On Short Exponential Sums Involving Fourier Coefficients of Holomorphic Cusp Forms [PDF]
, 2008 By an exponential sum of the Fourier coefficients of a holomorphic cusp form we mean the sum which is formed by first taking the Fourier series of the said form,then cutting the beginning and the tail away and considering the remaining sum on the real ...

Uniform Estimates of Entire Functions by Logarithmic Sums
, 1997 We give uniform estimates in the whole complex plane of entire functions of exponential type less than a certain numerical constant (approximately equal to 0.44) having sufficiently small logarithmic sums.

Logarithmic speeds for one-dimensional perturbed random walk in random environment
, 2007 We study the random walk in random environment on Z+ = f0; 1; 2; : : :g, where the environment is subject to a vanishing (random) perturbation. The two particular cases that we consider are: (i) random walk in random environment perturbed from Sinai's ...

Extreme value theory for moving average processes with light-tailed innovations [PDF]
, 2005 We consider stationary infinite moving average processes of the form $Y_n = \sum c_i Z_{n+i}$, where the sum ranges over the integers, (Z_i) is a sequence of iid random variables with ``light tails'' and (c_i) is a sequence of positive and summable ...

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Estimates of character sums with exponential function [PDF]
Acta Arithmetica, 2001 Let \(n \geq 2\) and \(\lambda\) be integers satisfying \((n, \lambda)=1\) and \(\lambda\) belonging to the exponent \(d\) modulo \(n\). Given a primitive Dirichlet character \(\chi\) mod \(n\) the author proves the estimate \[ \left|\sum_{x=1}^X \chi(a \lambda^x +b) \right|< \sqrt{n} \left( \frac{2}{\pi} \log n + \frac{7}{5} \right).

Quasi-Diagonal Behaviour and Smooth Weyl Sums [PDF]
, 2000 Estimates are provided for small moments of exponential sums over smooth numbers substantially sharper than available hitherto. These bounds arise from the author’s recent breaking of “classical convexity” in Waring’s problem.

Advanced Engineering Materials, EarlyView.This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.
