Abstract

We have used the Fermilab 30-in. bubble-chamber-hybrid spectrometer to study neutral-strange-particle production in the interactions of 200-GeV/c protons and + and K+ mesons with nuclei of gold, silver, and magnesium. Average multiplicities and inclusive cross sections for K0 and are measured, and a power law is found to give a good description of their A dependence. The exponent characterizing the A dependence is consistent with being the same for K0 and production, and also the same for proton and + beams. Average K0 and multiplicities, as well as their ratio, have been measured as functions of the numbers of projectile collisions p and secondary collisions s in the nucleus, and indicate that rescattering contributes significantly to enhancement of production but not to K0 production. The properties of events with multiple K0's or also corroborate this conclusion. K0 rapidities are in the central region and decrease gently with increasing p, while rapidities are in the target-fragmentation region and are independent of p. K0 and multiplicities increase with the rapidity loss of the projectile, but their rapidities do not.

Abstract

The Numisheet 2005 Benchmark [sharp/mesh/hash_synonym]3 consists of a two stage forming process performed on four materials (three steels and one aluminum). Stage 1 consists of forming channel sections in a channel draw die with variable penetration draw beads, and is described in detail in another report. In Stage 2, described here, the samples from Stage 1 are trimmed and subjected to near plane strain Marciniak style cup test. The plane straining is performed in 0 ° and 90 ° orientations. After failure limits for the cup depths are determined, trimmed samples from Stage 1 are strained to specific cup depths (less than the depth of failure) and stresses are measured in situ using a unique X-ray diffraction technique. The results are repeatable and consistent with expectations. The goal of this benchmark is to check not only the strain achieved during a two stage forming process, but also to develop data that include the stresses achieved. These results may then be used to further test the ability of numerical models to predict not only strains but stresses during a forming process. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]

Abstract

In an experiment with the 30-inch Hybrid Spectrometer at Fermilab we have obtained the inclusive and semi-inclusive production cross sections of the ϱ0 meson using a conventional background subtraction technique. Production cross sections for the ϱ0 are derived as a function of the Feynman scaling variablex, and the transverse variablespt2 andEt=(pt2+M2)1/2. The longitudinal distributions are compared with the (1−x) dependence of the proton and meson valence quark structure functions, using various forms of recombination and fragmentation models. The transverse distributions are compared with thermodynamic models. We give density matrix elements for the ϱ0 production from pions in the extreme forward region.

Abstract

The ratio of hadronic p+/p- production has been studied in the target fragmentation region of p+p, p-p,K+p andp p collisions at 147 GeV/c beam momentum. The difference between this ratio in the p+p and p-p data is less than at lower energies but still present. No difference exists anymore for the p+/p- ratio at this energy betweenK+p andpp collisions. Exclusion of diffraction dissociation and resonance production does not change the main conclusions. The energy dependence of the ratio for p+p and p-p collisions gives evidence for a universal asymptotic ratio for all beams. Thept-dependence at low-pt is in agreement with the expectation from geometrical correlation of the valence quarks.

Abstract

We have studied the reactionspp?ppp+p-,K+p?K+pp+p-p, p+p? p+,pp+p- and p-p ?p+p- at 147 GeV/c using the 30-inch Fermilab hybrid system. All four reactions were detected with the same apparatus and analyzed in the same way. The energy dependence of the channel cross section was found to beAp-0.6+B for thepp reaction andAp-1+B for the other three. About 90% of the cross section at 147 GeV/c can be accounted for by either beam or target diffraction. Some of the remaining cross section may come from double Pomeron exchange reactions which we tried to isolate. We have tested the hypothesis of a factorizable Pomeron and our data indicates a violation of this hypothesis. We show that the 3p mass enhancement in the mass region 1.2–1.4 GeV is diffractively produced in the p± beam reactions. Fourprong, four-constraint and six-prong, four-constraint cross sections are reported.

Abstract

The gross features of the data are reviewed and the momentum tensor components, , and are studied. Evidence for coplanarity effects is observed. A probabilistic method to search for jets is proposed. The jets found by this method are seen to be similar to highpT jets frompp interactionse+e- annihilations andvp interactions. The effect of subtracting the leading particles and the effect of lowpT diffractive and non diffractive components are investigated.

Abstract

Distributions with respect toz andzR for the fastest and second fastest particles produced in both beam and target hemispheres from 147 GeV/c p- interactions are compared with each other and with the distributions for the fastest and second fastest particles from deepinelastic leptoproduction and Field-Feynman curves. The distributions and curves for the fastest particles are very similar, with the exception of the identified protons. Those for the second fastest are in agreement. Distributions with respect toz'R for the first through fourth fastest particles (excepting the protons) are all similar, suggesting that the shape of the distributions may be determined by the available longitudinal phase space.

