h-CMD: An efficient hybrid fast centroid and quasi-centroid molecular dynamics method for the simulation of vibrational spectra.

Developing efficient path integral (PI) methods for atomistic simulations of vibrational spectra in heterogeneous condensed phases and interfaces has long been a challenging task. Here, we present the h-CMD method, short for hybrid centroid molecular dynamics, which combines the recently introduced fast quasi-CMD (f-QCMD) method with fast CMD (f-CMD). In this scheme, molecules that are believed to suffer more seriously from the curvature problem of CMD, e.

Investigation of high-risk areas of electrical damage in the province of tehran.

Electrical burns are an uncommon type of burn that can cause serious disabilities and mortality. This study aims to provide preventive strategies to investigate high-risk areas of electrical damage in Tehran Province. This is a descriptive cross-sectional study performed on patients with electrical burns referred to Shahid Motahari Educational and Medical Center during 2015-2017.

Microplastic footprints in sharks and rays: First assessment of microplastic pollution in two cartilaginous fishes, hardnose shark and whitespotted whipray.

Microplastic (MP) pollution is an emerging environmental problem worldwide and has caused widespread concern both in terrestrial and aquatic ecosystems due to their potential impacts on the human health, and health of aquatic organisms and the environment. Little is known about the exposure of top marine predators to MP contamination (debris 0.1μm - <5mm, also called MPs).

A novel methodology for assessing resources and environmental carrying capacity with emphasis on ecosystem services: A multi-disciplinary approach to sustainable urban planning.

Due to increased human activities, urban areas face challenges in maintaining their environment and natural resources in support of development. As a result, it is necessary to plan according to the availability of resources and the state of the environment to achieve sustainable development. For this purpose, Carrying capacity (CC) can be used to assess the sustainability of cities as complex Social-Ecological Systems (SES).
