Heart murmurs, valvular regurgitation and electrical disturbances in copper-deficient genetically hypertensive, hypertrophic cardiomyopathic rats.

Objective: Rats with a genetic tendency to develop hypertensive, hypertrophic cardiomyopathy were fed copper-deficient diets and their cardiac responses were investigated.Methods: Five male weanling rats of the Long-Evans and SHHF/Mcc-facp strains were randomly selected to receive diets containing either adequate quantities of copper (94.5 μmol Cu/kg diet) or reduced quantities of copper (<15.8 μmol Cu/kg diet) for 6 weeks, (n=5 within each group). Echocardiograms and electrocardiograms were recorded and analyzed at the end of the 6-week interval.Results: Electrocardiograms from copper deficient groups showed longer Q-T intervals and increased QRS amplitudes than controls. Both the copper deficient and control SHHF groups demonstrated significant QRS complex prolongation compared to Long-Evans rats. Echocardiography analysis showed significant increases in left ventricular area, free wall dimension, and myocardial cross-sectional areas in rats fed a copper deficient diet. The frequency of systolic cardiac...
The importance of different murine cell types in the immunopotentiation produced by amphotericin methyl ester.

Abstract Amphotericin R (AmB) or its methyl ester (AME) are potent stimulants of humoral and cell-mediated immunity in mice. When AME is injected simultaneously with antigen, it augments humoral immunity by expansion of the primary as well as the memory B cell pool. The most consistent and dramatic effect of amphotericin on humoral immunity is the enhancement of secondary IgG responses. This effect on the IgM-IgG switch mechanism depends on T cells and is reduced following thymectomy on adult mice. The route and timing of amphotericin administration also have dramatic quantitative, effects on immunopotentiation. Neither polyclonal B cell activation nor stimulation of antigen uptake in vitro by peritoneal macrophages was observed following intraperitoneal injection of AME. A tentative hypothesis is that antigen-stimulated T cells are important sites of the immunostimulant effects of AME on murine immune responses.
Fabricating a Gold Occlusal Platform on a Removable Partial Denture to Help Prevent Extrusion of Mandibular Incisors

A clinical procedure is presented in which a maxillary removable partial denture (RPD) replacing anterior teeth was fabricated with a cast gold anterior occlusal platform. This treatment is indicated to correct abrasion caused by extruded mandibular anterior teeth on the maxillary RPD. The advantages compared with prosthetic teeth supported by an acrylic resin base or metal-backed facings are discussed. This technique allows for development of optimal esthetics, strength, and durability, while preventing further extrusion and excessive wear of the teeth occluding against prosthesis.
Isotretinoin produces significant inhibition of monocyte and neutrophil chemotaxis in vivo in patients with cystic acne.

Abstract The effect of oral isotretinoin (13- cis -retinoic acid) on in vivo chemotactic responses was studied longitudinally in 7 patients with cystic acne. As measured in a microchamber chemotaxis assay, both monocyte and neutrophil chemotaxis were inhibited 98% ( p
Seismic Response Spectrum Analysis of the Single Vertical Centrifugal Pump

A dynamic model of the single vertical centrifugal pump was established to avoid seismic disadvantageous direction towards the direction of continually occurring earthquake during the designing and the installing. Finite element method was used to analyse the single vertical centrifugal pump and educe the first 20 natural frequencies and vibration shapes. Response spectrum method was adopted to do earthquake analysis. Response spectrum was inputted from different directions for getting different displacements and loads. According to the results, model’s direction of 45°~75° should be located at the direction of continually occurring earthquake to avoid the maximum vibration.
Determining the Composition of Liquid Droplets in a Gas of Different Composition

A novel probe is described that is capable of sampling liquid from droplets dispersed in a gas in such a way that the composition of the liquid is not changed during the sampling process. A unique feature of the probe design is the use of a wick of fibers that allows liquid to pass into the probe but excludes vapor. Another important feature is an ability to vary the flux of liquid droplets to the probe inlet over a substantial range. Such variation allows one to choose an operating condition that ensures the absence of composition distortion during the sampling process. The effectivness of the probe is demonstrated by experimental results obtained with dispersions of charged droplets now in common use as sources of ions in electrospray ionization mass spectrometry.
Photosensitized inactivation of infectious agents for sterilization of red blood cell concentrates and whole blood

More than 10 million units of human blood components are transfused annually in the United States. Although donor screening and testing have greatly lowered the risk of transmission of viral and protozoan infectious agents, additional sterilization procedures which also preserve blood component function would be of significant value. Use of visible-light-range photosensitizers for sterilization of red blood cells is currently being aggressively investigated in laboratory-scale optical-mechanical systems. Both the photochemical sterilization process and the optical-mechanical system must operate without introducing significant alteration in the properties of the red cells. With successful demonstration of the efficacy and safety of these sterilization techniques, implementation in the blood bank setting will require scale-up to optical-mechanical systems capable of handling approximately 50,000 units daily in 500 - 1,000 blood banks in the United States.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.

