Que peuvent les algorithmes de plongement de mots pour l’analyse sociologique des textes ? Analyser les discours et caractériser les locuteurs des plateformes « Grand Débat National » et « Vrai Débat »
Authors: Suignard Philippe , Escoffier Caroline , Charaudeau Lou , Brugidou Mathieu
Published: January 2025

In this contribution we propose to contribute to the evaluation of algorithms called “ word embedding” to the sociological analysis of texts : on the one hand, by comparing the results of semantic analyses of these algorithms with the now well-known approaches of textual data analysis ; on the other hand, by focusing on what constitutes one of the main obstacles to the sociological analysis of the web : the difficulty to sociologically characterize the authors of statements from the web. To do this, we analyze the statements coming from two platforms of “civic tech” – the governmental platform, the “Grand Débat National”, and its political and algorithmic response proposed by a collective of Yellow Vests, the “Vrai Débat”. A third corpus from the “Entendre la France” platform, with the same design as that of the “Grand Débat National” and documented in terms of socio-political properties, will allow us to characterize the speakers according to their discourse and to try to predict, using machine learning approaches, the “ pseudo properties” assigned to the speakers of the “Grand Débat National”.

Published: January 2025

Light curves serve as a valuable source of information on stellar formation and evolution. With the rapid advancement of machine learning techniques, they can be effectively processed to extract astronomical patterns and information. In this study, we present a comprehensive evaluation of models based on deep learning and large language models (LLMs) for the automatic classification of variable star light curves, using large datasets from the Kepler and K2 missions. Special emphasis is placed on Cepheids, RR Lyrae, and eclipsing binaries, examining the influence of observational cadence and phase distribution on classification precision. Employing automated deep learning optimization, we achieve striking performance using 2 architectures: one that combines one-dimensional convolution (Conv1D) with bidirectional long short-term memory (BiLSTM) and another called the Swin Transformer. These achieved accuracies of 94% and 99%, respectively, with the latter demonstrating a notable 83% accuracy in discerning the elusive type II Cepheids that comprise merely 0.02% of the total dataset. We unveil StarWhisper LightCurve (LC), a series of 3 LLM models based on an LLM, a multimodal large language model (MLLM), and a large audio language model (LALM). Each model is fine-tuned with strategic prompt engineering and customized training methods to explore the emergent abilities of these models for astronomical data. Remarkably, StarWhisper LC series models exhibit high accuracies of around 90%, considerably reducing the need for explicit feature engineering, thereby paving the way for streamlined parallel data processing and the progression of multifaceted multimodal models in astronomical applications. The study furnishes 2 detailed catalogs illustrating the impacts of phase and sampling intervals on deep learning classification accuracy, showing that a substantial decrease of up to 14% in observation duration and 21% in sampling points can be realized without compromising accuracy by more than 10%.
A Systematic Study on Digital Light Processing 3D Printing of 0-3 Ceramic Composites for Piezoelectric Metastructures

Published: January 2025

Digital light processing (DLP) is a high-speed, high-precision 3-dimensional (3D) printing technique gaining traction in the fabrication of ceramic composites. However, when printing 0-3 composites containing lead zirconate titanate (PZT) particles, a widely used piezoelectric ceramic, severe density and refractive index mismatches between the 2 phases pose challenges for ink synthesis and the printing process. Here, we systematically and quantitatively optimized DLP printing of PZT composites, streamlining process development and providing a solid theoretical and experimental foundation for broader applications of DLP technology. PZT particles were pretreated with air plasma to improve slurry uniformity and enhance stress transfer at the composite interface, leading to improved chemical modification, mechanical strength, and piezoelectric properties. We investigated the effects of key process parameters on printability and accuracy by analyzing the curing behavior of PZT–polymer composites. A quantitative model of the DLP curing process was introduced. Unlike stereolithography (SLA), DLP curing depth was found to depend on energy dose and light intensity, with higher intensities proving more favorable for printing 0-3 PZT composites. From depth/width–energy curves, optimal process parameters were determined. We designed and fabricated a soft piezoelectric metamaterial-based touch sensor using these parameters, achieving a customized output profile. This work offers critical insights into optimizing DLP for functional materials and expands the potential of 3D-printed piezoelectric composites.

