(American Physical Society, 2019)We show that the dynamics of a driven quantum system weakly coupled to a finite reservoir can be approximated by a sequence of Landau-Zener transitions if the level spacing of the reservoir is large enough. This approximation ...

Does adding inventory increase sales? Evidence of a scarcity effect in U.S. Automobile dealerships (INFORMS Inst.for Operations Res.and the Management Sciences, 2019)Copyright: © 2018 INFORMSWhat is the relationship between inventory and sales? Clearly, inventory could increase sales: expanding inventory creates more choice (options, colors, etc.) and might signal a popular/desirable ...

(Elsevier Ltd, 2019)We study the determinants of sudden stops in capital flows to emerging markets. Using gross international asset and liability flows (from the point of view of domestic residents), we identify three types of situations: ...
-
(Frontiers Media S.A., 2019)Food intake in fish and mammals is orchestrated by hypothalamic crosstalk between orexigenic (food intake stimulation) and anorexigenic (food intake inhibition) signals. Some of these signals are released by peripheral ...
-
(Taylor and Francis Ltd., 2019)Atriplex includes species with multiple purposes such as biomass for energy production, for bioremediation of soils contaminated with metals, or soil conservation. In Chile, 29 Atriplex species have been recorded, of which ...
-
(Institution of Engineering and Technology, 2019)This work determined the potency of hexyl-ciprofloxacin molecules that reversibly interact with gold nanoparticles (AuNPs) passivated with 11-mercaptoundecanoic acid (MUA) on Escherichia coli cells. For this, partition of ...

Effect of dietary carbohydrate-to-protein ratio on gut microbiota in atlantic salmon (Salmo salar) (MDPI AG, 2019)Atlantic salmon (Salmo salar) is a carnivorous fish species whose productive performance tends to be suboptimal when fed low-cost carbohydrate rich meals. It is of interest to study the dynamics of gut microbiota communities ...
