A robust valley polarization is a key prerequisite for exploiting valley pseudospin to carry information in next-generation electronics and optoelectronics. Although monolayer transition metal dichalcogenides with inherent spin-valley coupling offer a unique platform to develop such valleytronic devices, the anticipated long-lived valley pseudospin has not been observed yet. Here we demonstrate...

Introduction: Terrestrial cold-based glacial analogs [1,2] have recently been applied to the analysis of fan-shaped deposits on the NW flanks of the Tharsis Montes and Olympus Mons, interpreting them to represent extensive tropical mountain glaciers formed by enhanced snow and ice deposition during periods of high obliquity in the Amazonian [3-8]. Additional Earth glacial analogs have been used...

This paper centers on ancient, generally rather scattered and elusive remains of gameplay. Focusing on a discreteassemblage of game-related artefacts from the Bronze Age Indus Valley urban settlement of Mohenjo-daro, it conductsa detailed study of some of the patchy features to see whether more structured elements thereby can be distinguished.The finds are approached situated in a broader, game...

a preliminary palaeomagnetic results from basalt outcrops in northeast lebanon is reported. the remanence carrier of the characteristic magnetisation is magnetite.  both variations of susceptibility and anisotropy directional data show that the measured directions of thermoremanent magnetisation (trm) are representative of the ambient field at the time of cooling of these basalts through their ...

A survey of adult behaviour of Culex (Culex) species was carried out from August 1992 through December 1993 in a human modified (anthropic) environment in the Ribeira Valley, S. Paulo State, Brazil. Culex nigripalpus dominated the catches at several sites and it's tendency to increase in the anthropic environment became quite clear. Nevertheless no high level of synanthropy was demonstrated. So...

Against the background of the uncanny valley hypothesis we investigated how people react towards an android robot in a natural environment dependent on the behavior displayed by the robot (still vs. moving) in a quasiexperimental observational field study. We present data on unscripted interactions between humans and the android robot “Geminoid HI-1” in an Austrian public café and subsequent in...

Rift Valley fever (RVF) is a zoonotic disease endemic in sub-Saharan Africa with periodic outbreaks in human and animal populations. Mosquitoes are the primary disease vectors; however, Rift Valley fever virus (RVFV) can also spread by direct contact with infected tissues. The transmission cycle is complex, involving humans, livestock, and multiple species of mosquitoes. The epidemiology of RVF...

A practice-based method is advanced to understand the emergence and transformation of agricultural practices in the Upper Wahgi valley during the Holocene. Conceptually, practices represent the nexus of human–environment interactions, as well as of structure–agency relationships, while methodologically, they are the visible remains – whether encountered directly through archaeology, or inferred...

The Janneh dam is a 162-meter high Roller Compacted Concrete arch-gravity dam under construction in the Nahr Ibrahim Valley of Lebanon. The impounded reservoir will supply water, irrigate agricultural areas and generate hydropower [1]. The dam will serve the Northern areas of Greater Beirut Mount Lebanon [2]. The project site is located in highseismicity region. The Peak Ground Accelerations ar...
