AbstractP‐type Sb2Te3 has been recognized as a potential thermoelectric material for applications in low‐medium temperature ranges. However, its inherent high carrier concentration and lattice thermal conductivity led to a relatively low ZT value, particularly around room temperature. This study addresses these limitations by leveraging high‐energy ball milling and rapid hot‐pressing techniques to substantially enhance the Seebeck coefficient and power factor of Sb2Te3, yielding a remarkable ZT value of 0.55 at 323 K due to the donor‐like effect. Furthermore, the incorporation of Nb─Ag co‐doping increases hole concentration, effectively suppressing intrinsic excitations ≈548 K while maintaining the favorable power factor. Simultaneously, the lattice thermal conductivity can be significantly reduced upon doping. As a result, the ZT values of Sb2Te3‐based materials attain an impressive range of 0.5–0.6 at 323 K, representing an almost 100% improvement compared to previous research endeavors. Finally, the ZT value of Sb1.97Nb0.03Ag0.005Te3 escalates to 0.92 at 548 K with a record average ZT value (ZTavg) of 0.75 within the temperature range of 323–573 K. These achievements hold promising implications for advancing the viability of V–VI commercialized materials for low‐medium temperature application.

AbstractThe ternary strategy is one of the effective methods to regulate the morphology of the active layer in organic solar cells (OSCs). In this work, the ternary OSCs with bulk heterojunction (BHJ) or layer‐by‐layer (LbL) active layers are prepared by using the polymer donor PM6 and the non‐fullerene acceptor L8‐BO as the main system and the fullerene acceptor PC71BM as the third component. The power conversion efficiencies (PCEs) of BHJ OSCs and LbL OSCs are increased from 17.10% to 18.02% and from 17.20% to 18.20% by introducing PC71BM into the binary active layer, respectively. The in situ UV–vis absorption spectra indicate that the molecular aggregation and crystallization process can be prolonged by introducing PC71BM into the PM6:L8‐BO or PM6/L8‐BO active layer. The molecular orientation and molecular crystallinity in the active layer are optimized by introducing the PC71BM into the binary BHJ or LbL active layers, which can be confirmed by the experimental results of grazing incidence wide‐angle X‐ray scattering. This study demonstrates that the third component PC71BM can be used as a morphology regulator to regulate the morphology of BHJ or LbL active layers, thus effectively improving the performance of BHJ and LbL OSCs.

AbstractThe family of metal‐free molecular perovskites, an emerging novel class of eco‐friendly semiconductor, welcomes a new member with a unique 1D hexagonal perovskite structure. Lowering dimensionality at molecular level is a facile strategy for crystal structure conversion, optoelectronic property regulation, and device performance optimization. Herein, the study reports the design, synthesis, packing structure, and photophysical properties of the 1D metal‐free molecular perovskite‐related single crystal, rac‐3APD‐NH4I3(rac‐3APD= racemic‐3‐Aminopiperidinium), that features a quantum wire structure formed by infinite chains of face‐sharing NH4I6 octahedra, enabling strong quantum confinement with strongly self‐trapped excited (STE) states to give efficient warm orange emission with a photoluminescence quantum yield (PLQY) as high as ≈41.6%. The study accordingly unveils its photoexcited carrier dynamics: rac‐3APD‐NH4I3 relaxes to STE state with a short lifetime of 10 ps but decays to ground state by emitting photons with a relatively longer lifetime of 560 ps. Additionally, strong quantum confinement effect is conducive to charge transport along the octahedral channels that enables the co‐planar single‐crystal X‐ray detectors to achieve a sensitivity as high as 1556 µC Gyair−1 cm−2. This work demonstrates the first case of photoluminescence mechanism and photophysical dynamics of 1D metal‐free perovskite‐related semiconductor, as well as the promise for high‐performance X‐ray detector.

