The light distribution in the inner few kiloparsecs of the Milky Way is recovered non-parametrically from a dust-corrected near-infrared COBE/DIRBE surface brightness map of the inner Galaxy. The best ts to the photometry are obtained when the Sun is assumed to lie 14 4 pc below the plane. The recovered density distributions clearly show an elongated three-dimensional bulge set in a highly non-...
We present a new, fast approach for updating oriented bounding box hierarchies for articulated humanoid models, using a bottom up approach. The algorithm approximates existing techniques by assuming a major body axis. Existence of a major axis allows merging of bounding boxes in a hierarchy approximately but with sufficient accuracy. For scenarios with close proximity a speedup by a factor 2 on...
The renin-angiotensin system (RAS) is a major regulator of renal fibrosis. Besides the classical renin/Angiotensin-converting enzyme (ACE)/angiotensin II (Ang II)/AT1 and AT2 axis, multiple new axes have been recently described. The new members have added new dimensions to RAS, including the ACE2/Ang(1-7)/Mas receptor axis, the prorenin/(pro)renin receptor(PRR)/intracelluar pathway axis, and th...
The Yarkovsky effect is a weak non gravitational force that can modify the semi-major axis of asteroid. It has an important effect on the long term evolution of Near Earth Asteroids. The aim of this paper is to detect secular drift in the semi-major axis of some asteroids. The datamining can help to detect such a drift by extending the orbital arc. Finally the Yarkovsky effect is also considere...
We present a phylogenetic analysis with divergence time estimates, and an ecomorphological assessment of the role of the benthic-to-pelagic axis of diversification in the history of haemulid fishes. Phylogenetic analyses were performed on 97 grunt species based on sequence data collected from seven loci. Divergence time estimation indicates that Haemulidae originated during the mid Eocene (54.7...
Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis is a hallmark of major depressive disorder. A number of studies have shown that this dysregulation is correlated with impaired forebrain glucocorticoid receptor (GR) function. To determine whether a primary, acquired deficit in forebrain GR signaling is an etiologic factor in the pathogenesis of depression, we generated a line of mi...
Cognitive disorders are one of the major public health issues in older population worldwide. Problems in forming and storing new memories, short-term memory impairment, and other cognitive problems are common symptoms of cognitive disorders that have no definite treatment yet. Recent studies have shown an association between gut microbiota and cognitive impairments described as microbiota-gut-...
ABSTRACT We investigate whether the dust content of circum-galactic medium (CGM) depends on location quasar sightline with respect to galaxy major-axis using 13 galaxy-Mg ii absorber pairs (9–81 kpc distance) from MusE GAs FLOw and Wind (MEGAFLOW) survey at 0.4 < z 1.4. The CGM is obtained [Zn/Fe] ultraviolet visual echelle spectrograph data. When a direct measurement unavailable, we est...
We describe the phase space structures related to semi-major axis of Molniya-like satellites subject tesseral and lunisolar resonances. In particular, questions answered in this contribution are: (1) we study indirect interplay critical inclination resonance on semi-geosynchronous using a hierarchy more realistic dynamical systems, thus discussing dynamics beyond integrable approximation. By in...
