Electronic spectroscopy of zero-dimensional (0D) quantum systems, including point defects in solids, atomic states, and small molecules, is a critical tool for developing a fundamental understanding of these systems, with applications ranging from so

Today, many countries, including Iran, face natural hazards such as ground subsidence, drought, floods, and acute water shortage. Lack of correct management of underground water resources leads to many of these natural hazards. Artificial recharge of

The aim of this paper is to solve large-and-sparse linear Semidefinite Programs (SDPs) with low-rank solutions. We propose to use a preconditioned conjugate gradient method within second-order SDP algorithms and introduce a new efficient precondition

Introduction: Inequality of income distribution is one of the socio-economic issues of developing countries, including Iran. One of the proposed solutions to deal with this phenomenon is to reduce educational inequality. The purpose of this study is

BACKGROUND: Comorbidities are one of the major factors in the failure of treatment of chronic obsessive-compulsive disorder (OCD). The present study examines the efficacy of cognitive restructuring (CR) and progressive muscle relaxation (PMR) on depr

Control of the effective local hyperfine fields in a conjugated polymer, poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylenevinylene] (MEHPPV), by isotopic engineering is reported. These fields, evident as a frequency-independent line broadening mechan

In this paper we study the problem of computing the geodesic center of a simple polygon when the available workspace is limited. For an $n$-vertex simple polygon, we give a time-space trade-off algorithm that finds the geodesic center in $O(T(n, s) \

Antiferromagnetically coupled S=1/2 spins on an isotropic triangular lattice is the paradigm of frustrated quantum magnetism, but structurally ideal realizations are rare. Here we investigate NaYbO$_2$, which hosts an ideal triangular lattice of $J_{
