AbstractGraphene oxide (GO)‐based membranes have been widely investigated for separation of dyes, salt ions, heavy metal ions, and biomolecules due to their high mechanical strength, single‐layered structure, large surface area, and high affinity. However, due to irregular pore structure, nanochannels, interlayer distance, easy functionalization, swelling effect, and chemical stability under aqueous environment limited their separation efficiency. In this review, different fabrication methods of GO membranes are summarized. The role of functionalization and cross‐linking on membrane's structural properties, separation performance, and practical applications are discussed. Further, the GO‐based membranes (GOMs) for separation and removal of heavy metal ions are discussed in detail. The factors which influence the separation performance are also highlighted. Finally, recommendations and future directions are suggested.

AbstractThis paper presents applications of a new class of fibre optic acoustic emission (FOAE) sensor to monitor the operation of fluidized bed reactors used in polyethylene production. Specifically, the sensor was implemented to detect undesired, abnormal phenomena related to particle agglomeration, wall sheeting, fine overflow, and variations in the superficial gas velocity. The experiments were executed using a fluidized bed cold model setup for polyethylene powders with average particle sizes of 250, 1000, and 2000 μm. The results demonstrated that the presence of agglomerated particles in the fluidized bed reactor increases the kurtosis of the acoustic emission (AE) signal. Furthermore, the overflow of small particles can be detected by mounting the FOAE sensor below the gas distributor plate and monitoring an increase in the root mean square (RMS) of the AE signal. The AE signal RMS increased with the rising superficial gas velocity. Besides, forming a sheet layer on the reactor wall decreased the AE signal RMS. The proposed sensor's main benefits are its simple design, rapid response to abnormal conditions in the fluidized bed reactor, immunity against electromagnetic noise, high‐temperature resistance, and safety in hazardous areas.
Palladium‐Catalyzed Tandem Cyclization Strategy for the Assembly of 3‐Halo‐1,2,5‐triarylpyrroles from N‐Alkylanilines and Haloalkynes
Authors: Fang Songjia , Jiang Huanfeng , Wu Wanqing 
Published: October 2022

Comprehensive SummaryThis report discloses a distinctive palladium‐catalyzed sequential tandem cyclization reaction of two molecular haloalkynes and one molecular N‐alkylanilines, leading to the efficient assembly of various 3‐halo‐1,2,5‐triarylpyrrole derivatives. Two carbon‐carbon triple bonds and one carbon‐halogen bond in two molecular haloalkynes are transformed conveniently in one single step, which may involve the aminoalkynylation of haloalkyne and cyclization of the newly formed enyne intermediate. The high chemo‐ and regioselectivities, good functional group tolerance and late‐stage modification of the halopyrrole products further illustrate the synthetic value of this strategy.
Determining biomarkers for evaluation and diagnosis of hereditary angioedema
Authors: Singh Umesh , Bernstein Jonathan A. 
Published: October 2022

AbstractRationaleKallikrein‐bradykinin‐forming cascade is known to cause hereditary angioedema (HAE) acute angioedema (AE) attacks. Further research of HAE attacks is needed to explain disease heterogeneity, predict treatment response and identify biomarkers for monitoring HAE attacks. Differential expression of the microvascular endothelial cell‐surface receptors for example, g‐C1qR, cytokeratin‐1, and plasminogen‐activator‐urokinase‐receptor (PLAUR) were hypothesized as biomarkers of AE attacks.MethodTo understand HAE attacks, the differentially expressed genes (DEGs) in RNAseq and mi‐RNAseq data of total RNA extracted from skin biopsies of lesional versus non‐lesional skin collected during and between attacks in Type‐1 HAE patients (n = 11; F:M = 8:3) were compared. To understand the HAE variants, DEGs in skin biopsies from HAE with normal C1 inhibitor (n = 5, F:M = 5:0), and non‐HAE (n = 7; F:M = 3:4) patients were compared. Gene‐set enrichment analyses and regulator effects analysis of these DEGs identified biological pathways in HAE attacks and their regulators.ResultsPLAUR gene, encoding urokinase‐type plasminogen activator (u‐PAR), was constitutively over‐expressed in HAE‐Type‐1 versus non‐HAE controls suggestive of overactive u‐PAR‐mediated signaling via binding to Factor‐XII. Baseline PLAUR expression was associated with severe AE (p = 0.05). The 18 significant DEGs investigated between baseline and AE attack samples in Type1‐HAE were enriched in beta1/beta3‐integrin cell surface interactions and IL‐6‐mediated signaling. Regulator effects analysis suggests a role for IL‐1b in HAE flares. AKT2, the mRNA regulated by the differentially‐expressed miR‐184A, was also associated with HAE attacks.ConclusionAngiopoetin‐activated β1‐integrin signaling pathways causing endothelial destabilization, and avid binding of factor XII to u‐PAR are possible novel mechanisms for progression of the endothelial kinin‐bradykinin‐forming cascade in HAE attacks.
Mutual funds and gender equality in portfolio firms: Toward the sustainable development goals
Authors: Martí‐Ballester Carmen‐Pilar 
Published: October 2022

