Eccentric types of endurance exercise are an acknowledged alternative to conventional concentric types of exercise rehabilitation for the cardiac patient, because they reduce cardiorespiratory strain due to a lower metabolic cost of producing an equivalent mechanical output. The former contention has not been tested in a power- and work-matched situation of interval-type exercise under identica...

Your muscles can contract in different ways: when you walk upstairs, the at fronts of your thighs shorten (concentric contraction), whereas downstairs, they lengthen (eccentric contraction). Concentric contractions require more oxygen and thus make burn calories. Eccentric are easier but break parts muscle feel sore for several days. If repeat eccentric exercises, however, will probably get big...

Fedirko, Nataliya, Nataliya Svichar, and Mitchell Chesler. Fabrication and use of high-speed, concentric H and Ca -selective microelectrodes suitable for in vitro extracellular recording. J Neurophysiol 96: 919–924, 2006; doi:10.1152/jn.00258.2006. Ion-selective microelectrodes (ISMs) have been used extensively in neurophysiological studies. ISMs selective for H and Ca are notable for their sen...

Concentric mosaic offers a quick solution for the construction and navigation of a virtual environment. However, the associated huge amount of data presents a heavy burden for its application. In this paper, we propose the rebinning of slits (ROSS) approach for the compression of concentric mosaic. The proposed scheme decorrelates the 3D concentric mosaic data set by rebinning the vertical slit...

Concentric mosaics have the ability to quickly capture a complete 3D view of a realistic environment and to enable a user to wander freely in the environment. However, the data amount of the concentric mosaics is huge. In this paper, we propose an algorithm to compress the concentric mosaic image array through motion compensation and residue coding, which we called reference block codec (RBC). ...

Baló's concentric sclerosis is a primary inflammatory central nervous system demyelinating disease that is considered a rare, radiographically and pathologically distinct variant of multiple sclerosis. Baló's concentric sclerosis is characterized by alternating rings of demyelinated and myelinated axons, and it is most frequently diagnosed postmortem by autopsy or, more recently, by magnetic re...

Introduction: Lunar concentric craters represent an anomalous type of impact structures on the Moon [1]. The concentric crater Archytas G in mare Frigoris has first been catalogued as a concentric crater in [2]. According to Fig. 1, it is located on top of a large lunar intrusive dome, termed Ar1 in [3]. The dome Ar1 is the only lunar dome known to date with a concentric crater on its surface. ...

We propose an ultracompact parallel label-free biosensor based on concentric silicon-on-insulator microring resonators. Our numerical studies show that the proposed biosensor offers higher sensitivity and a larger detection area than conventional single-ring-based sensors. We analyze the detection sensitivity of the DNA hybridization by immobilizing the probe on top of the double concentric rin...
