Study of deformation behavior of plastic metal materials during laser-assisted micro-imprinting formings
Authors: Meng Siwei , Shi Guangfeng , Lv Hongbing 
Published: February 2024

Abstract
When a large taper angle diamond taper indenter is used for micro-imprinting plastic metals, the stagnation zone is caused by excessive extrusion and friction within the material at the tip of the indenter, which in turn affects the flow characteristics of the material and the quality of the processed surface. In this study, the formation of laser-assisted diamond indenter micro-imprinting stagnation zone mechanism was proposed. The deformation behavior when processing plastic-metal materials using this technique is revealed by numerical simulation. And observed this phenomenon through the hardness distribution of the micro tapered hole cross-section. The results show that when the taper angle of the diamond indenter is greater than 105°, a significant stagnation zone occurs in the material. The initial morphology is jug-shaped, showing periodic changes due to the hard substrate. The average hardness in this region is 91.5 HV, which is significantly lower than the rest of the material. When P = 30 W, the height of the stagnation zone is reduced by 43 μm and the first presence time is extended by 90 μm. The reduction in the friction coefficient leads to a reduction in the width of the interfacial stagnation zone.

Abstract
Severe water pollution due to industrial dye effluents has alarmed the scientific world to unravel a suitable technique and appropriate catalysts for dye removal and wastewater management. In the present work, the adsorbent capacity of ZnO was tuned by calcining ZIF-L, a class of Metal Organic Framework (MOF) at temperatures ranging from 300 °C–600 °C. XRD, FTIR, FESEM-EDX and XPS analysis shows the decomposition of ZIF-L and the nucleation of ZnO at the higher calcining temperatures above 350 °C. The ZIF-L derived ZnO obtained at 420 °C–500 °C exhibited higher CR removal capacity than ZIF-L and ZnO obtained through co-precipitation. The optimized calcining temperature was observed at 480 °C with a maximum Congo Red (CR) dye removal percentage of 94.8%. The adsorption capacities increased from 24.88 mg g−1 to 117.07 mg g−1 as the initial adsorbent dosage decreased from 0.5 g l−1 to 0.1 g l−1. Further, the Langmuir and Freundlich isotherm studies predict the increase in adsorption capacity from 49.09 mg g−1 to 183.98 mg g−1as the initial dye concentration increases from 5 mg l−1 to 50 mg l−1 at the optimal Z480 adsorbent dose of 0.1 g l−1. The result shows that the dye adsorption kinetics and isotherm are well fitted with the Pseudo second order model and the Fruendlich model. The plausible mechanism of dye interaction with the surface of ZnO nanoparticles at different calcining temperatures is also discussed.
Non-singular complexiton, singular complexiton and complex N-soliton solutions of the new extended (3+1)-dimensional Boiti-Leon-Manna-Pempinelli equation
Authors: Wang Kang-Jia , Shi Feng 
Published: February 2024

Abstract
The central target of this work is to extract some novel exact solutions of the new extended (3+1)-dimensional Boiti-Leon-Manna-Pempinelli equation (BLMPE) for the incompressible fluid. By applying the weight algorithm (WA) and linear superposition principle (LSP), we construct two sets of the complexiton solutions, which are the non-singular complexiton and singular complexiton solution via introducing the pairs of the conjugate parameters. In addition, we also explore the complex N-soliton solutions (CNSSs) via the Hirota bilinear equation (HBE) that is developed by the Cole-Hopf transform (CHT). The outlines of the corresponding exact solutions are presented graphically. As far as the information currently available, the derived solutions in this exploration are all new and are expected to enable us to investigate the dynamic characteristics of the considered equation better.

Published: February 2024

Abstract
The clustering of gravitational waves in luminosity distance space is emerging as a promising probe of the growth of structure. Just like for galaxies, its observation is subject to a number of relativistic corrections that affect the measured signal and need to be accounted for when fitting theoretical models to the data. We derive the full expression for the number count of gravitational waves in luminosity distance space, including all relativistic corrections, in ΛCDM and in scalar-tensor theories with luminal propagation of tensors. We investigate the importance of each relativistic effect and the detectability of the total signal by current and planned GW detectors. We consider also supernovae in luminosity distance space, highlighting the differences with gravitational waves in the case of scalar-tensor theories. We carry out a thorough comparison among the number count of gravitational waves and supernovae in luminosity distance space, and that of galaxies in redshift space. We show how the relativistic corrections contain useful complementary information on the growth of perturbations and on the underlying theory of gravity, highlighting the synergy with other cosmological probes.
GFRP continuous RC beams having web openings and externally strengthened with CFRP composites
Authors: Abdulrahman Bassam Qasim 
Published: February 2024