AbstractAbundant research has documented an overall female penalty. To reduce this, stakeholders are pressuring firms worldwide to adopt diversity goals and to implement practices to promote gender diversity. These gender‐related practices could influence corporate financial performance and, consequently, the financial performance of funds investing in them. However, this effect could differ across sectors related to the Sustainable Development Goals (SDGs). In this study, we examine the effect of gender equality criteria on the financial performance of SDG‐related thematic mutual funds in the United States. We also study the financial impact on mutual funds of each of the four dimensions of gender equality components. We use a dataset of 554 US thematic mutual funds and 2140 US conventional mutual funds investing globally or in the United States markets, covering the 2015–2021 period. To this sample, we apply the Fama and French six‐factor model and Student's t‐parametric test for independent samples. Our findings indicate that the gender equality effect on fund financial performance depends on the sector and geographical market in which mutual funds invest.

AbstractIonic liquids (ILs) have attracted intensive research interest due to their outstanding physiochemical properties. However, comprehensive design is necessary for targeted applications and has rarely been conducted. As a result, the industry‐scale application of ILs is still very limited. In this academia–industry collaborative research among the University of Pittsburgh, Virginia Tech. University, and Seagate Technology LLC, we report the design, synthesis, molecular dynamics (MD) simulation, and characterization of a nanometer‐thick IL, which contains abundant fluorinated segments and a hydroxyl endgroup, as the next‐generation nano‐lubricant for hard disk drives (HDDs). The lab‐ and industry‐level testing results indicate that the IL lubricant performs significantly better than the state‐of‐the‐art lubricant, that is, perfluoropolyether (PFPE) that has been utilized for three decades in the HDD industry in two key functions: thermal stability and fly clearance. Meanwhile, the IL lubricant also shows excellent lubricity and durability. The outstanding performance of the IL has been attributed to its unique molecular structure on the solid substrate, which is supported by MD simulation results. Our work establishes the IL as a promising candidate among the next‐generation media lubricants in HDD industry. Meanwhile, the finding obtained here has important implications in many other applications involving nano‐lubricants.

AbstractThe behavioral mechanisms by which predators encounter prey are poorly resolved. In particular, the extent to which predators engage in active search for prey versus incidentally encountering them has not been well studied in many systems and particularly not for neonate prey during the birth pulse. Parturition of many large herbivores occurs during a short and predictable temporal window in which young are highly vulnerable to predation. Our study aims to determine how a suite of carnivores responds to the seasonal pulse of newborn ungulates using contemporaneous global positioning system (GPS) locations of four species of predators and two species of prey. We used step‐selection functions to assess whether coyotes, cougars, black bears, and bobcats encountered parturient adult female ungulates more often than expected by chance in a low‐density population of mule deer and a high‐density population of elk. We then assessed whether the carnivore species that encountered parturient prey more often than expected by chance did so by shifting their habitat use toward areas with a high probability of encountering neonates. None of the four carnivore species encountered GPS‐collared parturient mule deer more often than expected by chance. By contrast, we determined that cougar and male bear movements positioned them in the proximity of GPS‐collared parturient elk more often than expected by chance which may provide evidence of searching behavior. Although both male bears and cougars exhibited behavior consistent with active search for neonates, only male bears used elk parturition habitat in a way that dynamically tracked the phenology of the elk birth pulse suggesting that maximizing encounters with juvenile elk was a motivation when selecting resources. Our results suggest that there is high interspecific and intersexual variability in foraging strategies among large mammalian predators and their prey.

