A system for managing critical knowledge for accelerator subsystems: Pansophy (2002)

Accelerator development and construction projects often intentionally push the envelope of well-established technical performance and manageable complexity. In addition, the desire for efficient retention and exploitation of accumulated experience across the multi-decade life cycles of major installations calls for a robust yet user-friendly knowledge management system. To meet these needs, we are deploying a new web-based system at Jefferson Lab: Pansophy. This system is a custom integration of several commercial software utilities, DocuShare/sup TM/, ColdFusion/sup TM/, Matlab/sup TM/, Ingres/sup Tm/, and common desktop programs. Users of the system range from process managers, shop-floor technicians, and test engineers to after-the-fact data miners and operations staff. The system integrates important quality assurance elements of procedural control, automated data accumulation into a secured central database, prompt and reliable data query and retrieval, and online analysis tools, all accessed by users via their platform-independent web browsers. A system overview, a completed pilot project, and implementation experience to date will be presented.
Treatment with orthophosphoric acid enhances the thermal stability of the piezoelectricity in low-density polyethylene ferroelectrets (2012)

Ferroelectrets have been fabricated from low-density polyethylene (LDPE) films by means of a template-based lamination. The temperature dependence of the piezoelectric d33 coefficient has been investigated. It was found that low-density polyethylene ferroelectrets have rather low thermal stability with the piezoelectric coefficient decaying almost to zero already at 100 °C. This behavior is attributed to the poor electret properties of the polyethylene films used for the fabrication of the ferroelectrets. In order to improve the charge trapping and the thermal stability of electret charge and piezoelectricity, LDPE ferroelectrets were treated with orthophosphoric acid. The treatment resulted in considerable improvements of the charge stability in LDPE films and in ferroelectret systems made from them. For example, the charge and piezoelectric-coefficient decay curves shifted to higher temperatures by 60 K and 40 K, respectively. It is shown that the decay of the piezoelectric coefficient in LDPE ferroelectrets is governed by the relaxation of less stable positive charges. The treatment also leads to noticeable changes in the chemical composition of the LDPE surface. Infrared spectroscopy reveals absorption bands attributed to phosphorus-containing structures, while scanning electron microscopy shows new island-like structures, 50–200 nm in diameter, on the modified surface.
Myocardial fibrosis: role of ventricular systolic pressure, arterial hypertension, and circulating hormones (1991)

The myocardium contains myocyte and non-myocyte cells. A disproportionate growth of the nonmyocyte cell population can alter myocardial structure and lead to pathologic hypertrophy. Myocardial fibrosis, the result of cardiac fibroblast growth or abnormal accumulation of fibrillar collagen within the interstitial space, can adversely influence myocardial stiffness and ultimately ventricular function. We have examined the relative importance of ventricular systolic and arterial pressures and the effector hormones of the renin-angiotensin--aldosterone system in mediating this reactive fibrous tissue response in the hypertensive left and normotensive right ventricles in various experimental models of arterial hypertension. To date, our findings implicate arterial hypertension, together with an elevation in plasma aldosterone, as being contributory to the fibrosis in renovascular hypertension that creates tissue heterogeneity in either ventricle and impaired diastolic function. The endocrine properties of aldosterone in this nonclassical mineralocorticoid target tissue, the myocardium, requires further investigation.

Increased variability of stimulus-driven cortical responses is associated with genetic variability in children with and without dyslexia (2018)

Individuals with dyslexia exhibit increased brainstem variability in response to sound. It is unknown as to whether increased variability extends to neocortical regions associated with audition and reading, extends to visual stimuli, and whether increased variability characterizes all children with dyslexia or, instead, a specific subset of children. We evaluated the consistency of stimulus-evoked neural responses in children with (N = 20) or without dyslexia (N = 12) as measured by magnetoencephalography (MEG). Approximately half of the children with dyslexia had significantly higher levels of variability in cortical responses to both auditory and visual stimuli in multiple nodes of the reading network. There was a significant and positive relationship between the number of risk alleles at rs6935076 in the dyslexia-susceptibility gene KIAA0319 and the degree of neural variability in primary auditory cortex across all participants. This gene has been linked with neural variability in rodents and in typical readers. These findings indicate that unstable representations of auditory and visual stimuli in auditory and other reading-related neocortical regions are present in a subset of children with dyslexia and support the link between the gene KIAA0319 and the auditory neural variability across children with or without dyslexia.
Multi-Base RTK Positioning Using Virtual Reference Stations (2000)

