Authors: ChenyuWang  , XiaoweiZhou  
Published: April 2024

Abstract

Objective: This research undertakes a comprehensive ex-amination of the direct and indirect effects of the health human capital, inclusive of the dimension of psychological health, on the quality of exports at the firm level. The study underscores the potential of a well-structured human capital to alleviate psychological health issues, thereby augmenting productivity and enhancing the quality of exports.
Methods: The empirical analysis is conducted using firm-year data extracted from three harmonised data-bases. The study employs a benchmark regression to validate the positive correlation between the healthy human capital structure, with a particular emphasis on psycho-logical health, and the quality of exports. The role of innovation capacity as a facilitator is further elucidated through a mediation analysis. To verify the validity of the regression results, we undertake robustness checks on the regression methods and regional disparities.
Results: The results indicate that a healthy human capital structure, which reflects psychological health of human capital, significantly enhances innovation capacity of staff. Also, there is a positive relationship between in-novation capacity and export quality. Then, the mediating effect of innovation capacity accounts for 17% of the total impact of the healthy human capital structure on the quality of exports. The study also uncovers regional disparities in the influence of local human resources on a firm's healthy human capital structure, with a more pronounced mediation impact observed in enterprises located in the eastern region compared to those in the central and western regions.
Conclusions: The findings of the study states that healthy human capital structure reflects psychological health of human capital, it affirms crucial role of healthy human capital structure in export products' quality and the significant role of innovation capacity in enhancing the quality of exports through the healthy human capital structure. The study also emphasises the necessity of considering regional disparities in the influence of local human resources on a firm's health human capital structure. These insights hold substantial value for firms aiming to augment their export quality through the im-provement of their human capital structure and innovation capacity. Our findings indicate the significance of a company's internal human resources, specifically its healthy human capital structure with dimension of psychological health and innovation potential, in enhancing export quality.

Abstract

Background: Cryotherapy is a low-cost treatment option recommended by clinical practice guidelines in acute ankle sprain. However, current quality of the evidence that supports cryotherapy is still unclear. New high-quality randomised controlled trials are needed. The aim of the FROST randomized controlled trial is to investigate the effectiveness of cryotherapy on function, pain intensity, swelling and dorsiflexion range of motion in people with an acute episode of ankle sprain.
Methods:This is a protocol of the FROST two-arm randomised controlled trial. Eighty-two participants over 18 years old presenting grade I or II ankle sprain up to 72 hours from the episode will be randomly allocated to Ice Group (i.e., home prescription to apply cryotherapy on the injured ankle with elevation plus non-steroidal anti-inflammatory medication – NSAID) or No Ice Group (i.e., elevation plus NSAID). Our primary outcome is function measured by the Lower Extremity Functional Scale (LEFS) questionnaire. Our secondary outcomes are pain intensity (11-points numerical rating scale), swelling (figure-of-eight method) and dorsiflexion range of motion (goniometry). Participants will be assessed at baseline, post-treatment (7 to 14 days) and 12 weeks after allocation. Analysis will follow the intention-to-treat principle using mixed linear models.
Discussion: The results of this study will clarify the effectiveness of cryotherapy in acute ankle sprain for better clinical decision-making processes.

Published: April 2024

Abstract

In recent years, innovation and entrepreneurship have become the source of power to promote economic growth. Innovation and entrepreneurship can not only bring economic prosperity and development, but also alleviate the employment dilemma. The country is in urgent need of high-level innovation and high-level entrepreneurship, so entrepreneurship research has become a hot topic in academia. However, not all entrepreneurial enterprises can succeed, and the vast majority of entrepreneurial activities end in failure. Therefore, academia has begun to pay attention to the factors that affect the success of entrepreneurial enterprises. In this study, on the basis of combing relevant research literature at home and abroad, the concepts of psychological compatibility, team interaction quality, team cohesion and entrepreneurial performance are defined, and the theoretical model of the influence mechanism between entrepreneurial team psychological compatibility, team interaction quality, team cohesion and entrepreneurial performance is constructed, and the relevant hypotheses are put forward for testing. The research finds that: (1) the psychological compatibility of entrepreneurial team has a significant positive impact on entrepreneurial performance; (2) team cohesion and team interaction quality play an intermediary role in the influence of team psychological compatibility on entrepreneurial performance; (3) team interaction quality and team cohesion play a chain mediation effect in the influence of team psychological compatibility on innovation performance. Finally, three practical enlightenments are proposed, which have certain reference value for entrepreneurial teams to better seek entrepreneurial team members and better carry out entrepreneurial activities in the initial entrepreneurship and team evolution.