AbstractThe introduction of electron‐donating, bridging guanidinate substituents in diborane(4) compounds allows the synthesis of a variety of new cationic diborane(4) compounds. In this work, strategies for the directed synthesis of cationic di‐ and tetraboron compounds are presented, leading to the synthesis and complete characterization of several new compounds with distinct structural motifs, all exhibiting BIIatoms directly bound to each other. Hence, we report on tetracationic donor‐acceptor cyclophanes with diboron donor linkers and organic π‐acceptor units, on paddlewheel‐type cationic diboranes, and on unsymmetrically‐substituted monocationic diboranes.
Using shapely values to define subgroups of forecasts for combining
Authors: Ding Zhenni , Chen Huayou , Zhou Ligang 
Published: October 2022

AbstractThis paper proposes an algorithm based on the Shapley value method to select a superior subset from a group of multiple individual forecasts. The Shapley value of a forecast in a combination is an indicator that describes the contribution of the forecast to the combination, which is expressed as the function of four factors in this paper: The accuracy of the forecast, the average accuracy of other forecasts in the combination, the average degree of diversity between the forecast and other forecasts in the combination, and the average degree of diversity between any other two forecasts in the combination. Based on the Shapley value method, the order of different forecasts entering the screening process is determined and the selection algorithm is continuously executed until all the redundant forecasts have been removed from the combination. The effectiveness, superiority, and robustness of the proposed algorithm have been verified via three experiments. The results of empirical studies indicate that the combination of individual forecasts from the selected group markedly outperforms the best individual forecast and the combination of all available forecasts.
U.S. Lawsuit Claims Federal Law Can Require Emergency Abortions
Authors: Latham Stephen R. 
Published: October 2022

AbstractIn the wake of the U.S. Supreme Court's overruling of Roe vs. Wade, states are passing very strict antiabortion laws that the Biden administration is arguing violate the federal Emergency Medical Treatment and Active Labor Act (EMTALA) because those state laws do not permit emergency life‐saving abortions that federal law says must be available to patients. The Biden administration has filed suit against Idaho to have portions of its state law invalidated, and Texas has filed suit against the Biden administration, arguing that its interpretation of EMTALA as requiring that abortions be available to patients in some emergency circumstances amounts to an unconstitutional overreach by the federal government. These suits, and others related to them, may redefine health‐related federalism in the United States.

Published: October 2022

AbstractThe carry‐outs of Dufour and Soret, as well as radiation, and chemical response on a non‐Newtonian MHD Williamson nanofluid flow through an inclined extended plane are discussed in this article. Keller‐box analysis is being used to explore the influence of the Williamson factor here on the fluid domain quantitatively. Ordinary differential equations (ODEs) are recovered from boundary flow equations using appropriate similarity transformations. These ODEs are numerically addressed. Graphs and comparisons are used to simulate and study the features of flow characteristics such as velocity, temperature, and concentration of Williamson nanofluids distributions in response to various emerging parameters. The numerical computations show that our results are in reasonable harmony with previous studies. The numerical computations revealed that for the time being, the density of the momentum fluid layers is diminishing for the values of , Le, , M, and increasing for Gc, Gr. The thickness of the thermal boundary layer is decreasing for Sr, Df, Pr, Gc, and Gr. M, , , R, N, and Le are all on the rise. The concentration profile for R, Le, Nb, Nt, Gr, Gc, and N is decreasing, while Pr, Df, Sr, M, , and are increasing.
The parental reflective functioning questionnaire: Infant version in fathers of infants and association with paternal postpartum mental health