In the recent past, multiple approaches have been proposed
to implement the benefits of using multiple reference
stations for centimeter-level accurate GNSS positioning.
A very promising and practically approved variant is the
use of the Virtual Reference Station concept. Here, the
modeling of error sources and the information fusion of
all reference data are done centrally in a network
computation center. The user is provided with Virtual
Reference Station data acting like a normal local
reference station. No modification of the user GPS
receiver is required to use this approach opposing to other
multi-base algorithms. This includes no additional
requirements on the processing power of the user
equipment. Another key advantage is the use of externally
provided information like predicted ephemeris.
Virtual Reference Stations lead to substantial
improvements for real-time positioning by reducing
atmospheric, orbital and multipath errors resulting in a
performance for long baseline as experienced from short
baselines using only one reference station.
The paper presents the techniques necessary to process
the data from the different reference stations in the
network, to resolve the ambiguities inside the network
and to generate the error models needed for Virtual
Reference Station generation. This covers the main error
sources in satellite navigation: ionosphere, troposphere,
satellite orbit errors and multipath.
Fundamental limitations of ambiguity resolution in realtime,
even on a network with known reference station
coordinates, are presented. They impact the design and
layout of a reference station network for high-precision
applications.
Another paper in this publication “Long-Range RTK
Positioning Using Virtual Reference Stations” presents
practical user experiences from several operating Virtual
Reference Station networks, providing fast and reliable
initializations even in times of high solar activity with
typically less that 1 minute initialization time on 30 km
baselines, while standard reference station applications
can be limited to 10 km.
Computer-aided control systems course instruction (2003)

Teaching of classical control can be significantly enhanced by incorporation of weekly computer lab sessions, utilizing the MATLAB/sup /spl reg// Control Systems Toolbox, Symbolic Math Toolbox and SIMULINK/sup /spl reg//. The paper discusses a basic control course curriculum planning, focusing on the tradeoffs that result from allocating lecture time to computer lab hands-on activities. Some of the specific computer lab activities are highlighted.
Characterization of an ABCA‐like transporter involved in vesicular trafficking in the protozoan parasite <i>Trypanosoma cruzi</i> (2004)

Protozoan parasites are responsible of important healthy problems, among others malaria, leishmaniasis and trypanosomiasis. The present work reports the characterization of the first mammalian ATP-binding cassette transporter, subfamily A (ABCA)-like in Trypanosoma cruzi. TcABC1 is a single copy gene differentially expressed along the life cycle of the parasite, being absent in its infective form. TcABC1 localizes to the plasma membrane, flagellar pocket and intracellular vesicles. Functional studies of TcABC1 in transfected parasites suggest that the protein is implicated in intracellular trafficking, as determined by the analysis of endocytosis and exocytosis events. The accumulation of the endocytic markers FM4-64 and NBD-SM is increased in transfected parasites. Similarly, ectophosphatase and ectoATPase activities are increased in TcABC1 overproducers. Indeed, transmission electronic microscopy analysis showed a higher number of intracellular vesicles in TcABC1 transfectants. Taken together, these results suggest that the protein is involved in the endocytic and exocytic pathways of T. cruzi.
Development of Large Area rf Induction Plasmas for Cost Effective Diamond (1993)

Progress continues on the development of a large area rf induction plasma system. An early problem with a hole in the deposition pattern has been assigned to poor gas distribution. The injection port has been modified to eliminate the hole . 30 microns films on quartz substrates have been fabricated. Plasma modeling and gas modeling have been initiated. A downstream process gas monitor has been proven. A smaller scale system for evaluating rf power vs. rate data is under construction. And, a data acquisition and process control package has been identified and ordered from National Instruments. Diamond, Large-area, rf, Induction.
Evidence for Less Irritation to the Peritoneal Membrane in Rats Dialyzed with Solutions Low in Glucose Degradation Products (2004)

A new generation of PDF with physiologic pH and low GDP level produce less irritation to the peritoneal membrane and better preserve its structural integrity. This effect seems to be related predominantly to minimized GDP concentrations.

