Published: October 2023

AbstractEmotional labor has been a focal point in occupational well-being literature, but studies have long overlooked an important group of emotional laborers: performers. This research represents a pioneering effort to examine dancers’ adoption of emotional labor strategies, their antecedent of self-consciousness, and the outcome of flow experience. We explored these elements both in the traditional setting of stage dancing and in the novel context of online dance classes without on-site spectators during the COVID-19 pandemic. The results revealed that dancers employed all three common emotional labor strategies: surface acting, deep acting, and expression of naturally felt emotions, with deep acting being the most frequent. In the traditional setting, only the expression of naturally felt emotions mediated the positive effect of private self-consciousness and the negative effect of public self-consciousness on flow experience. In contrast, in the online setting, only private self-consciousness impacted flow through the mediation of deep acting and expression of naturally felt emotions. This exploratory study bridges dramaturgy-originated theories of emotional labor with empirical performing arts research, preliminarily advancing knowledge in the relevant fields of dance education, self-presentation, and flow studies.

AbstractSarcopenia is a progressive loss of muscle mass and strength that is associated with increasing the risk of falls, musculoskeletal diseases, and chronic metabolic diseases. However, the animal models adopted to study sarcopenia face limitations since the functional tests conducted on human cannot be directly adapted to animals because the animals do not follow instructions. Moreover, current preclinical research tools for muscle function assessment, such as the rotarod, grip strength, and treadmill, have limitations, including low-intensity simple movements, evaluator subjectivity, and limited power indicators. Hence, in this study, we present a new jumping-power assessment tool in a preclinical rodent model to demonstrate muscle functions. To overcome the light weight and command issues in the rodent model, we developed an electrical stimulation-assisted jump power assessment device. Precisely, the device utilizes a load cell with a 0.1 g resolution and a 50 points/s data acquisition rate to capture the short period of the mouse jump. Additionally, interdigitated electrodes are used to electrically stimulate the mice and make them jump. While our primary focus in this article is the validation of the newly developed jump power assessment device, it is worth noting that this tool has several potential utilities. These include the phenotypic comparison of sarcopenia models, the exploration of muscle function reduction mechanisms, muscle function-related blood biomarkers, and the evaluation of drug intervention effects.

Published: October 2023

ZusammenfassungMechanische Kreislaufunterstützungssysteme (engl. Mechanical Circulatory Support, MCS) haben in den letzten Jahren eine zunehmende Bedeutung in der akutmedizinischen Therapie des kritisch
kranken Patienten im Schock erlangt. Aktuell stehen in Europa verschiede Systeme zur Verfügung, die sich in Wirkweise und Einsatzgebiet signifikant unterscheiden. Neben den
MCS-Charakteristika und der Zentrumsexpertise sind aber auch Patientencharakteristika für die Auswahl des richtigen MCS zu beachten. Unterschiedliche Schockformen fordern eine differenzierte
Therapie, je nach Ätiologie des Schocks und seiner hämodynamischen Akzentuierung (so braucht z. B. ein infarktbedingter kardiogener Schock mit führendem Linksherzversagen eine andere
Therapie als ein infarktbedingter kardiogener Schock mit führendem Rechtsherzversagen). Die Auswahl des jeweiligen Herzunterstützungssystems richtet sich nach der Pathophysiologie der
zugrunde liegenden Erkrankung. Bisweilen sind Kombinationen von mehreren Unterstützungssystemen erforderlich. Dieser Übersichtsartikel diskutiert die verschiedenen Systeme (extrakorporale
Membranoxygenierung, intraaortale Ballonpumpe, Mikroaxillarpumpe/perkutanes linksventrikuläres Unterstützungssystem, perkutanes rechtsventrikuläres Unterstützungssystem) und deren
Einsatzmöglichkeit im Kontext der verschiedenen Schockformen.

