On the eigenvalues of zero-divisor graph associated to finite commutative ring
AKCE International Journal of Graphs and Combinatorics, 2021 Let Z(R) be the set of zero-divisors of a commutative ring R with non-zero identity and be the set of non-zero zero-divisors of R. The zero-divisor graph of R, denoted by is a simple graph whose vertex set is and two vertices are adjacent if and only if ...

Exponential and infinitary divisors [PDF]
, 2014 Our paper is devoted to several problems from the field of modified divisors: namely exponential and infinitary divisors. We study the behaviour of modified divisors, sum-of-divisors and totient functions.

Wheat flour particle size: Influence of mill design and effects on quality and performance
JSFA reports, EarlyView.Abstract Among the various characteristics of wheat (Triticum aestivum) flour, particle size is of paramount importance globally. The industrial process of separating the three main components (endosperm, bran, and germ) must ensure that the desired quality is delivered to customers through a progressive reduction in the size of the endosperm until the

A Novel Two‐Stage Flexible Flow Shop Batch Scheduling Model for Grinding Workshops
Naval Research Logistics (NRL), EarlyView.ABSTRACT The growing need for data storage in data centers has increased the demand for mechanical hard disks due to their low cost and high reliability. Aluminum substrates are the most popular base plates for mechanical hard disks because of their high hardness and low cost.

Quarterly Journal of the Royal Meteorological Society, EarlyView.We investigate whether Central European heatwaves (HWs) forming under omega blocking differ from those enabled by subtropical ridges, in terms of both air‐mass origin and processes warming air parcels along their way. Using ERA5‐based backward trajectories and a Lagrangian temperature anomaly decomposition, we identify significant differences in the ...

Reduction of a pair of matrices to a special triangular form over a ring of almost stable range 1 (in Ukrainian) [PDF]
Математичні Студії, 2012 In the paper it is considered a notion of a ring of almost stable range 1. It is shown that an arbitrary pair of matrices over commutative Bezout domain of almost stable range 1, where at least one of the matrices is not a zero divisor, reduced to a ...

A Riemann-Roch theorem for edge-weighted graphs
, 2012 We prove a Riemann-Roch theorem for real divisors on edge-weighted graphs over the reals, extending the result of Baker and Norine for integral divisors on graphs with multiple edges.Comment: Minor revisions, 10 ...

The Quarterly Journal of Mathematics, 1938 Let \(\Delta_k(x)\) be the error term in the divisor problem of Piltz, so that \[ \sum_{n\le x} d_k(n) = P_k(x) + \Delta_k(x), \] where \(d_k(n)\) is the number of solutions of \(n_1\cdots n_k = n\) in positive integers \(n_1,\ldots n_k\), and \(P_k(x)\) is the residue of \(x^s \zeta^k(s)/s\) at \(s = 1\).

Rapid Communications in Mass Spectrometry, EarlyView.ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

Teaching Statistics, EarlyView.Abstract Statistical hypothesis testing (SHT) is widely employed across numerous scientific disciplines, and a clear understanding of its underlying logic is essential for the broader scientific community. Here, drawing upon both epistemological and statistical perspectives, we aim to clarify—primarily for educational purposes—the logical relationship ...
