In low nanomolar concentrations, NO (nitric oxide) functions as a transmitter in brain and other tissues, whereas near-micromolar NO concentrations are associated with toxicity and cell death. Control of the NO concentration, therefore, is critical for proper brain function, but, although its synthesis pathway is well-characterized, the major route of breakdown of NO in brain is unclear. Previo...

The importance of energy preservation in wireless sensor networks is long established, and a number of maximum lifetime routing schemes exist in the literature. Many of the existing online routing schemes are based on the use of some edge-weight functions, but those schemes exhibit diverse performances in terms of the obtained lifetime results. The major contribution of the present work is to c...

This paper generalizes the model of Becker, Grossman, and Murphy (1994) to the multivariate case. The multivariate model generates Frisch demand functions where current consumption is related to prices of all goods, and lagged and future consumption of all goods. The theoretical restrictions are that current price effects (holding lagged and future consumption constant) are negative definite, a...

The profession has been longing for closed-form solutions to consumption functions under uncertainty and borrowing constraints. This paper proposes an analytical approach to solving general-equilibrium bu¤er-stock saving models with both idiosyncratic and aggregate uncertainties as well as liquidity constraints. It is shown analytically that an individual’s optimal consumption plan follows the ...

In studying individual consumption behavior, an important issue is the analysis of the relation between commodity expenditure and income (or total expenditure). In this paper we firstly review the more recent theoretical and empirical literature attempting to: (i) derive theory-consistent demand systems models which are able to account for empirically observed non-linearities in total expenditu...

we present a collocation method to obtain the approximate solutionof troesch's problem which arises in the confinement of a plasmacolumn by radiation pressure and applied physics. by using thechristov rational functions and collocation points, this methodtransforms troesch's problem into a system of nonlinear algebraicequations. the rate of convergence is shown to be exponential. then...

This study compared three methods of normalizing demand functions to allow comparison of demand for different commodities and examined how varying reinforcer magnitudes affected these analyses. Hens responded under fixed-ratio schedules in 40-min sessions with response requirement doubling each session and with 2-s, 8-s, and 12-s access to wheat. Over the smaller fixed ratios overall response r...
