To plan for any future rescue of personnel in a disabled and pressurized submarine, the US Navy needs a method for predicting risk of decompression sickness under possible scenarios for crew recovery. Such scenarios include direct ascent from compressed air exposures with risks too high for ethical human experiments. Animal data, however, with their extensive range of exposure pressures and inc...

GORDON, ALLEN R., AND MARION J. SIEGMAN. Mechanical properties of smooth muscle. I. Length-tension and force-velocity relations. Am. J. Physiol. 221 (5) : 1243-1249. 1971 .-The length-tension and force-velocity relationships of rabbit taenia coli were studied at 22 C. The absence of spontaneous mechanical activity at this temperature was confirmed by test applications of epinephrine. The muscle...

Consider Hill’s operator Q = − d2 dx2 + q(x) in which the potential q(x) is an almost surely continuous and rotation invariant Gaussian process on the circle x ∈ [0, 1). Viewing the classical Riccati map as a change of measure, we establish functional integral formulas for the probability density function of the ground state energy and also determine the density’s shape.

In this paper we investigate numerically the following Hill’s equation x + (a + bq(t))x = 0 where q(t) = cos t + cos √

In this paper, we generalize the models used by MacKay [1] in his analysis of evolutionary strategies that are based on sexual, rather than asexual, reproduction methods. This analysis can contribute to the understanding of the relative power of genetic algorithms over search methods based upon stochastic hill-climbing, e.g. [2], [3].

MOTIVATION Realistic simulation of the kinetic properties of metabolic pathways requires rate equations to be expressed in reversible form, because substrate and product elasticities are drastically different in reversible and irreversible reactions. This presents no special problem for reactions that follow reversible Michaelis-Menten kinetics, but for enzymes showing cooperative kinetics the ...

introduction: spatial variation of soil properties is significantly influenced by numerous environmental factors such as landscape features, including position, topography, slope gradient and aspect, parent material, climate and vegetation. soil properties vary spatially in south- and north-facing hill slopes. this factor (different slope aspects) can affect the distribution of soil organic mat...

conclusions glenohumeral joint reduction with reconstruction of the humeral head seems to be possible even in a neglected locked posterior shoulder fracture-dislocation. if the depressed osteochondral fragment is still spheric, signs of the avascular necrosis are absent on ct, and mal:union: of the fragment has occurred, it is quite possible to reconstruct the head. although results of the case...

We find pairs of solutions to a differential equation which is obtained as a special limit of a generalized spheroidal wave equation (this is also known as confluent Heun equation). One solution in each pair is given by a series of hypergeometric functions and converges for any finite value of the independent variable z, while the other is given by a series of modified Bessel functions and conv...
