SRS is noninvasive and not a surgical operation in the traditional sense. It delivers high doses of radiation precisely targeted at the tumor. It damages the DNA of the tumor cells and stops them from reproducing, which makes the tumors gradually shrink. While SRS on the brain or spine is ...
There is littlematterin outer space. It is a hard vacuum, without any air. This also makes it extremely cold. There are some stray particles andradiation, though. Ironically, even though space itself is cold, due to the lack of particles to interact with, it is difficult to get rid of ...
Transfer to the metastable state: Because Er3average +'s residence period in the metastable state is 10ms, a population inversion between the metastable and ground states is easy to generate. The laser radiation effect generates a huge number of photons that are identical to themselves, causing ...
Wire glass is made by feeding a welded wire net of a particular design into the molten glass just before it enters the rollers. The wire does not add to the strength of the glass but it does hold the lite (a cut piece of glass) in the window sash if it shatters. Wire glass is us...
What is greenhouse gas? A greenhouse gas lets the sun's rays warm the Earth's surface but restricts the heat from escaping into space. Specifically, these gases absorbinfrared radiationfrom the sun in the Earth's atmosphere and release it. Some of the heat released reaches the Earth, along...
Although the most thorough understanding of the role of targeted therapy with ablative radiation in oligoprogression is in NSCLC, a small but growing volume of data suggest that the same principles may be applicable to other malignancies (12). For example, a recently published case report from St...
72 Therefore, it may be that the control probability of colorectal carcinoma lung metastases is particularly dose-sensitive. Other histologies may also have different profiles of sensitivity to ablative radiation doses, with renal cell carcinoma73 and melanoma being reported as having particularly ...
Figure 14: Time Synthesis, SRS pulse and Error Spectrum In a shock response analysis, a wavelet decomposition is performed to produce an equivalent time history input that fits the shaker limits.More information on shock vibration testing: Shock Response Spectrum (SRS) Classical Shock Pulses Shock ...
However, the powering mechanism of these outflows is a highly debated topic and an ongoing area of research. In radio-loud (RL) AGN, there is evidence for the ionized gas outflows to be driven both by the radio jets [35,36,37], and also by the AGN radiation field (e.g., [20,38...
