Published: January 2025

Abstract
Single-phase monoclinic Cu2SnS3 (CTS) thin films on Mo-coated soda-lime glass (SLG) substrates were fabricated through dual-source fine-channel mist chemical vapor deposition (CVD) by optimizing the deposition sequence and annealing process. The conventional deposition process using mist CVD caused Mo dissolution, thereby hindering CTS deposition on the Mo-coated SLG substrate. Therefore, to prevent Mo dissolution, a two-step deposition process was employed—initially, a Cu–Sn–S thin film was deposited briefly, followed by drying before the second deposition. This approach enabled deposition of CTS thin films on the Mo-coated SLG substrates. In addition to the fabrication of single-phase monoclinic CTS thin films, we attempted in situ annealing, annealing with flowing mist, and cover annealing, i.e. annealing while covering the deposited film with an SLG substrate in in an N2 atmosphere. After in situ and cover annealing processes, the Raman spectra showed only single-phase monoclinic CTS.
Terahertz wave generation via difference frequency mixing under nearly resonant exciton excitation with 1.5 μm band laser light in GaSb/AlGaSb multiple quantum wells

Published: January 2025

Abstract
Direct conversion of 1.5 μm band light to terahertz wave is significant for ultrafast telecommunication and safer spectroscopy. This study reports generating terahertz waves via difference frequency mixing by exciting strained semiconductor quantum wells with a 1.5 μm band laser emitting two wavelengths. The excitation power dependence demonstrates a clear square dependence of the intensity, and the well-width dependence suggests the possibility creating nonlinear polarization by localized excitons.

Published: January 2025

Abstract
Pre-stress affects the performance of piezoelectric micromechanical ultrasonic transducers (PMUTs), but the influence mechanism of pre-stress is not deeply discussed. This research examines the impact of pre-stress on PMUTs with different structures and sizes through simulations, theoretical calculations, and experiments. The findings reveal that pre-stress mainly influences PMUTs based on stiffness, with lower stiffness devices undergoing greater neutral axis shifts under stress. These shifts lead to notable changes in stiffness, resonance frequency, and electromechanical coupling coefficient. Under 45 MPa tensile stress, the stiffness change rate for clamped and pinned PMUTs is 12.16% and 57.42%, respectively, with pinned structures showing 2–3 times larger changes in frequency and coupling coefficient. Applying a DC bias of ±40 V to simulate pre-stress shows that pinned PMUT frequency deviations three times greater than clamped ones, with stiffness change rates of 61.08% and 9.87%, respectively. This study offers valuable insights for evaluating stress in industrial PMUT applications.
Polarity inversion of GaN from +c to −c polarity by metalorganic vapor phase epitaxy
Authors: Ikeda Kazuhisa , Uemukai Masahiro , Tanikawa Tomoyuki , Katayama Ryuji 
Published: January 2025

Abstract
GaN polarity inversion from Ga-polar (+c) to N-polar (−c) was demonstrated by combining multiple metalorganic vapor phase epitaxy (MOVPE) and surface oxidation and nitridation processes. Annealing the +c-GaN film at 900 °C caused surface roughening, and β-Ga₂O₃ was formed when the annealing time exceeded 240 min. Subsequent nitridation at 870 °C and GaN regrowth by MOVPE achieved −c-GaN growth on the +c-GaN film. Competition between +c-GaN regrowth and oxide film decomposition led to the formation of voids near the regrowth interface. We demonstrate a new potential for the epitaxial growth of –c-GaN films, enabling the utilization of high-quality +c-GaN films.
On the applicability ranges of Tc formulas for proximity-coupled thin SN and SS bilayers
Authors: Kubo Takayuki 
Published: January 2025

Abstract
This Brief Note revisits the well-established T

c
formulas for proximity-coupled thin superconductor-normal conductor (SN) and superconductor-superconductor (SS) bilayers. While several formulas exist, their interrelations and ranges of validity are not well documented, which can often lead to misapplication and potential misinterpretation of experimental data. To address this issue, the note clarifies these relationships and applicability ranges, offering guidance for their proper use in experimental and applied settings. McMillan's formula is recommended for SN bilayers due to its broad applicability, with its SS counterpart providing similar reliability.