AbstractA highly effective high‐performance thin‐layer chromatographic methodology has been developed and validated for the concurrent measurement of teneligliptin hydrobromide hydrate and pioglitazone hydrochloride in tablet offering excellent sensitivity, precision, accuracy, and robustness. The methodology involved using aluminum plates layered with silica gel 60F254 were used, and the solvent system consisted of a mixture of chloroform, methanol, and ammonia (8:1:0.5 v/v/v). The analysis involved scanning of the plate at a wavelength of 229 nm and analyzing the resulting densitograms. The linear correlation was established over a range of concentrations 250–3000 ng/band for teneligliptin hydrobromide hydrate and 187.5–2250 ng/band for pioglitazone hydrochloride. The method displayed detection limits of 21.29 ng/band for teneligliptin hydrobromide hydrate and 25.97 ng/band for pioglitazone hydrochloride. The quantification limits were 64.52 ng/band for teneligliptin hydrobromide hydrate and 78.71 ng/band for pioglitazone hydrochloride. The results of precision parameters showed that the % relative standard deviation of peak area was consistently below 2%, indicating high precision. The accuracy of the method was demonstrated to be between 96% and 103%. Proposed method was found to be superior and capable of overcoming the shortcomings of previously reported methods for the assessment of both the drugs.
Policy Implication and Community Interventions to Reduce EDCs Exposure
Authors: Montano Luigi , Guglielmino Antonino 
Published: November 2023

AbstractEndocrine-disrupting compounds (EDCs) as emerging pollutants and multi-target agents have accumulated in the environment at concentration levels inducing significant effects on planet and obviously on all living species so that public concern about the impact of EDCs is constantly growing.Moreover, there are many contaminants in the environment which have never been examined. Even low-level exposure to these chemicals can have significant effects, and the same dose response can have different effects on individuals. Furthermore, the cumulative effects of these chemicals are yet to be studied, thus the effect on human beings is not fully understood. Anyway the health consequences of these chemicals have been particularly studied on reproductive system. Male reproductive health, especially, has represented ideal target for analysing the effects and mechanisms of damage to health of these chemical compounds. This field of health is, indeed, critical for the future of society, not only for interdisciplinary approach of several specialists and institutions involved but also for the educational mission of new generations especially in the vulnerable adolescent period; a mission, about lifestyle, diet, behaviour, personal and social awareness to reduce the exposure to EDCs and prevent non-communicable diseases (NCDs). In this chapter, we will discuss policy Implication and Community Interventions to reduce EDCs Exposure for minimisation health damages in the frame of more recent knowledge on these contaminants and proposing how hazard-based approach to guide and reach the regulations should be preferred to the risk-based one. This approach is particularly important to safeguard the male and female reproductive system, which is the most exposed one to environmental stress.

Published: November 2023

AbstractOver the last 10 decades, the changes in normal environmental conditions, directly or indirectly connected to the presence of several chemical substances released in various ways and means, for many territories, throughout the planet, have become extremely evident, as well as the relative consequences assessed, which involve numerous international working groups. Starting from territorial pollution and known environmental disasters, the World Health Organization, Food and Drug Administration, European Food Safety Authority, European Commission, other international regulatory agencies, scientific societies, and research groups had proposed, through milestone epochs, the methods of study and monitoring of environmentally harmful molecules capable of interfering with the endocrine system, in wildlife, laboratory animals, and humans. Moreover, attention was focused on endocrine functions related to reproductive health and on mechanisms of interaction, during gestation, between fetus, mother, and placenta, in order to bridge the gap of the lack of knowledge in this global theme.
Differential contracting homotopy in higher-spin theory
Authors: Vasiliev M. A. 
Published: November 2023

Abstract
A new efficient approach to the analysis of nonlinear higher-spin equations, that treats democratically auxiliary spinor variables ZA and integration homotopy parameters in the non-linear vertices of the higher-spin theory, is developed. Being most general, the proposed approach is the same time far simpler than those available so far. In particular, it is free from the necessity to use the Schouten identity. Remarkably, the problem of reconstruction of higher-spin vertices is mapped to certain polyhedra cohomology in terms of homotopy parameters themselves. The new scheme provides a powerful tool for the study of higher-order corrections in higher-spin theory and, in particular, its spin-locality. It is illustrated by the analysis of the lower order vertices, reproducing not only the results obtained previously by the shifted homotopy approach but also projectively-compact vertices with the minimal number of derivatives, that were so far unreachable within that scheme.

