PURPOSE A large body of literature has indicated vowel space area expansion in infant-directed (ID) speech compared with adult-directed (AD) speech, which may promote language acquisition. The current study tested whether this expansion occurs in storybook speech read to infants at various points during their first 2 years of life. METHOD In 2 studies, mothers read a storybook containing targ...

background anthracyclines are important components of many chemotherapeutic protocols. the present study aimed to evaluate the repolarization changes in electrocardiography (ecg) which may predict drug induced arrhythmia. materials and methods in this cross-sectional study, the recorded ecgs were assessed for qt dispersion (qtd), qt corrected dispersion (qtcd), t peak to tend dispersion (tped),...

An economic model of the online advertising market is presented, focusing on the effect of ad fraud. In the model, the market is comprised of three classes of players: publishers, advertising networks, and advertisers. The central question is whether ad networks have an incentive to aggressively combat fraud. The main outcome of the model is to answer this question in the affirmative.

After baseline measurements of lung mechanics, effective air space diameter (EAD), and aerosol dispersion (AD), three dogs were exposed to two treatments of aerosolized papain (3 ml of a 4% solution), and measurements were repeated during a 28-wk follow-up period. EAD and AD were measured with boluses of 0.7-micrometer particles of di-2-ethylhexl sebacate, with Pen (i.e., volumetric bolus penet...

Abstract The presence of pulse front tilt (PFT), caused by angular dispersion (AD) in femtosecond laser pulses, could degrade the performance system and/or impact experimental yields. We present a single-shot diagnostic capable measuring AD x – y plane adopting an intensity mask. It can be applied to stretched making it ideal for diagnosing along amplification chain high-power system, and ultra...
