BlotBase: a northern blot database.

2008

With the availability of high-throughput gene expression analysis, multiple public expression databases emerged, mostly based on microarray expression data. Although these databases are of significant biomedical value, they do hold significant drawbacks, especially concerning the reliability of single gene expression profiles obtained by microarray data. Simultaneously, reliable data on an individual gene's expression are often published as single northern blots in individual publications. These data were not yet available for high-throughput screening. To reduce the gap between high-throughput expression data and individual highly reliable expression data, we designed a novel database "Blo…

Rejection odds and rejection ratios: A proposal for statistical practice in testing hypotheses

2016

Much of science is (rightly or wrongly) driven by hypothesis testing. Even in situations where the hypothesis testing paradigm is correct, the common practice of basing inferences solely on p-values has been under intense criticism for over 50 years. We propose, as an alternative, the use of the odds of a correct rejection of the null hypothesis to incorrect rejection. Both pre-experimental versions (involving the power and Type I error) and post-experimental versions (depending on the actual data) are considered. Implementations are provided that range from depending only on the p-value to consideration of full Bayesian analysis. A surprise is that all implementations -- even the full Baye…

Association between family environment and the bullying phenomenon among school-age children: A systematic review

2019

There is a lack of evidence about the possible role of the family environment in the occurrence of the bullying phenomenon among school-age children. We carried out a systematic review of the literature to investigate the positive and negative family determinants associated with the bullying phenomenon. Potential classes of determinants-e.g. interparental conflict and/or parenting behaviours-were studied by searching peer-reviewed literature published between the January 2008 and December 2018 on PubMed/MEDLINE, SCOPUS and ISI Web of Science. At the end of the eligibility process, only 3 studies met all the inclusion criteria, and were then included in the narrative synthesis. Mother destru…

Integration of a Dirac comb and the Bernoulli polynomials

2016

Abstract For any positive integer n , we consider the ordinary differential equations of the form y ( n ) = 1 − Ш + F where Ш denotes the Dirac comb distribution and F is a piecewise- C ∞ periodic function with null average integral. We prove the existence and uniqueness of periodic solutions of maximal regularity. Above all, these solutions are given by means of finite explicit formulae involving a minimal number of Bernoulli polynomials. We generalize this approach to a larger class of differential equations for which the computation of periodic solutions is also sharp, finite and effective.

Historical Part—Calculus of Variations

2018

The calculus of variations is an old mathematical discipline and historically finds its origins in the introduction of the brachistochrone problem at the end of the 17th century by Johann Bernoulli to challenge his contemporaries to solve it. Here, we briefly introduce the reader to the main results.

Trial Methods for Nonlinear Bernoulli Problem

1997

In this article we consider a free boundary problem which is related to formation of waves on a fluid surface (for example the ship waves). We study the possibility to construct ‘trial’ methods where one solves a sequence of standard flow problems formulated in different geometries that converge to the final free boundary. Furthermore, we use the shape optimization techniques to analyse the convergence of the fixed point iteration near a fixed point. For stream function case we conclude that the fast convergence can be obtained by using non-standard boundary conditions and we present numerical results to confirm the analysis.

Cultura i Llibertat. La biblioteca de 'Misiones Pedagógicas' de Cullera

2003

La conservació a l'Arxiu Municipal de Cullera de documentació relacionada amb la Biblioteca enviada pel Patronato de Misiones Pedagógicas, ens permet apropar-nos a la realitat de l'obra de divulgació cultural realitzada per aquesta institució dins del marc concret de Cullera. El fet que estigueren implicades tres persones com Maria Moliner, Maria Camilleri i Lamberto Oliver fa que puguem acostar-nos a les seues trajectòries personals i professionals.
