In silico analysis of a hierarchical microfluidic vascular network: Detecting the location of angiogenic sprouting
Authors: Asiyabi Milad Mahdinezhad , Vahidi Bahman 
Published: October 2022

AbstractLack of oxygen is one of the leading causes of failure in engineered tissue. Therefore, angiogenesis will be necessary for the survival of larger tissues in vivo. In addition, a proper lymphatic system that plays an essential role in relieving inflammation and maintaining tissue homeostasis is of great importance for tissue regeneration and repair. Many biomechanical parameters are involved in controlling angiogenesis and capillary network generation, which are challenging to study and control in experimental studies or in vitro. In the present study, using numerical modeling, the effect of various geometric and biomechanical parameters in creating suitable conditions for angiogenesis was investigated. Furthermore, sprouting points were predicted using flow dynamics. For this purpose, a porous scaffold, flow channels with parametric geometry that followed Murray's law, and a drainage channel were considered. Results suggested that the geometry of the microfluidic channels and the characteristics of the vessel wall and scaffold plays a complementary role in determining the transmural pressure. It was found that a twofold increase in the vascular hydraulic conductivity can reduce the minimum transmural pressure by up to 28% and increase the drainage flow rate by 44%. In addition, the minimum magnitude of transmural pressure tends to zero for scaffold's hydraulic conductivity values smaller than 10−11 m3 s kg−1. The results of this study can be used in optimizing the design of the relevant microfluidic systems to induce angiogenesis and avoid leakage in the constructed implantable tissue.

Published: October 2022

SummaryIn the field of ear acupoint therapy in traditional Chinese medicine, many diseases can be treated through ear acupoint acupuncture, buried needle, bleeding, ear acupoint compression, massage, electric stimulation, and other programs. To achieve this goal, the positioning of the earhole feature point region is required. Based on the active appearance model, this article proposes an automatic identification feature point scheme through 168 datasets of data (including data collected based on standard equipment and ordinary mobile phones) collected from Hangzhou Normal University, China. The experimental results show that the average distance error of 91 feature points is less than 6 pixels, which can replace the identification work of TCM ear acupoint doctors.

Authors: Zhou Yousheng , Liu Kexin , Vijayakumar Pandi 
Published: October 2022

SummaryWith the popularity of cloud computing, more and more users store sensitive information in cloud servers. In order to protect the data over the cloud server, symmetric encryption with keyword search has been developed and the phrase search has been proposed subsequently to overcome the inefficiency produced by single/multi‐keyword search. However, most existing phrase search schemes fails to support fault‐tolerant search which is essential to users. Therefore, this paper proposes a fault‐tolerant dynamic phrase search scheme with forward privacy and backward privacy (FTPS). Piecewise Linear Chaotic Map and minhash function are used to blur information, and Bloom filter based index is constructed to realize efficient search and dynamic update simultaneously. Security analysis proves that FTPS can properly preserve the privacy of search user, and experimental results show that FTPS is practical.

Authors: Cicioğlu Murtaza , Çalhan Ali , Miah Md Sipon 
Published: October 2022

SummaryThe Internet of Things (IoT) concept increases the spectrum demands of mobile users in wireless communications because of the intensive and heterogeneous structure of IoT. Various devices are joining IoT networks every day, and spectrum scarcity may be a crucial issue for IoT environments in the near future. Cognitive radio (CR) is capable of sensing and detecting spectrum holes. With the aim of CR, more powerful IoT devices will be constructed in such crowded wireless environments. Also, dynamic and ad‐hoc CR networks have not a fixed base station. Therefore, CR capable IoT (CR‐based IoT) device approach with routing capabilities will be a solution for future IoT environments. In this study, spectrum aware Ad hoc on‐demand distance vector routing protocol is proposed for CR‐based IoT devices in IoT environments. For the performance analysis of the proposed method, various network scenarios with different idle probability have been performed and throughput and delay results for different offered loads have been analyzed.

