Published: August 2023

AbstractThe rapid development of cold spraying technology for additive manufacturing of engineering components has made it a viable option for developing thick deposits from high-entropy alloys (HEAs). The microstructure of cold-sprayed CoCrFeNiMn deposit was investigated in this study using electron backscattered diffraction, scanning electron microscopy, and finite element analysis (FEA). The limited studies on the impact deformation behavior of the HEA during cold spraying, limiting our understanding of impact phenomena, and interactions between the HEA particles under ultra-high strain rate deformation motivated this study. From the microstructural characterization, heterogeneous microstructure appears to be formed in the cold-sprayed HEA deposit, comprising of equiaxed ultrafine grains at the particle–particle interfacial regions and coarse grains at the particle interiors. The FEA reveals large strain (> 250%) and temperature (> 90% of the alloy solidus temperature), mainly at the splat’s interfaces. Adiabatic shear instability and rotational dynamic recrystallization resulting from heat accumulation and high strain are believed to be responsible for these observations during the ultra-high strain rate deformation of the HEA. The large deformation and grain refinement experienced by the HEA resulted in greater deposit hardness when compared with the sprayed powder, with the nanohardness increasing from 1.16 GPa in the powder to 5.14 GPa in the deposit. This study explores and provides an understanding of the deformation behavior of the HEA and the resulting microstructure during cold spraying.

Abstract
Background
Palliative radiotherapy (PRT) is commonly used to treat symptoms of advanced cancer. PRT has been associated with elevated 30-day mortality (30DM). A Rapid Access Palliative Clinic (RAPC) can streamline the treatment process for patients receiving treatment.

Aims
We reviewed the PRT practices in a radiation oncology network in Ireland, and the implementation of a RAPC. Patient outcomes were assessed to inform future treatment decisions.

Methods
A retrospective review of all patients who received PRT over 6 months in 2018 in St. Luke’s Radiation Oncology Network (SLRON) was undertaken. We assessed 30DM rates, demographics and referral to specialist palliative care (SPC) services. Subsequently, a retrospective analysis was conducted of a RAPC which ran for 6 months from 2019 to 2020. We assessed treatment data and mortality.

Results
Over 6 months, 645 patients commenced PRT in the SLRON. The 30DM for this cohort was 15.8% (n = 102), with most patients having lung primaries. Of the 30DM cohort, only 55% (n = 56) were referred to SPC services and only 26.4% (n = 27) had performance status recorded. Over 6 months, 40 patients attended 28 RAPCs. Of these, 88% (n = 35) received PRT. Single fraction therapy was utilised in 60% and 48% of patients underwent CT simulation and treatment on the same day. Ultimately, 75% of patients received SPC referral.

Conclusions
Referral rates to SPC services and documentation of performance status were low in our 30DM retrospective review cohort. The RAPC facilitated quick treatment turnaround, fewer hospital visits and referral to SPC services.
Strange Fractal Attractors and Optimal Chaos of Memristor–Memcapacitor via Non-local Differentials
Authors: Abro Kashif Ali , Siyal Ambreen , Atangana Abdon 
Published: August 2023

AbstractThe multi-dimensional electronic devices are so called memory circuit elements (memristor or memcapacitor); such memory circuit elements usually rely on previous applied voltage, current, flux or charge based on memory capability with their resistance, capacitance or inductance. In view of above fact, this manuscript investigates the non-integer modeling of memristor–memcapacitor in discrete-time domain through non-singular kernels of fractal fractional differentials and integrals operators. The governing equations of memristor–memcapacitor have been developed for the sake of the dynamical characteristics of simple chaotic circuit. The fractal fractional differentials and integrals operators have been invoked for non-integer modeling of memristor–memcapacitor that can exhibit a combination of dynamical chaotic phenomena. The numerical schemes, numerical simulations, stability analysis and equilibrium points have been highlighted in detail. The comparative chaotic graphs have been discussed in three ways (i) by keeping fractal component fixed and varying fractional component distinctly, (ii) by keeping fractional component fixed and varying fractal component distinctly and (iii) by varying both fractal component and fractional component distinctly. Our results suggest that fractal-fractional model of memristor–memcapacitor retains the memory characteristics.
(Counter-)stereotypical Gendering of Robots in Care: Impact on Needs Satisfaction and Gender Role Concepts in Men and Women Users

