OBJECTIVE: The purpose of this study was to evaluate the effect of biologic characteristics
of platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) on proliferation and differentiation …

The guided Lamb wave is widely acknowledged as one of the most encouraging tools for
quantitative identification of damage in composite structures, and relevant research has been …

Sisal fibre is a promising reinforcement for use in composites on account of its low cost, low
density, high specific strength and modulus, no health risk, easy availability in some …

Activated sludge (AS) contains highly complex microbial communities. In this study, PCR-based
454 pyrosequencing was applied to investigate the bacterial communities of AS …

It is of increasing importance to explore new low‐cost and high‐activity electrocatalysts for
oxygen reduction reaction (ORR), which have had a substantial impact across a diverse …

The outbreak of the novel coronavirus disease (COVID‐19) quickly spread all over China
and to more than 20 other countries. Although the virus (severe acute respiratory syndrome …

The current status of research and development on laser shock processing of metals, also
known as laser peening, using Q-switched high power lasers is reviewed. The influence of …

The ubiquitin–proteasome system (UPS) and autophagy are two distinct and interacting
proteolytic systems. They play critical roles in cell survival under normal conditions and during …

We present observations and timing analyses of 68 millisecond pulsars (MSPs) comprising
the 15 yr data set of the North American Nanohertz Observatory for Gravitational Waves (…

Lamb waves are guided waves that propagate in thin plate or shell structures. There has
been a clear increase of interest in using Lamb waves for identifying structural damage, …
