Digital Image Registration and Comparison
←Older revision | Newer revision→
This page has been written as part of the NIP2 Beginners Guide.
Image registration is the process of ensuring that the matching features of two similar images appear in the same place in each image. If different images have been captured of a single object, at different stages of it's life, for example before, during or after conservation work or with different pieces of equipment, for example visible, infra-red, uv or x-ray, then they may need to be registered to each other before direct digital comparisons are carried out.
Image comparison is the process of checking whether the matching features of two similar images appear in the same place in each image. Comparisons can be used to check the result of the registration procedures or just to check if two similar images match, this can very useful when comparing different versions of the same painting, or even checking whether a drawing or cartoon has been used in the construction of a painting.
There are two basic registration function included in nip2, Linear Match and Perspective Match. Two images need to be selected and then the chosen function can be performed, the second image will be adjusted to match the first based on the positioning of a set of marks.
Figure 8.1: Selection of sample images used to show the results of the image overlay and image registration functions. Image A is the base image that the others starting images, B, C and D want to be resistered to. Images AA, AB, AC and AD are the result of running the overlay function with image A and all of the starting images. Images B2 and C2 show the results of linear matching images B and C with image A and image D2 show the results of perspective matching images C with image A. Images AB2, AC2 and AD2 are the result of running the overlay function with image A and the three matches images.
- [Main Window][Toolkits: Image: Transform: Linear Match]
This functions can be used to correct size, translation and rotation differences between two images. Two marks are placed on each of the original images, which can be moved to indicate the position of two good matching features in the images. In addition to the marks options are provided to lock the image to prevent resizing[_TAG_ 1] and to allow the software to try to improve the position of your marks[_TAG_ 2].
- [Main Window][Toolkits: Image: Transform: Perspective Match]
This functions can be used to correct size, translation, rotation and perspective distortion differences between two images. Four marks are placed on each of the original images, which can be moved to indicate the position of four good matching features in the images.
There are three basic comparison function included in nip2, Overlay, Slider Blend and Along Line, see figure [_TAG_:reg_comp 8.2]fg:reg_comp. Two images need to be selected and then the chosen function can be performed for the comparison to be performed.
Figure 8.2: Examples of the nip2 objects produced by the three basic comparison functions, Overlay, Slider Blend and Along Line.
- [Main Window][Toolkits: Filter: Overlay]
This function produces a mono version of the original object and then uses them along with a black image to produce a RGB[_TAG_ 3] colour image. By default the first image is used to create the red chanel, the second image is used to create the green chanel and the black is used for the blue channel, this is know as Green over Red. Here the good areas of overlap will appear yellow, where the green and red images match, see figure [_TAG_:reg_regandcomp 8.1]fg:reg_regandcomp and figure [_TAG_:reg_comp 8.2]fg:reg_comp. The function object does provide the option to change this image order to produce different colours if it is required.
- [Main Window][Toolkits: Filter: Blend: Slider Blend]
This function effectively places the second image on top of the first and then allows the user to adjust the transparency of the second image by moving a slider back and forward.
- [Main Window][Toolkits: Filter: Blend: Along Line]
This function produces an new image by blending then together down a line. Options are provided for the user to decided if the images are to be blended left-right or top-bottom and to control the position and degree of the blend.
This can be good if you are wanting to line two images up but not actually change their size. This process does not always improve your match but can be helpful at times. see section [_TAG_:colour 3.3.3]sec:colour

PEMF Butterfly coil
PEMF butterfly coil
What is a Butterfly coil and what is its use?

The name Butterfly coil is derived from the form for this type of coil. Alternatively this coil is also called a "Figure 8 coil", the name being self-explanatory.

The main reason why this kind of coil has been developed is for applications where deep and very local electromagnetic stimulation fields are required.

An example for use of it is for deep penetration into the brain by so called repetitive Transcranial Magnetic Stimulation or in short rTMS, also called Deep TMS.

Various neurological disorders, including Depression
AlzheimerParkinson's disease, and Migraine are effectively treated by application of this coil type because this technology allows for deep penetration into the brain when placing a butterfly coil directly to the head.

This picture shows that the maximum peak intensity is perpendicular to the center of the butterfly coil and as such has superior ability [compared to a regular PEMF coil] for reaching the locations deep inside the head or body.
Butterfly pemf coil
Butterfly pemf coil on head
Butterfly coil pemf field distribution
PEMF configuration butterfly coil
Butterfly coil intensity plot pemf field
The PEMF intensity is clearly shown in this actual electromagnetic intensity distribution plot.

The peak value for this butterfly coil is 160 milli Tesla
(= 1600 Gauss) measured directly at the center of the coil surface. The further away from the coil => the field intensity decreases.
When measured at a distance of one inch (2.5 cm) from the coil surface the field intensity is now 50 milli Tesla (= 500 Gauss) and at a distance of 2" (5 cm) we still measure a field intensity of 30 milli Tesla (= 300 Gauss) and at a distance of 3" (7.5 cm) the value still exceeds 10 milli Tesla (= 100 Gauss)!

These values show that deep concentrated bone and cell penetration with pulsed electromagnetic fields is indeed possible.

There is evidence that this technology can reduce chronic pain and change pain-related brain and nerve activity. The high intensity in combination with the focused PEMF can be applied very locally to obtain fast pain relief.

The type of copper wire and geometry of the coil configuration, together with the biophysical characteristics of the PEMF pulses, determine the form and the intensity of the magnetic field of the coil.

When generating very high intensity in coils for continuous use with a high power generator, temperature inside the coil increases substantially because of the strong electrical currents fed into the copper wires of the coil. This makes continuous application of butterfly coils for pain relief very difficult, if not impossible.

Solid core coil design results in a more efficient transfer of electrical energy into a magnetic field with a substantially reduced amount of energy dissipated as heat. However, if used continuously the coil still accumulates heat over time, requiring cooling and making it unsuitable for practical applications.

However an open air PEMF coil can however be used for extensive periods of time without substantial temperature increase and can also be used for local pain relief.

What is the Big Idea?
Eating meat or fish can make a crab out of you, according to a study published by Nutrition Journal.
Omnivorous diets are high in arachidonic acid (AA) which changes the brain in a way that affects mood. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), fats prevalent in fish, are suppose to combat the negative effects of AA. However, the study reported significantly worse moods in fish eaters than vegetarians despite higher intakes of EPA and DHA. This is the first study to examine the impact of a meat and fish diet on an omnivore's mood.
Thirty nine meat-eating participants were assigned to one of three diets. A control group ate meat, fish or poultry daily. A second group ate fish 3-4 times weekly but no meat. A third group ate strictly vegetarian. After two weeks, participants completed a questionnaire to assess their moods. The vegetarian group reduced their EPA, DHA and AA intake and the fish eaters increased their EPA and DHA intakes. The mood were unchanged for the omnivores and fish eaters but the vegetarians showed higher mood scores after two weeks.
What is the Significance?
"Reducing meat, fish, and poultry may improve some domains of short-term mood state in modern omnivores," the report concludes. "Exploring this phenomenon further is warranted, as reductions in dietary meat, fish, and poultry would not only reduce health risks but could benefit the environment as well."
Marion Nestle, nutritionist and NYU professor, argues that a vegetarian diet is indeed healthier. But small amounts of meat doesn't hurt. And in developing countries, "where kids don't have enough food, a little meat thrown in makes a big nutritional difference."

