Programmers often consult an online Q&A forum such as Stack Overflow to learn new APIs. This paper presents an empirical study on the prevalence and severity of API misuse on Stack Overflow. To reduce manual assessment effort, we design Maple, an API usage mining approach that extracts patterns from over 380K Java repositories on GitHub and subsequently reports potential API usage violations in...

Since any personal computer has a limited range of integer values, therefore, it will result in an integer overflow when a program tries to compute a value larger than machine’s maximum value. We will discuss a workable algorithm that will be able to deal with any large numbers without getting an integer overflow.

The effect of ouabain on exocytotic and nonexocytotic norepinephrine release was investigated in perfused rat and guinea pig hearts. The overflow of endogenous norepinephrine and its neuronal metabolite 3,4-dihydroxyphenylethyleneglycol (DOPEG) was determined by high-pressure liquid chromatography. DOPEG served as the indicator of free axoplasmic norepinephrine concentrations. The overflow of t...

UNLABELLED α(2)-adrenoceptors (AR) lower central sympathetic output and peripheral catecholamine release, thereby protecting against sympathetic hyperactivity and hypertension. Norepinephrine re-uptake-transporter effectively (NET) removes norepinephrine from the synapse. Overflow to plasma will therefore not reflect release. Here we tested if inhibition of re-uptake allowed presynaptic α(2)AR ...

Context: The success of Stack Overflow and other community-based question-and-answer (Q&A) sites depends mainly on the will of their members to answer others’ questions. In fact, when formulating requests on Q&A sites, we are not simply seeking for information. Instead, we are also asking for other people’s help and feedback. Understanding the dynamics of the participation in Q&A communities is...

We performed experiments to determine the effects of acetylstrophanthidin (ACS) and ouabain on the adrenergic neuroeffector junction in dog saphenous veins. In quiescent strips incubated with 3H-norepinephrine (3H-NE), the drugs caused contraction and a progressive increase in overflow of 3H-NE and O-methylated metabolites; 3,4-dihydroxyphenylglycol (DOPEG) decreased. Tissue uptake of 3H-NE was...

Unintentional movement "overflow" between the hands or "mirror movements" are common in young children, but are generally regarded as indicative of developmental delay in older children. This study was designed to investigate mirror movements in a sample of 23 very poor readers, ages 11-13, with learning disabilities, and in a control group of 48 normal readers, matched for age, sex, and handed...

the probability of losing a customer in m/g/n/0 and gi/m/n/0 loss queuing systems withheterogeneous servers is minimized. the first system uses a queue discipline in which a customer who arriveswhen there are free servers chooses any one of them with equal probability, but is lost otherwise. providedthat the sum of the servers rates are fixed, loss probability in this system attains minimum val...
