Abstract
Gymnosia orchidis (G. orchidis) is a valuable Tibetan medicinal resource with significant medicinal, ecological, and economic value. However, the growth of G. orchidis is severely constrained by stringent natural conditions, leading to a drastic decline in its resources. Therefore, it is crucial to study the suitable habitat areas of G. orchidis to facilitate future artificial cultivation and maintain ecological balance. In this study, we investigated the suitable zones of G. orchidis based on 79 occurrence points in the Qinghai-Tibet Plateau (QTP) and 23 major environmental variables, including climate, topography, and soil type. We employed the Maximum Entropy model (MaxEnt) to simulate and predict the spatial distribution and configuration changes of G. orchidis during different time periods, including the last inter-glacial (LIG), the last glacial Maximum (LGM), the Mid-Holocene (MH), the present, and future scenarios (2041—2060 and 2061—2080) under three different climate scenarios (SSP126, SSP370, and SSP585). Our results indicated that annual precipitation (Bio12, 613—2466 mm) and mean temperature of the coldest quarter (Bio11, -5.8—8.5 °C) were the primary factors influencing the suitable habitat of G. orchidis, with a cumulative contribution of 78.5%. The precipitation and temperature during the driest season had the most significant overall impact. Under current climate conditions, the suitable areas of G. orchidis covered approximately 63.72×104/km², encompassing Yunnan, Gansu, Sichuan, and parts of Xizang provinces, with the highest suitability observed in the Hengduan, Yunlin, and Himalayan mountain regions. In the past, the suitable area of G. orchidis experienced significant changes during the Mid-Holocene, including variations in total area and centroid migration direction. In future scenarios, the suitable habitat of G. orchidis is projected to expand significantly under SSP370 (30.33%—46.19%), followed by SSP585 (1.41%—22.3%), while contraction is expected under SSP126. Moreover, the centroids of suitable areas exhibited multidirectional movement, with the most extensive displacement observed under SSP585 (100.38 km²). This research provides valuable insights for guiding the selection of introduced species, artificial cultivation, and resource conservation in the future, while also offering theoretical support for the protection of endangered species.

Abstract
Background The shortage and turnover of general practitioners (GPs) have become significant global public health issues. The increased workload and psychological pressure experienced by GPs during the COVID-19 period may exacerbate their turnover intention. This study aimed to investigate the current status of turnover intention among GPs during the COVID-19 pandemic and its relationship with job satisfaction, workplace violence, and perceived overqualification. Methods A cross-sectional survey was conducted among GPs in Chongqing from March to April 2022. A total of 1885 GPs completed a questionnaire that covered demographic characteristics, turnover intention, job satisfaction, workplace violence, and perceived overqualification. Descriptive statistics, Pearson correlation analysis, and hierarchical linear regression analysis were performed using SPSS 25.0. Results Overall, 80.9% of the GPs had a medium or high level of turnover intention. Hierarchical linear regression analysis revealed several significant predictors of turnover intention, including negative predictors such as job satisfaction (β = -0.537), female sex (β = -0.043), age (β = -0.257), and within-staff status (permanent employment status) (β = -0.108). Positive predictors included workplace violence (β = 0.085), possession of a bachelor's degree (β = 0.073), middle (β = 0.068), senior professional title (β = 0.104), part-time management role (β = 0.061), and long working hours per week (β = 0.066). Perceived overqualification did not significantly predict turnover intention. Conclusion During the period of COVID-19 normalization, GPs in Chongqing demonstrated a significant tendency toward turnover. Mighting pressure, enhancing job satisfaction, and fostering a secure working environment can effectively reduce GPs' intention to leave. Health administrators should formulate corresponding policies to improve GP retention.