Published: October 2022

AbstractElectrochemical properties of metal oxide have a strong correlation with the crystalline structures. In this work, the effect of calcination temperature on the phase evolution and electrochemical properties of Sm2O3 was systematically evaluated. The results demonstrate that the sample calcinated at 700 °C (SM‐700) is composed of a pure cubic phase while it begins to convert into a monoclinic phase at a temperature above 800 °C and fully converts into a monoclinic phase at 1100 °C. Moreover, the evolution process causes atomic redistribution, and more oxygen vacancies are formed in cubic phase Sm2O3, contributing to the improved ionic conductivity. The ionic conductivity of 0.138 S cm−1 and maximum power density of 895 mW cm−2 at 520 °C are achieved using SM‐700 as electrolyte for protonic ceramic fuel cell (PCFC). The cubic structure remains stable in the durability testing process and the SM‐700 based fuel cell delivers enhanced stability of 140 mW cm−2 for 100 h. This research develops a calcination evolution process to improve the ionic conductivity and fuel cell performance of the Sm2O3 electrolyte for stable PCFC.
Coarsening‐induced disappearing droplets contribute to condensation

Published: October 2022

AbstractCondensation heat transfer is widely used in water and energy systems. Despite being extensively studied, since 1973, the models for dropwise condensation have strongly relied on the droplet size distribution. In this study, we report that the classical models underestimate the heat transfer performance of dropwise condensation on a hydrophilic liquid‐infused surface, on which the meniscus‐mediated coarsening droplets lead to a previously unachieved droplet coverage ratio down to 30%. We found that the time‐averaged classical models have overlooked the coarsening‐induced disappearing droplets. Moreover, these models cannot be used to determine the instantaneous heat transfer coefficient on the shedding‐induced water‐free surface under steam condensation. Thus, a dynamic model is developed for dropwise condensation by considering the disappearing droplets induced by both coarsening and shedding, which shows good agreement with the experimental validation. Such a dynamic model provides a theoretical foundation to design surfaces for condensation, giving rise to an advanced design guideline for water and energy systems.

Published: October 2022

AbstractDue to its characteristics of noncontact, non‐damage, high flux, and easy‐to‐achieve flexible manipulation, optically induced dielectrophoresis (ODEP) technology has been employed to manipulate microspherical biological particles, including separation, enrichment, capture, arrangement, and fusion. However, in nature, biomolecules are morphologically diverse, and some of them are rodlike. In order to illustrate the electrodynamics of rodlike particles under the action of ODEP, a transient multi‐physical field coupling model of ODEP chip under the hypothesis of electrical double layer thin layer was established in this paper. The arbitrary Lagrangian–Eulerian method is used to track single‐rod particle in the strong coupled flow field and electric field simultaneously. The influence of several key factors, including the applied alternating current (AC) electric voltage, the width of optical bright area, and the initial position of particle, on the trajectory of particle center was analyzed in positive dielectrophoresis (DEP) action and negative DEP action, respectively. Especially, the planar motion process of rodlike particles was discussed together. The research results reveal the electrodynamics behavior of rodlike particles based on the action of ODEP, which may provide theoretical support for the further design of rodlike biological cells manipulation chip based on AC ODEP technology in the future.

Published: October 2022

AbstractThis study provides the first survey of Brazilian magnetic susceptibility (MS) data from varying archaeological and geological contexts, including open‐air sites, quartzite, and limestone rockshelters, and Amazonian dark earths. Our MS analyses associated with archaeological findings allow us to propose MS values as proxies of intense anthropogenic burning activities for archaeological sites with (i) systematic use of large hearth lit in the same places; (ii) systematic burns and highly diverse uses; (iii) higher diversity use with few fire activities and knapping playing an essential role; and (iv) incipient human activities and the initial use of the archaeological site. Our data are limited to understanding anthropogenic burning activities and cannot be extended to reveal other archaeological aspects. The results have implications for understanding human occupation in a large area with numerous archaeological sites. This study was the first step in distinguishing archaeological fires from natural fires and provided a new perspective for further research that attempts to identify distinct types of human fires.
Toward a more sustainable environment: Understanding why and when green training promotes employees' eco‐friendly behaviors outside of work

Published: October 2022

AbstractAlthough green training has been shown in past research to promote environmentally responsible behaviors at work, scholars have paid less attention to its influence on employees' eco‐friendly behaviors outside of work. This omission is critical because confining green training research to the work domain obscures its benefits in promoting employees' pro‐environmental behaviors beyond the workplace, and thus its role in supporting organizational efforts to conserve the natural environment. To address this gap, we examine the direct and indirect (via connectedness to nature) relationships between green training and employees' eco‐friendly behaviors outside of work, including consumption of eco‐friendly products, reuse of items and materials, and reduced consumption of resources such as water, electricity, and paper. We also examine the moderating influence of intrinsic spirituality on the direct link between green training and connectedness to nature, as well as the indirect link between green training and eco‐friendly behaviors beyond the workplace. Using time‐lagged, multisource data, we find support for our hypotheses. Our findings advance knowledge on the important yet largely overlooked role of green training in shaping employees' environmentally responsible behaviors outside of the workplace.

