Un fantastique instrumental ? La harpe dans la musique d’inspiration fantastique d’André Caplet et d’Henriette Renié
Authors: Luzzati Constance
Published: October 2024

Le présent article questionne la pertinence de la catégorie esthétique du fantastique pour qualifier la musique instrumentale du début du xxe siècle, en concentrant ces interrogations sur le répertoire pour harpe, en particulier celui composé par André Caplet (1878-1925) et Henriette Renié (1875-1956). Un nouveau répertoire soliste et de chambre pour la harpe apparaît en France au tournant du siècle, au sein duquel l’inspiration littéraire fantastique occupe une place significative. Les titres affichent clairement le substrat littéraire fantastique ou merveilleux sur lequel ces oeuvres prennent appui : Conte fantastique (1923) de Caplet d’après Le Masque de la mort rouge d’Edgar A. Poe, Légende d’après Les Elfes de Leconte de Lisle (1904), Danse des lutins (1911) et Ballade fantastique (1913) d’après la nouvelle Le Coeur révélateur de Poe. L’article fait l’hypothèse que le fantastique est l’élément déclencheur qui pousse les auteurs de ces oeuvres à faire sonner la harpe d’une manière novatrice, renouvelant ainsi et sous un angle singulier l’écriture traditionnelle de l’instrument. L’étude du caractère fantastique des textes qui les ont inspirées, puis de l’écriture instrumentale propre à ces oeuvres permet de poser la question de l’existence d’un style fantastique purement instrumental.
Pilot Study on the Effects of Music-making on Cortisol, Alpha-amylase and Immunoglobulin-a Among Older Amateur Musicians
Authors: Barbeau Audrey-Kristel
Published: October 2024

There are many benefits associated with playing music in later life but few studies have looked at biomarkers of stress and immune response among musicians. A pilot study, undertaken to test a research protocol prior to a larger study, was carried out with eight amateur instrumentalists aged 50+ to investigate variations in stress (cortisol and alpha-amylase) and immune response (secretory immunoglobulin A) under two conditions (Music and Rest). In summary, cortisol levels tend to decline following both conditions, but results were more pronounced for the Rest condition. While sIgA increased in the Rest condition, it showed a larger variability in the Music condition. These results are promising and demonstrate that music can influence some biological markers. This study contributes to raising awareness that music can be a creative strategy to promote healthy aging.
Musicians’ Health and Wellness Resources in Canadian Post-Secondary Music
Programs
Authors: Tinoco Carlos , Traube Caroline , Guptill Christine
Published: October 2024

Research suggests that more than 80% of professional musicians will encounter
performance-related health conditions that negatively affect their ability to work. Current
literature suggests that these conditions are prevalent amongst post-secondary music
students. Existing studies examine a small number of post-secondary music schools who have
implemented health promotion courses in their curricula and have demonstrated improvements
in self-efficacy and perceived knowledge of health promotion strategies. We sought to
examine health promotion and health education offerings in Canadian post-secondary music
programs. Members of the new Canadian Network for Musicians’ Health and Wellness (cnmhw) were the focus of this study. Members completed a survey and
were then interviewed to further discuss their educational offerings. All the post-
secondary institutions examined have health education offerings available to students. Four
institutions have courses implemented within their curricula; the other institution has a
sizeable selection of health-related initiatives available to students.

Terahertz metasurface functional devices as an effective method to control terahertz waves have attracted extensive attention from researchers. In order to enhance the functionality and flexibility of the metasurface and adapt to diverse application scenarios and demands, a beam-steering controllable reflective metasurface is designed by combining the Pancharatnam-Berry phase principle and the phase change material vanadium dioxide in this work. The metasurface unit consists of five layers, they being the top layer that is a metal patterned layer, the third layer that is made of vanadium dioxide and located between the dielectric layers with different thickness, the dielectric layer that is made of polytetrafluoroethylene (PTFE), and the bottom layer that serves as a metal reflective layer. The metasurface units are rotated based on the Pancharatnam-Berry phase principle to obtain four metasurface units with fixed phase differences in between, after which the metasurface units are arranged in two dimensions based on the generalized Snell reflection law to obtain the desired phase-gradient deflected reflection beam. The insulating state-metallic state transition of the vanadium dioxide layer on the metasurface can change the phase gradient of the preset metasurface, thereby realizing the on/off function of deflection. The simulation results show that when the vanadium dioxide is in the insulating state, the phase gradient of the designed metasurface appears, and the metasurface can deflect the vertically incident circularly polarized wave with specific angle anomalies in a operating band of 1.1–2.0 THz; when the vanadium dioxide is in the metallic state, for the same operating band of the same metasurface, the phase gradient of the metasurface disappears, and the metasurface mirror reflects the vertically incident circularly polarized waves, thereby realizing the function switching. This design provides new possibilities for modulating the terahertz reflected beam, which will have potential applications in terahertz wireless communication and radar systems.

