Authors: Zhou Dejun , Zhuang Youchao , Sheng Zuntian 
Published: January 2023

Abstract
Many coumarin derivatives have good biological activity and application value in fluorescent probes. Therefore, synthetic routes to coumarin derivatives have also attracted the attention of many research groups. In this work, based on the Pechmann coumarin synthesis method, the influence of various Lewis acids on the reaction was discussed, and the optimal synthesis conditions of 7-hydroxy-4-substituted coumarins were explored. Based on the experimental results, a possible mechanism was proposed, which provides a reference for future industrialized production of coumarins.

Abstract
Vocabulary is a key variable to successful listening comprehension. Research has explored the relationship between aural and orthographic vocabularies and listening comprehension. This current study examined the relationships among aural vocabulary, orthographic vocabulary, and listening comprehension within the same Japanese cohort in an integrated manner. The test data of 155 Japanese EFL students, who took identical aural and orthographic vocabulary tests (the listening vocabulary levels test [LVLT] and new vocabulary levels test [NVLT], respectively) and a high-stakes listening test (Test of English for International Communication (TOEIC) for Parts I and II), were analyzed. The results indicated that aural and orthographic vocabulary are closely related but not identical. Moreover, orthographic vocabulary is more connected to the word- and propositional-level understanding of extended texts than to aural vocabulary for the Japanese group. More specifically, the 2,000-word and 4,000-word level and the academic vocabulary of the orthographic vocabulary predicted 27% of the variance of the listening comprehension test performance, whereas only the academic words of the aural vocabulary predicted 8%.
Broadband spin-multiplexed single-celled metasurface holograms: a comprehensive comparison between different strategies
Authors: im Sande Sören , Bozhevolnyi Sergey I. , Ding Fei 
Published: January 2023

Abstract
Metasurface-generated holograms have emerged as a unique platform for arbitrarily shaping the reflected/transmitted wavefronts with the advantages of subwavelength large pixel sizes and multiple information channels. However, achieving multiple holographic images with large operation bandwidths is a rather complicated and arduous issue due to the dissimilar dispersion of all meta-atoms involved. In this work, we design and experimentally demonstrate single-celled metasurfaces to realize broadband and spin-multiplexed holograms, whose phase modulation is based only on the geometric phase supplied by a judiciously designed high-performance nanoscale half-wave plate operating in reflection. Four different multiplexing strategies are implemented, and the resulting holograms are systemically assessed and compared with respect to background levels, image fidelities, holograms efficiencies, and polarization conversion ratios. Our work complements the methodologies available for designing multiplexed meta-holograms with versatile functionalities.

Abstract
Ash and slag waste accumulated throughout the world in appreciable amounts are, in essence, man-made deposits and are of interest as a potential source of critical elements, in particular Sc, as well as raw materials for obtaining construction materials. Coals from Siberia and the Far East are used as fuel at thermal power plants (TPPs) in the Primorsky Territory of Russia. These coals are characterized by a high Sc content. The content of Sc in the ash and slag wastes from landfills of six TPPs in Primorsky Krai was determined by neutron activation analysis with a Cf-252 radionuclide source. The Sc content ranged from 5.1 to 52.7 ppm. Average concentrations of Sc in ash and slag waste are 23.3 ppm. Verification of the INAA method was carried out by comparing with the ICP-MS data in reference materials (laterite and carbonatite scandium-containing ores). The possibility of using the Sc-46 isotope, produced by thermal neutron activation, as a radioactive tracer to assess the effectiveness of operations for Sc extraction and concentration is shown. Sc has been preconcentrated from the initial ash of the Primorsky thermal power plant by the precipitation method in the form of hydroxide, followed by separation from accompanying elements by dissolving the hydroxide in sodium hydroxide or hydrochloric acid. The possibility of concentrating Sc more than 4 times from the initial ash has been shown.
Self-categorization: a resource for the management of experiential entitlement in talk about child death
Authors: Rafaely Daniella 
Published: January 2023

