Published: September 2023

AbstractPolydopamine (PDA) has been widely used in the field of energetic materials; however, there are few reports on the ammonium perchlorate (AP) coating of PDA. In this article, to improve the mechanical properties of the GAP‐ETPE‐based propellant, a two‐step method was used to coat the AP with PDA and used in glycidyl azide polymer (GAP) based propellant. SEM, EDS, XRD, and XPS were used to analyze the morphology and composition of PDA@AP, while contact angle testing and calculation were performed to measure the wettability and surface energy of both PDA@AP and GAP‐ETPE. In addition, the tensile strength and elongation of the propellant were measured. The results showed that the PDA@AP composite particles were successfully prepared. The crystal form remained unchanged during the preparation process. The wettability of PDA on AP was improved through the coating of PDA, leading to an increase in the surface energy of AP and enhancing the adhesion between AP and GAP. Mechanical performance testing shows that using PDA@AP in propellants increased the tensile strength of the propellant from 1.2 to 1.8 MPa, while the elongation at break decreased from 208% to 155%. The “dewetting ratio” has also decreased from 2.88 to below 2.5.
Body painting, ultrasound, clinical examination, and peer‐teaching: A student‐centered approach to enhance musculoskeletal anatomy learning
Authors: Bilella Alessandro , Eppler Elisabeth , Link Karl , Filgueira Luis 
Published: September 2023

AbstractThe presented course, established 2016 as a compulsory elective for 22nd‐year bachelor medical students, aimed to enhance deep learning of upper and lower limb anatomy from a clinical perspective by a maximum of student‐centered activities combining hands‐on skills training with team‐learning. Three cohorts (in total 60 students) participated in this study. Students rotated through body painting, ultrasound, and clinical investigation supervised by faculty or an experienced clinician. Teams of 3‐4 students prepared presentations on clinical anatomy and pathological conditions, which by teacher‐ and peer assessments on average achieved >85% (mean 17.8/20 points ± 1.06). After each activity session, the students reported their learning experience through a reflective diary. Fifty students (83%) evaluated the course by a voluntary anonymous questionnaire combining Likert‐type scale and free‐text questions to assess, predominantly, perception of course activities and their perceived influence on learning anatomy. Journal reports and questionnaires revealed that the students highly valued the course, and 92% (29 females, 17 males) rated group work satisfying or well‐perceived. The highest appreciation achieved ultrasound followed by clinical examination and body painting, which one third proposed to integrate into the regular dissection course. All students recommended the course to their younger peers. This course was feasible to integrate in the pre‐existing curriculum. Limiting factors to offer this elective course to more students are availability of clinical teachers, technical equipment, and education rooms. Being student‐directed tasks, body painting and reflective diary‐writing would be feasible to implement without additional faculty, which we recommend to educators for student engagement activation.
Triphenylamine‐Based N,O‐Bidentate BF2‐Enolimine Initiator for Three‐Arm Star Polymethacrylates with Dual‐State Fluorescent Emission
Authors: Yang Dong , Tian Guangming , Ma Jianhua 
Published: September 2023

AbstractThree‐arm star polymethacrylates with dual‐phase (solution and solid‐state) fluorescent emission have been synthesized via atom transfer radical polymerization (ATRP) using a triphenylamine‐derived organboron complex (TAPA‐BKI‐3Br) as initiator. The as‐synthesized three‐arm star polymethacrylates exhibited bright emission in both solution and the solid states due to the highly twisted structure and intramolecular charge transfer (ICT) effect of TAPA‐BKI core, as well as the steric effect and restriction of intramolecular motions from the polymer arms. And the polymer chains have an important influence on the photophysical behavior of the as‐synthesized three‐arm star polymethacrylates in the aggregated state.
Data‐driven policy iteration algorithm for continuous‐time stochastic linear‐quadratic optimal control problems
Authors: Zhang Heng , Li Na 
Published: September 2023

AbstractThis paper studies a continuous‐time stochastic linear‐quadratic (SLQ) optimal control problem on infinite‐horizon. Combining the Kronecker product theory with an existing policy iteration algorithm, a data‐driven policy iteration algorithm is proposed to solve the problem. In contrast to most existing methods that need all information of system coefficients, the proposed algorithm eliminates the requirement of three system matrices by utilizing data of a stochastic system. More specifically, this algorithm uses the collected data to iteratively approximate the optimal control and a solution of the stochastic algebraic Riccati equation (SARE) corresponding to the SLQ optimal control problem. The convergence analysis of the obtained algorithm is given rigorously, and a simulation example is provided to illustrate the effectiveness and applicability of the algorithm.

