Conflict Identification in Aspect-Oriented Requirements Engineering (AORE) is an integral step toward resolving conflicting dependencies between requirements at an early stage of the software development. However, to date there has been no work supporting detection of conflicts in a large set of textual requirements without converting texts into an alternative representation (such as models or ...

We consider the application of EA modulators to analog-todigital conversion. We have previously shown that for constant input signals, optimal nonlinear decoding can achieve large gains in signal-to-noise ratio (SNR) over linear decoding. In this paper we show a similar result for band-limited input signals. The new nonlinear decoding algorithm is based on projections onto convex sets (POCS), a...

OBJECTIVE The aim of this study was to determine in a randomized, double-blind, placebo-controlled clinical trial the effects of typified propolis and chlorhexidine rinses on salivary levels of mutans streptococci (MS) and lactobacilli (LACT). METHODS One hundred patients were screened for salivary levels of MS >100,000 CFUs/mL of saliva. All patients presented with at least one cavitated dec...

PURPOSE To report the incidence of threshold retinopathy of prematurity (ROP) in very low birth weight premature infants from three neonatal intensive care units (NICUs) before and after implementation of a physiologic reduced oxygen protocol (PROP). METHODS PROSPECTIVE, OBSERVATIONAL STUDY OF DATA FROM THREE NICUS: Cedars-Sinai Medical Center (CSMC), Los Angeles; Good Samaritan Hospital (GSH...

Model-free deep reinforcement learning (RL) methods have been successful in a wide variety of simulated domains. However, a major obstacle facing deep RL in the real world is the high sample complexity of such methods. Unbiased batch policy-gradient methods offer stable learning, but at the cost of high variance, which often requires large batches, while TD-style methods, such as off-policy act...

ABSTRACT Three 2'-aminochalcone derivatives (E)-1-(2-aminophenyl)-3-(4-hydroxyphenyl)prop-2-en-1-one, (E)-1-(2-aminophenyl)-3-(3,4-dihydroxyphenyl)prop-2-en-1-one, and (E)-1-(2-amino-4,5-dimethoxyphenyl)-3-(4-methoxyphenyl)prop-2-en-1-one, have been synthesized, characterized, and tested in vitro in order to assess their antioxidant activity. All compounds were characterized on the basis of 1H ...

BACKGROUND Accurate determination of pulmonary vascular resistance (PVR) is an important component in the evaluation and treatment of pediatric patients with pulmonary hypertension. We developed a novel technique, based on the concept of flow propagation, to estimate PVR noninvasively. The hypothesis is that changes in PVR cause changes in the velocity propagation (Vel(prop)) within the main pu...

Experimental studies are presented in this paper on the stability of structural steel props. Three full-scale prop specimens with various geometric properties were constructed and tested statically and elastically in the lab, in order to obtain the elastic strength of the props. The total unsupported length is 6 m for the three props. The outer and inner diameters are 150 mm and 140 mm, 138 mm ...

Adrenergic responses are crucial for hypoglycemic recovery. Epinephrine increases glucose production, lipolysis, and peripheral insulin resistance as well as blood flow and glucose delivery. Sympathetic activation causes vasoconstriction and reduces glucose delivery. To determine the effects of alpha- and beta-adrenergic activity on muscle glucose uptake during hypoglycemia, we studied forearm ...
