Background: Aging often results in thoracic kyphosis and adverse postural changes. This may interfere with physiologic activity of paraspinal muscles. Few styles of spinal orthosis have been already used to reduce thoracic kyphosis. This paper describes the development of a novel orthosis, which is designed based on the anatomy of the back muscles. This novel orthosis may potentiate muscle acti...

Abstract The formation and main features of the fully nonlinear structure in a six-component dusty plasma system have been investigated using Sagdeev potential approach. By means pseudo-potential technique, fluid equations describing were diminished into single differential equation, called energy equation modified by presenting parameters addition components. For certain values configurational...

let $pounds$ be the category of locally compact abelian groups and $a,cin pounds$. in this paper, we define component extensions of $a$ by $c$ and show that the set of all component extensions of $a$ by $c$ forms a subgroup of $ext(c,a)$ whenever $a$ is a connected group. we establish conditions under which the component extensions split and determine lca groups which are component projective. ...

The heteroleptic six-component double slider-on-deck system DS3 exhibits tight coupling of motional speed two distinct nano-circular sliders (k298 = 77 and 41 kHz) despite a 2.2 nm sepa­ration. In comparison, the single in DS1 DS2 move at vastly diffe­rent 1.1 vs. 350 kHz). Synchro­nization motions remains even when one slows movement faster slider using small molecular brake pads. contrast to ...