Technical Paper / _URL_.13182/NSE11-55
The Gaerttner Laboratory electron linear accelerator at Rensselaer Polytechnic Institute was used in the measurement of the neutron total cross section of natural beryllium and carbon (graphite) in the energy range of 0.4 to 20 MeV. Neutron transmission measurements were made using the time-of-flight method with a 100-m flight path, fast detector response and electronics, and a narrow neutron pulse width to provide good energy resolution. A method was developed to determine the time-dependent background component associated with the transmission measurement using a combination of experimental data and Monte Carlo methods. The signal-to-background ratio combined with low counting statistics error resulted in low uncertainties and highly accurate data. The graphite measurement, showing excellent agreement with the current evaluations, provided a verification of the accuracy in the measurement and analytical methods used. The measurements of beryllium resulted in an accurate measurement of total cross section, showing some deviations with commonly used evaluations and better agreement with ENDF/B-VI.8. These results can be used for the improvement of future neutron cross-section evaluations of beryllium.


\hbox{-}}\)adic cohomology: let
Define the étale \({\mathsf{K}}{\hbox{-}}\)theory of \(A\) as \begin{align*} {\mathsf{K}}^\text{ét}(A)_{\widehat{\ell}} \mathrel{\vcenter{:}}=\mathop{\mathrm{hocolim}}_{n\geq 0} L_{{\operatorname{KU}}} {\mathsf{K}}(A; {\mathbb{Z}}/\ell^n) .\end{align*} Define \begin{align*} \begin{cases} H_{\text{even}, \ell}(A) & \pi_0 {\mathsf{K}}^\text{ét}( (A\otimes_K \mkern 1.5mu\overline{\mkern-1.5muK\mkern-1.5mu}\mkern 1.5mu)_{\widehat{\ell}} ) \otimes_{\mathbb{Z}}{\mathbb{Z}}{ \left[ { \scriptstyle \frac{1}{\ell} } \right] } \\ H_{\text{odd}, \ell}(A) & \pi_1 {\mathsf{K}}^\text{ét}( (A\otimes_K \mkern 1.5mu\overline{\mkern-1.5muK\mkern-1.5mu}\mkern 1.5mu)_{\widehat{\ell}} ) \otimes_{\mathbb{Z}}{\mathbb{Z}}{ \left[ { \scriptstyle \frac{1}{\ell} } \right] }. \end{cases} \end{align*} These are \({ {\mathbb{Q}}_\ell }{\hbox{-}}\)linear \(G_{K}{\hbox{-}}\)modules, and can be used to define NC \(L{\hbox{-}}\)functions.
Let \(K\) be a global field, \(A\) a NC geometric \(K{\hbox{-}}\)scheme. Define \begin{align*} L_\text{even}(A, s) \mathrel{\vcenter{:}}=\prod_{v\in \Sigma_K} L_{\text{even}, v}(A; s) \\ L_{\text{even}, v}(A; s) = {1 \over \operatorname{det}\qty{ \operatorname{id}- N_v^{-s} (\pi_v \otimes{\mathbb{C}}) \mathrel{\Big|} H_{\text{even}, \ell_v} (A\otimes_K K_v)^I_V \otimes{\mathbb{C}} } } ,\end{align*} and \(L_{\text{odd}, v}\) similarly.
\(L_{\text{even}}(A; s)\) is a meromorphic function on \(\Re(s) > 1/2\), and odd for \(\Re(s) > 3/2\).
The even zeros in the critical strip are on \(\Re(s) = {1\over 2}\), and the odd ones on \(\Re(s) = 1\).
Let \(X\) be a smooth proper \(K{\hbox{-}}\)scheme. Then \(R_\text{even}(\mathsf{Perf}_{\mathsf{dg}}(X)) \iff \left\{{R_w(X)}\right\}_{w \text{ even}}\), and similarly for odd, where \(R\) denotes the various forms of GRH.
5.3 Applications to commutative geometry
Let \(K\) be a global field with \(\operatorname{ch}(K) = 0\) and let \(X, Y\) be smooth proper \(K{\hbox{-}}\)schemes and assume condition (C2). Suppose \(\mathsf{Perf}(X) \cong \mathsf{Perf}(Y)\) is a Fourier-Mukai equivalence, then \(\left\{{R_w(X)}\right\}_w \iff \left\{{R_w(Y)}\right\}_{w}\). So this version of GRH is invariant under derived equivalence.
Suppose \(X\) is homologically projectively dual (HPD) to \(Y\), with \(X\to {\mathbb{P}}(V)\) and \(Y\to {\mathbb{P}}(V {}^{ \vee })\). For \(L \subseteq V {}^{ \vee }\), write \(X_L \mathrel{\vcenter{:}}= X{ \underset{\scriptscriptstyle {{\mathbb{P}}(V)} }{\times} } {\mathbb{P}}(L^\perp)\) and \(Y_L = Y{ \underset{\scriptscriptstyle {{\mathbb{P}}(V {}^{ \vee })} }{\times} } {\mathbb{P}}(L)\).
See
Let \(V_1 \cdots V_n\) be simple \(A/J{\hbox{-}}\)modules and consider \(\mathop{\mathrm{End}}(V_i)\) which are division \(K{\hbox{-}}\)algebras. Then \(K \hookrightarrow K_i \hookrightarrow\mathop{\mathrm{End}}(V_i)\) where the \(K_i\) are finite separable extensions, and \begin{align*} \left\{{R_0(\operatorname{Spec}K_i)}\right\}_{1\leq i\leq m} \implies R_\text{even}(A) .\end{align*}
This doesn't exactly help prove GRH, but does help establish properties of various conjectures. See paper of Thomason for paper on étale \({\mathsf{K}}{\hbox{-}}\)theory.

