Recovery narratives: 'see how far i've come'

As the paradigm shift towards a recovery-oriented mental health system becomes more prominent, individuals with lived experience of mental illness will continue to write and speak their narratives of mental illness and recovery. This article discusses the social reality of people with mental illness: how they are stigmatized by the media and how competing narratives within the mental health system afflict people with this disability. It also discusses the empowering process of constructing a narrative that enables the narrator/speaker to find meaning in her/his experience while putting a realistic 'face' on mental illness and recovery for the general public. It further describes how telling a narrative to diverse audiences, including a college class of 'people in recovery' enhances the author's personal recovery by giving his life new meaning and purpose.
Epstein–Barr virus expression in plasma cell neoplasms and its association with plasmablastic morphologic features

Plasma cell neoplasms include plasma cell myeloma, plasmacytoma, primary amyloidosis, and light and heavy chain deposition diseases. Epstein–Barr virus (EBV) expression has rarely been reported to be associated with plasma cell neoplasms except for patients with a previous history of transplantation or severe immunodeficiency. In contrast, EBV expression has been reported in the majority of plasmablastic lymphoma, a subtype of diffuse large B cell lymphoma. We report three cases with a plasma cell neoplasm (two plasma cell myelomas and one case of plasmacytoma), where EBV infection was diffusely detected by in situ hybridization. All three patients were under the age of 40 years, and one of the three patients was an HIV-positive individual while the other two patients did not have any identifiable source for immunosuppression. All three cases showed multifocal plasmablastic features, which is concordant with the most recent reports about the possible association of EBV expression with plasmablastic morphologic features and increased proliferative activity.
Preparative reversed-phase liquid chromatography of proteins from rabbit skeletal troponin, a multi-protein complex.

A reversed-phase high-performance liquid chromatography protocol for purification of all proteins in a multi-protein (TnI, TnC, TnT, tropomyosin) complex from rabbit skeletal muscle has been developed, enabling efficient purification of sample amounts ranging from 43 mg of protein complex on a standard analytical column, to 1400 mg on a column of 21.2 mm I.D. and finally, to 5700 mg on a column of 50 mm I.D. Due to problems associated with scale-up procedures for these proteins (e.g. aggregation and/or solubility issues), an initial sample fractionation was devised whereby 50% of the TnC component was precipitated with acetonitrile prior to sample introduction on the RPLC column. By subsequently taking advantage of sample overload conditions to enhance the displacement effect between sample components, coupled with very slow gradient conditions (0.1% acetonitrile/min), we were able to achieve excellent protein separations at high yields of purified proteins.
Inadequacy of species-level designations for ecological studies of coastal migratory fishes

The species is not always appropriate as a unit of measure when used in quantitative ecological studies. Analyses of fish trophic relationships in coastal areas indicate that, in many instances, more substantial ecological differences exist among life stages of a given species than among similar trophic units of different species. The use of a species in quantitative ecological studies can lead to problems of interpretation concerning the relationships of coastal fishes to complex habitats. Use of the species as a convenient unit of measure substitutes a basically taxonomic entity for more relevant life-history stages in ecological determinations. Niche breadth of a given species can be so extensive that quantitative determinations of significant ecological processes are difficult to make. Migratory coastal fishes undergo diverse ontogenetic trophic transformations. Without adequate recognition of the complex ecological stages that characterize such fishes, the oversimplification that characterizes many ecological studies in coastal areas will continue. This simplification, and the attendant overgeneralization that follows, tends to add to the continuing problem of unverified models and the inability to identify causal relationships in estuarine and coastal systems. Quantitative ecological studies would benefit from an approach that includes the use of identifiable, ontological trophic entities.
Specificity of carbachol in the elicitation of drinking

Two studies were reported in which rats with hypothalamic cannulae were injected with carbachol. All animals exhibited drinking following injection. In the first study, this was demonstrated both prior to and following a series of test sessions, and in the second study, at the end only. During the test sessions themselves, only food was available. Animals displayed no tendency to increase their food intake upon carbachol administration during the 16 test sessions. This was contrasted with the ease with which such shifts have been demonstrated with electrical stimulation and suggests a specificity of function that can be detected with chemical but not electrical stimulation.
The Bidirectional Cavopulmonary Shunt for Hypoplastic Left Heart Syndrome

The use of the bidirectional cavopulmonary shunt has had a favorable effect on the outcome of surgery for hypoplastic left heart syndrome. In this chapter, the physiology, indications, and technical aspects are discussed, along with comments regarding postoperative management and outcome.
MEMS-based sensor arrays for military applications

