Evaluation of myocardial function and perfusion in ischemic heart disease

Ischemic heart disease is the most frequently encountered cardiac disease. Magnetic resonance imaging (MRI) can be used to investigate several facets of this disease. A number of studies over the past several years have shown the capability of cine MRI for quantifying regional myocardial function and for identifying abnormalities of regional myocardial wall thickening in the basal or vasodilated states due to ischemia. Contrast-enhanced inversion recovery fast gradient echo and echo-planar imaging have been applied for monitoring the first passage of contrast media through the myocardium. This technique has depicted regional perfusion deficits in the basal state or in the vasodilated states induced by vasodilators. Recent studies have also disclosed the feasibility of using MR techniques for displaying the morphology of the major coronary arteries and for measuring blood flow velocity in the coronary arteries and coronary bypass grafts. Thus, MRI has the capability for evaluation of morphology and flow in the coronary arteries and for assessment of function and perfusion of the myocardium.
Reproducibility of exercise-induced ventricular arrhythmia after myocardial infarction

To evaluate the reproducibility of exercise-induced ventricular arrhythmia, 155 men with a mean age of 53 +/- 8 years underwent serial exercise testing 3 to 52 weeks after myocardial infarction. The reproducibility of categorical test responses, that is, the presence or absence of ventricular arrhythmia, was evaluated with the kappa coefficient, which considers negative as well as possible test responses and expresses reproducibility above the chance level. Reproducibility was highest at an intertest interval of 1 to 5 days and was not enhanced by further categorizing premature ventricular complexes as simple or complex based on their frequency or configuration. Continuous response measures such as frequency of premature ventricular complexes yielded higher reproducibility than categorical responses. Continuous response measures appear preferable to categorical responses for evaluating the clinical significance and response to antiarrhythmic therapy of ventricular arrhythmias.
Isaiah 56:1-8 and the Redefining of the Restoration Judean Community

This article argues that the prophetic oracle of Isaiah 56:1-8 was intended to redefine the social boundaries of the Judean community in the early second temple period. This prophecy offers an alternative viewpoint to the nationalist and exclusionist views of Ezra and Nehemiah as to who can be a member of the Judean community. The position taken by this passage utilizes the images of the eunuch and the foreigner to reveal conflicts over land possession and the reproduction and socialization of children. It is argued that the exilic principles of community membership revolve around the issues of "purification" (in the exile) and the exclusion of outsiders who did not share this experience, and "loyalty," seen as endogamy and the reproduction and socialization of children to preserve the ethnic purity of the exilic community. The cases of the eunuch and the foreigner (convert) challenge both these principles and offer alternative principles of "loyalty" by relocating the markers of community membership into...
Partial destruction of USY and its effect on the hydrothermal stability

Abstract The hydrothermal stabilities of ultrastabilized Y under 100% steam were examined in relation with the results of XRD, chemical analyses, and MAS n.m.r. The hydrothermal stability of USY was affected mainly by the retention of crystallinity, but not by the amounts of residual alkali metal oxides. The populations of Si(3Al) in sodium Y affect the partial destruction of structure during the dealumination. Some of Si(3Al) units were converted to nonframework Si(4Al) units and left the vacants larger than four OH nests in the zeolite framework, which causes the formation of secondary pore systems and amorphous fraction.
External beam accelerated partial-breast irradiation using 32 gy in 8 twice-daily fractions: 5-year results of a prospective study.

Purpose External beam accelerated partial breast irradiation (APBI) is an increasingly popular technique for treatment of patients with early stage breast cancer following breast-conserving surgery. Here we present 5-year results of a prospective trial. Methods and Materials From October 2003 through November 2005, 98 evaluable patients with stage I breast cancer were enrolled in the first dose step (32 Gy delivered in 8 twice-daily fractions) of a prospective, multi-institutional, dose escalation clinical trial of 3-dimensional conformal external beam APBI (3D-APBI). Median age was 61 years; median tumor size was 0.8 cm; 89% of tumors were estrogen receptor positive; 10% had a triple-negative phenotype; and 1% had a HER-2-positive subtype. Median follow-up was 71 months (range, 2-88 months; interquartile range, 64-75 months). Results Five patients developed ipsilateral breast tumor recurrence (IBTR), for a 5-year actuarial IBTR rate of 5% (95% confidence interval [CI], 1%-10%). Three of these cases occurred in patients with triple-negative disease and 2 in non-triple-negative patients, for 5-year actuarial IBTR rates of 33% (95% CI, 0%-57%) and 2% (95% CI, 0%-6%; P P =.0537). Conclusions Overall outcomes were excellent, particularly for patients with estrogen receptor-positive disease. Patients in this study with triple-negative breast cancer had a significantly higher IBTR rate than patients with other receptor phenotypes when treated with 3D-APBI. Larger, prospective 3D-APBI clinical trials should continue to evaluate the effect of hormone receptor phenotype on IBTR rates.
AutoCAD Add-on for Simplified Design of Microfluidic Devices

