They can also provide links to their own Web site and tutorials. App authors can provide screenshots and in-depth descriptions on their app page. With these features, we hope to encourage users to browse the App Store, discover and learn about apps, and install them to expand the capabilities of Cytoscape.Īpp pages have several aspects to help users learn about a particular app’s capabilities and usage ( Fig. Third, users can search for an app based on its name, description, categories, authors and authors’ institutions. An app can belong to several categories, each chosen by their authors. Users find all apps of a given type by clicking on a category. Second, there is a list of categories for users with a general idea of the kind of app in which they are interested. Thus, we promote a learning-by-action approach to understanding the role and scope of apps by maintaining a low barrier to entry. First, we provide a Featured Apps section that invites new users of Cytoscape to simply click on a featured app, read about it and, with a single click, install it. The App Store offers multiple ways for users to discover apps ( Fig. Users can rate, review and perform one-click installation from their browser 2 METHODS ( B) A Cytoscape app page, where users can learn about the app through screenshots, a description and tutorial and Web site links. ( A) The Cytoscape App Store main page, with three ways for discovering apps: Featured Apps, Categories and Search. Here, we describe the features of the App Store for both users and app developers. The overarching goals of the Cytoscape App Store are to highlight the important features apps add to Cytoscape, to enable researchers to find apps they need and for developers to promote their apps. 1A) to coincide with the release of Cytoscape 3.0, a major re-architecturing of Cytoscape for improved stability, performance and versatility. To help address the needs of users, we launched the Cytoscape App Store ( Fig. Moreover, when users did find an interesting app through the web page catalog, they had to search for the app again in Cytoscape to install it. This catalog did not make it easy for users to discover apps in which they might be interested, e.g. Each app entry in the catalog listed all versions of an app and did not emphasize the latest version. Search was limited to exact matches to app names users could not search by app description, category or author and apps were categorized by single terms chosen by the Cytoscape team, not app developers. Originally, the Cytoscape team maintained a catalog of submitted apps (called ‘plugins’ at the time) that were accessible from a web page or from within Cytoscape. Over 150 free apps have been contributed to our Web site by developers from over a dozen countries. The wide-ranging functionality and specialization of Cytoscape principally reside in its apps. Cytoscape apps are additional software packages independently developed, licensed and installed. In addition, Cytoscape has an open architecture so that others can extend its functionality with apps. When users first install Cytoscape, it has a small well-defined set of functionality for working with networks. Cytoscape is an open source software tool for network visualization and analysis, primarily for biological data ( Cline et al., 2007 Shannon et al., 2003).

Results show that whereas nanometer-scale tendrils (fuzz) would grow on planar tungsten surfaces, the fuzz formation on micro-engineered surfaces was greatly reduced due to backscattering of ions and the increased surface area. The samples were exposed to helium plasma at 30 - 100 eV ion energy, 823 - 1123 K temperature, and 5 x 10^25 - 2 x 10^26 m^-2 ion fluence. Additionally, two samples with reticulated open-cell foam geometry, one at 45 pores per inch (PPI), and the other at 80 PPI were fabricated with Chemical Vapor Deposition (CVD). These samples included two surfaces covered with uniform micro-pillars one with cylindrical pillars 1 micron in diameter and 25 micron in height, and one with dendritic conical pillars 4 - 10 micron in diameter and 20 micron in height. We investigate here the formation mechanisms of helium bubbles in tungsten that has been micro-engineered utilizing both theory and experiments.