A REVIEW OF STUDIES THAT USED B MODE ULTRASOUND TO ESTIMATE AGE-RELATED CHANGES IN ANTERIOR THIGH SKELETAL MUSCLE THICKNESS ACROSS THE ADULT LIFESPAN

A review of studies that used B mode ultrasound to estimate age-related changes in anterior thigh skeletal muscle thickness across the adult lifespan

Background: The purpose of this review was to synthesise and determine the age-related change per annum in muscle thickness of the anterior thigh across the adult lifespan.Methods: Electronic databases (PubMed, SPORTDiscus and MEDLINE) were searched for primary studies that were screened for eligibility.Results: Following screening against eligibil

Pseudorandom Number Generator Based on Three Kinds of Four-Wing Memristive Hyperchaotic System and Its Application in Image Encryption

In this paper, we propose a method to design the pseudorandom number generator (PRNG) using three kinds of four-wing memristive hyperchaotic systems (FWMHSs) with different dimensions as multientropy sources.The principle of this method is to obtain pseudorandom numbers with good randomness by coupling XOR operation on the three kinds of FWMHSs wit

Contribution of Voltage Support Function to Virtual Inertia Control Performance of Inverter-Based Resource in Frequency Stability

Inertia reduction due to inverter-based resource (IBR) penetration deteriorates power system stability, which can be addressed using virtual inertia (VI) control.There are two types of implementation methods for VI control: grid-following (GFL) and grid-forming (GFM).There is an apparent difference among them for the voltage regulation capability,

Airflow and dynamic circumference of abdomen and thorax for adults at varied continuous positive airway pressure ventilation settings and breath rates

Abstract Continuous positive airway pressure (CPAP) ventilation is a commonly prescribed respiratory therapy providing positive end-expiratory pressure (PEEP) to assist breathing and prevent airway collapse.Setting PEEP is highly debated and it is thus primarily titrated based on symptoms of excessive or insufficient support.However, titration peri
