USP38 regulates inflammatory cardiac remodeling after myocardial infarction
Authors: Gong Yang , Kong Bin , Shuai Wei , Chen Tao , Zhang Jing Jing , Huang He
Published: October 2023

Background: The inflammatory response and subsequent ventricular remodeling are key factors contributing to ventricular arrhythmias (VAs) after myocardial infarction (MI). Ubiquitin-specific protease 38 (USP38) is a member of the USP family, but the impact of USP38 in arrhythmia substrate generation after MI remains unclear. This study aimed to determine the role of USP38 in post-MI VAs and its underlying mechanisms.

Methods and results: Surgical left descending coronary artery ligation was used to construct MI models. Morphological, biochemical, histological, and electrophysiological studies and molecular analyses were performed after MI on days 3 and 28. We found that the USP38 expression was remarkably increased after MI. Cardiac-conditional USP38 knockout (USP38-CKO) reduces the expression of the inflammatory marker CD68 as well as the inflammatory factors TNF-α and IL-1β after MI, thereby alleviating advanced cardiac fibrosis, electrical remodeling, ion channel remodeling, and susceptibility to VAs. In contrast, cardiac-specific USP38 overexpression (USP38-TG) showed a significant opposite effect, exacerbating the early inflammatory response and cardiac remodeling after MI. Mechanistically, USP38 knockout inhibited activation of the TAK1/NF-κB signaling pathway after MI, whereas USP38 overexpression enhanced activation of the TAK1/NF-κB signaling pathway after MI.

Conclusions: Our study confirms that USP38-CKO attenuates the inflammatory response, improves ventricular remodeling after myocardial infarction, and reduces susceptibility to malignant VA by inhibiting the activation of the TAK1/NF-κB pathway, with USP38-TG playing an opposing role. These results suggest that USP38 may be an important target for the treatment of cardiac remodeling and arrhythmias after MI.
Customer Archetypes in Hearing Health Care
Authors: Singh Jasleen , Dhar Sumitrajit
Published: October 2023

Purpose:

The purpose of this study is to determine if there are unique customer archetypes that can describe the motivations behind consumer buying choice (in person or online) for hearing aids in hearing health care.

Method:

A consumer survey was developed from themes that arose during 11 semistructured interviews with adults who had no previous hearing aid experience. Using Qualtrics research panels, a 28-item questionnaire was distributed online to U.S. residents above the age of 50 years with no previous hearing aid experience. A quota of 1,000 completed responses was set, with a maximum of 70% of respondents identifying as White. Completed surveys were obtained from 1,377 individuals. Three hundred forty responses were excluded due to ineligibility and/or poor response quality.

Results:

Two unique customer archetypes were developed using five factors identified in the data set: Physician Trust, Sociability, Comfort Buying Online, Verify Sources, and Reliance on Others. Eighty-four percent of respondents chose an in-person pathway for hearing health care. There was no association between customer archetype and pathway selection choice.

Conclusions:

The two archetypes reflect those with greater comfort with consuming health care online and in person, respectively. However, both archetypes are likely to use in-person models of hearing health care at the present time.

The Competition Between Processing and Discourse-Pragmatic Factors in Children's and Adults' Production of Adverbial
When
-Clauses
Authors: Zhang Shijie , Junge Bianca , Lieven Elena , Brandt Silke , Theakston Anna
Published: October 2023

Purpose:

This is the first study to investigate the combined effects of processing-based factors (i.e., clause length and clause order) and discourse-pragmatic factors (i.e., information structure) on children's and adults' production of adverbial
when
-clauses.

Method:

In a sentence repetition task, 16 three-year-old and 16 five-year-old children as well as 17 adults listened to and watched an animated story and then were asked to repeat what they had just heard and seen. Each story contained an adverbial
when
-clause and its main clause. The sentences were manipulated for their clause order, information structure, and clause length.

Results:

Adults tended to change main–
when
clause orders to
when
–main in their repetitions, and they showed a strong preference for the given–new order of information. In contrast, 3-year-olds tended to change
when
–main clause orders to main–
when
, and they showed a preference for the new–given order of information. In addition, 3-year-olds tended to produce short–long clause orders irrespective of what they had heard, whereas adults produced both short–long and long–short orders in line with the input. In general, 5-year-olds were more adultlike in their production compared to 3-year-olds.

