The story of the Soni Ventorum Wind Quintet
No full textThesis (D. Mus. Arts)--University of Washington, 2000The Soni Ventorum Wind Quintet has been the wind quintet-in-residence at the University of Washington School of Music since 1968. Officially founded in 1962, when its members were on the faculty of the Conservatory of Music of Puerto Rico, the group has had a long and stable history. Through their concerts, tours, and recordings, the Soni Ventorum Wind Quintet has established an international reputation. Over the years, many distinguished composers have written works especially for the Soni Ventorum, thus expanding the repertoire of the wind quintet.This study traces the history of the Soni Ventorum Wind Quintet mainly through interviews with the quintet members themselves. This history includes antecedent quintets in which members of the Soni Ventorum Wind Quintet participated (namely, a student quintet at the Curtis Institute, The American Wind Ensemble of Vienna, and the U.S. Seventh Army Symphony Wind Quintet). It covers the founding of the Soni Ventorum Wind Quintet in 1962 at the Conservatory of Music in Puerto Rico through their tenure from 1968 through the present as the wind quintet-in-residence at the University of Washington in Seattle. It gives an account of the establishment of the Soni Ventorum's recording career, their approach to sound and ensemble, their many tours, participation in festivals and competitions, and personnel. The study details the Soni Ventorum's collaborations with colleagues at the University of Washington School of Music, especially the many composers who wrote pieces for the group. One chapter covers ensemble pieces that have been written for the members of the Son! Ventorum Wind Quintet, while another presents wind quintet and quartet arrangements that were prepared by the quintet members themselves. The final chapter provides biographies of the members of the Soni Ventorum Wind Quintet.The Introduction to the study is a brief history of wind quintets. The study concludes with detailed appendices cataloguing the Soni Ventorum Wind Quintet's repertoire, concerts, residencies, tours and a complete discography.At the time of this writing, the author is aware of no other work detailing the history of an established wind quintet
Knowledge and Attitude towards Sports Injury Prevention and Management among Sports Playing College Students: A Cross-sectional Study
No full textIntroduction: Sports is an emerging field among young people and has gained popularity worldwide. Consequently, the prevalence of sports-related injuries has increased day by day. To address this issue, all types of studies have been conducted. However, the knowledge and attitude of athletes are considered two key factors in preventing sports injuries.
Aim: To determine the current status of knowledge and attitude regarding Sports Injury Prevention and Management (SIPM) among college students engaged in sports.
Materials and Methods: This cross-sectional study was conducted under the affiliation of the College of Physiotherapy, Sumandeep Vidyapeeth, in the Vadodara district, Gujarat, India, from June 2022 to May 2023. A total of 141 male and female participants were included. Demographic details, including gender, number of total practice days per week and prior sports injury experience, were collected. Participants who had experience in playing various outdoor sports were included. The investigator conducted interviews with the participants and the information was noted. The t-test was used for statistical analysis.
Results: The t-test was applied to the SIPM knowledge and attitude scales to analyse differences across demographic factors such as gender, total practice days per week and sports injury experience in the past year. The results showed no significant differences among subjects (t(141)=1.89, p-value>0.05). Pearson’s correlation analysis revealed that total knowledge scores and total attitude scores of SIPM among student athletes were positively correlated (r=0.3, p-value=0.003).
