High precision physics at future colliders as the International Linear Collider (ILC) require unprecedented high precision in the determination of the energy of final state particles. The needed precision will be achieved thanks to the Particle Flow algorithms (PF) which require highly granular and hermetic calorimeters systems. The physical proof of concept of the PF was performed in the previous campaign of beam tests of physic prototypes within the CALICE collaboration. One of these prototypes was the physics prototype of the Silicon-Tungsten Electromagnetic Calorimeter (SiW-ECAL) for the ILC. In this document we present the latest news on R&D of the next generation prototype, the technological prototype with fully embedded very front-end (VFE) electronics, of the SiW-ECAL. Special emphasis is given to the presentation. 250 GeV - 1 TeV. ILC requires unprecedented precision in the energy determination of final states. These techniques rely on single particle separation in the full detector volume to choose the best information available to measure the energy of the final state objects (i.e. measuring the charged particles momentum at tracking devices better than in the calorimeters). Therefore, PF algorithms require highly granular and compact calorimeter systems featuring minimum dead material (high hermeticity).
Electronic cigarettes closely resemble the real thing. You're at your favorite restaurant, enjoying a meal. A diner at the next table is puffing on a cigarette, letting out a cloud of smoke. Because smoking isn't allowed in the restaurant, you're thinking about asking the smoker to put the cigarette out. But before you protest, consider this: Your neighbor may not be smoking at all. Electronic cigarettes, also known as smokeless cigarettes, e-cigarettes, or e-cigs, are an alternative method of consuming nicotine, the addictive chemical found in tobacco. Manufacturers often design e-cigarettes to look like regular cigarettes, but they contain no tobacco and don't require a match -- or any flame at all. There's no fire, no ash and no smoky smell. E-cigarettes do not contain all of the harmful chemicals associated with smoking tobacco cigarettes, such as carbon monoxide and tar. Manufacturers and satisfied customers say the e-cigarette is a healthier alternative to tobacco cigarettes, which cause millions of deaths every year.
For the studio, however, it could have been more about the perception of what it means to pass the $100 million mark. Hollywood's bar for success changes, but these days hitting or missing $100 million on the opening weekend can mean the difference between a verifiable hit and an arguable flop. That's a lot of pressure on one movie, but history has shown that the autobots can bear the weight. In fact, Transformers movies are expected to break records. As that audience grows in other countries, blockbuster success and enormous box office numbers during opening weekend have become part of a movie's promotional campaign. Bringing in less than estimated box office numbers during the first weekend could send the wrong signals to the media and, by extension, the audience. Let's look at how - and why - Hollywood continues to play fast and loose with box office numbers. Box office projections can carry weight with moviegoers who are on the fence about committing a chunk of change on the theater experience.
Acoustic levitation allows small objects, like droplets of liquid, to float. Unless you travel into the vacuum of space, sound is all around you every day. But most of the time, you probably don't think of it as a physical presence. You hear sounds; you don't touch them. The only exceptions may be loud nightclubs, cars with window-rattling speakers and ultrasound machines that pulverize kidney stones. But even then, you most likely don't think of what you feel as sound itself, but as the vibrations that sound creates in other objects. The idea that something so intangible can lift objects can seem unbelievable, but it's a real phenomenon. Acoustic levitation takes advantage of the properties of sound to cause solids, liquids and heavy gases to float. The process can take place in normal or reduced gravity. In other words, sound can levitate objects on Earth or in gas-filled enclosures in space.
FoV prediction scheme, HOP, which jointly exploits the viewer’s historical FoV trajectory and target tracking through a long short-term memory (LSTM) network. Content-based methods usually extract a salient feature heatmap from video content, which can be considered as the most attractive part in a video frame. Because 360-degree videos are difficult to store and process in the spherical domain, they are usually projected onto a two-dimensional (2D) plane using equal rectangular projection (ERP), cylindrical projection (CYL), or truncated pyramid projection (TPP), which leads to distortion. One way to eliminate the distortion effect is to change the projection method. CNNs. However, this approach does not eliminate distortion, but only minimizes its effect. Moreover, the face boundaries introduce additional discontinuities that may require subsequent processing to combine the six image planes outputs. Another approach is to change the convolution method. However, the shape of the filter in their scheme depends on the longitude of the patch on the sphere, leading to non-sharing of the convolution kernel parameters and making the computational and storage costs much higher.
