title: The meaning of well-being for undergraduate medical students: perspectives from Indonesia
Creators: name: Samosir, Andre Somba Gugun
Publisher: name: University of Glasgow
Year: 2023

description: A paucity in the literature concerning the well-being of the medical student population in Indonesia was identified, while there has been a rapid change in the landscape of Indonesian medical education and socioeconomic circumstances. The purpose of the study was to gain an understanding of the well-being of Indonesian medical students with a focus on the student themselves. Well-being is important for the students’ academic achievements and their flourishing throughout their lives. Specifically, the well-being of Indonesian medical students is explored using semistructured interviews of 46 third and fourth-year undergraduate students in 10 medical schools, acquired by means of purposive and snowball sampling methods. After Giorgian descriptive phenomenological analysis of the data, an essence of what is being well for the students emerged: it is being fulfilled, enabled, and grateful. There are many contributors that influence both the students’ well-being as well as its dynamics. The students acquire a sense of growth as a person throughout medical school, but descriptions of well-being related interventions in medical schools were sparse. On the whole, the findings, including the students’ expectations and challenges concerning their well-being, agreed with previous studies in the area and adequately answered the research questions. Recommendations for future research were presented alongside ways to ensure credibility and transferability, which include discussion on reflexivity and study limitations.
Roles of Antiferromagnetic Fluctuation in High Field Phase Diagram of Superconductors with Strong Paramagnetic Depairing
Creators: name: Ikeda, Ryusuke

Year: 2010
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: The high field phase diagram and magnetic properties of CeCoIn_5 below H_c2(0) are examined from the picture regarding the high field and low temperature (HFLT) phase as a possible Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) vortex lattice. Crucial roles of antiferromagnetic (AFM) fluctuations enhanced close to H_c2(0) are stressed. The FFLO vortex lattice with a longitudinal modulation parallel to the field is stabilized compared with those with lateral modulations as a consequence of the presence of AFM fluctuations. Further, an unusual field-induced enhancement of the flux distribution is argued to be a consequence of interplay between the paramagnetic depairing and AFM fluctuation, both of which are enhanced with increasing field.

description: We describe methods used to validate data from the Y.T. Lee Array for Microwave Background Anisotropy (AMiBA), an interferometric array designed to measure the Sunyaev-Zel'dovich effect and the anisotropy of the Cosmic Microwave Background (CMB). We perform several statistical tests on data from pointed galaxy cluster observations taken in 2007 and noise data from long-term blank sky observations and measurements with the feeds covered by the absorbers. We apply power spectrum analysis, cross power spectrum analysis among different outputs with different time lags in our analog correlator, and sample variance law tests to noise data. We find that (1) there is no time variation of electronic offsets on the time scale of our two-patch observations (~10 minutes); (2) noise is correlated by less than 10% between different lags; and (3) the variance of noise scales with the inverse of time. To test the Gaussianity of the data, we apply Kolmogorov-Smirnov (K-S) tests to cluster data, and find that a 5% significance level efficiently detects data sets with known hardware problems without rejecting an excess of acceptable data. We also calculate third- and fourth-order moments and cumulants for the noise residual visibilities and find that about 95% of our data are within the 99% confidence regions of Gaussianity.

Radiative and leptonic decays of the pseudoscalar charmonium state $η_c$
Creators: name: Yang, Mao-Zhi
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The radiative and leptonic decays of $η_c\to γγ$ and $η_c\to l^+l^-$ are studied. For $η_c\to γγ$ decay, the second-order electromagnetic tree-level diagram gives the leading contribution. The decay rate of $η_c\to γγ$ is calculated, the prediction is in good agreement with the experimental data. For $η_c\to l^+ł^-$, both the tree and loop diagrams are calculated. The analysis shows that the loop contribution dominates, the contribution of tree diagram with $Z^0$ intermediate state can only modifies the decay rate by less than 1%. The prediction of the branching ratios of $η_c\to e^+e^-$ and $μ^+μ^-$ are very tiny within the standard model. The smallness of these predictions within the standard model makes the leptonic decays of $η_c$ sensitive to physics beyond the standard model. Measurement of the leptonic decay may give information of new physics.

Spatial chaos of an extensible conducting rod in a uniform magnetic field

description: The equilibrium equations for the isotropic Kirchhoff rod are known to form an integrable system. It is also known that the effects of extensibility and shearability of the rod do not break the integrable structure. Nor, as we have shown in a previous paper does the effect of a magnetic field on a conducting rod. Here we show, by means of Mel'nikov analysis, that, remarkably, the combined effects do destroy integrability; that is, the governing equations for an extensible current-carrying rod in a uniform magnetic field are nonintegrable. This result has implications for possible configurations of electrodynamic space tethers and may be relevant for electromechanical devices.