What does breathability mean in a mattress?
Does it count to consider the breathability feature in a mattress?
If these are your question, let us first start with what breathability means. It is the feature that determines how well the air is circulated through the fabric. Therefore, if the mattress is breathable, it will remain cool and satisfying even when sleeping for long hours during hot sunny days. In short, breathability directly impacts your experience regarding health, comfort, and performance as a whole.
In addition, it also controls how many years the mattress will be able to serve you by mitigating wear and tear due to moisture and heat. As a result, enhancing the product's durability and reducing the mattresses vulnerability to an environmental factor.
Check Out: Ways You Can Make Your Mattress Last Longer
How Long Does a Mattress Last in generally?
If the breathability property is top-notch, nothing can hold it back to serve you for at least 7-10 years. However, speaking health and hygiene wise one should replace their mattress every 6 to 8 years.
The life of your mattress will also depend on other factors like how much weight it is carrying, how often you nap on it, the type of mattress you have chosen to install, etc.
Factors Influencing Mattress Lifespan
Like we have discussed, numerous factors determine the lifespan of your mattress. However, to follow a general thumb rule, watch out for the following factors:
The material of which the mattress is made has a substantial impact on how long a mattress last. For example, high-density polyfoam material last longer compared to low-density polyfoam.
2. Mattress Type
- How Long Does A Spring Mattress Last?
The average lifespan of the innerspring mattress is 5 to 6 years. As you shop for the particular mattress, you will find most of them contains pocketed coil allowing all the other coil to work independently. However, mattresses containing traditional coil system works together and counteracts each other's motion. Thus, to determine the durability, there are few points to consider:
- Coil gauge: Mattress containing coil gauge of fourteen or higher are firm while those below are soft. You will be tempted to buy the softer ones, but since they are thin, they have less durability.
- Pillow top: Also, look for pillow top features when determining durability. They add softness to the higher coil gauge.
- Mattress topper: If you purchase a quality mattress topper, it reduces the direct compression, increasing the mattress's lifespan.
- How Long Does A Foam Mattress Last?
A foam mattress usually lasts longer than eight years. However, it may vary depending on the foam it is made of:
- Polyurethane: It is the least expensive mattress you will find; however often compromises on durability. So, before buying, check the density it offers. The higher will be the density, the longer it will last.
- Reflex foam: Their durability is generally higher than the standard foam but is careful of their specification and sagging period.
- Convoluted: Convoluted foam is not well in durability. Though they provide the best kind of support, they are generally short-lived.
- How Long Does A Memory Foam Mattress Last?
The durability of memory foam mattresses is considerably high (6-7 years). However, the body weight you intend to apply and the product's density must be in accordance. If thinking of putting heavy pressure, the density should not be less than five lbs/ft3.
- How Long Does A Latex Mattress Last?
When considering a latex mattress, it lasts for 7 to 8 years. However, it will mainly depend on the blend the product has used in its mattress:
- Natural or synthetic: The product is made from two material types natural and synthetic. Generally, natural are more durable and give higher performance than synthetic ones.
- Replaceable layers: The comfortable layer is added to the mattress to install features like heat transfer, motion isolation, and bounciness. However, it slightly impacts the durability of the product by degrading its quality.
- How Long Does A Coir Mattress Last?
You can expect a coir mattress to last up to 3 to 5 years, after which they tend to sag and disorient. The main reason for this is that it is made from 100% natural coconut fibre, which often becomes vulnerable to environmental factors.
- How Long Does A Hybrid Mattress Last?
Since hybrid mattress is the combination of two or more mattresses, you will have to access the following points to access its durability:
- Density: As said earlier, it is a significant factor determining the product's durability, so it should be enough to carry an average person's weight and higher.
- Warranty: Another way to understand the product's durability is by looking at its warranty period. It should not be less than ten years.
3. Sagging Potential
It is general for the mattress to sag up, especially in areas where you place the heaviest part of your body, like hips and shoulders. This further leads to body pain and dis-alignment if the mattress is not replaced.
Check Out: How To Fix A Saggy Mattress?
4. Body Impressions Potential
Body impressions are a common factor influencing mattress durability. Because of this factor, you can see a semi-permanent print of your body on the mattress generally caused by sleeping in one position.
5. Premature softening potential
Every mattress softens after few regular uses. It is not a problem until it is normal softening. However, when it turns excessively soft, it sags up and affects the comfort and pressure-releasing ability of the bed.
6. Mechanical malfunction potential
This issue is mainly seen in smart beds, airbeds and other mattresses. When this factor gets affected, it impacts manual and remote control, air pumps and outlet connectivity.
7. Mattress Care
Like anything, when you take care of the mattress, it is expected to last longer. One way of increasing longevity is flipping the mattress every six months, given it is two-sided.
8. Mattress Warranty
Warranty offered by companies protect your mattress from early deterioration and saves you from incurring heavy maintenance charges. A standard warranty period extends to 10 years but always try to look for more for better durability.
When to replace a mattress?
Few signs that show it is time to replace your beloved mattress are:
- Other's bed whether at a hotel or a friend's home, seem more comfortable to you
- There is a sense of irritability or achiness when sleeping on your mattress
- Your mattress has gone some sagging and indentations
- The mattress has served you longer than 6-8 years
After gaining the above knowledge, it will be easy to determine the best mattress for yourself. Also, it will save you from developing any pain or disease from sleeping on a bad mattress. However, remember to change it after every six years for best performance.

You're Not Nuts, Squirrels Are Extra Fat This Year
If squirrels have seemed a bit chunkier this winter, it's probably because they actually are.
The reason for the recent thickening is simple. According to experts in North Americaand Britain, unseasonably warm weather has given squirrels in both regions more time to find food, leading to localized populations of double-wide nut hunters in cities like Toronto and Cardiff.
"We have had a really warm November," David Sugarman of the Ontario Science Centre told Metro Toronto. "Naturally, if you're an animal that's got to make it through the winter with little or no food, you want to pack in as much as fat as possible."
In the United Kingdom, last month wasn't just the warmest December on record but also the wettest, resulting in increased production of squirrel favorites like acorns.
"It's been a very odd, unusual year," naturalist Iolo Williams told the BBC. "Squirrels will eat anything, they are omnivores, so I would imagine [non-native] grey squirrels unfortunately will do very well this winter."
Luckily, squirrels self-regulate their body weight and this year's extra ounces are unlikely to have any lasting health effects.
"If the squirrel were able to stay chubby all year round, it might decrease its longevity," said Sugarman. "But eventually the snow is going to come, the cold weather will increase and they're going to burn off some of that extra fat."
In the Southern United States, however, this winter has actually been colder than usual due to El Niño. So if southern squirrel watchers spot an impressively pudgy specimen, it's probably just because everything's bigger in Texas.


An Odd Boston Common Monument
Usually, in public places, especially those with a lot of history, monuments often commemorate an important person or event: the Lincoln Memorial, various war memorials, and so on. The Boston Common is no different, with several large memorials featured prominently. And then there's this odd looking gravestone-like monument just kinda off to the side of the Common (nearest to Beacon Street), which I had never noticed until a couple of weeks ago:
What this all about? Well:
Using the Google, we learn the following about the Oneida Football Club of Boston:
The Oneida Football Club, founded in Boston, Massachusetts in 1862, was the first organized team to play any kind of football in the United States. The game played by the club, known as the "Boston game", was an informal local variant that predated the codification of rules for soccer, rugby, or American football. The team, which consisted of graduates of Boston's elite preparatory schools, played on Boston Common from 1862–1865, during which time they reportedly never lost a game or even gave up a single point.
Thousands of years from now, archaeologists are going to go nuts trying to figure out the significance of this.

New Detailed Understanding of the Mechanism of Radiation in Interconnect Problems
Electromagnetic radiations from parasitic structures such as electronic interconnections are very difficult to diagnose because the ability to identify the specific sources are missing. Mainly, the source of radiations cannot be identified separately. Here, the partial element equivalent circuit (PEEC) method is extended to diagnose the radiation and its distribution. For the first time we identify the individual sources of radiation and the equivalence circuits for the sources. The proposed approach can be applied to find the radiation for electromagnetic interference (EMI) from a wide variety of structures.

and Triangles exercises with the math group. They're still having trouble accepting the sqrt(2) as just another number and not something to be solved. I'm hoping to help them understand it better next week by having them measure triangles and comparing the calculated hypotenuses (hypotenusae?) with the measured values. The computer group started Monday. 4 students, one of whom was absent on Monday. Looks like we shall be using python as none of them have extensive programming experience. I walked through some simple control logic with them, and they appeared to understand the python statements without much explanation. I provided them with a simple program (one explicit function) to look at through the week and to try running (all of them have computers at home). Words I started reading Imagining Numbers (ISBN: _PHONE_) after reading a review on slashdot. I haven't reached a part about imagining i, but my hope is that there will examples I can relay to the math group---if not about i itself, then perhaps irrational numbers in general. Futzing I removed the style sheet information for this into a separate file. Using Dave Raggett's Adding a touch of style, I made some more style changes such as the section backgrounds and creating a footer division which allows me to remove the hr tag. There's very little HTML left in this document now, and for some reason I feel rather pleased. Wed, 26 Mar 2003 21:15:00 UT 2003.03.18 Activity Tomorrow's math group will focus on exponents, roots, and the Pythagorean formula. The exercise sheet is here. Wed, 26 Mar 2003 21:13:00 UT 2003.03.16 Music I flipped by VH1 just as the Police were being inducted. I sat through Roxanne hoping they would follow it with something interesting. Instead, there's a commercial and they start playing Every Breath You Take. That's when the television went off. Futzing I considered writing some code to manage both the html and the rss information. I figured since rss is xml that one of the first things I should do is validate the resulting rss file. It appears that there's no official schema/document type definition for rss 2.0. the mailing list archives would indicate that there's not going to be one either; there are arbitrary rss validators so that might be sufficient.

This only feeds my book purchasing problem. As it turned out, I managed to buy my freedom with just two books (the latest Doonesbury and Fox Trot collections of all things). I considered getting a couple computer books (xml-rpc and python. Fortunately for me, however, I encountered my usual resistance to purchasing programming language/spec books: the belief that most of what I need to know is already documented on the net (or as part of the software itself).

