Neutral Pion Asymmetries at Intermediate Pseudorapidity in Transversely Polarized p + p Collisions at √ s = 200 GeV

Among the unanswered questions pertaining to nucleon spin physics is the origin of large azimuthal asymmetries (AN ) found in π forward pseudorapidity, η, from high-energy transversely polarized p + p collisions. One possible explanation is offered by twist-3 parton distribution and fragmentation functions. In order to test these and other mechanisms, it is important to study how the asymmetry changes over a range of pion kinematics. The STAR Endcap Electromagnetic Calorimeter (EEMC) is the only RHIC detector with the ability to study AN for π available at intermediate pseudorapidity, 0.8 ≤ η ≤ 2.0. STAR recently published the first measurement of AN for π using data collected in 2006 with collision energy √ STAR collected a high-statistics dataset with transverse beam polarization at √ s = 200 GeV. This offers over a five-fold increase in integrated luminosity relative to the 2006 dataset and a chance to enhance the precision of the previous results. The primary objective of this study is to determine the quality of the data from 2012 and to estimate the final statistical uncertainty.Preliminary results from this study indicate a significant improvement over the 2006 results

Electronic Patient-Physician Communication: Problems and Promise

A critical mass of Internet users will soon enable wide diffusion of electronic communication within medical practice. E-mail between physicians and patients offers important opportunities for better communication. Linking patients and physicians through e-mail may increase the involvement of patients in supervising and documenting their own health care, processes that may activate patients and contribute to improved health. These new linkages may have profound implications for the patientphysician relationship. Although the federal government proposes regulation of telemedicine technologies and medical software, communications technologies are evolving under less scrutiny. Unless these technologies are implemented with substantial forethought, they may disturb delicate balances in the patient-physician relationship, widen social disparities in health outcomes, and create barriers to access to health care. This paper seeks to identify the promise and pitfalls of electronic patient-pbysician communication before such technology becomes widely distributed. A research agenda is proposed that would provide data that are useful for careful shaping of the communications infrastructure. The paper addresses the need to 1) define appropriate use of the various modes of patient-physician communication, 2) ensure the security and confidentiality of patient information, 3) create user interfaces that guide patients in effective use of the technology, 4) proactively assess medicolegal liability, and 5) ensure access to the technology by a multicultural, multilingual population with varying degrees of literacy.History of Scienc

Renormalization of Boundary Fermions and World-Volume Potentials on D-branes

We consider a sigma model formulation of open string theory with boundary fermions carrying Chan-Paton charges at the string ends. This formalism is particularly suitable for studying world-volume potentials on D-branes. We perform explicit two-loop sigma model computations of the potential T-dual to the non-abelian Born-Infeld action. We also discuss the world-volume couplings of NS fluxes which are responsible for Myers' dielectric effect.Comment: 17 pages, 8 figure

Auditory lexical decisions in developmental language disorder:A meta-analysis of behavioural studies

Purpose: Despite the apparent primacy of syntactic deficits, children with developmental language disorder (DLD) often also evidence lexical impairments. In particular, it has been argued that this population have difficulty forming lexical representations that are detailed enough to support effective spoken word processing. In order to better understand this deficit, a meta-analysis of studies testing children with DLD in the auditory lexical decision task was conducted. The objective was to provide summary effect size estimates for accuracy and response time measures for comparisons to age- and language-matched control groups. Method: Two thousand three hundred seventy-two records were initially identified through electronic searches and expert consultation, with this cohort reduced to 9 through duplicate removal and the application of eligibility and quality criteria. The final study cohort included 499 children aged 3;8–11;4 (years;months). Results: Multivariate analysis suggests that children with DLD were significantly less accurate in the auditory lexical decision task than age-matched controls. For the response time estimate, however, confidence intervals for the same group comparison crossed 0, suggesting no reliable difference between groups. Confidence intervals also crossed 0 for language-matched control estimates for both accuracy and response time, suggesting no reliable difference between groups on either measure. Conclusion: Results broadly support the hypothesis that children with DLD have difficulty in forming detailed lexical representations relative to age- though not language-matched peers. However, further work is required to determine the performance profiles of potential subgroups and the impact of manipulating different lexical characteristics, such as the position and degree of nonword error, phonotactic probability, and semantic network size

