Published: July 2023

Abstract
Objective To investigate the impact of sleep quality on postural control in teachers.
Methods Cross-sectional study with 41 schoolteachers (mean age 45.7 ± 10.4 years). Sleep quality was assessed in two ways: objectively (through actigraphy), and subjectively (through the Pittsburgh Sleep Quality Index). Postural control was assessed in an upright posture during 3 trials of 30s (bipedal and semitandem stances in rigid and foam surfaces with eyes open) with a period of rest across trials, on a force platform, based in the center of pressure measurements in the anteroposterior and mediolateral directions.
Results The prevalence of poor sleep quality in this study sample was 53.7% (n = 22). No differences were found between Poor and Good sleep in the posturographic parameters (p > 0.05). Although, there was moderate correlation between postural control in the semitandem stance and subjective sleep efficiency for center of pressure area (rs = -0.424; p = 0.006) and amplitude in anteroposterior direction (rs = -0.386; p = 0.013).
Discussion There is correlation between poor sleep quality and postural control in schoolteachers, as sleep efficiency decreases, postural sway increases. Poor sleep quality and postural control were investigated in other populations, but not in teachers. Several factors such as work overload, insufficient time for physical activities, among others, can contribute to a worse perception of sleep quality, as well as deterioration in postural control. Further studies with larger populations are needed to confirm these findings.

Abstract
Introduction: This study aimed to evaluate the sleep quality and the Social Jetlag frequency in young adults during social distancing because of COVID-19.
Methods: This is a cross-sectional study with 308 students aged ≥18 years and with Internet access. Questionnaires used: Pittsburgh Sleep Quality Index – Brazil (PSQI-BR), Epworth Sleepiness Scale, and Munich Chronotype Questionnaire.
Results: The mean age of the students was 21 ± 3 years (17 - 42y), with no statistically significant difference between genders. The PSQI-BR indicated that 257 (83.4%) had poor sleep quality. The mean of Social Jetlag for young adults was 02:00 ± 01:49h, and we observed that 16.6% (n = 51) had Social Jetlag. Compared to men in the good sleep quality group, women had higher means for sleep duration on study days and free days, mid-point of sleep on study days and free days and corrected mid-point of sleep on free days. However, when compared to men in the group of poor sleep quality, we observed higher means for women regarding sleep duration on study days, the mid-point of sleep on study days, and the corrected mid-point of sleep on free days.
Conclusions: Thus, the high frequency of young adult students who had poor sleep quality associated with Social Jetlag (2 hours) in the present study may reflect a pattern of sleep irregularity, which may be associated with impairment of environmental synchronizers and stimulation of social synchronizers during the lockdown resulting from the COVID-19 pandemic.

Abstract
Objective To investigate sleep duration and its associated factors in adolescents aged 11 years from the 2004 Pelotas (Brazil) Birth Cohort Study.
Methods Sleep duration was assessed using a self-report sleep habits. Independent variables included perinatal, sociodemographic, behavioral, and health characteristics. The associations were estimated using multiple linear regression.
Results The mean sleep duration of 3,179 adolescents was 9.3 hour (SD =1.7 hour). Longer sleep duration was associated with lower socioeconomic status at birth (β: 0.37, 95% CI: 0.12; 0.61), lower mother's education level (p < 0.001), and being female (β: 0.19, 95% CI: 0.06; 0.33). Shorter sleep duration was associated with cesarean section delivery (β: −0.16, 95% CI: −0.31; -0.02); having classes in the morning shift (β: −1.38, 95% CI: −1.51; -1.26), and lower terciles of physical activity (p = 0.04).
Conclusions The mean sleep duration observed in this study was consistent with the international recommendations for this age range. Adolescents from lower income families, who are more active, study in shifts other than morning, girls, and those born through vaginal delivery presented higher sleep duration than their counterparts.

