A bioinformatic census of bacterial genomes found large variations in the number of (monomeric) HPt domains identified in different bacterial phyla, with some genomes encoding no HPts at all. Relative to the number of histidine kinase and response regulators present in a genome, eukaryotes have more identifiable HPt domains than bacteria. [12]
Miller twist rule is a mathematical formula derived by American physical chemist and historian of science Donald G. Miller (1927-2012) to determine the rate of twist to apply to a given bullet to provide optimum stability using a rifled barrel. [1]
During the constrained HPT process, the material experiences shear deformation between a fixed and a rotating anvil, without losing its original dimensions. High pressure torsion (HPT) can be traced back to the experiments that won Percy Bridgman the 1946 Nobel Prize in Physics, though its use in metal processing is considerably more recent. In ...
That is, if CEP is n metres, 50% of shots land within n metres of the mean impact, 43.7% between n and 2n, and 6.1% between 2n and 3n metres, and the proportion of shots that land farther than three times the CEP from the mean is only 0.2%. CEP is not a good measure of accuracy when this distribution behavior is not met.
For example, imagine a plate wherein compound A is in wells 1–2–3, compound B is in wells 2–3–4, and compound C is in wells 3–4–5. In an assay of this plate against a given target, a hit in wells 2, 3, and 4 would indicate that compound B is the most likely agent, while also providing three measurements of compound B's efficacy ...
It was his first rally-style event since the election. Smoke curled around the lectern and sparklers shot up from the floor as the crowd stood and cheered the incoming president, who wore his ...
For the week, the S&P 500 and the Dow Jones Industrial Average rose more than 4.5%, while the Nasdaq Composite rose nearly 6%. In the week ahead, a fresh reading on inflation and retail sales will ...
Rotordynamics (or rotor dynamics) is a specialized branch of applied mechanics concerned with the behavior and diagnosis of rotating structures. It is commonly used to analyze the behavior of structures ranging from jet engines and steam turbines to auto engines and computer disk storage.
