Published: December 2022

As a critical role in battery systems, polymer binders have been shown to efficiently suppress the lithium polysulfide shuttling and accommodate volume changes in recent years. However, preparation processes and safety, as the key criterions for Li‐S batteries' practical applications, still attract less attention. Herein, an aqueous multifunction binder (named PEI‐TIC) is prepared via an easy and fast epoxy‐amine ring‐opening reaction (10 min), which can not only give the sulfur cathode a stable mechanical property, a strong chemical adsorption and catalytic conversion ability, but also a fire safety improvement. The Li‐S batteries based on the PEI‐TIC binder display a high discharge capacity (1297.8 mAh g−1), superior rate performance (823.0 mAh g−1 at 2 C), and an ultralow capacity decay rate of 0.035% over more than 800 cycles. Even under 7.1 mg cm−2 S‐loaded, the PEI‐TIC electrode can also achieve a high areal capacity of 7.2 mA h g−1 and excellent cycling stability, confirming its application potential. Moreover, it is also noted that TG‐FTIR test is performed for the first time to explore the flame‐retardant mechanism of polymer binders. This work provides an economically and environmentally friendly binder for the practical application and inspires the exploration of the flame‐retardant mechanism of all electrode components.

Published: December 2022

AbstractA hybrid structure constructed by replacing external steel beams and columns in the steel frame (SF) to precast concrete shear walls with insulation (PCSWs) and precast concrete cladding panels (PCCPs, SFPCSW) is proposed in this paper to avoid the problem of columns protruding from walls and PCCPs directly connected with SF. Numerical models of the SF and SFPCSW structures are established in ETABS software based on an 18‐story assembled steel residential building to investigate the seismic performance and collapse resistance capacity of SFPCSW. Time history analysis results show that the SFPCSW exhibits bending‐shearing lateral deformation and has more uniform interstory drift ratios than the SF. Under major earthquakes (i.e., probability of exceedance of 2% in 50 years), the damage of SF is concentrated in stories 1–6; for SFPCSW, the plastic hinges mainly appear in the concrete beams between PCSWs at each story, and the damage in PCSWs and the internal frame is small. Using pinned connections between the steel beam and PCSW reduces the structural lateral stiffness and increases the earthquake load carried by the internal frame. The incremental dynamic analysis results show that the SF and SFPCSW have similar collapse resistance capacities.

AbstractThis article is part of the Dendritic Cell Guidelines article series, which provides a collection of state‐of‐the‐art protocols for the preparation, phenotype analysis by flow cytometry, generation, fluorescence microscopy, and functional characterization of mouse and human dendritic cells (DC) from lymphoid organs and various non‐lymphoid tissues. Within this article, detailed protocols are presented that allow for the generation of single cell suspensions from human lymphohematopoietic tissues including blood, spleen, thymus, and tonsils with a focus on the subsequent analysis of DC via flow cytometry, as well as flow cytometric cell sorting of primary human DC. Further, prepared single cell suspensions as well as cell sorter‐purified DC can be subjected to other applications including cellular enrichment procedures, RNA sequencing, functional assays, and many more. While all protocols were written by experienced scientists who routinely use them in their work, this article was also peer‐reviewed by leading experts and approved by all co‐authors, making it an essential resource for basic and clinical DC immunologists.

Published: December 2022

AbstractAgarases are enzymes that degrade agar and agarose to produce agar oligosaccharides with multiple functional activities. Compared with β‐agarases, the natural source of α‐agarases is limited, which severely restricts the industrial application of α‐agarases. Here, we cloned and heterologously expressed an α‐agarase belonging to glycoside hydrolase family 96 named Cm‐AGA from the marine bacterium Catenovulum maritimum STB14. The production conditions of recombinant Cm‐AGA were optimized as: taking Terrific Broth (TB) (pH 6.5) with 5 g/L of fructose and 24 g/L of yeast extract H07014 as the fermentation medium, after culturing at 37°C for 2 h, isopropyl‐β‐
d‐thiogalactoside was added with a final concentration of 0.01 mM to induce for 44 h. The obtained enzyme activity was 13.81 U/ml and was about 6.6 times the initial activity. The specific activity of recombinant Cm‐AGA was 206.1 U/mg, the optimum temperature and pH were 35°C and 8.0, respectively, and the enzyme activity could be activated by Mn2+ and Ca2+. The hydrolysis product results showed that Cm‐AGA is the first reported α‐agarase with agarobiose (A2) and agarotetraose (A4) as the dominant products, suggesting the great potential of Cm‐AGA in the efficient production of agaro‐oligosaccharides with a low degree of polymerization.

