A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1

On the almost intersections of transient Brownian motions
No full textLet {B^d_1 (t )} and {B^d_2 (t )} be independent Brownian motions in R^d starting from 0 and nx
respectively, and let w^d_i (a, b) = {x ∈ R^d : B^d_i (t ) = x for some t ∈ (a, b)}, i = 1, 2. Asymptotic
expressions as n → ∞ for the probability of dist(w^d_1
(n^2 t_1, n^2 t_2), w^d_2 (0, n^2 t_3)) = 4,
respectively for the probability of dist (w^4_1
(n^2 t_1, n^2 t_2),w^4_2 (0, n^2 t_3)) >= 1 are obtained. As an application,
an improvement of a result due to M. Aizenman concerning the intersections of Wiener
sausages in R^4 is presented
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.

Properties of locally linearly independent refinable function vectors
No full textThe paper considers properties of compactly supported, locally linearly independent refinable function vectors Φ=(φ1,…,φr)T, . In the first part of the paper, we show that the interval endpoints of the global support of φν, ν=1,…,r, are special rational numbers. Moreover, in contrast with the scalar case r=1, we show that components φν of a locally linearly independent refinable function vector Φ can have holes. In the second part of the paper we investigate the problem whether any shift-invariant space generated by a refinable function vector Φ possesses a basis which is linearly independent over (0,1). We show that this is not the case. Hence the result of Jia, that each finitely generated shift-invariant space possesses a globally linearly independent basis, is in a certain sense the strongest result which can be obtained

Loosely Coupling Java Algorithms and XML Parsers: a Performance-Oriented Study
No full textL’articolo studia il problema dell’efficienza di caricamento in memoria di grossi documenti XML. Studia le tecniche base di parsine e di memorizzazione in memoria centrale e ne mette in luce i problemi di efficienza e flessibilità.
Partendo da questo studio vengono proposte alcune tecniche di interfacciamento con i parser XML di tipo lasco, che hanno l’obiettivo di lasciare inalterati (o quasi) i programmi/algoritmi preesistenti.
Un accurato studio delle prestazioni di queste tecniche di accoppiamento vien presentato
Advancing knowledge of electrochemically generated lithium microstructure and performance decay of lithium ion battery by synchrotron X-ray tomography
No full textAn intrinsic knowledge gap between current understandings obtained experimentally and the underlying working or degradation mechanisms of rechargeable lithium batteries still remains, giving direct rise to application challenges, e.g., safety issues, predicaments in identifying performance-aging factors and dilemmas in guiding further research directions. Against this background, non-destructive and three-dimensional (synchrotron) X-ray tomography that guarantees a direct visual access to inner electrodes has been employed herein to: in-situ record the evolution of internal short circuits; characterize the behaviors of widely employed separators; investigate the morphological evolution of Li electrodes under different cycling conditions; and study the degradation mechanisms of Li/carbon cells. By incorporating the currently presented results with the previously published studies on those topics, a complete picture of the degradation mechanism of rechargeable lithium batteries has been painted. This advancement of mechanistic understanding supplies the missing pieces of information to bridge fundamental R&D research activities and practical applications