I've been doing yoga (daily when possible). Last night I did the fully-modified workout sufficiently easily that I'll try the 1/2-modified tomorrow. I really enjoy this DVD. It makes use of the DVD multiple-angle feature to provide 4 different workout levels: normal, 1/4-modified, 1/2-modified, and fully-modified. Since my hamstrings are rather inflexible, I've been using the fully-modified angle. GAIAM seems to be the Starbucks of yoga. The DVD I purchased a year or so ago is a Living Arts DVD but their web site now shows it as a GAIAM product. Other GAIAM products area Living Arts co-branded. I wonder when GAIAM purchased Living Arts. There is no mention of it in their press releases. Thu, 13 Mar 2003 03:09:00 UT

US plan for biggest EVER spaceship Fusion II that could reach Jupiter in just 200 days revealed in secret Pentagon docs
A US PLAN for the largest space ship ever built that would be able to transport humans to Jupiter and back have been revealed in Pentagon files obtained by The Sun.
The documents involving deep space exploration and colonisation were released by the Defense Intelligence Agency (DIA) – the Department of Defense's spy arm – after a four-year-long Freedom of Information battle.
They form part of 1,574 pages of real-life X-Files related to the Pentagon's secretive UFO programme, obtained by The Sun under the Freedom of Information Act.
One of the files includes plans and pictures a spacecraft dubbed, Fusion Ship II.
It shows schematics for a massively long and thin craft constructed around a small capsule and a series of reactor arrays.
The deep space craft which is propelled by IEC fusion, an experimental technology which uses electric fields to propel a ship forward.

The plans describe how the space ship will be 300 metres long – almost three times bigger than the Saturn V rocket that took man to the Moon and nearly six time bigger than the Space Shuttle.
However, the craft would only a weigh a maximum of 500 metric tons – much lighter than previous spacecraft.
The proposed design would be able to take 10 astronauts to Jupiter with the trip taking 210 days there and 153 days back.
And that timescale would mean it could hit average speeds of up to 148,852mph – ten times faster than the top speed of the Saturn V rocket which took man to the Moon.

The crew would be housed in a 12m diameter chamber which could be used for both sleep and exercise.
The spaceship will be one of largest ever made which will weigh only a quarter of that of the 2,000 ton Space Shuttle, according to the documents.
Speed would be key as one of the biggest challenges of space travel is the sheer time it takes to traverse the void.
Probes travellingto the gas giant Jupiter – which is between 365 and 601million miles from Earth -andhave previously had to travel for years.
Such long travel periods make manned space flight difficult – whilea ship travelling at speeds of Fusion II would make things much simpler.
"Human factors have not been fully evaluated in this design, but are thought to be acceptable with the short mission time achieved.
LARGEST MANMADE CRAFT
"Fusion Ship II would be one of the largest propelled vehicles ever built, although its mass would be a quarter of that of the Space Shuttle at liftoff."
The Fusion Ship II plans are included in a scientific report called Inertial Electrostatic Confinement Fusion, which was carried out for the DIA by contractor Bigelow Aerospace.
They form part of a huge haul of documents related to the secretive UFO programme – the Advanced Aviation Threat Identification Program (AATIP) – requested by The Sun in 2017.
The DIA finally handed over the bombshell files to The Sun this month, which also include reports on how to communicate with aliens and studies into invisibility.
The bombshell Freedom of Information haul includes reports on the DIA's research into the health impacts of UFO sightings on humans – including burns, heart problems, sleep disturbances – and even bizarre occurrences such as "apparent abduction" and "unaccounted for pregnancy".
AATIP was a secretive Pentagon programme that ran between 2007 and 2012 to study UFOs.
It was outed by whistleblower Luis Elizondo, who headed up the programme, back in 2017.

In visual perception, change blindness is the phenomenon that occurs when a person viewing a visual scene apparently fails to detect large changes in the scene. For change blindness to occur, the change in the scene typically has to coincide with some visual disruption such as a saccade (eye movement) or a brief obscuration of the observed scene or image. When looking at still images, a viewer can experience change blindness if part of the image changes.

NATURAL VENTILATION FOR FALLOUT SHELTERS.
PENNSYLVANIA STATE UNIV UNIVERSITY PARK
Pagination or Media Count:
Two identical eight-story dormitory buildings on the campus of The Pennsylvania State University were used for investigating natural ventilation effects. Equipment for measuring air change rates, consisting of an electronegative gas detector, a system of plastic pipe, a collection and valve control device, and necessary recording instruments, was used to gather data. Results are reported on ventilation of a closed, unoccupied building, and on ventilation of shelters in the basement and on the fifth floor with simulated occupants. Using a tracer gas technique, a series of tests were run to determine the rates of natural and forced ventilation in upper story shelter spaces. Evaluation of portable package ventilation units used in the tests is included and problems which were encountered are reported upon. Author

How to convert from Flutter to Ionic + Angular
Converting from Flutter to Ionic + Angular can appear daunting at first, but with a systematic approach, it becomes manageable. Below, we will delve into the key steps and considerations, optimized for those proficient in Flutter but not as experienced with Ionic and Angular.
Understanding the Differences Between Flutter and Ionic + Angular
Before diving into the technical aspects, it's essential to understand the fundamental differences between Flutter and Ionic + Angular:
 - Framework: Flutter is a UI toolkit based on the Dart programming language. On the other hand, Ionic is a hybrid framework using HTML, CSS, and Angular for mobile and web apps.
 - Components: Flutter uses its own custom widgets, while Ionic uses standard web technologies along with customizable components.
 - State Management: Flutter often utilizes systems like Provider or Bloc, whereas Angular applications leverage RxJS and services.
Setting Up the Ionic + Angular Project
The first step in conversion is to set up a new Ionic + Angular project. You need to have Node.js and npm installed on your system to proceed.
npm install -g @ionic/cli
ionic start myApp blank --type=angular
cd myApp
Migrating UI Components
In Flutter, UI components are primarily created using widgets. In Ionic + Angular, we rely on HTML templates and Angular components.
Converting Flutter Widgets to Ionic Components
Consider a simple Flutter widget:
class MyWidget extends StatelessWidget {
 @override
 Widget build(BuildContext context) {
 return Container(
 color: Colors.blue,
 child: Text('Hello Flutter'),
 );
 }
}
The equivalent in Ionic + Angular would be:
<ion-content>

 Hello Ionic + Angular

</ion-content>
This HTML structure utilizes Ionic's ion-content which is akin to Flutter's Container.
Handling Navigation
Flutter uses a Navigator for route management, whereas Ionic + Angular use Angular Router for navigation.
Converting Flutter Navigator Routes
Example Flutter code:
Navigator.push(
 context,
 MaterialPageRoute(builder: (context) => SecondScreen()),
);
Equivalent code in Ionic + Angular:
First, define your routes in app-routing.module.ts:
const routes: Routes = [
 {
 path: '',
 component: HomePage
 },
 {
 path: 'second-screen',
 component: SecondScreenComponent
 }
];
Next, navigate programmatically with Angular Router:
import { Router } from '@angular/router';
constructor(private router: Router) {}
this.router.navigate(['/second-screen']);
State Management Conversion
In Flutter, state management can vary widely (e.g., using setState, Provider, or Bloc). In Angular, state is often managed using services and RxJS for reactive programming.
Converting a Simple State Management
Consider this Flutter code to increase a counter:
class _MyHomePageState extends State<MyHomePage> {
 int _counter = 0;
 void _incrementCounter() {
 setState(() {
 _counter++;
 });
 }
 @override
 Widget build(BuildContext context) {
 return Scaffold(
 appBar: AppBar(
 title: Text("Flutter Counter"),
 ),
 body: Center(
 child: Column(
 mainAxisAlignment: MainAxisAlignment.center,
 children: <Widget>[
 Text("$_counter", style: Theme.of(context).textTheme.headline4)
 ],
 ),
 ),
 floatingActionButton: FloatingActionButton(
 onPressed: _incrementCounter,
 tooltip: "Increment",
 child: Icon(Icons.add),
 ),
 );
 }
}
Equivalent Angular code would look like this:
Create a service counter.service.ts:
import { BehaviorSubject } from 'rxjs';
export class CounterService {
 private counter = new BehaviorSubject(0);
 currentCounter = this.counter.asObservable();
 incrementCounter() {
 this.counter.next(this.counter.value + 1);
 }
}
Use the service in the component:
import { Component } from '@angular/core';
import { CounterService } from './counter.service';
@Component({
 selector: 'app-home',
 template: '
 <ion-header>
 <ion-toolbar>
 <ion-title>Ionic Counter</ion-title>
 </ion-toolbar>
 </ion-header>
 <ion-content>