Scientists and engineers at the Army Aviation Missile Command's (AMCOM) Research, Development and Engineering Center (RDEC) are cooperatively working with the Defense Advanced Research Projects Agency (DARPA), other Army agencies, and industry to provide technical solutions for the Army's transformation efforts into the 21st Century force. Advanced technologies are being exposed to achieve the performance and cost goals dictated by the emerging missions of the Transformed Army. It is well established that MEMS technology offers the potential solution to cost, size, and weight issues for the soldier, missile, gun, ground vehicles, and aircraft applications. MEMS sensor arrays are currently being investigated to meet system performance requirements and provide more robust mission capability. A Science and Technology Objective, Research and Development Project is underway at AMCOM/RDEC to develop controlled MEMS sensor arrays to provide for full military dynamic performance ranges using miniature sensor system. MEMS-based angular rate sensors are enhanced with vibration feedback form MEMS accelerometers for output signal stabilization in high-vibration environments. Multi-range MEMS-based accelerometers, cooperatively developed by Government and industry, are being multiplexed to provide dynamic range expansion. An array of integrated accelerometers is expected to increase the dynamic range by an order of magnitude. Future projections suggest that MEMS sensor array technology will be applicable to a broad range of military applications, which include environmental sensor suites for structural health monitoring and forward reconnaissance and surveillance; and optical and radio frequency phased arrays for fast beam steering.
TRANSPLANTATION POTENTIAL OF FRESH AND STORED HEMATOPOIETIC TISSUE AS ESTIMATED BY STANDARD IN VITRO TECHNIQUES

The ability of three in vitro systems to predict marrowrepopulating potential was tested and it was found that the data do not measure this potential. The results of dyeexclusion tests are greatly influenced by the suspension medium and the prior treatment of cells. They are widely used in estimating the viability of homogeneous suspensions of cells such as lymphocytes or tumor cells, but marrow is a suspension of heterogeneous cells. In tissue culture, it was noted that the sick-looking thawed cells return to a state of apparent good health and activity, but were not able to apply these observations to study of the repopulating unit. Early in short-term tissue culture the thawed cells appear damaged. It is anticipated that any in vitro test of viability applied shontly after thawing would be greatly affected by this apparent damage. Incorporation of labeled thymidine into DNA apparently reflects the number of cells in the phase of DNA synthesis, but there is no evidence that it reflects the number of viability of the cells responsible for repopulation.

The growth of ice parallel to the basal plane in supercooled water and supercooled metal fluoride solutions

Abstract The growth rates of ice dendrites in pure water and in 10 -2 molar aqueous solutions of LiF, NaF, KF, and AlF 3 have been measured for supercoolings ranging from 0.1 °C to 2.5 °C. In this range of supercoolings the ice crystals are dendritic and grow parallel to the basal plane. The experiments in pure water show that the radius of curvature of the tip decreases with increasing supercooling and that the growth rate varies periodically about the average growth rate. The experiments indicate that the enhancement of the growth rate of ice dendrites in supercooled aqueous metal fluoride solutions is due to the preferential orientation of the water molecules by the interface freezing potential.
Anthropomorphism, marketing relationships, and consumption worth in the Toy Story trilogy1

Abstract Who doesn't love a toy? Toys become our friends, our inspirations, and our creations. What is interesting about these significant relationships is that they are formed with rather ordinary commercial products. While this may seem natural enough, Pixar's Toy Story trilogy provides us a glimpse into the other side of this relationship, that is, from the perspective of the toys. Through a highly sophisticated use of anthropomorphism, the films reveal that these relationships are far from one-sided, value-based, identity-laden, symbolic manifestations. Instead, they encompass a mutually constituting, evolving, defining, and ever-changing process, in which we become our objects as much as our objects become us. As a result, it is important to look beyond the relative value of these objects in order to assess their overall worth.
A class of characteristic-value problems

This chapter discusses the existence of real numbers λ i such that a solution x (λ, t) on 0 x ″ + x F(x, λ, t) = 0 satisfies initial conditions. The chapter presents the theorem—Let D be the set {( x , λ, t) : — ∞ x x , hypothesis fourth is satisfied. Thus, this hypothesis has been viewed as describing or restraining the nonlinearity of equations. Thus, by lengthening the arguments to follow one may show that hypotheses third and fourth need only hold for large λ. Both of these hypotheses allow a pleasant physical interpretation if F in initial equation is viewed as a spring constant. For every non-negative integer n and every positive number p , there exists a λ pn and a solution x (λ pn , t, p) of Ρ having n zeros in (0, 1) and such that x′(λ pn , 0, p) = p . Furthermore, for each n there exists a particular p = p (n) such that the sequence of solutions {x (λ Ρ (n)n , t>p( n ))} admits a sequence {y n (t)} together with which it forms a complete biorthogonal system in L 2 ([0 1]).
Bone density in adolescents.

The loss of fluorescein, fluorescein glucuronide and fluorescein isothiocyanate dextran from the vitreous by the anterior and retinal pathways.

