delle chiavi dell'account di archiviazione.The library also supports integration with Azure Key Vault for storage account key management. Ecco una breve descrizione del funzionamento della crittografia lato client:Here is a brief description of how client side encryption works:
 - Azure Storage Client SDK genera una chiave di crittografia del contenuto (CEK) che funziona come chiave simmetrica monouso.The Azure Storage client SDK generates a content encryption key (CEK), which is a one-time-use symmetric key
 - I dati del cliente vengono crittografati con la chiave CEK.Customer data is encrypted using this CEK
 - Viene quindi eseguito il wrapping della chiave CEK mediante la chiave di crittografia della chiave (KEK).The CEK is then wrapped (encrypted) using the key encryption key (KEK). La chiave KEK è identificata con un identificatore di chiave e può essere costituita da una coppia di chiavi asimmetriche o da una chiave simmetrica. Può essere gestita localmente o archiviata nell'insieme di credenziali delle chiavi di Azure.The KEK is identified by a key identifier and can be an asymmetric key pair or a symmetric key and can be managed locally or stored in Azure Key Vault. Il client di archiviazione non ha mai accesso alla chiave KEK.The Storage client itself never has access to the KEK. Richiama solo l'algoritmo di wrapping della chiave fornito dall'insieme di credenziali chiave.It just invokes the key wrapping algorithm that is provided by Key Vault. Volendo, i clienti possono scegliere di usare provider personalizzati per il wrapping o la rimozione del wrapping delle chiavi.Customers can choose to use custom providers for key wrapping/unwrapping if they want
 - I dati crittografati vengono quindi caricati nel servizio Archiviazione di Azure.The encrypted data is then uploaded to the Azure Storage service. Per informazioni dettagliate sull'implementazione, vedere i collegamenti riportati nella sezione dei riferimenti.Check the links in the references section for low-level implementation details.

Two bronze dōtaku (ritual bells), Yayoi period (about 300 BC-AD 300), Japan.
The origin of the dōtaku is thought to be the Chinese cattle bell. However, the Japanese did not practise cattle farming, so the first bells must have been imported as ritual objects. The fact that they are often found buried on isolated hill-sides and show evidence of having been buried and dug up several times, suggests their use in an agricultural ritual. - britishmuseum.org


Who invented the 1st submarine and what was it called

 When it came to wartime machines, Leonardo DaVinci often seemed to look at both sides of the coin. He would invent offensive equipment and then he would design defensive equipment just in case the enemy had similar ideas to him. A good example of this is in the double-hulled and semi-submersible (sometimes termed Leonardo's submarine) boat designs.
 The'submarine' was simply a shell with room enough for one person to sit inside. It was topped with a conning tower which had a lid and pre-dated the true submarine by over one hundred years. Leonardo was to describe it as a "ship to sink another ship."
 Leonardo considered that the best way to defend against underwater attack by ships similar in design to his'submarine' was to have double-hulled boats. This would not only solve the problem of ramming, but also that of divers interfering with the vessel. By this time he had already devised a method by which divers could separate the planks of ships.
 He considered how lost ships could be recovered, and designed air-filled tanks which divers could attach to the hulls of a sunken ships in an attempt to re-float them. And once your ship is once more on the surface you need to remove the excess water. Leonardo then designed a machine which would extract the water and then dry the holds of ships.
 His designs included a one-man battleship, and in considering ships for wartime use Leonardo realised the importance of making guns easier to load and fire. This same drawing displays two remote-control guns with rapid-firing mechanisms.
 I need to start getting paid for this. For crying out loud, Survivor is on!
 John Hunley, and the submarine was called the Hunley. It was built during the civil war.
 Hunley Sub was built in 1861 but Hunley wasn't the INVENTOR of the Submarine nor the first to NAME ONE.
 I stand corrected, But I think the question was what was the name, not who named one.
 You know what they say about those submariners........A hundred men go down.....fifty couples come up.
 I thought the first submarine was a one man unit called the turtle...