Transcending slowness in Beethoven's late style

description: A central aspect of Beethoven’s late works, both in the scholarly literature and in recorded musical practice of the twentieth and twenty-first centuries, is the extreme slowness of the adagio sections. This has become such an ingrained part of musical culture that even the rise of the historically informed performance movement since the 1980s, which profoundly affected the tempos of slow music in a wide variety of repertoire, had little effect on the slow movements of Beethoven’s late style. Scholarship has generally attributed the slowness in the late works to the composer, but this chapter argues that the evidence for this is circumstantial and selectively chosen. It furthermore shows that these extremely slow speeds are instead the product of the reception history of this repertoire, and explores the erroneous transmission of the historical evidence involved, as well as the changing role of the concept of deafness in relation to this repertoire. Finally, it concludes that notwithstanding the oft-repeated claims of revisionism by scholars and musicians, the nineteenth-century 'cult of the classical adagio' continues, albeit tacitly, to shape our conception of Beethoven’s late style. Ein zentrales Thema der späten Werke Beethovens, sowohl in der wissenschaftlichen Literatur als auch in der musikalischen Praxis des 20. und 21. Jahrhunderts, ist das extrem langsame Tempo der Adagio-Abschnitte. Sie ist zu einem so tief verwurzelten Teil der Musikkultur geworden, dass selbst das Aufkommen der historisch informierten Aufführungsbewegung seit den 1980er Jahren, die die Tempi der langsamen Musik in einer Vielzahl von Repertoires tiefgreifend beeinflusst hat, kaum Auswirkungen auf die langsamen Sätze von Beethovens Spätwerk hatte. Die Wissenschaft hält die Authentizität dieser langsamen Tempi im Allgemeinen für verbürgt, aber dieses Kapitel zeigt, dass die Belege dafür recht zufällig und selektiv ausgewählt sind. Darüber hinaus wird gezeigt, dass diese extrem langsamen Tempi vielmehr ein Produkt der Rezeptionsgeschichte dieses Repertoires sind, und es wird der problematische Umgang mit den historischen Quellen sowie die sich verändernde Sicht auf Beethovens Taubheit in Bezug auf dieses Repertoire untersucht. Schließlich kommt der Aufsatz zu dem Schluss, dass der "Kult des klassischen Adagios" des 19. Jahrhunderts – ungeachtet der oft geäußerten Forderung von Wissenschaftlern und Musikern nach Revision dieses Konzepts – unseren Begriff des Beethovenschen Spätwerks weiterhin prägt, wenn auch stillschweigend.
Epimorphisms and Boundary Slopes of 2-Bridge Knots

description: In this article we study a partial ordering on knots in the 3-sphere where K_1 is greater than or equal to K_2 if there is an epimorphism from the knot group of K_1 onto the knot group of K_2 which preserves peripheral structure. If K_1 is a 2-bridge knot and K_1 > K_2, then it is known that K_2 must also be 2-bridge. Furthermore, Ohtsuki, Riley, and Sakuma give a construction which, for a given 2-bridge knot K_{p/q}, produces infinitely 2-bridge knots K_{p'/q'} with K_{p'/q'}>K_{p/q}. After characterizing all 2-bridge knots with 4 or less distinct boundary slopes, we use this to prove that in any such pair, K_{p'/q'} is either a torus knot or has 5 or more distinct boundary slopes. We also prove that 2-bridge knots with exactly 3 distinct boundary slopes are minimal with respect to the partial ordering. This result provides some evidence for the conjecture that all pairs of 2-bridge knots with K_{p'/q'}>K_{p/q} arise from the Ohtsuki-Riley-Sakuma construction.

The Determination Of Reddening From Intrinsic VR Colors Of RR Lyrae Stars

description: New R-band observations of 21 local field RR Lyrae variable stars are used to explore the reliability of minimum light (V-R) colors as a tool for measuring interstellar reddening. For each star, R-band intensity mean magnitudes and light amplitudes are presented. Corresponding V-band light curves from the literature are supplemented with the new photometry, and (V-R) colors at minimum light are determined for a subset of these stars as well as for other stars in the literature. Two different definitions of minimum light color are examined, one which uses a Fourier decomposition to the V and R light curves to find (V-R) at minimum V-band light, (V-R)_{min}^F, and the other which uses the average color between the phase interval 0.5-0.8, (V-R)_{min}^{ϕ(0.5-0.8)}. From 31 stars with a wide range of metallicities and pulsation periods, the mean dereddened RR Lyrae color at minimum light is (V-R)_{min,0}^F = 0.28 pm 0.02 mag and (V-R)_{min,0}^{ϕ(0.5-0.8)} = 0.27 pm 0.02 mag. As was found by Guldenschuh et al. (2005) using (V-I) colors, any dependence of the star's minimum light color on metallicity or pulsation amplitude is too weak to be formally detected. We find that the intrinsic (V-R) of Galactic bulge RR Lyrae stars are similar to those found by their local counterparts and hence that Bulge RR0 Lyrae stars do not have anomalous colors as compared to the local RR Lyrae stars.

description: The analysis of modern cosmological data is becoming an increasingly important task as the amount of data multiplies. An important goal is to extract geometric information, i.e. the metric of the cosmos, from observational data. The observer metric is adapted to the reality of observations: information received along the past null cone, and matter flowing along timelike lines. It provides a potentially very good candidate for a developing general numerical data reduction program. As a basis for this, we elucidate the spherically symmetric solution, for which there is to date single presentation that is complete and correct. With future numerical implementation in mind, we give a clear presentation of the mathematical solution in terms of 4 arbitrary functions, the solution algorithm given observational data on the past null cone, and we argue that the evolution from one null cone to the next necessarily involves integrating down each null cone.

