Clustering based physical-layer authentication in edge computing systems with asymmetric resources (MDPI AG, 2019)In this paper, we propose a clustering based physical-layer authentication scheme (CPAS) to overcome the drawback of traditional cipher-based authentication schemes that suffer from heavy costs and are limited by ...
-
(John Wiley and Sons Inc., 2019)The World Health Organization has estimated that, worldwide, cigarette smoking has caused more than 100 million deaths in the last century, a number that is expected to increase in the future. Understanding cigarette smoke ...
-
(MDPI AG, 2019)Extending the internet of things (IoT) networks to remote areas under extreme conditions or for serving sometimes unpredictable mobile applications has increased the need for satellite technology to provide effective ...
-
(MDPI AG, 2019)This research focused on obtaining eicosapentaenoic acid (EPA, 20:5 n-3) and docosahexaenoic acid (DHA, 22:6 n-3) (EPA+DHA) concentrates from refined commercial salmon oil (RCSO). Independent variables of the complexation ...
-
(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 ...
-
(Frontiers Media S.A., 2019)Recent evidence shows that most Patagonian glaciers are receding rapidly. Due to the lack of in situ long-term meteorological observations, the understanding of how glaciers are responding to changes in climate over this ...

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: ...
-
(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 ...
-
(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 ...
-
(Elsevier B.V., 2019)Trees’ growth responses to climate may depend on tree age and site conditions. In dioecious species, sex adds an extra level of complexity due to differential reproductive effort between the sexes and potentially sex-related ...
-
(EDP Sciences, 2019)Context. The 51 Eridani system harbors a complex architecture with its primary star forming a hierarchical system with the binary GJ 3305AB at a projected separation of 2000 au, a giant planet orbiting the primary star at ...
-
(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 ...
-
(Elsevier B.V., 2019)A large fossil leaf assemblage (>3700 specimens)is reported from the Oligocene Río Leona Formation in the Sierra Baguales of Chilean Patagonia. The association comprises 29 species but is dominated by Nothofagus genera, ...
-
(Blackwell Munksgaard, 2019)Background and Objective: Over the past few years, the importance of interleukin-22 (IL-22) and T-helper (Th)22 lymphocytes in the pathogenesis of periodontitis has become apparent; however, there are still aspects that ...
-
(Techno Press, 2019)Copyright © 2019 Techno-Press, Ltd.In this paper a novel and efficient computational framework to estimate the stress range versus number of cycles curves experienced by a cable due to external excitations (e.g., seismic ...

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 ...
