Published: March 2024

AbstractSpinal cord injury, traumatic brain injury, and neurosurgery procedures usually lead to neural tissue damage. Self‐assembled peptide (SAP) hydrogels, a type of innovative hierarchical nanofiber‐forming peptide sequences serving as hydrogelators, have emerged as a promising solution for repairing tissue defects and promoting neural tissue regeneration. SAPs possess numerous features, such as adaptable morphologies, biocompatibility, injectability, tunable mechanical stability, and mimicking of the native extracellular matrix. This review explores the capacity of neural cell regeneration and examines the critical aspects of SAPs in neuroregeneration, including their biochemical composition, topology, mechanical behavior, conductivity, and degradability. Additionally, it delves into the latest strategies involving SAPs for central or peripheral neural tissue engineering. Finally, the prospects of SAP hydrogel design and development in the realm of neuroregeneration are discussed.
Evaluating the performance of corn peptone in preventing the corrosion of mild steel immersed in HCl
Authors: Rabizadeh Taher 
Published: March 2024

AbstractThe effects of biodegradable corn peptone on the corrosion behavior of mild steel in 0.1M HCl were evaluated. The results from the weight loss experiments indicate that changing the amount of corn peptone from 50 to 500 ppm considerably decreased the corrosion rate of the coupons from 28.24 to 4.67 mpy. However, heating the solutions had negative effects on this trend. According to the calculations, dissolving the inhibitor modified the thermodynamic parameters of the corrosion phenomenon. In addition, the adsorption of corn peptone was best fitted with the Langmuir isotherm. The Tafel polarization plots revealed that the presence of corn peptone decreased the corrosion current density from 134.9 to 6.7 µA cm−2. This was compatible with the electrochemical impedance spectroscopy data. Furthermore, X‐ray photoelectron spectroscopy analysis confirmed the adsorption of the tested peptone on the surface of the working electrodes, which based on the atomic force microscope images, reduced the surface roughness of the specimens.
Study on superhydrophobicity and excellent corrosion resistance of a novel Ni‐SiC nanocomposite coating
Authors: Liu Jianguo , Bai Yujie , Xing Xiao , Cui Gan 
Published: March 2024

AbstractCarbon steel is widely used, but it is prone to corrosion, which can lead to safety accidents. In this study, a novel Ni‐SiC coating was synthesized on the surface of carbon steel using a one‐step electrodeposition method, and the influence of electrodeposition parameters on the wettability of the coating was investigated. This coating possesses abundant micro‐nanostructures on its surface, which, after being placed in a vacuum drying environment for 2 weeks, endows it with superhydrophobic characteristics. Due to its superhydrophobic properties and the rich micro‐nanostructures, the corrosion current density of this coating is 1/18.95 that of bare steel. After immersion in a corrosive medium for some time, the polarization resistance value of the coated sample was observed to be 13.05 times greater than that of bare steel, demonstrating its remarkable ability to enhance the corrosion resistance of the surface. The results of this study can provide a reference for the anticorrosion work on carbon steel.
The effects of government subsidy on manufacturers' technology sharing behavior with risk consideration
Authors: Lin Yufei , Zeng Weijun 
Published: March 2024

AbstractThis study focuses on how consumer subsidy (COS) and manufacturer subsidy (MAS) influence a focal risk‐averse manufacturer's technology sharing, who balances between risk pooling effect and competition effect along with new entry for decision. When consumers' uncertain valuations are highly positively (or negatively) correlated for the manufacturers' products, the higher COS and the higher MAS can (or cannot) enhance the manufacturer's technology sharing because the risk pooling effect is strong (or weak), but the competition effect is weak (or strong). Only when the risk pooling effect dominates the competition effect, COS is more conducive than MAS to promoting technology sharing.
Reconstructing the life histories of a noble couple from the Joseon period, Korea, based on skeletal evidence and historical records

Published: March 2024

AbstractThis study is an osteobiography of a noble couple who were members of the “ruling elite” in the 18th‐century Joseon period, Korea. The archaeological context and historical records indicate that the couple lived and died during a period marked by strict observance of social hierarchy. The husband's skeleton exhibits clear evidence of craniosynostosis and spinal scoliosis. In particular, congenital craniosynostosis of the skull likely caused deformities in his craniofacial morphology during his lifetime. The physical deformities and discomforts revealed by his craniofacial and vertebral skeleton shed light on the documented passivity and frequent disruptions to his government positions. Meanwhile, his wife's age at death, 93 years, is exceptionally long. The osteological investigation suggests that she seems to have lived without severe stressors. Her skeletal remains show no evidence of occupational stress or chronic disease. Until now, our understanding of the Joseon period nobility has predominantly relied on artifacts and summaries of the deceased's life discovered in tombs, as well as written documents such as diaries, evaluation records, and letters. This study reconstructs the lives of this couple through osteological evidence, historical records, and social context. This holistic approach will provide a novel perspective for a more comprehensive understanding of the lives of nobility and intellectuals of the period.

