Cyclization of a pentapyrrane with two terminal β-linked pyrroles afforded a dihydrosapphyrin isomer (1) with the pyrroles linked in a unique β,α–α,β mode, which was rather reactive, and thus it ...

We introduce the concept of a control contraction metric, extending contraction analysis to constructive nonlinear control design. We derive sufficient conditions for exponential stabilizability of ...

Ouabain added to the perfusate (2.8 x 10 -7 M final concentration) promptly increased the force of contraction and oxygen consumption of the hearts. These events appeared to occur simultaneously.

Background Endothelium-derived substances and the renin-angiotensin system are important regulators of vascular tone. This study was designed to evaluate the effects of age and hypertension on vascul ...

Like the fissionable atom, punctuation marks are wee items capable of causing a tremendous release of energy. Passionate ...

The contraction coefficient of stochastic mappings between full matrix algebras is introduced with respect to a generalized relative entropy labeled by an operator convex function g.

In the high field magnet program at Lawrence Berkeley National Laboratory, accelerator magnet prototypes are designed with epoxy impregnated niobium-tin and niobium-titanium superconductor. Accurate ...

Deflation is the decline in prices for goods and services that happens when the inflation rate dips below 0%.

Inspired by the passionate response to the semicolon’s supposed decline, this quiz invites you to test – and perhaps rediscover – your grasp of English grammar, from the basics to the ...

It is often observed that polymer patterns fabricated by capillary force lithography (CFL) are not identical, position-dependent even in one sample. The drawback has not been successfully explained so ...

Skeletal muscle force production following repetitive contractions is preferentially reduced when muscle is evaluated with low-frequency stimulation. This selective impairment in force generation is ...