Britain to treble tree planting by 2024
Britain will treble its tree planting rates over the next three years to help reach its target of net zero carbon emissions by 2050, and combat climate change.
George Eustice, UK environment secretary, is set to announce that more than 17,000 acres of woodlands would be planted per year.
His statement read:
But it gave no other details regarding how many trees would be planted or where, or how much the planting scheme would cost or how it would be funded.
The statement also did not give a comparison figure for how many acres of woodland had been planted previously.
Britain is due to host the COP26 conference in Glasgow in November.The UK government said it was focused on four goals: securing global net zero, protecting communities and natural habitats from the impacts of climate change, mobilizing finance, and nations working together to accelerate action.
Britain's climate tsar and COP26 President Alok Sharma warned that world leaders must agree to end coal use at the November summit to prevent a climate catastrophe.
"Human activity is damaging our Earth. It is imperilling this brilliant jewel. The greenhouse gases that we've been pumping into the atmosphere since the Industrial Revolution are altering nature's precious balance, disrupting the finely tuned and fantastically complex system that is the world's climate.''

Incorporated Trustee
DEFINITION of 'Incorporated Trustee'
A corporation, usually a trust company, which is named as the trustee of a private trust or other fiduciary account. Incorporated trustees stand in contrast to an individual person or "natural trustee," who may also be selected as the trustee of such an account. In both cases, the trustee's role is to execute the instructions of the trust's grantor as well as manage the assets of the trust.
BREAKING DOWN 'Incorporated Trustee'
There are two primary advantages of appointing an incorporated trustee. First, since corporations theoretically never die or become incapacitated, they will likely outlast individual trustees. Second, since professional trustees focus all their time on this role, they're typically more knowledgeable about the role and less likely to mismanage the trust. The two primary disadvantages are the costs of professional trust management and a lack of understanding for the grantor's unexpressed wishes.

Lamium galeobdolon (synonym: Lamiastrum galeobdolon)
Yellow archangel is a fast growing perennial plant in the Lamiaceae (mint) family. It is often planted as an ornamental in residential areas, but it easily escapes and invades natural areas. It is evergreen to semi-evergreen and typically trailing or growing over other plants. The flowers are small, yellow, and they grow close to the stems. The leaves are opposite, hairy, often variegated with silver-gray marking, and the margins are toothed. The stems can root at the nodes, and as a member of the mint family, the stems are also square. It spreads by seed and stem fragments.
Height of mature plants
1 – 2 feet
April – June
Yellow archangel looks somewhat similar to goutweed. However, the variegation on goutweed is typically closer to the margins and it has white flowers that are smaller than those of yellow archangel.
Yellow archangel grows well in full sun to full shade, in a variety of soil types, and in dry or moist sites. It can be found in ravines, forested parks, residential areas, and greenbelts.
Yellow archangel can form extensive mats of ground cover, which out compete native species. These mats provide poor food and cover for wildlife. Its above-ground stems can grow 3 feet per year, giving it an advantage in finding light resources. Disturbance seems to stimulate plant growth.

Resetting Bluetooth Module on Mac: How to Fix Connection
Erik Blandford,
Macs like other devices use Bluetooth for wireless connecting with such things as mice, keyboard, trackpad etc. It is assumed to be a reliable way but sometimes there is a chance you have a problem when establishing a Bluetooth connection. Many of such problems may be easily fixed just by unpairing and changing batteries. After that reboot your Mac (use SMC reset) and done! But if it does not work, do not worry. A great way out will to reset network settings and here is how.
Quick Solution
There are two specific problems with connectivity that users usually experience:
 1. Bluetooth devices which are not able to pair with yours.
 2. Bluetooth devices that paired successfully, but are not working for some reason.
In both cases, the possible reason is the corruption of the preference list your Mac uses for storing Bluetooth devices and the present state of these devices. However, the fix is easy: create a backup of your data and just delete the bad preference list.
How to Reset Bluetooth Module
Before you proceed with resetting, remember that if your setup uses just Bluetooth to communicate with your mouse and keyboard, then you may temporary lose this connection (use the wired option if needed). So what should you do?
 1. Hold the shortcut commander Shift + Option (Alt), then press the Bluetooth symbol located in the top-right corner of the menu bar. (If you cannot find it there, then click Show Bluetooth in menu bar in your settings)
 2. Press Reset the Bluetooth module.
 3. Reboot your Mac.
That is it. As you can see, everything is easy. And what do you think?

