For one, a tornado's winds intensify with height, meaning that even the short climb up under an overpass could put you at greater risk of injury from flying debris. What's worse, the overpass's design results in a wind tunnel effect, meaning gusts actually increase in speed as they're funneled through the narrow space under the end of the bridge. These dangers were tragically demonstrated in 1999 when a powerful tornado killed three people. Severely injured others who sheltered under overpasses in Oklahoma. The best thing to do if you see a tornado while driving is to get out of the way and find the nearest shelter - but only if traffic and road options allow. If this isn't possible, take cover in a ditch or culvert and cover your head with your hands. Sorry, businessman. Unless one corner of your basement has windows, one hiding spot is no better than another.|Are your cleaning products eco-friendly? What's the smartest step you can take to help reduce pollution and live in a more sustainable way? It might simply be to take a look at the environmental impact of the things you buy. Choosing eco-friendly products is not just a fad, nor has the economic downturn slowed the trend. A 2009 study by nonprofit research group Green Seal and EnviroMedia Social Marketing found that about four out of five people said they bought green products despite the recession. Eco-friendly consumerism may involve making some complicated decisions. For example, a new refrigerator may be more energy efficient than the one you own now, but a good deal of energy goes into manufacturing any appliance to begin with. Is it more eco-friendly to buy the new one or stick with the old if it still works? Likewise, buying locally grown food cuts the energy used for transportation, but growing them in a greenhouse might use just as much energy. Nevertheless, an accurate result must be guaranteed with a proper parameter setting. As we illustrate in Fig. 1 and Fig. 2, the hyperparameters are unavoidable to be handcrafted to achieve satisfactory performance in traditional algorithms. DEQ to solve the inverse problems in imaging, which corresponds to the potentially infinite number of iteration steps in the PnP reconstruction scheme. To accommodate the state-of-the-art SCI architectures and to enable low-memory stable reconstruction, this paper sets about utilizing DEQ for solving the inverse problem of video SCI. Specifically, we applied DEQ to two existing models for video SCI reconstruction: RNN and PnP. Therefore, the former one is equivalent to an infinite-depth network using only constant memory; the latter one is tuning-free, and directly solves for the fixed point during the iterative optimization process. On a variety of simulations and real datasets, both quantitative and qualitative evaluations of our results demonstrate the effectiveness of our proposed method. coronavirus news