The development of polydimethylsiloxane-based microfluidic devices with integrated controlling components has led to the translation of many bench-top biological processes to microdevice platforms. While many biomedical scientists recognize the applicability of microdevices to their research, their lack of engineering background and training in computer-aided design (CAD) makes them unable to design the desired microchips using AutoCAD software, which is the universal first step for chip fabrication. In this work, we used the .NET platform to develop a user-friendly AutoCAD add-on feature that includes the ability to create channels, loops, valves, and punches, as well as channel to loop connections, valve to channel connections, valve to loop connections, channel to channel connections, and punch to channel connections. This add-on feature greatly simplifies the process of AutoCAD drawing, which allows people not familiar with AutoCAD to easily learn to use the add-on. For testing purposes, we used the add-on to draw a series of two-layer microchips designed to synthesize luciferase using a coupled transcription-translation system with different capacities. The AutoCAD files for the microfluidic designs were then sent to the Stanford Microfluidics Foundry for chip fabrication. Our results show that the quantity of luciferase produced on the chip is proportional to the capacity of the reaction loop.
Estimating the Demand for an on-Farm Recreational Service

rT nHIS note reports the results of a study having the objective of determining the characteristics of market demand for the recreational services of on-farm golf courses in North Carolina [4].1 Conceptually, the demand for a recreational service such as golfing presents no special problems. One would expect the usual demand shifters-population, income, prices of closely-related goods, and tastes and preferences -to be the factors that determine the level of demand. In estimating the demand for golfing services, however, one faces problems that are somewhat different from those confronted in estimating the demand for most "normal" economic goods.2 One distinguishing characteristic of golfing (and other recreational) services is that the consumer must provide a significant amount of time during the process of consuming the good. Since time is an economic good, it commands a price and consequently its value (opportunity cost) must be considered in estimating demand. Another distinguishing characteristic of the golfing service is that it is immobile. Hence, consumption must occur at the point of supply. That is, the consumer must transport himself to the product rather than having the product transported to him. As a result, transportation costs become an important consideration in the price of the good to the consumer, whereas they are generally small enough to be ignored in the demand for other goods.
Response of the Amphipod Diporeia spp. to Various Stressors: Cadmium, Salinity, and Temperature

The tolerance of the amphipod Diporeia spp. (formerly Pontoporeia hoyi) to salinity and temperature and the acute toxicity of cadmium were determined by laboratory tests. No mortality occurred during 28 d exposure at a salinity of 20 g sea salt L−1. Slower swimming and mortality occurred when the salinity was increased to 25 g sea salt L−1. In freshwater, Diporeia tolerate a temperature of 26°C but exhibit 82% mortality within 24 h at 28°C. Thus, Diporeia collected from southern Lake Michigan demonstrate a significant salinity and thermal tolerance. Sensitivity to cadmium depends on both the temperature and the salinity of the exposure solution. At 4°C in fresh water, the 96 h LC50 for Cd, administered as CdCl2, was 0.78 mg Cd•L−1 (95% C.I. 0.40-1.02 mg Cd-L•−1). At 15°C, it decreased to 0.065 mg Cd•L−1 (95% C.I. 0.051-0.074 mg Cd•L−1). In salt water, the tolerance to Cd at 4°C [96 h LC50 of 49.4 mg Cd•L−1 (95% C.I. 45.3–52.7 mg Cd•L−1)] was much greater than in fresh water and decreased with increasing temperature, 96 h LC50 of 6.02 mg Cd•L−1 (95% C.I. 6.02–7.32 mg Cd•L−1) at 15°C. Overall sensitivity to cadmium increases with increasing temperature and decreases with increasing salinity within the salinity tolerance of the organism. Diporeia are important Great Lakes benthos exposed to a wide range of contaminants. While Diporeia's sensitivity to contaminants has been implied, this work provides supportive data on the sensitivity of Diporeia to selected stressors.
Studies of scintillating fibers readout with visible light photon counters

A large tracking detector consisting of scintillating plastic optical fibers has been chosen by the D0 collaboration as a part of a planned upgrade at the Fermilab Tevatron. The tracker will utilize multiclad scintillating fibers and optical waveguides and state of the art photosensors called visible light photon counters (VLPC). In this paper we present some general characteristics of fiber detectors and then describe recent measurements of system performance based on data from the 3072 channel cosmic ray test stand. Based upon these studies, fiber detectors are expected to perform very well for collider operation, and excellent performance is also expected for fixed target applications.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.