Export Colab to CSV
Jump to
 Overview
 Welcome to our comprehensive guide on exporting data from Google Colab to CSV files, a valuable skill for data scientists and analysts who wish to share, analyze, and collaborate on data more effectively. By converting Colab notebooks into CSV format, users can leverage the simplicity and compatibility of CSV files to easily load data into spreadsheets and various data analysis tools. In this guide, we will explore what Google Colab is, the step-by-step process of exporting your data frames to a CSV file, practical use cases for this method, an alternative approach using Sourcetable, and a helpful Q&A section to address common inquiries about the process.
 What is Colab?
 Google Colaboratory, or Colab, is a hosted Jupyter notebook service that provides free access to computing resources and is well-suited to machine learning, data analysis, and education. As a product from Google Research, Colab allows users to write and execute Python in their web browser with zero configuration required, free access to GPUs, and easy sharing.
 Colab notebooks are stored in Google Drive and can be shared just like documents in Google Docs. This service is aimed at simplifying the process of working with machine learning tools and data sets, and it is designed to promote collaborative projects in the field of education and research.
 While Colab is a free service, it does come with limitations. Resources are not guaranteed and are not unlimited. Activities may be terminated without warning, particularly those that bypass its anti-abuse policies. Colab also offers options such as Colab Pro, Pro+, and Pay As You Go for users who require more resources or increased compute availability.
 Exporting Data from Colab to CSV
 Saving Dataframes as CSV
 You can export dataframes created in Google Colab into CSV files by utilizing the pandas library's to_csv method. This is done by calling df.to_csv('filename.csv') on the dataframe you wish to save. This line of code converts the dataframe into a CSV file with the specified filename.
 Downloading CSV Files to Local Computer
 After saving the dataframe as a CSV file, you can download it to your local computer. This is achieved by using the Google Colab files functionality. Simply execute files.download('filename.csv') to initiate the download of the CSV file you created.
 Downloading CSV Files to Google Drive
 To save your CSV files directly to Google Drive, you need to first install PyDrive by running !pip install -U -q PyDrive. Once installed, you can authorize and create a connection to Google Drive, list the files and folders, and upload your CSV file using file.Upload(). Make sure to save the dataframe with df.to_csv('mydataframe.csv', sep='\\t') if you want to specify a tab separator, and use the code snippet provided to find the ID of the folder where you want to save your file in Google Drive.

Using the LAARIS* technology, in collaboration with Celine & Cain Kitsais, Warp is the first of its kind Interactive Laser Manipulation act.
This version was created to experience weight and real physics simulation of the laser objects created.
It was also the first creation where fusion between dance and laser is thought in terms of methodology.
The main question was :
Is it best to think "dance and movement" first, then program the laser around ?
Or "interaction with laser" first, then create the choreography accordingly ?
The answer is not so simple, but we experienced the different work method,
and come with a unique "hybrid methodology"…

Here we present a method for classifying fMRI independent components (ICs) by using an optimized algorithm for the individuation of noisy signals from sources of interest. The method was applied to estimate brain activations from combined EEG-fMRI data for the exploration of epilepsy. Spatial ICA was performed using the above-mentioned optimized algorithm and other three popular algorithms. ICs were sorted considering the value: of the coefficients of determination R2, obtained from the multiple regression analysis with morphometric maps of cerebral matter; of the kurtosis, which features the signal energy. The validation of the method was performed comparing the brain activations obtained with those resulted using the General Linear Model (GLM). The ICA-derived activations in different datasets comprised subareas of the GLM-revealed activations, even if the volume and the shape of activated areas do not correspond exactly. The method proposed also detects additional negative regions implicated in a default mode of brain activity, and not clearly identified by GLM. Compared with a traditional GLM approach, the ICA one provides a flexible way to analyze fMRI data that reduces the assumptions placed upon the hemodynamic response of the brain and the temporal constrains.

