Sent to the readout electronics via Ethernet cables. For each section, the readout electronics consists of three Flash Analogue-to-Digital Converter (FADC) boards. They convert the analogue signal to a 12 bit digital signal with a sampling rate of 250 MHz rate for 24 channels. Among those 24 channels, 23 are used for tank signals and the last channel is used to trigger the readout during calibration with a laser. The trigger decision is taken by the FPGA on board each FADC card, independently from the others. This implies that the whole array is effectively divided into 15 independent sub-arrays. In order to declare a trigger, at least 2 channels out of the 23 tank channels with a signal above 1 photo-electron (pe) within a time window of 160 ns are required. When those conditions are met, the 24 channels are read out for 200 ns before and after the trigger time and the traces are sent via 10 GBit optical fibres to the main server where the data reduction is performed.|Are you team bat or team dolphin? The scientists have weighed in. The score is super close. Without burdock burrs, squid nerves and kingfisher beaks - respectively - we wouldn't have Velcro, Schmitt Trigger input circuits or the high-speed Shinkansen bullet train. Engineers love to mine the natural world for ideas. Echolocation is another example where nature beat mankind to the punch. Echolocation is the process of detecting or examining an object by hitting it with high-frequency sound waves, which then bounce back to the source. Sonar technology has enabled humans to do this for more than 100 years, but numerous toothed whales - a lineage that includes dolphins, porpoises, and sperm whales - utilize echolocation. So do around 1,000 bat species. As sonar engineering continues to evolve, future inventors will probably derive lots of inspiration from bats and toothy cetaceans alike. But which group will be more valuable to the pioneers of tomorrow? That question has led to some playful ribbing among scientists. Moreover, the antioxidants in food may be beneficial. In fact, studies show that eating antioxidant-rich foods, such as fruits and vegetables, lowers the risk of heart disease; however, evidence suggests that antioxidant supplements do not lower risk. This may be because lifelong exposure to an antioxidant-rich diet -- before atherosclerosis or signs of heart disease develop -- may offer better protection. The only way you can be assured of getting the full complement of health benefits vitamins, minerals, and antioxidants offer is to make food your primary source of nutrients, and consider supplements only to reach any higher dosages that may be needed. This approach also means that any possible toxicity that accompanies very high intakes of some supplements will be avoided. Next, learn about antioxidants and vitamins that can help your cholesterol levels. This information is solely for informational purposes. IT IS NOT INTENDED TO PROVIDE MEDICAL ADVICE.

Kremlin says Putin starts nuclear drills, no invasion plan. With Western fears of war rising, foreign ministers from G7 nations said they had seen no evidence that Russia is reducing military activity near Ukraine's borders and remained "gravely concerned" about the situation. After Kyiv and Moscow traded accusations over new shelling incidents near the border, France and Germany urged all or some of their citizens in Ukraine to leave, and U.S. Defence Secretary Lloyd Austin said Russian forces were beginning to "uncoil and move closer" to the border. Austin told a news conference in Lithuania, saying an invasion of Ukraine was not inevitable. Russia ordered the military buildup while demanding that NATO prevent Ukraine from ever joining the alliance, but it says Western predictions that it is planning to invade Ukraine are wrong and dangerous. bbc