Conclusions:

Young children were strongly affected by processing-based factors in their production of complex sentences. They tended to order main and
when
-clauses in a way that requires less planning and processing load. However, they have not yet attained an adultlike sensitivity to discourse-pragmatic factors.

Authors: Perry Jamie L. , Lee Myoung Keun , Tahmasebifard Neda , Gilbert Imani R. , Snodgrass Taylor D. , Shaffer John R. , Schleif Eshan Pua , Weinberg Seth M.
Published: October 2023

Objective:

Understanding the normal anatomy of velopharyngeal (VP) mechanism and the emergence of sexual dimorphism provides valuable insights into differences of VP anatomy among males and females. The purpose of this study is to examine sex differences in VP anatomy in a large data set of 3,248 9- and 10-year-old children.

Method:

Static three-dimensional magnetic resonance imaging was used to compare five VP characteristics including velar length, velar thickness, effective velar length, levator veli palatini muscle length, and pharyngeal depth between age-matched males (
n
= 1,670) and females (
n
= 1,578). Additionally, these dimensions were used to determine the VP ratio and effective VP ratio.

Results:

Males showed significantly larger dimensions for all VP distances and significantly lower ratios of velar length and effective velar length to pharyngeal depth (
p
< .05). The magnitude of these effect sizes was small to medium, with Cohen's
d
values ranging from 0.12 to 0.63. Additionally, the VP ratio and effective VP ratio are lower among males compared to females (
p
< .05).

Conclusions:

Results suggest the presence of sexual dimorphism in the VP mechanism among 9- and 10-year-old children. These findings emphasize the necessity of using different normative data for males and females when making comparisons to patients with cleft palate.
Is Research on Augmentative and Alternative Communication Intervention With Children With Autism Spectrum Disorder Reflected in the Clinical Practice of Speech-Language Pathologists?
Authors: Wendelken Meghan E. , Williams Diane L.
Published: October 2023

Purpose:

Individuals with autism spectrum disorder (ASD) who have little to no functional speech require augmentative and alternative communication (AAC). Research on AAC intervention with individuals with ASD consistently indicates that teaching requesting skills has been the primary focus, with limited guidance on teaching social communication skills, despite the critical impact of these skills on language development. Furthermore, receptive language is typically not considered when measuring responsiveness to intervention. Thus, it is unclear how individuals with severely affected receptive language respond to current intervention techniques and whether these techniques support generalization of skills. The purpose of this qualitative study was to determine if clinical practice follows the patterns observed in the research literature and to learn more about how intervention techniques are impacting individuals in this population.

Method:

Thirteen practicing speech-language pathologists (SLPs) were interviewed to describe AAC intervention with this population. An interpretive phenomenological approach was used to analyze qualitative data and identify unique themes.

Results:

Seven primary themes emerged related to intervention targets, requesting, social communication, motivation, receptive language, perceived efficacy and challenges, and communication partners. Subthemes for each primary theme are described.

Conclusions:

Clinical practice resembles the research literature, as SLPs emphasize requesting and report the use of evidence-based strategies. However, SLPs reported a lack of guidance for teaching social communication, limited generalization of skills, and lack of AAC uptake by communication partners. Finally, SLPs may not consider individual receptive language abilities when making clinical decisions related to AAC. This article indicates a robust need to identify more effective AAC intervention methods that promote social communication, meet the needs of children with severely affected receptive language, and include families to improve outcomes.
Constraining the formation history of the HAT-P-11 system using atmospheric abundances
Authors: Chatziastros Lena , Bitsch Bertram , Schneider Aaron David
Published: October 2023

