In this article, we show that a finite dimensional Hilbert space can have an infinite Bessel sequence, but a normalized Bessel sequence in a finite dimensional Hilbert space must be of finite length. A relation between the dimension of a given finite dimensional Hilbert space and the bound of any finite normalized tight frame for the underlying space is obtained. Also some properties of the fra...

Oncolytic viral therapy is under evaluation for toxicity and efficacy in clinical trials relating to several different tumors. We report a significant increase in the angiogenic index of oncolytic virus (OV)-treated glioma-matrigel implants (2.83-fold, P < 0.02). In a rat intracranial glioma model, large tumors from OV-treated animals were significantly more angiogenic than the phosphate-buffer...

To increase public health awareness for prevention of opisthorchiasis caused by eating raw freshwater fish, the distribution and abundance of Opisthorchis viverrini metacercariae (OV MC) was investigated in freshwater fish obtained from 20 provinces in northeastern Thailand between April 2011 and February 2012. A cross-sectional survey was conducted on 12,890 fish consisting of 13 species rando...

In this paper we show that every g-frame for a Hilbert space H can be represented as a linear combination of two g-orthonormal bases if and only if it is a g-Riesz basis. We also show that every g-frame can be written as a sum of two tight g-frames with g-frame bounds one or a sum of a g-orthonormal basis and a g-Riesz basis for H . We further give necessary and sufficient conditions on g-Besse...

Background—The aim of this study was to validate exhaled nitric oxide (eNO) values obtained with an alternative oV line, single breath, low flow balloon sampling method against on line sampling according to ERS and ATS guidelines in children who could perform both methods. Methods—One hundred and twenty seven white children of median age 14.1 years, all pupils of a secondary school, participate...

Much of the literature on victimization looks at effect organized violence (OV) civilian perceptions and behaviour. Yet citizens in countries experience quotidian crime (QC) a daily basis. QC differs from OV, former being more isolated, while latter is collective experience. As such we develop theoretical framework that explores effects both types preferences for public goods. Victims OV may pr...

Résumé. Dans cet article, nous montrons comment les techniques de fouilles de données peuvent résoudre efficacement le problème de la réécriture de requêtes en termes de vues en présence de contraintes de valeurs. A partir d’une formalisation du problème de la réécriture dans le cadre de la logique de description ALN (Ov), nous montrons comment ce problème se rattache à un cadre de découverte d...

We report on an interferometry-based measurement of the phase and group velocities of optical Bessel beams, providing confirmation of their superluminal character in the non-diffractive region. The measurements were performed in free space with a continuous wave laser and femtosecond pulses for phase and group velocities respectively. The Bessel beams were produced using a conical mirror. Einst...

Abstract: We define q-analogues of Fourier-Bessel series, by means of complete qorthogonal systems constructed with the third Jackson q-Bessel function. Sufficient conditions for pointwise convergence of these series are obtained, in terms of a general convergence principle valid for other Fourier series on grids defined over numerable sets. The results are illustrated with specific examples of...
