A two-dimensional sagittally symmetric human-body model was established to simulate an optimal MAG Drills trajectory for manual material handling tasks.Nonlinear control techniques and genetic algorithms were utilized in the optimizations to explore optimal lifting patterns.The simulation results were then compared with the experimental data.Since

Objective The Yale Global Tic Severity Scale (YGTSS) is the most commonly used clinician-rated evaluation tool for Tourette syndrome (TS), with established reliability and validity.This study aims to determine whether the YGTSS is a valid parent-reported assessment in the TS population.Design A prospective cohort study.Setting A major medical centr

This paper argues that we may read the images from the Lucy Lloyd archive of ancient Khoe and San symbols, drawings Aluminum Carryout / Containers and pictograms in a special way that offers an intellectual seriousness to these collaborative picture-word creations that attempted to hold certain faunal and floral knowledge and descriptions from the

Pulsars, especially X-ray pulsars detectable Aluminum Carryout / Containers for small-size detectors, are highly accurate natural clocks suggesting potential applications such as interplanetary navigation control.Due to various complex cosmic background noise, the original pulsar signals, namely photon sequences, observed by detectors have low sign

Extrafloral structures are supposed to have evolved to protect flowers from harsh physical environments but might have effects on pollination.Overlapping leaves cover flowers in Eriophyton wallichii, an alpine perennial endemic to the Himalaya-Hengduan Mountains.In previous study, it has showed that these extrafloral leaves can protect interior flo
