The Legacy of Charles Henry Huber, Class of 1892: A Half Century of Service to Gettysburg College

In the common room of Huber Hall, there hangs high on the wall a dingy looking portrait of an older gentleman, dressed in a dark suit with round-framed glasses and graying hair. Beneath this portrait framed in faded gold is a small, tarnished, black plaque that gives a name to this curious looking man and briefly describes some of his accomplishments. From this portrait located above a small television, the Reverend Charles Henry Huber looks out over what used to be the lobby of the Gettysburg Academy, which was housed in a building where he spent much of his professional life; a building that would one day take on his name. Looking out into the common room of what has been transformed into a first year residence hall, “Huber” can see many of the changes that have come to his building and the college where he spent much of his life. Where a grand piano once stood toward the end of his time at the Academy, two rarely used foosball tables now sit; where a brick fireplace once housed its fair share of crackling fires on a snowy day, the metal doors to an elevator now open and close on a daily basis. Students who once crowded around the fireplace to listen to a radio broadcast now crowd around a television to watch new episodes of Grey’s Anatomy and other popular T.V. shows. From his retirement in 1940 to his death in 1951, and for many years after, Huber\u27s portrait has seen many changes to both Huber all and the students who now live there from his portrait on the wall. The story of his half century of service to the college remains the same, although there are few people who could tell even a portion of it today.

Sources of Data for Micro Level Planning from Village Level Institutions: An Overview

A study was conducted to compile the databases related to agricultural development available at the local level that could be used for micro level planning. For this purpose, the details of legacy databases in offices of the department of agriculture and local self government institutions were collected to find out the frequency of updating information and completeness of data. Further investigation was done to find out the static and dynamic nature of legacy registers and how best they could be used in building up a comprehensive database for facilitating micro level planning in agriculture

First-Principles Study of Chemisorption of Oxygen and Aziridine on Graphitic Nanostructures

Using ab initio plane wave pseudopotential calculations, we study the energetics and structure of adsorbed linear arrays of oxygen and aziridine on carbon nanotubes, graphitic ribbons, and graphene sheets. Chemisorption of arrays of O or NH causes splitting of the CC bond and local deformation of the graphitic structures. The (3,3) nanotube cross section assumes a teardrop-like shape, while graphene sheets warp into a new local geometry around the chemisorbed molecules. The interior of a (3,3) nanotube is less prone to oxidation than the exterior because of steric effects. A zigzag (6,0) nanotube is less reactive and thus chemically more stable than an armchair (3,3) nanotube. The results suggest a partial explanation for the experimentally observed selective etching of metallic carbon nanotubes

Efficient Optimization of Loops and Limits with Randomized Telescoping Sums

We consider optimization problems in which the objective requires an inner loop with many steps or is the limit of a sequence of increasingly costly approximations. Meta-learning, training recurrent neural networks, and optimization of the solutions to differential equations are all examples of optimization problems with this character. In such problems, it can be expensive to compute the objective function value and its gradient, but truncating the loop or using less accurate approximations can induce biases that damage the overall solution. We propose randomized telescope (RT) gradient estimators, which represent the objective as the sum of a telescoping series and sample linear combinations of terms to provide cheap unbiased gradient estimates. We identify conditions under which RT estimators achieve optimization convergence rates independent of the length of the loop or the required accuracy of the approximation. We also derive a method for tuning RT estimators online to maximize a lower bound on the expected decrease in loss per unit of computation. We evaluate our adaptive RT estimators on a range of applications including meta-optimization of learning rates, variational inference of ODE parameters, and training an LSTM to model long sequences

Union Organization in Great Britain

Union membership and density in Britain has experienced substantial decline since 1979. The fall in private sector membership and density has been much greater than in the public sector. The size of the union sector, measured by employer recognition, has shrunk. Membership decline has been accompanied by financial decline. Much of the decline occurred before 1997, under Conservative governments. Since 1997 and the return of a Labour government, the position has in some respects stabilized. Currently, unions have a substantially reduced economic impact, but a continued, if limited, role in workplace communication and grievance handling, often as part of a voice regime including non union elements.British trade unions, union structure, union membership

Fluctuations at the blue edge of saturated wind lines in IUE spectra of O-type stars

We examine basic issues involved in synthesizing resonance-line profiles from 1-D, dynamical models of highly structured hot-star winds. Although these models exhibit extensive variations in density as well as velocity, the density scale length is still typically much greater than the Sobolev length. The line transfer is thus treated using a Sobolev approach, as generalized by Rybicki & Hummer (1978) to take proper account of the multiple Sobolev resonances arising from the nonmonotonic velocity field. The resulting reduced-Lambda-matrix equation describing nonlocal coupling of the source function is solved by iteration, and line profiles and then derived from formal solution integration using this source function. The more appropriate methods that instead use either a stationary or a structured, local source function yield qualitatively similar line-profiles, but are found to violate photon conservation by 10 percent or more. The full results suggest that such models may indeed be able to reproduce naturally some of the qualitative properties long noted in observed UV line profiles, such as discrete absorption components in unsaturated lines, or the blue-edge variability in saturated lines. However, these particular models do not yet produce the black absorption troughs commonly observed in saturated lines, and it seems that this and other important discrepancies (e.g., in acceleration time scale of absorption components) may require development of more complete models that include rotation and other 2-D and/or 3-D effects