Abstract The pathways by which fluorescein (F), fluorescein glucuronide (FG) and fluorescein dextran (FD) leave the vitreous body of the rabbit were examined by measuring the concentration distribution of the injected fluorophores in sections of the frozen eyes. The contours of F, as already known, show that it leaves the vitreous predominantly across the retinal surface. Mathematical analysis of the concentration gradient leads to an average outward permeability coefficient of 1·4 × 10−3 cm min−1 for the retinal layers. The contours of FG and FD show that they leave predominantly by diffusion into the posterior chamber, encountering only a minor barrier at the anterior hyaloid membrane. The anterior contours indicate that there can be no substantial posteriorly directed fluid flow through the vitreous; if it occurs its velocity across the retinal surface must be less than 2 × 10−5 cm min−1. The contours of FD near the posterior pole of the retina suggest that such a flow may be taking place. Some time after the systemic administration of F, an analysis of the rate of loss of fluorescence from the vitreous body shows that this corresponds to the movement of FG out through the anterior chamber. Its value bears little relationship to the condition of the blood-vitreal barrier.
Application of the SWINT code to wing/body/tail geometries

Pressure and force calculations from the SWINT Euler code are presented and analyzed for a variety of configurations ranging from simple axisymmetric bodies to complex bodies with wings, tails, and inlets at speeds covering the supersonic Mach number range. The SWINT results are compared with both experimental data and with results from simpler computational methods to assess the increased accuracy from the Euler solution. It is shown that SWINT gives excellent results on axisymmetric bodies for attached flow; however, a better method of simulating the separation process on such bodies is needed for increased leeside accuracy. Good leeside accuracy, however, is found on a 3 to 1 elliptical body. It is shown that SWINT gives realistic downstream interference effects, resulting in good predictions of the overall aerodynamics for complex wing-body-tail geometries. The QUICK-geometry system has been coupled with SWINT code to provide a simplified geometry definition procedure for complex bodies. The QUICK method is shown to be a preferable alternative to the current method of inserting the body description directly into the code by FORTRAN statements.
Two phase natural convection adjacent to a vertical heated surface in a permeable medium

Abstract Two phase natural convection adjacent to a heated, vertical surface in a permeable medium is treated using boundary-layer approximations for conditions under which the vapor layer adjacent to the heated surface is thin. A similarity solution is obtained for the case in which density differences due to the phase change dominate those due to temperature variations in the liquid phase outside the vapor layer and for which the surface temperature, the temperature far from the surface, and the heat of vaporization do not vary with distance along the surface. The application of this solution to problems of practical interest using the approximation of local similarity is discussed.
HEMOLYSIS AND AUGMENTATION OF HEMOLYSIS BY NEUTRAL STEROIDS AND BILE ACIDS.

Abstract Thirty-five neutral steroids and bile acids have been studied for their ability to lyse rabbit erythrocytes. Hemolytic activity was found to be associated with the 5-β-H configuration. A few Δ-4,5 steroids were active, but 5-α-H compounds were inactive. Oxygenation at C-11 or the presence of an α-hydroxyl group at C-17 abolished activity. The hemolysis induced by neutral steroids was characterized by (1) sharp concentration dependence above a critical concentration; (2) marked loss of activity at 24° compared with 37°; (3) inhibition by serum; (4) prelytic loss of potassium; and (5) marked augmentation by inactive steroids, including the 3-β-OH and 5-α-H or Δ-4 compounds which inhibit bile acid-induced hemolysis. These results are compatible with the hypothesis that neutral steroids exert their pharmacologie effects, at least in part, through actions on the membranes of cells or their organelles.
Use of Scale Morphology for Discriminating Wild Stocks of Atlantic Striped Bass

Abstract We used scale morphology to discriminate wild Atlantic striped bass Morone saxatilis from the Hudson River, Chesapeake Bay, and the Roanoke River. Morphological features used were perimeter shape as described by Fourier analysis, rectangularity, width and spacing of the first 10 circuli, and patterns of partitioning of the scale interior. Performance of discriminant functions was evaluated by examining the percent correct classification of known-origin samples (precision) and the bias in resulting stock composition estimates (accuracy). Correct classification rates ranged from 57% to 84%, varying with the number of stocks and year-classes included. Lowest rates were for three stocks with multiple year-classes; highest rates were for single-year-class analysis of the most geographically distant stocks. Despite some poor classification rates, bias and variance in stock composition estimates were low in four of five discrimination problems, suggesting that corrections based on the classification mat...
Diffraction of Electrons as a Search for Polarization

Electrons accelerated by voltages from 80 kv to 225 kv passed through a thin homogeneous foil of polycrystalline gold and formed a diffraction pattern on a fluorescent screen. Through a hole in the screen, various rays of the diffracted beam were made in turn to fall on a second diffracting foil similar to the first. The second diffraction pattern was obtained on a photographic plate and examined for any asymmetry that might be caused by polarization of the electron beam. After certain asymmetries in the apparatus were corrected, no asymmetry was found in the diffraction pattern. By interposing a vane for a given fraction of the time of exposure over part of the plate, a partial calibration of the plate could be obtained directly. It was estimated that if there was any asymmetry at all, it was certainly not above 10 percent and probably not above 5. From this result and the observations of other workers at voltages from 100 kv down, it seems safe to conclude that diffraction is wholly, or largely, ineffective in polarizing electrons with energies at any rate below 225 kv. This conclusion may be at variance with those of Rupp and Rupp and Szilard on double scattering and on scattering and diffraction of an electron beam. The relation of these different experiments is discussed.
Nuclear degeneration and the association of endoplasmic reticulum with the nuclear envelope and microtubules in maturing sieve elements of Gossypium hirsutum.

