An introduction to the key topics and challenges in Botnet, buffer overflow vulnerability, privacy-preserving and others.

Three policies, namely optimal repacking, least load routing, and Bernoulli splitting, are considered for dynamic resource allocation in load sharing networks with standard Erlang type statistics. Large deviations principles are established for the three policies in a simple network of three consumer types and two resource locations and are used to identify the network overflow exponents. The o...

The problem of finding the minimum cost multi-commodity flow in an undirected and complete network is studied when the link costs are piecewise linear and convex. The arc-path model and overflow model are presented to formulate the problem. The results suggest that the new overflow model outperforms the classical arc-path model for this problem. The classical revised simplex, Frank and Wolf and...

We investigate the sensitivity of a coarse resolution coupled climate model to the representation of the overflows over the Greenland–Scotland ridge. This class of models suffers from a poor representation of the water mass exchange between the Nordic Seas and the North Atlantic, a crucial part of the large-scale oceanic circulation. We revisit the explicit representation of the overflows using...

The release of endogenous noradrenaline and its deaminated metabolite dihydroxyphenylglycol in the myocardium have been studied in the isolated perfused heart of the rat subjected to three models of energy depletion: ischemia, anoxia, and cyanide intoxication. Anoxia and cyanide intoxication were combined with substrate deficiency at constant perfusion flow. All three energy-depleting procedure...

The pharmacological properties and subtypes of prostanoid receptors involved in the prejunctional modulation of [(3)H]norepinephrine release from sympathetic neurons were studied using isolated rabbit aorta. Rings preincubated with [(3)H]norepinephrine were washed with physiological salt solution that contained cocaine plus corticosterone, uptake(1) and uptake(2) inhibitors, respectively, and r...

Lobeline interacts with the dopamine transporter and vesicular monoamine transporter, presynaptic proteins involved in dopamine storage and release. This study used rodent models to assess lobeline-induced inhibition of the neurochemical and behavioral effects of amphetamine. Rat striatal slices were preloaded with [(3)H]dopamine and superfused with lobeline for 30 min, and then with d-amphetam...

I) Goals and Purpose Software developers use Stack Overflow to post questions and answers related to programming and computer science problems they need to solve. Questions such as seeking input on some efficient and time-saving methods of coding a particular program, getting help on solving various bottlenecks in coding are commonly seen. When users submit questions on Stack Overflow they need...

Structural simplification of N-n-alkylnicotinium analogs, antagonists at neuronal nicotinic acetylcholine receptors (nAChRs), was achieved by removal of the N-methylpyrrolidino moiety affording N-n-alkylpyridinium analogs with carbon chain lengths of C1 to C20. N-n-Alkylpyridinium analog inhibition of [3H]nicotine and [3H]methyllycaconitine binding to rat brain membranes assessed interaction wi...

Interval analysis seeks static lower and upper bounds on the values of program variables. These bounds are useful, especially for inferring invariants to prove buffer overflow checks. In practice, however, intervals by themselves are often inadequate as invariants due to the lack of relational information among program variables. In this paper, we present a technique for deriving symbolic bound...
