We perform detailed muon spin rotation ($\ensuremath{\mu}\mathrm{SR}$) measurements in the classic antiferromagnet ${\mathrm{Fe}}_{2}{\mathrm{O}}_{3}$ and explain spectra by considering dynamic population dissociation of charge-neutral muon-polaron complexes. show that states ${\mathrm{Fe}}_{2}{\mathrm{O}}_{3}$, despite lacking signatures typical muonium centers nonmagnetic materials, have a si...

background: methicillin resistant staphylococcus aureus (mrsa) is a common major human pathogen that causes hospital-acquired infections. characterization and typing of the staphylococcal cassette chromosome has led to a better understanding of mrsa infection cycle in hospital. the meca-associated hypervariable region size classifies mrsa isolates that colonized in nasal carriers. objectives: t...

in this article differential transformation method (dtms) has been used to solve neutral functional-differential equations with proportional delays. the method can simply be applied to many linear and nonlinear problems and is capable of reducing the size of computational work while still providing the series solution with fast convergence rate. exact solutions can also be obtained from the kno...

Improvement in the optoelectronic performance of halide perovskite semiconductors requires identification and suppression nonradiative carrier trapping processes. The iodine interstitial has been established as a deep level defect implicated an active recombination center. We analyze quantum mechanics trapping. Fast irreversible electron capture by neutral is found. effective Huang–Rhys factor ...

For a long time transverse and longitudinal optical forces are used for non-contact noninvasive manipulation of small individual particles. The following question arises: What is the impact these on ensemble thousand particles in continuous media? aim this work to find analytical expression radiation force potential densities creating from laser pulse propagating dielectric media. This allows u...

A new Al(III) selective membrane based on 5-bromo(salicylidene-2-amino thiophenol) as a neutral carrier in a poly(vinyl chloride) (PVC) matrix is coated on platinum wire to determine trace amounts of Al(III) ion in various samples. The sensor exhibits a good response for Al(III) ion over a wide concentration range of 5.20 × 10-7 to 1.00 × 10-2 M  with Nernstian slope of 19...

In this study, the performance of fullerene (C20) and boron nitride cage (B12N12) as a sensing material for detection of proline was evaluated by density functional theory. For this purpose, the structures of proline, C20, B12N12 and the derived products from the proline adsorption on the surface of nanostructures were optimized geometrically. Then, IR and Frontier molecular orbital calculation...

Profiling of particle beams is one the most important diagnostic procedures for operating any kind accelerator. In this work, proton beam profilers, based on fluence measurements performed by recording changes carrier lifetime in Si material and scintillation intensity thin GaN layers, caused radiation induced defects emission centres, are presented. The penetrative (26 GeV/c) stopped (1.6 MeV)...

background staphylococcus aureus (sa) is frequently found on normal human skin and mucous membranes. methicilline resistance s. aureus (mrsa) strains have spread in many hospital isolates world wide since 1970s. hospital personnel tend to have higher colonization rates than the general population. colonized residents and personnel are sources for dissemination of organism. materials and methods...