Published: July 2023

Abstract
Objective Amantadine has both anti-glutamatergic and dopaminergic action and may improve restless legs syndrome (RLS). We compared the efficacy and adverse-effect profile of amantadine and ropinirole in RLS.
Methods In this randomized, open-label, 12-week flexible-dose exploratory study, RLS patients with international RLS study group severity scale score (IRLSS) > 10 were randomized to receive either amantadine(100-300mg/day) or ropinirole (0.5-2mg/day). Drug dose was increased until week-6 if IRLSS failed to improve by ≥10% of previous visit score. IRLSS change from baseline at week-12 was the primary outcome. Secondary outcomes included change in RLS-related quality of life (RLS-QOL) and insomnia severity index (ISI), along with clinical-global-impression of change/improvement (CGI-I), and proportion of patients with adverse-effects and resulting discontinuation.
Results Twenty-four patients received amantadine and 22 received ropinirole. Both groups had a significant effect for visit*treatment arm (F (2.19,68.15) =4.35;P = 0.01). With a similar baseline IRLSS, both intention-to-treat (ITT) and per-protocol analyses revealed comparable IRLSS until week-8, with ropinirole appearing superior from week-10 to week-12 (week-12 IRLSS, amantadine vs ropinirole:17.0 ±  5.7 vs 9.0 ±  4.4;P < 0.001). ITT analysis at week-12 showed comparable proportion of responders (≥10% IRLSS reduction) in both groups (P = 0.10). Both drugs improved sleep and QOL, but week-12 scores favoured ropinirole [(ISI:14.4 ±  5.7 vs 9.4 ±  4.5; P = 0.001) ;(RLS-QOL:70.4 ±  17.9 vs 86.5 ±  9.8; P = 0.005)]. CGI-I at week-12 favoured ropinirole (Mann-Whitney U = 35.50, S. E = 23.05;P = 0.01). Four patients in amantadine and two in ropinirole group developed adverse effects, with resulting discontinuation in two patients on amantadine.
Conclusions The present study reports equivalent reduction in RLS symptoms with both amantadine and ropinirole until week-8, with the latter being superior from week-10 onwards. Ropinirole was better tolerated.
Association between 5-Hydroxytryptamine Receptor 2A Gene (rs6313 and rs4941573) Polymorphism and Sleep Bruxism: A Meta-analysis

AbstractGenetic factors may influence sleep bruxism's pathogenesis. Even though the association between the, 5-hydroxytryptamine 2A (5-HTR2A) serotonin receptor gene polymorphism and sleep bruxism has been investigated, inconsistent findings have been discovered. As a result, meta-analysis was performed to gather complete results on this topic. PubMed, Web of Science, Embase, and Scopus databases were searched for all papers containing English abstracts until April 2022. Medical Subject Heading (MESH) terms plus unrestricted keywords were used in the searches. The Cochrane test and the I2 statistic were used to determine the heterogeneity percentage in numerous researches. Comprehensive Meta-analysis v.2.0 software was used to conduct the analyses. Five properly fitting papers were chosen for meta-analysis from the 39 articles acquired during the initial search. The meta-analysis revealed that the 5-HTR2A polymorphism has no link with sleep bruxism susceptibility across the models studied (P-Value > 0.05). The combined odds ratio analysis revealed no statistically significant association between the 5-HTR2A gene polymorphism with sleep bruxism. Nonetheless, these findings require confirmation through researches with large sample sizes. Identifying genetic markers for sleep bruxism may help clarify and expand our current knowledge of bruxism physiopathology.
How can algorithms help in segmenting users and customers? A systematic review and research agenda for algorithmic customer segmentation

Published: July 2023

AbstractWhat algorithm to choose for customer segmentation? Should you use one algorithm or many? How many customer segments should you create? How to evaluate the results? In this research, we carry out a systematic literature review to address such central questions in customer segmentation research and practice. The results from extracting information from 172 relevant articles show that algorithmic customer segmentation is the predominant approach for customer segmentation. We found researchers employing 46 different algorithms and 14 different evaluation metrics. For the algorithms, K-means clustering is the most employed. For the metrics, separation-focused metrics are slightly more prevalent than statistics-focused metrics. However, extant studies rarely use domain experts in evaluating the outcomes. Out of the 169 studies that provided details about hyperparameters, more than four out of five used segment size as their only hyperparameter. Typically, studies generate four segments, although the maximum number rarely exceeds twenty, and in most cases, is less than ten. Based on these findings, we propose seven key goals and three practical implications to enhance customer segmentation research and application.
The impact of venture capital on Chinese SMEs’ sustainable development: a focus on early-stage and professional characteristics
Authors: Liu Lili , Jiang Heng , Zhang Yonglin 
Published: July 2023

AbstractVenture capital is an essential financing option for small and medium-sized enterprises, especially high-tech enterprises. The sustainable development of enterprises is of great significance for promoting the high-quality growth of the economy. In this paper, Chinese-listed companies supported by venture capital from 2002 to 2022 are taken as the research sample. Semiparametric and nonparametric methods are adopted to explore the long-term impact of venture capital on the sustainable development of Chinese enterprises. It is found that the early stage of venture capital companies has a significant promoting effect on the sustainable development of the enterprises. In contrast, professionalism has no significant impact on the sustainable development of enterprises in the short term but has an inhibitory effect in the long term. The results show that venture capital is conducive to enterprises’ standardization and long-term development because it provides funds, supervision, and other noncapital value-added services, such as networking resources, management experience, and market information. Venture capital should refrain from interfering excessively in decision-making in professional and technical fields. This paper addresses the need to research venture capital’s impact on enterprises’ sustainable development. It provides a specific reference for formulating venture capital contracts and related policy recommendations.
Le lexique du wen (culture) dans le discours
politique chinois et dans sa traduction française au prisme de la
textométrie
Authors: Elbaz Pascale , Miao Jun 
Published: July 2023