Published: November 2023

Abstract
We study the contribution of a heavy right-handed Majorana neutrino to neutrinoless double beta decay (0νββ) via four-fermion effective interactions of Nambu-Jona-Lasinio (NJL) type. In this physical scenario, the sterile neutrino contributes to the nuclear transition through gauge, contact, and mixed interactions. Using the lower limit on the half-life of 0νββ from the KamLAND-Zen experiment, we then constrain the effective right-handed coupling between the sterile neutrino and the W boson: $$ {\mathcal{G}}_R^W $$

. Eventually, we show that the obtained bounds are compatible with those found in the literature, which highlights the complementarity of this type of phenomenological study with high-energy experiments.

Zusammenfassung
Hintergrund
Mundgesundheit ist ein wesentlicher Bestandteil der allgemeinen Gesundheit und des Wohlbefindens. Sie wird von vielen Faktoren beeinflusst. Dazu zählen insbesondere individuelle Aspekte wie Mundgesundheitskompetenz und -verhalten. Ziel der Studie war die Bestimmung des konkreten Zusammenhangs zwischen Mundgesundheitskompetenz und -verhalten mit physischer Mundgesundheit.

Methoden
In dieser bevölkerungsbasierten Querschnittsstudie wurden Daten von insgesamt 5510 Personen, welche von 2016 bis 2018 in die Hamburg City Health Study (HCHS) eingeschlossen wurden, mit einem durchschnittlichen Alter von 62,1 Jahren und einem Frauenanteil von 50,7 % ausgewertet. Die physische Mundgesundheit wurde mit den 14 Items des Physical Oral Health Index (PhOX) erhoben. Zur Bestimmung von Mundgesundheitskompetenz und -verhalten wurde ein neu entwickelter Fragebogen mit 10 Aspekten basierend auf dem Oral Health Literacy Adult Questionnaire und der 5. Deutschen Mundgesundheitsstudie genutzt.

Ergebnisse
Der Summenwert der 10 Fragen in Bezug auf Mundgesundheitskompetenz und -verhalten korrelierte signifikant mit dem PhOX-Summenwert (r = 0,23; p < 0,001). Ein Anstieg von einem Punkt des Gesamtwerts zu Mundgesundheitskompetenz und -verhalten war assoziiert mit einer Erhöhung des PhOX-Summenwerts um durchschnittlich 1,45 Punkte. Dies reduzierte sich nur unwesentlich nach Einbeziehung von potenziellen Confoundern wie Alter und Bildung.

Schlussfolgerung
Höhere Mundgesundheitskompetenz und besseres entsprechendes Verhalten sind assoziiert mit einer besseren Mundgesundheit. Damit bilden Mundgesundheitskompetenz und -verhalten wichtige Zielgrößen in der zahnmedizinischen Ausbildung zur effizienten und nachhaltigen Verbesserung der Mundgesundheit in der Allgemeinbevölkerung.