A Monte Carlo simulation of the effect of ion self-collisions on the ion velocity distribution function in the high-latitude F-region

Non-Maxwellian ion velocity distribution functions have been theoretically predicted and confirmed by observations, to occur at high latitudes. These distributions deviate from Maxwellian due to the combined effect of the E×B drift and ion-neutral collisions. The majority of previous literature, in which the effect of ion self-collisions was neglected, established a clear picture for the ion distribution under a wide range of conditions. At high altitudes and/or for solar maximum conditions, the ion-to-neutral density ratio increases and, hence, the role of ion self-collisions becomes appreciable. A Monte Carlo simulation was used to investigate the behavior of O+ ions that are E×B-drifting through a background of neutral O, with the effect of O+ (Coulomb) self-collisions included. Wide ranges of the ion-to-neutral density ratio n i /n n and the electrostatic field E were considered in order to investigate the change of ion behavior with solar cycle and with altitude. For low altitudes and/or solar minimum (n i /n n \leq10−5), the effect of self-collisions is negligible. For higher values of n i /n n , the effect of self-collisions becomes significant and, hence, the non-Maxwellian features of the O+ distribution are reduced. For example, the parallel temperature Ti\Vert increases, the perpendicular temperature Ti⊥ decreases, the temperature anisotropy approaches unity and the toroidal features of the ion distribution function become less pronounced. Also, as E increases, the ion-neutral collision rate increases, while the ion-ion collision rate decreases. Therefore, the effect of ion self-collisions is reduced. Finally, the Monte Carlo results were compared to those that used simplified collision models in order to assess their validity. In general, the simple collision models tend to be more accurate for low E and for high n i /n n .
Direct numerical simulation of turbulence-radiation interactions in homogeneous nonpremixed combustion systems

Abstract An important issue in chemically reacting turbulent flows is the interaction between turbulence and radiation (turbulence–radiation interactions—TRI). TRI arises from highly nonlinear coupling between fluctuations in temperature and species composition with the fluctuations of radiative intensity. Here direct numerical simulation (DNS) has been employed to investigate TRI in a statistically homogeneous nonpremixed system. A photon Monte Carlo method has been used to solve the radiative transfer equation (RTE). Radiation properties correspond to a nonscattering fictitious gray gas with a Planck-mean absorption coefficient that mimics that of typical hydrocarbon-air combustion products. Individual contributions of emission and absorption TRI have been isolated and quantified. The temperature self-correlation, the absorption coefficient-Planck function correlation, and the absorption coefficient-intensity correlation have been examined for intermediate-to-large values of the optical thickness, and contributions from all three correlations have been found to be significant. Emission TRI has also been estimated analytically using a β PDF model. The β PDF results are in good agreement with DNS results. This suggests that relatively simple models for emission TRI in nonpremixed systems might be developed based on a modeled equation for mixture fraction variance.
Anthocyanins facilitate tungsten accumulation in Brassica

Accumulation of molybdenum in Brassica was recently found to be correlated with anthocyanin content, involving the formation of a blue complex. Here the role of anthocyanins in tungsten sequestration was investigated using three species of Brassica : B. rapa (cv. Fast plants), B. juncea (Indian mustard) and B. oleracea (red cabbage). Seedlings of B. rapa and B. juncea turned blue when supplied with colourless tungstate. The blue compound co-localized with anthocyanins in the peripheral cell layers, and the degree of blueness was correlated with anthocyanin content. The direct involvement of anthocyanins in the blue coloration was evident when purified anthocyanins showed a colour change from pink to blue in vitro upon addition of tungstate, over a wide pH range. Anthocyanin production was upregulated 3-fold by W in B. juncea , possibly reflecting a function for anthocyanins in W tolerance or sequestration. The presence of anthocyanins facilitated W accumulation in B. rapa : anthocyanin-containing seedlings accumulated 3-fold more W than an anthocyaninless mutant. There was no correlation between anthocyanin content and W tolerance under these conditions. The nature of the interaction between anthocyanins and tungstate was investigated. X-ray absorption spectroscopy showed no change in the local chemical environment of W upon uptake of tungstate by the plant; HPLC analysis of purified anthocyanin with or without tungstate showed no peak shift after metal treatment.
Analyzing multivariate output

This paper gives an overview of multivariate statistical techniques that can be useful for analyzing discrete-event simulation output, and describes some of the latest directions in research on multivariate output analysis. A general discussion is given of constructing joint confidence regions on the mean vector of multivariate output from independent replications of terminating models. The multivariate batch means method of simultaneous estimation of means from one long run of steady-state simulation models is described. References are also given for autoregressive, spectral analysis and regenerative methods of inference, as well as variance-reduction and sequential techniques.
Balloon dilatation of long-segment tracheal stenoses

