In North African countries, cutaneous leishmaniasis transmission has been increasing since the 1980s, with a significant increase in the incidence of cases and a spread of the geographical distribution. The disease currently represents a major public health problem with a productivity gap and an impediment for development, which results in dramatic socioeconomic and psycho-sanitary impacts. The...

This paper describes the second participation of the SINAI research group in the VideoCLEF track. This year we only participated in the subject classification task. A training collection was generated using the data provided by the VideoCLEF organization. Over this data, a supervised learning approach to classify the test videos was conducted. We have used Support Vector Machines (SVM) as class...

This paper describes SINAI team participation in the ImageCLEF campaign. The SINAI research group participated in both the ad hoc task and the medical task. The experiments accomplished in both tasks result from very different approaches. For the adhoc task the main IR system used is the same as that of the 2005 ImageCLEF adhoc task. The improvement of the adhoc system is a new Machine Translat...

We consider the system of N (≥ 2) elastically colliding hard balls of masses m1, . . . , mN and radius r on the flat unit torus T , ν ≥ 2. We prove the so called Boltzmann-Sinai Ergodic Hypothesis, i. e. the full hyperbolicity and ergodicity of such systems for every selection (m1, . . . , mN ; r) of the external geometric parameters, provided that almost every singular orbit is geometrically h...

This paper presents the fourth participation of the SINAI group, University of Jaén, in the Photo Retrieval task at Image CLEF 2009. Our system uses only the text of the queries, and a clustering system (based on kmeans) that combines different approaches based on a different use of the cluster data of the queries. The official results shown that the combination between the title of each query ...

Short summary Bernard Zinman, Programme Committee Chair of the International Diabetes Federation (IDF) World Diabetes Congress 2015, talks about the scientific programme highlights, the experience of attending the Congress and his involvement in diabetes care and research. Bernard Zinman is Director of the Leadership Sinai Centre for Diabetes and holds the Sam and Judy Pencer Family Chair in Di...

The Arabian Peninsula is a key region for understanding hominin dispersals and the effect of climate change on prehistoric demography, although little information on these topics is presently available owing to the poor preservation of archaeological sites in this desert environment. Here, we describe the discovery of three stratified and buried archaeological sites in the Nefud Desert, which i...

The dramatic increase in space-borne sensors over the past two decades is presenting unique opportunities for new and enhanced applications in various scientific disciplines. Using these data sets, hydrogeologists can now address and understand the partitioning of water systems on regional and global scales, yet such applications present mounting challenges in data retrieval, assimilation, and ...

We discuss the impact of recent developments in the theory of chaotic dynamical systems, particularly the results of Sinai and Ruelle, on microwave experiments designed to study quantum chaos. The properties of closed Sinai billiard microwave cavities are discussed in terms of universal predictions from random matrix theory, as well as periodic orbit contributions which manifest as ‘scars’ in e...
