Effects of nitrogen incorporation into Hf-based high-k gate dielectrics have been extensively studied via first-principles calculations. Particular emphasis is given to the relationship between incorporation of N atoms and oxygen vacancies (Vos). Three important aspects are outlined in this paper. The first one is the intrinsic effect of N atoms in reducing the leakage current mediated by V0 related gap states. The second one is the suppression of electron charge traps at V0 due to the strong repulsive Coulomb potential from N 3- ions located around V0. The third one is the acceleration of the V0 formation around N ions. From these analyses, we infer that the amount of N incorporation should be tuned in the fabrication of reliable gate insulators.

The complexity of parallel PDE-based simulations continues to increase as multimodel, multiphysics, and multi-institutional projects become widespread. A goal of component - based software engineering in such large-scale simulations is to help manage this complexity by enabling better interoperability among various codes that have been independently developed by different groups. The Common Component Architecture (CCA) Forum is defining a component architecture specification to address the challenges of high-performance scientific computing. In addition, several execution frameworks, supporting infrastructure, and general-purpose components are being developed. Furthermore, this group is collaborating with others in the high-performance computing community to design suites of domain-specific component interface specifications and underlying implementations. © Springer-Verlag Berlin Heidelberg 2006.

Electrostress diffusion coupling model for polyelectrolyte gels (vol 38, pg 1349, 2005)

MACROMOLECULES 2005年第17期38卷 7528-7528页

To describe the deformation dynamics of polyelectrolyte gel, we formulate the electrostress diffusion coupling model. The model describes the interplay of the deformation of gel, permeation of water, and the transport of ions. The model gives a microscopic expression for the Onsager coefficient and allows us to discuss the effect of ionic radius. The model is then applied to the bending dynamics of a thin strip of ionic gels under stepwise application of electric field. The model qualitatively explains the relaxation behavior of an ionic gel (Nafion 117) for various kinds of ions including large counterions such as TEA⁺ (tetraethylammonium).

High-throughput proteome annotation refers to the activity of extracting information from all proteins in a particular organism using bioinformatics software on a high performance computing platform such as the grid. The Encyclopedia of Life (EOL) project [1] aims to catalog all proteins in all species for public benefits using an Integrative Genome Annotation Pipeline [2] (iGAP). The intrinsic complexity of the pipeline makes iGAP an ideal life sciences application to drive grid software development. It is a flagship application for the TeraGrid project [3]. The deployment of iGAP on the grid using grid middleware and mediator software has been described previously [4]. The heterogeneous and distributed computing environment on the grid requires an interactive user interface where jobs may be submitted and monitored. Here we describe our international collaborative effort in creating a grid portal solution for grid computing in life sciences under the auspices of PRAGMA [5]. Specifically, the development of GridMonitor for interactive monitor of iGAP workflow, and the use of a GridSpeed [6] generated iGAP application portal are described. The portal solution was part of the EOL demonstration at Supercomputing 2003 (SC'03) [7], where resources from 6 institutions on 5 continents are utilized to annotate more than 36,000 proteins from various species. It is a testimony to the necessity and expediency for international collaboration in an increasingly global grid computational environment to advance life sciences research. © Springer-Verlag Berlin Heidelberg 2005.

Density-functional calculations and eigenchannel analyses for electron transport in Al and Si atomic wires

We perform first-principles calculations of the conductance of Al and Si atomic wires between jellium electrodes using the wave-function matching method combined with the density-functional theory. The calculated conductances for single-line and double-line atomic wires exhibit rich variation depending on the detailed atomic structure and the chemical difference between the constituent elements. The origin of the similarity and dissimilarity between Al and Si atomic wires is unequivocally clarified by our eigenchannel analyses of the wave functions and transmission probabilities obtained and by the calculated energy bands of the corresponding infinite-length atomic wires. We also find that the conductance of single-line Al wires increases upon stretching of the wires. This is due to peculiar features of the electron states of atomic wires consisting of group III or group IV atoms. The result is consistent with the observed conductance of Al wires.

