We present two high-resolution local models for the crustal magnetic field of the Martian south polar region. Models SP130 and SP130M were derived from three-component measurements made by Mars Global Surveyor at nighttime and at low altitude (<200 km). The availability area for these data covers the annulus between latitudes −76∘ and −87∘ and contains a strongly magnetized region (southern par...

The Mediterranean climate prevailing on the coastal belt of the Mediterranean Sea undergoes to change toward the inner part of the Anatolia in accordance with the increase of altitude, mountain range barriers, the tectonic structure of the region, and tectonic-karstic depressions. Continentality also plays a critical role in the micro-climates that prevail across the various eco-regions. This s...

Previous studies of brain glucose metabolism in people indigenous to high-altitude environments uncovered two response patterns: Quechuas native to the high Andes of South America sustained modest hypometabolism in most brain regions interrogated, whereas Sherpas, native to the Himalayas and considered by many biologists to be most effectively high-altitude adapted of all humans, showed brain m...

Selenium (Se) levels in blood (whole blood, erythrocytes and serum) and blood glutathione peroxidase (GSH-Px) activity were investigated in people living at high altitude in Bolivia (4,000 m above sea level). These parameters were compared to those of people living at low altitude (300 m above sea level). The Se levels in whole blood of the high-altitude subjects did not differ significantly fr...

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

High mountain ecosystems are among the most sensitive environments to changes in climatic conditions occurring on global, regional and local scales. The article describes the changing conditions observed over recent years in the high mountain basin of the Claro River, on the west flank of the Colombian Andean Central mountain range. Local ground truth data gathered at 4150 m, regional data avai...

The number of pulsars with detected emission at X-ray and γ-ray energies has been steadily growing, showing that beams of high-energy particles are commonly accelerated in pulsar magnetospheres, even though the location and number of acceleration sites remain unsettled. Acceleration near the magnetic poles, close to the polar cap surface or to higher altitudes in the slot gap along the last ope...

Extreme precipitation events can lead to severe mountain hazards, and they have therefore received widespread attention. The study of extreme be hindered by the insufficient number uneven distribution rain gauge stations, especially in mountainous areas with complex terrain. In this study, daily data three gridded products (Integrated Multi-satellite Retrievals for GPM, IMERG; Multi-Source Weig...