Difference Between A Men's Hairdresser and A Barber
Google+ Pinterest LinkedIn Tumblr
Fancy haircuts and hairstyles have been around for as long as recorded history. Razors can be traced back to 3500 BC, the Bronze Age, and the popularity of barbers was seen to soar in the mid-twentieth century. No one will deny the fact that they don't require a haircut, whether its men or women. We all require haircut to look good, to look decent and that's why we need those specialists who can cut our hairs as per our preference and style. Thus, we require the services of hairdressers and barbers frequently. Especially men, as their hair grows fast and thus to look decent they have to regularly have a haircut. But there is a thing, there is a hell lot of confusion when it comes to differentiating between a men's hairdresser and a barber. Now, we have heard both terms but there is a catch, they both are different. They both are involved with haircutting and haircare, but modernization and other factors have made it more complex terms and thus to get a clear picture, it is important to have a differentiation sorted out so that one can get clear about both of them. But before we forward with the differentiation part, let's understand what hairdresser and barber really are.
A person who has special training for cutting, styling, and washing their client's hairs is called a hairdresser. Hairdresser is not gendered specific, a male, as well as a female, can perform the task. It is used as a universal term that can be applied to a person whose occupation is to give new styles to their client's hair and to cut and maintain them. Hairdresser is also used as a synonym for hairstylist and they work in salons, parlors, fashion events and movie sets. They are not restricted to just cutting and styling hairs, but they also perform the task of coloring, washing, shampooing and other hair related treatments to their clients.
Those who possess the skill sets and who are trained for cutting a men's hair are known as barbers. The word barber is extensively used to describe an expert who specializes in the grooming of men which includes, shaving, trimming of beard, and maintaining mustaches. If we look upon the history of the professionals called barbers then it goes back to ancient times, as men required grooming.
Points of Difference between a Men's Hairdresser and Men's Barber:
Barber is an older term than that of a hairdresser.
 - If we have looked upon on the work of both, barbers and hairdressers perform the same task and that is to cut hairs, but the only significant difference between them is that the barber cuts only men's hair.
 - Barber's profession is to look after the grooming needs of men which includes haircutting, trimming, shaving, beard, and mustache cutting. Whereas a hairdresser can be associated with a unisex job, as they work for both the men and the women and they specialize in grooming need of both.
 - A hairdresser is also called as a hairstylist and to acquire the skills they have the license of a barber as well as cosmetology.
 - When we talk about the training part, barbers and hairdressers, undergo the altogether different set of training. Barbers trains especially for grooming needs and hairstyles of men.

