Recent archaeological field work in Tacna (Peru) has investigated the long-term landscape history of Sama Valley. Located between research hotspots Moquegua and Arica, valley long been overlooked. At same time, it is well positioned to offer new insights into debates about mobility, environment, transforming political economies Late Prehispanic historic periods. This article presents an initial...

Topological photonics has emerged as a promising field in that is able to shape the science and technology of light. As significant degree freedom, valley introduced design construct photonic topological phases, with encouraging recent progress applications ranging from on-chip communications terahertz lasers. Herein, development reviewed, both perspectives fundamental physics practical applica...

In this letter we study the valley degeneracy splitting of the transition-metal dichalcogenide monolayer by first-principles calculations. The local magnetic moments are introduced into the system when the transition-metal atoms are adsorbed on the monolayer surface. The Zeeman effect arising from the local magnetic moment at transition-metal atom sites lifts the valley degeneracy. Anomalous ch...

[1] Glacial occupation of alpine valleys results in a distinct signature in the long-valley profile, including steepening of the profile in the headwaters, flattening at lower elevations, and a step in the profile at the convergence of headwater tributaries. We present analytic results for glacial erosion patterns by making the following assumptions: (1) the initial profile is linear, (2) the w...

Stream habitat assessments are conducted to evaluate biological potential, determine anthropogenic impacts, and guide restoration projects. Utilizing these procedures, managers must first select a representative stream reach, which is typically selected based on several criteria. To develop a consistent and unbiased procedure for choosing sampling locations, the Illinois Department of Natural R...

Melioidosis, caused by the highly recombinogenic bacterium Burkholderia pseudomallei, is a disease with high mortality. Tracing the origin of melioidosis outbreaks and understanding how the bacterium spreads and persists in the environment are essential to protecting public and veterinary health and reducing mortality associated with outbreaks. We used whole-genome sequencing to compare isolate...

More than 1.5 million people live in the Kathmandu valley. The valley is facing an extreme shortage of water supply. At the same time the demand is escalating rapidly. To address this issue of scarcity of water, the government of Nepal has proposed a project of inter-basin transfer of water from Melamchi River located 40 km north-east of the Kathmandu valley. The project will cover two district...

Synergies among technological opportunities, market perspectives, and geographical endowments can be considered as indicators of systemness. Using information theory, we propose a measure of synergy among size-classes, zip-codes, and NACE-codes for 8.5 million American firms. The synergy at the national level is decomposed at the level of states and CoreBased Statistical Areas (CBSA) as regions...

[1] We present evidence that a final epoch of widespread fluvial erosion and deposition in the cratered highlands during the latest Noachian or early to mid-Hesperian was characterized by integration of flow within drainage networks as long as 4000 km and trunk valley incision of 50 to 350 m into earlier Noachian depositional basins. Locally deltaic sediments were deposited where incised valley...