Although a rare anomaly, congenital tracheal stenosis is associated with a high mortality. Surgical approaches proposed for this life-threatening lesion have included resection of localized stenoses; tracheoplasty involving interposition of cartilage, periosteum, or pericardium via an anterior tracheal split; or esophageal anastomosis to a posterior tracheal split. None of these techniques have provided uniformly satisfactory results, and all entail significant morbidity associated with the tracheal anastomosis. We have used endoscopic balloon dilatation in four children with critical airway obstruction from long-segment tracheal stenoses. In each of these patients, symptoms began early in life (from 2 weeks to 6 months of age) and consisted of respiratory distress from upper airway obstruction or recurrent episodes of stridor and chest retractions requiring hospitalization. The location of the tracheal stenoses varied, involving the upper third, middle third, middle half, and distal half of the trachea in the patients encountered. At bronchoscopy, the lumen was judged to be less than or equal to 1 mm in three of these patients. Dilatation was accomplished using Gruentzig balloon catheters in sizes ranging from 3 mm to (eventually) 8 mm, and produced a posterior split in the complete tracheal rings responsible for the stenosis in all patients, resulting in great increases in airway lumen. All children were improved following balloon dilatation, and three are currently doing well at 2.5, 3.0, and 3.0+ years postdilatation. One infant eventually died of airway obstruction incurred by severe bronchomalacia distal to the tip of an endotracheal tube that had been passed to the carina after sequential balloon dilatations.(ABSTRACT TRUNCATED AT 250 WORDS)
Design of Nanostructured Solar Cells Using Coupled Optical and Electrical Modeling

Nanostructured light trapping has emerged as a promising route toward improved efficiency in solar cells. We use coupled optical and electrical modeling to guide optimization of such nanostructures. We study thin-film n-i-p a-Si:H devices and demonstrate that nanostructures can be tailored to minimize absorption in the doped a-Si:H, improving carrier collection efficiency. This suggests a method for device optimization in which optical design not only maximizes absorption, but also ensures resulting carriers are efficiently collected.
The Monoterpene Citronellol, as a Male Sex Attractant of the Twospotted Spider Mite, Tetranychus urticae (Acarina: Tetranychidae)

Males of Tetranychus urticae Koch are strongly attracted to pharate females. The male will remain and guard the pharate female until emergence of the adult, when mating occurs. The sesquiterpene alcohols farnesol and nerolidol were previously reported as male attractants of the twospotted spider mite. The monoterpene alcohol citronellol was isolated and identified from pharate females. Males were highly attracted to 10 ppm synthetic citronellol in bioassays.
Contextualism about ‘might’ and says-that ascriptions

Contextualism about ‘might’ says that the property that ‘might’ expresses varies from context to context. I argue against contextualism. I focus on problems that contextualism apparently has with attitude ascriptions in which ‘might’ appears in an embedded ‘that’-clause. I argue that contextualists can deal rather easily with many of these problems, but I also argue that serious difficulties remain with collective and quantified says-that ascriptions. Herman Cappelen and John Hawthorne atempt to deal with these remaining problems, but I argue that their attempt fails.
Design and development of high efficiency solar cells using thin film GaAs on nanostructured silicon

Multi-junction solar cells are being explored extensively as an alternative to long existing silicon photovoltaic technology. At present, this technology is very expensive due to high Ge and GaAs material cost, however, excellent quality GaAs thin films grown on Si substrates is an alternative route to addresses such challenges. In this report, the design and development of efficient solar cells using GaAs thin films on high aspect ratio Si nanostructures has been investigated. Such nanostructures can be used as template layers for defect reduction as well as sacrificial layers. An initial work starts with the MOCVD growth of thin films of GaAs on nanostructured Si substrate. Photoluminance studies show promising results with stronger impurity transition peak with lower full width at half maximum. Optical characterization confirms that the GaAs band-edge was consistent with crystalline GaAs substrates. An effective technique for the growth optimization on nanostructured Si surfaces can lead to improved quality material for the production of high efficiency solar cells. The fabricated devices showed promising results for commercial applications.
A comparative analysis of the outcomes of aortic cuffs and converters for endovascular graft migration.

Objective Proximal attachment failure, often leading to graft migration, is a severe complication of endovascular aneurysm repair (EVAR). Aortic cuffs have been used to treat proximal attachment failure with mixed results. The Zenith Renu AAA Ancillary Graft (Cook Inc, Bloomington, Ind) is available in two configurations: converter and main body extension. Both provide proximal extension with active fixation for the treatment of pre-existing endovascular grafts with failed or failing proximal fixation or seal in patients who are not surgical candidates. We prospectively compared the outcomes of patient treatment with these two device configurations. Methods From September 2005 to May 2008, a prospective, nonrandomized, postmarket registry was conducted to collect data from 151 patients treated at 95 institutions for proximal aortic endovascular graft failure using the Renu graft. Treatment indications included inadequate proximal fixation or seal, for example, migration, and type I and III endoleak. A total of 136 patients (90%) had migration, 111 (74%) had endoleak, and 94 (62%) had endoleaks and graft migration. AneuRx grafts were present in 126 patients (83%), of which 89 (59%) were treated with a converter and 62 (41%) with a main body extension. Outcomes using converters vs main body extensions for endoleak rates, changes in aneurysm size, and ruptures were compared. Results Preprocedural demographics between the two groups did not differ significantly. Procedural success rates were 98% for the converter group and 100% for the main body extension group. At a mean follow-up of 12.8 ± 7.5 months, no type III endoleaks (0%)were identified in the converter group, and five (8%) were identified in the main body extension group. There were no aneurysm ruptures in patients treated with converters (0%) and three ruptures (5%) in patients treated with main body extensions. Each patient with aneurysm rupture had been treated with a Renu main body extension, developed a type III endoleak, and underwent surgical conversion. Two of the three patients died postoperatively. Conclusions Proximal attachment failure and graft migration are potentially lethal complications of EVAR. Proximal graft extension using an aortic cuff is the easiest technique for salvaging an endovascular graft. Unfortunately, it has a predictable failure mode (development of a type III endoleak due to component separation) and is associated with a significantly higher failure rate than with the use of a converter. EVAR salvage with a converter and a femorofemoral bypass is a more complex but superior option for endovascular graft salvage.
Supercomputing and drug discovery research