Points in General Position
Many Discrete Geometry problems study planar point sets in general position. Most commonly, this definition refers to point sets with no three collinear points and no four cocircular points (that is, no circle contains four points of the set). A few examples of such problems:
 - What is the minimum number of distinct distances that are spanned by a set of n points in general position?
 - What is the minimum number of convex k -gons determined by n points in general position?
 - For even n , what is the maximum number of distinct ways in which one can cut a set of n points in general position by a line into two halves, each of cardinality n/2 ?
 - What is the maximum number of points that can be placed on an n \times n grid so that no three points are collinear. What happens when we also forbid four cocircular points?
Randomly choosing n points from the plane will lead to a set in general position, but this set is unlikely to have any interesting extremal structure. For example, we expect such a set to span many distinct distances, and it is not clear why such a set should span few convex k -gons. Problems such as the ones above ask for point sets that are in general position while also having some kind of structure. I often find it useful to have examples of such point sets as part of my "Discrete Geometry toolkit". I am familiar with two very different constructions of such sets. This post describes these two constructions. If you are familiar with additional constructions, do let me know!
Construction 1: Subsets of the integer lattice. Our first construction involves finding a large subset of an n \times n section of the integer lattice that is in general position. The basic idea for this construction seems to originate from Erdős (for example, see this paper of Roth), although we will follow a later variant of Thiele.
For a prime p , we consider the point set
{\cal P} = \left\{\left(t,t^2 \mod p\right)\ :\ 0\le t <p/4 \right\}.
Note that {\cal P} is a set of \lfloor p/4\rfloor points from a p\times p section of the integer lattice. We will now show that {\cal P} does not contain three collinear points or four cocircular points.
Thiele
An example of the first construction, created by Gábor Damásdi.
Three points (x_1,y_1),(x_2,y_2), and (x_3,y_3) are collinear if and only if
\begin{vmatrix} 1 & x_1 & y_1 \\ 1 & x_2 & y_2 \\ 1 & x_3 & y_3 \end{vmatrix} = 0.
It is not difficult to check that for three points (t_1,t_1^2),(t_2,t_2^2),(t_3,t_3^2) , we get
\begin{vmatrix} 1 & t_1 & t_1^2 \\ 1 & t_2 & t_2^2 \\ 1 & t_3 & t_3^2 \end{vmatrix} = (t_2-t_1)(t_3-t_2)(t_3-t_1).
For distinct integers t_1,t_2,t_3 , this determinant is clearly nonzero. When we also have that 0\le t_1,t_2,t_3 < p , this determinant is also not a multiple of the prime p . Thus,
\begin{vmatrix} 1 & t_1 & (t_1^2 \mod p) \\ 1 & t_2 & (t_2^2 \mod p) \\ 1 & t_3 & (t_3^2 \mod p) \end{vmatrix} \neq 0.
We conclude that no three points of {\cal P} are collinear. We can use a similar argument for the case of cocircular points. Four points (x_1,y_1),(x_2,y_2),(x_3,y_3), and (x_4,y_4) are cocircular if and only if
\begin{vmatrix} 1 & x_1 & y_1 & x_1^2 +y_1^2\\ 1 & x_2 & y_2 & x_2^2 +y_2^2\\ 1 & x_3 & y_3 & x_3^2 +y_3^2\\ 1 & x_4 & y_4 & x_4^2 +y_4^2 \end{vmatrix} = 0.
(One can think of this test is as lifting the four points to the paraboloid defined by z=x^2+y^2 in {\mathbb R}^3 , and checking if the four lifted points are coplanar. It is known that the intersections of the paraboloid with planes are exactly the lifting of circles to the paraboloid.)
Taking the points (t_1,t_1^2),(t_2,t_2^2),(t_3,t_3^2),(t_4,t_4^2) , we get
\begin{vmatrix} 1 & t_1 & t_1^2 & t_1^2 +t_1^4\\ 1 & t_2 & t_2^2 & t_2^2 +t_2^4\\ 1 & t_3 & t_3^2 & t_3^2 +t_3^4\\ 1 & t_4 & t_4^2 & t_4^2 +t_4^4 \end{vmatrix} = (t_1+t_2+t_3+t_4)\prod_{1\le j<k \le 4}(t_k-t_j).
Since 0\le t_1,t_2,t_3,t_4 < p/4 , we have that t_1+t_2+t_3+t_4 is not a multiple of p . Assuming that the four integers are distinct, none of the elements of the product is a multiple of p . Repeating the above argument, we get that no four points of {\cal P} are cocircular.
Now that we know that the above construction is in general position, let us mention a few of its applications:
 - Erdős and Purdy asked for the size of the largest subset of the n\times n integer lattice with no three points on a line and no four on a circle. The above construction provides the current best lower bound for this problem.
 - Erdős, Hickerson, and Pach asked whether there exists a planar set of n points in general position that spans no parallelograms and still determines o(n^2) distinct distances. Dumitrescu provided a positive answer to this question by using the above construction.
 - The Heilbronn triangle problem asks for the smallest \Delta(n) such that every set of n points in the unit square determine a triangle of area at most \Delta(n) . Erdős used a variant of the above construction to produce one of the first non-trivial lower bounds for the problem.
Construction 2: Projection from a hypersphere. In our first construction, the point set has some structure since it is a subset of a p\times p section of the integer lattice. The structure in our second construction also originates from a lattice, although in a very different way. This construction comes from a paper of Erdős, Füredi, Pach, and Ruzsa, and seems to be influenced by earlier ideas of Behrend.
For a positive integer d , consider the section of the d -dimensional integer lattice
{\cal L} = \left\{(x_1,\ldots,x_d)\in {\mathbb Z}^d :\ 0\le x_1,\ldots,x_d <2^d \right\}.
We claim that there exists a hypersphere around the origin that contains many points of {\cal L} . First, note that |{\cal L}| = 2^{d^2} . We also note that the distance between a point x\in {\cal L} and the origin is \sqrt{x_1^2+\cdots+x_d^2} . Every such distance is the square root of an integer between zero and d\cdot 2^{2d} . That is, the points of {\cal L} determine at most d\cdot 2^{2d} distinct distances from the origin. By the pigeonhole principle, there exists a distance \delta such that at least 2^{d^2}/(d\cdot 2^{2d})=2^{d(d-2)}/d points are at distance \delta from the origin. In other words,