High speed aerodynamics of upper surface blowing aircraft configurations

An experimental investigation of the high speed aerodynamics of Upper Surface Blowing (USB) aircraft configurations has been conducted to accurately define the magnitude and causes of the powered configuration cruise drag. A highly instrumented wind tunnel model of a realistic USB configuration was used which permitted parametric variations in the number and spanwise location of the nacelles and was powered with two turbofan engine simulators. The tests conducted in the Ames 14 Foot Transonic Wind Tunnel examined 10 different configurations at Mach numbers from 0.5 to 0.775, fan nozzle pressure ratios from 1.1 to 2.1 and angles of attack from -4 to 6 degrees. Measured force data is presented which indicates the cruise drag penalty associated with each configuration and surface pressure contour plots are used to illustrate the underlying flowfield physics. It was found that all of the tested configurations suffered from a severe drag penalty which increased with freestream Mach number, power setting and angle of attack and was associated with the presence of strong shocks and regions of separated flow in the wing/nacelle junction regions.
MASS DIVERGENCES AND CALLAN--SYMANZIK EQUATIONS IN QUANTUM ELECTRODYNAMICS.

We discuss the connection between the theorems on mass divergences of unrenormalized (but regularized) vertex functions and the asymptotic Callan-Symanzik equations in quantum electrodynamics. To illustrate the point, we first use these theorems to give a rather simple derivation of the asymptotic Callan-Symanzik equation for the renormalized photon propagator and later generalize the analysis to the $2n+l$ vertex function. By a natural extension of the argument, one obtains nonasymptotic equations in which the inhomogeneous terms involve mass derivatives of the unrenormalized vertex functions multiplied by suitable products of the renormalization constants ${Z}_{2}$ and ${Z}_{3}$. As a by-product, one obtains partial differential equations for ${Z}_{2}$ and ${Z}_{3}$ regarded as functions of the masses. The method can be used when several internal masses are present in the problem, in either the conventional or the intermediate renormalization schemes.
The generation of capillary-gravity solitary waves by a surface pressure forcing

Abstract: A weakly nonlinear model is used to study capillary-gravity waves generated by a traveling localized surface pressure distribution. The weakly nonlinear model is a truncation of the potential flow equations in deep water, and includes cubic nonlinear terms. Numerically, solitary waves are shown to be generated by a near-monochromatic, subcritical forcing. The presence of these solitary waves is predicted using a forced nonlinear Schrodinger equation.
Chimaerins, novel non-protein kinase C phorbol ester receptors, associate with Tmp21-I (p23): evidence for a novel anchoring mechanism involving the chimaerin C1 domain.

The regulation and function of chimaerins, a family of "non-protein kinase C" (PKC) phorbol ester/diacylglycerol receptors with Rac-GAP activity, is largely unknown. In a search for chimaerin-interacting proteins, we isolated Tmp21-I (p23), a protein localized at the perinuclear Golgi area. Remarkably, phorbol esters translocate β2-chimaerin to the perinuclear region and promote its association with Tmp21-I in a PKC-independent manner. A deletional analysis revealed that the C1 domain in chimaerins is required for the interaction with Tmp21-I, thereby implying a novel function for this domain in protein-protein associations in addition to its role in lipid and phorbol ester binding. Our results support the emerging concept that multiple pathways transduce signaling by phorbol esters and revealed that, like PKC isozymes, chimaerins are subject to a positional regulation. In this setting, Tmp21-I serves as an anchoring protein that determines the intracellular localization of these novel phorbol ester receptors.
International capital movements: A synthesis of alternative models

Abstract The several alternative approches to international capital movements have not been compared theoretically. By showing that each represents a special case from a general simultaneous equation model, this note clarifies the theoretical relationships among the approaches, thus providing a convenient framework for their evaluation.
Intra-aneurysmal flow reductions in a thin film nitinol flow diverter

A novel hyper-elastic thin film nitinol (HE-TFN) covered stent has been developed to promote aneurysm occlusion by diminishing flow in the aneurysm. Laboratory aneurysm models were used to assess the flow changes produced by stents covered with different patterns of HE-TFN placed across the aneurysm neck in the parent vessel. The flow diverters were constructed by covering Wingspan stents (Boston Scientific) with different HE-TFNs (i.e., of 82% and 77% porosity) and deployed in both in vitro wide-neck and fusiform glass aneurysm models. In wide-neck aneurysms, the 82% porous HE-TFN stent reduced mean flow velocity in the middle of the sac by 86 ± 1%, while the 77% porous stent reduced the velocity by 93 ± 5% (n = 3). Local wall shear rates were also significantly reduced by about 98% in this model after device placement. Tests conducted on the fusiform aneurysm revealed smaller intra-aneurysmal flow velocity reduction by 48 ± 3% for the 82% porous stent and by 59 ± 7% for the 77% porous stent. The wall shear was reduced by approximately 50% by HE-TFN stents in fusiform models. These results suggest that HE-TFN covered stents have the potential to promote thrombosis in both wide-neck and fusiform aneurysm sacs.
Comparison of the electronic structure of amorphous and crystalline polytypes of Ge