Mini Review: The Strategic Approach of Saponin to Reducing Methane Emissions
Authors: Sami Mshary Ghasaq , Castillo Cristina , Hernandez Joaquin , Muiño Rodrigo 
Published: January 2025

Ruminant production is facing a critical period within global agriculture due to unique digestive systems allowing them to utilize low-quality fibre-rich feed, producing the potent greenhouse gas methane (CH4) as a by-product. Methane is eliminated from the atmosphere by eructation. Saponins are secondary metabolites in plant seeds, leaves, bark, and roots. Some saponins were found from legumes and microbial populations, including Quillaja saponaria, Yucca schidigera, Camellia sinensis and Samanea saman. Saponin consists of a lipophilic triterpene or steroid aglycone attached to one or more hydrophilic sugar moieties. Their structural variety has appeared in their chemical and biological properties. Numerous pharmacological aspects of saponin include antifungal, antiprotozoal, anti-microbial, and anti-methanogen effects. More factors are related to the rumen microbe’s power to mitigate the antiprotozoal activity of saponins, such as breeds of animals and the environment. Tannin and saponin having plant species, such as alfalfa are widely utilized because of their beneficial matter and clearly can decrease methane production. The membrane-disrupting action of saponins illustrates their harmful influence on protozoa and the formation of complexes with sterols found in the protozoal cell wall, thereby causing cell lysis. This review aims to understand saponin structural features and focus on the prospect of being a useful resource for researchers in using saponin extract as a bioactive compound in ruminant diets to mitigate greenhouse gas emissions
Glycogen Storage Disease Type Ia: A Retrospective Claims Analysis of Complications, Resource Utilization, and Cost of Care
Authors: Kruger Eliza , Nedzesky Justin , Thomas Nina , Dunn Jeffrey D. , Grimm Andrew A. 
Published: January 2025

Background: Glycogen storage disease type Ia (GSDIa) is a rare inherited disorder resulting in potentially life-threatening hypoglycemia, metabolic abnormalities, and complications often requiring hospitalization. Objective: This retrospective database analysis assessed the complications, resource utilization, and costs in a large cohort of patients with GSDIa. Methods: We conducted a retrospective cohort study of GSDIa patients and matched non-GSDIa comparators utilizing the PharMetrics® Plus database. International Classification of Diseases, Tenth Revision (ICD-10) diagnosis codes in any billing position for inpatient and outpatient claims (January 2016–February 2020) were identified for complications related to GSDIa. Healthcare use and costs were assessed by setting of care (inpatient, outpatient, physician office, emergency department, and pharmacy). Results: Overall, 557 patients with GSDIa and 5570 matched comparators (male, 63%; adults, 67%) were identified. The most frequent complications in patients with GSDIa vs comparators included anemia due to enzyme disorders (odds ratio, 4.0 × 103; 95% confidence interval, 555.9–2.8 × 104), hepatocellular adenoma (305.9; 41.6–2.2 × 104), liver transplantation (164.6; 21.8-1.2 × 103), and gastrostomy (152.2; 61.1-379.2), as well as acidosis (45.5; 29.4-70.3), hepatomegaly (43.6; 29.1-65.3), hyperuricemia (23.6; 11.9-46.9), and hypoglycemia (20.2; 14.3-28.7). Chronic complications (eg, gout, osteoarthritis, chronic kidney disease, and neoplasms) were more common in adults with GSDIa, whereas acute complications (eg, poor growth, gastrostomy, seizure, and hypoglycemia) were more common in children with GSDIa. Patients with GSDIa more often required hospitalization (0.53 vs 0.06 hospitalizations per patient per year) vs comparators, including 2 or more hospitalizations (26.6% vs 2.3%), longer length of stay (3.1 vs 0.4 days), and more annual visits in all care settings, including 4.3 times more visits in the emergency department. Mean annual total healthcare costs were higher for GSDIa patients vs comparators ($33 910 vs $4410). Discussion: In this large, retrospective database analysis, complications observed among patients with GSDIa were consistent with prior reports and demonstrate the chronic and progressive nature of the disease. Resource utilization was substantial in GSDIa patients, and mean annual total healthcare costs were almost 8 times higher than those of comparators. Conclusions: GSDIa is associated with numerous potentially serious and sometimes fatal complications, extensive resource utilization, and high management costs.

