Mechanical Strength of Humidified Glass Beads
(AIP Publishing, 2009)
In this work we measure the mechanical strength of a bed of glass beads that has been previously subjected to a controlled flow of humid air by using a fluidized bed setup. The material is first initialized in a reproducible ...

Lacunary non-continuable boundary-regular holomorphic functions with universal properties
(National Academy of Sciences of the Republic of Armenia, 2006)
A holomorphic function in a Jordan domain G in the complex plane is constructed with all its derivatives extending continuously up to the boundary G that happens to be a natural boundary of In addition the action of a ...

Generalizing Programs via Subsumption
(Springer, 2003)
In this paper we present a class of operators for Machine Learning based on Logic Programming which represents a characterization of the subsumption relation in the following sense: The clause C 1 subsumes the clause C 2 ...

Arsenic sensing and resistance system in the cyanobacterium Synechocystis sp. Strain PCC 6803
(American Society for Microbiology, 2003-09)
Arsenic is one of the most important global environmental pollutants. Here we show that the cyanobacterium Synechocystis sp. strain PCC 6803 contains an arsenic and antimony resistance operon consisting of three genes: ...

Optimality conditions for nonconvex multistate control problems in the coefficients
(Society for Industrial and Applied Mathematics, 2004)
The purpose of this paper is to attain some optimality conditions for the identification of a diffusion matrix (material) under several restrictions. Assuming that the set of such diffusion matrices is closed for the ...

A Modeling Approach Based on P Systems with Bounded Parallelism
(Springer, 2006)
This paper presents a general framework for modelling with membrane systems that is based on a computational paradigm where rules have associated a finite set of attributes and a corresponding function. Attributes and ...

Magnetofluidization of fine magnetite particles
(American Institute of Physics, 2009)
In this study we investigate the behaviour of a fluidized bed of fine magnetite particles as affected by a crossflow uniform magnetic field. Due to the small particle size (35 microns), the fluidized system displays a ...

Nuclear transparencies in relativistic A(e, e′ p) models
(Elsevier, 2004)
Relativistic and unfactorized calculations for the nuclear transparency extracted from exclusive A(e,e′p) reactions for 0.3≤Q2≤10 (GeV/c)2 are presented for the target nuclei C, Si, Fe and Pb. For Q2≥0.6 (GeV/c)2, the ...