Abstract We have calculated the density of states and the imaginary part of the dielectric constant as a function of energy for four polytypes of Ge using the EPM and the tight binding model developed by Weaire. The increasing complexity of the crystal structures indicates that short range disorder is able to account well for the optical properties and density of states of amorphous Ge. Furthermore, we predict the form of the optical properties and density of states for Ge III and Ge IV.
Numerical modelling of ocean circulation

Computational simulations of ocean circulation rely on the numerical solution of partial differential equations of fluid dynamics, as applied to a relatively thin layer of stratified fluid on a rotating globe. This paper describes some of the physical and mathematical properties of the solutions being sought, some of the issues that are encountered when the governing equations are solved numerically, and some of the numerical methods that are being used in this area.
Sequence-Specific, Nanomolar Peptide Binding via Cucurbit[8]uril-Induced Folding and Inclusion of Neighboring Side Chains

This paper describes the molecular recognition of the tripeptide Tyr-Leu-Ala by the synthetic receptor cucurbit[8]uril (Q8) in aqueous buffer with nanomolar affinity and exceptional specificity. This combination of characteristics, which also applies to antibodies, is desirable for applications in biochemistry and biotechnology but has eluded supramolecular chemists for decades. Building on prior knowledge that Q8 binds to peptides with N-terminal aromatic residues, a library screen of 105 peptides was designed to test the effects of residues adjacent to N-terminal Trp, Phe, or Tyr. The screen used tetramethylbenzobis(imidazolium) (MBBI) as a fluorescent indicator and resulted in the unexpected discovery that MBBI can serve not only as a turn-off sensor via the simultaneous inclusion of a Trp residue but also as a turn-on sensor via the competitive displacement of MBBI upon binding of Phe- or Tyr-terminated peptides. The unusual fluorescence response of the Tyr series prompted further investigation by 1H ...
Bow shocks around pulsars and neutron stars

Abstract Pulsar wind nebulae are now well-established as important probes both of neutron stars’ relativistic winds and of the surrounding interstellar medium. Amongst this diverse group of objects, pulsar bow shocks have long been regarded as an oddity, only seen around a handful of rapidly moving neutron stars. However, recent efforts at optical, radio and X-ray wavelengths have identified many new pulsar bow shocks, and these results have consequently motivated renewed theoretical efforts to model these systems. Here, I review the new results and ideas which have emerged on these spectacular systems, and explain how bow shocks and “Crab-like” nebulae now form a consistent picture within our understanding of pulsar winds.
Relation of embryo structure, node position, tillering and depth of planting to the effects of X-rays in barley

Abstract Biological, especially genetic, effects of X-rays in barley are influenced by embryo development, node position in M 1 plants, depth of planting and plant tillering. Bud or tillerinitial viability was determined with the vital stain, tetrazolium chloride. Both deeply planted and irradiated seeds exhibited reduced tillering from the bud in the axil of the coleoptile. Mutation rates (frequencies of chlorophyll-deficient M 2 seedlings) were calculated by the M 1 plant, M 1 spike, or M 2 seedling methods. Mutation rates were also determined by each method for apical spikes, primary and secondary axillary spikes, and each node position. These latter rates differed less from one another when scored by the M 1 spike or M 2 seedling methods than when scored by the M 1 plant method. The M 1 spike mutation curve approached closest to linearity for plants with all primary axillary and apical spikes present and with all duplicate mutants excluded. Reliable mutation rates can be calculated from the apical spike alone. Node position on the M 1 plants, with the exception of the fourth node, did not appear to affect mutation rates. Spikes above the fourth node and from secondary axillary tillers frequently had as many or more mutations than the primary axillary spikes. In fact, a higher mutation rate occurred in plants with higher numbers of tillers. Summarized mutation rates of the primaries at the upper nodes were higher than at the lower nodes. The converse was true for the secondaries which also had lower rates than the primaries. Fluctuations in rates were related to variations in embryo structure and to a decrease in the number of nodes (with tillers), spikes, and seedlings per plant. Therefore, the nearly linear mutation rates with increasing dose are probably related to high numbers of tillers which would permit mutant cells to be detected.
Hematologic effects of inactivating the Ras processing enzyme Rce1.