High-density one-device dynamic MOS memory cells (1983)

Performance of one-device cells for dynamic random-access memories is described in terms of signal, noise, speed, soft error and process complexity. From an examination of areal layout and cross-section, five kinds of cells used in commercially available 64 Kbit DRAMs are compared, placing stress on the concept of the folded-data and open-data lines. Somes new DRAM cell concepts, such as a vertically structured capacitor, are proposed on the basis of the paper. The future application limit of the one-device cell seems to exist in the optical lithography of the next generation DRAM of 1 Mbit and beyond, not in the device concept itself.
Governing Nigerian Urban Centres (2013)

Unprecedented rapid urbanization, coupled with ineffective service delivery, corruption and intensification of poverty among the urban population are major problems Nigerian governments at the Federal, State and Local levels have to overcome if the country is to make any headway in its development goals. The extent of rapid urbanization in the country can be viewed from the fact that the urban population currently stands at an estimated 43% of the total national population of 140 million people. In 1950, the percentage of total Nigerians living in the urban centres of more than 20,000 was less than15 per cent. The rapidity of urbanization in Nigeria, both in spatial and demographic terms, has not been met with an effective system of policy making with regards to urban planning. This has led to a rise in slums and ineffective service delivery systems in the cities.  A majority of Nigerians in the cities live in slums, without access to basic services such as housing, primary health care, pipe borne water etc. Service delivery has therefore become one of the most serious problems in the urban areas. The article argues that if these problems are to be overcome, a policy should be put in place to cart out a role for the Federal Government, reduce corruption through community driven checks and balances which will ensure effective citizen participation. Moreover, the local governments should have the skilled manpower to deal with the problems of urbanization Key Words : Rapid Urbanization, Urban Governance, Service Delivery, Corruption, Accountability
GLYCEMIC INDEX AND EXERCISE METABOLISM (1997)

KEY POINTS 1. The glycemic index (GI) of a food represents the magnitude of the increase in blood glucose that occurs after ingestion of the food. 2. GI tends to be lower for foods that have a high fructose content, exhibit high amylose/amylopectin ratios, are present in relatively large particles, are minimally processed, and are ingested along with fat and protein. 3. Consumption of lower GI foods 30-60 min prior to an endurance exercise bout tends to promote the following effects during exercise: • Minimizes the hypoglycemia that occurs at the start of exercise. • Increases the concentration of fatty acids in the blood. • Increases fat oxidation and reduces reliance on carbohydrate fuel. 4. The GI of a food consumed during exercise is probably less important than at other times because the insulin response to carbohydrate ingestion is suppressed during exercise. 5. Consumption of high GI foods soon after exercise will probably optimally promote the restoration of muscle glycogen. 6. Although manipulation of the GI of ingested foods may alter exercise metabolism, the effect of the GI on exercise performance is controversial and requires additional research.
Sequencing Reactions for ALF (EMBL) Automated DNA Sequencer (2003)

Automated fluorescent DNA sequencing (, , ) has turned into a subject of great interest during the last few years, and has successfully been applied to large-scale sequencing projects, like sequencing of the human HPRT gene locus (). Most actual genome sequencing efforts, such as sequencing the C. elegans genome, are performed on automated devices.
Layer stripping for time-harmonic Maxwell's equations with high frequency (1994)

The inverse boundary value problem for Maxwell's equations is considered. The objective is to estimate the electric permittivity and conductivity as well as the magnetic permeability within a body from stationary high-frequency field measurements on the boundary of the body. A layer-stripping algorithm for estimating the parameters in the body can be described as follows. First, the unknown parameters are estimated at the boundary of the body by applying highly oscillating field excitations. Then the surface data are propagated through the estimated surface layer by an invariant embedding equation. Repeating the process, one 'peels off' the body layer by layer. The aim of this article is to show that the necessary tools for the algorithm applied to Maxwell's equations exist. A propagation equation for the boundary data is derived and it is shown that measurements with high spatial variations give an estimate for the unknown material parameters at the boundary. Due to the energy dissipation, the method is expected to work near the boundary of the body.
The effect of pH modification during fermentation on the quality parameters of central African black teas (1980)

Abstract Adjusting the pH of fermenting tea from the physiological value to within the range 4.5–4.8 resulted in an increase in theaflavin content, a reduction in thearubigin levels, and an increase in the organoleptic evaluation of the product. Industrial‐scale acidification of commercial leaf was practicable and the market price realised on the London auction floors for treated teas was considerably higher than that for control consignments.
Morphological and Functional Rescue in RCS Rats after RPE Cell Line Transplantation at a Later Stage of Degeneration (2008)

RPE cell line transplants delivered later in the course of degeneration can preserve not only the photoreceptors and inner retinal lamination but also visual function in RCS rats. However, early intervention can achieve better rescue.
Immunohistochemical evidence of immune responses to tumor-associated antigens in lymph nodes of colon carcinoma patients (1991)