Down syndrome occurs in about 1 in 700 births. Children with
typical development learn to walk independently at about 12 months of age.
Those with Down syndrome typically learn to take independent steps at 24-28
months. Getting infants walking is critical
because this can delay the emergence other skills such as social skills, motor
skills, advancement of perception and spatial cognition.
According to the Center for Motor
Development at the University of Michigan, babies with Down Syndrome can learn
to walk earlier and better using a treadmill. In
the study, 30 infants were randomly assigned lower intensity, generalized treadmill
training, or high intensity, individualized treadmill training. The exercise
therapy was implemented in the homes by their parents. The exercise therapy was
used as a supplement to physical therapy. High intensity training included
increasing the treadmill belt speed, using longer durations, and adding light
weights to the ankles, with intensity tailored to each child. The parent sat on
a bench that straddled the treadmill and held the infant as the child took
steps on the treadmill. The duration of the exercise therapy was for eight
minutes a day, five days a week for three months.
Dale Ulrich, the director of the
Center for Motor Development at the University of Michigan suggests if
children with Down Syndrome are able to walk earlier and better, they are
able to explore their environment and learn about the world around them. He
also agrees that walking is a critical factor in the development of other
domains. Treadmills are about $1,200 each. The hope is that more hospitals and
Down syndrome parent organizations will rent the equipment to parents.

Embodied energy analysis can be used as a construction design assessment tool in a sustainable matrix for a building. Its implementation however remains challenging mainly because of data measurement errors. A comparison between the deterministic embodied energy (EE) of a building and the stochastic EE of the same building undertaken using Monte Carlo simulation showed a wide variation in results. It is recommended that the specification of EE intensity of building materials in the construction industry can assist in producing accurate and more credible EE values of building.

Usage
Usage for simple cases is very similar as with Tastypie. You should read their tutorial first.
The main difference is when you are defining API resource files. There you must use MongoEngineResource instead of ModelResource.
Simple Example
from tastypie import authorization
from tastypie_mongoengine import resources
from test_app import documents
class PersonResource(resources.MongoEngineResource):
 class Meta:
 queryset = documents.Person.objects.all()
 allowed_methods = ('get', 'post', 'put', 'delete')
 authorization = authorization.Authorization()
Defining fields
Most document fields are automatically mapped to corresponding Tastypie fields but some are not. Of course, you can also manually define (override) those automatically mapped fields if, for example, you want to define some read-only.
Warning
When manually defining resource fields be careful to properly map MongoEngine attributes to Tastypie attributes. For example, required and null attributes are inversed in meaning, but both are by default False.
Warning
When manually defining resource fields be careful not to forget to set attribute to document's field name. It is not set automatically and if it is not set it is assumed that you will be processing this field manually (in for example, resource's hydrate method).
Some fields cannot be mapped automatically so you have to define them manually. Like related and embedded fields, but special fields like SequenceField as well:
sequence_field = tastypie_fields.IntegerField(attribute='sequence_field')
EmbeddedDocument
When you are using EmbeddedDocument in your MongoEngine documents, you must define object_class in Meta class of your resource declaration instead of queryset:
class EmbeddedPersonResource(resources.MongoEngineResource):
 class Meta:
 object_class = documents.EmbeddedPerson
 ...
When you are using normal MongoEngine Document you can use queryset or object_class.
Polymorphism
MongoEngine supports document inheritance and you can normally add such inherited documents to your RESTful API. But sometimes it is useful to have only one API endpoint for family of documents so that they are all listed together but that you can still create different variations of the document. To enable this, you have to define mapping between types and resources. For example, if documents are defined as:
class Person(mongoengine.Document):
 meta = {
 'allow_inheritance': True,
 }
 name = mongoengine.StringField(max_length=200, required=True)
 optional = mongoengine.StringField(max_length=200, required=False)
class StrangePerson(Person):
 strange = mongoengine.StringField(max_length=100, required=True)
You might define your resources as:
class StrangePersonResource(resources.MongoEngineResource):
 class Meta:
 queryset = documents.StrangePerson.objects.all()
class PersonResource(resources.MongoEngineResource):
 class Meta:
 queryset = documents.Person.objects.all()
 allowed_methods = ('get', 'post', 'put', 'patch', 'delete')
 authorization = authorization.Authorization()
 polymorphic = {
 'person': 'self',
 'strangeperson': StrangePersonResource,
 }
Use self keyword to refer back to the current (main) resource. Authorization and other similar parameters are still taken from the main resource.
Then, when you want to use some other type than default, you should pass it as an additional parameter type to Content-Type in your payload request:
Content-Type: application/json; type=strangeperson
Alternatively, you can pass a query string parameter.
All this works also for embedded documents in list.
Polymorphic resource_uri
By default, polymorphic resources are exposed through the API with a common resource_uri.
In the previous case, PersonResource and StrangePersonResource are both exposed through the /<api_version>/person/ resource URI.
But in some cases, you may want to expose your resources through the polymorphic resource uri. To use this behaviour, you should set the prefer_polymorphic_resource_uri meta variable to True.
You might define your resources as:
class IndividualResource(resources.MongoEngineResource):
 class Meta:
 queryset = documents.Individual.objects.all()
 allowed_methods = ('get', 'post', 'put', 'patch', 'delete')
 authorization = tastypie_authorization.Authorization()
 paginator_class = paginator.Paginator
class CompanyResource(resources.MongoEngineResource):
 class Meta:
 queryset = documents.Company.objects.all()
 allowed_methods = ('get', 'post', 'put', 'patch', 'delete')
 authorization = tastypie_authorization.Authorization()
 paginator_class = paginator.Paginator
class ContactResource(resources.MongoEngineResource):
 class Meta:
 queryset = documents.Contact.objects.all()
 allowed_methods = ('get', 'post', 'put', 'patch', 'delete')
 authorization = tastypie_authorization.Authorization()
 prefer_polymorphic_resource_uri = True
 polymorphic = {
 'individual': IndividualResource,
 'company': CompanyResource,
 }
You might now reference both resources:
class ContactGroupResource(resources.MongoEngineResource):
 contacts = fields.ReferencedListField(of='test_project.test_app.api.resources.ContactResource', attribute='contacts', null=True)
 class Meta:
 queryset = documents.ContactGroup.objects.all()
 allowed_methods = ('get', 'post', 'put', 'patch', 'delete')
 authorization = tastypie_authorization.Authorization()
And for each contact listed, the:
 - IndividualResource would be dehydrated to /<api_version>/individual/<id>/
 - CompanyResource to /<api_version>/company/<id>/
Warning
The ContactResource could not be registered but be careful to register all the resources present in the polymorphic dict otherwise the dehydrated resource_uri will point to the parent resource.