A primary role of computational science and supercomputing technology in pharmaceutical research is to expedite the discovery and development process using a balance of database applications, data generation applications, and data analysis and visualization applications. Data generation applications include familiar algorithms based on physical theory, such as molecular mechanics and quantum mechanics. The usefulness of computational chemistry to the pharmaceutical (and chemical) industry depends on its ability to provide knowledge about the structure and properties of substances and the transformations they undergo. The complexity of realistic model calculations and the time-critical nature of the results require high-performance computing to discover and test ideas for novel compounds that will be useful in therapeutic intervention.
Dominica — geographic isolation and tourism prospects

Abstract Dominica is a small Caribbean Island nation seeking to diversify its economy at least in part through encouragement of ‘eco-tourism’. There is no reason why this should not be accomplished. However, tourism is no panacea for economic ills. If Dominica is going to succeed in developing tourism, it must avoid the temptation to assume that problems will take care of themselves as development proceeds. G.W. Burnett and Muzaffer Uysal of the Department of Parks, Recreation and Tourism Management at Clemson University explore the nature of Dominica's tourism industry and the geographic factors which affect its organization and future.
Decentralized coordination for multirobot exploration

Abstract In order for multiple robots to explore an unknown environment, they need a strategy for cooperation. We propose a strategy where robots share perceptual information but maintain separate maps. These robots make independent decisions about where to explore using frontier-based exploration. This allows each robot to use the information from other robots while retaining the capability to explore independently. As a result, the multirobot team is robust to the loss of communications or the loss of individual robots. We have implemented this system on real robots and have demonstrated that they can explore and map indoor environments effectively.
Some maize sex-related mutants

Four morphological sex-related mutants in maize (Zea mays L.) are described. Three have arisen in materials containing transposons and one (Mn::Uq) is known to be segregating with a transposon. The Mn::Uq and the RSS affect pollen activity, fw affects tassel silking, and ba4 lacks ear initials. These mutants have been studied by genetic means, and some interactions between double mutants have been investigated.
Infrared spectra of carbon monoxide on ruthenium predicted by intermedion theory

Abstract The infrared spectra of weakly bonded species from CO in contact with adsorbents containing Cr, Fe, Co and Ni were characterized as “intermedions.” The vibrational frequencies of these CO intermedions were related to the electronic energy levels of gaseous ions of these metals. From this relationship and the electronic energy levels of Ru II and Ru III, the vibrational frequencies were calculated for CO intermedions on adsorbents containing ruthenium. The infrared spectra of weakly bonded CO on adsorbents containing Ru showed bands at the calculated frequencies of 2146, 2074, and 2041 cm−1. The vibrational frequencies of species that are strongly bonded to the surface, that is, not readily removed by evacuation at room temperature are reported also.
Methods for Detecting Associations with Rare Variants for Common Diseases : Application to Analysis of Sequence Data

Although whole-genome association studies using tagSNPs are a powerful approach for detecting common variants, they are underpowered for detecting associations with rare variants. Recent studies have demonstrated that common diseases can be due to functional variants with a wide spectrum of allele frequencies, ranging from rare to common. An effective way to identify rare variants is through direct sequencing. The development of cost-effective sequencing technologies enables association studies to use sequence data from candidate genes and, in the future, from the entire genome. Although methods used for analysis of common variants are applicable to sequence data, their performance might not be optimal. In this study, it is shown that the collapsing method, which involves collapsing genotypes across variants and applying a univariate test, is powerful for analyzing rare variants, whereas multivariate analysis is robust against inclusion of noncausal variants. Both methods are superior to analyzing each variant individually with univariate tests. In order to unify the advantages of both collapsing and multiple-marker tests, we developed the Combined Multivariate and Collapsing (CMC) method and demonstrated that the CMC method is both powerful and robust. The CMC method can be applied to either candidate-gene or whole-genome sequence data.
Pathological Effects of the Supermaximum Prison

