Ab Initio Identification of the Nitrogen Diffusion Mechanism in Silicon

Stoddard, Nathan; Pichler, Peter; Duscher, Gerd; Windl, Wolfgang ( 2005-07-06 )

In this Letter, we present ab initio results identifying a new diffusion path for the nitrogen pair complex in silicon, resulting in an effective diffusivity of 67exp (-2.38 eV/kT) cm^2/s. This nudged elastic band result ...

Ab initio Ti-Zr-Ni phase diagram predicts stability of icosahedral TiZrNi quasicrystals

Hennig, R. G.; Carlsson, A. E.; Kelton, K. F.; Henley, C. L. ( 2005-04-04 )

The ab initio phase diagram determines the energetic stability of the icosahedral TiZrNi quasicrystal. The complete ab initio zero-temperature ternary phase diagram is constructed from the calculated energies of the ...

Ab-Initio Calculations of the Energetics and Kinetics of Defects and Impurities in Silicon

Windl, Wolfgang ( 2006 )

In this paper, we discuss concepts and examples of ab-initio calculations to understand the energetics and kinetics of defects and impurities in silicon. We focus on how to determine equilibrium distributions and diffusion ...

Ab-Initio Modeling of Point Defects, Impurities and Diffusion in Silicon

Windl, Wolfgang ( 2008-10 )

We have revisited the first-principles calculation of the diffusion coefficient for nitrogen monomers and dimers, both within the dissociative and the direct pair-diffusion picture, using density-functional theory and ...

Abraham, Isaac, and Britten: Conflict and Reconciliation in War Requiem

Strader, Nikola Dale, 1965- ( 2013-10-26 )

Absence of gemin5 from SMN complexes in nuclear Cajal bodies

Hao, Le thi; Fuller, Heidi R.; Lam, Le Thanh; Le, Thanh T.; Burghes, Arthur H. M.; Morris, Glenn E. ( 2007-07-18 )

Background: Spinal muscular atrophy is caused by reduced levels of the survival of motor neurons (SMN) protein. SMN is found in large complexes with Sm proteins and at least eight other proteins, including seven "gemins". ...

Absolute Photoionization Cross Section Measurements of O II Ions from 29.7 to 46.2 eV

Nahar, Sultana Nurun; Aguilar, A.; Covington, A. M.; Hinojosa, G.; Phaneuf, R. A.; Alvarez, I.; Cisneros, C.; Bozek, J. D.; Dominguez, I.; Sant'Anna, M. M.; Schlachter, A. S.; McLaughlin, B. M. ( 2003-06 )

Absolute photoionization cross sections have been measured for a mixture of ground-state and metastable O II (O^+) ions at photon energies ranging from 29.9 to 46.0 eV (414.7 to 269.5 Å). All measurements were performed ...

Abundance Anomalies and Rotational Evolution of Low-Mass Red Giants: A Maximal Mixing Approach

Chanamé, Julio; Pinsonneault, Marc; Terndrup, Donald M. ( 2005-09-20 )

We use a fully self-consistent evolutionary code to follow the rotational evolution of low-mass red giants, making a comprehensive attempt to assess the role of rotationally induced mixing in the development of abundance ...

The Abundance of C_7^- in Diffuse Clouds

Ruffle, Deborah P.; Bettens, R. P. A.; Terzieva, Radoslava; Herbst, Eric ( 1999-10-01 )

It has recently been proposed that C_7^- is a carrier of five of the numerous diffuse interstellar bands. In this paper, we report an attempt to reproduce the required abundance of C_7^- relative to hydrogen of n(C_7^-) ~ ...

ACADEMIC USE OF MOBILE TECHNOLOGY BY STUDENT ATHLETES AT A LARGE DIVISION I MIDWESTERN UNIVERSITY: A GROUNDED THEORY STUDY

Kraft, Nicole ( 2018-05-18 )

The purpose of this grounded theory study was to examine the process by which student-athletes at a large Division I Midwestern university use mobile technology for academic purposes, and develop a theory about how they ...

Accounting for uncertainty in ecological analysis: the strengths and limitations of hierarchical statistical modeling

Cressie, Noel; Calder, Catherine A.; Clark, James S.; Ver Hoef, Jay M.; Wikle, Christopher K. ( 2009-04 )

Analyses of ecological data should account for the uncertainty in the process(es) that generated the data. However, accounting for these uncertainties is a difficult task, since ecology is known for its complexity. Measurement ...

Acetyl-L-Carnitine in Attention-Deficit/Hyperactivity Disorder: A Multi-Site, Placebo-Controlled Pilot Trial