Published: January 2024

Abstract
Our long-term goal is the development of a wearable warning system that uses electrocutaneous stimulation. Here, we investigated how stimulation pulse amplitude, pulse intervals, and location were perceived in order to select which of these three parameters are practical for designing a warning signal. The upper right arm was stimulated in 81 healthy volunteers with biphasic rectangular current pulses with a pulse width of 150 µs. Eight electrode pairs were placed around the upper right arm. Nine varying amplitudes 1 to 9, equally spaced between the individual perception and intolerance thresholds were presented to the participant in a pseudo-random order (equal for each participant). After a training phase, the participant was asked to rate the presented stimulation amplitude between 1 and 9. Further, five consecutive stimulation pulses with varying intervals (pauses) from 200 ms down to 0.5 ms were presented to the participant. The participant was asked to rate the perceived stimulation regarding the perception as ’Individual pulses’, ’Pulsating’, ’Vibrating’, or ’Continuous’. Next, five consecutive stimulation pulses were presented in a pseudo-random order at the 8 electrode pair positions. After a training phase, the participant was asked to report the stimulated electrode pair. The median reported amplitudes [25%-75%-percentile] for presented amplitudes 1 to 9 are: 1[1-1], 2[2-3], 3[2-4], 3[3-4], 4[3-5], 5[4-6], 6[4-7], 7 [5-8] and 7.5 [6-8]. It shows an underestimation of the perceived amplitude for the presented amplitudes ≥ 4. We conclude that a fine grained variation of the stimulation amplitude is not primarily practical for the design of a warning signal. Participants perceived electrocutaneous pulses as ’Individual pulses’ for median intervals above 74 ms, as ’Pulsating’ between 44 ms and 74 ms, as ’Vibrating’ between 12 ms and 44 ms, and as ’Continuous’ below 12 ms. The majority of the electrode pairs were reported correctly or at the two neighboring electrode pairs. The determined intervals in combination with the small location error offer the basis for the design of a spatio-temporal warning pattern. Our investigations provide the basis for appropriate warning signals for electric warning wearables.

Abstract
Background Epigenetic modifier gene mutations (EMM) have been reported to be associated with poor prognosis in acute myeloid leukemia (AML). Whether allogeneic stem cell transplantation (allo-HSCT) can improve outcomes in this patients remains unknown.Material/Methods: This study retrospectively collected clinical information of 353 AML patients with gene mutations detected by next-generation sequencing (NGS) and analyzed the therapeutic effect of allogeneic stem cell transplantation in acute myeloid leukemia patients with epigenetic modifier gene mutations.Results EMM-positive patients tended to have inferior OS compared with EMM-negative patients (p = 0.065, HR = 1.343, 95%CI: 0.981–1.838), EMM-positive patients had inferior LFS (p = 0.031, HR = 1.385, 95%CI: 1.030–1.863). In EMM-positive patients, multivariate analysis showed that patients who received allo-HSCT had a superior OS (yes vs. no, p < 0.001, HR = 0.213, 95%CI: 0.134–0.339, Table 3) and LFS (yes vs. no, p < 0.001, HR = 0.303, 95%CI: 0.199–0.461, Table 3) compared with patients who did not receive allo-HSCT. A total of 220 patients received allo-HSCT in all patients. Univariate analysis in patients undergoing allo-HSCT showed that EMM was not a risk factor for OS (EMM-positive vs. EMM-negative, p = 0.470, HR = 1.192, 95%CI: 0.740–1.920) and LFS (EMM-positive vs. EMM-negative, p = 0.323, HR = 1.235, 95%CI: 0.813–1.876).Conclusion EMM tended to be a poor risk factor for OS and was a poor risk factor for LFS in our cohort. Allo-HSCT might improve the OS and LFS of EMM-positive patients.

Abstract
To improve the forecast skills of Subseasonal to Seasonal (S2S) models in predicting Iran's southwest precipitation from 1 to 4 weeks ahead, the characteristics of observed precipitation and atmospheric variables were compared with the corresponding hindcasts generated by the CMA, UKMO, ECWMF, and Meteo France models. This comparison was performed by utilizing several deterministic and probabilistic metrics. Precipitation data at 176 rain gauge stations and the NOAA-based data of atmospheric flows for Dec-April 1995–2014 constructed our observed datasets. While almost all models underestimated wet events over the southern and eastern districts, these events were overestimated in the western and northern regions. Moreover, all models overforecasted the frequency of wet events in all leads. Except for Meteo-France, the over-forecasting was usually more pronounced in eastern drylands than in western wet areas. The correlation scores were high during the first week and decreased with the increase in lead times. The ECMWF yielded the highest correlation scores in all regions and provided the more significant deterministic and probabilistic forecast skills in all leads over western districts. As a most conservative representative of other models, the UKMO efficiently captured signals of the El-Niño Southern Oscillation (ENSO) and Madden Julian Oscillation (MJO) over the study area and the Middle East. Also, this model competently predicted the characteristics of the near-surface (mid-atmosphere) moisture transport (air vertical velocity) over these areas, particularly during the MJO's rainy phases. Our findings, presented for the first time, enhance the quality of operational S2S precipitation forecasts in Iran and the Middle East.
Industrial land dependence and industrial land-use efficiency: Land resources curse hypothesis and test
Authors: Yang Xinmei , Zhou Ruihui 
Published: January 2024