The drawings of Todd (Hyung-Rae) Tarselli, a prisoner confined in a Pennsylvania “close-security” or “supermaximum” prison, tell a story—one that graphically portrays the devastating effects of a prison on the mental health of its inmates.
Dietary prescription adherence and non-structured physical activity following weight loss with and without aerobic exercise

Objectives To compare the effects of weight loss with and without exercise on 1) dietary prescription adherence and 2) non-structured activity in postmenopausal women.
Matthew's Titulus and Psalm 2's King on Mount Zion

Origen, Augustine, Aquinas, and others thought that the titulus crucis was an ironic divine decree that recalled Ps 2:6: “I have set my king on Zion, my holy hill.” Although this reading is no longer mentioned in modern commentaries on Matthew, this article attempts to demonstrate that it is, in fact, quite plausible, given larger Matthean themes. The argument begins by suggesting that Matthew’s passion narrative and crucifixion scene frequently recall the enthronement scenario in Ps 2:6–8—including the opposition to God and God’s Messiah in vv. 1–3. Then it suggests that Matthew makes the crucifixion the climax of the opposition to Jesus as described in Psalm 2 and shapes the titulus into an ironic proclamation of the kingship of Jesus. The article thus concludes that Origen’s proposed linkage between Psalm 2 and Matthew’s inscription can be defended intratextually, if not intertextually.
EMGWS, D1 projectile tests

The 90 mm EMGWS D1 projectile is an unguided projectile that is designed for launch from an electromagnetic gun to achieve significant armor penetration. The 90 mm D1 type II workhorse projectile is used to test material strength, fabrication techniques, and projectile structural integrity.

The total weight of the projectile is 2.0 kg to attain a muzzle velocity of 3.0 km/s from a 9 MJ EM gun. The type II projectile configuration employs a tungsten nosetip plus 12 segmented tungsten penetrators, a two-piece aluminium discarding sabot, an aluminium pusher plate, and a nylon orbturator. The pusher plate, can incorporate either a solid or plasma armature. >
Clinical utility of screening laboratory tests in pediatric psychiatric patients presenting to the emergency department for medical clearance.

Study objective We assess whether screening laboratory tests obtained to medically clear pediatric psychiatric patients altered management or disposition. Methods This was a retrospective chart review of consecutive patients younger than 18 years and presenting to an academic pediatric emergency department for medical clearance of an acute psychiatric emergency potentially requiring an involuntary hold (danger to self, danger to others, grave disability) from July 2009 to December 2010. Patients were identified by discharge diagnosis codes. History and physical examination and screening laboratory tests were reviewed for changes in management or disposition. Further analysis compared length of stay according to type of laboratory test performed. To avoid missing patients presenting with or for evaluation of an involuntary hold for whom an organic cause was diagnosed, charts with psychiatric chief complaints were reviewed for the same period. Results One thousand eighty-two visits resulting in 13,725 individual laboratory tests were analyzed. Of 871 visits with laboratory tests performed, abnormal laboratory tests were associated with 7 disposition changes (0.8%) and 50 management changes (5.7%) not associated with a disposition change. Twenty-five patients with noncontributory history and physical examination results had management changes, all non-urgent. One patient with a noncontributory history and physical examination result had a disposition-changing laboratory result, a positive urine pregnancy test. Patients who had any screening test performed had a longer length of stay than patients without testing (117 minutes longer; 95% confidence interval 109.7 to 124.4 minutes). In charts reviewed according to chief complaint, no patient was found to have an organic cause of their symptoms according to only screening tests. Conclusion Screening laboratory tests resulted in few management and disposition changes in patients with noncontributory history and physical examination results but were associated with increased length of stay.
Agricultural exports as an instrument of diplomacy

Abstract The use of national resources as diplomatic weapons has gained ground since OPEC's successes. In this article William Schneider, Jr discusses the role that agricultural exports could play in US foreign policy. He concludes that it could have significant short-term impacts and would counter-balance attempts by other producers to interrupt exports of their indigenous raw materials.
World cities in poor countries: conclusions from case studies of the principal regional and global players