The study deals with ultrastructure in the degeneration of nuclei in maturing sieve elements of Gossypium hirsutum and the related late changes in structure and distribution of endoplasmic reticulum (ER). When the nucleus is still intact, the ER cisternae form slacks, some of which become applied to the nuclear envelope. In some stacks, ER is combined with microtubules (MT) in an orderly arrangement. In immature cells, the MT—ER complexes were only found associated with the nuclear envelope. Eventually, the nuclear envelope becomes discontinuous and cytoplasmic ribosomes appear in the space previously occupied by the nucleoplasm. The MT—ER complexes remain associated with parts of the nuclear envelope and are displaced toward the wall. Some of the stacked ER and the MT—ER system remain near the cell wall. The ER can become associated with plastids and mirochondria.
Improving the Conversational Skills of a College Student with Peer-Mediated Behavioral Skills Training

We used a multiple baseline design across behaviors to evaluate peer-mediated behavioral skills training to improve a complex repertoire of conversational skills of an undergraduate student diagnosed with a learning disability NOS. Following treatment, we observed a decrease in interrupting and content specificity and an increase in questioning. Treatment effects maintained with naive peers during unstructured conversations and outcomes compared favorably with normative data on the conversational skills of three undergraduates without learning disabilities.
Parity of the order parameter in high-temperature superconductors with respect to a pi /2 rotation.

In order to establish the parity of the order parameter in the model based on the idea of a strong phonon-mediated long-range attraction, enhanced by the extended saddle-point singularities in the electron spectrum, plus a weak short-range repulsion, a comparison of critical temperatures and free energies of the even and odd solutions for the order parameter is performed. A criterion is established distinguishing the two options. It is shown, particularly, that superconductivity, induced by phonons, can, nevertheless, lead to an odd order parameter. On the other hand, contrary to the previous statements, this is the only possibility for the order parameter to change its sign within this model. The theory is influenced by the latest experimental results.
Mixing and Accretion in λ Bootis Stars

Strong evidence for deep mixing has been uncovered for slowly rotating F and A stars of the main sequence. As the accretion/diffusion model for the formation of λ Bootis stars is heavily dependent on mixing in superficial regions, such deep mixing may have important repercussions on our understanding of these stars. It is shown that deep mixing at a level similar to that of FmAm stars increases the amount of matter that needs to be accreted by the stars with respect to the standard models by some 3 orders of magnitude. It is also shown that significantly larger accretion rates have to be maintained, as high as 10-11 M☉ yr-1, to prevent meridional circulation from canceling the effect of accretion. The existence of old (≈1 Gyr) stars is not a likely outcome of the present models for accretion/diffusion with or without deep mixing. It is argued that λ Bootis stars are potentially very good diagnostics of mixing mechanisms in moderately fast rotators.
Does hunting threaten timber regeneration in selectively logged tropical forests

Avoiding the conversion of tropical production forests to non-forest land uses is a forestry and conservation priority, and is contingent on successful regeneration of commercially important species. The underlying ecological processes that facilitate regeneration, however, are poorly understood. Perhaps as a result, timber yields after regeneration can be lower than expected. Hunting is widespread in timber concessions, and may threaten regeneration by disrupting the various processes facilitated by wildlife. Vertebrate seed dispersers are often heavily hunted, resulting in reduced seed movement for many species and a shift in community composition to favor those plants dispersed by small animals and abiotic means. Timber species with large seeds and fleshy fruit are at particular risk for dispersal and recruitment failure. Hunting also alters granivore communities, resulting in increased predation on species favored by insects and small rodents, and changing the spatial template of seed predation, with detrimental effects on many timber species. Large vertebrate herbivores decline with hunting pressure, resulting in the modification of plant competitive interactions. This is disadvantageous to several traits that are common among timber trees, including relatively slow growth and high wood density. A lack of appreciation for – and management of – these interactions could threaten forest biodiversity, limit future timber production, and increase the likelihood of forest conversion for other land uses. In this review, I highlight the plant-animal interactions that could influence timber regeneration in tropical forests, as well as how these processes might be expected to change under hunting pressure. The review concludes with recommendations for management and future research priorities.

Ovarian cancer stem-like side-population cells are tumourigenic and chemoresistant.