Published: October 2023

Zusammenfassung
Hintergrund Verletzungen des Bewegungsapparats sind häufige
Ereignisse im Sport. Bedürfen Verletzungen des Bewegungsapparats im
Berufssportbereich einer Behandlung, sind neben dem Berufssportler (Patient)
auch die Leistungserbringer (Ärzte, Therapeuten) und
Kostenträger (im Berufs- bzw. Profisport: die Verwaltungs-
Berufsgenossenschaft, VBG) am Verfahren beteiligt. Wird eine operative Therapie
notwendig, stellt die präoperative körperliche
Funktionsfähigkeit einen wichtigen prognostischen Faktor in Bezug auf
den Genesungsprozess dar. In den letzten Jahren hat die
Prähabilitation – d. h. die
präoperative Verbesserung bzw. Verstärkung der
Körperfunktionen zum Erhalt einer patientenindividuell optimalen
Leistungs- und Funktionsfähigkeit nach einer geplanten Operation
– zunehmend an Bedeutung gewonnen.
Fragestellung und Zielsetzung In dieser Arbeit werden erstmals die
Auswirkungen der Prähabilitation am Beispiel der vorderen
Kreuzbandruptur aus Sicht aller Beteiligten dargestellt.
Methodik Wir führten eine systematische Literaturrecherche in
PubMed und Embase durch.
Ergebnisse Von den initialen 1.862 Artikeln mussten 1.858 ausgeschlossen
werden. Nur 2 Metaanalysen erfüllten die Einschlusskriterien. Der
häufigste Ausschlussgrund war die ungenügende Qualität
der Veröffentlichung. Die Studien zeigten, dass Patienten, die eine
Prähabilitation erhielten, postoperativ eine höhere Muskelkraft
und besseren Funktionszustand aufwiesen sowie schneller ihr vorheriges
Leistungsniveau (Return to Play) erreichen konnten. Für die
Physiotherapeuten ergab die Prähabilitation einen finanziellen Mehrwert
(994.85 €), sofern die Vergütung der postoperativen
Rehabilitation dadurch nicht gemindert wurde. Für den
Unfallversicherungsträger bedeutete die kürzere Erholungsphase
Kosteneinsparungen durch Verringerung des Verletztengeldes (14.933 € bei
einer Einsparung von 8 Wochen), wenn dadurch das Risiko für erneute oder
Folgeverletzungen nicht steigt.
Diskussion Die Prähabilitation zeigte einen positiven Nutzen
für alle Beteiligten. Sie dient dem Patienten dazu, die
Funktionsfähigkeit zu verbessern und ggf. den Zeitraum bis zur Operation
zu verkürzen. Für den Unfallversicherungsträger stehen
den geringen Kosten der Prähabilitation Einsparmöglichkeiten
gegenüber. Es ist wichtig, die in dieser Arbeit festgestellten positiven
Auswirkungen der Prähabilitation in weiteren Arbeiten zur systematischen
Anwendung der Prähabilitation im deutschen Gesundheitssystem zu
prüfen.
Fazit Bei der Prähabilitation handelt es sich um ein
wissenschaftlich vernachlässigtes Forschungsthema. Die vorliegende
Arbeit stellt (beispielhaft anhand der VKBR) erstmalig ihren Nutzen für
alle Beteiligten (Versicherte bzw. Patienten, Physiotherapeuten und
Versicherungsträger) dar. Die aktuelle Studienlage reicht nicht aus, um
die systematische Anwendung der Prähabilitation im deutschen
Gesundheitssystem zu empfehlen.
Radiographic Edema Is a Predictor of de Quervain's Tenosynovitis