The chemical fingerprint of a planet can reveal information about its formation history regarding when and where the planet formed. In particular, the water content of a planet can help to constrain its formation pathway: If the planet formed in the outer regions of the disk and migrated inward, it would be water-rich due to the accretion of water-ice-rich solids. Conversely, formation in the inner disk region, where water-ice is not available, would result in a smaller atmospheric water content due to the limited accretion of water vapor. However, this process becomes complex with the presence of gap-opening giant planets. A gas giant exerts a pressure bump exterior to its orbit, preventing further influx of pebbles into the inner system, resulting in a water-poor environment and eventually leading to water-poor inner planets. These different formation scenarios can help to constrain the formation of the HAT-P-11 system, which contains an inner sub-Neptune with a mass of 23.4 M⊕ and substellar water abundances (XH2O ≈ 0.11, as well as an outer giant planet orbiting exterior to the water-ice line. Our planet formation model encompasses planetary growth through pebble and gas accretion, along with a pebble drift and evaporation module that enables us to track the chemical composition of the disk and the planet over time. We find that the presence of the gas giant is necessary to block water-ice-rich material, resulting in a substellar water content for the inner sub-Neptune, HAT-P-11b. On the other hand, if the giant planet forms too early, not enough solid material can enter the inner disk regions, preventing efficient growth of the inner planet. This highlights the importance of the timing of giant planet formation in explaining the inner system structure, including the formation of Jupiter in our Solar System. Furthermore, our simulations predict a roughly stellar C/O ratio with superstellar C/H and O/H ratios for HAT-P-11b, providing constraints for future observations of this system, which are essential for gaining a more detailed understanding of its formation.
Modeling the molecular gas content and CO-to-H2 conversion factors in low-metallicity star-forming dwarf galaxies

Published: October 2023

Context. Low-metallicity dwarf galaxies often show no or little CO emission, despite the intense star formation observed in local samples. Both simulations and resolved observations indicate that molecular gas in low-metallicity galaxies may reside in small dense clumps, surrounded by a substantial amount of more diffuse gas that is not traced by CO. Constraining the relative importance of CO-bright versus CO-dark H2 star-forming reservoirs is crucial to understanding how star formation proceeds at low metallicity.

Aims. We test classically used single component radiative transfer models and compare their results to those obtained on the assumption of an increasingly complex structure of the interstellar gas, mimicking an inhomogeneous distribution of clouds with various physical properties.

Methods. Using the Bayesian code MULTIGRIS, we computed representative models of the interstellar medium as combinations of several gas components, each with a specific set of physical parameters. We introduced physically motivated models assuming power-law distributions for the density, ionization parameter, and the depth of molecular clouds.

Results. This new modeling framework allows for the simultaneous reproduction of the spectral constraints from the ionized gas, neutral atomic gas, and molecular gas in 18 galaxies from the Dwarf Galaxy Survey. We confirm the presence of a predominantly CO-dark molecular reservoir in low-metallicity galaxies. The predicted total H2 mass is best traced by [C II]158 μm and, to a lesser extent, by [C I] 609 μm, rather than by CO(1–0). We examine the CO-to-H2 conversion factor (αCO) versus metallicity relation and find that its dispersion increases significantly when different geometries of the gas are considered. We define a “clumpiness” parameter that is anti-correlated with [C II]/CO and explains the dispersion of the αCO versus metallicity relation. We find that low-metallicity galaxies with high clumpiness parameters may have αCO values as low as the Galactic value, even at low metallicity.

Conclusions. We identify the clumpiness of molecular gas as a key parameter for understanding variations of geometry-sensitive quantities, such as αCO. This new modeling framework enables the derivation of constraints on the internal cloud distribution of unresolved galaxies, based solely on their integrated spectra.
Leading hadronic contribution to the muon g − 2 from lattice QCD
Authors: Toth B. C.
Published: October 2023

We compute the leading order hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon. The calculations are performed using four flavors of stout smeared staggered quarks, with quark masses at their physical values. The continuum limit is taken using six different lattice spacings ranging from 0.132 fm down to 0.064 fm. All strong isospin breaking and electromagnetic effects are accounted for to leading order. A controlled infinite volume limit is taken thanks to dedicated simulations performed in box sizes up to 11 fm. Putting all these ingredients together, we find [(gµ − 2)/2]LO−HVP = 707.5[5.5] 10−10, which has a total uncertainty of 0.8%. Compared to determinations based on the e+e− → hadrons cross section, our result significantly reduces the tension between the standard model prediction for the muon g − 2 and its experimental value.

