Elliptic curves of large rank and small conductor

For r=6,7,...,11 we find an elliptic curve E/Q of rank at least r and the smallest conductor known, improving on the previous records by factors ranging from 1.0136 (for r=6) to over 100 (for r=10 and r=11). We describe our search methods, and tabulate, for each r=5,6,...,11, the five curves of lowest conductor, and (except for r=11) also the five of lowest absolute discriminant, that we found.Comment: 16 pages, including tables and one .eps figure; to appear in the Proceedings of ANTS-6 (June 2004, Burlington, VT).

The relationship between depression and violence risk predictors on Elderly

The purpose of this study was to understand the correlation between the elderly with depressive symptomatology and the predictors of the risk of violence against them. The method used was a quantitative approach using the Statistical Package program for Social Sciences. There was a participation of 237 elderly people aged 65-96 years, of the project “Aging in Safety in Alentejo - Understanding to Act”, at the University of Évora. The Geriatric Depression Scale and the Predictors of Risk of Violence (an adaptation of the Elder Abuse and Neglect-Risk Assessment Tool and Vulnerability to Abuse Screening Scale) were applied. About the results, 50 elderly (21.1%) had mild depressive symptomatology, and 14 (5.9%) had severe depressive symptomatology. Of the 64 elderly individuals who presented depressive symptomatology 55 were female. In the relationship between the severity of depressive symptomatology and predictors of risk of violence, significant results were found in three dimensions: current supports and relationships, family context and cognitive / emotional difficulties. The main conclusion of the study is that factors like no social support networks, complex family context and cognitive and emotional changes, contribute to greater physical and mental vulnerability of the elderly, resulting in cases of anxiety and stress, which present a depressive symptomatology and the risk of violence

Open source technologies involved in constructing a web-based football information system

The current information systems and match analysis software associated to professional football output a huge amount of statistics. Many football professionals are particularly interested in real time information about the tactical plan occurring during the match, and the relations between that information and what was prepared in the training sessions. It is fundamental to have on the bench, and on-the-fly, the most relevant information each time they have to take a decision. In this paper, we present a set of open source technologies involved in building a multi-platform web based integrated football information system, supported in three main modules: user interfaces, databases, and the tactical plan detection and classification. We show that the selected technologies are suitable for those modules, allowing field occurrences to trigger meaningful information

Testing Hardy nonlocality proof with genuine energy-time entanglement

We show two experimental realizations of Hardy ladder test of quantum nonlocality using energy-time correlated photons, following the scheme proposed by A. Cabello \emph{et al.} [Phys. Rev. Lett. \textbf{102}, 040401 (2009)]. Unlike, previous energy-time Bell experiments, these tests require precise tailored nonmaximally entangled states. One of them is equivalent to the two-setting two-outcome Bell test requiring a minimum detection efficiency. The reported experiments are still affected by the locality and detection loopholes, but are free of the post-selection loophole of previous energy-time and time-bin Bell tests.Comment: 5 pages, revtex4, 6 figure