Published: October 2023

Abstract
Background de Quervain's tenosynovitis (DeQ) is a clinical diagnosis; however, due to the symptom overlap with other pathologies, it can occasionally be challenging to make an accurate diagnosis, especially for nonorthopaedic trained physicians.
Questions/Purposes We hypothesized that the ratio of radial-sided to ulnar-sided soft tissue swelling could serve as a universally accessible diagnostic tool to assist in differentiating DeQ from other upper extremity conditions.
Patients and Methods We retrospectively identified patients with isolated DeQ (M65.4), thumb carpometacarpal arthritis (M18.X), or carpal tunnel syndrome (G56.0x) between 2018 and 2019. Five blinded, independent reviewers evaluated anterior–posterior radiographs of the affected wrist. A digital caliper was used to measure the shortest distance from the lateral cortex of the distal radius and the medial cortex of the distal ulna to the outer edge of the radial and ulnar soft tissue shadows, respectively.
Results The mean radial:ulnar ratio in the DeQ group was significantly larger than in the control groups. The interclass correlation coefficient showed strong agreement between all measurements. Patients with a radial:ulnar ratio of 1.7 or higher had a 61% chance of having DeQ with a 56.5% sensitivity, 66.3% specificity, 59.3% positive predictive value (PPV), and 63.8% negative predictive value. A ratio of more than 2.5 correlates to a 55% chance of having DeQ with a sensitivity of 12.9%, specificity of 96.9%, and PPV of 78.6%.
Conclusion The ratio of radial- to ulnar-sided wrist edema can be used as a novel diagnostic aid in DeQ, especially for those not trained in orthopaedics or hand surgery.
Level of Evidence Level IV, diagnostic study.
Platelet Contributions to the (Pre)metastatic Tumor Microenvironment
Authors: Roweth Harvey G. 
Published: October 2023

AbstractAlongside their conventional roles in thrombosis and hemostasis, platelets have long been associated with nonhemostatic pathologies, including tumor cell metastasis. Numerous mechanistic studies have since demonstrated that the direct binding of platelets to intravascular tumor cells promotes key hallmarks of metastasis, including survival in circulation and tumor cell arrest at secondary sites. However, platelets also interact with nonmalignant cells that make up the stromal and immune compartments within both primary and metastatic tumors. This review will first provide a brief historical perspective on platelet contributions to metastatic disease before discussing the emerging roles that platelets play in creating microenvironments that likely support successful tumor cell metastasis.
Effect of source–drain contact and channel length on the performance of vertical thin-film transistors
Authors: Yin Xue-Mei , Lin De-Lang , Yan Yu-Pei , Li Yi , Ma Wei-Min 
Published: October 2023

Vertical thin-film transistors (V-TFTs) with an InSnO-stabilized ZnO channel were fabricated. The vertical architecture enables devices with submicron channel lengths (≤500 nm) to afford delivering drain current greatly exceeding that of conventional planar TFTs. Due to the submicron length of the V-TFT channel, an on/off state current higher than 107 can be achieved even with a drain voltage of 0.01 V, and the subthreshold swing was kept in the tens of mV/dec range owing to the efficacious device preparation. In order to understand the influence of structures on the device performance, the source–drain (S/D) contact and the channel length of V-TFTs were designed and studied. The results show that the increase in the contact area between the active layer and the S/D region can reduce the S/D contact resistance, thus affecting the drain current across the threshold region. When the channel length is shortened to a deep submicron size, the electrostatic coupling between the source and drain electrodes will lead to a decrease in the S/D barrier. This leads to the leakage-induced barrier reduction effect of V-TFTs.
Constraining the Orbital Inclination and Companion Properties of Three Black Widow Pulsars Detected by FAST