L’analyse du comportement d’un système dynamique est proposée dans cette communication. L’objectif est d’amener aux étudiants un ensemble de techniques dont la mise en œuvre est toujours légitimée par un besoin spécifique. La contextualisation de l’apprentissage leur permet de mieux appréhender l’ensemble des compétences mises en jeu et d’acquérir le recul nécessaire à l’application de ces savoir-faire à d’autres thématiques scientifiques. Loin de la posture d’un apprenant passif soumis à une accumulation de compétences qui lui semblent indépendantes les unes des autres, l’étudiant se positionne naturellement dans un environnement pluridisciplinaire. Il nous semble crucial de décloisonner les matières abordées classiquement pendant une formation : ici, pour une même problématique, seront mises en œuvre des compétences en thermique, modélisation, mathématique appliquées, simulation, analyse de données…
Pédagogie en Mode Projet Réel (PMPR)
Authors: Laubin Jean-Marc , Coudoux François-Xavier , Pommeray Michel , Mouren Renan
Published: October 2023

Depuis 11 ans l’INSA Hauts-de-France (Valenciennes – France) a introduit dans ses enseignements de son Master AMINJ (Audiovisuel, Médias Interactifs Numériques et Jeux) une pédagogie innovante qui consiste à faire l’apprentissage de la gestion de projet audiovisuel et multimédia en situation réelle. Après deux années de tâtonnement dans le cadre universitaire classique dans lesquelles les étudiants restaient dans une posture consistant à résoudre des exercices, de nouvelles modalités ont été mises en place en 2012, puis améliorées au fil des ans. Cette approche pédagogique intitulée Pédagogie en Mode Projet Réel (PMPR), consiste à combiner l’enseignement théorique universitaire avec la réalisation par les étudiants en parallèle d’un projet réel porté par une structure associative. Le projet réel se déroule en autonomie vis à vis de l’établissement d’enseignement et ce dans un contexte d’inscription à 360 ° dans le réel avec la nécessité de définir le projet, d’en étudier la faisabilité avec ajustement éventuel, de trouver les partenaires nécessaires, de le financer, de le réaliser dans son intégralité, d’en faire la promotion auprès du public potentiel, et in fine de prouver sa bonne fin par une présentation publique, tout cela en respectant la législation et la réglementation existantes. Sur le plan universitaire les étudiants sont chacun amené à développer une attitude réflexive d’autoobservation des méthodes de gestion de projet mises en œuvre dans le cadre de leur participation au projet réel en tant que membre associatif. C’est ainsi que chacun produit un corpus de documents qui sert de support à l’évaluation universitaire. Cet article décrit en détail le processus mis en œuvre dans la pédagogie PMPR pour atteindre les objectifs pédagogiques et les évaluer. C’est aussi l’occasion de faire un retour d’expérience d’autant que, depuis deux ans, la phase de développement de la pédagogie PMPR est terminée et qu’il s’agit désormais de la mettre en œuvre avec un accompagnement beaucoup plus léger de la part des structures associatives porteuses de projet.

PV panels as a renewable energy source for residential building – An economical comparison before and during the energy crisis
Authors: Brandtner Michal , Sotolar Vaclav , Bohacek Adam , Venkrbec Vaclav
Published: October 2023

The application of renewable energy sources is a current trend today due to the limited sources of fossil. A substantial part of these energy sources is solar radiation. The development of electricity prices was significantly affected by two global crises, the COVID-19 pandemic and the energy crisis associated with the Russia-Ukraine conflict. The essence of the article is to compare the economic sense and appropriateness of investing in a photovoltaic power plant system and its return over time, considering the prediction of the development of electricity prices between 2020 and 2023 and subsequently also with a 15-year price prediction. The article deals with investment, energy consumption and financial evaluation of a PV system with PV panels installed on the ventilated façade of a residential building in the Czech Republic. The conclusions of the article show that the increase in investment in the PV panels themselves between 2020 and 2023 is a crucial factor for the return of the entire system. Predictive models of the development of electricity prices and associated liquidity of the investment also play a significant role in this issue.

Traitement orthodontique-chirurgical : facteur de risque des DTM ?
Authors: Ehrmann Elodie , Bernabeu Marie , Tillier Yannick , Camia Julien , Ecalle Corentin , Savoldelli Charles , Charavet Carole
Published: October 2023

Introduction : les protocoles orthodontiques-chirurgicaux se sont particulièrement développés ces dernières années. Certains patients présentent avant, pendant ou après la chirurgie orthognathique (CO), des troubles articulaires ou musculaires de l’appareil manducateur. Ceux-ci sont regroupés sous le nom de dysfonctionnements temporo-mandibulaires (DTM). Cette revue systématique de la littérature visait à déterminer si de nouvelles études publiées à partir de 2021 ont examiné la relation entre le traitement orthodontique-chirurgical et les DTM.

