Scholz noted that NATO and the U.S. Moscow that Germany supports, "and we now expect a reaction, an answer to them from Russia." He urged Russia to accept offers of dialogue. The German chancellor said in case of military escalation, "we are ready for very far-reaching and effective sanctions in consultation with our allies" and that "we know what to do" if Russia were to violate Ukraine’s territorial integrity again. Separately, U.N. Secretary-General Antonio Guterres held talks Monday with the foreign ministers of Russia and Ukraine and again underlined that "there is no alternative to diplomacy" to resolve the dispute over Ukraine. WHEN COULD RUSSIA MAKE ITS MOVE? British Prime Minister Boris Johnson says Europe is "on the edge of a precipice," citing an American warning that Russia could invade Ukraine in the next 48 hours. "But there is still time for President Putin to step back," Johnson said. U.S. officials said the Russian military has continued its buildup. Apparent attack preparations along Ukraine’s borders. Thus, understanding the mechanisms driving cancer cell migration is critical to characterize highly metastatic cells, develop new efficient treatments and improve precision medicine. Due to the experimental complexity, most quantitative cell migration studies are performed on 2222D cell culture experiments, while cell migration naturally occurs in 3333D environments (i.e., the extracellular matrix (ECM)). Instead of the lamellipodia or filopodia usually observed in 2222D substrates, cells migrating in 3333D substrates (e.g., collagen type I matrices) form dendritic protrusions to anchor, exert forces, and propel. Sample phototoxicity and photobleaching are well-known constrains in fluorescence microscopy. Thus, prolonged time-lapse videos are customarily acquired using brightfield microscopy techniques such as phase contrast, at the expense of low contrast between the cell and the background. Additionally, the brightfield images of collagen matrices are full of artifacts and quite heterogeneous due to the polymerization of the collagen fibers resulting in images full of artifacts. See Figure 4 in the Appendix. 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.

As a fundamental vision-language problem, TSGV also serves as an intermediate step for various downstream vision-language tasks, such as video question answering and video grounded dialogue. These tasks require to localize relevant moments about questions, then discover or generate answer to input question by analyzing the retrieved moments. Naturally, TSGV connects computer vision (CV) and natural language processing (NLP) communities, and benefits from advancements made in both areas. TSGV also shares similarities with some classic tasks in both CV and NLP. CV is to detect video segments, which perform specific actions, from video. Although VAR localizes temporal segments with activity information, it is constrained by the predefined action categories. TSGV is more flexible, and aims to retrieve complicated and diverse activities from video via arbitrary language queries. In this sense, TSGV needs semantic understanding of both video and language, and the multimodal interaction between them. On the other hand, the ease with which you can view RSS headlines may convince you that you can subscribe to even more sites. You may end up spending just as much time reading feeds as you used to on regular Web sites. Reading feeds requires a few simple things, many of which you already have. You'll need a computer -- or compatible electronic device -- and an Internet connection. After that, you need something that can read, or aggregate, RSS files. Aggregators collect. Interpret RSS feeds in one location. That way, you can see the latest headlines from HowStuffWorks, CNN, the BBC and Reuters, all in one place. Or do you just want the headlines? Do you want everything organized by date, with the feeds mixed by most recent, or would you prefer to keep each site separate? These are options that your aggregator will give you help you enjoy your reading. Aggregators take many forms.|President Joe Biden warned Russia's Vladimir Putin on Thursday that the U.S. Russia if it takes further military action against Ukraine, while Putin responded that such a U.S. The two leaders spoke frankly for nearly an hour amid growing alarm over Russia's troop buildup near Ukraine, a crisis that has deepened as the Kremlin has stiffened its insistence on border security guarantees and test-fired hypersonic missiles to underscore its demands. A lot of mistakes have been made over the past 30 years, and we would better avoid more such mistakes in this situation," Ushakov said. Russia's demands are to be discussed during the talks in Geneva, but it remains unclear what, if anything, Biden would be willing to offer Putin in exchange for defusing the crisis. Draft security documents Moscow submitted demand that NATO deny membership to Ukraine and other former Soviet countries and roll back military deployments in Central and Eastern Europe. The U.S. and its allies have refused to offer Russia the kind of guarantees on Ukraine that Putin wants, citing NATO’s principle that membership is open to any qualifying country. This is because any explainer video that involves only talking may not be lucrative enough hence you need animated videos. In modern times like now, one hardly finds time for making the first impression that shall be remembered by people. Once, you are gifted with this opportunity then it needs to be utilized in best ways possible because you want to achieve extraordinary results. Thus, they have become an important ingredient for marketing strategies that are successful. Video Content Animation companies aim at making strategies in tune with optimization-on page, guidelines of the video brand, planning of content, planning of campaigns and strategy of videos. In the promotion toolbox video marketing is an addition that is new. The videos have to be optimized where the agencies take care of length of the video, dislikes, likes, comments and reactions of customers, subscribers, relevance of keywords and watch time. Guidelines of the brand are specifically paid heed to so that it is able to build trust.

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 now, it’s a period of essentially tactical warning. But if Russia does decide to do something, it could be any day now, is how I would say it. When you say tactical warning, what do you mean by that? We’re really at the point where the next things that we might see really could be the things that Russia would do to actually start an attack. They don’t have to do a lot else to prepare militarily. They’re not literally up on the border, but they wouldn’t be. That doesn’t give them as much flexibility in where they cross. It’s in their interest to have some ambiguity about what they’re going to do. That ambiguity, however, comes from the fact that they have a great many things that they could do. They can threaten Ukraine from Crimea, and on the coastline in their south and especially in the southwest. They border, or are, in some cases, already inside Ukraine in the Donbas, of course, as well as in Crimea.