Published: October 2022

AbstractThe parents’ capacity to reflect upon the psychological processes in their child, termed parental reflective functioning (PRF) can be impaired by parental mental health problems. The present study aimed to investigate the factor structure of an infant version of the Parental Reflective Functioning Questionnaire (PRFQ‐I) in a low‐risk sample of 259 Danish fathers of 1–11‐month‐old infants to investigate measurement invariance of the PRFQ‐I between fathers and mothers; and to examine the association between PRF and paternal depressive symptoms, psychological distress, and parenting stress. Confirmatory factor analysis supported a three‐factor model of the PRFQ‐I. Multi‐group factor analysis indicated partial measurement invariance. Multiple linear regressions showed that paternal depressive symptoms were not associated with PRF. There was an interaction effect of paternal depressive symptoms and general psychological distress on paternal interest and curiosity in their infant's mental state and certainty of infant mental state. Increased parenting stress was associated with impaired PRF on all three subscales of the PRFQ‐I. These results provide further evidence for a multidimensional, brief assessment of paternal reflective skills and insight into how variability in paternal psychological functioning relates to impaired PRF in the postpartum period.

AbstractTo evaluate the effects of irrigation regimes and pumice levels on the physiological parameters of rapeseed (Brassica napus) and phenanthrene phytoremediation efficiency, a 15‐week pot experiment was conducted in the open environment of the College of Agriculture at Fasa University. Three irrigation levels, 75%, 100% and 125% of the field capacity, I1, I2 and I3, respectively, and three pumice levels, 0%, 5% and 10% w/w soil, P0, P1 and P2, respectively, were considered. The results showed that the shoot fresh weight, shoot dry weight, shoot‐root ratio, root fresh weight, root dry weight, root volume, root length, root surface area and root length density in the I3P2 treatment increased by 25%, 35%, 22%, 35%, 19%, 24%, 19%, 21% and 19%, respectively, compared to the corresponding control (I2P0). A significant increase in the number of soil microorganisms (32%) and removal of phenanthrene (74%) were achieved in I3P2 compared to I2P0. According to the Pearson correlation coefficient, all physiological parameters of rapeseed had a high negative correlation with the residual phenanthrene in the soil and consequently increased its dissipation. Therefore, the rapeseed plant can be used as a practical and effective species for the phytoremediation of phenanthrene‐contaminated sites.
Ethical HIV research with transgender and non‐binary communities in the United States
Authors: Klein Augustus , Golub Sarit A. 
Published: October 2022

AbstractIntroductionBecause transgender individuals experience disproportionately high rates of HIV infection, this population is an increasing focus of epidemiological and implementation science research to combat the epidemic. However, study participants, providers and other advocates have become increasingly concerned about research practices that may alienate, objectify, exploit or even re‐traumatize the communities they are designed to benefit. This commentary explores the common pitfalls of HIV research with transgender communities and provides a potential framework for ethical, community‐engaged research practice.DiscussionWe review some of the critical challenges to HIV research with transgender and non‐binary communities that limit the potential for such studies to improve practice. For example, scales that measure stigma perceptions/experiences often include activating language, while the consistent focus in research on risk and trauma can often feel judgemental and redundant. Because of limited employment opportunities, some participants may feel undue influence by research stipends; others may perceive their participation as fuelling the larger research economy without providing research jobs to community members. Questions remain regarding optimal strategies for authentic research partnership beyond community advisory boards or focus groups. Transgender and non‐binary researchers are under‐represented and may be tokenized. Many demonstration projects provide much‐needed services that disappear when the research funding is over, and community‐based dissemination efforts are often perceived as “too little, too late” to effect change.ConclusionsBased on this review and input from study participants across the United States, we detail six recommendations for ethical HIV research with transgender and non‐binary communities, including (1) equitable budgeting with community‐based programme partners; (2) representation in the development of both research agenda and methods; (3) integration of research activities into the ongoing work of any clinical or service site, so that individuals’ needs as “clients” can continue to be prioritized over their role as “participants;” (4) mindfully considered compensation that values the contributions of community members, but avoids undue influence; (5) transparent, community‐focused and timely communication at every stage of the study, including research purpose, data usage, preliminary findings and full‐scale results; and (6) planning for sustainability of any programme or services beyond the life of the research project.