Published: August 2023

AbstractWe present a video-based online study (N = 222) examining the impacts of gendering an in-home, socially assistive robot designed to aid with rehabilitative engagement. Specifically, we consider the potential impact on users’ basic psychological need (BPN) fulfillment alongside measures of the robot’s effectiveness as well as the potential impact on human caregiver gender preferences and propensity to gender stereotype more broadly. Our results suggest that the male-gendering of care robots might be particularly beneficial for men, potentially leading to greater BPN fulfillment than female-gendering. Whilst women also showed some similar gender-matching preference (i.e. preferring the female-gendered robot) this effect was less pronounced. Men who saw the male-gendered robot were also significantly more likely to indicate they would prefer a man, or had no gender preference, when asked about human caregiver preferences. Overall, and in line with (some) previous work, we find no evidence of universal positive impact from robot task-gender typicality matching. Together, our results further strengthen existing calls to challenge the default female-gendering of assistive agents seen to date, suggesting that male-gendering might simultaneously boost positive impact for men users whilst challenging stereotypes regarding who can/should do care work.

Published: August 2023

AbstractGuava (Psidium guajava) seeds were used for the preparation of activated carbon (AC) activated using zinc chloride (GCZ36), phosphoric acid (GCH36), potassium hydroxide (GCK36), and one other sample was prepared without activation (GC36), carbonized for 3 h at 600 °C. They were added to cellulose acetate to form hybrid membranes (Ms) using the phase inversion technique. The prepared AC was characterized by % ash content, % weight loss on drying, nitrogen adsorption isotherm, TEM, and XRD. FTIR and SEM were used for the ACs and Ms. GCK36 sample exhibited a higher surface area (905.27 m2/g) and total pore volume (0.5360 mL/g). The hybrid membranes were used to remove malachite green dye (MG) from wastewater. The effect of initial dye concentration, adsorbent dosage, pH, and contact time were studied. Pseudo-first-, pseudo-second-order, and intraparticle diffusion rate equations were proposed and the kinetic data were analyzed. Maximum adsorption capacity (31.82 mg/g) was achieved after 100 min, at pH 6 and 0.25% AC. The adsorption capacity of the cellulose acetate membrane was increased by 111.7% using the prepared activated carbon. The results indicated the chemisorption process and the adsorption was fitted to Langmuir > Freundlich > Tempkin due to R2 values.

Hydrometallurgical Routes to Close the Loop of Electric Vehicle (EV) Lithium-Ion Batteries (LIBs) Value Chain: A Review
Authors: Saleem Usman , Joshi Bhaskar , Bandyopadhyay Sulalit 
Published: August 2023

AbstractWith an ever-increasing demand for energy, there is a proportionate increase in energy storage devices, among which batteries hold the key to the energy transition. Globally, batteries constitute the fastest-growing energy storage technology that is playing a key role in the transport sector electrification leading to rising demand for LIBs. However, there is a substantial need for innovation that will help mitigate the environmental effects of the production and use of LIBs—such as energy use, mineral extraction, and chemical processing. The battery value chain can be seen as an exceptional sustainable value creation opportunity wherein sustainability depends in part on the ability to reuse and recycle batteries. A typical LIB battery serves in electric vehicles (EVs) for about 5–10 years and needs to be replaced when they reach ~ 20% capacity loss. At this stage, the fate of the battery follows one of the routes—disposal, reuse/repurpose/remanufacture (3R) or recycle. However, a major obstacle for car and battery manufacturers to invest in second life, or to otherwise take advantage of the reuse market, is that they in many cases do not have control over the batteries. On the other hand, recycling LIBs holds tremendous potential owing to the recirculation of materials i.e., closed-loop recycling needed for battery manufacturing promoting sustainability. This review will enable readers to devise processes that contribute to closing the loop of the EV LIBs value chain from an industrial perspective as well as critically understand the current state and future of battery recycling.

Fliegende Zeichen, verheißungsvolle Stimmen: Vogelboten in mittelalterlicher Literatur
Authors: Klinger Judith , Winst Silke 
Published: August 2023

ZusammenfassungVögel und die Kommunikation mit ihnen sind in mittelalterlichen Kulturen auf vielfältige Weise präsent: in kunstvollen Visualisierungen, in Wissenstraditionen und theologischen Reflexionen ebenso wie in literarischen Überlieferungen. Flug und Gesang verschaffen ihnen in menschlicher Wahrnehmung eine besondere Stellung, deuten sie doch auf außergewöhnliche Potenziale der Kommunikation und der Grenzüberschreitung hin. Nicht zuletzt legen sie eine Positionierung von Vögeln zwischen irdischer und himmlischer Sphäre nahe. Die Sprechbegabung einzelner Vogelarten trägt dazu bei, dass Vögel häufiger als andere Spezies sprechend oder singend Botschaften, Offenbarungen oder Prophezeiungen übermitteln. Den Begegnungen und Kommunikationsformen zwischen Vögeln und Menschen in der mittelalterlichen Kultur und Literatur sowie den sie begleitenden Mehrdeutigkeiten und Unwägbarkeiten geht dieser Beitrag nach und konzentriert sich dabei auf die Figuration von Vögeln als Boten.