Ovarian cancer is the most lethal gynaecological malignancy. Although ovarian cancer patients often respond initially to chemotherapy, they usually develop chemoresistance. We hypothesised that a small portion of ovarian cancer cells have stem-like cell properties that contribute to tumourigenesis and drug resistance. Flow cytometry and Hoechst 33342 efflux isolated side-population (SP) cells from ascites derived from ovarian cancer patients and from mice inoculated with human ovarian cancer cell lines. The SP cells were examined for stem cell markers OCT4, NANOG, STELLAR, and ABCG2/BCRP1 by immunocytochemistry and RT–PCR. The SP cells and non-SP cells were studied for tumourigenesis and chemoresistance in vitro and in vivo. The SP cells expressed ABCG2/BCRP1, OCT4, STELLAR, and NANOG, detected by immunocytochemistry and RT–PCR. ABCG2/BCRP1 expression was higher in SP than in non-SP cells. Xenogeneic mice inoculated with SP cells yielded more tumours than did mice inoculated with non-SP cells. In parallel, SP cell culture resulted in extensive cell proliferation, which was markedly more than in non-SP cells. SP cells resisted chemotherapy compared with non-SP cells, both in vivo and in vitro. Ovarian cancer SP cells are tumourigenic and chemoresistant. ABCG2/BCRP1 has an important role in chemoresistance, which has implications for new therapeutic approaches.
Explicit Finite Difference Methods for Heat Transfer Simulation and Thermal Process Design

A considerable difference between two explicit finite difference heat transfer simulation approaches was described. Time step restrictions, which are often the basis for criticism of explicit methods, were shown to be less severe when the surface was not considered to have thermal mass. Thermal process design combines heat transfer and reaction kinetics considerations. Accuracy of lethality estimates depends on time step size. Guidelines were developed for applying discrete time-temperature data to thermal process calculations. For time steps small enough to permit a linear temperature change approximation, it was shown that for increasing (decreasing) temperatures, a value within 50 to 60% (40 to 50%) of total temperature change should be used.
Photolithography of polytetrafluoroethylene for adhesion

Irradiation of polytetrafluoroethylene (PTFE) with Mg(Kα) X-rays is shown to protect the surface against the chemical etching steps used to prepare PTFE for adhesion. Preirradiated etched samples of PTFE have adhesion strengths to epoxies of less than 3% of that for nonirradiated etched samples. The major portion of this decrease in adhesion strength occurs for X-ray exposures of less than 10 min and failure in every case occurs in PTFE and not in the bonded transition region. XPS measurements (20 A sampling depth) show little difference in F content between irradiated and nonirradiated samples, but thermal desorption shows increasing short chain fluorocarbon desorption with irradiation time. These results are consistent with previous studies showing that irradiation produces free radicals that lead to branching and/or crosslinking, and a surface rich in low molecular weight fluorocarbons. The crosslinked surface is resistant to deep (10,000 A) chemical attack and rich in short chain fluorocarbons; both effects are expected to lead to weak adhesive bonding.
Patients with supraventricular tachycardia presenting with aborted sudden death : incidence, mechanism and long-term follow-up

A total of 13 (4.5%) of 290 patients with aborted sudden death had either documented (7; 54%) or strong presumptive evidence of supraventricular tachycardia that deteriorated into ventricular fibrillation. Six (46%) of the 13 had an accessory conduction pathway and either atrial fibrillation (5 patients) or paroxysmal atrioventricular (AV) reentrant tachycardia (1 patient) that deteriorated into ventricular fibrillation. Three patients with AV node reentrant tachycardia and four with atrial fibrillation and enhanced AV node conduction presented with supraventricular arrhythmias that deteriorated into ventricular fibrillation. Patients were treated with medical, surgical or catheter ablative procedures designed to prevent recurrences of supraventricular arrhythmias. Four patients received an implanted automatic defibrillator, but none had an appropriate device discharge. Over a follow-up period of 41.6 +/- 33.6 months, 12 patients are alive without symptomatic arrhythmias. One patient died because of severe chronic lung disease and heart failure. Supraventricular tachycardia was the cause of aborted sudden death in approximately 5% of patients referred for evaluation of sudden cardiac death. Treatment directed at prevention of supraventricular tachycardia was associated with an excellent prognosis. Current treatment techniques appear to obviate the need for automatic defibrillator therapy in these patients.
Solar variability of four sites across the state of Colorado

Solar Global Horizontal Irradiance (GHI) fluctuates on both short (seconds to hours) and long (days to months) timescales leading to variability of power produced by solar photovoltaic (PV) systems. Under a high PV penetration scenario, fluctuations on short time scales may require a supplementary spinning power source that can be ramped quickly, adding significant external cost to PV operation. In order to examine the smoothing effect of geographically distributed PV sites, GHI timeseries at 5 min resolution at four sites across the state of Colorado were analyzed. GHI at the four sites was found to be correlated due to synchronous changes in the solar zenith angle. However, coherence analysis showed that the sites became uncorrelated on time scales shorter than 3 h, resulting in smoother average output at short time scales. Likewise, extreme ramp rates were eliminated and the spread in ramp rate magnitude was significantly reduced when all four sites were averaged. Nevertheless, even for the averaged output, high frequency fluctuations in PV power output are relatively larger in magnitude than fluctuations expected from wind turbines. Our results allow estimation of the ancillary services required to operate distributed PV sites.
Easy, fast, and energy-efficient object detection on heterogeneous on-chip architectures