Annual IEEE Symposium on Foundations of Computer science

In this work, we look back into the proof of the PCP theorem, with the goal of finding new proofs that are "more combinatorial" and arguably simpler. For that, we introduce the notion of an assignment tester, which is a strengthening of the standard PCP verifier, in the following sense. Given a statement and an alleged proof for it, while the PCP verifier checks correctness of the statement, the assignment-tester checks correctness of the statement and the proof. This notion enables composition that is truly modular, i.e., one can compose two assignment-testers without any assumptions on how they are constructed. A related notion was independently introduced in (Ben-Sasson et. al. STOC 04). We provide a toolkit of (non-trivial) generic transformations on assignment testers. These transformations may be interesting in their own right, and allow us to present the following two main results: 1. The first is a new proof of the PCP theorem. This proof relies on a rather weak assignment tester given as a "black box". From this, we construct combinatorially the full PCP. An important component of this proof is a new combinatorial aggregation technique (i.e., a new transformation that allows the verifier to read fewer, though possibly longer, "pieces" of the proof). An implementation of the black-box tester can be obtained from the algebraic proof techniques that already appear in L. Babai et al., 1991 and U. Feige et al., 1991. Obtaining a combinatorial implementation of this tester would give a purely combinatorial proof for the PCP theorem, which we view as an interesting open problem. 2. Our second construction is a "standalone" combinatorial construction showing NP /spl sube/ PCP (S. Arora et al., 1998). This implies, for example, that approximating max-SAT is quasi-NP-hard. This construction relies on a transformation that makes an assignment tester "oblivious": so that the proof locations read are independent of the statement that is being proven. This eliminates, in

Aboard current ships, such as the DDG 51, engineering control and damage control activities are manpower intensive. It is anticipated that, for future combatants, the workload demand arising from operation of systems under conditions of normal steaming and during casualty response will need to be markedly reduced via automated monitoring, autonomous control, and other technology initiatives. Current DDG 51 class ships can be considered as a manpower baseline and under Condition III typical engineering control involves seven to eight watchstanders at manned stations in the Central Control Station, the engine rooms and other machinery spaces. In contrast to this manning level, initiatives such as DD 21 and the integrated engineering plant (IEP) envision a partnership between the operator and the automation system, with more and more of the operator's functions being shifted to the automation system as manning levels decrease. This paper describes some human systems integration studies of workload demand reduction and, consequently, manning reduction that can be achieved due to application of several advanced technology concepts. advanced system concept studies in relation to workload demand are described and reviewed including. Piecemeal applications of diverse automation and remote control technology concepts to selected high driver tasks in current DDG 51 activities. development of the reduced ship's crew by virtual presence system that will provide automated monitoring and display to operators of machinery health, compartment conditions, and personnel health. The IEP envisions the machinery control system as a provider of resources that are used by various consumers around the ship. Resource needs and consumer priorities are at all times dependent upon the ship's current mission and the availability of equipment pawnbrokers.

Energies of interband optical transition in InGaAs/InAlAs multi-quantum well (MQW) structures were studied using one undoped and two n-type modulation-doped specimens grown by MBE. Step-like allowed transitions were observed and identified between 120 K and 330 K. In a 10 nm-thick quantum well (QW), three typical eigen states of the conduction subband (CS) were discriminated in a 0.52 eV range of energy in the QW. Doped and undoped MQW specimens had almost the same transition energies from the valence subband to the CSs. In a highly doped specimen of 1.5/spl times/10/sup 12/ cm/sup -2/ electrons per QW, the inter-ground-state optical transition was prohibited by the band filling effect. In the low doped specimen of 5/spl times/10/sup 11/ cm/sup -2/ electrons per QW, however, the same transition below the Fermi energy level was observed at 120 K. Moreover, localized states or an impurity band with an activation energy of 25 meV associated with the ground and the second higher CSs, were observed. No localized state was observed in the undoped ones.

Dispersion relation and optical transmittance of a hexagonal photonic crystal slab

Physical Review B 2001年第12期63卷 125107-125107页

作者： T. Ochiai K. Sakoda Research Institute for Electronic Science Hokkaido University Sapporo 060-0812 Japan Research and Development Applying Advanced Computational Science and Technology Japan Science and Technology Corporation Tokyo 102-0081 Japan

The dispersion relation and the optical transmittance of a two-dimensional photonic crystal composed of the hexagonal array of cylindrical air holes fabricated in a dielectric slab were analyzed by group theory and the numerical calculation based on the finite-difference time-domain method. The decay rate of the leaky modes that exist above the light line (the dispersion relation in air) in the band diagram was also evaluated, from which the absence of the coupling between certain internal eigenmodes and the external radiation field was shown. This phenomenon was related to symmetry mismatching by the group-theoretical argument. It was also shown that a certain leaky band has a quality factor as large as 3000 over its entire spectral range. These features as well as the opaque frequency regions due to symmetry mismatching were clearly demonstrated by the calculated optical transmission spectra.
