We study the Heisenberg antiferromagnet with single-ion anisotropy in two and three
dimensions and present self-consistent intuitive theory to show the Bose-Einstein condensation-…

Rationale: Patients who receive invasive mechanical ventilation (IMV) are usually exposed
to opioids as part of their sedation regimen. The rates of posthospital prescribing of opioids …

SARS-CoV-2 infection causing the novel coronavirus disease 2019 (COVID–19) has been
responsible for more than 2.8 million deaths and nearly 125 million infections worldwide as of …

Background Total joint replacement procedures are increasing in number because of population
aging and osteoarthritis development. Defined as a lack of physiological reserves and …

Purpose Restrictive fluid management strategies have been proposed to reduce complications
in liver transplant recipients. We conducted a systematic review to evaluate the effects of …

Objectives: Postoperative pulmonary complications increase mortality, length, and cost of
hospitalization. A better diaphragmatic strength may help face an increased work of breathing …

This study evaluated the role of physical and biological filter characteristics on the reduction
of MS2 bacteriophage in biosand filters (BSFs). Three full-scale concrete Version 10 BSFs, …

The bond operator representation of quantum S= 1 2 spins with the singlet state being projected
out is applied to investigate the isotropic spin-1 Heisenberg antiferromagnetic chain H=…

A bond operator representation of quantum S= 1 spins is developed along the same line to
the bond operator representation of quantum S= 1 2 spins. The two representations are then …

The bilayer spin-1/2 antiferromagnetic Heisenberg model is studied by the bond-operator
mean-field theory and perturbation theory. From both methods, the zero-temperature quantum …