Posttranslational processing of Ras proteins has attracted considerable interest as a potential target for anticancer drug discovery. Rcel encodes an endoprotease that facilitates membrane targeting of Ras and other prenylated proteins by releasing the carboxyl-terminal 3 amino acids (ie, the -AAX of the CAAX motif). Homozygous Rce1 mutant embryos (Ree - / - ) die late in gestation. To characterize the role of Rcel in hematopoiesis, we performed adoptive transfers and investigated cells from the recipients. Ree1 - / - fetal liver cells rescued lethally irradiated recipients and manifested normal long-term repopulating potential in competitive repopulation assays. The recipients of Rce1 - / - cells developed modest elevations in mature myeloid cells (neutrophils + monocytes), but remained well. Bone marrow cells from mice that received transplants of Rce1 - / - activated extracellular signal-related kinase (ERK) normally in response to granulocyte-macrophage colony-stimulating factor. These data suggest that pharmacologic inhibitors of Rcel will have minimal effects on normal hematopoietic cells.
Deep learning vector quantization for acoustic information retrieval

We propose a novel deep learning vector quantization (DLVQ) algorithm based on deep neural networks (DNNs). Utilizing a strong representation power of this deep learning framework, with any vector quantization (VQ) method as an initializer, the proposed DLVQ technique is capable of learning a code-constrained codebook and thus improves over conventional VQ to be used in classification problems. Tested on an audio information retrieval task, the proposed DLVQ achieves a quite promising performance when it is initialized by the k-means VQ technique. A 10.5% relative gain in mean average precision (MAP) is obtained after fusing the k-means and DLVQ results together.
A Buddhist Christmas: The Buddha's Birthday Festival in Colonial Korea (1928-1945)

This article examines the dynamic aspects of the Buddha's Birthday festival as it was celebrated from 1928 to 1945 in colonial Korea. A joint Japanese and Korean Buddhist event sponsored by the state, it became the signature religious and state festival. Although much politicized, the festival was also a culmination of Buddhist efforts in Asia to respond to modernity, nationalism, colonialism, and Christian missions. Paralleling the reinvention of Christmas in the modern period, Buddhists reconfigured the Buddha's birthday as a symbol of their religious identity and power. The Buddha's Birthday festival should be understood in the context of increasing contact and exchange among Buddhists in the East and the West. The festival's prominence was the result of complex negotiation and collaboration between Korean and Japanese Buddhists who both hoped the festival would advance their overlapping visions of Buddhism. The festival was not so much an imposition of the colonizer on a native culture as it was a dynamic, creative feature of modern Korean Buddhism in the colonial context.
Adsorption of Volatiles from Roasted Tobacco on Activated Carbon and Desorptive Recovery by Ether Extraction

In order to recover the volatiles which can be used as cigarette flavor ingredients from tobacco-roasting treatment, adsorption on activated carbon and desorption by ether extraction were studied. Adsorption efficiencies were varied by physical properties of the activated carbons, i.e., raw material, specific surface area, acetone adsorption capacity, and micro pore size distribution. The affinities of volatile components for activated carbon are discussed with their adsorption efficiencies. Most of the volatiles adsorbed on activated carbon were recovered by diethyl ether extraction. Especially, thermal degradation products from sugar analogues were recovered in a good yield.
Seasonal physical–chemical structure and acoustic Doppler current profiler flow patterns over multiple years in a shallow, stratified estuary, with implications for lateral variability

Abstract The overall goal of this study was to strengthen understanding of the hydrographic structure in shallow estuaries as influenced by seasonal and depth-dependent variability, and by variability from extreme meteorological events. The mesohaline Neuse Estuary, North Carolina, U.S.A., which was the focus, receives surface inputs from upriver and tributary freshwater sources and bottom inputs from downriver high-salinity sound water sources, resulting in varying degrees of stratification. To assess depth-dependent, estuary-wide changes in salinity, a multiple time series was created using data from four discrete depths (surface and 1, 2, and 3 m ±0.25 m ). The database was developed from weekly to biweekly sampling of the entire water column, and included side-channel as well as mid-channel data. We characterized seasonal differences in halocline depth affecting the hydrographic structure of the mesohaline estuary and site-specific variation in nutrient concentrations, based on a comprehensive eight-year physical/chemical database. The first two years of the record showed an expected seasonal signal and included events that impacted the surface layer from freshwater inputs. Remaining years had greater variability over seasons and depths, with freshening events that affected all depths. Halocline depth was compared at specific locations, and a “snapshot” view was provided of the relative depth of these water masses within the estuary by season. We also examined flow patterns at the same cross-estuary sites over a three-year period, using a boat-mounted acoustic Doppler current profiler (ADCP) with bottom-tracking capability. Composite visualizations constructed with single-transect ADCP data revealed a classical estuarine circulation pattern of outflow at the surface/southern shore and inflow at the bottom/northern shore. Although this pattern deviated under extreme climatological events and was sometimes variable, the estuary generally exhibited a high probability of direction of flow. Wind fields, hurricanes, and small-scale, high-precipitation events represented significant forcing variables.
Test of a Model of Psychosocial Resources, Stress, and Health Among Undereducated Adults