AbstractIntroductionC‐reactive protein (CRP) and cytokines levels could alter in patients with coronavirus disease (COVID‐19) due to the inflammatory response caused by the virus. This analysis aimed to assess the relationship between the CRP levels and the levels of various cytokines in COVID‐19 patients.Materials and MethodsWe searched the databases of PubMed, Cochrane, and Web of Science for relevant articles on May 29th, 2021. Applying the inclusion/exclusion criteria, the retrieved records underwent two‐phase screenings; first, a title/abstract screening process, and then, a full‐text screening to find the eligible studies. Data for study variables were extracted, including the CRP levels and the levels of all reported cytokines. A strong and significant relationship between Interleukins and CRP was defined as:p ≤ 0.05, 0.7 ≤ r ≤ 1.ResultsIn this study, 103 studies were included for systematic review and correlation analysis. The aggregate mean and SD of study variables were calculated and reported. The correlation between Interleukins and CRP was measured using correlation coefficient (r). It appeared that interleukin (IL)‐10 has a moderate and significant relationship with CRP (p ≤ 0.05,r = 0.472). IL‐10 predicted almost 10% of CRP changes.ConclusionThis correlation analysis suggests IL‐10 is moderately correlated with CRP levels in patients with COVID‐19 infection. A better understanding of the pro‐inflammatory markers could contribute to the implementation of therapeutic and preventive approaches. More prospective studies are suggested to explore the relationship between CRP and cytokines as potential markers for the early identification of COVID‐19 progression and severity.

Published: October 2022

AbstractMinor girls in Africa face challenges in accessing high‐quality contraceptive and abortion services because laws and policies are not child‐friendly. Many countries maintain restrictive laws, policies, or hospital practices that make it difficult for minors to access contraception and safe abortion even when the pregnancy would risk their life or health. Further, the clinical guidelines on contraceptive and abortion care are silent, vague, or ambiguous regarding minors' consent. African states should remedy the situation by ensuring that clinical guidelines integrate child rights principles and standards articulated in child rights treaties to enable health providers to facilitate full, unencumbered access to contraceptive and abortion care for minor girls. A sample of clinical guidelines is analyzed to demonstrate the importance of explicit, consistent, and unambiguous language about children's consent to ensure that healthcare workers provide sexual and reproductive health care in a manner that respects child rights.
The impact of e‐commerce city pilot on the spatial agglomeration of high‐end service industry in China
Authors: Pan Xuwen , Zhou Cai 
Published: October 2022

AbstractWe employ the data of 290 cities in China from 2006 to 2019 as a research sample and use the Multi‐period DID method to test the policy shock of National E‐commerce Demonstration Cities (NEDC) pilots on high‐end service industry agglomeration. We find that after becoming pilot cities, the specialized agglomeration level of its high‐end service industry increases by about 14.1% on average, and the diversified agglomeration level decreases by about 2.7% on average. And NEDC policy can affect the spatial agglomeration of high‐end service industry through three channels: Enhancing the inclusiveness of digital finance, improving the degree of market competition, and promoting regional innovation ability. Moreover, NEDC policy has the characteristics of spatial heterogeneity. NEDC policy has a significant spillover effect on the specialized agglomeration of high‐end service industry in the first‐tier cities, while the second‐tier cities show the characteristics of diversification dispersion. In addition, NEDC policy has a more obvious impact on the agglomeration effect of high‐end service industry under the radiation and driving effect of megalopolis.