Matériels et méthodes : une recherche électronique a été effectuée dans la base de données Pudmed, complétée par une recherche manuelle, incluant toute étude publiée après 2021 (date de la dernière recherche issue d’une revue systématique de la littérature sur le sujet) jusqu’à juin 2023 évaluant la prévalence des DTM lors du traitement orthodontique-chirurgical. Le diagnostic de DTM devait être posé à l’aide de l’algorithme diagnostique « diagnostic criteria for temporomandibular disorders (DC/TMD) » et/ou le diagnostic de déplacement discal devait être posé à l’aide de l’imagerie à résonnance magnétique (IRM). Les données ont été extraites et analysées statistiquement.

Résultats : parmi les 100 résultats issus de cette recherche, sept articles éligibles ont été inclus, représentant un total de 548 patients en cours de traitement orthodontique-chirurgical. Les différentes études ont montré des résultats concordants et significatifs en ce qui concerne la réduction des bruits articulaires (64,8 %), des arthralgies (57 à 77 %) et des myalgies (73 à 100 %) après traitement orthodontique-chirurgical. Cependant certains patients révélaient ces signes et symptômes dont ils étaient indemnes avant traitement : 15 % d’entre eux un bruit articulaire, 8,6% une arthralgie et 7,7 % une myalgie. D’autre part, les effets de la CO sur la position discale étaient objectivement imprévisibles. De plus, selon les études qui l’ont exploré, les signes et symptômes de DTM ne semblaient pas liés à la méthode chirurgicale ou à la classe squelettique.

Conclusion : la CO semble avoir un impact positif sur les signes et symptômes de DTM sans qu’il ne soit possible de prévoir les conséquences sur la position du disque de l’ATM qu’il soit initialement en position normale ou déplacé.
Industrial Symbiosis - Recommendations on a business framework conducive for successful Industrial Symbiosis at the Kwinana industrial area
Authors: Oughton Chris , Kurup Biji , Anda Martin , Ho Goen
Published: October 2023

With an extensive presence in the world of Industrial Symbiosis literature, the Kwinana industrial area in Perth, Western Australia is a powerhouse of integrated heavy industrial activity. From when its first entrant arrived in 1955, development has been strong, and now it presents a complex industrial cluster with a wide range of industrial enterprises present, ranging from several major industrial multi-product manufacturers to those filling niche markets. Formal reporting of its economic contribution has occurred periodically over 40 yr, with one of the features of this being a series of four earlier iterations, and in this paper, the fifth, of a schematic diagram that identifies the enterprises engaged in symbiotic relationships and the nature of the associated materials exchanged. While the earlier reports concentrated solely on the traditional materials exchanges, the present study (data collected in 2021) went beyond these to gather additional data on what the authors are proposing as additional dimensions of the traditional Industrial Symbiosis framework. Aspects of Kwinana's skilled workforce, its support industry base, and its overlying governance framework were studied to provide insights into what role they play in explaining why some industrial clusters appear to provide a supportive business environment, and why other clusters struggle to gain momentum. The new study identified that the novel posited dimensions of Industrial Symbiosis are interlinked at the precinct level, and that at the macro (societal) level, they combine to contribute to the effectiveness of the Circular Economy.

Introducción La pandemia producida por el SARS-COV-2 generó menos cirugías traumatológicas a nivel universal. El propósito de este trabajo es determinar la incidencia de fractura de cadera, epidemiología, tiempo de estadía hospitalaria y tasa de resolución quirúrgica en Chile durante el primer año de pandemia.

Material y Métodos Estudio transversal. Se analizó las bases de datos del Departamento de Estadística e Información en Salud (DEIS) de 2019 y 2020, identificando pacientes mayores a 60 años con egresos hospitalarios asociados a códigos de fractura de cadera. La incidencia de fractura de cadera fue calculada usando reportes del Instituto Nacional de Estadística (INE).

Resultados La incidencia de fractura de cadera durante el 2020 fue un 14% menor a la incidencia del 2019, tuvo una correlación moderada con la movilidad del país y una relación inversa a los casos de COVID-19 acumulados mensualmente. La mediana del tiempo de duración de la hospitalización durante el 2020 fue de 8 días (rango intercuartílico, 5 a 14) , lo cual fue significativamente menor (p < 0.0001) que en 2019 (10 días, rango 6 a 16 intercuartílico). La tasa de resolución quirúrgica se mantiene por debajo del 80%.

