mals appears to experience at prefent from the Public in general, but more particularly frommedical practitioners, I am induced to requeft the infertion of the following cafe in the next volume of Medical Fafts and Obfervations. Though it cannot be confidered as containing any material practical improvement, yet its communication may be ufeful, inafmuch as it may excite a degree of more general...

Using a simple theoretical model, we calculate three-dimensional profiles of photoresist exposed by arbitrarily shaped localized fields of high-transmission metal nano-apertures. We apply the finite difference time domain (FDTD) method to obtain the localized field distributions, which are generated by excitation of localized surface plasmon polaritons underneath a C-shaped or a bow-tie-shaped ...

We study in detail the excitation of gap solitons in finite-sized two-dimensional photonic crystals under various kinds of source configuration, including two external beams along different incident directions and a point source at different locations inside the sample. We find different types of gap solitons, such as soliton trains along different symmetry axes of the photonic crystal and soli...

Planning for International Polar Year (IPY) 2007-2008 is well underway. IPY 2007-2008 will be an intense, internationally coordinated campaign of polar observations, research and analysis that will further our understanding of physical and social processes in Polar Regions, examine their globally-connected role in the climate system, and establish research infrastructure for the future. It will...

A mechanism of excitation of the large-scale inertial waves in a rotating inhomogeneous turbulence due to an excitation of a large-scale instability is found. This instability is caused by a combined effect of the inhomogeneity of the turbulence and the uniform mean rotation. The source of the large-scale instability is the energy of the small-scale turbulence. We determined the range of parame...

We propose an alternating optimization framework for the joint design of excitation k-space trajectory and RF pulses for small-tip-angle parallel excitation. Using Bloch simulations, we show that compared with conventional designs with predetermined trajectories, joint designs can often excite target patterns with improved accuracy and reduced total integrated pulse power, particularly at high ...

The vertical excitation energy for the lowest valence pi-->pi(*) transition of cyclopentadiene is investigated. Using a combination of high-level theoretical methods and spectroscopic simulations, the vertical separation at the ground state geometry is estimated to be 5.43+/-0.05 eV. This value is intermediate between those calculated with coupled-cluster and multireference perturbation theory ...

We present an efficient method for producing N particle entangled states using Rydberg blockade interactions. Optical excitation of Rydberg states that interact weakly, yet have a strong coupling to a second control state is used to achieve state dependent qubit rotations in small ensembles. On the basis of quantitative calculations, we predict that an entangled quantum superposition state of e...

We expound on the nature of collapse of one class of tall buildings (steel moment frame buildings) under earthquake excitation. Using a parametric analysis of a couple of index buildings subjected to idealized ground motion histories, we establish the ground motion features that cause collapse in these structures. Systematically mapping damage localization patterns, we track the evolution of th...
