A bstract This paper is an attempt to extend the recent understanding of Page curve for evaporating black holes more general systems coupled a heat bath. Although calculating von Neumann entropy by replica trick usually challenge, we have identified two solvable cases. For initial section curve, sum up perturbation series in system-bath coupling ? ; most interesting contribution order 2 s , whe...

BACKGROUND Validated measures to assess the severity of airway obstruction in patients with obstructive airway disease are limited. Changes in the pulse oximeter plethysmograph waveform represent fluctuations in arterial flow. Analysis of these fluctuations might be useful clinically if they represent physiologic perturbations resulting from airway obstruction. We tested the hypothesis that the...

A device which comprises three parts, electromotor, screw and cable, is proposed to suppress the vibration of a single-link flexible manipulator. The manipulator acted on jointly by the device and the load at manipulator’s end-effector is modeled as a cantilever beam with three concentrated loads at two end-points and midpoint. By taking the exserted length of the screw as control variable, the...

We examined two methods of generating a dose-response curve to the opioid receptor antagonist naloxone. In 15 healthy male subjects (18-25 years) plasma adrenocorticotropin (ACTH) responses to five doses of naloxone studied over 5 separate days were compared to plasma ACTH responses to five incremental doses of naloxone studied within a single session. There was a statistically significant posi...

In this study a multiaxial isokinetic dynamometer was used to measure strength during various upper-body isokinetic exertions. Ten male participants performed 7 different upper-body isokinetic exertions. In addition, to evaluate the effect of speed on strength, each participant performed sitting pull exertions at the speed of 0.026, 0.130, and 0.260 m/s. Average isokinetic strength increased fr...

A supersymmetric generalization of the Krichever map is used to construct algebro-geometric solutions to the various super KadomtsevPetviashvili (SKP) hierarchies. The geometric data required consist of a suitable algebraic supercurve of genus g (generally no t a super Riemann surface) with a distinguished point and local coordinates (z, 0) there, and a generic line bundle of degree g 1 with a ...

BACKGROUND/AIMS Single, global or unitary, indicators of test diagnostic performance have intuitive appeal for clinicians. The Q* index, the point in receiver operating characteristic (ROC) curve space closest to the ideal top left-hand corner and where test sensitivity and specificity are equal, is one such measure. METHODS Datasets from four pragmatic accuracy studies which examined the Min...

The first major advance in understanding expiratory flow limitation of the lungs came with the description of isovolume pressure-flow curves. These curves documented the existence of a volume-dependent limit to maximal expiratory flow and led directly to the description of the maximal expiratory flow-volume (MEFV) curve. Definitive modeling of flow limitation awaited the description of a locali...

1. Forced exhalations performed from volumes below total lung capacity, so-called partial expiratory flow-volume curves, are suggested to be more sensitive in detecting airways bronchoconstriction than maximal expiratory flow-volume curves begun at total lung capacity. 2. In eight healthy men both maximal and partial expiratory flow-volume curves were measured where breath was held at total lun...

Angiotensin II (Ang II) is known to enhance the vasoconstrictor response to norepinephrine (NE). In the present study, this interaction was investigated using isolated rabbit femoral artery rings mounted in tissue baths for the measurement of isometric contraction. Exposure to 3 x 10(-10) M Ang II caused a contraction that was less than 5% of the maximal response to NE. In the presence of Ang I...