Conclusiones Las hospitalizaciones por fractura de cadera en Chile disminuyeron durante el primer año de pandemia. Hubo un descenso en la estadía hospitalaria significativo. Sin embargo, la tasa de resolución quirúrgica en fractura de cadera persiste baja.

The increased stiffness of arteries triggers a phenotypic switch, hypermigration, and hyperproliferation of vascular smooth muscle cells (VSMCs), leading to neointimal hyperplasia and accelerated neointima formation. However, the mechanism underlying this trigger remains unknown. Our analyses of whole-transcriptome microarray data from mouse VSMCs cultured on stiff hydrogels simulating arterial pathology identified 623 genes that were significantly and differentially expressed (360 upregulated and 263 downregulated) relative to expression in VSMCs cultured on soft hydrogels. Functional enrichment and gene network analyses revealed that these stiffness-sensitive genes are linked to cell cycle progression and proliferation. Importantly, we found that survivin, an inhibitor of apoptosis protein, mediates stiffness-dependent cell cycle progression and proliferation as determined by gene network and pathway analyses, RT-qPCR, immunoblotting, and cell proliferation assays. Furthermore, we found that inhibition of cell cycle progression did not reduce survivin expression, suggesting that survivin functions as an upstream regulator of cell cycle progression and proliferation in response to ECM stiffness. Mechanistically, we found that the stiffness signal is mechanotransduced via the FAK-E2F1 signaling axis to regulate survivin expression, establishing a regulatory pathway for how the stiffness of the cellular microenvironment affects VSMC behaviors. Overall, our findings indicate that survivin is necessary for VSMC cycling and proliferation and plays a role in regulating stiffness-responsive phenotypes.

We study theoretically the electronic structure of three-dimensional (3D) higher-order topological insulators in the presence of step edges. We numerically find that a 1D conducting state with a helical spin structure, which also has a linear dispersion near the zero energy, emerges at a step edge and on the opposite surface of the step edge. We also find that the 1D helical conducting state on the opposite surface of a step edge emerges when the electron hopping in the direction perpendicular to the step is weak. In other words, the existence of the 1D helical conducting state on the opposite surface of a step edge can be understood by considering an addition of two different-sized independent blocks of 3D higher-order topological insulators. On the other hand, when the electron hopping in the direction perpendicular to the step is strong, the location of the emergent 1D helical conducting state moves from the opposite surface of a step edge to the dip (270° edge) just below the step edge. In this case, the existence at the dip below the step edge can be understood by assigning each surface with a sign (+ or −) of the mass of the surface Dirac fermions. These two physical pictures are connected continuously without the bulk bandgap closing. Our finding paves the way for on-demand creation of 1D helical conducting states from 3D higher-order topological insulators employing experimental processes commonly used in thin-film devices, which could lead to, e.g., a realization of high-density Majorana qubits.

This study investigated the potential of producing and upgrading bio-oil from plastic waste through a catalytic pyrolysis process. Plastic waste samples composed of polystyrene, polyethylene, and low-density polyethylene, shredded to sizes of 1.5–2.5 mm and blended in a ratio of 50/25/25, respectively, were pyrolyzed in a fluidized bed reactor at optimal conditions of 560–650 °C, a heating rate of 15 °C/min, and N2 gas flow rate of 100 ml/min in the presence of zeolite catalysts. The produced bio-oil was treated with fossil diesel, calcium hydroxide, and sodium sulfate to enhance its properties. The results showed that bio-oil production was increased to 65 wt. %, while char was reduced to 3.5 wt. %. Treatment with 20 wt. % diesel reduced bio-oil kinematic viscosity by 58% and improved stability from 20% to 50%. The addition of 16 g calcium hydroxide reduced the bio-oil acidity by 51% from a pH of 3.2–4.85. Furthermore, the bio-oil moisture content was reduced from 10 to 5.2 wt. % through the addition of 10 g of sodium sulfate, while the lower heating value was improved to 39.0 MJ/kg. Therefore, the catalytic pyrolysis of plastic waste in a fluidized bed reactor, and the various treatments performed on the generated bio-oil proved to be an effective technique to enhance the economic value of plastic waste and its environmental management at large.

