An attempt was made to compensate for the lack of long hydrological time series and the lack of information on maximum streamflow in the Alzette River basin (Luxembourg) via the regionalization of stormflow coefficients. Streamflow data recorded since 1995 with a very dense streamgauge network allowed the determination of maximum stormflow coefficients in 18 sub-basins of the Alzette. The storm...

Somites are transient structures which represent the most overt segmental feature of the vertebrate embryo. The strict temporal regulation of somitogenesis is of critical developmental importance since many segmental structures adopt a periodicity based on that of the somites. Until recently, the mechanisms underlying the periodicity of somitogenesis were largely unknown. Based on the oscillati...

The diencephalon is the caudal part of the developing forebrain, which corresponds to prosomeres 1 to 3. The mature diencephalon is functionally and anatomically divided into well-defined nuclei. Previous researches have shown that LIM-homeobox genes are important transcription factors during diencephalon regionalization in mice. Here we examined expression patterns of several chick orthologs o...

We study the control of modulational instability and pattern formation in a nonlinear dissipative feedback system with a periodic modulation of the material refractive index. We use a one-dimensional photonic lattice in a single-mirror feedback configuration and identify three mechanisms for pattern control: bandgap suppression of instability modes, periodicity induced pattern modes, and orient...

The leaders of such global powerhouses as GE, Wal-Mart, and Toyota seem to have grasped two crucial truths: First, far from becoming submerged by the rising tide of globalization, geographic and other regional distinctions may in fact be increasing in importance. Second, regionally focused strategies, used in conjunction with local and global initiatives, can significantly boost a company's per...

We present some numerical results obtained from a simple individual-based model that describes clustering of organisms caused by competition. Our aim is to show that, even when a deterministic description developed for continuum models predicts no pattern formation, an individual-based model displays well-defined patterns, as a consequence of fluctuation effects caused by the discrete nature of...

Efforts to develop trauma systems in the United States followed the publication of the landmark article, "Accidental Death and Disability: The Neglected Disease of Modern Society," by the National Academy of Sciences (1966) and have resulted in the implementation of a system of care for the seriously injured in most states and within the US military. In 2007, Hoyt and Coimbra published an artic...

The present work displays an investigation focused on the understanding of sociology institutionalization in Mexico, and if it is possible to be spoken of an academic crisis of sociology, as it is handled nowadays, besides an investigation that takes care of specific values of the sociological knowledge in the reality of each region in Mexico. This approach starts, firstly, in a study of the so...

The telencephalic vesicles form in the mouse embryo by the expansion of precursor regions in the anterior neural tube. Once the vesicles have formed, discrete dorsal and ventral territories can be recognized that later give rise to cortical and subcortical structures, respectively. To investigate the mechanisms that regulate the expansion and regionalization of the telencephalon, we have carrie...