We optimize a visual object detection application (that uses Vision Video Library kernels) and show that OpenCL is a unified programming paradigm that can provide high performance when running on the Ivy Bridge heterogeneous on-chip architecture. We evaluate different mapping techniques and show that running each kernel where it fits the best and using software pipelining can provide 1.91 times higher performance and 42p better energy efficiency. We also show how to trade accuracy for energy at runtime. Overall, our application can perform accurate object detection at 40 frames per second (fps) in an energy-efficient manner.
A Capacitance Bridge for Determining the Ratio and Phase Angle of Potential Transformers

A capacitance bridge for the calibration of instrument potential transformers up to 300 kv is presented in this paper. This bridge provides measurements which are correct within 0.1 per cent on ratio and 3 minutes on phase angle. There are within the bridge arrangements for testing its accuracy as determined by the stability of its component arms. It is particularly desirable to have this means of self-testing if transformers are to be tested in a laboratory which does not have extensive standardizing facilities. Further advantages beyond accuracy for standardization purposes are flexibility and ease of operation for production testing, and low cost and small volume as compared to a high-voltage resistance potentiometer.
Big Five Personality Traits and Brand Evangelism

The objective of the study is to understand the relationships between each of the Big Five Personality Traits and the concept of brand evangelism. The hypotheses tested are whether brand evangelism relates to each of the Big 5 Personality Traits consisting of extraversion, openness, conscientiousness, neuroticism and agreeableness. A brand evangelist frequently exhibits a strong desire to influence consumption behavior. The research method of this study was based on the implementation of 528 self-administered questionnaires. The results include descriptive characteristics, Cronbach’s alphas, correlations and a multivariate regression model for testing the hypotheses. The results of the overall regression model show significance. Brand evangelism is significantly related to extraversion, openness and neuroticism. Future research is also discussed as understanding these personality traits and what drives individuals with these traits to become brand evangelists can strengthen a company’s success with its brand(s).
Proximity to Job Opportunities and African American Male Unemployment: A Test of the Spatial Mismatch Hypothesis in Indianapolis

Despite the lack of substantive research, the spatial mismatch hypothesis remains a pervasive explanation for the high rate of African American male unemployment. This research tests the hypothesis that census tract African American male unemployment rates are negatively related to the number of local job opportunities. This hypothesis is tested for Marion County, Indiana, the central county of the Indianapolis MSA. Weighted partial correlation coefficients of the logit of African American male census tract unemployment rates and indices of the availability of local job opportunities in manufacturing, services, and retail trade are statistically insignificant. The findings reject the spatial mismatch hypothesis in the specific context of Indianapolis in 1990.
Diamino telechelic polybutadienes for solventless styrene–butadiene–styrene (SBS) triblock copolymer formation

High molecular weight, high functionality diamino telechelic polybutadienes (TPBs) were synthesized by ring-opening metathesis polymerization (ROMP) of 1,5-cyclooctadiene (COD) in the presence of a chain transfer agent, 1,8-dicyano-4-octene, followed by lithium aluminum hydride reduction. Melt coupling of diamino TPB with anhydride-terminated polystyrene (PS-anh) resulted in the formation of styrene-butadiene-styrene (SBS) triblock copolymers; ca. 80% maximum conversion of PS-anh was achieved within 30 seconds. The results from SAXS, TEM, and rheological measurements of the coupling products confirmed the formation of SBS triblock copolymers having lamellar morphology. A fluororesent-labeled PS-anh was used to study the coupling kinetics by diluting the reactants by the addition of non-functional PS.
An Optimal Solution to the Distributed Data Retrieval Problem

We consider the problem of accessing large data files stored at multiple locations across a content distribution, peer-to-peer, or massive storage network. We assume that the data is stored in either original form, or encoded form at multiple network locations. Clients access the data through simultaneous downloads from several servers across the network. The central problem in this context is to find a set of disjoint paths of minimum total cost that connect the client with a set of servers such that the data stored at the servers is sufficient to decode the required file. We refer to this problem as the Distributed Data Retrieval (DDR) problem. We present an efficient polynomial-time solution for this problem that leverages the matroid intersection algorithm. Our experimental study shows the advantage of our solution over alternative approaches.
Fatal Disease in Nursing Puppies Associated with Minute Virus of Canines

Thirteen cases of a previously undescribed parvoviral infection affecting puppies ranging in age from 5 to 21 days is described. The cases were originally thought to represent an unusual pathologic manifestation of canine parvovirus-2 (CPV-2) infection. However, failure to confirm CPV-2 infection in any of the cases suggested a different parvovirus was involved. Minute virus of canines (MVC) was subsequently isolated from a case by using the Walter Reed Canine Cell Line, the only cell line which will support the growth of MVC. The pathologic and virologic findings for these 13 cases are described in this report.
Generation, transport, and preservation of the alkenone-based U 37 K′ sea surface temperature index in the water column and sediments of the Cariaco Basin (Venezuela)