Integrated quantum memories based on micro-/-nano structures, such as waveguides, can significantly enhance the scalability and reduce the consumption of optical and electrical power. 151Eu3+:Y2SiO5 stands out as an exceptional candidate material for quantum memory, because it possesses a spin coherence lifetime of 6 h and an optical storage lifetime of 1 h. Here we employ focused ion beam technology to fabricate a triangular nanobeam on the surface of a Y2SiO5 crystal. The width and length of the nanobeam are 2 μm and 20 μm, respectively. The optical lifetime and inhomogeneous broadening of 151Eu3+ in the triangular nanobeam are measured by fluorescence spectroscopy. The optical lifetime is (1.9±0.1) ms and the optical inhomogeneous broadening is (1.58±0.05) GHz at a doping level of 0.07% for 151Eu3+. The hyperfine transition spectra are measured by using optically detected magnetic resonance and spin inhomogeneous broadening of (19±3) kHz is obtained. Furthermore, we analyze the coherence properties of optical and hyperfine transitions, respectively, via transient spectral hole burning and spin echo measurement. We obtain an optical homogeneous linewidth down to (22±3) kHz, which is still limited by the instantaneous spectral diffusion. The spin coherence lifetime under the geomagnetic field is (5.1±0.6) ms. The results demonstrate that 151Eu3+ ions embedded within the 2 μm triangular nanobeam essentially retain the same optical and hyperfine transition properties as those observed in bulk crystals. Consequently, this research lays a foundation for studying the integrated quantum memories based on 151Eu3+ ensembles and the detection of the single 151Eu3+ ion based on the focused ion beam technique.

The hysteresis model of giant magnetostrictive materials (GMMs) changes with model parameters: the excitation amplitude, bias condition and excitation frequency. The existing hysteresis model is unable to predict the effects of simultaneous changes in the three external conditions. In this paper, the hysteresis loss mechanism is explained by using the traditional Jiles-Atherton (J-A) dynamic model, and the relation equation is established according to the operating conditions and material properties to respond to the changes of external conditions. For the J-A model, the relationship equation related to the excitation amplitude is established, and the relationship equation relating the residual loss coefficient to the excitation amplitude and the bias condition is established for the residual loss, while the eddy current loss of the system is redefined by using the fractional order to obtain the modified hysteresis model. In the paper, the genetic algorithm is used to identify the model parameters of the test data under different operating conditions, and the corresponding correction coefficients are obtained according to the model parameters and the operating conditions. The accuracy of the modified model is verified by simulating the model and analyzing the influences of eddy currents and residual losses and their effects on the model predictions. The hysteresis model is evaluated to compare the hysteresis curves with the hysteresis losses in terms of errors. The results show that the modified model is capable of predicting various excitations with high accuracy, and that neglecting dynamic losses at low frequencies results in large errors. If the model order of the eddy current loss is smaller than the actual order of the material, the predicted hysteresis curve will be contracted inward and the predicted eddy current loss will be small; on the contrary, the predicted hysteresis curve will be expanded outward and the predicted eddy current loss will be large, and with the increase of the excitation frequency, both cases will cause the prediction error to become larger and larger. When the bias magnetic field is zero, the residual loss coefficient is unchanged; when the bias magnetic field is kept constant, the excitation amplitude increases and the residual loss coefficient decreases; when the excitation amplitude is unchanged, the bias magnetic field increases and the residual loss coefficient also increases. When both the bias magnetic field and the excitation amplitude change at the same time, it is necessary to conduct an actual analysis of their corresponding residual loss coefficients. Using hysteresis curves to evaluate hysteresis is more accurate.

