Chirally stacked N-layer graphene systems with N≥2 exhibit a variety of distinct broken symmetry states in which charge density contributions from different spins and valleys are spontaneously transferred between layers. We explain how these states are distinguished by their charge, spin, and valley Hall conductivities, by their orbital magnetizations, and by their edge state properties. We arg...

rijab valley, located in 180 km west of kermanshah, is considered to be one of the tourists centers of kermanshah because of having various landscapes and monuments. however, the results of one of the field studies of 157 tourist subjects show that the majority of the tourists do not know much about all the attractions of the valley. in a way that about 31.2% of the tourists were not aware of t...

Protected areas are major tourism assets for a nation, particularly for developing countries providing sustainable benefit to the local community while funding for the maintenance and rehabilitation of the protected areas themselves. Valley of flowers national park is naturally meant for the conservation and study of western Himalayan flora. It became National park in 1982 and after that livest...

Kuhbanan fault system, as one of the intracontinental faults of central Iran, is recognized by considerable seismogenic activities and modern morphotectonics evidences with a strike-slip (reverse component) motion. According to the geometric and kinematics data, Kuhbanan fault has been divided into 5 segments (S26, S27, S28, S29, S30) in Bahabad region. Measured geomorphic indices of ratio of v...

Are the inventor networks of Silicon Valley more densely connected than those of the Boston Route 128 corridor? The evidence remains mostly historical and controversial to date. We develop an analysis of all the patented inventors in both regions since 1975 and find that the networks of Silicon Valley are simultaneously more connected and less robust than those of Boston. Of greatest interest, ...

Electron states are studied for quantum dots in a strained Si quantum well, taking into account both valley and orbital physics. Realistic geometries are considered, including circular and elliptical dot shapes, parallel and perpendicular magnetic fields, and most importantly for valley coupling the small local tilt of the quantum-well interface away from the crystallographic axes. In absence o...

The potential for basin amplification of ground motion from significant seismic sources 100-200 km (62-124 mi.) from the Las Vegas Valley (such as the Death Valley Fault System) and Quaternary faults in the valley could provide sufficient energy to cause liquefaction. Key criteria of liquefiable soils coupled with a shallow groundwater table (less than 15 m (50 ft)) are met at several sites in ...

The Kordkanlo Basin, one of the Atrak sub-basins, located in the northeastern of the Ghoochan city, the Khorasan Razavi Province; is situated in Kopet Dagh geologic zone. The overall objective of this study is to evaluate the morphotectonic effects on the drainage network of the basin, using morphometric indicators. In this research, morphometric quantitative indicators of hypsometric integral ...

The hexanic extract composition of two populations of Lippia graveolens growing in an arid zone in the Tehuacán-Cuicatlán Valley (Zapotitlán Salinas, Puebla), Central Mexico, in different seasons of the year, and in contrasting conditions of ecological disturbance has been studied by GC and GC-MS. Regarding to the composition of these extracts, qualitative differences among the two populations ...
