On the controllability of the 2-D Vlasov-Stokes system

In this paper we prove an exact controllability result for the Vlasov-Stokes system in the two-dimensional torus with small data by means of an internal control. We show that one can steer, in arbitrarily small time, any initial datum of class C 1 satisfying a smallness condition in certain weighted spaces to any final state satisfying the same conditions. The proof of the main result is achieved thanks to the return method and a Leray-Schauder fixed-point argument

Anatomy of corpus callosum in prenatally malnourished rats

Indexación: Web of Science; ScieloThe effect of prenatal malnutrition on the anatomy of the corpus callosum was assessed in adult rats (45-52 days old). In the prenatally malnourished animals we observed a significant reduction of the corpus callosum total area, partial areas, and perimeter, as compared with normal animals. In addition, the splenium of corpus callosum (posterior fifth) showed a significant decrease of fiber diameters in the myelinated fibers without changing density. There was also a significant decrease in diameter and a significant increase in density of unmyelinated fibers. Measurements of perimeter's fractal dimensions from sagittal sections of the brain and corpus callosum did not show significant differences between malnourished and control animals. These findings indicate that cortico-cortical connections are vulnerable to the prenatal malnutrition, and suggest this may affect interhemispheric conduction velocity, particulary in visual connections (splenium).http://ref.scielo.org/nph4s

Time Left for Intervention in the Suicidal Process in Borderline Personality Disorder

The objective of this study was to measure the duration of the suicidal process among patients diagnosed with Borderline Personality Disorder (BPD). The sample included 110 female patients who met DSM-IV-TR criteria for BPD and were consecutively admitted after suicide-related behavior. A total of 63 patients (58%) reported that their suicidal process lasted 10 minutes or less. After being adjusted, the β coefficient of impulsivity scales in women with a suicidal process ≤10 minutes was lower compared to those observed in women with >10 min (β = −0.03, 95% CI = −0.06 = −0.01, p < 0.01). Suicidal patients with BPD can be divided into two groups; patients who report a suicidal process less than 10 minutes show a higher degree of impulsivity.Fil: Daray, Federico Manuel.

The universal zeta function for curve singularities and its relation with global zeta functions

The purpose of this note is to give a brief overview on zeta functions of curve singularities and to provide some evidences on how these and global zeta functions associated to singular algebraic curves over perfect fields relate to each other.Comment: Survey on the "universal zeta function" defined for curve singularities by W. Z\'u\~niga and the author in their paper "Motivic zeta functions for curve singularities" [Nagoya Math. J. 198 (2010), 47-75]; a poster of it was presented in the "Workshop on Positivity and Valuations" held at the Centre de Recerca Matem\`atica, Barcelona, in 2016 February 22nd-26t

Determinants of mental and physical health-related quality of life among patients hospitalized for suicidal behavior

The current study was interested in exploring the clinical factors related to mental and physical health-related quality of life among patients hospitalized for suicidal behavior. A multicenter cross-sectional study was designed to compare data obtained form 246 patients hospitalized for suicide behavior. Results suggest that mental health-related quality of life was negatively associated with hopelessness while physical health-related quality of life was negatively associated with age, medical disease and the number of previous suicide attempts and positively associated with employment. Findings are discussed in the context of theoretical evidence and clinical implications.Fil: Grendas, Leandro Nicolás. Consejo Nacional de Investigaciones Científicas y Técnicas; Argentina.

Depositional processes and stratigraphic evolution of the Campanian deltaic system of La Anita Formation, Austral-Magallanes Basin, Patagonia, Argentina

Coastal depositional systems are commonly classified in terms of the relative interaction of wave, tide and fluvial processes. The La Anita Formation represents the opportunity to study and better understand coastal sedimentary systems. It is a poorly studied prograding siliciclastic deltaic-coastal wedge accumulated in the Campanian during the foreland stage of the Austral-Magallanes Basin. A detailed depositional process-based facies analysis have allowed the definition of 13 sedimentary facies and 9 facies associations for the La Anita Formation, ranging from prodelta to interdistributary delta-channel deposits. According to the spatial distribution of these facies associations, the La Anita Formation was divided into two informal units bounded by a regional erosion surface. The lower unit shows abundant hummocky cross-bedded and bioturbated sandstones, coarseningupward trends and mainly aggradational to progradational vertical stacking pattern, and it was interpreted as a wave-dominated fluvial-influenced delta. The upper unit is characterized by unidirectional dune cross-bedding, coarseningupward trend and a progradational vertical stacking pattern, and was interpreted as a fluvio-dominated delta with no evidence of tide or wave influence. These two units represent two genetically unrelated depositional sequences bounded by a regional erosion surface, which is interpreted as a sequence boundary triggered by a relative sea-level fall. The lower unit is part of a progradational highstand systems tract which involves the underlying deep-marine Alta Vista Formation. The upper unit deposits reflect a complete relative sea-level cycle which includes an undifferentiated lowstand and transgressive systems tracts and, toward the top, highstand systems tract.Fil: Moyano Paz, Damián.