Conclusion: The study concluded a positive correlation between knowledge and attitude, indicating that higher levels of knowledge are associated with a more positive attitude towards prevention and management of sports injuries
PULSE-SMART: Pulse-Based Arrhythmia Discrimination Using a Novel Smartphone Application
No full textCo-author Apurv Soni is a medical student in the MD/PhD Program at UMass Medical School.BACKGROUND: Atrial fibrillation (AF) is a common and dangerous rhythm abnormality. Smartphones are increasingly used for mobile health applications by older patients at risk for AF and may be useful for AF screening. OBJECTIVES: To test whether an enhanced smartphone app for AF detection can discriminate between sinus rhythm (SR), AF, premature atrial contractions (PACs), and premature ventricular contractions (PVCs). METHODS: We analyzed two hundred and nineteen 2-minute pulse recordings from 121 participants with AF (n = 98), PACs (n = 15), or PVCs (n = 15) using an iPhone 4S. We obtained pulsatile time series recordings in 91 participants after successful cardioversion to sinus rhythm from preexisting AF. The PULSE-SMART app conducted pulse analysis using 3 methods (Root Mean Square of Successive RR Differences; Shannon Entropy; Poincare plot). We examined the sensitivity, specificity, and predictive accuracy of the app for AF, PAC, and PVC discrimination from sinus rhythm using the 12-lead EKG or 3-lead telemetry as the gold standard. We also administered a brief usability questionnaire to a subgroup (n = 65) of app users. RESULTS: The smartphone-based app demonstrated excellent sensitivity (0.970), specificity (0.935), and accuracy (0.951) for real-time identification of an irregular pulse during AF. The app also showed good accuracy for PAC (0.955) and PVC discrimination (0.960). The vast majority of surveyed app users (83%) reported that it was "useful" and "not complex" to use. CONCLUSION: A smartphone app can accurately discriminate pulse recordings during AF from sinus rhythm, PACs, and PVCs.MD/Ph
Observation of the suppressed ADS modes B± → [π±K-/+ π+π-]D K± and B± → [π± K-/+π+π-]Dπ±
No full textAn analysis of and B± → DK± and B± → Dπ±
decays is presented where the D meson is reconstructed in the four-body final state K± π-/+π+π-. Using LHCb data corresponding to an integrated luminosity of 1.0 fb-1, first observations are made of the suppressed ADS modes B± →[π± K-/+π+π-]DK± and B± → [π± K-/+π+π-]Dπ± with a significance of 5.1 sigma and greater than 10 sigma, respectively. Measurements of CP asymmetries and CP-conserving ratios of partial widths from this family of decays are also performed. The magnitude of the ratio between the suppressed and favoured B± → DK ± amplitudes is determined to be rKB = 0.097 ± 0.011
A study of CP violation in B±→DK±B±→DK± and B±→Dπ±B±→Dπ± decays with D→KS0K±π∓ final states
No full textA first study of CP violation in the decay modes B± → [K0S K ±π∓]Dh± and B± → [K0S K ∓π±]Dh±, where h labels a K or π meson and D labels a D0 or D0 meson, is performed. The analysis uses the LHCb data set collected in pp collisions, corresponding to an integrated luminosity of 3 fb−1. The analysis is sensitive to the CP-violating CKM phase γ through seven observables: one charge asymmetry in each of the four modes and three ratios of the charge-integrated yields. The results are consistent with measurements of γ using other decay modes
Measurement of the CKM angle gamma from a combination of B->Dh analyses
No full textA combination of three LHCb measurements of the CKM angle gamma is presented. The decays B->DK and B->Dpi are used, where D denotes an admixture of D0 and D0-bar mesons, decaying into K+K-, pi+pi-, K+-pi-+, K+-pi-+pi+-pi-+, KSpi+pi-, or KSK+K- final states. All measurements use a dataset corresponding to 1.0 fb-1 of integrated luminosity. Combining results from B->DK decays alone a best-fit value of gamma = 72.0 deg is found, and confidence intervals are set gamma in [56.4,86.7] deg at 68% CL, gamma in [42.6,99.6] deg at 95% CL. The best-fit value of gamma found from a combination of results from B->Dpi decays alone, is gamma = 18.9 deg, and the confidence intervals gamma in [7.4,99.2] deg or [167.9,176.4] deg at 68% CL, are set, without constraint at 95% CL. The combination of results from B->DK and B->Dpi decays gives a best-fit value of gamma = 72.6 deg and the confidence intervals gamma in [55.4,82.3] deg at 68% CL, gamma in [40.2,92.7] deg at 95% CL are set. All values are expressed modulo 180 deg, and are obtained taking into account the effect of D0-D0bar mixing