{{ counter }}

 <ion-fab>
 <ion-fab-button (click)="increment()">
 <ion-icon name="add"></ion-icon>
 </ion-fab-button>
 </ion-fab>

 </ion-content>
 '
})
export class HomePage {
 counter: number;
 constructor(private counterService: CounterService) {
 this.counterService.currentCounter.subscribe(
 counter => this.counter = counter
 );
 }
 increment() {
 this.counterService.incrementCounter();
 }
}
Conclusion
Converting from Flutter to Ionic + Angular involves a series of straightforward but detailed steps. By understanding the components, navigation, and state management practices in both frameworks, you can adeptly migrate your existing Flutter application into an Ionic + Angular project. While the tools and syntax may differ, the underlying principles of building reactive, user-friendly applications remain consistent.

nftables is a netfilter project that aims to replace the existing ip-, ip6-, arp-, and ebtables framework. It provides a new packet filtering framework, a new user-space utility (nft), and a compatibility layer for ip- and ip6tables. It uses the existing hooks, connection tracking system, user-space queueing component, and logging subsystem of netfilter.
The first release is available in Linux 3.13, which is currently in the [testing] repository (linux), and nftables (the user-space components) is available in the [community-testing] repository (nftables), and on the AUR in package nftables-gitAUR.
Tango-view-fullscreen.pngThis article or section needs expansion.Tango-view-fullscreen.png
Reason: nftables is an entirely new utility, and lacks sufficient documentation on this wiki, as well as elsewhere. (Discuss in Talk:Nftables#)
Overview
nftables consists of three main components: a kernel implementation, the libnl netlink communication and the nftables user-space front-end. The kernel provides a netlink configuration interface, as well as run-time rule-set evaluation using a small classification language interpreter. libnl contains the low-level functions for communicating with the kernel; the nftables front-end is what the user interacts with.
nft
nftables' user-space utility nft now performs most of the rule-set evaluation before handing rule-sets to the kernel. Because of this, nftables provides no default tables or chains; although, a user can emulate an iptables-like setup.
It works in a fashion similar to ifconfig or iproute2. The commands are a long, structured sequence rather than using argument switches like in iptables. For example:
nft add rule ip6 filter input ip saddr ::1 accept
add is the command. rule is a subcommand of add. ip6 is an argument of rule, telling it to use the ip6 family. filter and input are arguments of rule specifying the table and chain to use, respectively. The rest that follows is a rule definition, which includes matches (ip), their parameters (saddr), parameter arguments (::1), and jumps (accept).
The following is an incomplete list of the commands available in nft:
list
 tables [family]
 table [family] <name>
 chain [family] <table> <name>
add
 table [family] <name>
 chain [family] <table> <name> [chain definitions]
 rule [family] <table> <chain> <rule definition>
table [family] <name> (shortcut for 'add table')
insert
 rule [family] <table> <chain> <rule definition>
delete
 table [family] <name>
 chain [family] <table> <name>
 rule [family] <table> <handle>
flush
 table [family] <name>
 chain [family] <table> <name>
family is optional, but it will default to ip.
Tables
The purpose of tables is to hold chains. Unlike tables in iptables, there are no built-in tables in nftables. Tables can have one of four families specified, which unifies the various iptables utilities into one:
 - ip (iptables)
 - ip6 (ip6tables)
 - arp (arptables)
 - bridge (ebtables)
ip is the default family. A fifth family is scheduled for Linux 3.15 that allows for the unification of the ip and ip6 families to make defining rules for both easier.
Listing
You can list the current tables in a family with the nft list command.
# nft list tables
# nft list tables ip6
You can list a full table definition by specifying a table name:
# nft list table foo
# nft list table ip6 foo
Creation
Tables can be added via two commands — one just being a shortcut for the other. Here is an example of how to add an ip table called foo and an ip6 table called foo:
# nft add table foo
# nft table ip6 foo
You can have two tables with the same name as long as they are in different families.
Deletion
Tables can only be deleted if there are no chains in them.
# nft delete table foo
# nft delete table ip6 foo
Chains
The purpose of chains is to hold rules. Unlike chains in iptables, there are no built-in chains in nftables. This means that if no chain uses any types or hooks in the netfilter framework, packets that would flow through those chains will not be touched by nftables, unlike iptables.
Listing
You can list the current chains in a chain with the nft list command, using the same method as listing a table. You can also list rules from an individual chain.
# nft list chain foo bar
# nft list chain ip6 foo bar
These commands will list the bar chains in the ip and ip6 foo tables.
Creation
Chains can be added when a table is created in a file definition or one at time via the nfc add chain command.
# nft add chain foo bar
# nft add chain ip6 foo bar
These commands will add a chain called bar to the ip and ip6 foo tables.
Properties
Because nftables has no built-in chains, it allows chains to access certain features of the netfilter framework.
# nft add chain filter input { type filter hook input priority 0; }
This command tells nftables to add a chain called input to the filter table and defines its type, hook, and priority. These properties essentially replace the built-in tables and chains in iptables.
Types
There are three types a chain can have and they correspond to the tables used in iptables:
 - filter
 - nat
 - route (mangle)
Hooks
There are five hooks a chain can use and they correspond to the chains used in iptables:
 - input
 - output
 - forward
 - prerouting
 - postrouting
Priorities
Note: Priorities do not currently appear to have any effect on which chain sees packets first.
Note: Since the priority seems to be an unsigned integer, negative priorities will be converted into very high priorities.
Priorities tell nftables which chains packets should pass through first. They are integers, and the higher the integer, the higher the priority.
Deletion
Chains can only be deleted if there are no rules in them.
# nft delete chain foo bar
# nft delete chain ip6 foo bar
These commands delete the bar chains from the ip and ip6 foo tables.
Rules
The purpose of rules is to identify packets (match) and carry out tasks (jump). Like in iptables, there are various matches and jumps available, though not all of them are feature-complete in nftables.
Listing
You can list the current rules in a table with the nft list command, using the same method as listing a table. You can also list rules from an individual chain.
# nft list chain foo bar
# nft list chain ip6 foo bar
These commands will list the rules in the bar chains in the ip and ip6 foo tables.
Creation
Rules can be added when a table is created in a file definition or one at time via the nfc add rule command.
# nft add rule foo bar ip saddr 127.0.0.1 accept
# nft add rule ip6 foo bar ip saddr ::1 accept
These commands will add a rule to the bar chains in the ip and ip6 foo tables that matches an ip packet when its saddr (source

|Water Level Indicator Circuit|
D13 form half-wave rectifiers. The rectified output is filtered using capacitors C1 through C3 respectively. Initially, when water level is below strip L1, the mains supply frequency oscillations are not transferred to diode D1. Thus its output is low and LED1 does not glow. Also, since base voltage of transistor T1 is low, it is in cut-off state and its collector voltage is high, which enables tone generating IC1 (UM66) and alarm is sounded. When water just touches level detector strip L1, the supply frequency oscillations are transferred to diode D1. It rectifies the supply voltage and a positive DC voltage develops across capacitor C1, which lights up LED1. At the same time base voltage for transistor T1 becomes high, which makes it forward biased and its collector voltage falls to near-ground potential. This disables IC1 (UM66) and alarm cannot be sounded. Depending upon quantity of water present in the tank, corresponding level indicating LEDs glow. It thus displays intermediate water levels in the tank in bar-graph style. When water in the tank just touches the highest level detector strip L12, the DC voltage is developed across capacitor C2. This enables tone generating IC1 (UM66) and alarm is again sounded.

