The High Altitude Water Cherenkov (HAWC) observatory is a very high energy gamma-ray detector located in Mexico. In late 2018, the HAWC collaboration completed a major upgrade consisting of the addition of a sparse outrigger array of 345 small water Cherenkov detectors (WCDs) surrounding the 300 WCDs of the main array and extending the instrumented area by a factor of 4. It provides an improved reconstruction of the showers whose core and footprint are not well contained in the array and increases the effective area in the range of a few TeV to beyond 100 TeV. This improvement in sensitivity will help to have a better understanding of the Galactic sources that accelerate particles up to the knee of the cosmic ray spectrum. In this contribution, we will show the current status, the performance, and the first results from the HAWC outrigger array. The High Altitude Water Cherenkov (HAWC) is a very-high-energy gamma-ray observatory located at 4100 m altitude on the volcano Sierra Negra in the state of Puebla in central Mexico.
First, gravity is a force that causes objects to attract one another. The simplest way to understand gravity is through Isaac Newton's law of universal gravitation. This law states that every particle in the universe attracts every other particle. The more massive an object is, the more strongly it attracts other objects. The closer objects are, the more strongly they attract each other. An enormous object, like the Earth, easily attracts objects that are close to it, like apples hanging from trees. Scientists haven't decided exactly what causes this attraction, but they believe it exists everywhere in the universe. Second, air is a fluid that behaves essentially the same way liquids do. Like liquids, air is made of microscopic particles that move in relation to one another. Air also moves like water does -- in fact, some aerodynamic tests take place underwater instead of in the air. The particles in gasses, like the ones that make up air, are simply farther apart and move faster than the particles in liquids.
It’s a natural part of living in the information age: You start to feel sick, so you Google your symptoms. Both the common cold and the flu will make you feel miserable, and because both are respiratory infections with similar symptoms - coughing, aching, headache, you know the drill - it can be difficult to know which one has you in its grip. Every year, anywhere from five to 20 percent of the U.S. While many sufferers will find relief in over-the-counter medicines, influenza can be serious. Influenza-related complications may require hospitalization, and sometimes complications can be fatal. Influenza, together with pneumonia (both are lower respiratory infections), ranked as the eighth leading cause of death in the U.S. For its tracking purposes, the CDC considers a fever of at least 100 degrees Fahrenheit (37.8 degrees Celsius) with a cough and/or a sore throat to be an ILI. Beginning on the 40th week of the year - which is the beginning of the October to May flu season - the CDC distributes weekly influenza activity reports.
Is traversed by the famous San Andreas Fault. Some of its most spectacular features include the white alkali flats of Soda Lake and its vast grasslands, which, can be carpeted with wildflowers when conditions are right. Berryessa Snow Mountain National Monument includes nearly 331,000 acres (133,951 hectares) of rolling hills and steep canyons in northern Californias Inner Coast Range. The land surrounds the farms, ranches and orchards that stretch from Napa County to the mountains of the Mendocino National Forest. The 1.6-million-acre (647,497-hectare) Mojave Trails National Monument features mountain ranges, ancient lava flows and fossil beds, and sand dunes. It's also home to rare plants and many native animals, and links the Pacific coast to the deserts of the Southwest. Sand to Snow National Monument encompasses 154,000 acres (62321.5 hectares) in southern California, which are home to more than 240 species of birds and 12 threatened and endangered animals. The area also includes sacred archaeological and cultural sites, as well as nearly 1,700 Native American petroglyphs.|LONDON, Feb 24 (Reuters) - Oil prices jumped on Thursday, with Brent rising above $105 a barrel for the first time since 2014, after Russia's attack on Ukraine exacerbated concerns about disruptions to global energy supply. Russia launched an all-out invasion of Ukraine by land, air and sea in the biggest attack by one state against another in Europe since World War Two. The United States and Europe have promised the toughest sanctions on Russia in response. Commerzbank analyst Carsten Fritsch. At least three major buyers of Russian oil were unable to open letters of credit from Western banks to cover purchases on Thursday, sources told Reuters. Brent crude was up $8.15, or 8.4%, at $104.99 a barrel as of 1221 GMT, having touched a high of $105.79. U.S. West Texas Intermediate (WTI) crude jumped $7.33, or 8%, to $99.43. Brent and WTI hit their highest since August and July 2014 respectively. UBS analyst Giovanni Staunovo.
Instead, it will be built into a tough but pliable fabric frame. Even the screen will able to bend and fold and will have a thickness and flexibility similar to a laminated sheet of paper. Furthermore, how could it be predicted to hit the market in just a few years? Experts say it will be available in 2 to 10 years. Find out why this technology really is right around the corner and why some of its seemingly futuristic features aren't actually so different from what's being offered by products available on the market today. Keep reading to learn how a computer could be built within a flexible fabric frame instead of a more traditional rigid metal housing. Conventional computer hard disk drives are large and bulky, but flash memory, common today in memory sticks and cameras, is a possible lightweight alternative for memory storage in the laptops of tomorrow. To understand how a laptop computer could be designed to be flexible, let's first consider why conventional laptops aren't flexible.|A lot of people share the same interests. They may love sports, movies, food, and others. They usually share some things to each other. One such example will be fan made videos. A lot of anime fanatics usually make these things. The following tips can help them create these videos from new anime trailers. The individual should be creating the concept for the video he wants to be making. Many concepts are available. He could be making a video about love, sports, or comedy, among others. If he wants to, he could be creating a video that is personifying his life or emotions. Most people are typically utilizing such concept. Once their own concepts are known, the clips that are wanted to be used should be downloaded. The clips should be related to their own concepts. They need to ensure the validity and safety of the websites or sources where these clips will be downloaded from.
