Molecular evolution is usually described assuming a neutral or weakly non-neutral substitution model. Recently, new data have become available on evolution of sequence regions under a selective pressure, e.g. t

whereu,Uandpare the dynamic viscosity of water, velocity and pressure, respectively. The initial value ofUandpare zero in our simulation. The boundary condition on the activated particle is set to be the release or consumption of ions, representing the continuity of ion flux on the reaction he...
The widespread signatures ofnatural selectioncentred on loci contributing to increased resistance toxenobioticsinAnophelesacross Africa are likely associated with strong, rapid, nonspecific and recent human-mediated selection pressure such as thescaling upofLLINsusage. Nevertheless, urbanization, exposure to ...
Moreover, some environmental factors such as pH, operating pressure, flow velocities, feed and product concentrations, temperature fluctuations, and current density can affect ion transport and selectivity of ISMs (Sun et al., 2015). Mainly, the electrical field have a significant impact on ion ...
easy to integrate with electronics, and have the capacity for real-time, on-site measurements. The most common solid-state ion sensors are the ion sensitive field effect transistors (ISFETs), where the gate of the ISFET incorporates an ion selective membrane in the form of either a glass or...
This umbrella definition captures a range of measurements that may be representative of a disease course, from simple indica- tors like blood pressure to complex laboratory tests [2]. In this paper, we focus specifically on physical markers which are detectable via serum assays. In the past 20...
Generally, the reduction in pressure of a silencer is approximately 1000 Pa, whereas that of a static mixer is lower than 500 Pa. (2) Mixing distance The mixing distance refers to the distance from the urea spray nozzle to the point at which the mixed gas reaches the mixing section after...
easy implementation of both large area and high resolution, smooth morphology (need uniform electric field) leading to high-quality interfaces with optoelectronic devices. Thus, it can benefit large-scale devices with relatively high PPI, and can be easily integrated with photolithographic processes to...