Published: October 2022

AbstractIntroductionAs adolescents begin to expand their social networks beyond their family, they turn increasingly to their peers for support. Parenting practices present in the parent–child dyad are likely to extend to peer dyads. However, when considering the process involved in the transmission from parenting practices to friendships, the mediating role of parent–child relationships remains unclear. The current study explored the mediating effect of mother–adolescent relationship quality in the association between perceived maternal parenting practices (i.e., autonomy support and psychological control) and friendship quality using a three‐wave longitudinal design, and also examined whether adolescents' gender moderates these associations.MethodsA sample of 344 Chinese adolescents (12.01 to 15‐year‐old at Wave 1, M = 13.08, SD = 0.39; 153 boys and 191 girls) filled out questionnaires on perceived maternal parenting practices, mother–adolescent relationship quality, and friendship quality, separately in three waves.ResultsPerceived maternal autonomy support was associated with positive friendship quality through positive mother–adolescent relationship quality. However, perceived maternal psychological control was not associated with negative friendship quality. Moreover, marginal gender differences were only found in the associations between autonomy support and positive mother–adolescent relationship quality.ConclusionsThese findings demonstrate the spillover effects existed only between autonomy support and positive friendship quality, and highlight the importance of positive mother–adolescent relationship quality when promoting positive friendship quality.
TRACP‐5b/BAPScore After 3 Months of Treatment With CombinedSERM/E2Therapy Can Predict Changes in Lumbar Spine Bone Mineral Density After 1 Year of Treatment in Early Postmenopausal Osteopenia

Published: October 2022

ABSTRACTAlthough changes in bone mineral density (BMD) are important indexes in osteoporosis treatment, no markers are available to predict them. Given the importance of assessing the therapeutic windows of antiresorptives, we explored potential biomarkers of bone remodeling in patients receiving treatment for osteopenia. Postmenopausal women with osteopenia (defined as a lumbar BMDT‐score <−1.0 standard deviation (SD) below that of a reference population but >−2.5 SD) were administered estradiol 1 mg/d and bazedoxifene 20 mg/d. After 3 months of treatment, we evaluated their ratio of serum bone‐specific tartrate‐resistant acid phosphatase to bone‐specific alkaline phosphatase (TRACP‐5b/BAP), which is widely used for evaluating bone turnover in postmenopausal patients with osteoporosis in Japan because their minimum significant changes are smaller than other bone turnover markers such as carboxy‐terminal collagen cross‐links (CTX) or N‐terminal propeptide of type I procollagen (P1NP) and thus, accurately reflect bone turnover. After 1 year of treatment, we assessed changes in lumbar BMD. The cut‐off TRACP‐5b/BAP scores for a ≤−2% decrease and ≥2% increase in lumbar spine BMD were 38.4 and 29.0, respectively. The TRACP‐5b/BAP scores were associated with significantly greater areas under the curve than the other evaluated parameters. These results suggest that the TRACP‐5b/BAP score after 3 months of osteopenia treatment can predict changes in lumbar BMD after 1 year of treatment. Moreover, a receiver operating characteristic curve analysis of TRACP‐5b/BAP scores after 3 months of antiresorptive therapy and percent changes in BMD at 1 year revealed that the TRACP‐5b/BAP score, as an index of the balance between bone resorption and formation markers, has the potential to serve as a modulator of the anabolic window reflective of bone remodeling. This study's findings also suggested a role for TRACP‐5b/BAP score as a predictor of a non‐response to antiresorptive therapy, thus offering health economic implications for osteoporosis treatment. © 2022 The Authors.JBMR Pluspublished by Wiley Periodicals LLC on behalf of American Society for Bone and Mineral Research.
Hypoxia‐induced reprogrammed myoblasts enhance the formation of neuromuscular junctions: A pioneer study
Authors: Tolsma Rachael , Pan Haiying , Harris Loyall , Spitsbergen John M. , Li Yong 
Published: October 2022

AbstractWe previously reported that muscle cells could reprogram into progenitors after traumatic injuries. These injury‐induced muscle stem cells (iMuSCs) have increased migration and differentiation capacities, including neuronal differentiation. Recent studies in our laboratory suggest that the hypoxia‐induced by tissue injury plays an essential role in the reprogramming process of muscle cells. We hypothesize that muscle cells reprogrammed with hypoxia have increased neuronal differentiation potentials and the neuronal differentiation extends into the formation of neuromuscular junction (NMJ)‐like structures. In this study, C2C12 myoblasts were cultured under hypoxic conditions and subsequently in neural differentiation media to generate neurospheres, and then with muscle differentiation media to induce NMJ‐like structure formation. Hypoxia‐induced muscle cells also produced more robust NMJs compared to controls after intramuscular cell transplantation. Our results suggest hypoxia plays a role in the reprogramming of muscle stem cells, which may have the potential to form neuromuscular junctions and ultimately contribute to functional muscle healing.