On T-duality for open strings in general abelian and nonabelian gauge field backgrounds

We discuss T-duality for open strings in general background fields both in the functional integral formulation as well as in the language of canonical transformations. The Dirichlet boundary condition in the dual theory has to be treated as a constraint on the functional integration. Furthermore, we give meaning to the notion of matrix valued string end point position in the presence of nonabelian gauge field background.Comment: 10 pages, Latex, an inconsistency of the notation in section 3 is removed, 2 references adde

Nonabelian gauge field dynamics on matrix D-branes

We construct a calculational scheme for handling the matrix ordering problems connected with the appearance of D-brane positions taking values in the same Lie algebra as the nonabelian gauge field living on the D-brane. The formalism is based on the use of an one-dimensional auxiliary field living on the boundary of the string world sheet and taking care of the order of the matrix valued fields. The resulting system of equations of motion for both the gauge field and the D-brane position is derived in lowest order of the $\alpha'$ -expansion.Comment: 14 pages, Latex, 2 figures, including epsfig.sty, a wrong reference number correcte

Pennsylvania’s True Commonwealth: The State of Manufacturing – Challenges and Opportunities (Full Report)

The Industrial Resource Center Network of Pennsylvania is the state’s affiliate of the National Institute of Standards and Technology’s Hollings Manufacturing Extension Partnership program. Both the IRC program and the MEP have longstanding traditions of self-assessment and evolution as ways of being accountable to the public and of promoting continuous improvement. The IRC program and the MEP are charged with helping manufacturing in general, and small to midsized manufacturers in particular, improve their competitive position. The IRC program uses the outcomes from these assessments to think about the challenges their constituents face due to rapid evolution in the globally competitive environment. Additionally, the IRC Program has joined with the MEP to discover best management and production practices, standardize them in terms of educational and training practices, and then disseminate these practices widely. Again, this is with an emphasis on small and midsized establishments and businesses. This report builds on the 2004 report, Manufacturing Pennsylvania’s Future, written by Deloitte Consulting and the Maxine Goodman Levin College of Urban Affairs at Cleveland State University. In August 2010, as the negative impact of the Great Recession was beginning to ebb and after a decade of global competitive challenges, the IRC Program embarked on a new round of self-evaluation and assessment. The economic development and nonprofit management research groups at Cleveland State University’s Levin College were engaged to examine the state of manufacturing in the Commonwealth, discover the management practices of the “best of the best” manufacturers in the state, and suggest practice innovations that would enhance the competitive position of Pennsylvania’s manufacturers. This work was undertaken with the MPI Group. The project was supported by funding from the Industrial Resource Center program, the Hollings Manufacturing Extension Partnership of the National Institute of Standards and Technology, the John D.and Catherine T. MacArthur Foundation’s Network on Building Resilient Regions, and the Pennsylvania Department of Community and Economic Development, with funding provided by the National Telecommunications and Information Administration. The work benefited from the advice and review of an external advisory board that was facilitated by Ken Voytek, NIST/MEP’s chief economist, and Joe Houldin, CEO of the Delaware Valley Industrial Resource Center. They worked with: Emily DeRocco, President, the Manufacturing Institute of the National Association of Manufacturers; Samuel Leiken, Vice President of the Council on Competitiveness; Howard Wial, Ph.D., Fellow of the Metropolitan Policy Program of the Brookings Institution; and Mike Trebing, Senior Economic Analyst, Federal Reserve Bank of Philadelphia. The work was also reviewed and discussed by the IRC’s Strategic Advisory Board and the directors of the network\u27s seven centers. The report also benefited from data provided by the Central Pennsylvania Workforce Development Corporation (CPWDC). The research team acknowledges the many contributions of our advisers and funders.