The purpose of this study was to test a model drawn from the Modeling and Role- Modeling theory depicting relationships among psychosocial resources, perceived stress, and health for undereducated adults. A purposive sample of 171 adults enrolled at an urban adult ed- ucation center completed several self-report measures: Modified Erikson Psychological Stage Inventory, Basic Need Satisfaction Inventory, Perceived Stress, and Positive Health Index. Based on a structural equation modeling analysis, psychosocial development and basic need satisfac- tion had significant direct effects on health, with the expected positive signs. Psychosocial de- velopment had the strongest direct effect on health and also had a strong direct effect on basic need satisfaction and an indirect effect on health. Support for the hypothesized model has im- portant implications for nursing and other community-based care provider interventions regard- ing health, including strengthening psychosocial resources. © 2000 John Wiley & Sons, Inc.

CHARACTERIZATION OF FLUX-GROWN TRACE-ELEMENT-DOPED TITANITE USING THE HIGH-MASS-RESOLUTION ION MICROPROBE (SHRIMP–RG)

Crystals of titanite can be readily grown under ambient pressure from a mixture of CaO, TiO 2 and SiO 2 in the presence of molten sodium tetraborate. The crystals produced are euhedral and prismatic, lustrous and transparent, and up to 5 mm in length. Titanite obtained by this method contains approximately 4300 ppm Na and 220 ppm B contributed from the flux. In addition to dopant-free material, titanite containing trace alkali and alkaline earth metals (K, Sr, Ba), transition metals (Sc, Cr, Ni, Y, Zr, Nb, Hf and Ta), rare-earth elements (REE), actinides (Th, U) and p-block elements (F, S, Cl, Ge, Sn and Pb) have been prepared using the same procedure. Back-scattered electron (BSE) imaging accompanied by ion-microprobe (SHRIMP–RG) analysis confirms significant incorporation of selected trace-elements at structural sites. Regardless of some zonation, the large size of the crystals and broad regions of chemical homogeneity make these crystals useful as experimental starting material, and as matrix-matched trace-element standards for a variety of microbeam analytical techniques where amorphous titanite glass, heterogeneous natural titanite or a non-titanite standard may be less than satisfactory. Trace-element-doped synthetic crystals can also provide a convenient proxy for a better understanding of trace-element incorporation in natural titanite. Comparisons with igneous, authigenic and high-temperature metasomatic titanite are examined. The use of high-mass-resolution SIMS also demonstrates the analytical challenges inherent to any in situ mass-spectrometry-based analysis of titanite, owing to the production of difficult-to-resolve molecular interferences. These interferences are dominated by Ca–Ca, Ca–Ti and Ti–Ti dimers that are significant in the mass range of 80–100, affecting all isotopes of Sr and Zr, as well as 89 Y and 93 Nb. Methods do exist for the evaluation of interferences by these dimers and of polyatomic interferences on the LREE.
OASIS: a data and software distribution service for Open Science Grid

The Open Science Grid encourages the concept of software portability: a user's scientific application should be able to run at as many sites as possible. It is necessary to provide a mechanism for OSG Virtual Organizations to install software at sites. Since its initial release, the OSG Compute Element has provided an application software installation directory to Virtual Organizations, where they can create their own sub-directory, install software into that sub-directory, and have the directory shared on the worker nodes at that site. The current model has shortcomings with regard to permissions, policies, versioning, and the lack of a unified, collective procedure or toolset for deploying software across all sites. Therefore, a new mechanism for data and software distributing is desirable. The architecture for the OSG Application Software Installation Service (OASIS) is a server-client model: the software and data are installed only once in a single place, and are automatically distributed to all client sites simultaneously. Central file distribution offers other advantages, including server-side authentication and authorization, activity records, quota management, data validation and inspection, and well-defined versioning and deletion policies. The architecture, as well as a complete analysis of the current implementation, will be described in this paper.
Changes in the readily releasable pool of transmitter and in efficacy of release induced by high-frequency firing at Aplysia sensorimotor synapses in culture.

Scientometrics of anesthetic drugs and their techniques of administration, 1984–2013

