BACKGROUND Reduced heart rate variability has been identified as an important prognostic factor after myocardial infarction. This factor is thought to reflect an imbalance between sympathetic and parasympathetic activity, which may lead to unfavourable loading conditions and thus promote left ventricular dilatation. PATIENTS AND METHODS 298 patients in a multicentre clinical trial were random...

Abstract. For wastewater discharged into one branch of a narrow estuary, the resulting maximum concentration or temperature can vary markedly depending upon the proximity of the discharge site to the branching and upon how the rate of discharge is adjusted. Explicit formulae are derived for the optimal discharge rate to minimize the maximum concentration or temperature experienced in the estuar...

INTRODUCTION Since children neither comprehended nor contribute to the decision, discharge against medical advice is a challenge of health care systems in the world. Therefore, the current study was designed to determine the rate and causes of discharge against medical advice. METHODS This descriptive cross-sectional study was done by reviewing the medical records by census method. Data was a...

We compared the effects of common excitatory and inhibitory inputs on motoneuron synchronization by simulating synaptic inputs with injected current transients. We elicited repetitive discharge in hypoglossal motoneurons recorded in slices of rat brain stem using a combination of a suprathreshold injected current step with superimposed noise to mimic the synaptic drive likely to occur during ph...

The discharge of granular material from a hopper subject to vertical sinusoidal oscillations was investigated using experiments and discrete element computer simulations. With the hopper exit closed, side-wall convection cells are observed, oriented such that particles move up along the inclined walls of the hopper and down at the center line. The convection cells are a result of the granular b...

The proper orthogonal decomposition method was applied to develop an efficient, reduced order electrochemical–thermal model for a lithium-ion cell. This model was validated for discharge simulations over a wide range of C rates and various cooling conditions of the cell. The reduced order model agrees well with the COMSOL model, a commercial finite element method solver, and requires 7 times le...

Abstract Zinc–air batteries have gained significant attention as safe battery alternatives, with high theoretical energy densities and a abundance of their constituent materials. However, barriers to widespread adoption include the need improve cycling lifetime, well stability avoiding degradation mechanisms such zinc dendrite growth hydrogen-producing side reactions. X-ray computed tomography ...

The discharge characteristics of type B left atrial receptors were analyzed during alterations in heart rate. Recordings were made from single-fiber preparations of the left cervical vagus of pentobarbital-anesthetized, open-chest dogs. The heart was paced following a sinoatrial crush at frequencies ranging from 60 to 240 beats/min. Left atrial transmural pressure was varied at each heart rate ...

BACKGROUND Despite growing consensus on nosology and epidemiology of bipolar disorder (BD) in minors, differences remain. We contribute to this discussion by measuring long-term trends in the inpatient discharge rates of BD in minors. METHODS Nationwide German inpatient discharge diagnoses of BD and other related psychiatric disorders were mapped between 2008 and 2013 using registry data from...