Published: November 2023

ZusammenfassungHintergrundFunktionalität und Behandlungskapazität von Krankenhäusern sind entscheidende Komponenten, um die stationäre Behandlung von Patienten in Krisen und Katstrophen sicherzustellen. Die SARS-CoV-2(„severe acute respiratory syndrome coronavirus type 2“)-Pandemie und der Krieg in der Ukraine zeigen dies. Ziel der vorliegenden Untersuchung ist die Erhebung der Behandlungskapazitäten der Krankenhäuser der Traumnetzwerke der Deutschen Gesellschaft für Unfallchirurgie (DGU) unter der Annahme des Vorliegens einer Schadenslage mit einer Vielzahl zu versorgender Traumapatienten.Material und MethodeZur Erhebung der aktuellen Behandlungskapazitäten in Abhängigkeit von den Prinzipien und Standards der Versorgung wurden die 622 Krankenhäuser der Traumanetzwerke befragt. Hierzu wurde über die Akademie der Unfallchirurgie (AUC) der DGU und eine elektronische Plattform (SurveyMonkey) ein Fragebogen zur freiwilligen Teilnahme an der Umfrage online gestellt. Die hier dargestellten Daten stellen einen auf die Fragestellung dieser Arbeit fokussierten Auszug der Gesamtdaten dar.ErgebnisseAn der Umfrage beteiligten sich 252 der 622 im Dezember 2022 zertifizierten Kliniken (40 %). 250 Datensätze waren verwertbar. Zu gleichen Teilen nahmen lokale, regionale und überregionale Traumazentren teil. Durch eine auf das Überleben fokussierte chirurgische Versorgung („tactical abbreviated surgical care“, TASC) könnten in Bezug auf die abgefragten Szenarien die Versorgungskapazitäten in den einzelnen Sichtungskategorien gesteigert werden. Deutlich wurde aber auch, dass die Verfügbarkeit fertigkeitskompetenter Teams zur chirurgischen Versorgung von Körperhöhlenverletzungen nach wie vor eine Herausforderung darstellt.SchlussfolgerungDurch die Umfrageergebnisse wird dargestellt, in welchem Umfang aktuell in den Krankenhäusern der DGU-Traumanetzwerke Behandlungskapazitäten für die Versorgung von Verletzten und Verwundeten vorliegen und in welchem Maße diese gesteigert werden können. Hierbei kann ein Massenanfall von Verletzten initial lokal und vorübergehend aufgrund der Dynamik zu einer dekompensierten Krisenversorgung führen. Ziel aller Bemühungen und Vorbereitungen muss es daher sein, die Krankenhäuser dauerhaft zu ertüchtigen, dass dies möglichst zuverlässig vermieden werden kann, und diese Überlegungen in die Krankenhausstrukturreform mit einzubeziehen.
Image-based feature extraction for inline quality assurance and wear classification in high-speed blanking processes

Published: November 2023

AbstractWear is one of the key factors that determine the efficiency of multi-stage processes that include blanking operations. Since wear in these processes not only causes unplanned downtime but also directly affects product quality, inline detection of wear and its effect on product quality is of major importance. However, current quality assurance (QA) methods are limited to manual offline inspection by operators at predefined intervals, so that 100% inspection of the product and description of the state of wear is not found in industrial practice. The aim of this work is therefore to develop an optical system that enables in-line acquisition of product images and the associated control of blanking-specific quality features up to stroke rates of 300 strokes per minute (spm). In order to make the system attractive to small- and medium-sized enterprises (SME), the system is designed to minimize integration and investment costs using commercially available components. By combining the system with a methodology for extracting blanking-specific features, so-called key performance parameters (KPPs), the condition of the blanked surface as a relevant quality parameter is derived directly from the workpiece image. To demonstrate the transferability of the methodology to industrial applications, two use cases are investigated. In the first case, the KPPs are used directly to determine the quality of the blanked workpiece and are compared with reference measurements. Here, the KPPs are quantified with a mean absolute error of 18 μm compared to a ground truth. In the second case, the KPPs are used to build a machine learning (ML) model to estimate the wear of the blanking tool. Here, an accuracy of 92% is achieved in classifying the actual wear state.