Published: March 2024

AbstractObjectiveTo determine if absorbable gelatin sponge (AGS) can be used to assess the posttympanoplasty microbiome and otic antibiotic exposure.Study DesignProspective.SettingTertiary hospital.MethodsPatients undergoing tympanoplasty were prospectively enrolled. Intraoperatively, AGS was applied to the medial ear canal/tympanic membrane (TM) for 1 minute after canal incision, then saved for analysis. Ear canals were packed with AGS at the end of surgery. Otic ofloxacin was administered until the first postoperative visit, when AGS was collected. Microbial presence was assessed by culture. Ofloxacin levels were assessed by liquid‐chromatography mass‐spectrometry.ResultsFifty‐three patients were included. AGS was collected in 92.9% of patients seen within 21 days compared to 70.8% of those seen at 22 to 35 days. At surgery, AGS yielded bacteria and fungi in 81% and 11%, respectively, includingStaphylococcusspecies (55%) andPseudomonasspecies (25%). Postoperatively, AGS yielded bacteria in 71% and fungi in 21% at the meatus, (staphylococci 57% and pseudomonas 25%). TM samples yielded bacteria in 69%, fungi in 6%, staphylococci in 53%, and pseudomonas in 19%. Ofloxacin concentration at the meatus was 248 μg/mL (95% confidence interval [CI]: 119‐377) and at the TM was 126 μg/mL (95% CI: 58‐194). Ofloxacin‐resistant colonies were found in 75% of patients.ConclusionAnalysis of AGS is a viable technique for noninvasively studying healing metrics posttympanoplasty, including the microbiome and otic antibiotic exposure. Despite exposure to a high concentration of quinolones, the tympanoplasty wound is far from sterile, which may impact healing outcomes.
A meta‐analysis of SES framework case studies: Identifying dyad and triad archetypes

Published: March 2024

Abstract

There is a need to synthesize the vast amount of empirical case study research on social‐ecological systems (SES) to advance theory. Innovative methods are needed to identify patterns of system interactions and outcomes at different levels of abstraction. Many identifiable patterns may only be relevant to small sets of cases, a sector or regional context, and some more broadly. Theory needs to match these levels while still retaining enough details to inform context‐specific governance. Archetype analysis offers concepts and methods for synthesizing and explaining patterns of interactions across cases. At the most basic level, there is a need to identify two and three independent variable groupings (i.e. dyads and triads) as a starting point for archetype identification (i.e. as theoretical building blocks). The causal explanations of dyads and triads are easier to understand than larger models, and once identified, can be used as building blocks to construct or explain larger theoretical models.

We analyse the recurrence of independent variable interactions across 71 quantitative SES models generated from qualitative case study research applying Ostrom's SES framework and examine their relationships to specific outcomes (positive or negative, social or ecological). We use hierarchical clustering, principal component analysis and network analysis tools to identify the frequency and recurrence of dyads and triads across models of different sizes and outcome groups. We also measure the novelty of model composition as models get larger. We support our quantitative model findings with illustrative visual and narrative examples in four case study boxes covering deforestation in Indonesia, pollution in the Rhine River, fisheries management in Chile and renewable wind energy management in Belgium.

Findings indicate which pairs of two (dyads) and three (triads) variables are most frequently linked to either positive or negative, social or ecological outcomes. We show which pairs account for most of the variation of interactions across all the models (i.e. the optimal suite). Both the most frequent and optimal suite sets are good starting points for assessing how dyads and triads can fulfil the role of explanatory archetype candidates. We further discuss challenges and opportunities for future SES modelling and synthesis research using archetype analysis.

