Marginal sea overflows and the overlying upper ocean are coupled in the vertical by two distinct mechanisms— by an interfacial mass flux from the upper ocean to the overflow layer that accompanies entrainment and by a divergent eddy flux associated with baroclinic instability. Because both mechanisms tend to be localized in space, the resulting upper ocean circulation can be characterized as a ...

The extracellular dopamine level is regulated not only by synaptic inputs to dopamine neurons but also by local mechanisms surrounding dopaminergic terminals. However, much remains to be investigated for the latter mechanism. Thromboxane A(2) is one of the cyclooxygenase products derived from arachidonic acid, and acts on its cognate G protein-coupled receptor [thromboxane receptor (TP)]. We sh...

HEALERS is a practical, high-performance toolkit that can enhance the robustness and security of existing applications. For any shared library, it can find all functions defined in that library and automatically derives properties for those functions. Through automated faultinjection experiments, it can detect arguments that cause the library to crash and derive safe argument types for each fun...

Online programming discussion platforms such as Stack Overflow serve as a rich source of information for software developers. Available information include vibrant discussions and oftentimes ready-to-use code snippets. Previous research identified Stack Overflow as one of the most important information sources developers rely on. Anecdotes report that software developers copy and paste code sni...

The accumulation of endogenous catecholamines within the extracellular space of the ischemic myocardium has been studied in the isolated perfused (Langendorff) heart of the rat subjected to various periods of complete ischemia, with subsequent collection of the reperfusate. Catecholamines and deaminated metabolites were measured by radioenzymatic methods, or high pressure liquid chromatography....

The sympathetic nervous system and renin-angiotensin system are both thought to contribute to the development and maintenance of hypertension in experimental models such as the spontaneously hypertensive rat (SHR). We demonstrated that periarterial nerve stimulation (NS) increased the perfusion pressure (PP) and neuropeptide Y (NPY) overflow from perfused mesenteric arterial beds of SHRs at 4-6...

Buffer overflow attacks continue to be a major security problem and detecting attacks of this nature is therefore crucial to network security. Signature based network based intrusion detection systems (NIDS) compare network traffic to signatures modelling suspicious or attack traffic to detect network attacks. Since detection is based on pattern matching, a signature modelling the attack must e...

Using a perfused innervated rat heart model, we studied the sex difference in the sympathetic nerve stimulation-induced norepinephrine release and its presynaptic alpha 2-adrenergic inhibition in normoxic and ischemic conditions. During normoxic perfusion, the alpha 2-adrenoceptor antagonist rauwolscine resulted in a higher overflow of norepinephrine during nerve stimulation in females than in ...

A soft sensor approach is described for controlling metabolic overflow from mixed-acid fermentation and glucose overflow metabolism in a fed-batch cultivation for production of recombinant green fluorescence protein (GFP) in Escherichia coli. The hardware part of the sensor consisted of a near-infrared in situ probe that monitored the E. coli biomass and an HPLC analyzer equipped with a filtrat...