Abstract

The surface chemistry of the Fischer-Tropsch catalytic reaction over Co has still several unknows. Here, we report an operando X-ray photoelectron spectroscopy study of Co(0001) and Co(1014), and operando high energy surface X-ray diffraction of Co(0001), during the Fischer-Tropsch reaction at 0.15 bar − 1 bar and 406 K − 548 K in a H2/CO gas mixture. We find that the Co surfaces remain metallic under all conditions and that the coverage of chemisorbed species ranges from 0.4–1.7 monolayers depending on pressure and temperature. The adsorbates include CO on-top, C/-CxHy and various longer hydrocarbon molecules, indicating a rate-limiting direct CO dissociation pathway and that only hydrocarbon species participate in the chain growth. The accumulation of hydrocarbon species points to the termination step being rate-limiting as well. Furthermore, we demonstrate that the intermediate surface species are highly dynamic, appearing and disappearing with time delays after rapid changes in the reactants’ composition.

Abstract
Shuttle effect of lithium polysulfides in lithium sulfur batteries greatly influenced their commercialization. Therefore, it is urgent to develop a cheep and effective way to alleviate the shuttle effect. Fe is an active transition element which has good catalytic ability, in this work, a simple wet impregnation method was used to make Fe ions infiltrate into the pores of BP2000 (a kind of commercial conductive carbon), then it was calcined in N2 atmosphere to get a Fe2O3/BP2000 composite and used as a separator modification layer. The Fe2O3 nano particles are decorated in the pores of BP2000 which greatly enhanced the absorption ability on lithium polysulfides, additionally it also has excellent catalytic effect on lithium polysulfides, thus the Fe2O3/BP2000 layer can be served as a secondary collector to re-engage the polysulfides in the cathode reaction. In this way, the lithium sulfur batteries use the Fe2O3/BP2000 modified separator show impressive electrochemical performances.

Abstract

Intelligent livestock farming has been a major focus of attention in recent years. Using deep learning to assist livestock management can effectively reduce labor loss and improve management efficiency. Lightweighting plays a key role in the deployment and practical use of deep learning models, and most existing sheep-based deep learning models do not focus on this, which has become a major factor limiting the development of smart sheep farming. Therefore, in this paper, first, a GAM-YOLOv7-tiny neural network model for object detection of sheep was investigated. The size of the model reached 3.5G, which was a reduction to 26.3% of the original size, the FLOPS was reduced by 74.1%, the experimental result reached 96.4% of mAP and the FPS reached 88.232 on an RTX 1650Ti. Second, a Soft-NMS-AlexNet neural network model for key point recognition of sheep bodies was investigated with a model size of 1.97G, and the final experimental results achieved 82% AP and 190.86 ± 23.97 FPS. Finally, we completed the behavior recognition of the standing and lying posture of sheep using the pose estimation model, which provides a research solution for performing behavioral monitoring and giving early warnings for diseases for sheep.
Investigation of Dynamics of a Droplet Impacting a Pair of Circular Cylinders

Published: April 2024

Abstract

This study explores the intricate dynamics of droplet impact on adjacent cylindrical surfaces. Utilizing the multiphase lattice Boltzmann method and the Allen-Cahn equation, the research delves into how various factors such as droplet size, velocity, surface wettability, and cylinder proximity influence the impact dynamics. It is found that increasing the distance between the cylinders enhances the penetration of the liquid phase and the maximum extent of the liquid ligament. Specifically, at certain distances, the droplet tends to reach equilibrium predominantly on one side of the cylinders, resulting in a shorter ligament length. The study also examines the impact of Reynolds and Weber numbers on droplet dynamics. A reduction in the Reynolds number diminishes the impact inertia, leading to a decrease in the initial length of the liquid ligament and the wetted surface area. Over time, however, the final length of the liquid between the cylinders and the wetted surface is higher for lower Reynolds number impacts due to less liquid separation from the cylinder surfaces. An increase in the Weber number, conversely, reduces surface tension effects relative to inertial force, causing more extensive spreading of the droplet on the cylinder surfaces and altering the movement of separated droplets post-impact. Furthermore, the study highlights the influence of surface wettability. As the contact angle increases, hydrophobic effects repel the liquid phase, resulting in more elongated droplets post-impact. At lower contact angles, the predominance of surface adhesion facilitates quicker equilibrium attainment, while higher contact angles lead to prolonged equilibrium due to oscillatory droplet behavior. These findings offer novel insights into the interactions between droplets and adjacent curved surfaces, with significant implications for optimizing industrial processes and developing new technologies in fields such as inkjet printing and spray coating.