[1] Alkenone fluxes in the water column of the Cariaco Basin ranged from 12 to 20 μg m−2 d−1 and were inversely related to upwelling strength. The U37K′ ratios of sinking particles varied from 0.78 to 0.96 and exhibited seasonal changes that were coherent with a 7°C variation in sea surface temperature (SST). The correlation between SST and U37K′ ratios closely overlapped with the calibration of Prahl et al. [1988]. Alkenone burial fluxes in Cariaco Basin sediments varied markedly over the past ∼6000 years, ranging from 0.2 to 5 μg m−2 d−1. The U37K′ ratios of surface sediments indicate SST was higher (26.3°C) during the last 50 years of deposition than in the previous 300 years (∼25°C), signaling an upwelling decrease in the latter part of the twentieth century. The lowest U37K′-derived temperatures (∼25°C) were measured in sediments deposited during the little ice age (LIA). These compositions, coupled with relatively low alkenone fluxes (≤2 μg m−2 d−1), are consistent with conditions of enhanced upwelling, decreased SST and reduced haptophyte production. The highest U37K′-derived SST estimates (over 26.5°C) were measured during the Medieval Warm Period (MWP) and suggest reduced upwelling at this time. Prior to the MWP, the alkenone record indicates temperatures of ∼26°C and burial fluxes of ∼2 μg m−2 d−1. These compositions indicate stronger upwelling conditions during the Holocene relative to the last 50 years and the MWP but annual SSTs above those estimated for the LIA.
Strong hydrogen bonding in chymotrypsin and other serine proteases

The hydrogen bond linking His57-Nδ1 and Asp102-Oδ1 in chymotrypsin (Cht) at low pH and in transition state analogue complexes of Cht with peptide trifluoromethylketones (peptide-TFKs) at pHs up to 12 has been assigned as a low barrier hydrogen bond (LBHB). The hydrogen bonds in these species of Cht display the physicochemical properties of LBHBs, as follows: 1) The proton NMR signals are far downfield, 18.1 ppm for Cht at low pH and 18.6–18.9 ppm for peptide-TFK complexes. 2) The D/H fractionation factors are low, 0.3–0.4 for the peptide-TFK complexes. 3) The deuterium and tritium isotope shifts (δD–δH, δT–δH) are negative. 4) The enthalpies of activation for solvent exchange (ΔHex) are high, 10–19 kcal mol−1. The LBHB is postulated to increase the base strength of His57 in the transition state for the nucleophilic addition of Ser195 to the peptide acyl group of a substrate. This property of His57 is displayed by His57 in the complexes of Cht with peptide-TFKs, in which its pKa lies between 10.6 and 12 depending on the structure of the peptide. These values are optimal for an acid/base catalyst that both abstracts a proton from Ser195 in the formation of the tetrahedral intermediate and donates a proton to the leaving N-terminal amino group in the decomposition of the tetrahedral intermediate. Strong hydrogen bonds in simple molecules can be studied in both aqueous and nonaqueous solutions, and the conditions for their existence are discussed. Copyright © 2004 John Wiley & Sons, Ltd.
Three-dimensional photon counting integral imaging using moving array lens technique

In this Letter, we present three-dimensional (3D) photon counting integral imaging using the moving array-lens technique (MALT) to improve the visualization of a reconstructed 3D scene. In 3D scene reconstruction of photon counting integral imaging, various techniques such as maximum likelihood estimation may be used. However, the visual quality depends on the number of scene photons or detector pixels activated by photons. We show that MALT may improve the viewing resolution of integral imaging for reconstructed 3D scene under photon-starved conditions.
The Relative Efficiency of Earthquakes and Explosions in Exciting Surface Waves and Body Waves

Summary Explosions are more efficient than earthquakes in exciting P waves, but earthquakes are more efficient than explosions in exciting Rayleigh waves. If an earthquake and an explosion have the same mb, then Ms for the earthquake should be about 0.5 larger than for the explosion. These results are derived by taking into account the moment tensor of a particular source and the partition of potential energy into compression and shear.
An Examination of the Factor Structure for the Youth Self Report on a Multiethnic Population

The Youth Self Report (YSR) is a popular and widely used instrument assessing adolescent emotional and behavioral functioning. The goals of the present study were to address some of the limitations of the YSR, to examine its factor structure and equivalence across four racial/ethnic groups, and to determine if another combination of items could accurately represent the constructs Achenbach sought to elucidate in a more parsimonious way. Exploratory and confirmatory factor analyses were utilized with random split-half samples to determine primary and secondary factors. Correlational analyses were then performed to determine the suitability of unit-weight factors as measures of the factors. And to examine the invariance of the short form YSR over ethnic groups, the covariance matrices were compared using structural equation modeling. Results revealed a seven factor scale that is shorter (66 vs. 119 items), is invariant acrossracial/ethnic groups, and has a simple structure. Implications and future direction...