Published: October 2023

Abstract
Black widows (BWs) are millisecond pulsars ablating their companion stars. The out-flowing material from the companion can block the radio emission of the pulsar, resulting in eclipses. In this paper, we construct a model for the radio eclipse by calculating the geometry of the bow shock between the winds of the pulsar and companion, where the shock shapes the eclipsing medium but had not been described in detail in previous works. The model is further used to explain the variations of the flux density and dispersion measure of three BW pulsars (i.e., PSR B1957+20, J2055+3829, and J2051−0827) detected by the Five-hundred-meter Aperture Spherical radio Telescope. Consequently, we constrained the parameters of the three BW systems such as the inclination angles and true anomalies of the observer as well as the mass-loss rates and wind velocity of the companion stars. With the help of these constraints, it is expected that magnetic fields of companion stars and even masses of pulsars could further be determined as some extra observation can be achieved in the future.
On the Nature of Long Period Radio Pulsar GPM J1839-10: Death Line and Pulse Width
Authors: Tong H. 
Published: October 2023

Abstract
Recently another long period radio pulsar GPM J1839−10 has been reported, similar to GLEAM-X J162759.5−523504.3. Previously, the energy budget and rotational evolution of long period radio pulsars had been considered. This time, the death line and pulse width for neutron star and white dwarf pulsars are investigated. The pulse width is included as the second criterion for neutron star and white dwarf pulsars. It is found that: (1) PSR J0250+5854 and PSR J0901−4046 etc. should be normal radio pulsars. They have narrow pulse width and they lie near the radio emission death line. (2) The two long period radio pulsars GLEAM-X J162759.5−523504.3 and GPM J1839−10 are unlikely to be normal radio pulsars. Their possible pulse width is relatively large. They lie far below the fiducial death line on the

diagram. (3) GLEAM-X J162759.5−523504.3 and GPM J1839−10 may be magnetars or white dwarf radio pulsars. At present, there are many parameters and uncertainties in both of these possibilities.
Simulation-based study of noise, vibration, and harness of BLDC motor for energy level variation with frequency
Authors: Kardile Balasaheb Annasaheb , Pathan Khizar Ahmed 
Published: October 2023

Abstract
The energy spectrum measurements in noise, vibration, and harness analysis with power spectrum response is a very ancient concept. The work and energy approaches for analyzing Noise, Vibration, and Harmonics (NVH) features are increasing rapidly in recent years. The primary focus is on evaluating imparted energy due to the NVH using an FFT spectrum against the input energy in motors. The simulation depicts the input energy spectra of the kinetic energy, absorbed energy, and dissipated energy very clearly. Earlier the smoothed Fourier amplitude spectrum approach was used for plotting the energy dissipation due to the NVH effect. However, most of the part of accountable energy goes to waste with noise, vibration, and harmonics generated due to harness in motor design. This experiment is conducted in support of Sir Nikola Tesla’s statement “If you wish to understand the universe think in terms of energy, frequency, and vibration”. The ripples an induced in phase current because of the step change of the speed. The predominant frequency in phase current waveform creates the collapsing vibratory waves that create the sound. Sound frequencies above 20 dB are considered unwanted sound known as noise. The energy level variation with NVH influence in BLDCM is measurable for its performance analysis. This research can be further enhanced by designing NVH-free BLDC motors.
Parallel evolution of the G protein-coupled receptor GrlG and the loss of fruiting body formation in the social amoeba Dictyostelium discoideum evolved under low relatedness

Published: October 2023

Abstract
Aggregative multicellularity relies on cooperation among formerly independent cells to form a multicellular body. Previous work with Dictyostelium discoideum showed that experimental evolution under low relatedness profoundly decreased cooperation, as indicated by the loss of fruiting body formation in many clones and an increase of cheaters that contribute proportionally more to spores than to the dead stalk. Using whole-genome sequencing and variant analysis of these lines, we identified 38 single nucleotide polymorphisms in 29 genes. Each gene had 1 variant except for grlG (encoding a G protein-coupled receptor), which had 10 unique SNPs and 5 structural variants. Variants in the 5′ half of grlG—the region encoding the signal peptide and the extracellular binding domain—were significantly associated with the loss of fruiting body formation; the association was not significant in the 3′ half of the gene. These results suggest that the loss of grlG was adaptive under low relatedness and that at least the 5′ half of the gene is important for cooperation and multicellular development. This is surprising given some previous evidence that grlG encodes a folate receptor involved in predation, which occurs only during the single-celled stage. However, non-fruiting mutants showed little increase in a parallel evolution experiment where the multicellular stage was prevented from happening. This shows that non-fruiting mutants are not generally selected by any predation advantage but rather by something—likely cheating—during the multicellular stage.

