3. Example of Adaptive Radiation: - A classic example of adaptive radiation is observed in Darwin's finches. These birds are found in the Galapagos Islands and are known for their diverse beak shapes and sizes. 4. Initial Condition: - Initially, Darwin's finches were seed-eating birds wi...
The work is applied in designing strong-field superconducting wigglers as synchrotron radiation sources, since homogeneity of a high-amplitude magnetic field is important for reducing the influence of the wiggler on the electron beam in the storage ring. An example of the method is presented for ...
To solve this problem, some researchers have focused on improving the electrical conductivity of Te-based thermoelectric devices13,14,15,16. Preparing composites of Te with other similar materials is a simple way to improve its thermoelectric properties. One example is the polymer-Te hybrid composite...
generates far more YPLLs than the bare figure of 20,000 deaths per year, bad as that is, might suggest.[10] Put differently, finding a cure for AIDS would be likely to add about 25 to 30 years to the life of each potential victim. Finding...
To clarify tho role of the RAD9, RAD17, RAD24, and RAD53 checkpoint genes in cell radioresistance, diploid double mutants were analyzed for cell sensitivity to ionizing radiation. All mutations in combination with rad9Δ were shown to manifest the epistatic type of interaction. Our results ...
In the method and by means of the device, several radiation sources (1) arranged in a row and whose emission intensity distribution is not rotationally symmetrical, are imaged using a first functional element (5), which images in a non-central fashion, then each beam (9) is rotated by a...
The concepts are validated with a compact device for 5G/4G/Wi-Fi 2.4/5/6E performing a beam steering in the 5G without disturbing the radiation patterns of the other bands. This device demonstrates that the functionalities of two metasurfaces may be exploited in a single design if the ...
For example, patients who can understand the study, agreed to accept and complete all the interventions of the study, and can be followed up in the stipulated timeframe. Exclusion criteria (1) Patients with anal trauma, inflammatory bowel disease, malignant tumours, HIV, tuberculosis, actino...
Nuclear radiation has a certain mystery about it partly because it cannot be detected (探测) by human senses. It can't be seen or heard or touched or tasted even though it may be all around us. There are other things like that. For example radio waves are all around us but we can'...
The novelty of the current work lies in the computationally efficient solution method for an infinite system which locally exhibits nonlinear behaviour and in the study into the influence of the foundation’s nonlinear behaviour on the generated waves (i.e., transition radiation), and on the ...