This is a brief report on a study of world cities in the under-researched poor countries. Whereas previous work has focused rather haphazardly on one or a few cities beyond the West, this is the first study to systematically cover such ‘second-tier’ world cities. Fourteen leading authorities from diverse backgrounds bring their expertise to bear on twelve world cities across four continents. Alongside the economic, they consider the political and cultural role these cities play within their regions and at the global level. The study leads to three principal conclusions: (1) these cities are extraordinarily diverse; (2) the city centers have become elite enclaves; and (3) along with the forces of globalization, the state and popular movements are important actors. These findings indicate the need for research that moves beyond the focus on globalization to take into account the multiple forces shaping world cities. And they demonstrate the benefits of overcoming an ethnocentrism in urban studies that privileges Western cities as locales of study and sources of generalization. Ce compte rendu resume une etude sur les grandes villes mondiales situees dans les pays pauvres delaisses par les recherches. Tandis que les travaux precedents s'etaient consacres, plutot au hasard, a quelques grandes villes hors d'Occident, cette etude est la premiere a couvrir systematiquement les villes mondiales ‘de second ordre’. Quatorze auteurs eminents d'appartenances diverses apportent leur expertise a l'egard de douze grandes villes mondiales reparties sur quatre continents. Ces chercheurs s'interessent non seulement a la fonction economique, mais aussi aux roles politique et culturel de ces villes au niveau regional et international. Trois conclusions majeures se degagent: ces villes sont extraordinairement diverses, les centres-villes sont devenus des enclaves pour elites et, parallelement aux poussees de la mondialisation, l'Etat et les mouvements populaires sont des acteurs importants. Ces resultats montrent la necessite de realiser des recherches qui depassent le seul plan de la mondialisation pour tenir compte des forces multiples qui faconnent les villes mondiales. De plus, ils prouvent qu'il vaut mieux s'emanciper de l'ethnocentrisme des etudes urbaines, lequel privilegie les villes occidentales comme sites d'etude et sources de generalisation.
Passive compliance versus active compliance in robot‐based automated assembly systems

Industrial robots have found great potential in applications to assembly‐line automation. Programmable robot‐based assembly systems are often needed, in particular for circumstances in which special assembly equipments is not available or well‐trained operators could not be employed economically. Robots with enough compliance can perform not only classic automation tasks, such as spot welding, cargo carrying, etc., but also can operate those tasks which demand the compliant motion capacity of robots. Therefore, the research on robot compliance is especially important for parts assembly by robots, where robot compliant motions and manipulations are essential requirements. This paper presents a number of important issues in robot compliance research, including the specification of robot end‐effector compliance; properties of a robot compliance matrix at its end‐effector; discussions on passive compliance and active compliance and their comparisons; and derivation of the compliance at the end‐effector required for tasks.

Some consequences of the decay modes and production of the new heavy bosons

An investigation is made of the consequences following from the production and decay of the recently discovered heavy bosons. It is found that various correlation experiments can determine their spins and parities and their polarization states arising from the production process. Further, it is shown that a study of leptonic decay modes can throw significant light on the electromagnetic structure of the leptons.
Measurement of the frequency dependence of the phonon damping function by Raman scattering from polaritons in GaP

Abstract We present a new method of measuring the phonon damping function Γ(ω) as a function of frequency by means of Raman scattering from phonon-polaritons. This experimental method is applied to GaP and we obtain Γ(ω) vs. ω for the transverse optical (TO) phonons of GaP at room temperature. The improved sensitivity and frequency resolution of this technique allows one to observe fine details in the structure of Γ(ω) vs. ω which were not revealed by previous studies.
Improvement in Interstitial Cystitis Symptom Scores During Treatment With Oral L-Arginine

AbstractPurpose: Urinary nitric oxide synthase activity is decreased in patients with interstitial cystitis. Since nitric oxide may be an important determinant of the symptoms and immunological responses associated with interstitial cystitis, patients with this disease were treated with oral L-arginine, the substrate for nitric oxide synthase.Materials and Methods: Ten patients took 1.5 gm. L-arginine orally daily for 6 months. Interstitial cystitis symptoms were surveyed before and during the 6-month trial.Results: Oral L-arginine treatment resulted in a significant decrease in urinary voiding discomfort, lower abdominal pain and vaginal/urethral pain. Urinary frequency during the day and night also significantly decreased.Conclusions: This self-controlled study provides evidence that long-term oral L-arginine improves interstitial cystitis related symptoms.
Dynamic Behavior of a Bilinear Hysteretic Elasto-Plastic Oscillator, Part II: Oscillations Under Periodic Impulse Forcing

Abstract The dynamic response of a single-degree-of-freedom elasto-plastic oscillator with kinematic hardening is analyzed in this paper under two kinds of periodic impulse forcing: (a) direct and (b) parametric. In the first case, impulses of constant amplitude are applied periodically to the system and the resulting motion is analyzed using eigenvalues of the linearized Poincare map, and a boundary curve separating the stable and unstable periodic oscillations is obtained in the forcing parameter space. In the second case, the impulse-amplitude is proportional to the displacement of the oscillator. The forced response is extremely complex in this case. The motion undergoes numerous bifurcations, from periodic to quasi-periodic to chaos-like motions.
Controlling morphology and enhancing electrochemical performance of cobalt oxide by addition of graphite