Authors: Larhrissi Rachid , Benoudi Mustapha 
Published: September 2023

AbstractThe primary objective of this research is to generalize the concept of controllability with constraints to cases where the output function is a Riemann–Liouville fractional derivative of order More precisely, if , we obtain the enlarged controllability of the system state and enlarged controllability of the gradient state of the system is obtained with Moreover, we aim to characterize the optimal control that enables us to guide a linear parabolic system to a fractional final state within the evolution system's domain. We adopt two approaches to solve the aforementioned problem: The first is based on the Lagrangian technique, and the second one employs the subdifferential theory. Subsequently, we develop an algorithm to compute the minimum energy control. Finally, we provide numerical simulations to illustrate the validity of the obtained theoretical results.
Creating a reference range of common problem behaviors and replacement behaviors in neurotypical children
Authors: VanDevander Jessica , Warner Allison , Kazemi Ellie , Fahmie Tara 
Published: September 2023

AbstractThere are limited resources outlining age‐referenced rates of problem behavior displayed by neurotypical children. Such information is important for practitioners as a basis for social comparison when they are targeting behavior reduction goals for neurodivergent clients. We distributed a survey to parents of children aged 1–10 years without a developmental diagnosis in which parents reported frequency of five problem behaviors across a 24‐h period, as well as commonly targeted replacement behaviors. Problem behavior was reported across all age groups to varying degrees based on topography and age. Replacement behaviors, such as waiting and tolerating denials generally improved as children increased in age but still largely remained below 80% of opportunities. The present study may serve as a reference for researchers and clinicians to set goals that are developmentally appropriate.

Published: September 2023

AbstractThe electrochemical reduction of carbon dioxide offers a sound and economically viable technology for the electrification and decarbonization of the chemical and fuel industries. In this technology, an electrocatalytic material and renewable energy‐generated electricity drive the conversion of carbon dioxide into high‐value chemicals and carbon‐neutral fuels. Over the past few years, single‐atom catalysts have been intensively studied as they could provide near‐unity atom utilization and unique catalytic performance. Single‐atom catalysts have become one of the state‐of‐the‐art catalyst materials for the electrochemical reduction of carbon dioxide into carbon monoxide. However, it remains a challenge for single‐atom catalysts to facilitate the efficient conversion of carbon dioxide into products beyond carbon monoxide. In this review, we summarize and present important findings and critical insights from studies on the electrochemical carbon dioxide reduction reaction into hydrocarbons and oxygenates using single‐atom catalysts. It is hoped that this review gives a thorough recapitulation and analysis of the science behind the catalysis of carbon dioxide into more reduced products through single‐atom catalysts so that it can be a guide for future research and development on catalysts with industry‐ready performance for the electrochemical reduction of carbon dioxide into high‐value chemicals and carbon‐neutral fuels.

Published: September 2023

AbstractA multi‐model predictive control strategy based on kernel fuzzy c‐means (KFCM) clustering and integrated model is proposed for the complex problem of rapid and accurate control of ammonia injection in selective catalytic reduction (SCR) denitrification systems of coal‐fired power plants under a wide range of variable load conditions. First, the SCR data samples are clustered using the KFCM clustering algorithm, and the number of clusters is determined by introducing the Xie‐Beni index. Second, the prediction model of the SCR denitrification system is established by an integrated modelling approach, and the sub‐learners of the integrated model are the genetic algorithm optimized back propagation (GA‐BP) neural network model and the least squares support vector machine (LSSVM) model. Third, a multi‐model prediction controller based on the particle swarm optimization (PSO) algorithm and the integrated model is designed and developed. To ensure the stability of the system, a model‐switching strategy based on the minimum Euclidean distance is proposed. Finally, simulation verification and industrial field application verification are fulfilled by comparing with proportion integral differential (PID) control and single model predictive control (MPC). The results show that the multi‐model predictive control method proposed in this paper can obtain higher control accuracy and better control stability and meet the control requirements for the long‐term operation of the SCR denitrification system.
Palladium‐Catalyzed Oxidative Alkynylation of Allenyl Ketones: Access to 3‐Alkynyl Poly‐substituted Furans†
Authors: Dou Bowen , Wang Kang , Wang Jianbo 
Published: September 2023

Comprehensive SummaryFurans bearing alkynyl substituents are highly useful in organic synthesis. However, the methodologies to access these important furan derivatives are rather limited. We herein report an efficient synthesis of alkynylated furan derivatives based on Pd‐catalyzed oxidative cross‐coupling reaction between allenyl ketones and terminal alkynes. This novel synthesis of alkynylated furans with wide substrate scope is operationally simple and tolerates various functional groups. Mechanistically, the formation of the palladium carbene through cycloisomerization and the subsequent alkynyl migratory insertion are proposed as the key steps in the transformation. The reaction reported in this paper further demonstrates the generality of the carbene‐based cross coupling.
Use of religious and spiritual responses after trauma to prevent posttraumatic stress symptoms and suicidality: The role of meaning in life
Authors: Sinnott Sinead M. , Park Crystal L. , George Jamilah R. , Gnall Katherine E. , David Adam B. 
Published: September 2023