Įxperiments on four different micro-engineered surfaces were conducted at the PISCES facility at the University of California, San Diego (UCSD), where they were exposed to various fluences of low-energy helium plasma, with planar surface as control. Helium plasma exposure of tungsten in fusion devices causes extensive damage due to the creation of nanometer-scale subsurface bubbles. Since the penetration of low-energy helium is very shallow, it may be advantageous to manipulate the surface of the solid by micro-engineering techniques so as to provide a degree of control over the resulting plasma-induced damage. Our propulsion system is going to make this future possible and it comes with the complicated name of – 4He Based Closed Cycle Non-combustion Electrical Powered Space Propulsion, let’s break it down:Understanding the interaction mechanisms between low-energy helium plasma and solid materials has significant implications in several advanced technologies primary amongst them are fusion energy and space electric propulsion. It is significantly lighter which allows several times more useful cargo as we don’t burn fuel which is ~85% of the rocket mass.It is safer as doesn’t involve controlled micro explosions and mixing super-hot chemicals.The rockets can run just for a few minutes, our propulsion can run for longer, years longer in-fact.Let’s see why this propulsion will be such a game changer and how it compares with the existing rocket propulsion systems: Propellant-less means that it doesn’t use propellant.Space propulsion means that it is specifically designed for space traveling.4He based means that we are utilizing the super-fluidity phase transition of Helium to release the excessive momentum into space as heat.Electrical powered means that this propulsion system runs purely on electricity and by using nuclear power source it can run for years with no need of refueling.Non-combustion means that we are not burning anything, so it is significantly safer to operate.It is closed cycle meaning that except heat we are not releasing anything into space, no burned fuel, no exhaust, nothing.Our propulsion system is going to make this future possible and it comes with the complicated name of – 4He Based Closed Cycle Non-combustion Electrical Powered Space Propellant-less Propulsion, let’s break it down: The normal rockets can run just for a few minutes, with our propulsion they can run for longer, years longer in-fact with no need of refueling.Ĭan you imagine a future in which the humanity is mining asteroids and you can visit Saturn in matter of weeks? Delivering this project on time is the main focus of the company. The back card is folded into a flattened "U" shape, with the sides being visible along the ends (often referred to as the spine) of the case. In addition, there is usually a back card, 150 by 118 millimetres (5.9 in × 4.6 in), underneath the media tray and visible through the clear back, often listing the track names, studio, copyright data and other information. The liner notes typically will be a 120 by 120 millimetres (4.7 in × 4.7 in) booklet, or a single 242 by 120 millimetres (9.5 in × 4.7 in) leaf folded in half. The front lid contains two, four, or six tabs to keep any liner notes in place. All three parts are made of injection-moulded polystyrene. Two opposing transparent halves are hinged together to form the casing, the back half holding a media tray that grips the disc by its hole. It is a three-piece plastic case, measuring 142 by 125 by 10 millimetres (5.59 in × 4.92 in × 0.39 in), a volume of 177.5 cubic centimetres (10.83 cu in), which usually contains a compact disc along with the liner notes and a back card. For example "Band of Brothers" (see below) is packed in a digipak which is attached to a tin box - this goes under "custom".A jewel CD case is a compact disc case that has been used since the compact disc was first released in 1982. Note that borders are a little blurred here. I'd like to stress once again, cardboard slipcases or sleeves are NOT drawers (see Keep Case, Box Set and Digipak)! Is quite rare as a case type nowadays.Įverything that doesn't fit one of the above descriptions is a custom case. This is a plastic case with a plastic tray that slides out like a drawer. Is quite rare as a case type for DVDs nowadays. But unlike keep cases, which have rounded corners and edges, clamshells have salient edges. Looks like those "fake books" you stored VHS cassettes in back then and thus is quite similar to a thick keep case. The only case type apart from certain custom cases to feature a real hinge-joint for the front cover and not just a fold. Consists out of three parts of hard, usually transparent plastic (front, back and tray) which are snapped together (can be disassembled without damage when you're cautious). Usually comes in a slipcase (again: this is NOT a "drawer").Īlso known as "Super Jewel". Consists out of a folding piece of cardboard featuring cover artwork, with one or more transparent plastic trays attached to it (glued on, can't be disassembled without damage). The case can be disassembled without being damaged.Īlso known as "hub" (in older versions of DVD-Profiler). The plastic tray has a short lid, which snaps shut (hence the name), locking the cover. Is assembled out of a black plastic tray with a piece of cardboard which features the cover artwork attached to it. Once again, this is NOT a "drawer"!Īlso known as "Ivy Hill Snapper" ("Ivy Hill" is the company who makes them). It is most commonly used in box sets.