Temple Emanuel (Andover, Mass.) records, 1939-2001; and Part II (addendum), undated 1952-2004

Temple Emanuel was founded in 1920 in Lawrence, Massachusetts. It began by serving a small immigrant Jewish community that has since grown to an affluent and lively congregation of about 600 families. This growth occurred largely under the tenure of Rabbi Harry A. Roth, who lead the congregation from 1962 until 1990 and oversaw the temple’s move to Andover, Massachusetts. This collection includes correspondence, photographs, and sermons.

Beth Israel Hospital (Boston, MA) Records, undated, 1923, 1930-1964, 1988, 1991-1992

In 1916, the Jewish community of Boston established Beth Israel Hospital on Townsend Street in Roxbury to provide health care to immigrants in the area. Although accessible to everyone, the hospital provided Yiddish-speaking services for Eastern European Jewish immigrants and served kosher food, as well as conducted Jewish religious services. In 1928 the hospital entered into a teaching agreement with Harvard Medical School, Tufts University, and Simmons College. Shortly thereafter, the hospital moved to its current location in the Longwood area of Boston and expanded to a 220-bed operation. During 1935-1936, at the height of the Depression, Beth Israel spent 1.5 million dollars in free patient care and was only one of two local hospitals to offer health care to people on welfare. In 1996, Beth Israel Hospital merged with Deaconess Medical Center and became Beth Israel Deaconess Medical Center. This collection contains reports, pamphlets and hospital publications.

Hebrew College collection, 1928-1996

Louis Hurwich, then superintendent of the Bureau of Jewish Education of Boston, founded Hebrew Teacher’s College in 1921. Hurwich was concerned about Jewish teachers leaving the field of Jewish education for other professions and sought an educational system that promoted Hebrew literacy at all levels. Hebrew Teacher’s College was also responsible for maintaining Hebrew High School (Prozdor), located at 14 Crawford Street in Roxbury, Massachusetts. Those students who graduated from the high school could matriculate to Hebrew Teacher’s College without having to take an exam. In 1943, the high school offered Talmud classes in addition to its regular curriculum, with studies in the Bible, Hebrew, Jewish History, and codes and customs. In 2002, the College moved to its current location in Newton, Massachusetts. One year later, it opened its Rabbinical School. This collection contains brochures, catalogs, commencement addresses, event fliers, invitations, pamphlets and publications.

Myer Starr, memoirs undated

Myer Starr was born in Dmitrovka in the Ukraine, which was then part of Russia. As a child he was apprenticed to a tailor and later a bakery before he began work at a dry goods store at the age of 11. After his mother died, Starr and his younger brother crossed the border into Germany and then immigrated to the United States. Starr and his brother sailed on the "Kleist" into New York in February 1913. From there, they traveled to a sister's house in Malden, Massachusetts. Myer later married and had two sons, graduates of Harvard College and Tufts University.