The aim of this study was to assess progress in the field of anesthetic drugs over the past 30 years using scientometric indices: popularity indices (general and specific), representing the proportion of articles on a drug relative to all articles in the field of anesthetics (general index) or the subfield of a specific class of anesthetics (specific index); index of change, representing the degree of growth in publications on a topic from one period to the next; index of expectations, representing the ratio of the number of articles on a topic in the top 20 journals relative to the number of articles in all (>5,000) biomedical journals covered by PubMed; and index of ultimate success, representing a publication outcome when a new drug takes the place of a common drug previously used for the same purpose. Publications on 58 topics were assessed during six 5-year periods from 1984 to 2013. Our analysis showed that during 2009–2013, out of seven anesthetics with a high general popularity index (≥2.0), only two were introduced after 1980, ie, the inhaled anesthetic sevoflurane and the local anesthetic ropivacaine; however, only sevoflurane had a high index of expectations (12.1). Among anesthetic adjuncts, in 2009–2013, only one agent, sugammadex, had both an extremely high index of change (>100) and a high index of expectations (25.0), reflecting the novelty of its mechanism of action. The index of ultimate success was positive with three anesthetics, ie, lidocaine, isoflurane, and propofol, all of which were introduced much longer than 30 years ago. For the past 30 years, there were no new anesthetics that have produced changes in scientometric indices indicating real progress.
Good Muslims and "Bad Muslims," "Good" Women and Feminists: Negotiating Identities in Northern Cyprus (Or, the Condom Story)

This article examines the intersection of a "good/bad Muslim" identity with national, cultural, and gender categories in northern Cyprus. It analyzes the cultural and historical articulation of a modern, Western "bad Muslim" identity, and describes "the condom story," an event where some Turkish Cypriot women attempted to transgress the social boundaries around gender roles. It is argued that the complex negotiations over a national identity (Cypriot and/or Turkish), a modern identity (Eastern and/or Western), and a religious identity (Muslim and/or secular) result in contradictory messages about gender and sexuality for Turkish Cypriot women. This examination of identity negotiations-principally a bad Muslim identity, and of women's various attempts to subvert societal pressures-ultimately reveals some of the cultural controls over women's gender identity, particularly their sexuality, in Turkish Cypriot society.
Patterns and issues in multiaxial psychiatric diagnosis.

The multiaxial diagnostic model, consisting in the systematic formulation of a patient's condition according to separate clinical variables or aspects, is receiving increasing attention in several parts of the world. This innovative model promises to improve diagnostic reliability and validity and involves many methodological challenges. This paper reviews patterns and issues in the conceptualization of axial content, number and organization of axes, dimensional versus categorical scaling, and evaluation and further development of multiaxial systems.
AMPHOTERIC BEHAVIOR OF COMPLEX SYSTEMS : IV. NOTE ON THE ISOELECTRIC POINT AND IONIZATION CONSTANTS OF SULFANILIC ACID

From the solubility minimum the value of the basic ionization constant of sulfanilic acid is shown to lie probably between the values 1.7 x 10^–15 and 3.2 x 10^–15. From solubility measurements the value of this same constant is shown to lie probably between 2.0 and 2.2 x 10^–15, and the isoelectric point of sulfanilic acid is thus at a cH of 0.056 or a pH of 1.25. From conductivity ratios the acid ionization constant of sulfanilic acid is shown to be 7.05 x 10^–4 at room temperature (21°C.). Calculations are made, from data published in preceding papers, of the ionization constants of glycine, Ka being 2.3 x 10^–10, and Kb being 2.2 x 10^–12.
Assessment of a method used to time adjust past storm losses

A widely used method for adjusting past annual storm losses to present day values, needed to address the ever-changing socio-economic conditions, was assessed. The property insurance industry developed a comprehensive method for adjusting losses in past years to current year loss values. Characteristics of hurricanes occurring 50+ years ago and those in the recent years were examined to find similar early and recent pairs of storms for a comparative evaluation of their property losses. One pair found was Hurricanes Hazel (1954) and Hugo (1989), and another pair with similar features was Hurricanes Carol (1954) and Bob (1991). The insurance-based adjusted property loss values for these two pairs of storms were compared to determine if the early year values were comparable to the recent year values. The adjusted losses of the two pairs of hurricanes were found to have small differences of 7.8% and 8.1%, and these differences were due to somewhat different storm paths and slightly higher wind speeds in the two storms having higher losses. The adjustment method appears to adequately capture time differences in storm losses due to changes in population, wealth, inflation, structural density, and insurance coverage.
The relationship between early elementary teachers’ instructional practices and theoretical orientations and students’ growth in writing

We investigated the relationship between 28 teachers’ theoretical orientations to writing instruction and self-reported instructional practices and student writing performance. First-, second-, and third-grade teachers completed the Teacher Writing Orientation Scale developed by Graham, Harris, MacArthur, and Fink (2002) and reported the frequency of common instructional practices in writing. Student writing samples included a curriculum-based measurement writing assessment administered three times across the spring of a single school year and a subtest of a norm-referenced writing assessment. The correlational relationships between teachers’ theoretical orientations and their instructional practices varied by grade level. Multilevel models indicated that the relationships between teachers’ orientations towards writing instruction and student outcomes varied depending on the writing outcome and whether the model was predicting writing achievement or growth. These findings point to the need for additional research that could help to develop a better understanding of the ways teachers’ theoretical orientations, instructional practices, and student outcomes are related.
Terrain tracking based on optimal aim strategies