Design methodology for a one-shot Reed-Solomon encoder and decoder

The design methodology for a high-performance and compact one-shot Reed-Solomon encoder/decoder realized as a combinational circuit is presented. Under a two-level optimization approach, a combination of new encoding/decoding algorithms enabling highly parallel, yet shared architecture, and logic optimization methods tuned for huge-scale Galois field arithmetic operations, improves the circuit size and speed significantly. The higher level optimization not only can be entirely independent of the gate level optimization, but also further augments the advantages in the gate level optimization. As a result a (40-34,32)RS encoders/decoder soft IP-core achieving 45 ns latency and >7 Gb/s peak throughput without pipelining is realized using <90 K cells under 0.35 um CMOS gate-array technology.
Elevated intraocular pressure and dysthyroid orbitopathy

The evaluation of ocular hypertension in patients with dysthyroid orbitopathy is complex. The etiology of ocular hypertension may be acute orbital congestion (which raises the orbital venous pressure) or a fibrosed rectus muscle which tethers the globe. The authors have found that the vast majority of patients with dysthyroid orbitopathy do not require treatment for elevated intraocular pressure without compromising optic nerve function. If, however, there is clear evidence of primary open angle glaucoma they institute conventional glaucoma treatment. The authors present illustrative case reports and a discussion of their approach to this group of patients.
Protein Inhibitor of Nitric Oxide Synthase (NOS) and the N-Methyl-d-Aspartate Receptor Are Expressed in the Rat and Mouse Penile Nerves and Colocalize with Penile Neuronal NOS

Nitrergic neurotransmission triggering penile erection is mediated by nitric oxide (NO) synthesized in the cavernosal nerves of the penis by penile neuronal NO synthase (PnNOS). In the central nervous system, nNOS is activated by the N-methyl-D-aspartate receptor (NMDAR) and, presumably, is inhibited by the protein inhibitor of NOS (PIN). The PnNOS and NMDAR are expressed in the penis, and PnNOS has been localized in penile nerves. Both proteins colocalize with PIN in the hypothalamus and the spinal cord involved in the control of erection. The present study aimed to elucidate the relationship between PnNOS, PIN, and NMDAR in the penis. It was found that in the rat, PIN was expressed in the pelvic ganglion and the cavernosal nerve, and penile PIN cDNA was cloned, sequenced, and expressed. Immunohistochemistry localized PIN to the cavernosal and dorsal nerve of the penis, whereas NMDAR was not detected in the latter. Dual-fluorescence labeling showed that PnNOS colocalized with PIN in both nerves but with NMDAR only in the cavernosal nerve. Aging did not affect the mRNA levels of PnNOS, nNOS, NMDAR, and PIN. Both PIN and NMDAR were detected in penile nerves of the wild-type and nNOS(-/-) mouse. The PIN protein did not inhibit or bind NOS in penile extracts, and in vivo, PIN cDNA reduced the erectile response to electrical field stimulation. In conclusion, PIN and NMDAR colocalize with PnNOS in penile nerves, but the functional significance of these protein interactions for penile erection remains to be elucidated.
Degradation of Centromeric Histone H3 Variant Cse4 Requires the Fpr3 Peptidyl-prolyl Cis–Trans Isomerase

The centromeric histone H3 variant Cse4 in Saccharomyces cerevisiae is polyubiquitylated and degraded in a proteasome-dependent manner. We report here that the proline isomerase Fpr3 regulates Cse4 proteolysis. Structural change in Cse4 by Fpr3 might be important for the interaction between Cse4 and the E3 ubiquitin ligase Psh1.
The SUMO ligase PIAS1 regulates UV-induced apoptosis by recruiting Daxx to SUMOylated foci

The small ubiquitin-like modifier (SUMO) ligase PIAS1 (Protein Inhibitor of Activated Stat-1) has been shown to play a role in cellular stress response by SUMOylating several proteins that are involved in DNA repair, apoptosis and transcription. In this paper, we show that PIAS1 regulates ultraviolet (UV)-induced apoptosis by recruiting Death-associated protein 6 (Daxx) to PIAS1-generated SUMO-foci. Cells that ectopically express PIAS1, but not other PIASes, show increased sensitivity to UV irradiation, suggesting that PIAS1 has a distinct function in UV-dependent apoptosis. Domain analysis of PIAS1 indicates that both PIAS1 SUMO-ligase activity and the specific localization of PIAS1 through its N-terminal and C-terminal domains are essential for UV-induced cell death. Daxx colocalizes with PIAS1-generated SUMOylated foci, and the reduction of Daxx using RNAi alleviates UV-induced apoptosis in PIAS1-expressing cells. PIAS1-mediated recruitment of Daxx and apoptosis following UV irradiation are dependent upon the Daxx C-terminal SUMO-interacting motif (SIM). Overall, our data suggest that the pro-apoptotic protein Daxx specifically interacts with one or more substrates SUMOylated by PIAS1 and this interaction leads to apoptosis following UV irradiation.
