The Manning friction coefficient as a one-dimensional (1D) openchannel flow parameter is determined from a series of two-dimensional (2D) simulations of the flow on steep slopes using a computational hydraulic solver derived from a minimal intervention strategy (MIS2D). Computations are also conducted for the oblique dam-break waves to evaluate the performance of MIS2D. The results are compared...

Tea, one of the most commonly consumed beverages in the world, has many health benefits. Tea polyphenols support health by promoting antioxidant enzymes, promoting apoptosis, preventing angiogenesis, and modulating epigenetic change. Considerable basic science and epidemiologic evidence supports the regular consumption of this tasty, inexpensive beverage.

This research used points extracted from high-resolution DEMs (1m) to investigate the impact of resolution, interpolation method and topography on accuracy drainage network extraction. The investigation was conducted by evaluating estimations streams length, number, density, Longitudinal Root Mean Square Error (LRMSE) networks different interpolated using Topo raster, Natural Neighbor (NN), kri...

We present the results of EVN+MERLIN VLBI polarization observations of 8 Broad Absorption Line (BAL) quasars at 1.6 GHz, including 4 LoBALs and 4 HiBALs with either steep or flat spectra on VLA scales. Only one steep-spectrum source, J1122+3124, shows two-sided structure on the scale of 2 kpc. The other four steep-spectrum sources and three flat-spectrum sources display either an unresolved ima...

We present a theory of adaptive optimization for umbrella sampling. With the analytical bias force constant obtained from the constrained thermodynamic length along the reaction coordinate, the windows are distributed to optimize the overlap between neighbors. Combining with the replica exchange method, we propose a method of adaptive window exchange umbrella sampling. The efficiency gain in sa...

BACKGROUND To evaluate the torsional and flattening effect of steep meridian incisions and influence of posterior corneal astigmatism (PCA) on total corneal astigmatism (TCA) after cataract surgery. METHODS One hundred thirty-two eyes underwent cataract surgery with steep meridian 2.2 mm microcoaxial and 2.85 mm conventional clear corneal incisions. Eyes were divided into with-the-rule (WTR) ...