This short communication discusses two recently proposed terrain-tracking schemes, reformulates both schemes as special cases of a previously proposed optimal aim strategy, outlines a more precise and explicit continuous-time control law based on a fixed-point neural network, describes a more rapid and effective discrete-time control law based on a fixed-point iteration process, and derives criteria for matching reference models to the dynamical characteristics of individual systems.
Influence of preparation features on retention and resistance. Part I: MOD onlays

Four variations of an MOD onlay preparation were studied for retention and resistance. Boxes were more effective than an isthmus in increasing retention value. The combination of boxes and isthmus showed the highest retention. The combination of boxes and isthmus also exhibited the highest resistance. There was no difference in resistance between boxes and the isthmus.
INSIGHT: Internet-sensor integration for habitat monitoring

The design goals for our system, INSIGHT: Internet-sensor integration for habitat monitoring, are extended deployment lifetime, remote querying and configuration, ease of deployment, and reliability. We present results from our deployment of INSIGHT in a greenhouse.
Relative contributions of animal and muscle effects to variation in beef lean color stability

Muscles from beef carcasses (n = 100) were selected from a commercial processor and aged for 14 d. Longissimus lumborum (LL), semimembrano- sus (SM), biceps femoris (BF), gluteus medius (GM), triceps brachii (TB), rectus femoris, vastus lateralis, adductor, semitendinosus, infraspinatus, teres major, biceps femoris ischiatic head, biceps femoris sirloin cap, and gracillus steaks were placed in display for 9 d. Instrumental color variables (lightness (L*), redness (a*), yellowness (b*), hue angle, chroma, and overall color change from d 0 (∆E)) were determined on d 0, 1, 3, 6, and 9 of display. Muscle pH and myoglobin content were determined for LL, SM, BF, GM, and TB. Muscles differed (P 0.05) pH of BF or TB. Muscle effects generally explained more variation in a*, b*, hue angle, chroma, and ∆E than animal effects. However, the relative importance of animal effects increased as display continued. These data indicate that animal effects were consistent across muscles, though muscle effects had greater contribu- tion to color stability variation. Furthermore, strong relationships between LL color stability and the stabil- ity of other muscles indicate that strategies developed to manage animal variation in LL color stability would beneficially affect the entire carcass.
The tetrode power transistor

Power transistor circuits are characterized by the fact that the collector current must swing over a wide range of values during any complete cycle of operation. One disadvantage of present-day alloyed junction power transistors is that the current gain decreases with increasing collector current. This causes distortion in linear applications and makes temperature stabilization in switching circuits more difficult. Power transistors having emitter areas large enough to handle currents in the amperes range can be made as tetrodes by use of an annular ring geometry. Experimental results show that the gain characteristics can be altered by applying a bias voltage or a portion of the signal voltage transversely across the base. The gain characteristic can be made flatter for improved fidelity in audio applications, or even reversed to give increasing gain with collector current for certain switching applications. Practical circuitry utilizing the improved gain characteristics of power tetrodes has been developed, and the annular geometry permits the fabrication of tetrodes using conventional alloying techniques.
A model-driven performance analysis framework for distributed, performance-sensitive software systems

Large-scale, distributed, performance-sensitive software (DPSS) systems from the basis of mission- and often safety-critical applications. DPSS systems comprise of many independent artifacts, such as network/bus interconnects, many coordinated local and remote endsystems, and multiple layers of software. DPSS systems demand multiple, simultaneous predictable performance requirements such as end-to-end latencies, throughput, reliability and security, while also requiring the ability to control and adapt operating characteristics for applications with respect to such features as time, quantity of information, and quality of service (QoS) properties including predictability, controllability, and adaptability of operating characteristics for applications with respect to such features as time, quantity of information, accuracy, confidence and synchronization. All these issues become highly volatile in large-scale DPSS systems due to the dynamic interplay of the many interconnected parts that are often constructed from smaller parts.
Characteristics of an indirect-methanol fuel cell system

This paper discusses the various system interactions that can affect the efficiency and dynamic performance of an indirect methanol fuel cell system. The characterization of the load following IMFC system is done using the simulation model developed by the Fuel Cell Vehicle Modeling Program at the University of California-Davis. The first part of the paper briefly describes the components within the UCD-IMFC system model. The second part of the paper gives a qualitative look at the system interactions and their impact on the efficiency and dynamics of the system. There are two primary interactions within the IMFC system that are of interest. These two interactions are the fuel processor/stack interaction and the air supply/stack interaction. With respect to the fuel processor/stack anode interaction, we find a trade-off between going to a higher anode hydrogen utilization to maximize efficiency and going to a lower utilization to avoid starving the stack of hydrogen during heavy dynamic loads on the system. On the air supply/stack cathode interaction, we find that dynamics are not as much of an issue and the best operating method is one where the net power output of the stack/compressor combined is greatest for a given partial pressure of oxygen. This gives the highest efficiency for a given cathode/air supply combination. Finally, when considering the water and thermal management (WTM) of the system, we look at methods to reduce the total parasitic load on the satisfying the thermal requirements and maintaining water self-sufficiency.
Specificity of Projections from Wide-Field and Local Motion-Processing Regions within the Middle Temporal Visual Area of the Owl Monkey

