Single-Atom Materials The single-atom materials (SAMs) have been explored a lot in recent years, but there are still many barriers needed to overcome, which hold back the practical use of SAM. In article number 2000051 by Dingsheng Wang and co-workers, main opportunities discussed, aiming provide guideline for research on next step push acknowledgement SAMs higher level.

in reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. in this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...

the objective of this study was to determine the effects of grasp conditions (types of grasp, grasp width, glove and types of coupling) on maximal pushing force (mpf) and required pinch force (rpf) during snap fit assembly. the results indicated that the type of grasp, the type of coupling and wearing gloves have significant (p

[Purpose] The purpose of this study was to examine the effect of lumbar stability exercises on chronic low back pain by using sling exercise and push-ups. [Subjects] Thirty adult subjects with chronic back pain participated, with 10 adults being assigned to each of 3 exercise groups: general physical therapy (PT), lumbar stability using sling exercises (Sling Ex), and sling exercise plus push-u...

To a B-coring and a (B, A)-bimodule that is finitely generated and projective as a right A-module an A-coring is associated. This new coring is termed a base ring extension of a coring by a module. We study how the properties of a bimodule such as separability and the Frobenius properties are reflected in the induced base ring extension coring. Any bimodule that is finitely generated and projec...

The first purpose of the study was to investigate biomechanical characteristics of eight different Taekwondo kicks and to categorize them by the newly defined index of coordination of hip and knee joint motions. The second purpose was to investigate the effect of the rhythmic hop (habitually performed by athletes in Taekwondo sparring) in order to find whether rhythmic hop improves kicking perf...

Objective. To examine the effects of a 12-week Hatha yoga intervention on cardiorespiratory endurance, muscular strength and endurance, and flexibility in Chinese adults. Methods. 173 adults (aged 52.0 ± 7.5 years) were assigned to either the yoga intervention group (n = 87) or the waitlist control group (n = 86). 19 dropped out from the study. Primary outcomes were changes in cardiorespiratory...

This study aimed to investigate the effects of different freehand exercises on the electromyographic (EMG) activity of Triceps Brachii (TB) and Pectoralis Major (PM) muscles. Ten healthy men (21.25 ± 2.09 years) performed 1 repetition of four different freehand exercises. The maximum voluntary contraction (MVC) was recorded with the help of biograph infinity software (EMG). Surface ElectroMyoGr...

Due to the stochastic uncertainties in ramp area aircraft trajectories, the optimization of push back time windows has to account for randomness associated with the trajectories. This paper formulates a mixed integer linear program for computing the optimal chanceconstrained aircraft push back time windows. The solutions are chance-constrained because they allow for a non-zero but bounded proba...

ABSTRACT An analytical model of a pandemic, initiated by a single focus and spreading over a continent, is developed using foci as the smallest units of disease and fields as the smallest units of host. A few generalizing assumptions lead to a parameter-sparse model that may answer general questions on pandemics in a qualitative manner. For pandemic spread of disease during one season, a 'withi...