Ensemble regression method for predicting the dependence of electrical resistance on the elongation of polymer composite materials
Authors: Stepashkina Anna , Yakushev Aleksei 
Published: March 2024

AbstractComposite materials are actively used as protection against electromagnetic fields, as conductors and to remove excess heat from microcircuits and boards. Such products are often subjected to mechanical stress during operation, and stretched polymer‐film composite materials suffer from deterioration in electrical conductivity, which leads to loss of electrically conductive properties. In this work, the effect of mechanical deformation (stretching) on electrical conductivity properties was studied. A predictive model was built based on Boltzmann statistics, which allows predicting the loss of electrically conductive properties when materials are under mechanical stress. The resulting model was refined by introducing coefficients calculated using an ensemble regression machine learning method. The mean absolute percentage error of the predicted electrical conductivity value for the materials under mechanical stress is about 5%–20%.Highlights

Published: March 2024

AbstractPolymer adhesives have considerable mechanical and environmental privileges; however, their high price makes them uncommercial for common uses. This study investigates the incorporation of recycled or byproduct fillers in epoxy resin‐based composites to assess their mechanical properties, environmental impacts, and cost efficiency. The fillers examined include fly ash, glass powder, slag, silica powder, and limestone powder. Tensile, compressive, and fracture tests were conducted on composites with various filler proportions (0%–80% by weight). From microstructure observations, round (fly ash, glass powder) and rough (slag, silica, and limestone powder) morphologies are seen. Also, it is seen that all the fillers are well distributed in the matrix; with the increase of filler content, the air voids increase. The tensile and compressive results indicate that adding fillers improves the composite's strengths, with up to a 20% increase compared to neat epoxy resin. However, when filler contents exceed 40%, the strengths decrease. Fracture toughness values also decrease with increasing filler content. Comparing the results with those of other studies indicates the similarity of trends. Cost‐strength and CO2eq‐strength curves were evaluated to assess the financial and environmental aspects. The composites show potential for cost efficiency but may have some environmental drawbacks compared to traditional construction materials like cement concrete.Highlights

Published: March 2024

AbstractAimInmates in correctional institutions experience higher rates of suicide attempt (SA), suicidal ideation (SI), and nonsuicidal self‐injury (NSSI) than the general population. This study aimed to examine the association between the Big Five personality traits and suicide‐related behavior, and to estimate the prevalence rate of such behaviors among Japanese institutionalized youth.MethodsThe participants were 436 youths who had been admitted to four juvenile classification homes (JCHs) between September 2021 and March 2023; they were asked to respond to a self‐report questionnaire after obtaining informed consent.ResultsA total of 8.1% and 19.3%, 29.4% and 44.7%, and 46.3% and 75.3% of males and females had experienced SA, SI, and NSSI in their lifetime, respectively. Females reported significantly higher instances of suicide‐related behaviors than males considering all suicide‐related behaviors. Logistic regression analyses revealed that neuroticism significantly increased the odds ratios for SA, SI, and NSSI on controlling for sex, age, and number of admissions to JCHs. For NSSI, the odds ratio for agreeableness was significantly lower than 1, indicating a lower probability of NSSI.ConclusionThe findings of our study demonstrate that neuroticism, one of the Big Five traits, was consistently and significantly associated with all suicide‐related behaviors, including SA, SI, and NSSI, among youth offenders, while agreeableness was found as a protective factor only against NSSI. The results of this study might help correctional officers identify justice‐involved youth at higher risk for suicide and allow the development of early interventions to prevent suicide.
Roles of Metal Nanoparticles for Supercapacitors: A Review
Authors: Yan Ailan , Wang Xinchang , Cheng Jipeng 
Published: March 2024

AbstractRecent research on supercapacitors (SCs) has been attractive due to the potential application in a variety of fields related to energy storage. Electrode materials play a very important role for the performance of SCs and various metal nanoparticles are involved in the SC electrodes. In this paper, the roles of metal nanoparticles for SCs are reviewed and discussed. They can serve as a dopant to modify the surface of electrode materials, or be embedded in a composite to effectively reduce the resistance and lead to an enhanced specific capacitance. Some metal nanoparticles can be also employed as electrode materials directly, but easily being oxidized. Metallic nanoparticles can even act as current collectors, especially for these noble metals with excellent stability and high conductivity. Nanoporous metals prepared by dealloying and electrochemical method can be used as both pseudocapacitive materials and current collector of SCs. Some important experimental data on this issue are summarized. A brief discussion on the future directions, challenges and opportunities in this topic is also provided.
Variable gut pH as a potential mechanism of tolerance to Bacillus thuringiensis subsp. israelensis toxins in the biting midge Culicoides sonorensis
Authors: Osborne Cameron J , Su Tianyun , Silver Kristopher S , Cohnstaedt Lee W 
Published: March 2024