Reflexive and Metacognitive Determinants of Professional Activity of IT Specialists
Authors: Karpov Alexander A. , Prisyazhnyuk Sergey O. , Sharshakova Anastasiya S.
Published: January 2025

The article presents the results of a study of reflexive and metacognitive regulation of professional activity of IT specialists: analysts and programmers. It is shown that these types of information activities have a structural rather than analytical determination in relation to the main reflexive and metacognitive parameters. Patterns have been established according to which the structural organization of the main reflexive and metacognitive determinants differs both relative to the indices of the structural organization and in comparison with each other according to the criterion of homogeneity-heterogeneity, revealing qualitative differences among themselves due to the peculiarities of professional activity of each of the groups. They are differentiated according to professional affiliation and gender criterion. The ideas about the specifics of the relationship between antireflexion and other reflexive and metacognitive characteristics, mainly reflection, are formulated. It is negative with an equally high level of severity of each of them, which indicates the “suppression” of a high measure of development of one parameter by an equally high level of severity of the second, which does not reduce the overall potential of the structure, but on the contrary, strengthens it. Thus, a new type of connection in the structure is explicated – “inhibitory”, which reflects not synergistic effects, but also non-compensatory tendencies. The obtained results are based on the characteristics of a new subject-information class of activity.

Authors: Tikhomirova Elena V. , Krylova Natalia G. , Umanskaya Irina A. , Golubev Valery V. , Krylova Anastasiya A.
Published: January 2025

The article discusses issues of understanding the phenomenon of bullying in the teaching community. The specificity of the semantic content of the phenomenon of “bullying” is revealed among teachers with different professional experience and with varying degrees of professional burnout. It is concluded that in the semantic space of teachers with different professional experience, the concept of “bullying” has both stereotypical and specific features associated with the experience of resolving such situations, the degree of understanding of the sociocultural context due to age. The semantics of the concept of “bullying” among experienced teachers is more complete. For teachers with a low level of professional burnout, the perception of bullying is not associated exclusively with the children's community, and is not associated with a high degree of novelty of the phenomenon.

Published: January 2025

The article considers textural and structural features of hematite-carbonate rocks associated with carbonate-sulfde clastic ores of the Yubileynoe massive sulfde deposit, South Urals. Some hematite-carbonate rocks exhibit signatures of the replacement of sulfde clasts and hyaloclasts by hematite-carbonate material, classifed as carbonate analogs of gossanites. The hematite-carbonate aggregates after sulfde clasts are characterized by inherited reniform-colloform, radial and crystalline-granular structures, as well as the inclusions of relict sulfdes and tellurides. The hematite-carbonate aggregates after sulfde clasts contain the elevated concentrations of chalcophile (Cu, Zn, Pb, As, Sb, Bi, Te) and lithophile (Ti, Zr, V, W) trace elements. The hematite-carbonate clasts after hyaloclasts contain aggregates with globular structure and syneresis cracks and contain relics of chlorite. The matrix of hematite-carbonate rocks consists of calcite with inclusions and aggregates of dolomite, chlorite, quartz and apatite. Late sulfde mineralization (pyrite metacrystals, aggregates and veins of chalcopyrite and sphalerite) is characteristic of both hematite-carbonate rocks after sulfde clasts and hyaloclasts.
Enrichment of massive sulfdes from the Semenov hydrothermal cluster (Mid-Atlantic ridge) in barite: a result of E-MORB involvement and magmatic contribution
Authors: Melekestseva I.Yu. , Tret’yakov G.A. , Beltenev V.E.
Published: January 2025

