This work proposes a novel framework to address straggling and privacy issues for federated learning (FL)-based mobile application services, considering limited computing/communications resources at users (MUs)/mobile provider (MAP), cost, the rationality incentive competition among MUs in contributing data MAP. Particularly, MAP first determines set of best FL process based on MUs' provided in...

Ion-optical calculations with the code TRANSPORT (TRANS) (test reaction 235 MeV Ca + UF4 (0.5 mg/cm) ==> 112) were used as a first step to optimize and to built TASCA [1,2]. As a next step the TASCA Monte-Carlo SIMulation program (TSIM) was developed and was applied [3] showing good agreement with previous results. Results for TASCA in the Small Image Size Mode (SIM) are compared in Table 1. Sm...

The knowledge of the energy-loss distribution in a single ion-atom collision is a prerequisite for subnanometric resolution in depth-profiling techniques such as Nuclear Reaction Analysis (NRA) and Medium Energy Ion-Scattering (MEIS). The usual Gaussian approximation specified by the stopping power and energy straggling is not valid for near surface regions of solids, where subnanometric or mon...

A ubiquitous problem in solid state analysis is the determination of the elemental composition of a sample as a function of the depth. The determination of the depth profiles from ion-beam experiments is an ill-posed inversion problem due to ion-beam and detector-induced energy spreads as well as energy-loss straggling and small-angle scattering effects. The inversion problem is solved in the f...

Gradient-based distributed learning in parameter server (PS) computing architectures is subject to random delays due straggling worker nodes and possible communication bottlenecks between PS workers. Solutions have been recently proposed separately address these impairments based on the ideas of gradient coding (GC), grouping, adaptive selection. This article provides a unified analysis techniq...

Slow running or straggler tasks can significantly reduce computation speed in distributed computation. Recently, coding-theory-inspired approaches have been applied to mitigate the effect of straggling, through embedding redundancy in certain linear computational steps of the optimization algorithm, thus completing the computation without waiting for the stragglers. In this paper, we propose an...

Various modern systems for the transport and manipulation of large acceptance beams of rare and short-lived particles require the treatment of nonlinear optics of acceleration, absorption, and focusing in a combined approach. We describe a differential algebraic method for the treatment of such nonlinear dynamics via high-order transfer maps. We include the processes of scattering and stragglin...

, A numerical solution to the integro-differential equation describing the energy'distribution of a beam of electrons which has passed through matter, losing energy by radiation only, has been obtained utilizing a finite difference mesh method. Solutions were obtained for thicknesses of up to 0.1 radiation lengths for a complete screening approximation to the energy loss equation. The accuracy ...