Published: December 2022

AbstractGuanidinoacetic acid (GAA, also known as glycocyamine or guanidinoacetate) is a naturally occurring alpha amino acid derivative and newly recognized dietary compound obtainable by different foods and nutritional supplements. Anecdotal evidence suggests that the GAA exposure from supplements might be a major source of GAA supply, out‐competing other food sources for several orders of magnitude. This original technical paper summarizes information about GAA levels in different nutritional supplements, as derived from the U.S. National Institutes of Health dietary supplement database.

AbstractBackgroundThe study aims to clarify the association of sarcopenia with perioperative and postoperative complications in oral cavity squamous cell carcinoma (OCSCC) patients undergoing curative surgery and to understand the reasons causing the poor oncologic outcomes for OCSCC.MethodsWe conducted a propensity score matching study to investigate the association of perioperative and postoperative outcomes in OCSCC patients with sarcopenia and without sarcopenia. A retrospective analysis of a large national data set from the Taiwan Cancer Registry Database was conducted. At least two claims for patients with a principal diagnosis of sarcopenia within the 12‐month preoperative period were defined as the criteria for sarcopenia diagnosis (ICD‐10‐CM code M62.84). Sarcopenia was diagnosed through the measurement of low muscle strength and low muscle mass by any one of the patient's attending orthopaedic physician, rehabilitation physician, family medicine specialist or geriatrician. A multivariate logistic regression model was used to calculate the perioperative, and postoperative major complications.ResultsOur final cohort included 16 293 patients with OCSCC (10 862 and 5 431 in the sarcopenia and nonsarcopenia groups, respectively) who were eligible for further analysis. The sarcopenia group was 10.40% female and 89.60% male, and the nonsarcopenia group was 9.74% female and 90.26% male. The mean age ± standard deviation (SD) were 56.44 ± 11.14 and 56.22 ± 11.29 for sarcopenia and nonsarcopenia groups. OCSCC patients with sarcopenia undergoing curative surgery had a significantly higher blood transfusion rate and volume; longer intensive care unit (ICU) stay, and hospital stay; higher postoperative 30‐day mortality (adjusted odds ratio [aOR]: 1.12, 95% confidence interval [CI] [1.07, 1.56]) and rates of pneumonia (aOR: 1.34, 95% CI [1.20, 1.50]), acute renal failure (aOR: 1.45, 95% CI [1.12, 1.87]) and septicaemia (aOR: 1.29, 95% CI [1.15, 1.45]); higher postoperative first‐year mortality (aOR: 1.18, 95% CI [1.13, 1.51]) and rates of pneumonia (aOR: 1.43, 95% CI [1.30, 1.56]), acute myocardial infarction (aOR: 1.52, 95% CI [1.06, 2.18]) and septicaemia (aOR: 1.29, 95% CI [1.15, 1.45]).ConclusionsOCSCC patients with sarcopenia might exhibit more perioperative and surgical complications than those without sarcopenia.

