No full textWhittier House scrapbooks document Whittier House programs, events, and anniversary celebrations through newspaper clippings, lecture fliers, newsletters, event programs, and ticket stubs. Newspaper clippings are primarily from the Jersey Journal. There is also Whittier House fundraising materials, including pamphlets, appeal letters, brochures, and postcards. The Whittier House Social Settlement, the first settlement house in New Jersey, was established in Jersey City, N.J. (Hudson County) in 1894. Founded by Cornelia Foster Bradford, who would remain with the organization as headworker until 1926, Whittier House was based on the settlement house, Toynbee Hall, in England. Whittier House provided various recreational and educational programs, along with much needed social services, for the immigrant populations of Jersey City. Many of these successful services were used as models for large-scale social reform movements through the state. In 1935, the Whittier House was taken over by the Boys' Club of Jersey City
Production of a composite Higgs boson
No full textWe present a model-independent prescription for computing the gluon fusion production rate of a composite Higgs boson, which arises as a pseudo-Nambu-Goldstone boson, using effective Lagrangians. The calculation incorporates three different effects due to the composite nature of the Higgs, some of which were neglected previously. We apply the prescription to models with and without the collective breaking mechanism. In sharp contrast with the case of a fundamental Higgs scalar, the rate only depends on the decay constant f and is not sensitive to masses of new particles. After including electroweak constraints, there is a substantial reduction in the rate, in the range of 10%-30% or greater. © 2011 American Physical Society

Use of Fourier-Transform Infrared Spectroscopy for the Diagnosis of Failure of Transfer of Passive Immunity and Measurement of Immunoglobulin Concentrations in Horses
No full textBackground: The economic, accurate, and rapid screening of foals for failure of transfer of passive immunity (FPT) is essential to ensure timely intervention. Hypothesis: Infrared (IR) spectroscopy of foal sera and pattern recognition may be used to diagnose FPT and quantify serum IgG. Samples: Sera from 194 foals (24–72 hours) with serum immunoglobulin G (IgG) concentrations determined previously by radial immunodiffusion assay (RID) were used. Methods: IR spectra were recorded for the serum samples, and the data were randomly divided into training and independent test sets, each containing both FPT-positive (IgG <400 mg/dL) and non-FPT samples. A genetic optimal region selection algorithm and linear discriminant analysis were used to partition the training spectra, and the resulting classifier was then validated by comparing the IR-predicted FPT status for each of the test samples to that provided by the RID IgG assay. A quantitative IR-based assay for IgG was developed using partial least squares (PLS) and validated by testing its ability to predict IgG concentrations. Results: Specificity, sensitivity, and accuracy for the combined data were 92.5, 96.8, and 95.9%, respectively. Corresponding positive (88.1%) and negative predictive (98.0%) values determined a success rate of 95–97% as compared to RID-based IgG concentrations. The IR-based quantitative assay yielded correlation coefficients for IR spectroscopy versus RID-based IgG concentrations of 0.90 and 0.86 for the training and test sets, respectively. Conclusions and Clinical Importance: The overall performance of the IR-based test was similar to that of the colorimetric assay and was superior and more economic than other available tests.Christopher B.

MitigatePlus: Research for low-emission food systems
No full textMitigatePlus: Research for Low-Emission Food Systems is one of the Research Initiatives in CGIAR’s new research portfolio that will deliver science and innovation to transform food, land, and water systems in a climate crisis. Mitigate+ focuses on reducing greenhouse gas emissions from food systems and the predicted consequences of climate change on sustainable development and social equity. The initiative expects to help countries reduce emissions by 1.1 gigatons (6.5%) by 2030. An estimated 8 million people will benefit from these reduced emissions and from the associated co-benefits over the Initiative’s ten-year lifespan.Non-PR1 Fostering Climate-Resilient and Sustainable Food Supply; IFPRI1EPT

A multi-filter system for speech enhancement under low signal-to-noise ratios
No full textIn this paper, the problem of deteriorating performance of speech recognition under very low signal-to-noise ratios (SNR) is considered. In particular, for a given pre-trained speech recognizer and for a finite set of speech commands, we show that popular noise reduction methods have a mixed performance in speech recognition accuracy under very low SNR. Although most noise reduction methods are attempting to reduce speech distortion or to increase noise suppression, it does not necessarily improve speech recognition accuracy very much due to the complexity of the recognizer. We propose a new hybrid algorithm to optimize on the speech recognition accuracy directly by mixing different noise reduction methods together. We show that this method can indeed improve the accuracy significantl

474: lighting and thermal performance of innovative shading devices: new insights into their aesthetics and control in a Mediterranean climate
No full textWith a view towards minimising energy demand for cooling and artificial lighting in buildings, this paper evaluates innovative shading devices and how they can balance a generous degree of control mastering seasonal natural light with thermal gains in a typical Mediterranean climate such as Malta. The study evaluates the potential success (or failure) of such shading devices, from both their aesthetic and functional perspectives, as part of a passive design strategy adopted by the architect. Through environmental design and solar geometry, experimental simulations were generated in architectural science modelling software package Ecotect© developed by Andrew Marsh. Moreover a novel computer model termed Solar Control© was developed by the authors in order to assist architects at an early stage during design.peer-reviewe
A review of developments in the electrodeposition of tin
No full textThe importance of tin and its electrodeposition are summarised and the scope for plating tin is outlined. Established applications of electroplated tin include corrosion protection, electronics fabrication and cooking utensils. The past 20 years have seen developments in the science and technology of tin plating, including research into nanostructured deposits, adoption of environmentally friendly methanesulfonic acid baths and more ambitious coatings including multi-layers and composites. Our ability to tailor deposit structure and composition has been improved by newer electrolytes, pulse plating and electrolyte additives. The diversity of tin applications has extended to lithium batteries using newer structures (such as composites, multi-layers and nanostructures), electrical control (e.g., pulsed current) and relative bath/electrode movement (including the use of rotating electrodes). Electrochemical aspects of modern tin deposition are illustrated by data fromthe authors' laboratory which highlights the versatility of methanesulfonic acid electrolytes. A wide range of deposit morphology, colour and surface finish are possible by the use of suitable addition agents and control of electrode/electrolyte movement and operating conditions. Subject areas needing further research work are identified