description: There is a fundamental difference between the classical expression for the retarded electromagnetic potential and the corresponding retarded solution of the wave equation that governs the electromagnetic field. While the boundary contribution to the retarded solution for the {\em potential} can always be rendered equal to zero by means of a gauge transformation that preserves the Lorenz condition, the boundary contribution to the retarded solution of the wave equation governing the {\em field} may be neglected only if it diminishes with distance faster than the contribution of the source density in the far zone. In the case of a source whose distribution pattern both rotates and travels faster than light {\em in vacuo}, as realized in recent experiments, the boundary term in the retarded solution governing the field is by a factor of the order of $R^{1/2}$ {\em larger} than the source term of this solution in the limit that the distance $R$ of the boundary from the source tends to infinity. This result is consistent with the prediction of the retarded potential that part of the radiation field generated by a rotating superluminal source decays as $R^{-1/2}$, instead of $R^{-1}$, a prediction that is confirmed experimentally. More importantly, it pinpoints the reason why an argument based on a solution of the wave equation governing the field in which the boundary term is neglected (such as appears in the published literature) misses the nonspherical decay of the field.

description: The Ca triplet (CaT) feature in the near-infrared has been employed as a metallicity indicator for individual stars as well as integrated light of Galactic globular clusters (GCs) and galaxies with varying degrees of success, and sometimes puzzling results. Using the DEIMOS multi-object spectrograph on Keck we obtain a sample of 144 integrated light spectra of GCs around the brightest group galaxy NGC 1407 to test whether the CaT index can be used as a metallicity indicator for extragalactic GCs. Different sets of single stellar population models make different predictions for the behavior of the CaT as a function of metallicity. In this work, the metallicities of the GCs around NGC 1407 are obtained from CaT index values using an empirical conversion. The measured CaT/metallicity distributions show unexpected features, the most remarkable being that the brightest red and blue GCs have similar CaT values despite their large difference in mean color. Suggested explanations for this behavior in the NGC 1407 GC system are: 1) the CaT may be affected by a population of hot blue stars, 2) the CaT may saturate earlier than predicted by the models, and/or 3) color may not trace metallicity linearly. Until these possibilities are understood, the use of the CaT as a metallicity indicator for the integrated spectra of extragalactic GCs will remain problematic.

Diagchamp: a methodology for on-farm diagnostic assessment
Creators: name: Marguerie, Mathieu
Publisher: name: Zenodo

Subjects: SolACEPA

description: Problem: Many agronomic experiments, such as those carried out in the SolACE Project, are designed to vary a single factor, with all other conditions being equal. This can be limiting in what can be measured in one experiment, at one time. Opposingly, an agroecological approach is based on using and measuring several factors in the same field, adapted to various pedoclimatic conditions and objectives. This is also a limitation, as pedoclimates can often vary across short distances on-farm, at different times during the year. Solution: The “Diagchamp method” is a diagnostic, holistic approach to identify and hierarchize the limiting factors of final crop yield directly in the farmer’s fields by comparing crop growth to a climatic potential. The user of this method can compare results from agronomic experiments against agronomic diagnoses. Retrieving an agronomic diagnosis is done by choosing a sample field (Figure 1) and assessing multiple agronomic factors (Figure 2). This creates a baseline that suggests what the potential output of the field could be, based on the field data taken previously, which can then be compared with the actual production yields.

description: We report on a detection of an early rising phase of optical afterglow (OA) of a long GRB 090726. We resolve a complicated profile of the optical light curve. We also investigate the relation of the optical and X-ray emission of this event. We make use of the optical photometry of this OA obtained by the 0.5 m telescope of AI AS CR, supplemented by the data obtained by other observers, and the X-ray Swift/XRT data. The optical emission peaked at ~ 17.5 mag (R) at t-T0 ~ 500 s. We find a complex profile of the light curve during the early phase of this OA: an approximately power-law rise, a rapid transition to a plateau, a weak flare superimposed on the center of this plateau, and a slowly steepening early decline followed by a power-law decay. We discuss several possibilities to explain the short flare on the flat top of the optical light curve at t-T0 ~ 500 s; activity of the central engine is favored although reverse shock cannot be ruled out. We show that power-law outflow with Theta_obs/Theta_c > 2.5 is the best case for OA of GRB 090726. The initial Lorentz factor is Gamma_0 ~ 230-530 in case of propagation of the blast wave in a homogeneous medium, while propagation of this wave in a wind environment gives Gamma_0 ~ 80-300. The value of Gamma_0 in GRB 090726 thus falls into the lower half of the range observed in GRBs and it may even lie on the lower end. We also show that both the optical and X-ray emission decayed simultaneously and that the spectral profile from X-ray to the optical band did not vary. This OA belongs to the least luminous ones in the phase of its power-law decay corresponding to that observed for the ensemble of OAs of long GRBs.