Ī box set consists out of two or more movies or episodes in separate cases (most commonly keep cases, but not always) in a cardboard slipcase. It offers space for up to two discs or one disc and a thin inlay or booklet. The thinner version (about 5mm / 0.2" thick) is often called "Slim case". The thicker version (about 2,5cm / 1" thick) of the keep case, which usually holds more discs (up to seven) is often called "Alpha case" (similar to "Amaray", "Alpha" is a manufacturer who also makes "normal" keep cases, so this terminology isn't necessarily correct). Note: All kinds of keep cases with cardboard slipcases or sleeves (see picture 3 and 4) are NOT the case type "drawer"! Some also have additional freerunning trays hung in on the inside, apart from that all versions of keep cases have one thing in common: They are made out of one single piece of plastic, with a transparent foil on the outside where you slip the actual cover artwork behind. Comes in different colors (black, white, red and transparent are common) and holds one to three DVDs with a multitude of retention mechanisms for the discs. Keep CaseĬommonly known as "Amaray" (actually, "Amaray" is the name of one company who manufactures keep cases). Check contribution notes and/or forum if you're unsure. Always chose the case type of the initial release of the DVD when contributing a profile. Often the initial pressing gets some sort of limited packaging, like a keep case with cardboard sleeve or a digipak, while later pressings come in a generic keep case. When setting a case type, please keep in mind that distributors sometimes change the case of a release. Please also see this thread in the InterVocative forums. This page is supposed to be an assistance when choosing which case type to set when creating a profile with InterVocative Software's DVD Profiler. “Never ask Google for medical advice I have gone from a mild headache to clinically dead in three clicks…”ģ4. “I think the clutch has gone in my butt… Because I can’t get my ass into gear!!”ģ3. “Don’t lose your pen Lose your pen = lost pen Lost pen = nothing on paper Nothing on paper = no grades No grades = failing school Failing school = no college No college = no job No job = no money No money = no food No food = skinny Skinny = ugly Ugly =no love No love = no marriage No marriage = no children No children = alone Alone = sickness Sickness = death!”ģ2. “Girls will be girls” Best Quotes on Minions funny Memes, Funny minion quotes Imagesģ1. “They’re called ‘Man hours’ because a woman would have that shit done in 20 minutes!”Ģ9.

So, I think it would be great if there was a platform that allowed us to view wonderful THETA 360-degree images from all around the world on VR goggles. We don’t often get the chance to see other people’s THETA images with VR goggles. – Spherical Image – RICOH THETAĪn example shot with THETA Z1 actually seen in Oculus Quest 2 Using the Oculus Quest 2 I looked at my own THETA images as well as some that other people took. Is there anything else you’d like to share about your VR experience? * VR goggles should not be used by children under 12 years old. Students may be able to enjoy the lesson more and deepen their understanding of the subject matter. For example, you can incorporate it into hands-on lessons in junior high school such as geography, starry sky observation, biology, and other topics. VR let’s you enter the world in your photos, so I would recommend it to people who are looking for stress relief or healing by viewing beautiful scenery and animals.Īlso, when telling our family or friends about our experiences, it would be easier for them to share our excitement by showing them our photos with VR goggles.Īlso, I think it will be useful in education. I would say it is about the same difficulty as importing photos from a digital camera or smartphone to your PC. It was very easy because I just dragged the THETA files to the Oculus folder after connecting it via USB to my PC. Was it easy to save and view THETA images on Oculus via a PC? I think the beauty of VR is that the moment we put it on, suddenly another world expands before our eyes and we feel as if we’re there. But with VR goggles, I see only the scene in the photo, so I felt like I could actually enter the world in the image. When I’m looking at the photos on a PC or smartphone screen, I can see my surroundings in my field of view, so it’s not as immersive. How was it different from what you can see on your PC or smartphone? I was looking at the scenery I took while traveling, so I looked into the distance in the goggles and unconsciously said, “wow, so beautiful!” I was immediately drawn into and overwhelmed by the world in the video. It looked more three-dimensional than I expected. What was it like seeing THETA images with VR goggles for the first time? We asked the new THETA marketing team member about her experience viewing 360 degree photos on the Oculus Quest 2. What is it like viewing 360-degree images on Oculus Quest 2?

