MS-120: Naviglia-Woncheck World War II Letters Home: A Family Separated by War

The collection consists of 31 letters or postcards by service men to loved ones at home. Nearly all of the letters are from members of the Naviglia-Woncheck extended family including the four Naviglia brothers: Louis (14 letters), John (one letter), James (one letter), Joseph (7 letters), and “Check” Woncheck (5 letters) the brother-in-law of their sister Anne. The collection also includes one letter from PFC James Faulkner to his sister and one letter from Pvt. David R. Curry to his cousin, Frances Faulkner, a card address to Ford Peters, a war ration book, a Draft Classification Notice for William Thomas Woncheck, Anne’s husband, and an uniform name badge for Sgt Woncheck.

MS-163: The Gettysburg Experience, Class of 1963

The collection includes printed materials from college sponsored programs, college publications, scrapbooks, correspondence between a student and her family, textbooks from the required course GE 201-202: Literary Foundations of Western Culture, numerous documents and artifacts from Greek life, athletics, student life, and academic programs and activities. The collection presents a helpful overview of the academic program and student life at the college during the early 1960s, and follows the interaction of class members with the college as active alumni, highlighting their service to the college, honors and awards received, and activities during class reunions. Of special interest are legacy statements written by class members reflecting on their time at the college and how those experiences shaped their careers and lives after graduation.

MS – 229: Gordon Haaland Personal Papers

This collection contains the personal papers of Gordon A. Haaland, produced and acquired during his many years as a college professor and as an administrator at the University of New Hampshire, at the University of Maine at Orono, and at Gettysburg College. What is striking about the material is how Haaland remained true to his academic background in social psychology, remaining current in the field and applying the theories of that discipline to the tasks and challenges that he faced as a college administrator and educational leader. The collection is organized into four series: Series I: Pre-Gettysburg College; Series II: Gettysburg College; Series III: A President’s Library; and Series IV: Personal and Family Special Collections and College Archives Finding Aids are discovery tools used to describe and provide access to our holdings.

MS-124: Samuel Simon Schmucker Bicentennial Celebration 1999

The official papers of the Schmucker Bicentennial Committee reside in the Archives at the Lutheran Theological Seminary at Gettysburg. This collection at the college contains the material retained by Gettysburg College representatives to the committee and internal college documents relating to the program events compiled by the Public Relations Office and the Office of Planned Giving. Of special interest is a review of a research effort conducted within the Office of College Relations to identify the descendants of Samuel Schmucker in order to invite them to the college for the birthday event. This research resulted in the creation of a large family genealogical chart containing the names of 131 descendent of Schmucker. The collection contains correspondence with and personal histories of some of the living descendants.

Conceptual servo technique for controlling tape drivers

Electronic speed control design maintains magnetic tape in close synchronism at the airborne and ground stationed devices. Use of the servo system during the record and reproduce modes results in the minimum amount of frequency distortion and flutter

Medial Superior Olivary Neurons Receive Surprisingly Few Excitatory and Inhibitory Inputs with Balanced Strength and Short-Term Dynamics

Neurons in the medial superior olive (MSO) process microsecond interaural time differences, the major cue for localizing low-frequency sounds, by comparing the relative arrival time of binaural, glutamatergic excitatory inputs. This coincidence detection mechanism is additionally shaped by highly specialized glycinergic inhibition. Traditionally, it is assumed that the binaural inputs are conveyed by many independent fibers, but such an anatomical arrangement may decrease temporal precision. Short-term depression on the other hand might enhance temporal fidelity during ongoing activity. For the first time we show that binaural coincidence detection in MSO neurons may require surprisingly few but strong inputs, challenging long-held assumptions about mammalian coincidence detection. This study exclusively uses adult gerbils for in vitro electrophysiology, single-cell electroporation and immunohistochemistry to characterize the size and short-term plasticity of inputs to the MSO. We find that the excitatory and inhibitory inputs to the MSO are well balanced both in strength and short-term dynamics, redefining this fastest of all mammalian coincidence detector circuits

Hydra: A Parallel Adaptive Grid Code

We describe the first parallel implementation of an adaptive particle-particle, particle-mesh code with smoothed particle hydrodynamics. Parallelisation of the serial code, ``Hydra'', is achieved by using CRAFT, a Cray proprietary language which allows rapid implementation of a serial code on a parallel machine by allowing global addressing of distributed memory. The collisionless variant of the code has already completed several 16.8 million particle cosmological simulations on a 128 processor Cray T3D whilst the full hydrodynamic code has completed several 4.2 million particle combined gas and dark matter runs. The efficiency of the code now allows parameter-space explorations to be performed routinely using $64^3$ particles of each species. A complete run including gas cooling, from high redshift to the present epoch requires approximately 10 hours on 64 processors. In this paper we present implementation details and results of the performance and scalability of the CRAFT version of Hydra under varying degrees of particle clustering.Comment: 23 pages, LaTex plus encapsulated figure
