We present lookahead widening, a novel technique for using existing widening and narrowing operators to improve the precision of static analysis. This technique is both self-contained and fully-automatic in the sense that it does not rely on separate analyzes or human involvement. We show how to integrate lookahead widening into existing analyzers with minimal effort. Experimental results indic...

We propose a method to gradually expand the moves to consider at the nodes of game search trees. The algorithm begins with an iterative deepening search using the minimal set of moves, and if the search does not succeed, iteratively widens the set of possible moves, performing a complete iterative deepening search after each widening. When designing carefully the different sets of possible move...

1. Understand the epidemiology of pediatric poisonings and explain how developmental milestones influence behavior that may lead to a poisoning exposure. 2. Perform a focused toxicologic physical examination and describe the various toxidromes. 3. Explain the primary acid-base disturbance in salicylate toxicity. 4. Determine which patient requires treatment after acute acetaminophen ingestion. ...

CONTEXT Desvenlafaxine is used to treat major depression. Desvenlafaxine is also the active metabolite of venlafaxine. Venlafaxine overdose can cause serotonin toxicity, seizures and cardiovascular effects, but there is limited information on desvenlafaxine overdose. OBJECTIVE We aimed at investigating the clinical effects and complications from desvenlafaxine overdose. MATERIALS AND METHOD...

BACKGROUND Abnormal values of the spatial angle between the directions of ventricular depolarization and repolarization (QRS-T) reflect the action potential inhomogeneities and predict cardiac events and mortality in various patient groups. The study was designed to (i) compare QRS-T in haemodialysis (HD) patients and healthy subjects, (ii) assess the influence of HD on QRS-T and (iii) evaluate...

AIMS The independent clinical correlates and prognostic impact of QRS prolongation in heart failure (HF) with reduced and preserved ejection fraction (EF) are poorly understood. The rationale for cardiac resynchronization therapy (CRT) in preserved EF is unknown. The aim was to determine the prevalence of, correlates with, and prognostic impact of QRS prolongation in HF with reduced and preserv...
