Once a computer virus is running, it can infect other programs or documents. Obviously, the analogy between computer and biological viruses stretches things a bit, but there are enough similarities that the name sticks. People write computer viruses. A person has to write the code, test it to make sure it spreads properly and then release it. A person also designs the virus's attack phase, whether it's a silly message or the destruction of a hard disk. Why do they do it? There are at least four reasons. The first is the same psychology that drives vandals and arsonists. Why would someone want to break a window on someone's car, paint signs on buildings or burn down a beautiful forest? For some people, that seems to be a thrill. If that sort of person knows computer programming, then he or she may funnel energy into the creation of destructive viruses. The second reason has to do with the thrill of watching things blow up. But Ukrainian language and culture is noticeably different, and it’s really hard for Russians to get this. Although Ukraine had been part of the Russian empire at various points in history, Soviet propaganda cemented the idea, at least in older generations of Ukrainians, that their country was intertwined with the Soviet Union, and indeed was "Little Russia," as Volodymyr Kravchenko explains in Harvard’s journal of Ukrainian studies, though in reality Ukrainian nationalism existed in some form throughout the 20th century. In the present day, Putin’s insistence that Russia and Ukraine are historically and "spiritually" the same country allows him to push another narrative - that Ukraine’s openness to joining NATO and increasing alliances with the US and European countries is both a betrayal and somehow disingenuous, a sinister plot to tear the two nations apart. However, Soviet-era mythologizing - and Putin’s current amplification thereof - of Ukraine as a Russian appendage is powerful. " Jensen told Vox. So you end up ignoring the changes inside a society.|The thumbnail, as the first sight of a micro-video, plays pivotal roles in attracting users to click and watch. Although several pioneer efforts have been dedicated to jointly consider the quality and representativeness for selecting the thumbnail, they are limited in exploring the influence of usersâ interests. While in the real scenario, the more the thumbnails satisfy the users, the more likely the micro-videos will be clicked. In this paper, we aim to select the thumbnail of a given micro-video that meets most usersâ interests. Towards this end, we construct a large-scale dataset for the micro-video thumbnails. Ultimately, we conduct several baselines on the dataset and demonstrate the effectiveness of our dataset. Micro-video Understanding, Thumbnail Selection, Deep Learning. Considering Instagram as an example, as of June 2018, over 30 million micro-videos had been shared daily, but about 70 percent of them had not been watched. To retain usersâ stickiness, beyond improving the quality of micro-videos, micro-video platforms and publishers have to draw usersâ eyes quickly. Unfortunately, a gas mask won't do you much good in the event of a large-scale bioterrorist attack. The attacks of Sept. 11, 2001, alerted the world to the realities of new terrorist threats. Startling images of the Twin Towers falling are indelible. May have overshadowed the events that occurred just a week later. From a public mailbox in New Jersey, letters that contained anthrax spores were mailed to two U.S. The attack killed five people. Bioterrorism -- the purposeful release of bacteria, viruses or germs to cause injury, illness or death -- became a reality in the United States. The three ways a terrorist can release biological agents is through air, water or food. These agents are typically very difficult to detect and because the illnesses they cause are usually delayed, it makes bioterrorism a hard crime to investigate. In fact, the anthrax case of 2001 remains unsolved. Human bodies infected with plague were also used as ammunition in central Europe during the 14th and 15th centuries.

Before undertaking any course of treatment, the reader must seek the advice of their physician or other health care provider. Antioxidants include some vitamins and minerals, but to appreciate the value of antioxidants, you first need to understand the potential dangers of free radicals, a form of oxygen that has been chemically modified into a highly unstable substance. Free radicals are unstable because they are missing electrons, which must be replaced. So they seek out other compounds in the body. Steal electrons to restore stability. If the compound giving up its electrons is the fat and protein in an LDL-cholesterol molecule, the result is the formation of fatty lesions in the walls of the blood vessels -- the hallmark of atherosclerosis. For instance, they form in the normal course of the day, just by our breathing in oxygen.|Smilodon fatalis, the saber-tooth cat: a little like a tiger and a little like a bear. See more pictures of big cats. It's easy to imagine that saber-tooth cats hunted the way today's tigers do -- after all, many people call the extinct felines "saber-tooth tigers." Tigers hunt alone, waiting until twilight and using vegetation or patches of light and shadow to hide themselves. A tiger will stalk its prey until it's close enough to strike in a couple of quick leaps. The kill comes when the tiger bites through the back of its victim's neck and severs the spinal cord. Tigers can also strangle their prey with a long-lasting bite to the throat. The most well-known of the extinct felines, Smilodon fatalis, shared some physical traits and hunting patterns with tigers. But saber-tooth cats may have been social animals, like today's lions. Many saber-tooth species also had the sheer physical bulk of bears. Today's big cats have long canines, too -- but they're tiny compared to the elongated teeth of a saber-tooth. We position this work as a first step in understanding the suitability of various object detection kernels on embedded boards in the accuracy-latency-energy axes, opening the door for much farther development in solutions customized