Résumé
La langue du politique est constituée de cristallisations
linguistiques et sociologiques spécifiques. Elle devient problématique une fois
traduite, car les termes et les syntagmes changent de contexte
géo-socio-culturel. Notre recherche s’oriente sur l’environnement contextuel des
termes concernant la culture et leur articulation dans le
rapport présenté lors de l’ouverture du 19e congrès du Parti
communiste chinois en 2017. En plus d’une attention particulière portée à la
stabilisation des formes langagières, depuis certains stéréotypes lexicaux
jusqu’à des habitus discursifs et notamment la présence de parallélismes, nous
étudions de près la créativité langagière, les difficultés de traduction et
leurs solutions dans un corpus parallèle français-chinois, assistées par des outils
textométriques. Une comparaison contrastive des spécificités de co-occurrences
thématiques autour de la culture entre le français et le chinois permet
d’éclairer les mécanismes d’émergence du langage politique chinois et fournit
également un accès privilégié aux contenus sociaux. En outre, les fonctions
textométriques de groupes de termes, de segments répétés et d’affichage
contextuel donnent un éclairage utile sur le discours programmatif autour de la
culture : culture socialiste avancée, culture socialiste à la chinoise,
confiance culturelle, softpower culturel, etc. Les résultats
obtenus et les méthodes textométriques appliquées peuvent être utiles à toute
analyse de terminologie ou à tout apprentissage de la traduction en langue de
spécialité.
Foreignness as a border-crossing challenge
Authors: Chen Yi-Chiao 
Published: July 2023

Abstract
Based on the concepts of foreignness delineated by theorists in border studies and cultural translation, this
paper analyzes Xi Ni Er’s short stories and identifies two types of translation challenges: the untranslatability of words and the
untransferability of feelings. The Singapore-specific linguistic landscape features heteroglossia and homophonic implications, and
these characteristics constitute untranslatable linguistic foreignness. In addition, this paper notes social and cultural
foreignness that serve the function of making readers feel what the writer feels (e.g., sorrow, nostalgia, and indignation), and
it is difficult to find an effective and suitable translation strategy to trigger empathy among target readers who do not share
social or cultural experiences. This paper, thus, emphasizes the importance of investigating the transference of feelings, and a
survey is conducted to gain reader-based insight into the suitability of offering supplementary materials in translation. Finally,
the results reveal that readers find these materials helpful and not intrusive.

Résumé
Avec la réémergence de la Chine sur la scène internationale, la diffusion de sa production culturelle moderne
devient d’actualité, notamment en Occident où elle est sans doute le moins bien connue. Le présent article se penche sur la
traduction française d’ouvrages de sociologie chinois entre 1949 et 2020 pour en observer la situation globale et les critères de
sélection établis par les éditeurs français. Nous constatons que cette traduction est dans l’ensemble extrêmement atone. Le peu de
travaux qui ont réussi à s’introduire sur le marché français réconcilient en général l’universel et le particulier. Est entre
autres appréciée la production de la première moitié du XXe siècle qui élabore des théories originales à partir d’une
perspective comparatiste.
An interplay between optical rectification and transient photocurrent effect on THz pulse generation from bulk MoS2 layered crystal
Authors: Dhakar Neetesh , Kumar Sandeep , Nivedan Anand , Kumar Sunil 
Published: July 2023

Abstract
Development of novel schemes for efficient terahertz (THz) generation from transition metal dichalcogenides are useful for realizing integrated THz devices based on them and also, understanding of the related fundamental processes from such studies will guide to suitable designs. Here, we report the THz emission efficiency of bulk MoS2 layered crystal at varying femtosecond excitation wavelengths, from 550 nm to the telecommunication wavelength of 1550 nm. By using both the below bandgap excitation at longer wavelengths and the above bandgap excitation at shorter wavelengths, we resolve THz emission contributions from resonant and non-resonant optical rectification (OR) processes, and the surface field induced transient photocurrent effect (TPE). A relatively much larger contribution to THz emission from the TPE than the resonant OR is measured for the above bandgap excitation. We have measured a clear difference between the resonant and nonresonant OR processes. The pure OR part is exclusively determined from detailed experiments using excitation intensity, polarization angle, and azimuthal angle dependent measurements. For the above bandgap excitation, the THz emission gets highly saturated with the increasing excitation intensity. Also, the value of the saturation intensity increases (decreases) with the excitation photon energy (wavelength). Interestingly, we find that the linear polarization angle and the azimuthal angle dependent THz signal due to resonant OR is π/2 phase offset relative to that due to the nonresonant OR.