Modern computed tomography techniques in stroke management

Technological development of fast multi-sectional, helical computed tomography (CT) scanners has allowed computed tomography perfusion (CTp) and angiography (CTA) in evaluating acute ischemic stroke. This study focuses on new multidetector computed tomography techniques, namely whole-brain and first-pass CT perfusion plus CTA of carotid arteries. Whole-brain CTp data is acquired during slow infusion of contrast material to achieve constant contrast concentration in the cerebral vasculature. From these data quantitative maps are constructed of perfused cerebral blood volume (pCBV). The probability curve of cerebral infarction as a function of normalized pCBV was determined in patients with acute ischemic stroke. Normalized pCBV, expressed as a percentage of contralateral normal brain pCBV, was determined in the infarction core and in regions just inside and outside the boundary between infarcted and noninfarcted brain. Corresponding probabilities of infarction were 0.99, 0.96, and 0.11, R² was 0.73, and differences in perfusion between core and inner and outer bands were highly significant. Thus a probability of infarction curve can help predict the likelihood of infarction as a function of percentage normalized pCBV. First-pass CT perfusion is based on continuous cine imaging over a selected brain area during a bolus injection of contrast. During its first passage, contrast material compartmentalizes in the intravascular space, resulting in transient tissue enhancement. Functional maps such as cerebral blood flow (CBF), and volume (CBV), and mean transit time (MTT) are then constructed. We compared the effects of three different iodine concentrations (300, 350, or 400 mg/mL) on peak enhancement of normal brain tissue and artery and vein, stratified by region-of-interest (ROI) location, in 102 patients within 3 hours of stroke onset. A monotonic increasing peak opacification was evident at all ROI locations, suggesting that CTp evaluation of patients with acute stroke is best performed with the highest available concentration of contrast agent. In another study we investigated whether lesion volumes on CBV, CBF, and MTT maps within 3 hours of stroke onset predict final infarct volume, and whether all these parameters are needed for triage to intravenous recombinant tissue plasminogen activator (IV-rtPA). The effect of IV-rtPA on the affected brain by measuring salvaged tissue volume in patients receiving IV-rtPA and in controls was investigated also. CBV lesion volume did not necessarily represent dead tissue. MTT lesion volume alone can serve to identify the upper size limit of the abnormally perfused brain, and those with IV-rtPA salvaged more brain than did controls. Carotid CTA was compared with carotid DSA in grading of stenosis in patients with stroke symptoms. In CTA, the grade of stenosis was determined by means of axial source and maximum intensity projection (MIP) images as well as a semiautomatic vessel analysis. CTA provides an adequate, less invasive alternative to conventional DSA, although tending to underestimate clinically relevant grades of stenosis.

Field emission properties of carbon nanotube arrays with defects and impurities

Field emission from carbon nanotubes (CNTs) in the form of arrays or thin films give rise to several strongly correlated process of electromechanical interaction and degradation. Such processes are mainly due to (1) electron-phonon interaction (2) electromechanical force field leading to stretching of CNTs (3) ballistic transport induced thermal spikes, coupled with high dynamic stress, leading to degradation of emission performance at the device scale. Fairly detailed physics based models of CNTs considering the aspects (1) and (2) above have already been developed by these authors, and numerical results indicate good agreement with experimental results. What is missing in such a system level modeling approach is the incorporation of structural defects and vacancies or charge impurities. This is a practical and important problem due to the fact that degradation of field emission performance is indeed observed in experimental I-V curves. What is not clear from these experiments is whether such degradation in the I-V response is due to dynamic reorientation of the CNTs or due to the defects or due to both of these effects combined. Non-equilibrium Green’s function based simulations using a tight-binding Hamiltonian for single CNT segment show up the localization of carrier density at various locations of the CNTs. About 11% decrease in the drive current with steady difference in the drain current in the range of 0.2-0.4V of the gate voltage was reported in literature when negative charge impurity was introduced at various locations of the CNT over a length of ~20nm. In the context of field emission from CNT tips, a simplistic estimate of defects have been introduced by a correction factor in the Fowler-Nordheim formulae. However, a more detailed physics based treatment is required, while at the same time the device-scale simulation is necessary. The novelty of our present approach is the following. We employ a concept of effective stiffness degradation for segments of CNTs, which is due to structural defects, and subsequently, we incorporate the vacancy defects and charge impurity effects in the Green’s function based approach. Field emission induced current-voltage characteristics of a vertically aligned CNT array on a Cu-Cr substrate is then simulated using a detailed nonlinear mechanistic model of CNTs coupled with quantum hydrodynamics. An array of 10 vertically aligned and each 12 m long CNTs is considered for the device scale analysis. Defect regions are introduced randomly over the CNT length. The result shows the decrease in the longitudinal strain due to defects. Contrary to the expected influence of purely mechanical degradation, this result indicates that the charge impurity and hence weaker transport can lead to a different electromechanical force field, which ultimately can reduce the strain. However, there could be significant fluctuation in such strain field due to electron-phonon coupling. The effect of such fluctuations (with defects) is clearly evident in the field emission current history. The average current also decreases significantly due to such defects.
