Our examination of the interplay ultrafast charge dynamics and electron-phonon interaction in bilayer MoS2 provides a microscopic basis for understanding features (two peaks) emission spectrum. We demonstrate that while initial accumulation excited occurs at near Q point two-dimensional Brillioun zone, takes place predominantly through two pathways: direct recombination K indirect phonon-assist...

introduction the fanuj titaniferous placer deposits are located 35 km northwest of the fanuj, sistan and baluchestan province (1) . the studied area comprises a (2) small part of the late cretaceous fanuj-maskutan (rameshk) ophiolite complex (arshadi and mahdavi, 1987). reconnaissance and comprehensive exploration programs in the fanuj district (east of the 1:100000 fanuj quadrangle map,yazdi, ...

The Israeli population of Eurasian otter (Lutra lutra) marks the Palearctic southern boundary of the species' distribution in the Levant. During the 20th century, the otter population in Israel experienced a dramatic decline due to anthropogenic habitat alterations. Currently, the otter population in Israel is estimated at about 100 individuals and defined as "Critically Endangered". The aim of...

Abstract The surface evolution model based on geometric partial differential equation is used to numerically study the kinetics of dewetting and dynamic morphologies for the localized pinhole defect in the surface of the ultrathin solid film with the strongly anisotropic surface energy. Depending on parameters such as the initial depth and width of the pinole, the strength of the attractive sub...

Progress is reported on a 25 MeV injector racetrack microtron for a 10 wm radiation free electron laser (TEUFEL project). The accelerator exhibits transverse focusing in 180° inhomogeneous two-sector dipole magnets which are slightly rotated with respect to each other in the bending plane . This provides closed orbits, isochronism and a large transverse acceptance. Details on this unconventiona...

The testing effect is the finding that taking an initial test enhances the likelihood of later recall. The present report examines the extent to which this benefit of testing comes with a cost: an enhanced likelihood of erroneously recalling incorrect information. Subjects were given short lists of semantic associates (e.g., hill, valley, climb); each list converged upon a related nonpresented ...