Measurement of the branching fractions for B--> D(*)+pi(-)l(-)(nu)over-bar(l) and (B)over-bar(0)-> D-(*)0 pi(+)l(-)(nu)over-bar(l)
No full textWe report on a measurement of the branching fractions for B- --> D(*)+ pi(-)l(-)(nu) over bar (l) and (B) over bar (0) --> D-(*)0 pi(+)l(-)(nu) over bar (l) with 275 x 10(6) B (B) over bar events collected at the Y(4S) resonance with the Belle detector at KEKB. Events are tagged by fully reconstructing one of the B mesons in hadronic modes. We obtain B(B- --> D(+)pi(-)l(-)(nu) over bar (l)) = (0.54 +/- 0.07 (stat) +/- 0.07(syst) +/- 0.06(BR)) x 10(-2), B(B- --> D*+pi(-) l(-) (nu) over bar (l)) (0.67 +/- 0.11 (stat) +/- 0.09(syst) +/- 0.03(BR)) x 10(-2), B((B) over bar (0) --> D(0)pi(+)l(-) (nu) over bar (l)) = (0.33 +/- 0.06(stat) +/- 0.06(syst) +/- 0.03(BR)) x 10(-2), B((B) over bar (0) -->D(*0)pi(+)l(-)(nu) over bar (l)) = (0.65 +/- 0.12(stat) +/- 0.08(syst) +/- 0.05(BR)) x 10(-2), where the third error comes from the error on (B) over bar --> D((*))l(-)(nu) over bar (l) decays. Contributions from B-0 --> D(*+)l(-)(nu) over bar (l) decays are excluded in the measurement of (B) over bar (0) --> D(0)pi(+)l-(nu) over bar (l).Astronomy & AstrophysicsPhysics, Particles & FieldsSCI(E)0ARTICLE5null7
System architecture induces document architecture
No full textThe documentation of an architecture is as important as the architecture itself. Tasked with communicating the structure and behaviour of a system and its constituent components to various stakeholders, the documentation is not trivial to produce. It becomes even harder in open, modular systems where components can be replaced and reused in each progressive build. How should documentation for such systems be produced and how can it be made to easily evolve along with the system it describes? We propose that there is a close mapping between the system architecture and its documentation. We describe a relational model for the architecture of open systems, paying close attention to the property that certain components can be reused or replaced. We then use ideas from storytelling and a discourse theory called Rhetorical Structure Theory (RST) to propose a narrative-based approach to architecture documentation; giving both a generic narrative template for component descriptions and a RST-based relational model for the document architecture. We show how the two models (system and documentation) map onto each other and use this mapping to demonstrate how document fragments can be stored, automatically extracted and collated to closely reflect the system’s architecture
Exploring Intertexuality in J.M. Coetzee's Disgrace
No full textM. Coetzee is a writer who lived and worked in South Africa under the apartheid rule until 1990. He used his works to unveil the transition in the political world. He has found a new way of creating the South African world, rejecting all conventional modes. A creative writing is always a rewriting which highlights the trace of various texts, sometimes consciously and often unknowingly. These texts can be historical, political, social or any other which advocates the idea of intertexuality. Therefore, every work is a reflection of the author's past experiences and readings. John Maxwell Coetzee has woven his novel ‘Disgrace' in the frame of intertexuality, where the English romantic movement had been projected in the context of politically changed South Africa. Creative works by any author are no longer seen as only his imaginative creation. All works are considered as the products of prior works in any field of knowledge. In the process of understanding any text, it is believed that our knowledge is structured and dynamic in nature. It is mainly derived from our concept of the world through the use of language which comprises all genres. Readers of the world are integrated into single world humanity. Similarly, all texts, whether literary or non-literary, are ‘intertextual'
Search for mixing using semileptonic decays at Belle
No full textA search for mixing in the neutral D meson system has been performed using semileptonic D^0 \to K^(*)- e^+ nu decays. Neutral D mesons from D^*+ \to D^0 pi+ decays are used; the flavor at production is tagged by the charge of the slow pion. The measurement is performed using 253 fb^-1 of data recorded by the Belle detector. From the yield of right-sign and wrong-sign decays arising from non-mixed and mixed events, respectively, we estimate the upper limit of the time-integrated mixing rate to be r_D < 1.0 x 10^-3 at 90 % C.L