Abstract
In this paper, I examine self-categorization practices as resources for the interactional organization of relative experiential entitlements. Locating the study in talk about child death, an explicitly moral domain of social life, this study utilizes 18 radio-based interactions from a South African talk-radio broadcaster. Using an ethnomethodological, conversation-analytic approach, I examine affective responses to reports of child deaths, demonstrating how these practices reproduce child death as a contemporary social and moral concern. My findings demonstrate how practices of, and variations in, self-reference and self-categorization are resources for managing relative rights and obligations, thereby reproducing common-sense knowledge about parents and children in contemporary South African society. This research contributes to advancing knowledge in the fields of membership categorization analysis and the social organization of experience.

Published: January 2023

ABSTRACT
The countermovement jump (CMJ) is one of the most used performance assessments in strength and conditioning. Although numerous studies discuss the usability of different metrics in this test, this is often performed within the context of a specific aim. However, to our knowledge, no information currently exists providing practitioners with some over-arching recommendations on which metrics to choose when the purpose of using the test differs. This article discusses how the metrics selected to monitor during CMJ testing may differ when aiming to use it as a proxy for athletic performance, as part of neuromuscular fatigue monitoring, or as part of a test battery for return to performance in injured athletes.

Impulse control and/or gambling disorders can be triggered by dopamine agonist therapies used to treat Parkinson's disease, but the cognitive and neurobiological mechanisms underlying these adverse effects are unknown. Recent data show that adding win-paired sound and light cues to the rat gambling task (rGT) potentiates risky decision-making and impulsivity via the dopamine system, and that changing dopaminergic tone has a greater influence on behavior while subjects are learning task contingencies. Dopamine agonist therapy may therefore be potentiating risk-taking by amplifying the behavioral impact of gambling-related cues on novel behavior. Here, we show that ropinirole treatment in male rats transiently increased motor impulsivity but robustly and progressively increased choice of the high-risk/high-reward options when administered during acquisition of the cued but not uncued rGT. Early in training, ropinirole increased win-stay behavior after large unlikely wins on the cued rGT, indicative of enhanced model-free learning, which mediated the drug's effect on later risk preference.Ex vivocFos imaging showed that both chronic ropinirole and the addition of win-paired cues suppressed the activity of dopaminergic midbrain neurons. The ratio of midbrain:prefrontal cFos+neurons was lower in animals with suboptimal choice patterns and tended to predict risk preference across all rats. Network analyses further suggested that ropinirole induced decoupling of the dopaminergic cells of the VTA and nucleus accumbens but only when win-paired cues were present. Frontostriatal activity uninformed by the endogenous dopaminergic teaching signal therefore appeared to perpetuate risky choice, and ropinirole exaggerated this disconnect in synergy with reward-paired cues.SIGNIFICANCE STATEMENTD2/3receptor agonists, used to treat Parkinson's disease, can cause gambling disorder through an unknown mechanism. Ropinirole increased risky decision-making in rats, but only when wins were paired with casino-inspired sounds and lights. This was mediated by increased win-stay behavior after large unlikely wins early in learning, indicating enhanced model-free learning. cFos imaging showed that ropinirole suppressed activity of midbrain dopamine neurons, an effect that was mimicked by the addition of win-paired cues. The degree of risky choice rats exhibited was uniquely predicted by the ratio of midbrain dopamine:PFC activity. Depriving the PFC of the endogenous dopaminergic teaching signal may therefore drive risky decision-making on-task, and ropinirole acts synergistically with win-paired cues to amplify this.