A Mordida Aberta Anterior (MAA) é uma das más oclusões de maior comprometimento estético e funcional, ela se trata de uma deficiência no contato vertical entre os dentes antagonistas, ou ainda, como a presença de uma dimensão vertical negativa entre as bordas incisais dos dentes anteriores superiores e inferiores.Foi realizado uma revisão de literatura, na qual foram selecionados estudos que eram pertinentes com o título proposto “tratamento de mordida aberta anterior em crianças de 4 a 6 anos”. A pesquisa foi feita utilizando descritores “Má Oclusão”; “Mordida aberta”, “Odontopediatria” em português e em inglês: “Open bite”, “Malocclusion” e “Pediatric dentistry”, nas plataformas de bases de dados online: PUBMED (National Library of Medicine National Institutes of Health dos EUA), SCIELO (Scientific Electronic Library Online) e BVS (Biblioteca Nacional em Saúde) com trabalhos indexados no período de 2019 a 2024. Foi observado que o tratamento da mordida aberta anterior em crianças de 4 a 6 anos apresenta melhores resultados quando realizado precocemente, combinando terapias interceptivas e comportamentais. A abordagem interdisciplinar é essencial para promover o correto desenvolvimento da oclusão e prevenir complicações futuras.
A Report from Madrid (Spain) on the Total Solar Eclipse of 1842 July 8
Authors: Vaquero José M. 
Published: January 2025

Abstract
The total solar eclipse of 1842 July 8, observed from Madrid, was documented by Gerónimo del Campo, interim director of the Madrid Observatory. Published in the “Gaceta de Madrid,” the report describes a luminous corona aligned with the Sun’s center, appearing at totality and disappearing seconds later. The corona displayed pinkish tones, iridescence, and divergent rays. Additional phenomena included a bluish-livid sky, visible stars (Capella and Aldebaran), and Baily’s beads, all observed through tinted glasses.
Resolved Convection in Hydrogen-rich Atmospheres
Authors: Seeley Jacob T. , Wordsworth Robin D. 
Published: January 2025

Abstract
In hydrogen-rich atmospheres with low mean molecular weight (MMW), an air parcel containing a higher-molecular-weight condensible can be negatively buoyant even if its temperature is higher than the surrounding environment. This should fundamentally alter the dynamics of moist convection, but the low-MMW regime has previously been explored primarily via 1D theories that cannot capture the complexity of moist turbulence. Here, we use a 3D cloud-resolving model to simulate moist convection in atmospheres with a wide range of background MMWs and confirm that a humidity threshold for buoyancy reversal first derived by T. Guillot coincides with an abrupt change in tropospheric structure. Crossing the “Guillot threshold” in near-surface humidity causes the dry (subcloud) boundary layer to collapse and be replaced by a very cloudy layer with a temperature lapse rate that exceeds the dry adiabatic rate. Simulations with reduced surface moisture availability in the lower atmosphere feature a deeper dry subcloud layer, which allows the superadiabatic cloud layer to remain aloft. Our simulations support a potentially observable systematic trend toward increased cloudiness for atmospheres with near-surface moisture concentrations above the Guillot threshold. This should apply to H2O and potentially to other condensible species on hotter worlds. We also find evidence for episodic convective activity and associated variability in cloud cover in some of our low-MMW simulations, which should be investigated further with global-scale simulations.
« Pèlerinage aux lieux saints » des animés et « regard touristique » : l’exemple de la série Hyōka et la ville de Takayama
Authors: Sutō Shin.ya 
Published: January 2025

La pratique de fans consistant à visiter des lieux représentés dans des films et séries d’animation est qualifiée de « pèlerinage aux lieux saints » (seichi junrei), un phénomène qui s’est popularisé au Japon à la fin des années 2000. Cet article retrace son histoire, et présente ses spécificités à travers l’exemple de l’animé Hyōka (2012). Celui-ci prend pour cadre Takayama, une ville touristique connue pour ses quartiers historiques, mais en représente plutôt les lieux ordinaires dans lesquels évoluent ses protagonistes lycéens. Ainsi, les « pèlerins » de cet animé, au cours de leur visite, peuvent découvrir le « véritable visage » de cette ville. Cependant, l’article montre que cette « authenticité » se voit elle-même réintégrée dans la perspective de l’exploitation marchande du phénomène.
Films japonais contemporains et représentations d’un pays perdu : des nostalgies à l’œuvre
Authors: Brosseau Sylvie 
Published: January 2025