The paper reviews and compares the barite fndings in hydrothermal felds of the mid-oceanic ridges. The genetic signifcance of barite is considered for the Semenov hydrothermal sulfde cluster associated with an oceanic core complex (OCC) at 13°30? N of the Mid-Atlantic Ridge. Massive sulfdes of the Semenov-1, -3, and -4 felds are enriched in barite (up to 20 vol. %) and therefore Ba (up to 4.12 wt. %). The presence of a signifcant amount of barite and a high Ba content of massive sulfdes of the OCC-related felds link their formation with E-MORBs. Magmartic contribution for the formation of massive sulfdes from some Semenov felds is supported by negative values of S isotopic composition of sulfdes associated with barite, the presence of magmatic gases (CO2 and SO2) in Raman spectra of fuid inclusions in barite and the results of physicochemical modeling, which indicate the formation of barite-sulfde assemblage upon the interaction of E-MORBs, seawater, and magmatic gas. The results of modeling of the system with felsic rocks show that oceanic plagiogranites from OCC structure could be an additional supplier of Ba.

Published: January 2025

Horizons enriched in phosphorus are identifed in ooidal ironstones underlying the oxide-carbonate manganese ores of the Marsyaty deposit (Northern Urals). The maximum P2O5 content reaches 6.37 wt. % in a quartz sandstone interbed with ooids consisting of Fe3+ oxyhydroxides and is associated with authigenic fuorapatite. In iron oxyhydroxide ooidal ores, phosphorus is present mainly as apatite, which forms massive and radial zones in both the ooids and the matrix. In siderite ooidal ores, the phosphate minerals include apatite and hydrous Al and Ca silicate-phosphates, possibly a mineral of the crandallite-goyazite series and perhamite. They occur as radial aggregates emphasizing the zonation of carbonate ooids and common in the matrix. Phosphorus is also part of an authigenic rhabdophane-like mineral flling the radial and concentric cracks in iron oxyhydroxide ooids. Some phosphorus is associated with detrital monazite and apatite. Phosphorus for the formation of phosphates was most likely sourced from organic relics, whereas seawater and minerals unstable under sedimentation and diagenesis conditions were the source of cations. The formation of crystalline phosphates is associated with diagenetic processes, during which the organic relics were fermented and replaced by mineral phases, while the minerals metastable in shallow marine basin were decomposed with desorption of elements captured by Fe3+oxyhydroxides from seawater.

TOTAL EXPOSURES TO СURRENCY RISKS OF UKRAINIAN PUBLIC AGRICULTURAL COMPANIES
Authors: YATSENKO Valeria
Published: January 2025

Introduction. The unpredictable volatility of foreign exchange rates is essential to economic agents' financial and economic performance, leading to currency risks. The most popular method of assessing currency risks is the application of asset pricing models, which define currency risk as the sensitivity (elasticity) of the market value of companies or their stock share returns to fluctuations in foreign exchange rates. This is called the total exposure of currency risks and is reflected by the corresponding coefficient of single-factor regression.

The purpose of the article is to investigate and assess the currency risks of Ukrainian agro-industrial companies based on the use of the conventional capital asset pricing model (CAPM) to fluctuations in the hryvnia to US dollar exchange rate and the trade-weighted index, and also, taking into account the peculiarities of the Ukrainian economy and its confident European integration movement, to identify the sensitivity of stock returns to the volatility of the hryvnia to the euro exchange rate.

Results. Considering the characteristics of the Ukrainian economy and its confident Eurointegration movement, besides the US dollar exchange rate, we study the sensitivity of stock returns to the volatility of the euro and the trade-weighted hryvnia index. The empirical base is data from 11 publicly traded agricultural companies listed on the Warsaw, London and Paris stock exchanges. We have found that most Ukrainian companies demonstrate a positive sensitivity to the decline in the hryvnia's value (growth of its exchange rate), confirmed by significant coefficients. It correlates with theoretical assumptions about improving export-oriented companies' competitiveness in the context of a national currency's devaluation. The exposure of the trade-weighted hryvnia index appeared slightly higher compared to the exposure to the US dollar, while the sensitivity to the euro, on the contrary, is noticeably lower. It creates the possibility for diversification of companies' risks.

Conclusions. Contrary to the majority of previous works of foreign scientists, this study does not reveal an anomaly of currency risk exposure – Ukrainian agricultural companies demonstrate statistically and economically significant sensitivity to exchange rate fluctuations. One can explain it by the sample and the highly open economy in general. The results identify the possibility for Ukrainian companies to obtain positive effects from hryvnia devaluation if effective management decisions are made.