AbstractBACKGROUNDToxins of Bacillus thuringiensis subsp. israelensis (Bti) are safer alternatives for controlling dipteran pests such as black flies and mosquitoes. The biting midge Culicoides sonorensis (Diptera: Ceratopogonidae) is an important pest of livestock in much of the United States and larval midges utilize semi‐aquatic habitats which are permissive for Bti product application. Reports suggest that Bti products are ineffective at killing biting midges despite their taxonomic relation to black flies and mosquitoes. Here, we investigate the toxicity of a Bti‐based commercial insecticide and its active ingredient in larval Culicoides sonorensis. A suspected mechanism of Bti tolerance is an acidic larval gut, and we used a pH indicator dye to examine larval Culicoides sonorensis gut pH after exposure to Bti.RESULTSThe lethal concentration to kill 90% (LC90) of larvae of the commercial product (386 mg/L) was determined to be almost 10 000 times more than that of some mosquito species, and no concentration of active ingredient tested achieved 50% larval mortality. The larval gut was found to be more acidic after exposure to Bti which inhibits Bti toxin activity. By comparison, 100% mortality was achieved in larval Aedes aegypti at the product's label rate for this species and mosquito larvae had alkaline guts regardless of treatment. Altering the larval rearing water to alkaline conditions enhanced Bti efficacy when using the active ingredient.CONCLUSIONWe conclude that Bti is not practical for larval Culicoides sonorensis control at the same rates as mosquitos but show that alterations or additives to the environment could make the products more effective. © 2024 Society of Chemical Industry.

AbstractMicroaerial vehicles (MAVs) have achieved rapid advancement and vast applications. Energy efficiency and friction loss are common problems of MAVs, and exploring novel structural design and enhancing flight performance are critical research directions. Here, a bionic‐inspired single‐rotor MAV with a foldable wing is fabricated by imitating winged achene in nature. The structural design of the wing based on origami principle, overall aerodynamic modeling analysis, kinematic analysis, and control system design is carried out. The prototype weighs 75 g and equipped with only one motor, achieved the desired flight attitude of vertical takeoff and landing, hovering and horizontal flight, and so forth. During nonflight, the wings fold down can reduce 70% storage area for easier transportation. The vehicle combines high flight efficiency with compactness, superior stability, simple structure, economical manufacturing cost, low flight noise, and spin deceleration safety protection, which has good potential for application in the aerial vehicle fields.

Abstract

Background
Individual reports have described lymphoproliferative disorders (LPDs) and cutaneous lymphomas emerging after administration of the COVID-19 vaccine; however, the relationship between reactions and vaccine types has not yet been examined.

Objective
Determine if there are cases of cutaneous LPDs associated with certain COVID-19 vaccines and their outcomes.

Methods
We analysed PubMed, the Vaccine Adverse Events Reporting System (VAERS), and our database for instances of biopsy-proven LPDs following COVID-19 vaccines.

Results
Fifty cases of biopsy-proven LPDs arising after COVID-19 vaccination were found: 37 from medical literature, 11 from VAERS and two from our institution. Geographical distribution revealed the most cases in the United States, Italy, and Greece, with single cases in Spain, Colombia, Canada, Japan, and Romania. The average age of patients was 53; with a slight male predominance (male-to-female ratio of 1.5:1). The Pfizer-BioNTech vaccine was associated with LPDs in 36/50 (72%) cases, aligning with its 70% share of the global vaccine market. Histopathology revealed CD30+ in 80% of cases. The most prevalent form of LPD was lymphomatoid papulosis (LyP, 30%). All reported cases produced favourable outcomes (either complete or near-complete remission). Therapeutic approaches ranged from observation to treatment with steroids, methotrexate, or excision.

Conclusion
LPDs after COVID-19 vaccination appear in the context of the same vaccines (proportionally to their global market shares), share clinical and pathological findings, and have indolent, self-limited character.

AbstractThe pathogen‐based diseases are prime concern for modern society. Some oxide‐based nanomaterials have been found to show promising antimicrobial activities. However, the industrial synthesis of these oxide materials are harmful to environment. Zinc oxide nano‐flakes were prepared using corn silk (Zea mays) extract. The material was characterized by spectral and microscopic techniques. XRD data shows rutile structure and nano‐crystal size of 36.15 nm. SEM indicates morphology consisting of nano size particles with porous structure. EDX confirms presence of Zn and O. UV‐Vis data shows band gap of 3.62 eV. On excitation, PL exhibits a variety of emission bands in visible spectrum. Dielectric properties suggest the dielectric constant has a well‐dispersed real and imaginary portion. The ZnO NFs were subjected to antimicrobial activities (in dark and under white light) against various strains like E. coli, K. pneumonia and S. aureus. The light induced antibacterial activity is slightly higher as compared to that in dark. Best part of this study is that minimum concentration of ZnO can be used in presence of light thereby reducing the toxicity to the environment due to these metal oxides. Based on the observed results, this material could be used as multi‐dimensional functional material in day‐to‐day life.
