Gamma-camera applicationsThe gamma-ray camera could be used in early drug development and nuclear medical imaging. It could be used to analyze the distribution of human bodies and radioactive markers. It could also be used to quickly and accurately locate radioactive sources, estimate environmental dose rates, and identify the types of radioactive natures, so as to achieve the purpose of quickly and accurately describing the on-site radiation environment. It could serve various purposes such as radiation protection, risk assessment, dose monitoring, anti-security, and so on.

gamma-ray burstA gamma-ray burst, also known as a gamma-ray burst, was a phenomenon in which the intensity of gamma-rays from a certain direction in the sky suddenly increased and then rapidly weakened in a short period of time (0.1 - 1000 seconds). The radiation was mainly concentrated in the energy range of 0.1 - 100 MeV. It was discovered during the Cold War when American spy satellites were monitoring nuclear explosions in 1967. The discovery was published by scientists in 1973.
The source could be the supernova explosion of a massive star at the end of its life, or the collision and merger of compact celestial bodies (such as neutron stars, black holes, etc.). The energy released in a short period of time could be comparable to or even higher than the total energy released by the main sequence star stage of the sun for 10 billion years. The source galaxy was billions of light-years away, and the energy of the explosion was extremely high and extremely rare. All the explosions observed by humans originated from outside the Milky Way, but the magnetars in the Milky Way would produce similar soft gamma-ray repeated bursts.
After the initial gamma-ray flash, it usually emitted an "afterglow" with a longer length (such as X-rays, violet rays, visible light, infrared rays, microwave rays, and radio waves) and a longer duration. Before 1997, due to the lack of observational data, there was no recognized theoretical model for the explosion phenomenon. Since 1997, with the observation of X-rays and visible light afterglow while detecting gamma-ray bursts, the red shift of visible light afterglow could be calculated using techniques such as the spectral analysis.
For example, in the Ordovician-Silurian extinction event about 445 million years ago, there was a hypothesis that gamma-ray bursts caused the event. At that time, the gamma-ray burst source was about 6000 light-years away from Earth. The gamma-ray beam swept across the Earth for about 10 seconds. Although the energy density was greatly reduced due to the distance, it was not enough to directly kill living things. However, it destroyed the Earth's atmosphere, destroyed the oxygen layer, and exposed the Earth's surface to infrared radiation. It also caused nitrogen and oxygen molecules to disintegrate to form free radical, which then re-combined to form nitrogen and oxygen compounds. These substances formed an smog to block sunlight. As a result, photosynthesis could not be carried out effectively, the bottom of the food chain broke, the temperature dropped, the sea level fell, and a series of consequences caused about 85% of species to go extinct.
On October 9,2022, the brightest gamma-ray burst was discovered 2.4 billion light-years away from Earth. Its energy was equivalent to eight solar masses multiplied by C squared. Because it lasted longer than two seconds, it was determined to be caused by the collapse of a massive star's core.(The other type is caused by the merger and explosion of two extremely dense celestial bodies such as neutron stars or black holes. The duration is usually less than 2 seconds and the gravitational waves are emitted at the same time.) This discovery was discovered by China's Huiyan satellite and the polar eye satellite. The Institute of High Energy Physics of the Chinese Academy of Sciences and 41 scientific research institutions around the world jointly published the research results.

115 pounds to 105 pounds to lose weightThere are several ways to help you lose weight from 115 pounds to 105 pounds. First of all, you can reduce your intake of calories by controlling your diet. For example, you can reduce your sugar intake and choose low-sugar or sugar-free sugar substitutes to satisfy your appetite. In addition, you can try the 16+8 diet, which means that you only eat for 8 hours a day and remain on an empty stomach for the rest of the time. In addition, exercise was also the key to losing weight. You can choose the exercise that suits you, such as oxygen exercise, oxygen exercise, strength training, etc., and stick to it a few times a week. However, one should be careful not to pursue a weight that was too low, because everyone's height and weight had a certain reasonable range. The most important thing was to maintain a healthy lifestyle and good physical condition.

What's the meaning of 'gamma'?In the video camera, the term "gamma-ray" referred to the characteristic of the gamma-ray. It was the curve characteristic formed in the non-linear circuit after being processed by the gamma-ray correction circuit. This feature was more suitable for high-definition camera technology, where the slope processing of the highlight part was called the knee processing. The cameraman could use the precise digital processing circuit to fine-tune the camera's gamma-characteristic, thereby achieving effective control over the image's tone level and high definition. Different cameras may be equipped with different gamma-curves. For example, the LUMIX BGH1 camera had a built-in V-LogL gamma-curve, and the Canon R5C had a Canon Log3 gamma-curve. These gamma-curves were suitable for different post-production needs, such as simple layering and color adjustment. In terms of the color correction process, different broadcasting platforms also had different reference settings for gamma-correction. For example, TV stations broadcast TV series/documentaries as REC709 GAMMA2.4, online platform drama series/online platform as REC709 GAMMA2.2, cinema P3 -DCIGAMMA2.6, etc.

What is the gamma-ray of the camera?Gamma-rays were a type of high-energy electromagnetic radiation with extremely short wave-lengths and high energy. However, in the field of photography, the gamma-value was different from the gamma-ray. The gamma-value was the response curve of the human eye to light, which could be considered as the brightness value. The brightness value of different gamma-mode imaging was different. There was no photography mechanism or equipment specifically called "gamma-ray" that used gamma-rays for conventional photography. In the information mentioned, gamma-ray imaging was used in the medical field (such as the portable gamma-ray camera developed by British scientists for cancer diagnosis and imaging), astronomy (such as the pancake film on balloons to take gamma-ray beam photos, detecting pulsar gamma-rays, etc.), and not in the traditional sense of photography (such as camera photography).

cotton shortsPure cotton shorts had many advantages in terms of material. For men, there were men's cotton underwear, men's sports boxers, cotton boxers, etc., which were more affordable. For example, men's cotton underwear in Zhongshan City only cost 3.79 yuan. Women's cotton shorts had 100% cotton anti-bacteria crotch, and the price was about 5.51 yuan. In terms of material selection for cotton shorts, high-quality linen and cotton were good choices. They had good breathability, strong moisture absorption, and were comfortable to wear. They could avoid the crumpled and cheap feeling. Chiffon, silk, and other cotton shorts were more gorgeous and suitable for formal occasions. However, the price was relatively high and they needed to be carefully maintained. In terms of matching, cotton shorts can be matched with a variety of tops, such as an oversize loose T-shirt, using the "lower body missing" wearing method.(T-shirts can be added with fashionable prints, and shorts can be no longer than the hem of the clothes). Paired with thick-soled sneakers and socks, it can be used to decorate the leg shape. basic style T-shirts can be paired with denim shorts. Simple T-shirts with bright shorts and bright socks are more attractive. Bright pure color T-shirts with white denim shorts and embroidered silk scarves can shift the visual focus to the upper body. Striped T-shirts with beige denim shorts are a simple way to match. Girls could choose a pair of comfortable cotton shorts with suspenders at home.