Abstract Co 3 O 4 nanowire, nanoparticle network, and Co 3 O 4 /graphite nanocomposite were synthesized via a hydrothermal route accompanied with a post-annealing step. The Co 3 O 4 nanowire was formed without adding graphite; after introducing graphite, the morphology of the Co 3 O 4 nanocomposite changed to a network through the partial overlapping of nanoparticles. The electrochemical properties of the samples were studied as anode materials in lithium-ion batteries. The Co 3 O 4 /graphite nanocomposite outperforms two different pure Co 3 O 4 samples by showing superior Li-battery performance with dramatically enhanced cyclic performance at a current density of 500 mA/g and excellent rate performance. Its reversible capacity remains as high as 551 mA h/g after 50th cycle.
Stereo Matching with Nonlinear Diffusion

One of the central problems in stereo matching (and other image registration tasks) is the selection of optimal window sizes for comparing image regions. This paper addresses this problem with some novel algorithms based on iteratively diffusing support at different disparity hypotheses, and locally controlling the amount of diffusion based on the current quality of the disparity estimate. It also develops a novel Bayesian estimation technique, which significantly outperforms techniques based on area-based matching (SSD) and regular diffusion. We provide experimental results on both synthetic and real stereo image pairs.
The role of marriage in linguistic contact and variation: Two Hmong dialects in Texas1

The role of marriage in linguistic contact and variation has been under-represented in sociolinguistic research. In any practice-based analysis, individual interactions and relationships are crucial. Therefore, marriage relationships – small but intense communities of practice – deserve variationist attention for their role in dialect construction and identity. This investigation of cross-dialectal marriages explores how dialect practices and choices are negotiated between partners. The results show the importance of viewing this linguistic behavior in terms of community ideology, culture, and individual choice, rather than primarily as a matter of the amount and intensity of contact. Likewise, the study shows how less commonly studied minority communities can bring new insights to the study of dialect acquisition and linguistic contact. Specifically, this investigation focuses on marriages between speakers of two different dialects of Hmong, a Hmong-Mien language of Southeast Asia. On the basis of home visits to ten Hmong immigrant households in Texas, the study analyzes lexical and phonetic contrasts and ethnographic interviews. Results suggest that macro-level shifts in Hmong social organization and gender roles are being reflected and constructed by gendered, marriage-level dialect practices. The linguistic behavior in these marriages is best viewed as a matter of community ideology in tension with individual choice: individual wives are choosing to challenge the traditional Hmong ideology regarding language behavior in cross-dialect marriages.
Spatial-temporal nonlinear filtering based on hierarchical statistical models

A hierarchical statistical model is made up generically of a data model, a process model, and occasionally a prior model for all the unknown parameters. The process model, known as the state equations in the filtering literature, is where most of the scientist's physical/chemical/biological knowledge about the problem is used. In the case of a dynamically changing configuration of objects moving through a spatial domain of interest, that knowledge is summarized through equations of motion with random perturbations. In this paper, our interest is in dynamically filtering noisy observations on these objects, where the state equations are nonlinear. Two recent methods of filtering, the Unscented Particle filter (UPF) and the Unscented Kalman filter, are presented and compared to the better known Extended Kalman filter. Other sources of nonlinearity arise when we wish to estimate nonlinear functions of the objects positions; it is here where the UPF shows its superiority, since optimal estimates and associated variances are straightforward to obtain. The longer computing time needed for the UPF is often not a big issue, with the ever faster processors that are available. This paper is a review of spatial-temporal nonlinear filtering, and we illustrate it in a Command and Control setting where the objects are highly mobile weapons, and the nonlinear function of object locations is a two-dimensional surface known as the danger-potential field.
Relationship between CFTR and CTRC Variants and the Clinical Phenotype in Late-Onset Cystic Fibrosis Disease with Chronic Pancreatitis

Cystic fibrosis (CF), the most common autosomal recessive disease in whites, is caused by mutations in the CF transmembrane conductance regulator (CFTR). So far, >1900 mutations have been described, most of which are nonsense, missense, and frameshift, and can lead to severe phenotypes, reducing the level of function of the CFTR protein. Synonymous variations are usually considered silent without pathogenic effects. However, synonymous mutations exhibiting exon skipping as a consequence of aberrant splicing of pre-mRNA differ. Herein, we describe the effect of the aberrant splicing of the c.273G>C (G91G) synonymous variation found in a 9-year-old white (ΔF508) patient affected by CF and pancreatitis associated with a variant in chymotrypsin C (CTRC). Magnetic resonance imaging showed an atrophic pancreatic gland with substitution of the pancreatic parenchyma with three cysts. Genetic examination revealed compound heterozygosity for the c.1521_1523delCTT (ΔF508) pathogenic variant and the c.273G>C (G91G) variant in CFTR. Sweat test results confirmed the diagnosis of CF. We have thus identified a synonymous variation (G91G) causing the skipping of exon 3 in a CF patient carrying the ΔF508 mutation. However, the clinical phenotype with pancreatic symptoms encouraged us to investigate a panel of pancreas-related genes, which resulted in finding a known sequence variation inside CTRC. We further discuss the role of these variants and their possible interactions in determining the current phenotype.
