Numerous studies have documented the mechanisms that regulate intracellular pH (pH(i)) in hippocampal neurons in response to an acid load. Here, we studied the response of pH(i) to depolarization in cultured hippocampal neurons. Elevation of external K+ (6-30 mm) elicited an acid transient followed by a large net alkaline shift. Similar responses were observed in acutely dissociated hippocampal...

The direct interaction approximation (DIA), due to Kraichnan [1], was the first field-theoretical approach to the theory of turbulence. Formulated in terms of the Dyson equation, the DIA is characterized as the lowest-order approximation that includes nonlinear corrections to the propagator for the mode v(k,a>). It was shown [1] that, in the inertial range, the DIA gives the energy spectrum is ...

Previous dialogue systems have focussed on dia. logues betwe(:n two agents. Many ~q)plications, however, require conversations between several l)articipants. This paper extends speech act deftnit ions to handle mult i -agent conversations, based on a model of mult i -agent belief a t t r ibu t ion with some unique properties. Our approach has |,lie advantage of captur ing a lnnnlmr of interesti...

Anorexia nervosa is an eating disorder associated with severe weight loss as a consequence of voluntary food intake avoidance. Animal models such as dehydration-induced anorexia (DIA) mimic core features of the disorder, including voluntary reduction in food intake, which compromises the supply of energy to the brain. Glial cells, the major population of nerve cells in the central nervous syste...

e i ackground & Aims: Two advanced cytologic techniques or detecting aneuploidy— digital image analysis (DIA) and flurescence in situ hybridization (FISH)— have recently been deeloped to help identify malignant pancreatobiliary strictures. he aim of this study was to assess the clinical utility of ytology, DIA, and FISH for the identification of malignant ancreatobiliary strictures. Methods: Br...

Atrazine is an agricultural herbicide used in large quantities and consequently companied with its two degradation products, deethylatrazine (DEA), and deisopropylatrazine (DIA), are commonly detected in groundwater and surface water. The retention of these compounds in vadose zone is highly related to their adsorption to soils. Laboratory studies were conducted to determine the sorption behavi...

In statistical mechanics, the canonical partition function [Formula: see text] can be used to compute equilibrium properties of a physical system. Calculating [Formula: see text] however, is in general computationally intractable, since the computation scales exponentially with the number of particles [Formula: see text] in the system. A commonly used method for approximating equilibrium proper...

| Designing distributed multimedia applications raises temporal and spatial synchronization issues related to processing, transport, storage, retrieval and presentation of data, sound, still images and video. Within this framework , the paper aims to deene a general-purpose multime-dia synchronization mechanism, known as the conditional delivery mechanism capable of addressing both intra-and in...