A wafer-bonded vertical-cavity surface-emitting laser (VCSEL) was demonstrated by surface-activated bonding (SAB) of a GaAs-based distributed Bragg reflector (DBR) on a Ge substrate. Current injection lasing was achieved at the 1380 nm band under continuous-wave operation with AlGaInAs-based multi-quantum wells and a buried tunnel junction for current and optical confinement. The thermal conductivity of the VCSELs bonded by SAB was superior to that of InP VCSELs owing to high heat dissipation of GaAs DBR. This bonding method is suitable for short-wavelength infrared VCSELs and various other applications, including sensing, data communication, and silicon photonics.

Quality of care for migrant populations with type 2 diabetes mellitus: a retrospective analysis of the AMD Annals
Authors: Occhipinti, M.
Published: January 2025

La presenza di disparità nei pazienti affetti da diabete mellito di tipo 2 (T2D) in base alle regioni geografiche è stata ampiamente ipotizzata; tuttavia, ad oggi, informazioni complete circa la qualità di cura delle popolazioni migranti con diabete sono ancora mancanti. A questo scopo abbiamo analizzati gli indicatori dei dati degli annali AMD 2022, per valutare eventuali disparità di esito o di qualità di cura nei pazienti stranieri rispetto ai pazienti europei. Fra tutti i pazienti con diabete mellito tipo 2 attivi, sono stati selezionati quelli in cui era presente in cartella l’informazione riguardo il paese di origine. È stata utilizzata la classificazione ISTAT per la definizione dell’area geografica di origine e sono stati valutati per singolo paese di provenienza i principali indicatori di processo, di esito intermedio, finale e score Q. Le informazioni sul Paese di origine erano disponibili per 179.536 pazienti con T2D. Di questi il 19.3% presentava una provenienza straniera e i principali paesi di origine  per numerosità del campione sono risultati il Nord Africa, Centro-Est Europa, Centro e Sud Asia e Centro- Sud America. I pazienti stranieri sono più giovani con un delta di oltre 20 anni se paragonati ad esempio al Asia centro-meridionale e con conseguente più breve durata di malattia. La valutazione degli indicatori di processo mostra buona aderenza alle indicazioni diabetologiche con minor attenzione al dosaggio della microalbuminuria e allo screening della retinopatia. Complessivamente gli indicatori di intensità/appropriatezza sono risultati più bassi nelle popolazioni provenienti dal Nord ed Ovest Africano e dal Centro e Sud Asia. L’utilizzo di terapie innovative è stato invece paragonabile a quanto accade nella popolazione europea. Lo Score Q medio più basso è risultato nei pazienti dell’Africa occidentale (26,4 ±9,1 vs 29,1±8,0) e la percentuale di pazienti con più basso score Q>25 è stata ritrovata nei pazienti provenienti dall’Asia centrale e meridionale (51,6%) e dell’Africa occidentale (50,1%), ma anche dall’Est Europa (53,1%), con quasi 10 punti percentuali in meno. Complessivamente sono emerse differenze di età, durata di malattia e intensità di trattamento tra i pazienti provenienti da diverse aree geografiche. La tipologia di trattamento offerto mostra un’attenzione ad un utilizzo equo delle terapie farmacologiche ma i risultati, sebbene non così distanti suggeriscono la necessità di interventi terapeutici ancora più mirati a superare le diverse barriere esistenti.

The management of patients with lipid disorders in Italian diabetes centers: results of a national survey
Authors: Da Porto, A.
Published: January 2025

