In this document we will focus in the description of the silicon-tungsten electromagnetic calorimeter, SiW-ECAL, technological prototype and its performance in beam test. The design and R&D of this prototype is conducted by CALICE and it is oriented at the baseline design of the ILD ECAL. POSTSUBSCRIPT of thickness (in the barrel region) and it uses silicon (Si) as active material and tungsten (W) as absorber material. The combination of Si and W for the construction of the detector allows the construction of a very compact calorimeter made up of compact active layers with small cell size (high granularity) in the transverse and longitudinal planes. It will consist of an alveolar structure of carbon fiber into which the slabs made up of tungsten plates and active sensors will be inserted. The very-front-end (VFE) electronics will be embedded in the slabs. The silicon sensors will be segmented in squared cells of 5x5 mm, featuring a total of ?100similar-toabsent100sim 100? 100 million channels for the ECAL of the ILD.|If you can't go around a traffic jam, and you certainly can't go through one, the best bet may be to simply glide over it. That's what the developers of what's being called a "straddling bus" think, anyway, and they see it as one key element in the battle against China's notoriously gridlocked traffic. Introduced at the Beijing International High-Tech Expo this week, the elevated bus - called a Transit Elevated Bus (TEB) - would travel along tracks built along the side of roadways. Cars would pass through a gap beneath the bus, making for a roadway scene a little like Pac-Man chomping up cars instead of pellets. There were 126 million private vehicles in China in 2015, an increase of 15.5 percent over 2014, according to China's National Bureau of Statistics. But the current 2010 iteration was deemed unfeasible for real-world testing. Fast forward six years and technical kinks have been ironed out, apparently, and five cities in China have expressed interest in testing the vehicle. However, most said they had an emergency plan and would leave if fighting became more widespread. “A lot of people here are walking around with smiles on their faces,” Linton says. “If you walk down the street, you have no idea anything is actually happening because nobody complains. Linton says that while many people in Kyiv he has spoken to have emergency plans in place, should the situation worsen, he believes he will stay, regardless. He speaks Russian and plans to enroll in university in Ukraine to study science. He says many of the Ukrainians he knows say they are prepared to stay and fight, should the time come. He acknowledges that his parents have asked him to return home, but says he has reassured them that he is safe. “The fear is not here, the fear is everywhere else,” he says.