to embedded systems and for benchmarking such solutions. With this, Virtuoso is able to achieve up to 286 FPS on the NVIDIA Jetson AGX Xavier board, which is up to 45 times faster than the baseline EfficientDet D3 and 15 times faster than the baseline EfficientDet D0. In addition, we also observe up to 97.2% energy reduction using Virtuoso compared to the baseline YOLO (v3) - a widely used object detector designed for mobiles. With this comprehensive benchmark, Virtuoso has shown superiority to all the above protocols, leading the accuracy frontier at every efficiency level on NVIDIA Jetson mobile GPUs. Video analytic systems have seen widespread success in various domains, ranging from computationally heavy tasks such as recognizing faces for surveillance, to mobile applications such as detecting objects for mobile-based augmented reality (AR) (Rohan et al., 2019; Apicharttrisorn et al., 2019; Rao et al., 2017), and to real-time systems such as localizing pedestrians and cars for autonomous driving (Feng et al., 2020; Arnold et al., 2019; Li et al., 2019). A key function shared by these applications is the ability to detect objects in videos. Hundreds cross the Brooklyn Bridge after the bombing of the World Trade Center in 2001. That was an example of a terrorist attack that succeeded but many others have not. If you're going to be a terrorist, you've got to play it cool. In 1999, would-be bomber Ahmed Ressam filled his car with explosives and drove it from Canada to the U.S. But at the very moment a customs inspector approached, he panicked and ran away. Ressam isn't the only terrorist whose destructive attempt has been thwarted. In the 12 years since the 9/11 attacks, an estimated 54 other terrorist attacks on the U.S. And these are only the attempts we know about, which have been publicly documented through news articles and official briefings. The actual count of "almost" attacks is likely much higher.S. And sometimes the terrorists themselves bungle the plan. Whatever the strategy to uncover current threats, there are powerful lessons to be found in examining previous plots that have failed.

Electrotactile stimulation is a higher-tech method of receiving somewhat similar (although more surprising) results, and it's based on the idea that the brain can interpret sensory information even if it's not provided via the "natural" channel. The brain then recreates the images from analysis of the impulse patterns. The multiple channels that carry sensory information to the brain, from the eyes, ears and skin, for instance, are set up in a similar manner to perform similar activities. All sensory information sent to the brain is carried by nerve fibers in the form of patterns of impulses, and the impulses end up in the different sensory centers of the brain for interpretation. To substitute one sensory input channel for another, you need to correctly encode the nerve signals for the sensory event and send them to the brain through the alternate channel. The brain appears to be flexible when it comes to interpreting sensory input. You can train it to read input from, say, the tactile channel, as visual or balance information, and to act on it accordingly.|You'll have to take the MCAT if you want to join these medical students someday. If you want to be a doctor when you grow up, you'll have to get past the MCAT first. The Medical College Admissions Test (MCAT) is a required part of the admissions process at every medical school in the U.S. Tests like the SAT, GRE, GMAT and LSAT are designed to assess your overall critical thinking and problem-solving skills, but shy away from testing specific subject area knowledge. That's not the case with the MCAT, which drills test-takers on a wide range of natural science topics spanning undergraduate coursework in physics, chemistry and biology. Studying for the MCAT is a full-time job for pre-med students who are intent on landing a coveted slot at a competitive medical school. In 2009, over 42,200 applicants applied for only 18,390 slots at U.S. Keep reading to learn exactly what kinds of questions are included on the MCAT and how you can prepare to take this imposing and important exam. Air conditioners are energy hogs, so if you want to go green, go off peak. Green energy is a big topic these days, and the list of ways to generate and manage energy more efficiently keeps growing. One innovative way to use energy wisely is through the use of off-peak cooling systems. Off-peak cooling is pretty ingenious because it uses energy at night when the demand is low. Air conditioning is an energy hog, and when some of the electricity needed to cool all that air is distributed over the evening and night hours, it takes some of the burden off the energy grid at the biggest demand times of the day. This redistributes the demand for electricity, helping to avoid brownouts and blackouts and also takes advantage of lower electricity rates during off-peak times. There are other benefits to off-peak cooling systems, too. Conventional air conditioners use more energy as they get hotter, and the more energy they draw, the less efficiently they use it. President Joe Biden has said he will not fight Russia in Ukraine, nor would America's NATO allies. So a Russian invasion would not automatically trigger a wider war. But if Putin took his offensive beyond Ukraine's borders onto NATO territory, the United States could get drawn into it. That's because Washington is obliged by the North Atlantic Treaty to defend its allies, some of whom fear they are Russian targets. "Make no mistake. The United States will defend every inch of NATO territory with the full force of American power," Biden said Tuesday. Beyond the seemingly unlikely scenario of Putin deliberately extending an invasion beyond Ukraine, there is a risk that even a limited war could spread as a result of an accident, a miscalculation or a misunderstanding. Once the fighting started, a bit of bad luck could lead to more conflict. An incident between American and Russian aircraft over the Mediterranean Sea that came to light Wednesday offered a glimpse at how even routine military movements can lead to unsafe results.