Abstract
Historically, local governments have relied on their monopoly position in the land market to consistently provide abundant industrial land at low prices, resulting in the adverse “resource curse” effect, whereby dependence on industrial land undermines high-quality industrial development. Avoiding the negative impact of industrial land dependence on land resources is an inherent requirement and the sole path towards establishing China's modern economic system based on high-quality industrial development. This study examines the impact, transmission mechanism, and heterogeneous effects of industrial land dependence on industrial land use efficiency using panel data from 286 cities at the prefecture level and above in China from 2003 to 2019. The findings indicate that: (1) industrial land dependence diminishes the efficiency of industrial land utilization. (2) Concerning the transmission mechanism, industrial land dependence exacerbates the misallocation of resources, hampers innovation, and leads to increased pollution emissions, thereby reducing industrial land utilization efficiency and compromising industrial development quality. (3) The study also examines the heterogeneity effect across varied regions, resource-rich cities, city sizes, and land supply reduction policies, demonstrating the pervasive nature of industrial land dependence at the national level. This study offers empirical evidence and policy implications from the perspective of the industrial land resource curse, aiming to facilitate the systematic withdrawal of current industrial land and foster high-quality industrial development.

Authors: Tang Lisheng , Jin Yuanyuan , He Xiaoyan , Huang Ran 
Published: January 2024

Abstract
The stability to against hydrolysis while maintaining excellent elasticity is a constant challenge in the development of biodegradable and environmental-friendly polyester elastomer. While monomers of longer chain can provide higher stability, the high crystallinity and rigidity impair their application in fabricating elastomer. This work reported a star-crosslinked Poly(butanediol-hexanediol-isosorbitol-itaconate-sebacate) (PBHIIS) elastomer synthesized by esterification and thermal curing. With the decrystallization effect of isosorbide as a large and rigid monomer, the original rigid Poly(butanediol-hexanediol-itaconate-sebacate) successfully transformed to be elastomer with lower Tm and Tg, much higher Elongation at break, and smaller tensile modulus, and biodegradability is also improved. The strategy is demonstrated to be efficient and may serve as a potential technique in the future development of biodegradable elastomers.

Published: January 2024

Abstract

Continuous alumina fibers with excellent thermal stability are essential in high-temperature applications. In this study, 0~1 wt% RE2O3 (RE = Y, Er, Yb, and Ho) were added to the alumina fibers to enhance thermal stability. The impact of RE2O3 addition on alumina fibers’ transformation and microstructure evolution of during the sintering process was systematically studied. The influence of single- and two-step sintering processes on the fiber microstructures was elucidated. The results suggested that adding RE2O3 impeded fiber densification, inhibited alumina grain growth, and enhanced the thermal stability of fibers. Using a two-step sintering process facilitated the achievement of fully dense alumina fibers with fine grains. The alumina fibers added with 1.0 wt% RE2O3 exhibited a remarkable strength retention rate of up to 93% after exposure to 1200 °C for 10 h. The TEM analysis revealed that RE elements segregation at α-Al2O3 grain boundaries due to their larger radius than the Al element contributed to stabilizing the microstructures of α-Al2O3 fibers at high service temperature.