Abstract
With the enormous development of modern buildings, it is highly required to accommodate web openings in continuous reinforced concrete (RC) beams for passing utility service equipment. A wide range of studies had been conducted with regard to this subject. wtCurrent study examined numerically the major effect of the large rectangular web openings in (GFRP) reinforced concrete continuous beams under concentrated loads. Moreover, it investigated the effects of different CFRP strengthening schemes that would retrieve the ultimate capacity of the solid beam. Based on that, the main parameters that had been utilized here are the opening size, opening location and the strengthening scheme. Results showed that openings reduced the ultimate load capacity of the beams and increased the overall deflections. Furthermore, using CFRP sheets to strengthen continuous RC beams including opening retrieved (70%) of the ultimate capacity of continuous RC solid beams especially beams with openings near the external support or midspan. Likewise, using CFRP composites retrieved (48%) of the ultimate capacity of continuous RC solid beams with openings near the interior support. Furthermore, the optimum location for constructing web openings was near the external supports, which was subjected to the lowest values of shear forces and sagging moments and leaded to accommodate greater ultimate loads (85.18 kN) than other beams of other openings location.

Published: February 2024

Abstract
Monitoring the burning surface regression in ground static ignition tests is crucial for predicting the internal ballistic performance of solid rocket motors (SRMs). A previously proposed ultra-sparse computed tomography imaging method provides a possibility for real-time monitoring. However, sample shortages of SRMs highlights the need for monitoring accuracy, especially given the high cost associated with the design and development of SRM systems. Therefore, constructing datasets via regression simulations to compensate for SRM sample shortages is critical. To address this issue, we recommend adopting the level-set method to dynamically track the burning surface by solving partial differential equations (PDEs). The computational cost of numerical solution is prohibitive for scientific applications involving large-scale spatiotemporal domains. The physics-informed neural network (PINN) and neural operator have been used to accelerate the solution of PDE, showing satisfactory prediction performance and high computational efficiency. We designed a physics-guided network, named LS-PhyNet, that couples the potential physical mechanisms of burning surface regression into the deep learning framework. The proposed method is capable of encoding well-established traditional numerical discretization methods into the network architecture to leverage prior knowledge of underlying physics, thus providing the model with enhanced expressive power and interpretability. Experimental results prove that LS-PhyNet can better reproduce the burning surfaces obtained by numerical solution with only small data regimes, providing a new paradigm for real-time monitoring of burning surface regression transients during static ignition tests.
Recent progress in undoped group-IV heterostructures for quantum technologies
Authors: Tai Chia-Tse , Li Jiun-Yun 
Published: February 2024

Abstract
Silicon has been a core material for digital computing owing to its high mobility, stability oxide interface, mature manufacturing technologies for more than half a century. While Moore’s law seems to further advance via various technologies to extend its expiration date, some intractable problems that requires processing times growing exponentially cannot be solved in a reasonable scale of time. Meanwhile, quantum computing is a promising tool to perform calculations much more efficiently than classical computing for certain types of problems. To realize a practical quantum computer, quantum dots on group-IV semiconductor heterostructures are promising due to the long decoherence time, scalability, and compatibility with the Si very-large-scale integrated technology. In this review, we start with the advancement of group-IV undoped heterostructures since 2000 and review carrier transport properties in these undoped heterostructure. We also review the hole effective masses, spin-orbit coupling, and effective g-factors in the Ge-based heterostructures and conclude with a brief summary.