In this research, two modified forms of the Ḡ≡G′G-expansion method are employed to investigate various kinds of solitary wave solutions that include kink, lump, periodic, and rogue wave solutions within the framework of the fractional coupled Higgs system. The underlying patterns in the targeted model are revealed by using extended and generalized Ḡ-expansion methods. The first step involves converting the model into nonlinear ordinary differential equations via a fractional complex transformation. Following that, the suggested improved versions of the Ḡ-expansion approach are used to provide numerous solitary wave solutions. Some solitary wave solutions are represented by two- and three-dimensional graphs, demonstrating their typical propagating behavior. This research finishes by summarizing the vast findings and exploring their implications for high-energy physics.

Hexagonal Mn3Ge, with both kagome lattice and triangular antiferromagnetism, has gained significant attention due to its large anomalous Hall effect (AHE), resulting from the non-vanishing Berry phase. In this study, we present the magnetic and anomalous transport properties of a series hexagonal D019 type Fe-doped Mn3Ge alloys with the composition of Mn3.1−xFexGe0.9 (x = 1.6, 1.8, 2.0). The ferromagnetic interactions gradually increase with increasing Fe content. The longitudinal resistivity of all alloys exhibits a typical metallic behavior, increasing with temperature from 5 to 390 K. The residual resistivity decreases from 120.4 to 67.8 μΩ·cm as x increases from 1.6 to 2.0. A temperature-driven Lifshitz transition and a spin reorientation have been observed in the x = 1.6 alloy. Topological Hall effect accompanied by the spin reorientation is demonstrated. The maximum value of the topological Hall resistivity ρxyT is approximately 0.16 μΩ·cm. The relationship of ρxyA∝ ρxx in x = 1.6 alloy suggests that the extrinsic skew scattering predominantly contributes to the AHE mechanism. In the case of x = 1.8 and 2.0, both intrinsic and extrinsic factors contribute to the AHE. The anomalous Hall conductivity of our polycrystalline samples at room temperature is comparable to that of single crystal Mn3Ge, which is advantageous for practical applications. This study reveals the effectiveness of chemical engineering in tailoring nontrivial spin textures and the AHE.

The phenomenon of water–jet pump stall can be ascribed to the development of blade boundary layer separation with the transition process playing a significant role in this separation. The hydrofoil is usually used as a simplified model of the water–jet pump impeller blade, and its flow field characteristics have important reference values for analyzing the impeller flow. Based on the transition model and the dynamic mode decomposition method, this article presents the results of a study that was carried out on the stall characteristics of the NACA0009 blunt trailing edge hydrofoil. The transition characteristics of hydrofoil surfaces at different angles of attack (AoA)and Chord-based Reynolds numbers (ReL) are obtained. The hydrofoil boundary layer transition is dominated by natural transition as the AoA is less than 4°, while the transition is dominated by leading-edge separation-induced transition as the AoA is greater than 4°. The investigation yields the dynamic properties of the LSB (Laminar Separation Bubble) as the AoA is varied. The phenomenon known as the deep stall is distinguished by the movement of the stall vortex toward the upstream direction near the trailing-edge region, where it merges with the LSB in the leading-edge region. This phenomenon leads to oscillations in the lift and drag coefficients. The relationship between the LSB and the trailing-edge stall vortex is established using DMD (Dynamic Mode Decomposition) methods. As the phenomenon of the deep stall occurs, it can be observed that the modal energy of the leading-edge LSB is comparatively higher than the modal energy of the trailing-edge stall vortex, inducing the dominant role of the LSB and the movement toward the trailing-edge region and, consequently, the phenomenon of trailing-edge vortex shedding in the hydrofoil. The findings of this study could be guidance for the design of fluid machinery blades.

Electronic dynamics in the excited state of transition-metal dichalcogenides (TMDs) has attracted great interest. To understand the ultrafast intraband scattering process of excited electrons in the conduction band, we demonstrated ultrafast time-resolved electron diffraction measurements with double-optical-pulse excitation and ultrafast transient reflectivity measurements of a TMD material, 2H-MoTe2. Due to the saturable absorption (or Pauli blocking) effect present in 2H-MoTe2, the system does not absorb the second excitation pulse until the excited electrons generated by the first excitation pulse with a specific fluence are scattered in the conduction band. By exploiting the Pauli blocking effect in ultrafast time-resolved electron diffraction measurements with double-optical-pulse excitation, we found that the excited electrons were scattered within 100 fs comparable to the excitation optical pulse duration. Furthermore, the excited electrons were relaxed to the lowest energy level of the conduction band (K- or Σ-valley) within 1–2 ps.