Calcium, potassium, nitrogen, magnesium, and phosphorus, the main elements of the nutrient solution, are absorbed by plants and play an important role in plants. By measuring Ca2+, K+, Mg2+, NH4
+, NO3
−, HPO4
2−, the artificial neural networks (ANNs) were used in this study to accurately calculate the concentrations of these elements. Firstly, the error sources of the calculating element concentration were analyzed based on the data of six-ion measurement experiments. Subsequently, various optimization algorithms were compared to optimize back propagation and radial basis function ANNs. Finally, the results of mean relative errors (MREs) and recovery values show that ANNs can effectively reduce the measurement error of ion sensors. From the perspective of recovery values, the prediction error of all elements can be controlled within 15%. From the perspective of MRE, except for magnesium and phosphorus elements, the improved model prediction errors of other elements were also less than 10%.

Published: July 2023

Abstract
Nowadays, the search for renewable and sustainable energies is a global concern worldwide. In this regard, extensive studies are devoted to inorganic perovskites; nonetheless, the latter suffers from several drawbacks, such as lead toxicity. In this paper, structural stability, optoelectronics and thermoelectric characteristics of double perovskites (DPs) Rb/Cs2ScAuI6 have been systematically explained. The phonon dispersion is evaluated for structural existence, and the formation energy is determined to confirm thermodynamic stability. In addition, the elastic constants fulfilled the Born stability criteria, and Pugh’s ratio (B/G) confirms the ductile nature of studied DPs. The obtained results for electronic characteristics of Rb/Cs2ScAuI6 using mBJ+SOC and HSE06 show that the indirect bandgap nature has bandgap values 1.40/1.95 eV and 1.36/1.90 eV, respectively. Further, optical characteristics of DPs have been investigated in terms of dielectric function up to incident photon energy 0–12 eV. Besides, the transport behavior in terms of temperature, carrier concentration, and chemical potential calculated using the BoltzTrap code indicates that both DPs low thermal conductivity, high electrical conductivity, and high Seebeck coefficient.

Published: July 2023

Abstract
A theoretical model of the interaction between inter-modal four-wave mixing (IMFWM) and stimulated Raman scattering (SRS) in continuous high-power fiber lasers is proposed. The investigation shows that the combined gain of IMFWM and SRS is affected by mode combinations and fiber parameters. The dynamic evolution of the enhanced IMFWM suppressing the SRS is observed in the output spectra, accompanied by the intensity asymmetry of the IMFWM-induced Stokes and anti-Stokes lights. Furthermore, the substantial suppression of the combined gain was realized by increasing the coiling diameter of the gain fiber from 130 mm to 150 mm under mode combination (21,01 → 21,01)-dominated IMFWM.
Direction-of-arrival estimation for acoustic signals based on direction-dependent parameter tuning of a bioinspired binaural coupling system
Authors: Jünemann Philipp , Schneider Axel , Waßmuth Joachim 
Published: July 2023

Abstract
Bioinspired methods for sound source localization offer opportunities for resource reduction as well as concurrent performance improvement in contrast to conventional techniques. Usually, sound source localization requires a large number of microphones arranged in irregular geometries, and thus has high resource requirements in terms of space and data processing. Motivated by biology and using digital signal processing methods, an approach that adapts the coupled hearing system of the fly Ormia ochracea with a minimally distant two-microphone array is presented. Despite its physiology, the fly is able to overcome physical limitations in localizing low-frequency sound sources. By exploiting the filtering effect of the coupling system, the direction-of-arrival of the sound is determined with two microphones at an intermediate distance of 0.06 m. For conventional beamforming algorithms, these physical limitations would result in degraded localization performance. In this work, the bioinspired coupling system is analyzed and subsequently parameterized direction-sensitive for different directions of incidence of the sound. For the parameterization, an optimization method is presented which can be adopted for excitation with plane as well as spherical sound wave propagation. Finally, the method was assessed using simulated and measured data. For 90% of the simulated scenarios, the correct direction of incidence could be determined with an accuracy of less than 1∘ despite the use of a minimal distant two-microphone array. The experiments with measured data also resulted in a correct determination of the direction of incidence, which qualifies the bioinspired method for practical use in digital hardware systems.
Sharing EPR steering between sequential pairs of observers

Published: July 2023

Abstract
The recycling of quantum correlations has attracted widespread attention both theoretically and experimentally. Previous works show that bilateral sharing of nonlocality is impossible under mild measurement strategy and 2-qubit entangled state can be used to witness entanglement arbitrary many times by sequential and independent pairs of observers. However, less is known about the bilateral sharing of EPR steering yet. Here, we aim at investigating the EPR steering sharing between sequential pairs of observers. We show that an unbounded number of sequential Alice-Bob pairs can share the EPR steering as long as the initially shared state is an entangled two-qubit pure state. The claim is also true for particular class of mixed entangled states.