Dans de nombreux films japonais récents, nous constatons la présence récurrente de lieux dotés d’une forte typicité : maisons « traditionnelles » avec genkan (vestibule), jardin, engawa (galerie vitrée), pièces à tatamis ; sentō (bain public) ; petite gare le long d’une ligne locale parcourant la campagne, etc. Ces espaces donnent lieu à des pratiques collectives maintenant des liens forts avec les saisons, où la convivialité est manifeste : repas, bains, vie de quartier. Alors que ces lieux et pratiques semblent s’éloigner de la vie réelle des habitants du Japon, leurs représentations abondent dans les films. Cet article décrit et analyse les images de ces divers topos sous l’angle de la nostalgie, afin de saisir en quoi cela concerne des questions culturelles dans le Japon contemporain.
Les négociations de la convention franco-ryūkyū : micro-histoire d’une relation diplomatique
Authors: Shimooka Erina 
Published: January 2025

La convention franco-ryūkyū a été conclue le 24 novembre 1855. Elle a été signée après six négociations officielles et deux entrevues non officielles entre le représentant français, Nicolas François Guérin, et des fonctionnaires aux postes fictifs du royaume. Ayant été conclue à la suite de la manifestation militaire, cette convention est considérée comme un traité inégal. Toutefois, le royaume des Ryūkyū avait obtenu une concession sur le contenu de la convention, la « diplomatie de la canonnière » française n’a pas eu beaucoup d’effet. Tout au long des pourparlers, la France et le royaume des Ryūkyū ont tous les deux utilisé leurs stratégies diplomatiques à la fois pour tenter de faire avancer les négociations en leur faveur et pour trouver un compromis.
Crise en Nouvelle-Calédonie : à la recherche d’une méthode pour la « mission de médiation et de travail »
Authors: Meyer Nadège 
Published: January 2025

À l’heure du bilan de l’Accord de Nouméa qui devait permettre l’adoption consensuelle d’un nouveau statut institutionnel pour la Nouvelle-Calédonie, un projet de loi constitutionnelle révisant le corps électoral aux élections provinciales de ce territoire a été l’élément déclencheur d’une quasi-guerre civile. La méthodologie mise en œuvre par le Président de la République a consisté depuis à confier à trois hauts fonctionnaires une « mission de médiation et de travail » afin de parvenir à un accord global permettant de modifier le statut constitutionnel sui generis dont dispose jusqu’à présent la Nouvelle-Calédonie au sein de la République française. En novembre dernier, elle s’est poursuivie par des entretiens politiques lors du passage en Nouvelle-Calédonie, des Présidents du Sénat et de l’Assemblée nationale. La récente nomination de Manuel Valls en qualité de ministre des Outre-mer permettra peut-être de faire évoluer cette méthode pour qu’émerge un accord durable.
Transformations in the governance of French medical laboratories
Authors: Leymarie Antoine 
Published: January 2025

In France, private medical laboratories (PMLs) were at the heart of the fight against the Covid-19 pandemic. Each year biological examinations account for over 70 % of all medical diagnoses. Although the health crisis put the spotlight on this sector, no targeted social science work has been carried out on it. However, since the early 2000s, PMLs have undergone significant changes in terms of concentration, industrialisation and financialisation that has radically changed the landscape of the sector. In the space of two decades, the number of PMLs has fallen from 4000 to around 300 and almost 80% of them are now owned by six financial groups. This article traces the history of this sector, from its “birth” in the 1970s to the present day, and through it, that of a profession: medical biologists. To do so, we mobilize the Régulation theory “sectoral approach” – which focuses on sectoral idiosyncrasies – enriched by the sociology of the professions. In the first section, we analyse the historical dynamics of the “French medical biology model” and its rise during the 1980s. Secondly, we examine the crisis of this model in the early 2000s, further to various reforms and because of the strategies of Private Equity and professional players. In section 3, we put forward an analysis of the new mode of regulation – industrial and financial – as well as the organisational and professional transformations that medical biologists are facing.