La malattia cardiovascolare (CV) aterosclerotica rappresenta la prima causa di morbilità e mortalità nel mondo occidentale, in particolare per le persone con diabete. Il diabete e l’iperglicemia che lo caratterizza rappresentano infatti essi stessi un potente fattore di rischio CV, pertanto, è indispensabile nelle persone con diabete perseguire contemporaneamentenon solo l’ottimizzazione del controllo glicemico ma anche del colesterolo LDL con l’obbiettivo di abbattere il rischio di sviluppare eventi cardiovascolari maggiori. Nella pratica clinica tuttavia molto spesso i nostri pazienti presentano dei livelli di colesterolemia LDL lontani da quelli che dovrebbero essere gli obbiettivi che le linee-guida raccomandano. Questo fenomeno è in parte dovuto ad un sotto trattamento dei fattori di rischio cardiovascolare da parte dei clinici e in parte attribuibile ad una scarsa aderenza terapeutica dei nostri pazienti. Negli ultimi anni la ricerca scientifica ha messo a disposizione di medici e pazienti nuove molecole molto efficaci nel ridurre la colesterolemia LDL e potenzialmente capaci di favorire l’aderenza terapeutica dei pazienti in virtù della facilità di utilizzo, degli scarsi effetti collaterali e della possibilità di essere assunti dal paziente mensilmente o addirittura semestralmente a vantaggio della aderenza alla terapia. Ad oggi tuttavia non tutti i diabetologi italiani sono messi nelle condizioni di utilizzare al meglio questa nuova arma a disposizione per la cura dei propri pazienti, sia per problematiche di origine burocratica che di tipo organizzativo. Scopo di questa survey è quindi quella di valutare tra un gruppo rappresentativo di diabetologi italiani quale sia lo stato dell’arte nella gestione della dislipidemia nelle varie realtà dove essi operano.

Die Störung der neuromuskulären Übertragung an der motorischen Endplatte, erfordert bei Patienten mit Myasthenia gravis (MG) den reduzierten Einsatz von Muskelrelaxantien. Cisatracurium kann bei Patienten mit MG, auf Grund seiner speziellen Pharmakokinetik (Hofmann-Elimination), besser kontrollierbare Narkosebedingungen herbeiführen
Neue Medizintechnik in der Luftrettung.

Published: January 2025

Die Zunahme der Rettungseinsätze mit der Verlegung von intensivpflichtigen Patienten gewinnt im Aufgabenspektrum der Luftrettung zunehmend an Bedeutung. Dabei kommt es nicht mehr in erster Linie auf einen schnellen und schonenden Transport an, sondern auch auf den Beginn, die Weiterführung und Änderung intensivmedizinischer Behandlungsstrategien. In Folge dessen ändern sich kurzfristig die medizintechnischen Kenntnisse des fliegenden Personals. Innovative Behandlungsmethoden wie die Intraaortale Ballonpulsation bei Patienten nach Myokardinfarkt und Low Cardiac Output Syndrom (LCOS), neue Beatmungsgeräte und spezielle Beatmungsstrategien in der Therapie des ARDS, die extrakorporale Membranoxygenierung und Bed Side Analysen verlangen Kenntnis und Ausbildung in der angewendeten Medizintechnik. Diese werden durch die Betreiberverordnung (MPBetreibV) §2 Abs.2§5 Abs.2, §2abs.1ff; §9Abs.1; §13 Satz1,3 und 4, das Medizinproduktegesetz (MPG) und durch das 1. Änderungsgesetz zum MPG, MedGV §6Abs.3; §10 Abs. 1; §6 Abs.4; §14 Abs.1 gesetzlich festgeschrieben. Um so fahrlässiger ist die Tatsache einzuschätzen, dass innerhalb der Nutzung medizintechnischer Geräte 64 % Bedienungsfehler, 18% Instandhaltungsfehler, 11% Konstruktions-, Fertigungs- bzw. Materialfehler und nur 8% Gerätefehler zu verzeichnen sind.
Simulation in Medicine
Authors: Schedler Olaf
Published: January 2025

The simulation medicine is mainly concerned with the factor of "Human Factors". This term, the so-called "human factor" it is considered as a collective term for all mental, cognitive and soziÂ¬alen factors in socio-technical, and human-machine systems. Investigations also revealed that deaths were due to "preventable error" in more than 80%. Root cause analysis in anesthesia showed that up to 70% of incidents are theoretically preventable. The literature fluctuates in various fields between 70 to 85% "preventable error". This is an impressive numbers with a clear need for action.
Remifentanil zur postoperativen Analgesie bei Patienten mit Myasthenia gravis nach videoassistierter thorakoskopischer Thymektomie.
Authors: Schedler Olaf , Grebe Dirk , Werner Joerg
Published: January 2025