Grid pricing has advantages, but don't participate without thorough knowledge.
Recently, there has been increased emphasis on improving the quality and consistency of beef. Cattle producers, breed associations, feed suppliers and packers have initiated value-based pricing methods commonly referred to as grid pricing. While these various schemes may differ substantially in the carcass traits they seek to reward or penalize, they all have one common feature: price is established on each individual animal based on carcass merit.
With most grids, price is discovered after animals have been slaughtered. With a few exceptions, most grids are based on dressed weights for fed cattle. Unlike live weight pricing or dressed weight "in the beef" pricing where there is a single average price for the entire sale lot, a price is discovered for each animal with grid pricing.
As a result, higher quality cattle receive higher prices and lower quality cattle receive lower prices. Thus, cattle producers who market desirable types of cattle are rewarded.
Most grids consist of a base price with specified premiums and discounts for carcasses whose quality perform above and below the base or standard quality specifications. An example is shown in Table 1, but does not represent the grid for any specific packer or marketing alliance.
Some grids may provide added premiums for carcasses meeting specifications of Certified Angus Beef or other marketing programs. Likewise, packers may specify discounts for hide damage, injection site blemishes and other "out" or unmarketable carcasses.
To compute a grid-based price, the distribution of carcasses by quality grade (QG) and yield grade (YG) from a sale lot of fed cattle must be known. That distribution also is put into a matrix framework.
A hypothetical distribution of carcasses for a 100-head sale lot of steers is shown in Table 2. The hypothetical pen is a fairly typical pen of cattle — 65% QG Choice and Prime, and 60% YG 1 and 2.
Once the base price is known for the grid in Table 1, the net price for a pen of cattle can be computed by multiplying the percent of carcasses in each matrix cell in Table 2 by each premium and discount cell in Table 1. For example, if the base price is $110/cwt. of dressed weight, then the weighted average price for the pen distribution in Table 2 is $109.68/cwt. See Figure 1. We assumed there were no "out" carcasses. The actual net price for a pen of cattle may vary from the calculated price due to differences in carcass weights.
Some other thoughts:
 - A higher base price is probably more critical to receiving a higher net price from a grid than are the specific premiums and discounts. The base price affects all cattle in the sale lot, whereas premiums and discounts affect only selected carcasses.
 - Many grids compute the base price using the previous week's cash price. These formula base prices don't contribute to price discovery and provide packers an incentive to lower cash market bids.
 - Formula base prices tied to the Chicago Mercantile Exchange Live Cattle Futures or to the wholesale beef market price are preferable to formulas based on fed cattle cash prices. Preferably, base prices can be negotiated weekly in the fed cattle market and contribute to competition and price discovery.
Pricing And Management Issues
 - Without knowledge of the cattle's carcass quality, marketing on a grid may be disappointing and risky. Grids can provide an incentive to market higher quality cattle, but the penalty for not recognizing and marketing lower quality cattle is large.
 Even a few lower quality cattle, priced at large discounts to higher quality cattle, can offset the premiums for higher quality cattle. The bottom line results might be a price that is lower on average than a live weight or dressed weight cash price.
 Cattle quality significantly affects the bottom line price results when marketing by a grid. For example, in Table 2 there are 30 head of Prime and Choice, YG 1 and 2 carcasses. Using the grid in Table 1, they add a premium of $1.08/cwt. to the base price.
 Table 1. Example grid in a completed matrix format. ($/dressed cwt.) Base price is $110/cwt.
 Yield Grade
 Quality Grade 1 2 3 4 5
 Prime 11 9 6 -14 -19
 Choice 5 3 Base -20 -25
 Select -1 -3 -6 -26 -31
 Standard -11 -13 -16 -36 -41
 Dark Cutters -20
 Light Carcasses (< 550 lbs.) -10
 Heavy Carcasses (> 950 lbs.) -20
 Table 2. Example Distribution of Carcasses by Quality and Yield Grades (100 Head Total).
 Yield Grade
 Quality Grade 1 2 3 4 5 Total
 Prime 0 1 5 3 0 9
 Choice 6 23 26 1 0 56
 Select 10 19 5 0 0 34
 Standard 1 0 0 0 0 1
 Total 17 43 36 4 0 100
 Fig. 1. Example of grid pricing calculations.
 Yield Grades
 1 2 3 4
 Prime $119 × 1 + $116 × 5 + $96 × 3 = $987
 Choice $115 × 6 + $113 × 23 + $110 × 26 + $90 × 1 = $6,239
 Select $109 × 10 + $107 × 19 + $104 × 5 = $3,643
 Standard $99 × 1 = $99
 $10,968 100 head = $109.68 Net price/cwt.
 Also in Table 2, there are four YG 4 and one Standard carcasses. These five discounts reduce the base price by 96¢/cwt., nearly offsettinxg the premiums from 30 higher quality carcasses.
 - Should pens of cattle be sorted to fit different grids or sorted to sell some cattle on the cash market? Sorting cattle to fit different grids may be economical provided a producer has a good idea how the different groups of sorted cattle will perform in carcass form. Sorting off "out" or lower quality cattle just before marketing them and mixing them with a pen of cattle sold on an average live weight or dressed weight price is a shortsighted approach to marketing.
 Profit from sorting may be higher for both pens but, over time, packers will likely bid lower for the cash market cattle. However, sorting cattle earlier may enable the feeder to manage both pens of cattle to meet specifications in more than one grid. This management change may reduce feeding costs, increase returns and enhance shortand long-term profitability.
 - Producers must realize that if feeding and other management practices are altered, then receiving the highest price doesn't imply the greatest revenue. Nor does the greatest revenue imply the largest profit.
Revenue is price multiplied by weight, and profit is revenue minus costs. To maximize profit on a pen of cattle, the selling weight and feeding costs need to be considered, in addition to the selling price.
Grid pricing methods have become more common in recent years. Grids have the advantage of pricing each animal, thereby improving pricing accuracy. Cattle are paid on actual dressed weights and the price is adjusted for carcass traits. Better quality cattle are rewarded and poorer quality cattle are penalized.
While grid pricing has definite advantages, producers need to know the quality of their cattle and how grids are calculated before knowing whether grid pricing is advantageous for them. Producers also must consider profit (cost and revenue) implications of altering feeding practices to target specific grids.