Abstract
In the decades since the first cannabinoids were identified by scientists, research has focused almost exclusively on the function and capacity of cannabinoids as medicines and intoxicants for humans and other vertebrates. Very little is known about the adaptive value of cannabinoid production, though several hypotheses have been proposed including protection from ultraviolet radiation, pathogens, and herbivores. To test the prediction that genotypes with greater concentrations of cannabinoids will have reduced herbivory, a segregating F2 population of Cannabis sativa was leveraged to conduct lab- and field-based bioassays investigating the function of cannabinoids in mediating interactions with chewing herbivores. In the field, foliar cannabinoid concentration was inversely correlated with chewing herbivore damage. On detached leaves, Trichoplusia ni larvae consumed less leaf area and grew less when feeding on leaves with greater concentrations of cannabinoids. Scanning electron and light microscopy were used to characterize variation in glandular trichome morphology. Cannabinoid-free genotypes had trichomes that appeared collapsed. To isolate cannabinoids from confounding factors, artificial insect diet was amended with cannabinoids in a range of physiologically relevant concentrations. Larvae grew less and had lower rates of survival as cannabinoid concentration increased. These results support the hypothesis that cannabinoids function in defense against chewing herbivores.
A Priori Estimates for Finite-Energy Sign-Changing Blowing-Up Solutions of Critical Elliptic Equations
Authors: Premoselli Bruno 
Published: October 2023

Abstract
We prove sharp pointwise blow-up estimates for finite-energy sign-changing solutions of critical equations of Schrödinger–Yamabe type on a closed Riemannian manifold $(M,g)$ of dimension $n \ge 3$. This is a generalisation of the so-called $C^{0}$-theory for positive solutions of Schrödinger–Yamabe-type equations. To deal with the sign-changing case, we develop a method of proof that combines an a priori bubble-tree analysis with a finite-dimensional reduction, and reduces the proof to obtaining sharp a priori blow-up estimates for a linear problem.
The influence of habitat conditions on abundance and selected individual traits of Arum alpinum in the communities Populetum albae and Tilio cordatae–Carpinetum betuli (Western Carpathians)
Authors: Wójcik Tomasz , Kostrakiewicz-Gierałt Kinga 
Published: October 2023

Abstract
Studies of selected habitat conditions, as well as spatiotemporal variability of the number and selected traits of individuals of the species Arum alpinum were carried out in 2020–2021 in the foothills of the Western Carpathians. The investigations were conducted in permanent patches located in the Golesz nature reserve (Patch I), near the village of Markowce (Patch II), in the Kozigarb nature reserve (Patch III), and near the village of Żółków (Patch IV). Patches I and III were established in a Tilio cordatae–Carpinetum betuli oak–hornbeam forest with undergrowth dominated by low-growth vegetation with narrow leaves, whereas Patches II and IV were established in a Populetum albae riparian forest with undergrowth dominated by broad-leaved species. The most abundant population of A. alpinum was noted in Patch I, but substantial numbers of both vegetative and reproductive individuals were also present in Patches II and IV. The occurrence of temporal variability of individual traits increased from its lowest level in Patch IV, through Patches I and II, to its highest level in Patch III. The significant positive correlation in all populations between length of petioles and blade dimensions, as well as between length of generative stems and infructescence traits confirmed previous findings. Moreover, we showed that A. alpinum was not closely affiliated with a specific forest community. Significant shading and moist nutrient-rich soils are suitable for this species, while dry soils and excessive insolation may limit the flowering and fruiting of individuals.