where Sv=sievert, Gy=gray, WR
=weighting factor specific
to each type of radiation and tissue.
Radiation weighting factor (WR ):
Effective dose [Sv]:
For x-rays and gamma rays and electrons absorbed by human tissue, WR is 1.
For alpha particles it is 20. To compute Sieverts from Grays, simply
multiply by WR. This is obviously a simplification. The radiation weighting
factor WR approximates what otherwise would be very complicated
computations. The values for WR change periodically as new research refines
the approximations.
The probability of a harmful effect from radiation exposure depends on what part or parts of the body are exposed. Some organs are more sensitive to radiation than others.
A tissue weighting factor is used to take this into account. When an equivalent dose to an organ is multiplied by the tissue weighting factor for that organ the result is the
effective dose to that organ. If more than one organ is exposed then the effective dose, is the sum of the effective doses to all exposed organs.

Common Lady's Mantle - Alchemilla vulgaris L. s.l.
Rose family (Rosaceae)
Alchemilla vulgaris is a very diverse group of species with small species that can only be distinguished with difficulty, which is why suffix sl is used (sensu latiore = in the broader sense). The Common Lady's Mantle is widespread throughout the northern hemisphere and in Europe from the Mediterranean to Iceland. It is a 30 to 50cm long half-rosette herbaceous plant, the basal leaves are very characteristic with their rounded, folded blade with 7-9 semicircular flaps. It is reminiscent of a cape as worn by Mary in holy images and since the plant was formerly used in gynaecology, it was named Lady's Mantle. The yellow flowers are very small and are coiled in richly flowering inflorescences. The genus name, Alchemilla (= small alchemist, alchemist herb) probably comes from Arabic (al-Kimiya = chemistry) and refers to the water droplets on the leaf's edge in the early morning emerging from so-called hydathodes through a process of guttation (often erroneously described as "dew"), which then flow together in a funnel-shaped leaf base to form a large pearl. Alchemists have attributed special healing powers to these droplets.
The dried above ground parts consisting of leaves, flowers and stems collected during flowering time are used. The commercial drug comes from farms in eastern and southern European countries.
Lady's Mantle contains tannins (mainly ellagitannins) and flavonoids.
For mild non-specific diarrhea (Commission E).
In combination with other drugs to improve general well-being (traditional use according to § 109a).
Cut drug to prepare tea
Pour 150ml of boiling water over 1 to 2g finely chopped Lady's Mantle herb and then strain after 10 minutes.
A visit to the doctor is recommended after 3 to 4 days of persistent diarrhoea. Currently there is no experience available for its use during pregnancy and breast-feeding as well as for use in children under 12 years old.

Of course..!!This is something not everyone will find themselves acquainted with. But if you make a wild guess for G yielding a geo or gravity, you land safe geek. The g-force associated with an object is its acceleration relative to free-fall. The force measured due to any acceleration other than the acceleration due to gravity is termed as g-force.
G-Force Monitor is a device that measures G-Forces in a moving car. This is a very interesting project. Although such devices are also available commercially, though I say this time and again; but making one on your own saves a lot on the pocket and adds tons on the brains.
It uses PIC 16F877 microcontroller, PIC firmware written in MikroC and software written in Delphi 7. The G-Force is measured using an accelerometer sensor. After much research, the designer had struck to a Three-Axis accelerometer board with ADXL330 sensor produced by Analog Devices. The 3-axis accelerometer board features a small, thin, low power, monolithic IC which measures acceleration with a minimum full-scale range of ±3 g and has 5V voltage level. The microcontroller is connected to IC MAX232 to enjoy a serial connection between the computer and itself. A 9V battery is used for power supply.
In electronics, a firmware is the most basic level software without which a device would be rendered useless. Another crucial thing about this device here is also its firmware. The firmware had been designed in Delphi 7. The user interface of the firmware here is very convenient. It has two graphics; a bigger one for time recording and a smaller one to show last 100 samples. You also have a calculator to make calculations and three real time displays. Besides, there are some conventional functions like New file, Save file, Open file, etc. Some specific buttons include Show Log, Auto Zoom, Swap Charts, Move Zero point and many more. Visit the designer's blog for acute details.

Stitched together into a 3d movie, the viewer gets an overview of nearly the full surface of the moon, and all its craters and mountains. Red colour depicts high areas on the moon, while blue is an indicator for low-lying areas. The movie, that also provides more close-up images, reveals a crater of over 9000 meters deep, and a mountain with a height surpassing 10,000 meters. In addition, the landing sites of a few lunar landers are highlighted. While the video, which you can find after the break, does not provide any new insights, it is interesting to get a detailed view of Earth's only satellite companion.

Bayly Avenue is the only public access into the Karratha Airport, a significant road with high traffic and used by passengers and freight services. Originally constructed in 1984, this 30+ year old road was recently identfied as requiring improvements.
The Bayly Avenue is one of the Corps EnviRoad projects. This project utilised over 30,000 tonnes of locally recycled and repurposed material waste material.
By removing the need for 30,000 tonnes of new and virgin materials, Corps removed the need for transportation vehicles (85 tonne each truck) and their allotted 352
trips – (85 tonne of material per vehicle x 50 kms round trips). These trips would have
consumed over 20,000 litres of fuel and created a significant amount of carbon emissions.
Corps is proud that the City of Karratha supported the decision to invest more sustainable sustainable initiatives and outcomes for the Karratha community.

The Brandenburg-Prussian Superior Board of Mines in Berlin Responsibilities, Tasks and Leading Personalities from 1810 to 1838
The fact that the Brandenburg-Prussian Superior Board of Mines or the Superior Board of Mines for the Provinces of Brandenburg and Prussia only existed for 28 years is probably why this authority has failed to receive the credit it deserved for its work in more recent histories of mining administration. Nevertheless, the establishment of this now virtually forgotten Superior Board of Mines in 1810 can be regarded as a result of the Stein-Hardenberg administrative reforms. To demonstrate this, the article begins with a brief review of the mining laws and the administration of the Prussian mining industry towards the end of the 18th century.
The report then describes in detail what led to the establishment of this provincial authority and how its responsibilities changed over the years from its foundation in 1810 to its dissolution in 1838. A close look is also taken at the Board's staff, in particular the long-standing head of the Board and subsequent Director of Mines, Hans Otto Philipp Martin. Before he took over the management of die Silesian Superior Board of Mines in 1833, he fought in the mid-1820s for the survival of the Brandenburg-Prussian Board, which was already doubtful only 15 years after its establishment. In the end, however, he was unable to prevent the Superior Board of Mines for Brandenburg and Prussia having to hand over its work to the Berlin Superior Mining Directorate and other subordinate authorities. It was finally dissolved in 1838.

