one of the most important parts of range doppler algorithm is range cell migration correction. in this part, an interpolation approach is used to estimate data in their correct location. the interpolation method has a great influence on the quality of ultimate image. in this paper the interpolation method and different ways for increasing its accuracy was discussed. the performance of different...

As a simple rst step in a larger program of cooling R&D, we propose to study ionization cooling in an absorber without rf acceleration (\minicooling"). The absorber and emittance diagnostics reside inside a single 2.5-T solenoid magnet placed at the end of a == quadrupole channel, either in a new beamline at FNAL, or more expediently in the existing D2 line at BNL. The ux of muons would be low,...

It is suggested that the propagation of the action potential is accompanied by an axoplasmic pressure pulse propagating in the axoplasm along the axon length. The pressure pulse stretchmodulates voltage-gated Na (Nav) channels embedded in the axon membrane, causing their accelerated activation and inactivation and increasing peak channel conductance. As a result, the action potential propagates...

In modern computer systems, long-running jobs are divided into a large number of short tasks and executed in parallel. As the system size and complexity scales up, the task service times become highly random and the job service time is constrained by the slowest straggling tasks. An efficient solution is to replicate a task on multiple servers and wait for one task copy to finish early. However...

Population protocols are networks of finite-state agents, interacting randomly, and updating their state using simple rules. Despite their extreme simplicity, these systems have been shown to cooperatively perform complex computational tasks, such as simulating register machines to compute standard arithmetic functions. The election of a unique leader agent is a key requirement in such computat...

Reader-writer locks (rwlocks) aim to maximize parallelism among readers, but many existing rwlocks either cause readers to contend, or significantly extend writer latency, or both. Further, some scalable rwlocks cannot cope with OS semantics like sleeping inside critical sections, preemption and conditional wait. Though truly scalable rwlocks exist, some of them cannot handle preemption, sleepi...

By taking the spin and polarization of electrons, positrons photons into account in strong-field QED processes nonlinear Compton emission pair production, we find that growth rate cascades ultra-intense laser fields can be substantially reduced. While this means fewer particles are produced, also found them to highly polarized. We further high-energy tail particle spectra is polarized opposite ...

In the design of ultralow leakage devices such as image sensors, it is necessary to understand influence low-density defects during plasma processing-plasma-induced physical damage (PPD)-on device performance. Defects created by exposure act carrier conduction sites and induce an increase in (e.g., dark) current. This study proposes a PPD evaluation scheme for defect assessments, specifically l...
