For over a century, hydrogeologists have estimated hydraulic conductivity (K) from grain-size distribution curves. The benefits of the practice are simplicity, cost, and a means of identifying spatial variations in K. Many techniques have been developed over the years, but all suffer from similar shortcomings: no accounting of heterogeneity within samples (i.e., aquifer structure is lost), loss...

Action-Graph Games (AGGs) (Bhat & Leyton-Brown 2004) are a fully expressive game representation which can compactly express strict and context-specific independence and anonymity structure in players’ utility functions. We present an efficient algorithm for computing expected payoffs under mixed strategy profiles. This algorithm runs in time polynomial in the size of the AGG representation (whi...

The dynamic nanomechanical characteristics of Cu films with different grain boundaries under nanoindentation and scratch conditions were studied by molecular dynamics (MD) simulations. The type of grain boundary is the main factor in the control of the substrate atoms with respect to the size of dislocations since the existence of the grain boundary itself restricts the movement associated with...

The grain boundary embrittlement (GBE) of metal copper caused by bismuth segregation has been extensively studied both experimentally and theoretically(l-10). By using the orientation-controlled bicrystals, the strong dependence of Bi segregation and GBE upon grain boundary(GB) structures has been revealed (3-7). A systematic study of the dependence of the GBE upon the GB structures, for [ 1 lo...

A coarse-grain parallel program typically has one thread (task) per processor, whereas a ne-grain program has one thread for each independent unit of work. Although there are several advantages to ne-grain parallelism, conventional wisdom is that coarse-grain parallelism is more eecient. This paper illustrates the advantages of ne-grain parallelism and presents an eecient implementation for sha...

Introduction: Ice grain size controls the geodynamic evolution of the ice I shells of large to mid-sized icy satellites. Grain size controls the viscosity of ice [1,2], and thus, the heat flux from the outer ice I shell by controlling the likelihood and efficiency of convection. In addition, the rheology of ice controls the depth to the brittle/ductile transition, which is a key control on endo...

The grain coarsening in dense nanocrystalline gadolinia-doped ceria (CGO) and CeO2 was studied for the grain size regime from 10 to 250 nm. Dense ceria-based thin films were prepared by spray pyrolysis and pulsed laser deposition on sapphire substrates. The small grain-sized CGO and CeO2 microstructures were surprisingly stable and showed self-limited grain growth and relaxation of the microstr...

Grain v1 is one of the 7 final candidates of ECRYPT eStream project, which involves in the 80-bit secret key. Grain-128 is a variant version with 128-bit secret key, and Grain v0 is the original version in the first evaluation phase. Firstly, we describe a distinguishing attack against the Grain family with weak Key-IVs. Utilizing the second Walsh spectra of the nonlinear functions, we show tha...

This study aimed to compare the color stability and surface roughness of three-dimensional (3D) printing resin according polishing methods. 3D-printed specimens were fabricated at TC-80DP (Graphy, Seoul, Korea) with a stereolithography 3D printer, divided into three groups, each which was not polished, polished using Enhance®, Sof-Lex<sup>TM</sup> disc. The CIE L*a*b* value group me...