Abstract

Background
Study of the Pseudomonas aeruginosa resistance has become an urgent topic since antibiotic resistance has escalated exceedingly. Even with the intense interest, development of new antibiotics and other therapeutic strategies for P. aeruginosa infections is at a painstakingly slow pace due to the complexity of drug resistance, as well as the lack of a deep understanding of the pathogenic mechanisms for P. aeruginosa. Repurposing of the already FDA-approved drugs is one of the promising strategies in combating Pseudomonas resistance or virulence.
Results
In this study we tested the anti-virulence effect of sub-minimum inhibitory concentration (MIC) of atorvastatin and rosuvastatin against P. aeruginosa. The assessed virulence factors include: biofilm formation and production of pyocyanin, protease, hemolysin and rhamnolipids. Significantly, atorvastatin and rosuvastatin decreased the production of bacterial biofilm and reduced other virulence factors. Moreover, the anti-quorum sensing (QS) activity of atorvastatin and rosuvastatin was assessed using qRT-PCR. the expression of QS genes was reduced using atorvastatin and rosuvastatin. Furthermore, in-vivo capability of statins to protect mice against P. aeruginosa was assessed, both drugs protected mice from P. aeruginosa and enhanced their survival. In addition, molecular docking was used to evaluate binding between statin and QS-receptors, rosuvastatin showed better interaction with QS-receptors than atorvastatin, as rosuvastatin has higher binding scores with LasR, RhlR, and LasB, while atorvastatin showed higher binding with the PqsR.
Conclusion
statins attenuated the pathogenicity of P. aeruginosa, locating it as a plausible potential therapeutic agent for the treatment of its infections.

Abstract
Infections of Human papillomaviruses (HPVs) frequently spread through sexual contact. The aim of this study was to assess the persistence and clearance rate of HPV infection. A prospective cohort study was conducted between January and December 2023 among patients attending gynecology unit of FHCSH in Bahir Dar, northwest Ethiopia. Out of 297 study participants, 95 women were followed, of these 89/95(93.7%) were HPV positive at the baseline study. Of which, 41/89(46.1%) did not receive treatment, the rest 48/89(53.9%) were treated. Among the women without treatment, HPV persistence and clearance rates were 65.9% (27/41) and 34.1% (14/41) respectively while persistence rate of 46.3% (19/41) and clearance rate of 53.7% (22/41) were observed in 12-month follow up period. Among women with treatment, HPV persistence rate of 45.8% (22/48) and clearance rate of 54.2% (26/48) were recorded in six while persistence rate of 33.3% (16/48) and clearance rate of 66.7% (32/48) were observed in 12- month follow up period. The findings of our study indicated that the high persistence rate and low clearance rate of HPV infection. Detection of persistent HPV infection without treatment or after treatment should be considered as the main risk factor for the development or recurrence of cervical neoplasia.

Published: April 2024

Abstract

Parvoviruses have evolved to possess a linear single-stranded DNA (ssDNA) genome ranging from 4 to 6.3 kb. Adeno-associated virus (AAV), a member of the Parvoviridae family, contains approximately 5 kb of linear ssDNA within its capsid. This ssDNA features two 145-base inverted terminal repeats (ITRs) positioned at each end. ITRs have a T-shaped hairpin secondary structure, which plays a crucial role in viral replication. To investigate the impact of ITRs on ssDNA stability, we conducted a DNA denaturation-reannealing assay in 10 mM magnesium acetate, 50 mM potassium acetate, and 20 mM Tris-acetate buffer at pH7.9. Conventional double-stranded DNA (dsDNA) fragments retain a reannealing capability of over 50% for sizes under 8.8 kb, gradually losing this capability as sizes increase; however, dsDNA fragments in rAAV ranging from 0.7 to 6.3 kb did not exhibit a reannealing profile. This suggests that the presence of ITRs at both ends hinders annealing between the complementary strands. These results indicate that ITR structures preferentially induce an ssDNA conformation less than 6.3 kb in size, and that the stability of AAV ssDNA contributes to the viral life cycle, including processes such as infection, replication, and packaging. Considering the size of parvovirus genomes, it appears that their genomes require reversible flexibility in complementary DNA strands; simultaneously, this adaptability needs to be regulated by specific palindromic ITRs at both ends.
A moderately refined and efficient regional seismic damage simulation method considering building irregularity
Authors: Chen Wen-Yue , Yu Ding-Hao , Li Gang 
Published: April 2024

Abstract

Irregular buildings that occupy a certain proportion on regional scales are prone to suffer serious damage from earthquakes due to the influence of lateral-torsional coupling effect. However, the current regional seismic damage simulation methods are mainly based on two-dimensional simplified models, which cannot take into account the spatial characteristics of irregular buildings. In addition, the refined finite-element method is unsuitable for the simulation of a host of buildings on a regional scale. This paper proposes a moderately refined seismic damage simulation method for building groups with high efficiency to consider the spatial irregularity characteristics of structures. The moderately refined layer element model is established to simulate the nonlinear behavior of each story of the building with irregular plan configurations. For the elevation-irregular structures, the proposed model can also be used by properly combining the elements representing various stories in series. Additionally, a simplified approach of considering P-∆ effect is incorporated by adding equivalent lateral forces to nodes and the method for determining the hysteretic parameter and backbone curve parameters of the proposed model is illustrated. Then, a two-level accelerated dynamic analysis method is proposed to reduce computation time for seismic damage simulation in region, which involves a perturbation nonlinear dynamic governing equation for a single structure and an OpenMP parallel solution strategy for structure groups. Finally, the two individual numerical examples and the seismic damage simulation for a region are performed to demonstrate the validity and efficiency of the proposed method.