AbstractIntroductionRandomized trials and observational studies have consistently reported rates of sustained virological response (SVR), equivalent to hepatitis C virus (HCV) cure, as high as 95% following treatment with direct‐acting antiviral (DAA) treatment in individuals with HIV and HCV co‐infection. However, large studies assessing whether SVR rates differ according to demographic and clinical strata are lacking. Additionally, the SVR rates reported in the literature were typically computed in non‐random samples of individuals with available post‐DAA HCV‐RNA measures. Here, we aimed to estimate the probability of SVR after DAA treatment initiation in persons with HIV and HCV co‐infection overall and by demographic and clinical characteristics with and without adjustment for missing HCV‐RNA testing.MethodsWe included adults with HIV‐HCV co‐infection who received DAA treatment between 2014 and 2020 in HepCAUSAL, an international collaboration of cohorts from Europe and North America. We estimated the proportions of DAA recipients who had documented SVR (defined as an undetectable HCV‐RNA at least 12 weeks after the end of DAA treatment) overall and by strata defined by age, sex, presence of cirrhosis, calendar period, mode of HIV acquisition, CD4 cell count and HCV genotype at DAA treatment. We then compared these rates with those obtained using the parametric g‐formula to impute SVR status for individuals with no SVR assessment.Results and DiscussionA total of 4527 individuals who initiated DAA treatment (88% males, median [IQR] age 56 [50, 62] years) were included. Of the total of 642 (14%) individuals had no HCV‐RNA test on or after 12 weeks after the end of treatment. The overall observed and g‐formula imputed SVR rates were 93% (95% CI 93, 94) and 94% (95% CI 92, 95), respectively. SVR estimates were similarly high across all strata. A substantial proportion of individuals who received DAA treatment were never assessed for SVR post‐DAA and strategies for more systematic routine HCV‐RNA testing should be considered.ConclusionsOur estimates with and without adjustment for missing HCV‐RNA testing indicate SVR rates of approximately 95%, like those reported in clinical trials.
Internet‐based family training with telephone coaching to promote mental health treatment initiation among veterans with posttraumatic stress disorder: A pilot study

Published: December 2022

ABSTRACTPosttraumatic stress disorder (PTSD) is common among military veterans, yet many affected veterans do not seek treatment. Family members of these veterans often experience compromised well‐being and a desire for the veteran to receive mental health care. The Veterans Affairs (VA)–Community Reinforcement and Family Training (VA‐CRAFT) for PTSD is an internet‐based intervention intended to teach veterans’ family members skills to encourage veterans to initiate mental health care. This study assessed the feasibility, acceptability, and potential efficacy of VA‐CRAFT with telephone coaching in a sample of 12 spouses and intimate partners of veterans with PTSD. Participants completed the intervention over 12 weeks and were assessed pre‐ and posttreatment. For feasibility, 75.0% (n = 9) of participants completed the intervention and reported few difficulties and ease of use. Supporting acceptability, all nine completers had mostly favorable impressions of the intervention and perceived it as helpful. Finally, six (50.0%) participants got the PTSD‐affected veteran to engage in mental health care; however, aside from potentially increasing treatment talk frequency, outcome expectancy, and self‐efficacy, ds = 0.60–1.08, no apparent improvements were observed for any well‐being outcomes, ds = 0.01–0.40. Although the findings are promising, given the study limitations, future research is required to evaluate this approach in a full‐scale randomized controlled trial.

Published: December 2022

AbstractNowadays, hydrogels‐based microneedles (MNs) have attracted a great interest owing to their outstanding qualities for biomedical applications. For the fabrication of hydrogels‐based microneedles as tissue engineering scaffolds and drug delivery carriers, various biomaterials have been tested. They are required to feature tunable physiochemical properties, biodegradability, biocompatibility, nonimmunogenicity, high drug loading capacity, and sustained drug release. Among biomaterials, human proteins are the most ideal biomaterials for fabrication of hydrogels‐based MNs; however, they are mechanically weak and poorly processible. To the best of the knowledge, there are no reports of xeno‐free human protein‐based MNs so far. Here, human albumin‐based hydrogels and microneedles for tissue engineering and drug delivery by using relatively new processible human serum albumin methacryloyl (HSAMA) are engineered. The resultant HSAMA hydrogels display tunable mechanical properties, biodegradability, and good biocompatibility. Moreover, the xeno‐free HSAMA microneedles display a sustained drug release profile and significant mechanical strength to penetrate the model skin. In vitro, they also show good biocompatibility and anticancer efficacy. Sustainable processible human albumin‐based biomaterials may be employed as a xeno‐free platform in vivo for tissue engineering and drug delivery in clinical trials in the future.

AbstractThis study investigates the corrosion of Hastelloy‐N and Hastelloy‐G35 alloys in an environment of vapors generated from FLiNaK (LiF–NaF–KF: 46.5–11.5–42.0 mol%) salt in an argon and partial (5%) oxygen at 800°C for 48 h. The result of the experiment showed that Hastelloy‐N and Hastelloy‐G35 experienced corrosion in the salt vapor/oxygen environment, causing an increase in the final weight of the samples. The corroded layer had fluorides and oxygen‐bearing compounds in the Hastelloy‐N samples, and oxide‐containing compounds in the Hastelloy‐G35 samples. The elemental mappings of the surface area, of a line across the surface (line scan) and of a cross‐section of the Hastelloy‐N samples showed Mo‐deficient areas and Mo‐rich areas, which reacted differently with the corrosive environment in the case of Hastelloy‐N samples. On the other hand, the elemental mappings of Hastelloy‐G35 samples showed a significant amount of chromium and iron oxides, as chromium had diffused out to the surface and reacted preferentially with oxygen (rather than fluoride) to form part of the corroded layer.
Performance dependency of LSTM and NAR beamformers with respect to sensor array properties in millimeter‐wave V2I scenario
Authors: Kumar Ravi , Singh Hardeep 
Published: December 2022