AbstractBackgroundThe present study examined the relationship between religious/spiritual (R/S) responses to trauma, meaning in life, and psychopathology among US veterans (n = 729).MethodsParticipants (66.7% male and 83.2% White) completed study questionnaires assessing positive religious coping, divine spiritual struggle, meaning in life, posttraumatic stress symptoms (PTSS), and suicidality severity. Assessments were conducted via telephone interviews at baseline (T1), 3 months (T2) and 6 months (T3).ResultsDivine spiritual struggle was associated with lower meaning in life, higher suicidality and higher PTSS at all time points. Positive religious coping was associated with higher meaning in life at all time points and lower suicidality at T2. Meaning in life fully mediated relationships between divine spiritual struggle and both PTSS and suicidality. While higher levels of T1 positive religious coping predicted increased T3 PTSS when controlling for T1 PTSS, meaning in life partially mediated this relationship, with a negative indirect effect. Meaning in life also fully mediated the relationship between positive religious coping and later suicidality, with a negative indirect effect.DiscussionThese findings suggest that divine spiritual struggle consistently predicts both higher PTSS and suicidality. Further, a sense of meaning plays a large role in linking R/S responses to trauma and psychological outcomes. It holds promise as a means through which positive religious coping may exert beneficial effects. Clinicians should be particularly mindful of negative R/S responses after trauma as a risk factor for adverse psychological outcomes. Future research should examine whether meaning‐based interventions are beneficial after trauma.

How impact investing funds invest in social‐purpose organizations: A cross‐country comparison
Authors: Borrello Alice , Bengo Irene , Moran Michael 
Published: September 2023

AbstractImpact investing funds (IIFs) are a type of investment fund that aims to achieve both financial and social goals, and they have become a valuable resource for social purpose organizations (SPOs) seeking capital. Our research evaluates the investment process by comparing approaches in two countries, Italy and Australia. We conducted semi‐structured interviews with 9 IIFs and 12 SPOs and used the Gioia Methodology to conduct the data analysis. We found both similar features and divergences. The investing process by IIFs in Australia is conservative, more risk averse and more profit‐oriented with a predominant “finance‐first” strategy. By contrast, in Italy there is a clear preference for “impact‐led” investment. We argue this illustrates a fundamental difference in investment philosophy and that IIFs in the two countries navigate, interpret, and understand the field of impact investment in contrasting ways. Finally, we contribute to the growing literature on impact investing by putting forward an “ideal” impact investment process that respects the integrity and peculiarities of the Social Impact Investment approach.

Published: September 2023

AbstractVanadium redox flow battery (VRFB) electrodes face challenges related to their long‐term operation. We investigated different electrode treatments mimicking the aging processes during operation, including thermal activation, aging, soaking, and storing. Several characterization techniques were used to deepen the understanding of the treatment of carbon felts. Synchrotron X‐ray imaging, electrochemical impedance spectroscopy (EIS) with the distribution of relaxation times analysis, and dynamic vapor sorption (DVS) revealed differences between the wettability of felts. The bulk saturation after electrolyte injection into the carbon felts significantly differed from 8 % to 96 %. DVS revealed differences in the sorption/desorption behavior of carbon felt ranging from a slight change of 0.8 wt % to over 100 wt %. Additionally, the interactions between the water vapor and the sample change from type V to type H2. After treatment, morphology changes were observed by atomic force microscopy and scanning electron microscopy. Cyclic voltammetry and EIS were used to probe the electrochemical performance, revealing different catalytic activities and transport‐related impedances for the treated samples. These investigations are crucial for understanding the effects of treatments on the performance and optimizing materials for long‐term operation.
Diet‐microbiome‐immune interplay in multiple sclerosis: Understanding the impact of phytoestrogen metabolizing gut bacteria
Authors: Lehman Peter C. , Ghimire Sudeep , Price Jeffrey D. , Ramer‐Tait Amanda E. , Mangalam Ashutosh K. 
Published: September 2023

AbstractMultiple sclerosis (MS) is a chronic and progressive autoimmune disease of the central nervous system (CNS), with both genetic and environmental factors contributing to the pathobiology of the disease. Although HLA genes have emerged as the strongest genetic factor linked to MS, consensus on the environmental risk factors is lacking. Recently, the gut microbiota has garnered increasing attention as a potential environmental factor in MS, as mounting evidence suggests that individuals with MS exhibit microbial dysbiosis (changes in the gut microbiome). Thus, there has been a strong emphasis on understanding the role of the gut microbiome in the pathobiology of MS, specifically, factors regulating the gut microbiota and the mechanism(s) through which gut microbes may contribute to MS. Among all factors, diet has emerged to have the strongest influence on the composition and function of gut microbiota. As MS patients lack gut bacteria capable of metabolizing dietary phytoestrogen, we will specifically discuss the role of a phytoestrogen diet and phytoestrogen metabolizing gut bacteria in the pathobiology of MS. A better understanding of these mechanisms will help to harness the enormous potential of the gut microbiota as potential therapeutics to treat MS and other autoimmune diseases.
