Production Systems Involving Stocker Cattle and Soft Red Winter Wheat

A three year study at the Livestock and Forestry Research Station near Batesville, Arkansas evaluated production systems involving stocker cattle and soft red winter wheat. Grazing of soft red winter wheat forage from October through February followed by harvesting wheat grain or grazing through April with stocker cattle offers an alternative to conventional farming. Soft red winter wheat, when planted by September 15, produces an ample supply of high-quality forage that supports rapid growth of stocker cattle during October through April. Net income from stocker cattle averaged over $100 per acre. A normal wheat grain crop can also be harvested. These alternative production systems could increase the agricultural income by over$75,000,000 per year if 750,000 acres of wheat are grazed

Address by Professor David B. Wilkins, Washington and Lee University School of Law Commencement Exercises, May 5, 2018

Professor David B. Wilkins of Harvard Law School delivered an invited address to the Washington and Lee Law Class of 2018 at their commencement ceremony. Following the conclusion of the ceremony, Dean Brant Hellwig secured Professor Wilkins\u27 gracious permission to publish the address in the Washington and Lee Law Review, and provides a written introduction to Professor Wilkins\u27 speech here. Professor Wilkins undertook considerable research in crafting a commencement address that incorporated several prominent figures from the history W&L Law and the University. His speech highlighted not only the contributions of George Washington and Robert E. Lee, for whom the University is named, but also two of the Law School’s most prominent alumni: John W. Davis, former Solicitor General of the United States, President of the American Bar Association, and founder of the Davis Polk law firm; and Supreme Court Justice Lewis F. Powell, Jr

W&L Law Fall Scholarship Celebration 2019

On October 15, 2019, the Washington and Lee Law Library hosted the third bi-annual W&L Law Fall Scholarship Celebration. The event was co-sponsored by the Frances Lewis Law Center and took place in the Law Library\u27s main reading room from 4:30 to 6:30 p.m. On display were dozens of scholarly articles, books, and chapters authored by the W&L Law faculty and student body during 2018 and 2019, with hundreds of additional works accessible online through the Scholarly Commons institutional repository. Faculty, librarians, staff, and administrators mingled with law students over hors d\u27oeuvres and wine to peruse the formidable scholarly output of the W&L Law community. Spouses, alumni, faculty from W&L\u27s undergraduate campus, and others with ties to the University were also in attendance. Brant J. Hellwig, dean of W&L Law, and Christopher B. Seaman, director of the Frances Lewis Law Center, provided welcoming remarks introduced by W&L Law Library director Alex Zhang. The event program, which includes a list of the scholarship on display, is available to download in PDF. Photos taken at the event are also available to view in the W&L Law Scholarly Commons Image Gallery

Child language documentation: The sketch acquisition project

This paper reports on an on-going project designed to collect comparable corpus data on child language and child-directed language in under-researched languages. Despite a long history of cross-linguistic research, there is a severe empirical bias within language acquisition research: Data is available for less than 2% of the world's languages, heavily skewed towards the larger and better-described languages. As a result, theories of language development tend to be grounded in a non-representative sample, and we know little about the acquisition of typologically-diverse languages from different families, regions, or sociocultural contexts. It is very likely that the reasons are to be found in the forbidding methodological challenges of constructing child language corpora under fieldwork conditions with their strict requirements on participant selection, sampling intervals, and amounts of data. There is thus an urgent need for proposals that facilitate and encourage language acquisition research across a wide variety of languages. Adopting a language documentation perspective, we illustrate an approach that combines the construction of manageable corpora of natural interaction with and between children with a sketch description of the corpus data – resulting in a set of comparable corpora and comparable sketches that form the basis for cross-linguistic comparisons

Quantum optical versus quantum Brownian motion master-equation in terms of covariance and equilibrium properties

Structures of quantum Fokker-Planck equations are characterized with respect to the properties of complete positivity, covariance under symmetry transformations and satisfaction of equipartition, referring to recent mathematical work on structures of unbounded generators of covariant quantum dynamical semigroups. In particular the quantum optical master-equation and the quantum Brownian motion master-equation are shown to be associated to $\mathrm{U(1)}$ and $\mathrm{R}$ symmetry respectively. Considering the motion of a Brownian particle, where the expression of the quantum Fokker-Planck equation is not completely fixed by the aforementioned requirements, a recently introduced microphysical kinetic model is briefly recalled, where a quantum generalization of the linear Boltzmann equation in the small energy and momentum transfer limit straightforwardly leads to quantum Brownian motion.Comment: 11 pages, latex, no figures, slight changes and a few references added, to appear in J.

Quantum data processing and error correction

This paper investigates properties of noisy quantum information channels. We define a new quantity called {\em coherent information} which measures the amount of quantum information conveyed in the noisy channel. This quantity can never be increased by quantum information processing, and it yields a simple necessary and sufficient condition for the existence of perfect quantum error correction.Comment: LaTeX, 20 page

Evaluation of Small Grain Forage Crops and Cultivars of Soft Red Winter Wheat for Stocker Cattle

Use of small grain forage crops for stocker cattle production was extensively evaluated in two separate three-year research projects at the Livestock and Forestry Branch Research Station near Batesville, Ark. The first section of this Research Report presents results of a study in which 216 commercial crossbred steers (Avg. body weights 463 lb) grazed forage of wheat, oats, rye, ryegrass, wheat + rye, wheat + ryegrass, rye + ryegrass, and wheat + rye + ryegrass during the winter and spring months from 1999 through 2002. Grazing of these forages during the winter and spring provides excellent gains in stocker cattle and could increase the agricultural income for the state by over 100 million dollars per year

Position Measurement for a Relativistic Particle: Restricted-Path-Integral Analysis

Measurements of the position of a relativistic particle is considered in the framework of the Restricted-Path-Integral (RPI) approach. The amplitude describing such a measurement is shown to be exponentially small outside the light cone of the space-time point corresponding to the measurement output, in a qualitative agreement with the Hellwig and Kraus' postulate of relativistic state reduction. Theory of the measurement including the probability distribution for different measurement outputs is suggested. It is shown that correct theory does not exist (for arbitrary initial states) if the error of the measurement is less than the Compton length. The physical reason is that the picture of measurement is destroyed in this case by pair creation.Comment: 12 pages, LATE