The Quality Enhancement Plan (QEP) is the component of the reaffirmation process that reflects and affirms the commitment of SACS to enhance the quality of higher education and focus on student learning. The QEP describes a carefully designed course of action that addresses a well-defined and focused topic or issue related to enhancing student learning. The QEP will be embedded within JMU's ongoing integrated institution-wide planning and evaluation processes. The topic may evolve from the existing process or from others related to the university's internal reaffirmation report and review.
Developing a QEP as part of the reaffirmation process is an opportunity for us to enhance overall institutional quality and effectiveness by focusing on an issue the institution considers a way of improving student learning. The evaluators expect the QEP to present a clear and comprehensive analysis of the selected topic and show its crucial importance to the institution. The QEP is expected to include:
- A university-wide process for identifying key issues
- Broad-based involvement of institutional constituents in the development and implementation
While the Compliance Certification focuses on the present, the QEP looks to the future. Topic selection will begin soon. If you have an idea for how JMU can enhance its student learning, you could be part of the QEP! Go to _URL_ for more information and to submit your proposal.

Discuss RNNs in the context of Bayesian Machine Learning.
Traditional RNNs and Similarity to Bayes Rule In essence, Bayesian means probabilistic. The specific term exists because there are two approaches to probability (bayesian and frequentist). Bayesians think of it as a measure of belief, so that probability is subjective and refers to the future. Specificaly, Bayesians use Bayes' Rule to update a probability based on a predictor prior probability, likelihood, and class prior probability using the sum rule (p(X)=Yp(X,Y)p(X)= \sum_Y p(X, Y)) and product rule (p(X,Y)=p(YX)p(X)p(X, Y) = p(Y | X)p(X)) of probability. Changing probabilities with new updates through time is similar to what RNNs do.
For example, if we want to predict a given category cc of data XX (contains data points x1,....,xnx_1,...., x_n)that will be chosen from a sample next (for example, cc could be one of a variety of words from a dictionary), after already having done nn samples (or having passed through nn words already), we could use Bayes rule as follows:
P(cx))Posterior Probability=P(xc)likelihoodP(c)Class Prior ProbabilityP(x)predictor prior probability\underset{\text{Posterior Probability}}{P(c | x))} = \frac{\overset{\text{likelihood}}{P(x|c)} \overset{\text{Class Prior Probability}}{P(c)}}{\underset{\text{predictor prior probability}}{P(x)}}
p(cX)=p(x1c)×p(x2c)×...×p(xnc)×p(c)p(c | X) = p(x_1 | c) \times p(x_2 | c) \times... \times p(x_n | c) \times p(c)
In short, the way classical RNNs update (and by extension LSTMs and GRUs) is very similar to how Bayes' rule would be applied to time-series data.
Bayesian RNNs
It is also possible to update RNNs through variational Bayes. This is discussed further in a paper out of DeepMind: "Bayesian Recurrent Neural Networks"
Can we do Batch Normalization in RNNs? If not, what is the alternative?
No, you cannot use Batch Normalization on a recurrent neural network, as the statistics are computed per batch, this does not consider the recurrent part of the network. Weights are shared in an RNN, and the activation response for each "recurrent loop" might have completely different statistical properties
Other techniques similar to Batch Normalization that take these limitations into account have been developed, for example Layer Normalization. There are also reparametrizations of the LSTM layer that allow Batch Normalization to be used, for example as described in Recurrent Batch Normalization by Coijmaans et al. 2016.
Some DL frameworks make it seem like you can use batch normalization in RNNs, but these typically involve reparametrized LSTMs and not vanilla recurrent networks (which need modifications or a different form of batch normalization)
What is an Autoencoder? What does it "auto-encode"?
In machine learning, Autoencoding is reducing the dimensions of the dataset while learning how to ignore noise. An Autoencoder is an unsupervised artificial neural network used for learning. Specifically, it learns how to compress data then reconstructing it back to a representation close to the original form.
What were Autoencoders traditionally used for? Why there has been a resurgence of Autoencoders for generative modeling?
Autoencoders were traditionally used for pre-training of Artificial Neural Networks. According to the history provided in Schmidhuber, "Deep learning in neural networks: an overview," Neural Networks (2015), auto-encoders were proposed as a method for unsupervised pre-training in Ballard, "Modular learning in neural networks," Proceedings AAAI (1987). It's not clear if that's the first time auto-encoders were used, however; it's just the first time that they were used for the purpose of pre-training ANNs.
Generative models typicaly fall into either unconditional models (sampling xx from a probability distribution p(x)p(x)) or conditional models (sampling xx from a probability distribution p(xy)p(x | y)). In both cases, being able to generate complex outputs from a learnable function (or learnable latent variables) is extremely useful. Autoencoders are useful for generating these lower-dimensional representations from which diverse-yet-realistic outputs can be obtained.
What is recirculation?
Unlike general feedforward networks, autoencoders may also be trained using recirculation (Hinton and McClelland, 1988), a learning algorithm based on comparing the activations of the network on the original input to the activations on the reconstructed input. Recirculation is regarded as more biologically plausible than back-propagation but is rarely used for machine learning applications. Specific recirculation algorithms vary between some autoencoder types
What loss functions are used for Autoencoders?
Many autoencoders work well with loss functions like the mean squared error loss function. Adding regularization to the loss is useful for giving the autoencoder other properties besides the ability to directly copy its input to its output. Many other regression loss functions also work well with autoencoders.
Cross-entropy and other classification loss functions are generaly poor choices for most autoencoders.
What is a linear autoencoder? Can it be optimal (lowest training reconstruction error)? If yes, under what conditions?
In its simplest form, the autoencoder is a three layers net, i.e. a neural net with one hidden layer. The input and output are the same, and we learn how to reconstruct the input.
Such an architecture can be optimal (i.e., lowest training error for a given hidden layer size) if it has the following properties:
 - Tied Weights
 - Weight Orthognoality
 - Feature non-correlation
 - Unit norm of the weights being 1
What is the difference between Autoencoders and PCA?
PCA is restricted to a linear map, while auto encoders can have nonlinear enoder/decoders.
A single layer auto encoder with linear transfer function is nearly equivalent to PCA, where nearly means that the WW found by an autoencoder and PCA won't be the same—but the subspace spanned by the respective WW's will.
What is the impact of the size of the hidden layer in Autoencoders?
We can an autoencoder very powerful by increasing the size of the hidden layers. Increasing these hyperparameters will let the autoencoder learn more complex codings. But, we should be careful to not make it too powerful, otherwise the autoencoder will simply learn to copy its inputs to the output, without learning any meaningful representation. It will just mimic the identity function. The autoencoder will reconstruct the training data perfectly, but it will be overfitting without being able to generalize to new instances, which is not what we want. This is why we use a "sandwich" architecture with hidden layer sizes smaller than the inputs or outputs (also known as a "bottleneck" architecture).
What is an undercomplete Autoencoder? Why is it typically used for?
An undercomplete autoencoder has no explicit regularization term - we simply train our model according to the reconstruction loss. Thus, our only way to ensure that the model isn't memorizing the input data is the ensure that we've sufficiently restricted the number of nodes in the hidden layer(s). As such, it is typically used in dimensionality reduction cases.
What problems might a nonlinear undercomplete Autoencoder face?
If too much of the input to the undercomplete autoencoder is random noise or irrelevant data, the autoencoder might not be able to learn any meaningful representations of the data.
What are overcomplete Autoencoders? What problems might they face? Does the scenario change for linear overcomplete autoencoders?
In overcomplete autoencoders, where the dimension of the latent representation is greater than the input. In these cases, even a linear encoder and linear decoder can learn to copy the input to the output without learning anything useful about the data distribution.
Discuss the importance of regularization in the context of Autoencoders.
We can regularize the autoencoder by using a sparsity constraint such that only a fraction of the nodes would have nonzero values, called active nodes. In particular, we add a penalty term to the loss function such that only a fraction of the nodes become active. This forces the autoencoder to represent each input as a combination of small number of nodes, and demands it to discover interesting structure in the data. This method works even if the code size is large, since only a small subset of the nodes will be active at any time.
Why does generative autoencoders not require regularization?
The generative section of a generative autoencoder (i.e., the decoder) mimics the process by which the input data was created. Rather than reconstructing input data as closely as possible, the training process forces the generative autoencoder to produce outputs that fit within a distribution of the traning data features. As such, regularization through sparsity constraints is redundant.
What are sparse autoencoders?
A sparse autoencoder is simply an autoencoder whose training criterion involves a sparsity penalty. In most cases, we would construct our loss function by penalizing activations of hidden layers so that only a few nodes are encouraged