Authors: Yang Baoqiang 
Published: January 2024

Abstract

If an athlete's body movements are not standardized or make mistakes during the training process, it will greatly affect their training effectiveness. Therefore, professional guidance is necessary when conducting action training. The development of optical technology has promoted the widespread application of human bone key point detection technology in multiple fields, such as human-computer interaction and motion analysis. Based on this, this article takes the image segmentation algorithm of optical topology sensors as the prototype and conducts research and development on the training video simulation system for athletes. After studying the operating principle of optical topological sensors, this article applies topological photonic crystals to the development of sensors and conducts a series of sensing performance analysis. The results show that the edge states in topological photonic crystals play an indispensable role in sensors. Then, this article studied the image segmentation algorithm, which is a key technology in the field of image analysis and detection. The quality of the corresponding segmentation results has a very direct impact on the information feature extraction and recognition of subsequent images. Therefore, this article made relevant improvements to it after the research. Finally, this article successfully developed an athlete training video simulation system, which achieved automatic analysis of training videos. Through various tests, it was proven that the system has good performance and runs stably.
In-Vehicle Full-window Augmented Reality System (FARS) for Passengers: Effects on Spatial Knowledge and User Experience
Authors: Kim Hyunjeong , Lee In-Kwon 
Published: January 2024

Abstract

In recent years, automobiles have introduced various infotainment systems for drivers and passengers, providing a high-tech interactive space. While the focus has been on head-up display (HUD)-oriented services for the driver, advances in autonomous driving technology are increasingly driving research into improving the experience for non-driver passengers. However, HUD systems for passengers are limited, and few studies have empirically evaluated their effectiveness or preferences. In this paper, we propose a novel infotainment system for passengers in moving vehicles, the Full-window Augmented Reality System (FARS), and empirically verify its impact on passengers’ spatial perception and riding experience. The FARS is implemented in a real vehicle using a short-throw projector and a transparent AR film to create an AR display on the entire right window of the passenger seat. To explore the impact of FARS on users’ spatial knowledge and preferences, we further conducted a user study comparing the difference between FARS and the Seat Back Display (SBD), commonly used in passenger mobility services. The results suggest that the FARS is a valuable infotainment system for passengers and has advantages in memorizing the features or locations of specific environments outside the vehicle while enhancing the user’s travel experience.

Published: January 2024

Abstract
The objective of this paper is to demonstrate how extractive FDI flows affect institutional quality in sub-Saharan Africa. We used a panel VAR model to estimate data from the World Bank's WDI and WGI databases between 1996 and 2021. Our analysis of the robustness of our results using impulse response functions based on Monte Carlo simulations revealed that FDI flows from the extractive industries have a negative and significant impact on the quality of institutions in sub-Saharan Africa. Therefore, it is crucial for the authorities in these countries to establish robust and trustworthy institutions that can effectively oversee FDI inflows into sub-Saharan African economies.
Educational workshops for health care professionals on compassionate communication following adverse events in healthcare: a mixed methods evaluation
Authors: McQueen Jean , Gordon June , Berry Gillian , Cook Marcia 
Published: January 2024

Abstract
Background When things go wrong in healthcare patients and families want to be included, they want open honest compassionate communication; however, in practice,this does not always happen. This study evaluated the impact of compassionate communication skills training offered to 74 health care staff members across NHS Scotland. Training focused on ‘good’ patient family involvement during adverse event reviews using a person-centred approach.
Methods: The evaluation, informed by the Kirkpatrick model, was completed by two independent reviewers. Both qualitative and quantitative data were gathered from 74 health care participants who completed the training. The analysis of feedback from course evaluation forms, and pre- and post measures of knowledge and confidence, together with thematic analysis from reflective practice assignments, are outlined and discussed.
Results The quantitative outcomes from the pre- and post-training polls indicated that participants were more confident including and communicating with patients and families. They felt better able to craft and deliver an apology to patients and families. They valued the delivery methods used which combined theory and practice. Qualitative analysis of participants' reflective practice logs suggested that the training-inspired improvement and empathic presence, as participants valued the models, tools presented and the interactive nature of the training delivery. This contributed to a drive among participants to embed more compassionate communication into their review process.
Conclusion After completing the compassionate communication skills, trained staff members felt more confident, and some participants reported skill enhancement and changes in practice through a more person-centric compassionate approach to patients and families involved in the adverse event review process.