Murine models are often used to study the pathogenicity and dissemination of the enteric pathogen Salmonella enterica serovar Typhimurium. Here, we quantified S. Typhimurium population dynamics in mice using the STAMPR analytic pipeline and a highly diverse S. Typhimurium barcoded library containing ~55,000 unique strains distinguishable by genomic barcodes by enumerating S. Typhimurium founding populations and deciphering routes of spread in mice. We found that a severe bottleneck allowed only one in a million cells from an oral inoculum to establish a niche in the intestine. Furthermore, we observed compartmentalization of pathogen populations throughout the intestine, with few barcodes shared between intestinal segments and feces. This severe bottleneck widened and compartmentalization was reduced after streptomycin treatment, suggesting the microbiota plays a key role in restricting the pathogen’s colonization and movement within the intestine. Additionally, there was minimal sharing between the intestine and extraintestinal organ populations, indicating dissemination to extraintestinal sites occurs rapidly, before substantial pathogen expansion in the intestine. Bypassing the intestinal bottleneck by inoculating mice via intravenous or intraperitoneal injection revealed that Salmonella re-enters the intestine after establishing niches in extraintestinal sites by at least two distinct pathways. One pathway results in a diverse intestinal population. The other re-seeding pathway is through the bile, where the pathogen is often clonal, leading to clonal intestinal populations and correlates with gallbladder pathology. Together, these findings deepen our understanding of Salmonella population dynamics.

Knowledge, attitude and purchasing behavior of Saudi mothers towards food additives and dietary pattern of preschool children
Authors: Almoabadi Reem H. , Hanbazaza Mahitab A.
Published: October 2024

Background

There are over 506 children’s products containing one or more types of additives. Maternal awareness of these additives is essential for the health of preschool-aged children, as this period is vital for children’s growth and development. This study aims to assess the knowledge, attitudes, and purchasing behaviors related to food additives among mothers living in the western region of Saudi Arabia, as well as the dietary patterns of preschool children.

Method

A cross-sectional study was conducted using an online survey with a convenience sample of 521 mothers of preschool-aged children (3–5 years old). The survey gathered data on the child’s age, number of children, the youngest child’s weight and height, food intolerance, tooth decay, as well as the dietary patterns of preschool children. It also assessed the mother’s knowledge, attitude, and purchasing behaviors related to food additives.

Results

The study found that 46.6% of mothers demonstrated good knowledge of food additives, while 56.0% demonstrated fair attitudes and 78.5% good purchasing behavior regarding additives. Additionally, the majority of mothers reported favorable dietary patterns for their preschool-aged children. “Biscuits and crackers” had the highest consumption frequency (4.98 ± 1.50), with 36.7% of children consuming them once daily, while “Soft beverages” had the lowest consumption frequency (2.73 ± 2.04), with 46.6% of children never consuming them. Statistically significant differences were identified between mothers’ knowledge and their age, education level, occupation status, and economic status (p < 0.05). ANOVA results also indicated a statistically significant difference between mothers’ attitudes and occupation status (p < 0.05). Furthermore, there were significant positive correlations between mothers’ knowledge of food additives and their attitudes (r = 0.293) and purchasing behaviors (r = 0.284) related to additives.

Conclusion

The findings suggest that mothers possess a relatively good level of knowledge of food additives and hold fair attitudes toward them, tending to result in healthier purchasing behaviors and dietary practices for their preschool-aged children. To increase awareness, nutrition intervention programs are required across various socio-economic groups of mothers in the western region of Saudi Arabia. These programs can significantly contribute to promoting healthier dietary practices for preschool-aged children and improving overall family health and well-being.

Amyloid beta (Aβ) deposition in the brain is regarded as an early toxic effect in the aetiopathogenesis of Alzheimer’s Disease (AD). Currently, Aβ is considered a key marker for AD and a promising target for drug development for the future management of debilitating diseases such as AD. However, the pathomechanism of Aβ has not yet been precisely understood in terms of AD patients, specifically regarding the pathological forms of Aβ and how it associates with other biochemical markers to cause dementia. Identifying Aβ as a key hallmark, especially at the earliest stages of the disease, is essential for understanding the progression of AD and its applicability for the development of novel therapeutics aimed at managing cognitive impairment and AD. This review aims to explain the neurotoxicity of Aβ and its correlation with various other biological markers that contribute to the induction of AD and memory deterioration.