The middle temporal visual area (MT) of the owl monkey is anatomically organized with respect to both preferred direction of motion and different types of center–surround interaction. The latter organization consists of clusters of neurons whose receptive fields have antagonistic surrounds that render them unresponsive to wide-field motion (local motion columns) interdigitated with groups of neurons whose receptive fields have additive surrounds and thus respond best to wide-field motion (wide-field motion columns). To learn whether the information in these regions remained segregated further along the visual pathways, we made injections of retrograde tracers into two visual areas to which MT projects [the medial superior temporal area (MST) and fundus of the superior temporal sulcus (FST)] and then labeled the wide-field and local organization using 2-deoxyglucose. In complementary experiments, we injected anterograde tracers into regions of MT that we had mapped using microelectrode recordings. Injections into both dorsal FST and ventral MST labeled clusters of cell bodies in MT that were concentrated within wide-field motion columns, whereas injections into dorsal MST labeled neurons predominantly within local motion columns. Results from the anterograde tracer experiments corroborated these findings. The high degree of specificity in the connections reinforces a model of functional organization for wide-field versus local motion processing within MT. Our data support the previously reported division of FST into separate dorsal and ventral areas, and they also suggest that MST of the owl monkey is, like MST of the macaque, functionally organized with respect to local versus wide-field motion processing.
A Distributed Multi-agent Model for Value Nets

In this paper, we discuss an agent based solution strategy to the new customer centric economy created by the Internet. This solution strategy includes changing the current supply chain model into a value net model that is driven by the customer and coordinated by a complex multi-agent network. To coordinate all activity within the multi-agent value net a new agent based communication language based on the Extensible Markup Language (XML) is proposed.
An Integrated Ultra-Wideband Timed Array Receiver in 0.13 $\mu{\hbox{m}}$ CMOS Using a Path-Sharing True Time Delay Architecture

A fully integrated CMOS ultra-wideband 4-channel timed array receiver for high-resolution imaging application is presented. A path-sharing true time delay architecture is implemented to reduce the chip area for integrated circuits. The true time delay resolution is 15 ps and the maximum delay is 225 ps. The receiver provides 11 scan angles with almost 9 degrees of spatial resolution for an antenna spacing of 3 cm. The design bandwidth is from 1 to 15 GHz corresponding to less than 1 cm depth resolution in free space. The chip is implemented in 0.13 mum CMOS with eight metal layers, and the chip size is 3.1 mm by 3.2 mm. Measurement results for the standalone CMOS chip as well as the integrated planar antenna array and the CMOS chip are reported.
Nonextensive cutoff distributions of postural sway for the old and the young

We examine postural sway data using concepts of nonextensive thermostatistics. We show that nonextensive thermostatistical cutoff distributions fit approximately empirically observed distributions of postural sway data. We show that the index of nonextensivity of these cutoff distributions is larger for elderly subjects than for younger subjects. A preliminary interpretation of the nonextensivity parameter as a measure for explorative versus conservative behavior is given.
From Equilibrium to Transport Properties of Strongly Correlated Fermi Liquids

We summarize recent results regarding the equilibrium and non-equilibrium behavior of cold dilute atomic gases in the limit in which the two body scattering length a goes to infinity. In this limit the system is described by a Galilean invariant (non-relativistic) conformal field theory. We discuss the low energy effective lagrangian appropriate to the limit a->infinity, and compute low energy coefficients using an epsilon-expansion. We also show how to combine the effective lagrangian with kinetic theory in order to compute the shear viscosity, and compare the kinetic theory predictions to experimental results extracted from the damping of collective modes in trapped Fermi gases.
Brain Adrenergic Neurons

Neurons containing phenylethanolamine-N-methyltransferase and the other enzymes required for epinephrine synthesis exist in three clusters in the mammalian brain stem. These ‘adrenergic neurons’ appear to be functionally involved in regulation of the sympathetic nervous system and the integration of autonomic, behavioral, and endocrine responses. While typically thought of as adrenergic neurons, evidence exists to question whether these neurons utilize epinephrine as a signaling molecule.

Database monte carlo for simulation on demand

In the simulation-on-demand paradigm, we invest computational effort by running a simulation experiment before a question is asked, and then we quickly provide an answer by making use of the results of the earlier simulation experiment. This can be done by building a metamodel, but standard metamodeling methods used in stochastic simulation have the disadvantage that they require validation. We show how to use Database Monte Carlo with control variates to provide simulation-on-demand without metamodel validation.