AbstractL-Arg is a nonessential amino acid but has many physiological roles. Accordingly, L-Arg has been used in various fields, but there is only limited information available about its safety upon overdose. Generally, the no-observed adverse effect level (NOAEL) is used when setting the upper amount for chemical substances. Recently, systematic reviews have been used to assess the safety as well as the effectiveness and usefulness of them. Therefore, we conducted an assessment of the safety of the oral intake of L-Arg in healthy subjects using gastrointestinal symptoms as an index. We limited the study design to only double-blind randomized controlled trials and searched PubMed, Cochrane Library, EBSCOhost, and Ichushi-Web from inception until May 2021. Assessment of the quality of studies was conducted using the Cochrane Collaboration tool and Jadad score, and the random effects model was used for data analysis. Ultimately, 34 studies were selected for inclusion in this work. The dosage of L-Arg used in the studies ranged from 2000 to 30,000 mg/day (or/one-time dose), and the treatment duration was 1–84 days. The increased risk of gastrointestinal symptoms associated with L-Arg intake from 23 studies (647 participants in total) in which such symptoms were reported was 0.01 (95% confidence interval: – 0.02–0.04), which was not significant difference. NOAEL was estimated as 7531 mg/ one-time dose using a weighted change-point regression model (UMIN000046133).Registration and protocol: Umin.ac.jp as UMIN000046133.
Gradient high-performance thin-layer chromatography for characterizing complex hydrocarbon-containing products

Published: November 2023

AbstractClassic saturates, aromatics, resins, and asphaltenes (SARA) analysis has long enabled the chromatographic separation of complex hydrocarbon-containing products into these four families. This simplification often does not provide sufficient or correct information on the relationship between the composition of the products and the process variables studied. The obtention of profiles by gradient automated multiple development (AMD) is an interesting alternative to obtain extended SARA separations with increasing level of complexity for heavy petroleum products that adequately represent the entirety of the sample. An optimized 20-step gradient based on tetrahydrofuran (THF)‒dichloromethane‒n-heptane over a total migration distance of 83 mm is proposed here to characterize all types of heavy oil products. The combination of ultraviolet (UV)–densitometry (at 201, 228, and 273 nm), fluorescence detection by intensity changes using berberine cation, together with on-plate recording of UV spectra of separated peaks and the comparison with those of standards, allow for a deep characterization of chemical families. In the apolar zone of the chromatogram saturates, naphthenes, naphteno-aromatics, alkyl-aromatics, and aromatics with different degrees of condensation are detected. The use of THF, both in the plate precleaning stage and in the first stages of the gradient, is responsible for the satisfactory resolution of the resins in the polar zone. AMD chromatographic zones can be related to peaks from hydrocarbon groups in classical SARA. The application of this gradient to different types of products allowed for the relation of the profiles of bitumen to their origin, differentiation of the resin part trapped in asphaltenes, control performance of deasphalting in hydrorefining products, and the control of the composition of base oils.

Published: November 2023

Abstract
Objective
To evaluate the reliability and validity of a novel method for remotely measuring trismus.

Materials and methods
We recruited 60 volunteers who took three types of photographs at a fixed restricted jaw position mimicking limited mouth opening, including one selfie and one portrait with or without a reference frame. Additionally, the interincisal distance and the width of the upper central incisors were measured with a ruler, as per common practice. Measurements of trismus were made using image analysis software comparing different types of photos and calibration methods. Intraclass correlation coefficient (ICC) and 95% limits of agreement (LoA) with 95% confidence interval were calculated to evaluate reliability and validity.

Results
The proposed method demonstrated high reliability (ICC 0.998; 95% CI 0.997, 0.999). Calibration of photographs using at least a baseline photograph with an external reference frame yielded unbiased measurements and minimised variability. The use of selfies compared to portrait photos also increased variability.

Conclusion
The measurement of trismus can be performed using images taken remotely by patients using their mobile phone cameras. The proposed method is highly accurate, with best results obtained by using a reference frame for calibration of portrait photographs.

Clinical relevance
We propose an easy, cheap, and accurate method that allows for remote and frequent monitoring of trismus in clinical studies using patients’ mobile phones.
