Theoretical and computational study of the energy dependence of the muon transfer rate from hydrogen to higher-Z gases

The recent PSI Lamb shift experiment and the controversy about proton size revived the interest in measuring the hyperfine splitting in muonic hydrogen as an alternative possibility for comparing ordinary and muonic hydrogen spectroscopy data on proton electromagnetic structure. This measurement critically depends on the energy dependence of the muon transfer rate to heavier gases in the epithermal range. The available data provide only qualitative information, and the theoretical predictions have not been verified. We propose a new method by measurements of the transfer rate in thermalized target at different temperatures, estimate its accuracy and investigate the optimal experimental conditions

An Examination of Two Contemporary Techniques in Five Works for Solo Bassoon: Descriptions and Performance Suggestions.

Much of the literature for solo bassoon of the past few decades is partially dependent upon the player\u27s ability to use contemporary techniques. While it is atypical for an entire composition to rely on such devices, a significant volume of recent solo literature may be unplayable to those who have not mastered them. My aim is to help solo bassoonists in perfecting two specific contemporary techniques: fluttertongue and singing while playing. Though quite standard for other woodwind instruments such as the flute, these techniques have not been adequately described for bassoonists. The repertoire chosen for this project represents works for solo bassoon that employ both fluttertongue and singing while playing. The pieces chosen for study demonstrate variety in notational representation, range of application and approach and departure from instances of these techniques. As a performer and advocate of contemporary bassoon works, I feel that a clear and approachable method for these techniques would encourage performers to program more contemporary music and offer composers the opportunity to have relevant pieces performed rather than avoided

Low-energy negative muon interaction with matter

Using simulated data, obtained with the FLUKA code, we derive empirical regularities about the propagation and stopping of low-energy negative muons in hydrogen and selected solid materials. The results are intended to help the preliminary stages of the set-up design for experimental studies of muon capture and muonic atom spectroscopy. Provided are approximate expressions for the parameters of the the momentum, spatial and angular distribution of the propagating muons. In comparison with the available data on the stopping power and range of muons (with which they agree in the considered energy range) these results have the advantage to also describe the statistical spread of the muon characteristics of interest.Comment: 17 pages, 9 figures; Version accepted for publication in JINS

Understanding Progress Toward Degree Completion for Student Veterans in the Post 9-11 Era: A Focused Life History Narrative

Veterans have long-succeeded in higher education, but because available data on contemporary student veteran success has been difficult to uncover, some question the success of this reemerging student population. While data is emerging that suggest student veterans are succeeding in higher education, this study sought to reveal factors that contributed to the success of graduating student veterans in the hopes that these factors can be nurtured in current and future generations of student veterans to help ensure their success as students. Using a new method, the focused life-history narrative, and a conceptual model grounded in nontraditional student theory and Astin’s IEO Model, this study suggests that success influencers emerge during the education of veterans, primarily from faculty and staff, but also from peer veterans, that serve to validate the decision to go to college by veterans and thus propels veterans forward to success. Other findings suggest that timely and accurate processing of education benefits serves to improve focus on the academic experience, rather than worrying about tuition and fee payments, enhancing success. Finally, this study suggests that structure and discipline are important to the successful degree attainment of veterans

Sea level rise scenarios in a changing climate. Learning from the past to predict the future

Geological investigations of Holocene (last 12 ka) sea-level stands represent a crucial contribution to quantify any possible post-industrial (i.e., last 150 years) acceleration in sea-level rise and provide new constrains into the effects of on-going global change on the coastal areas. In particular, definition of both the pattern and the magnitude of the land vertical motions is controlled by the isostatic adjustment along the global coastlines. We present here the results of a number of recent studies that were carried out along the coast of north and south America and of the Mediterranean Sea. These data allowed quantifying the recent acceleration in sea-level rise and to define future scenarios of coastal inundation along the global coastlines

Measuring the muonic H ground state hyperfine splitting with FAMU

The FAMU experiment will measure the hyperfine splitting in the ground state of muonic hydrogen \u394Ehfs(\u3bc 12 p)1s with a precision \u3b4\u3bb/\u3bb < 10 125 providing rZ, the Zemach radius of the proton with higher precision, than what was previously possible, disentangling discordant theoretical values. The aim is to set a cornerstone result about not yet explained anomalies on the charge radius rch of the proton. The Zemach radius rZ and the charge radius rch are the only proton shape-related values that can be directly extracted from experimental data, and rZ is the only one that gives information about the proton\u2019s magnetic dipole moment distribution. The status of the experiment is presented