Published: February 2024

ABSTRACT
Pulsed electrical stimulation (PES) is known to affect cellular activities. We previously found PES to human dermal fibroblasts (HFs) promoted platelet-derived growth factor subunit A (PDGFA) gene expression, which enhanced proliferation. In this study, we investigated PES effects on fibroblast collagen production and differentiation into myofibroblasts. HFs were electrically stimulated at 4800 Hz and 5 V for 60 min. Imatinib, a specific inhibitor of PDGF receptors, was treated before PES. After 6 h of PES, PDGFA, α-smooth muscle actin (α-SMA), and collagen type I α1 chain gene expressions were upregulated in PES group. Imatinib suppressed the promoted expression except for PDGFA. Immunofluorescence staining and enzyme-linked immunosorbent assay showed the production of α-SMA and collagen I was enhanced in PES group but suppressed in PES + imatinib group at 48 h after PES. Therefore, PES promotes the production of α-SMA and collagen I in fibroblasts, which is triggered by PDGFA that is upregulated early after PES.

Published: February 2024

Abstract

Motivation
The volume of biomedical data generated each year is growing exponentially as high-throughput molecular, imaging and mHealth technologies expand. This rise in data volume has contributed to an increasing reliance on and demand for computational methods, and consequently to increased attention to software quality and data integrity.

Results
To simplify data verification in diverse data-processing pipelines, we created PipeVal, a light-weight, easy-to-use, extensible tool for file validation. It is open-source, easy to integrate with complex workflows, and modularized for extensibility for new file formats. PipeVal can be rapidly inserted into existing methods and pipelines to automatically validate and verify inputs and outputs. This can reduce wasted compute time attributed to file corruption or invalid file paths, and significantly improve the quality of data-intensive software.

Published: February 2024

Abstract

Motivation
The ongoing expansion in the volume of biomedical data has contributed to a growing complexity in the tools and technologies used in research with an increased reliance on complex workflows written in orchestration languages such as Nextflow to integrate algorithms into processing pipelines. The growing use of workflows involving various tools and algorithms has led to increased scrutiny of software development practices to avoid errors in individual tools and in the connections between them.

Results
To facilitate test-driven development of Nextflow pipelines, we created NFTest, a framework for automated pipeline testing and validation with customizability options for Nextflow features. It is open-source, easy to initialize and use, and customizable to allow for testing of complex workflows with test success configurable through a broad range of assertions. NFTest simplifies the testing burden on developers by automating tests once defined and providing a flexible interface for running tests to validate workflows. This reduces the barrier to rigorous biomedical workflow testing and paves the way toward reducing computational errors in biomedicine.

Authors: Marques Pedro , Emami Anahita , Zhang Guang , Lopes Renato D , Razaghizad Amir , Avram Robert , Sharma Abhinav 
Published: February 2024

Abstract

Aims
The accuracy of voice-assisted technologies, such as Amazon Alexa, to collect data in patients who are older or have heart failure (HF) is unknown. The aim of this study is to analyse the impact of increasing age and comorbid HF, when compared with younger participants and caregivers, and how these different subgroups classify their experience using a voice-assistant device, for screening purposes.

Methods and results
Subgroup analysis (HF vs. caregivers and younger vs. older participants) of the VOICE-COVID-II trial, a randomized controlled study where participants were assigned with subsequent crossover to receive a SARS-CoV2 screening questionnaire by Amazon Alexa or a healthcare personnel. Overall concordance between the two methods was compared using unweighted kappa scores and percentage of agreement. From the 52 participants included, the median age was 51 (34–65) years and 21 (40%) were HF patients. The HF subgroup showed a significantly lower percentage of agreement compared with caregivers (95% vs. 99%, P = 0.03), and both the HF and older subgroups tended to have lower unweighted kappa scores than their counterparts. In a post-screening survey, both the HF and older subgroups were less acquainted and found the voice-assistant device more difficult to use compared with caregivers and younger individuals.

Conclusion
This subgroup analysis highlights important differences in the performance of a voice-assistant–based technology in an older and comorbid HF population. Younger individuals and caregivers, serving as facilitators, have the potential to bridge the gap and enhance the integration of these technologies into clinical practice.

Sex differences in population versus in-hospital use of aortic valve replacement procedures in Spain
Authors: Rosillo Nicolás , Vicent Lourdes , Moreno Guillermo , Vélez Jorge , Sarnago Fernando , Bernal Jose Luis , Bueno Héctor 
Published: February 2024

Abstract

Aims
It is not well known if sex differences in the use and results of aortic valve replacement (AVR) are changing. The aim of the study is to assess the time trends in the differences by sex in the utilization of AVR procedures in hospitals and in the community.