Recommender system provides the significant suggestion towards the effective service offers for the vast range of big data. The Internet of Things (IoT) environment exhibits the value added application services to the customer with the provision of the effective collection and processing of information. In the extension of the IoT, Internet of Medical Things (IoMT) is evolved for the patient healthcare monitoring and processing. The data collected from the IoMT are stored and processed with the cognitive system for the data transmission between the users. However, in the conventional system subjected to challenges of processing big data while transmission with the cognitive radio network. In this paper, developed a effective cognitive 5G communication model with the recommender model for the IoMT big data processing. The proposed model is termed as Ranking Strategy Internet of Medical Things (RSIoMT). The proposed RSIoMT model uses the distance vector estimation between the feature variables with the ranking. The proposed RSIoMT model perform the recommender model with the ranking those are matches with the communication devices for improved wireless communication quality. The proposed system recommender model uses the estimation of direct communication link between the IoMT variables in the cognitive radio system. The proposed RSIoMT model evaluates the collected IoMT model data with the consideration of the four different healthcare datasets for the data transmission through cognitive radio network. Through the developed model the performance of the system is evaluated based on the deep learning model with the consideration of the collaborative features. The simulation analysis is comparatively examined based on the consideration of the wireless performance. Simulation analysis expressed that the proposed RSIoMT model exhibits the superior performance than the conventional classifier. The comparative analysis expressed that the proposed mode exhibits ~3 – 4% performance improvement over the conventional classifiers. The accuracy of the developed model achieves 99% which is ~3 – 9% higher than the conventional classifier. In terms of the channel performance, the proposed RSIoMT model exhibits the reduced recommender relay selection count of 1 while the other technique achieves the relay value of 13 which implies that proposed model performance is ~4-6% higher than the other techniques.

Published: January 2023

This study aims to identify the factors that influence switching behavior of customers in selecting Sharia banking services in Indonesia. This study employed a positivistic research paradigm to explain and predict the determinants of switching behavior of banking customers. In this study, a quantitative approach was adopted to examine the relationship between variables, determine variable causality, generalization, and prediction. The results of data analysis indicate that the important factors that determine switching behavior are religiosity, internet banking, and employee hospitality. Additionally, conditions that can hinder switching behavior are the fact that customers are increasingly rational. Lastly, the strategy that need to be developed by Islamic banking related to switching behavior is to maintain customer loyalty. The managerial implication of this research is that efforts are needed to increase understanding of Islamic banking to a higher level of education through a rational approach. Future research is expected to include price variables, number of offices, and other rational-based services to explore in more detail the determinants of switching behavior.

Published: January 2023

National Rural Health Mission (NRHM) has created a cadre of trained female community health activists called Accredited Social Health Activist (ASHA) to strengthen the health care system and to mobilize community towards increased utilization of existing health services. The contribution of the Accredited Social Health ActivistASHA) to the achievement of the country’s targets for new-born & child health services is critical. The present study was planned with objective to assess & compare the level of knowledge of ASHA workers regarding child health services working in rural and urban areas of a block of Haryana. The present cross-sectional, community-based study was conducted in block Barwala, district Hisar of Haryana. The assessment of knowledge of ASHA workers was done on the basis of scoring. Appropriate statistical tests like percentages and chi-square (χ2) test were applied. Regarding child health services majority of ASHA workers had good knowledge, assessed by score gained by them and none of them was having poor knowledge about child health services. However, in rural area score gained was better than urban area & the observed difference was found to be statistically significant. Majority of ASHA workers either working in rural or urban areas, were having inadequate knowledge about identification of danger signs during diarrhoea & acute respiratory infection in a child and danger signs of new born. They had adequate knowledge regarding cord stump care; breast Feeding practices; routine Immunization; Vitamin A supplement and home based post natal care (HBPNC) visits. Inadequate knowledge of ASHA workers regarding new born care should be taken into consideration. Supportive supervision should be done in their working area.

Published: January 2023

Background:
The aim of this single-center randomized controlled trial was to compare primary wound closure using a suture with secondary wound healing of pin sites after removal of temporary external fixation.

Methods:
This noninferiority trial included all patients who were treated with a temporary external fixator on an upper or lower extremity at 1 institution. The primary outcome was pin-site infection. Secondary outcomes were measured at 2, 6, 12, 24, and 52 weeks and included all other complications, time to pin-site wound healing (in weeks), the most satisfactory pin site as rated by the patient, the visual analog scale (VAS) score for pain, and the Vancouver Scar Scale (VSS). The most proximal pin site was randomly allocated (1:1) to either primary closure or secondary wound healing, and the other pin sites were treated alternately.

