Time series of regional 2° × 2° Gravity Recovery and Climate Experiment (GRACE) solutions of surface water mass change have been computed over Africa from 2003 to 2012 with a 10-day resolution by using a new regional approach. These regional maps are used to describe and quantify water mass change. The contribution of African hydrology to actual sea level rise is negative and small in magnitude...

This study investigated the effect of ego–depletion on the automatic and controlled components of stereotype–based responses. Participants engaged in a depleting task for either a short or a long period of time. They then performed a weapon identification task, which served as a measure of race stereotyping. Analyses guided by the L.L. Jacoby’s (1991) process dissociation procedure indicated th...

We present a model of quasi-phase-matched continuous-wave optical parametric oscillators that accounts for self-induced heating of the photorefractive crystal and modal interaction through pump depletion. The model allows the temperature and therefore the refractive index of the nonlinear medium to vary in the radial and longitudinal dimensions as a result of local absorption of the optical pow...

Spin current generation in silicon and other semiconductors by purely electrical means is paramount for building spintronic devices. Recently, a robust spin injection into a semiconductor from a ferromagnetic metal contact has been performed at room temperature [1], but the spin accumulation signal obtained with the three-terminal measurement setup is reported to be higher than the theoretical ...

We have performed simulations on electron spin transport in an n-doped silicon bar with spin-dependent conductivity with or without the presence of an external electric field. We further consider three cases like charge neutrality, charge accumulation, and charge depletion at one boundary and found substantial differences in the spin transport behavior. The criteria determining the maximum spin...

Effects of medium polarization are studied for 1S0 pairing in neutron and nuclear matter. The screening potential is calculated in the RPA limit, suitably renormalized to cure the low density mechanical instability of nuclear matter. The selfenergy corrections are consistently included resulting in a strong depletion of the Fermi surface. All medium effects are calculated based on the Brueckner...

A small, off-axis mesh-anode electrode at one plasma-column end is used to create a paraxial channel of electron current and depleted density in the large plasma device upgrade at UCLA. We show that the on-axis, larger, surroundingplasma column rotates about its cylindrical axis because a radial electric field is imposed by a multiple-segmented-disc termination electrode on the same end as the ...

In this paper, we present a transient modeling of electromigration (EM) in TSV and TSV-to-wire interfaces in the power delivery network (PDN) of 3D ICs. In particular, we model atomic depletion and accumulation, effective resistance degradation, and full chip-scale PDN lifetime degradation due to EM. Our major focuses are on: (1) timedependent multi-physics EM modeling approach to model TSVs an...

Understanding the formation and spatial-temporal distribution of soil salt crusts (SSCs) is important for the sustainable management of the artificial shelterbelt and high-salinity groundwater utility in the Taklimakan Desert in Northwest China. The SSCs in this area were sampled, and their thickness and electrical conductivity (EC) were analyzed to examine the formation mechanism and the spati...

Photorefractive (PR) holograms can be fixed with various degrees of success.1-4 These usually involve the replacement of the original electronic charge by a relatively immobile ionic charge. When such holograms are reconstructed, by illuminating with the readout wave, a new dynamic electronic hologram is generated by the spatial interference of the readout and the diffracted waves. The superpos...