Abstract

Work-related asthma is asthma that is caused or exacerbated by exposures at work. It is the most common form of occupational lung disease in developed countries. It has important impacts on the health and well-being of the affected individual, as well as consequences for society because of unemployment issues and workers' compensation claims. With ongoing exposure, occupational asthma can result in persistent airway hyperresponsiveness and, possibly, permanent disability for the individual. Thus, it is important for the clinician to be able to diagnose this disorder as quickly and accurately as possible. The evaluation of a patient with work-related asthma can be extensive. It includes obtaining a consistent history, identifying the cause in the workplace, and confirming the diagnosis with objective tests. After a diagnosis has been made, treatment must sometimes go beyond the medications used for nonoccupational asthma and include interventions to minimize or completely remove the individual from exposure to the causal agent if he or she has sensitizer-induced occupational asthma. In addition, once an individual has been identified with occupational asthma, steps should be taken to prevent the development of this disorder in other workers. The purpose of this article is to review the current literature and provide the clinician with a stepwise approach to the diagnosis and management of a patient with work-related asthma.

Abstract

The plastic response of a sheet metal is governed by the collective response of the underlying grains. Intragranular plasticity depends on intrinsic variables such as crystallographic orientation and on extrinsic variables such as grain interactions; however, the role of the latter is not well understood. A finite element crystal plasticity formulation is used to investigate the importance of grain interactions on intragranular plastic deformation in initially untextured polycrystalline aggregates. A statistical analysis reveals that grain interactions are of equal (or more) importance for determining the average intragranular deviations from the applied strain as compared to the orientation of the grain itself. Furthermore, the influence of the surrounding grains is found to extend past nearest neighbor interactions. It is concluded that the stochastic nature of the mesoscale environment must be considered for a proper understanding of the plastic response of sheet metals at the grain-scale.

Abstract

Several plant lineages have evolved adaptations that allow survival in extreme and harsh environments including many families within the plant clade Portulacineae (Caryophyllales) such as the Cactaceae, Didiereaceae, and Montiaceae. Here, using newly generated transcriptomic data, we reconstructed the phylogeny of Portulacineae and examined potential correlates between molecular evolution and adaptation to harsh environments. Our phylogenetic results were largely congruent with previous analyses, but we identified several early diverging nodes characterized by extensive gene tree conflict. For particularly contentious nodes, we present detailed information about the phylogenetic signal for alternative relationships. We also analyzed the frequency of gene duplications, confirmed previously identified whole genome duplications (WGD), and proposed a previously unidentified WGD event within the Didiereaceae. We found that the WGD events were typically associated with shifts in climatic niche but did not find a direct association with WGDs and diversification rate shifts. Diversification shifts occurred within the Portulacaceae, Cactaceae, and Anacampserotaceae, and whereas these did not experience WGDs, the Cactaceae experienced extensive gene duplications. We examined gene family expansion and molecular evolutionary patterns with a focus on genes associated with environmental stress responses and found evidence for significant gene family expansion in genes with stress adaptation and clades found in extreme environments. These results provide important directions for further and deeper examination of the potential links between molecular evolutionary patterns and adaptation to harsh environments.

Abstract

Posterior shoulder tightness is a problem in many patients with shoulder pain. Tightness manifests as decreased range of motion (ROM) caused by loss of posterior capsule or posterior shoulder muscle flexibility. The posterior capsule often loses flexibility in throwing athletes and may also be present in patients with impingement symptoms. A valid and reliable measurement of posterior capsule tightness is critical to making informed decisions about interventions to improve capsule flexibility. Low Flexion (LF) is a new test shown to be valid for assessing change in posterior capsule flexibility. This report describes three independent projects used to evaluate validity and reliability of LF to determine its clinical usefulness. In Study 1, overhead athletes (n = 13) were compared to non-overhead athletes (n = 13) to examine content validity, and in Study 2 pitchers (n = 18) were measured before and after throwing to assess the stability of LF. T-tests were used to compare mean LF in both analyses. In Study 3 patients receiving rehabilitation (n = 25) were measured twice bilaterally by a single rater to estimate overall reliability and reliability in those with shoulder pain (n = 19) using ICC(3,1) and standard error of measurement (SEM). The overhead athletes had dominant arm deficits in LF that were statistically different than the non-overhead athletes, but LF was not significantly different after throwing. Intraclass correlation coefficients (ICCs) were all above 0.90 and SEM below 3.0°. The Low Flexion test is shown to have acceptable content validity and excellent intra-rater reliability and can be used clinically by one rater to assess posterior capsule tightness., (Copyright © 2015 Elsevier Ltd.

Abstract

We report a case in which an active fixation atrial lead tip became entwined on the proximal lead body during implantation. It was not possible to disengage the tip or to remove the resultant lead loop atraumatically through the insertion site. Removal of the lead was accomplished using a Dotter intravascular snare inserted via a femoral vein, with subsequent successful implantation of a new lead. This unusual technique-related complication emphasizes the need for meticulous fluoroscopic visualization during lead manipulation.