The authors investigated by immunohistochemical study the drainage of three tumor-associated antigens in unaffected regional lymph nodes of colon cancer patients. The study was conducted using monoclonal antibodies (MoAb) directed against different epitopes of the tumor-associated glycoprotein, TAG-72 (CC-49, CC-83, B72.3), of the carcinoembryonic antigen (CEA) (COL-4, COL-12), and of the colon-associated antigen, CAA (anti-CAA). The authors detected immunohistochemical reactions of MoAb CC-49 and anti-CAA with antigen-presenting cells (APC), such as peritumoral and sinus macrophages and lymphatic endothelial cells and with specific areas of germinal centers in lymph nodes draining 11 of 24 colorectal carcinomas studied. The corresponding primary tumors expressed the TAG-72 and CAA antigens. No immunostaining was detectable in lymph nodes using the anti-CEA MoAb, even when the primary tumors strongly expressed the specific epitopes. In germinal centers of regional lymph nodes, the immunostaining was often distributed at the periphery with a characteristic crescentic or circular pattern, which strongly suggested the exposure of the specific epitopes defined by MoAb CC-49 and anti-CAA on follicular dendritic cells. This would indicate that these epitopes are selectively recognized and presented to germinal center B-cells. This phenomenon may have clinical and diagnostic implications.
Synthesis and characterization of aromatic polyamides containing alkylphthalimido pendent groups (2002)

Abstract A series of polyisophthalamides containing pendent phthalimido groups and flexible side spacers were prepared from four novel diacids and three commercial aromatic diamines. These polyamides were prepared in high yields and with high molecular weights by direct polycondensation with triphenyl phosphite and pyridine as condensing agents. The weight‐average and number‐average molecular weights, measured by gel permeation chromatography, were 70,000–137,000 and 47,000–86,000 g/mol, respectively. The novel polyamides were amorphous and readily soluble and showed glass‐transition temperatures of 150–240 °C, as measured by differential scanning calorimetry. Thermogravimetric analysis showed that the 10% weight‐loss temperatures in nitrogen were 355–430 °C, a significant improvement in thermal stability having been observed with the increase in the side‐chain length. A theoretical quantum mechanical study was successfully carried out to explain these results. Flexible and tough films, cast from polymer solutions, showed tensile strengths of 50–125 MPa. © 2002 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 40: 3711–3724, 2002
Temperature shifts induce the selective loss of alveolar-macrophage plasma membrane components. (1982)

A shift in the incubation temperature of rabbit alveolar macrophages (0 degree C leads to 37 degrees C leads to 0 degree C) resulted in a 40-60% reduction in the ability of cells to bind alphamacroglobulin. 125I-trypsin complexes (alphaM. 125I-T). The reduction in binding activity did not reflect a disruption of cell integrity since the levels of intracellular components (lactate dehydrogenase, beta-N-acetyl-hexosaminidase) or other plasma membrane components (alkaline phosphodiesterase) were unaltered. Analysis of receptor-ligand interaction indicated that the temperature shift effected a decline in receptor number rather than an alteration in ligand-receptor affinity. Studies indicated that a temperature shift resulted in the loss of unoccupied receptors, and that ligand bound to receptors was not lost. However, after ligand internalization, receptors were removed by the temperature shift. The rate of receptor loss was maximal when cells were incubated at temperatures greater than 24 degrees C. Receptor loss was not prevented by treatment of cells with colchicine, cytochalasin B, or N-ethylamaleimide, but was prevented by treatment with the cross-linking agent paraformaldehyde. Data indicate that the reduction in alphaM. 125I-T binding activity resulted from shedding of receptors into the media since media obtained from temperature-shifted cells contained material that competed with cell-bound receptors for alphaM. 125I-T. Additionally, binding of alphaM. 125I-T was diminished on membrane fragments obtained from temperature-shifted cells. Incubation with Triton X-100, of cells whose receptors were occupied with alphaM. 125I-T, led to the extraction of 40% of cell-bound activity. However, no radioactivity was extracted from cells labeled with alphaM. 125I-T after a temperature shift. Measurement of ligand accumulation by control and temperature-shifted cells incubated at 20 degrees C indicated that control cells exhibited a subpopulation of receptors capable of binding ligand but only slowly internalizing it. This subpopulation was not present on temperature-shifted cells. These results indicate that surface receptors for alphamacroglobulin . protease complexes are heterogeneous and that the temperature shift resulted in the selective loss of membrane components.