'Diffuse' vs. 'Defuse'
What to Know
Diffuse can be used as a verb meaning "to spread out" or an adjective meaning "spread out" or "not concentrated." It is often confused with defuse which can only be a verb originally meaning "to take the fuse off a bomb" but now usually means "to make less dangerous or tense."
Meaning of Diffuse
First off, only one is ever an adjective: diffuse as an adjective most often means "not concentrated or localized," as in "diffuse lighting" or "a diffuse scent." It also means "being at once verbose and ill-organized," as in "a diffuse explanation that failed to provide any information." It comes from a Latin word meaning "to spread out."
It's when we venture into verb territory, though, that things can get muddled. Diffuse the verb comes directly from the adjective: something diffuse can be said to have diffused or been diffused. That is, it has spread out, or has been spread out, both literally and figuratively. Consider the following undeniably difficult situation:
My roommate's incessantly burning incense diffuses throughout the apartment.
My roommate wants the incessantly burning incense to diffuse more evenly throughout the apartment, but I do not.
My hatred for the scent of the incessantly burning incense is fueling a resentment that is diffusing through the relationship like a painful canker.
Sounds like things are getting tense with these roomies. Perhaps there's a way to, ahem, diffuse the situation.
But that, dear friends, is NOT it. One does not diffuse a situation, unless one is spreading it out, which, we assert, is hard to do. No, the word called for in the sentence above is defuse. It's an entirely different word, although it sounds almost identical to diffuse:
Meaning of Defuse
Defuse is a World War II relic, and in its original meaning it is merely a sum of its parts: deand fuse. It means "to remove the fuse from (a mine, a bomb, etc.)." Its figurative meaning developed quickly after, and is now the meaning most of us are most likely to encounter: "to make less harmful, potent, or tense."
While situations are hard to spread, situations can, with a little luck, be made less tense, which is why when it comes to dealing with situations, defuse is your word.
In summary: Diffuse is both a verb and an adjective, and refers to the spreading of something, or making it less concentrated. Defuse functions only as a verb and means "to remove the fuse from something."

SE Healthcare's Stephanie Sargent and Dr. Richard Waldman Contribute Chapter to Obstetrics and Gynecology Clinics of North America
Stephanie Sargent, VP of Product Development and Quality at SE Healthcare, and Dr. Richard Waldman, SE Healthcare Board Member, contributed the chapter The Patient Experience and Safety to Volume 46, Issue 2 of Obstetrics and Gynecology Clinics of North America, June 2019, Pages 199-214.
Obstetrics and Gynecology Clinics of North America is published four times per year. Each issue focuses on a single topic in obstetrics and gynecology. This issue centers around patient safety.
The focus of Sargent and Waldman's chapter is the impact of the patient experience on patient safety and trends that impact patient engagement. In the late 1960s/early 1970s, Dr. Waldman experienced firsthand the medical community's strong opposition to consumer-driven efforts to take more control of the patient experience. Over the following decades, persistent efforts led by patients, thought-leader physicians and agencies such as the Institute of Medicine created the foundation of what is termed "patient-centered care".
Now, the patient experience is not only foundational to quality and safety, it is a business imperative with the continuing shift towards value-based payments models. Sargent and Waldman suggest that the future of patient experience will be grounded in consumerism, transparency and convenience.
Stephanie Sargent, MHA, RN, CPPS, is a seasoned clinical and Lean Six Sigma professional with more than 25 years of experience in healthcare. As a certified Lean Six Sigma Black Belt, she is skilled in identifying clinical and operational performance gaps to decrease professional liability risk, meet regulatory and accreditation requirements, improve clinical quality and patient outcomes and reduce waste and inefficiencies. She previously served as the Patient Safety Program Manager at the Medical University of South Carolina where she directed safety efforts throughout the health system and provided strategic direction and programmatic initiatives to improve patient safety. Stephanie also worked as a registered nurse in Atlanta, Georgia; San Diego, California; and Charleston, South Carolina.
Dr. Richard N. Waldman has been practicing OB-GYN care in the Syracuse area since 1976 and is President of Associates for Women's Medicine, a nine-physician obstetric and gynecological specialty practice. Dr. Waldman, a Diplomat of the American Board of Obstetrics and Gynecology, is the past president of the American College of Obstetricians and Gynecologists (ACOG), a premier private, not-for-profit organization of 56,000 members dedicated to the advancement of women's healthcare through continuing medical education, practice and research. Dr. Waldman is the President of the Medical Staff at St. Joseph's Hospital Health Center in Syracuse, NY and a member of the Board of Trustees.

Generation of Spatially Varying Polarization by Interference with Polarized Light
Interferometry is an important technique for optical metrology. As an example, a Mach-Zehnder interferometer with coherent laser source is build up in VirtualLab Fusion. Particularly in this example, two polarizers are inserted to control the polarization states of the two interfering beams. By rotating one polarizer, the changes in the interference pattern is visualized, and as a result, spatially varying polarization is generated.

Tobacco use dates back over 1300 yrs
Washington, Jan 12 (ANI): Nicotine traces have been discovered in a 1,300-year-old Mayan flask decorated with hieroglyphics that apparently point to the intended contents, researchers say.
A scientist at Rensselaer Polytechnic Institute and an anthropologist from the University at Albany teamed up to use ultra-modern chemical analysis technology at Rensselaer to analyze ancient Mayan pottery for proof of tobacco use in the ancient culture.
Dmitri Zagorevski, director of the Proteomics Core in the Center for Biotechnology and Interdisciplinary Studies (CBIS) at Rensselaer, and Jennifer Loughmiller-Newman, a doctoral candidate at the University at Albany, have discovered the first physical evidence of tobacco in a Mayan container.
The interior of the vessel had not been cleaned, leaving the interior unmodified and the residue protected from contamination.
The approximately two-and-a-half-inch wide and high clay vessel bears Mayan hieroglyphics, reading "the home of his/her tobacco."
The vessel, part of the large Kislak Collection housed at the Library of Congress, was made around 700 A.D. in the region of the Mirador Basin, in Southern Campeche, Mexico, during the Classic Mayan period.
Tobacco use has long been associated with the Mayans, thanks to previously deciphered hieroglyphics and illustrations showing smoking gods and people, but physical evidence of the activity is exceptionally limited, according to the researchers.
Zagorevski used the technology within CBIS at Rensselaer, usually reserved to study modern diseases and proteins, to analyze the contents of the vessel for the chemical fingerprint of tobacco.
The technology included gas chromatography mass spectrometry (GCMS) and high-performance liquid chromatography mass spectrometry (LCMS).
Both are analytical chemistry techniques that combine the physical separation capabilities of gas or liquid chromatography with the analysis capabilities of mass spectrometry. The latter is used to determine molecular weights of compounds, their elemental composition, and structural characteristics.
Zagorevski and Loughmiller-Newman's analysis of the vessel found nicotine, an important component of tobacco in residues scraped from the container.
Both techniques confirmed the presence of nicotine. In addition, three oxidation products of nicotine were also discovered. Nicotine oxidation occurs naturally as the nicotine in tobacco is exposed to air and bacteria.
None of the nicotine byproducts associated with the smoking of tobacco were found in the vessel, indicating that the vessel housed unsmoked tobacco leaves (possibly powered tobacco) and was not used as an ashtray.
No other evidence of nicotine has been found, at this time, in any of the other vessels in the collection.
The study will be published in journal Rapid Communications in Mass Spectrometry. (ANI)
