We review lattice evidence for the vortex mechanism of quark confinement and study the influence of charged matter fields on the vortex distribution. 1 Review of the vortex mechanism of quark confinement In the early days of QCD some people argued that quarks are confined due to the non-abelian nature of gauge-fields leading to attraction between flux-lines. But the abelian U(1) lattice gauge t...

malnutrition is a common problem among nursing home residents and encompasses adverse outcomes. this study was conducted to determine malnutrition and urinary tract infections as well as antibiotic resistance of isolated bacteria at kahrisak nursing home in tehran city, capital of iran. nutritional status was determined by direct detection of kitchen, checking the menue of weekly foods, quality...

We simulate a finite system of N confined electrons with inclusion of the Darwin magnetic interaction in two and three dimensions. The lowest-energy states are located using the steepest descent quenching adapted for velocity dependent potentials. Below a critical density the ground state is a static Wigner lattice. For supercritical density the ground state has a nonzero kinetic energy. The cr...

The problem of projecting the energy confinement properties of future devices is a long-standing one in toroidal confinement research. While substantial progress has been made in characterizing the transport properties of tokamaks and stellarators, no definitive understanding of the mechanism(s) of cross-field transport has been achieved. Thus, we are not in a position to perform “firstprincipl...

We have observed spatial confinement of laser light in micrometer-sized random media. The optical confinement is attributed to the disorder-induced scattering and interference. Our experimental data suggest that coherent amplification of the scattered light enhances the interference effect and helps the spatial confinement. Using the finite-difference time-domain method, we simulate lasing with...

objectives this study is designed to investigate the epidemiology of home-related injuries in kashan, iran. background injury is one of the leading causes of morbidity and mortality in the world, and the home is one of the most common places for these types of injuries. patients and methods this investigation is a retrospective cross-sectional study on existing data from the data bank of the tr...

A new coronavirus has arisen, causing a pandemic of serious respiratory syndrome in humans. The COVID-19 major effect on human health, resulting abrupt lifestyle changes, social distances and loneliness at home. goal this study was to examine the immediate eating behavior physical activity among elderly population aged 60 years older. Data features senior citizens' profile, habits during lock-u...

Months after healing, a number of COVID-19 syndrome survivors are affected by both psychological and physical limitations. They mainly troubled with long-term fatigue, which is crucial aspect Long Covid syndrome. This paper aims to investigate the level persistency fatigue among from first wave pandemic in Western Liguria elucidate role gender, age, lifestyle. It also provides data scientific c...

Using Langevin dynamics simulations, we investigate the dynamics of a flexible polymer translocation into a confined area under a driving force through a nanopore. We choose an ellipsoidal shape for the confinement and consider the dependence of the asymmetry of the ellipsoid measured by the aspect ratio on the translocation time. Compared with an isotropic confinement (sphere), an anisotropic ...