Methods and Results
Retrospective observational analysis using data from the Spanish National Hospitalizations Administrative Database. All hospitalizations between 2016 and 2021 with a main diagnosis of aortic stenosis (International Classification of Diseases-10 codes: I35.0 and I35.2) were included. Time trends in hospitalization, AVRs, and hospital outcomes were analysed. Crude utilization and population-standardized rates were calculated. During the study period, 64 384 hospitalizations in 55 983 patients (55.5% men) with 36 915 (65.9%) AVR were recorded. Of these, 15 563 (42.2%) were transcatheters and 21 432 (58.0%) were surgical. At the hospital level, transcatheter procedures were more frequently performed in women (32.3% vs. 24.2%, P &lt; 0.001), and surgical in men (42.9% vs. 32.5%, P &lt; 0.001) but at the population level, surgical and transcatheter aortic valve replacements (TAVRs) were used more frequently in men (12.6 surgical and 8.0 transcatheter per 100 000 population) vs. women (6.4 and 5.8, respectively; P &lt; 0.001 for both comparisons). Transcatheter procedures shifted from 17.3% in 2016 to 38.0% in 2021, overtaking surgical procedures in 2018 for women and 2021 for men.

Conclusions
TAVR has displaced surgical aortic valve replacement (SAVR) as the most frequent AVR procedure in Spain by 2020. This occurred earlier in women, who, despite the greater weight of their age group in the older population, received fewer AVRs, both SAVR and TAVR.
Surgical strategies for benign acquired tracheoesophageal fistula
Authors: Zeng Ao , Liu Xiaogang , Shaik Mohammed Saud , Jiang Gening , Dai Jie 
Published: February 2024

Abstract

OBJECTIVES
Tracheoesophageal fistula (TEF) is characterized by abnormal connectivity between the posterior wall of the trachea or bronchus and the adjacent anterior wall of the oesophagus. Benign TEF can result in serious complications; however, there is currently no uniform standard to determine the appropriate surgical approach for repairing TEF.

METHODS
The PubMed database was used to search English literature associated with TEF from 1975 to October 2023. We employed Boolean operators and relevant keywords: ‘tracheoesophageal fistula’, ‘tracheal resection’, ‘fistula suture’, ‘fistula repair’, ‘fistula closure’, ‘flap’, ‘patch’, ‘bioabsorbable material’, ‘bioprosthetic material’, ‘acellular dermal matrix’, ‘AlloDerm’, ‘double patch’, ‘oesophageal exclusion’, ‘oesophageal diversion’ to search literature. The evidence level of the literature was assessed based on the GRADE classification.

RESULTS
Nutritional support, no severe pulmonary infection and weaning from mechanical ventilation were the 3 determinants for timing of operation. TEFs were classified into 3 levels: small TEF (&lt;1 cm), moderate TEF (≥1 but &lt;5 cm) and large TEF (≥5 cm). Fistula repair or tracheal segmental resection was used for the small TEF with normal tracheal status. If the anastomosis cannot be finished directly after tracheal segmental resection, special types of tracheal resection, such as slide tracheoplasty, oblique resection and reconstruction, and autologous tissue flaps were preferred depending upon the site and size of the fistula. Oesophageal exclusion was applicable to refractory TEF or patients with poor conditions.

CONCLUSIONS
The review primarily summarizes the main surgical techniques employed to repair various acquired TEF, to provide references that may contribute to the treatment of TEF.
Cross-talk between immunity and behavior: insights from entomopathogenic fungi and their insect hosts

Published: February 2024

Abstract
Insects are one of the most successful animals in nature, and entomopathogenic fungi play a significant role in the natural epizootic control of insect populations in many ecosystems. The interaction between insects and entomopathogenic fungi has continuously coevolved over hundreds of millions of years. Many components of the insect innate immune responses against fungal infection are conserved across phyla. Additionally, behavioral responses, which include avoidance, grooming, and/or modulation of body temperature, have been recognized as important mechanisms for opposing fungal pathogens. In an effort to investigate possible cross-talk and mediating mechanisms between these fundamental biological processes, recent studies have integrated and/or explored immune and behavioral responses. Current information indicates that during discrete stages of fungal infection, several insect behavioral and immune responses are altered simultaneously, suggesting important connections between the two systems. This review synthesizes recent advances in our understanding of the physiological and molecular aspects influencing cross-talk between behavioral and innate immune antifungal reactions, including chemical perception and olfactory pathways.
