Thermal equilibrium and statistical thermometers in special relativity
(American Physical Society, 2007)
There is an intense debate in the recent literature about the correct generalization of Maxwell’s velocity distribution in special relativity. The most frequently discussed candidate distributions include the Jüttner ...
Volume fluctuations and compressibility of a vibrated granular gas
(American Physical Society, 2010)
The volume fluctuations in the steady state reached by a vibrated granular gas of hard particles confined by a movable piston on the top are investigated by means of event-driven simulations. Also, a compressibility factor, ...
Alr0397 is an outer membrane transporter for the siderophore schizokinen in Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2008)
Iron uptake in proteobacteria by TonB-dependent outer membrane transporters represents a well-explored subject. In contrast, the same process has been scarcely investigated in cyanobacteria. The heterocyst-forming ...
Computing Homology Groups in Binary 2D Imagery by Tissue-like P Systems
(Romanian Academy, Section for Information Science and Technology, 2010)
We present a new solution for the Homology Groups of Binary 2D Image (HGB2I) Problem by using Membrane Computing techniques. This is a classical problem in Homology Theory which tries to calculate the number of connected ...
A continuation method for weakly Kannan maps
The first continuation method for contractive maps in the setting of a metric space was given by Granas. Later, Frigon extended Granas theorem to the class of weakly contractive maps, and recently Agarwal and O’Regan have ...
Design of a 130-nm CMOS Reconfigurable Cascade ΣΔ Modulator for GSM/UMTS/Bluetooth
(Institute of Electrical and Electronics Engineers, 2007)
This paper reports a 130-nm CMOS programmable cascade ΣΔ modulator for multistandard wireless terminals, covering three standards: GSM, Bluetooth and UMTS. The modulator is reconfigured at both architecture- and ...
Towards Automatic Code Generation for EAI Solutions using DSL Tools
(Asociación de Ingeniería del Software y Tecnologías de Desarrollo de Software (SISTEDES), 2009)
Current companies count on heterogeneous information technology applications to perform their activities. More often than not, they need to be integrated so that the data they manage is kept in sync or to implement ...
A sufficient degree condition for a graph to contain all trees of size k
The Erdös–Sós conjecture says that a graph G on n vertices and number of edges e(G) > n(k − 1)/2 contains all trees of size k. In this paper we prove a sufficient condition for a graph to contain every tree of size k ...
An Analytical Study of the Delay in Bluetooth Networks Using the Personal Area Network Profile
(IEEE Computer Society, 2007)
Bluetooth is the most employed technology to develop Wireless Personal Area Networks. This letter studies the performance of Bluetooth transmissions that make use of the PAN (Personal Area Network) profile. In particular, ...
Dynamics and numerical simulations to predict empirical antibiotic treatment of multi-resistant Pseudomonas aeruginosa infection
This work discloses an epidemiological mathematical model to predict an empirical treatment for dogs infected by Pseudomonas aeruginosa. This dangerous pathogen is one of the leading causes of multi-resistant infections ...