Die postoperative Schmerztherapie bei Patienten mit Myasthenia gravis gestaltet sich auf Grund verschiedener Arzneimittelinteraktionen schwierig. Bolusopioidapplikationen können den Muskeltonus unterschiedlich stark beeinflussen. Periphere Anlagetika können durch Interaktion die neuromuskuläre Transmission verändern. Die Regionalanästhesie (PDA) steht bei thorakoskopischen Operationen in einer ungünstigen Risiko-Nutzen Relation. Opioide mit einer gut steuerbaren Pharmakokinetik können daher zur Schmerztherapie bei Patienten mit Myasthenia gravis von Vorteil sein.

Published: January 2025

Im Jahr 2019 wurden von der ZNA insgesamt 10.642 Behandlungen mit nachfolgender stationärer Weiterbehandlung aufgenommen. 1.430 Patienten (14%) wurden auf der ITS weiterverhandelt. Von den 1.430 ITS-Behandlungen entstanden bei 600 Patientenbehandlungen (41%) statistisch dokumentierte Wartezeiten auf ein ITS-Bett. Bei einer ITS-Aufnahme entstehen grundsätzlich Übernahmewartezeiten. Diese werden jedoch nur dann statistisch erfasst, wenn sie im PTS als wartend auf ein Stationsbett gekennzeichnet wurden. Der Mittelwert aller Bettenwartezeiten beträgt 78±66 Minuten.

Published: January 2025

Um eine erfolgreiche Kompression des Thorax und der Thoraxwand nach geltenden Leitlinien in der Kompressionsfrequenz und Kompressionstiefe zu realisieren, werden automatische Thoraxkompressionsgeräte eingesetzt. Die automatischen mechanischen Thoraxkompressionen (ACD-CPR) mittels medizintechnischer Geräte (corpuls-cpr®) unterliegen bioelastischen Widerständen des Thorax und der Thoraxwand. Der Einfluss der Gravitation wurde für eine ACD-CPR bisher nicht untersucht. Die in der Luftrettung eingesetzten medizintechnischen Geräte zur mechanischen Thoraxkompression unterliegen in den verschiedenen Flugphasen unterschiedlichen Gravitationskräften. Die angestrebte Analyse der CPR Behandlung in der Luftfahrt soll die Kompressionsfrequenz und –tiefe sowie die aufgebrachte Kompressionskraft im Zusammenhang der Gravitationskräfte in der Hyper- und der Mikrogravidität während des 186. Parabelfluges der A310 Air Zero G ermittelten. Ziel der Untersuchung war es, während des Parabelfluges die Effektivität der ACD-CPR zu bestimmen. Gegenüber den Standardmessungen am Boden (smean=5,00±0,01cm/ fmean=100±0,01/min) änderten sich während des Parabelfluges die Kompressionsparameter in der Horizontalflugphase (smean=4,85±0,07cm/ fmean=99,59±1,10/min), in der Hypergraviditätsflugphase (smean=4,84±0,06cm/ fmean=99,11±1,51/min) sowie der Mikrograviditätsflugphase (smean=4,83±0,08cm/ fmean=100±0,00/min) nicht signifikant an dem verwendeten ALS Trainings-Simulationsmodel (QCPR Resusci Anne Laerdal Medical Ltd, Orpington, UK) und der ACD-CPR von corpuls-cpr®. Die Kompressionskraft des corpuls-cpr® lag bei den Standardbodenmessungen bei 571,0±10,5 Newton (N). Während des Parabelfluges veränderte sich die Kompressionskraft auf 574,7±9,60 N im Horizontalflug und auf 570,2±10,78 N in der Hypergravitationsflugphase, um sich in der Flugphase der Mikrogravidität auf 577,5±8,37 N nicht signifikant zu ändern. Einen Einfluss der Gravitationen konnten wir für die Effektivität der automatischen mechanischen Thoraxkompressionen während eines Parabellfluges nicht feststellen.