The possibility of trains being fitted with seatbelts was raised and rejected, as it was again 20 years later after the derailment at Ufton Nervet in 2004. The DBSO and third vehicle were so badly damaged that they had to be cut up on site.Ĭasualties were mainly in the two leading vehicles most fatalities were due to passengers being ejected through windows, being hit by other passengers or by objects as the vehicles were thrown about. The third vehicle was hit by the DBSO, as it fell back down the wall of the cutting, after rebounding from the trees. The second vehicle, after climbing over the rear end of the DBSO, somersaulted end over end, eventually hitting the fifth vehicle as it ran past it. It then turned on its side, as it was pushed round by the force of the train behind. The DBSO ran derailed for approximately 100 yards (90 m) and then veered to the left, before running up the edge of the cutting into trees at the top. The impact of the collision destroyed the animal, but a significant part of the carcass, later thought to be a leg bone, became trapped under the leading bogie of the DBSO, lifting it off the track and derailing it. The train hit the cow, an adult Ayrshire weighing 700–1,000 pounds (320–450 kg), at 17:55 ( BST). The dynamics of the train, with the locomotive pushing from behind, meant that when the brakes were applied from the DBSO at the front there was a delay in transmission of the signal to the locomotive brakes to prevent a sudden backlash to the carriages in front this caused the train to decelerate only slightly. After passing the junction the train driver, John Tennant, spotted a cow on the line in the cutting on the approach to Falkirk High and made an emergency brake application he had only between six and twelve seconds to react to the obstruction and apply the emergency brakes because of the curvature of the track. To the west of Polmont, the track curved left and passed the junction for Stirling, then curved right with a steady gradient towards Falkirk High station. 9706) – made a scheduled stop at Linlithgow station and accelerated to approximately 85 mph (137 km/h), passing through Polmont station shortly afterwards. On Monday 30 July 1984, a westbound express train, the 17:30 service from Edinburgh Waverley to Glasgow Queen Street – consisting of a British Rail Class 47/7 diesel-electric locomotive pushing five Mark 3 coaches and fronted by a DBSO (no. An object deflector is fitted to the lower front. Accident Ī DBSO similar to the one involved in the accident. However, it left the front of the train vulnerable when being pushed from behind because the front end was lighter than the rear and had the risk of being pushed over an obstruction, leading to derailment. This system meant that the train could continuously run between the two cities without having to allow time to switch the locomotive to the front of the train between departures. DBSO carriages were introduced on the line in 1980 and consisted of a passenger carriage with a control cab at the front for the driver a DBSO would be situated at the front of the train allowing the driver to control the locomotive with a set of remote controls from which control signals were sent through the lighting circuits of the train to the locomotive pushing from behind. At the other end of the train was a Driving Brake Standard Open (DBSO). At the time of the accident, British Rail passenger trains between Glasgow Queen Street and Edinburgh Waverley were operated by the push-pull technique with a single British Rail Class 47 locomotive located at one end of the train at all times (the locomotive usually pulled the carriages from Glasgow to Edinburgh and pushed them on the return journey). The accident happened on one of the busiest commuter lines in Scotland. The accident led to a debate about the safety of push-pull trains on British Rail. The collision caused all six carriages and the locomotive of the train to derail, killing 13 people and injuring 61 others. A westbound push-pull express train travelling from Edinburgh to Glasgow struck a cow, which had gained access to the track through a damaged fence from a field near Polmont railway station. The Polmont rail accident, also known as the Polmont rail disaster, occurred on 30 July 1984 to the west of Polmont, near Falkirk, in Scotland. The structure is four stories tall and was likely abandoned just 100 years or so after it was built, since it was already in ruins when it was first described by a Jesuit missionary in 1694. If you listen really carefully, you can almost hear the sound of their ancient laughter as they imagine how much time we'd all be wasting on their stupid little pile of rocks.Īccording to the National Park Service, archaeologists still haven't figured out what Casa Grande was actually for. Honestly, maybe it was just a bunch of bored elders hoping to mess with their descendants in a few centuries. The effort to build such a thing would have been monumental for the people of that era, which suggests that the cairn could only have been built by a wealthy, well-organized society. Researchers tentatively labeled it a "cairn," which is a mound of rough stones that might have once served as a landmark or a memorial.Īccording to Live Science, some researchers think the structure dates back 4,000 years. Weirdly, there appeared to be no order to the placement of the boulders, but still, the structure was definitely made by humans and was probably originally built on land before it was eventually swallowed up by rising waters. In the summer of 2003, researchers were conducting a sonar survey of the southwest portion of the Sea of Galilee in Israel when they discovered a submerged circular structure made of huge basalt boulders. Thanks for pooping on that party, Martin. That more supports the theory that the Saqqara bird was a toy that coincidentally happened to resemble an airplane. In 2002 a glider designer named Martin Gregorie made a working model of the Saqqara bird, which demonstrated that the bird would have needed a tail wing stabilizer (missing on the original model) in order to fly and that even with that addition it was still not super aerodynamic. Sometimes these little projects kind of just prove what everyone wants them to prove, though, and not every reproduction of the Saqqara bird has had similarly wowing results. In fact a couple people have tested working replicas of the Saqqara bird and say that it would have been capable of generating lift. Also, papyrus documents found near the artifact contain the words "I want to fly." That's led certain people, including the guy who found the thing in 1898, to hypothesize that the Saqqara bird is actually a model of a literal airplane that the ancient Egyptians either built themselves or saw someone else fly. It's roughly 2,200 years old and it looks, frankly, like an airplane with a bird's head. According to Ancient Origins, the Saqqara bird was discovered in 1898 in the Padiimen tomb.