AbstractInterference prediction is a challenging problem in millimeter‐wave V2I scenarios. The implementation of a practical V2I network is limited because of the interference due to the random nature of the wireless channel. This paper proposes an adaptive beamforming technique for mitigation of interference in V2I networks. In this work, long short‐term memory (LSTM) and nonlinear autoregressive (NAR)‐based regressors have been employed to predict the angles between the RSU and UE. Advance prediction of transmit and receive signals enables reliable V2I communication. Instead of predicting the beamforming matrix directly, we predict the main features using LSTM for learning dependencies in the input time series where complex variables were taken as input states and the final beamformed signal was the output. Simulation results have confirmed that the proposed LSTM model achieves comparable performance in terms of system throughput compared to the NAR method implemented as an artificial neural network.

AbstractIn this article, a superstrate and arrow‐shaped frequency selective surfaces (FSSs) embedded twist aperture array has been presented. In this article, a single arrow‐shaped FSS is kept in the E‐plane and the superstrate is kept above the aperture to form a circularly polarized twist waveguide array. Optimization and analysis have been carried out by commercially available software Ansys HFSS 15.0. The presented waveguide array has an input reflection coefficient ranging from 8.6 to 9.62 GHz and an axial ratio ranging from 8.7 to 9.37 GHz. Additionally, the presented array provides higher gain as compared to the conventional open‐ended WR‐90 twist waveguide.
A low‐profile dual‐polarized heterogeneous MIMO antenna arrays with uniform beamwidth
Authors: Zhou Xing , He Dongling , Chen Yikai 
Published: December 2022

AbstractIn this work, a heterogeneous 6 × 4 dual‐polarized MIMO antenna array was developed to achieve antenna elements with uniform 10 dB‐beamwidth (120° ± 10°). To constrain the 10 dB‐beamwidth, two types of antenna elements are designed and properly placed in the antenna array according to the nonuniform electromagnetic coupling environment. A nonuniform aperiodic metasurface with equivalent capacitance loading effect is then proposed to compensate the inductance of the heterogeneous antenna array. It results in a low‐profile height of 0.17λL and good impedance matching over 40% bandwidth. The unit cells in the metasurface are arranged with non‐uniform spacing to achieve uniform 10 dB‐beamwidth of the antenna elements in an antenna array environment. Both simulation and measurement results validate that the proposed design achieves stable radiation patterns and uniform 10 dB‐beamwidth (120° ± 10°) over a wide frequency band of 1.8–2.7 GHz. Because of these attractive features, the proposed antenna array becomes a promising candidate for massive multiple‐input and multiple‐output base station antennas.
Maximum weight perfect matching problem with additional disjunctive conflict constraints
Authors: Akyüz M. Hakan , Altınel İ. Kuban , Öncan Temel 
Published: December 2022

AbstractWe focus on an extension of the maximum weight perfect matching problem with additional disjunctive conflict constraints in conjunction with the degree and binary restrictions. Given a simple graph with a nonnegative weight associated with each edge and a set of conflicting edges, the perfect matching problem with conflict constraints consists of finding a maximum weight perfect matching without any conflicting edge pair. Unlike the well‐known ordinary maximum weight perfect matching problem this one is strongly ‐hard. We propose two branch‐and‐bound algorithms for the exact solution of the problem. The first one is based on an equivalent maximum weight stable set formulation with an additional cardinality restriction obtained on the graph representing conflict relations and uses the information coming from its maximal stable sets. The second one is essentially a recursive depth first search scheme that benefits from simple upper bounds incorporated with a fast infeasibility detection procedure to prune the branch‐and‐bound tree. According to the extensive computational tests it is possible to say that they are both very efficient.