Results:
Seventy patients, providing 241 pin sites, were included between January 1, 2019, and March 1, 2020. A total of 123 pin sites were treated with primary closure and 118, with secondary wound healing. The median age was 55 years (interquartile range, 46 to 67 years), 44% were male, and the median duration of the external fixation was 6 days (interquartile range, 4 to 8 days). There were no pin-site infections in either group. Wound healing was significantly faster in the primary closure group (median of 2 versus 6 weeks, p = 0.013). The VSS and patient satisfaction showed no differences between groups. There was 1 case of fracture-related infection not related to any pin site.

Conclusions:
Primary closure of temporary external fixator pin sites did not result in higher infection rates compared with secondary wound healing, and pin sites healed significantly faster after primary closure. Primary closure should therefore be considered in patients treated with a temporary external fixator.

Published: January 2023

Abstract
To identify molecular targets that would be missed by more conventional methods of analysis, we applied a novel unsupervised method to cluster gene interactomes represented as networks in pediatric sarcoma. RNA-Seq data were mapped to protein-level interactomes to construct weighted networks that were then subjected to a non-Euclidean, multi-scale geometric approach centered on a discrete notion of curvature. This provides a measure of the functional association between genes in the context of their connectivity. In confirmation of the validity of this method, hierarchical clustering revealed the characteristic EWSR1-FLI1 fusion in Ewing sarcoma. Furthermore, assessing the effects of in silico edge perturbations and simulated gene knockouts as quantified by changes in curvature, we found non-trivial gene associations not previously identified.

Published: January 2023

Abstract

A typical earthen embankment is a raised compacted wall-like structure basically consisting of an outer shell to permit seepage of minimum piping, a centrally located core, and a base drainage filter to check the flow of water through it. The earthen embankment needs a centrally stabilized clay core made off locally available puddle clay composite with coarse soil in order to store and divert storm water. In the current work, a compression moulding technique was used employed to build a low-cost composite for clay core using readily available bentonite reinforced with fly-ash. The experimental work initiated with the characterization of the locally collected soil, bentonite and fly-ash along with the micro structural investigation utilizing Scan Electron Microscopy (SEM) and Energy Dispersive X-Ray (EDX). Proctor test has been employed to stabilize clay core composite using different percentage ratios of bentonite and fly-ash according to the Taguchi L9 orthogonal array. The obtained maximum dry density (MDD) and optimum moisture content (OMC) were arranged in the design of the experiment (DOE) to examine the best possible results. The experimental findings from the Taguchi optimization approach determine the optimum values of OMC and MDD. The Analysis of variance (ANOVA) was performed to determine the primary factor influencing the strength of the clay core using signal-to-noise (S/N) ratio. A meta-heuristic method named as Sunflower optimization technique was employed to validate the generated optimum OMC and MDD. Verified OMC and MDD results were corroborated with the impervious core properties of the existing structures.

Published: January 2023

Abstract

Changes in Meaning in life (MIL) have been shown to be particularly important when people face very stressful events such as receiving a cancer diagnosis and treatment. Active coping strategies have been related to higher levels of MIL in people with a diagnosis of cancer.
Objective: To explore the evolution of MIL in a sample of cancer patients at the time of their diagnosis and three, six, and nine months after surgery, and identify the association between coping strategies three months after diagnosis (T2) and levels of MIL at the different moments in the cancer process (T1-T4).
Methods: We assessed MIL at diagnosis and three, six, and nine months after surgery, and coping strategies (fighting spirit, anxious preoccupation, hopelessness, fatalism, and cognitive avoidance) three months after surgery, in 115 women with a diagnosis of Stage I-III breast cancer.
Results: We found higher levels of MIL nine months after surgery, compared to previous stages. MIL correlated significantly and positively with a fighting spirit and cognitive avoidance, and negatively with hopelessness and anxious preoccupation.
Conclusions: Results highlight the importance of coping in relation to meaning-making processes in cancer. Meaning-centred interventions could help patients who are in the process of coping with the cancer experience.