Identifying and Validating Indices of Happiness and Unhappiness in Autistic Children and Examining Them as Quality of Life Indicators During Presession Pairing
Authors: Agarwal Tuhina , Ramey Devon 
Published: August 2023

Abstract
Objectives
Happiness is paramount to an improved quality of life (QoL), but there are barriers to assessing the happiness and overall QoL of autistic children using traditional measures. To address this, Study 1 aimed to identify and validate the idiosyncratic mood indices of three autistic children. In Study 2, these indices were measured as QoL indicators during discrete trial teaching (DTT) sessions that followed presession pairing. Task engagement was recorded as a secondary measure.

Methods
Three preschool boys on the autism spectrum participated in both studies. Their individualized indices of happiness and unhappiness were first identified and validated using an abbreviated procedure that extended previous research. The effects of presession pairing were then examined using a concurrent multiple baseline design across participants. The idiosyncratic mood indices were measured using 10-s partial interval recording, while task engagement was measured using 15-s whole interval recording.

Results
Study 1 demonstrated that the abbreviated procedure was efficient for identifying and validating the idiosyncratic mood indices of the participants. Study 2 found that presession pairing improved the mood of all three children during DTT, but there were minimal increases in task engagement. Percentage of nonoverlapping data (PND) scores initially revealed no effects for indices of happiness (M = 43.2%), large effects for indices of unhappiness (M = 76.4%), and no effects for task engagement (M = 37.6%). Contrary to this, omnibus Tau-U scores suggested large effects for indices of happiness (Tau-U = 0.7), very large effects for indices of unhappiness (Tau-U = 0.9), and moderate effects for task engagement (Tau-U = 0.5).

Conclusions
Individualized indices of happiness and unhappiness can and should be used as QoL indicators during behavioral interventions for autistic children.
Optimising the use of SARC-F for the identification of muscle weakness by considering alternative cut-points: findings from the Newcastle SarcScreen project
Authors: Osman Mo , Witham Miles D. , Sayer Avan A. , Cooper Rachel 
Published: August 2023

Abstract
Purpose
We assessed the impact of applying different SARC-F cut-points for the identification of muscle weakness in an older clinical population.

Methods
We included 159 men and 311 women aged 56–98 years who had completed the SARC-F questionnaire and had their maximum grip strength measured at an Older People’s Medicine Day Unit. We applied cut-points of ≥ 4, 3 and 2 to SARC-F and tested agreement with muscle weakness (grip strength < 27kg men, < 16kg women) in analyses stratified by sex and obesity status.

Results
Prevalence of muscle weakness was 86.8% and 82.6% in men and women, respectively. Sensitivity of the SARC-F increased at lower cut-points (e.g. 81% for ≥ 4 vs 97% for ≥ 2 in women). There was typically greater sensitivity among women than men and among those classified as obese vs non-obese.

Conclusions
These findings suggest that different cut-points may be required to optimise the utility of SARC-F for identifying muscle weakness in different patient sub-groups.
A Bayesian Approach with Prior Mixed Strategy Nash Equilibrium for Vehicle Intention Prediction
Authors: Lucente Giovanni , Dariani Reza , Schindler Julian , Ortgiese Michael 
Published: August 2023

AbstractThe state-of-the-art technology in the field of vehicle automation will lead to a mixed traffic environment in the coming years, where connected and automated vehicles have to interact with human-driven vehicles. In this context, it is necessary to have intention prediction models with the capability of forecasting how the traffic scenario is going to evolve with respect to the physical state of vehicles, the possible maneuvers and the interactions between traffic participants within the seconds to come. This article presents a Bayesian approach for vehicle intention forecasting, utilizing a game-theoretic framework in the form of a Mixed Strategy Nash Equilibrium (MSNE) as a prior estimate to model the reciprocal influence between traffic participants. The likelihood is then computed based on the Kullback-Leibler divergence. The game is modeled as a static nonzero-sum polymatrix game with individual preferences, a well known strategic game. Finding the MSNE for these games is in the PPAD $$\cap$$
∩
PLS complexity class, with polynomial-time tractability. The approach shows good results in simulations in the long term horizon (10s), with its computational complexity allowing for online applications.
Fretting wear behaviour in 6061-T6 aluminium alloy
Authors: Erturun V. , Odabas D. 
Published: August 2023

AbstractIn this study, fretting wear in riveted lap joints of aluminium alloy plates was investigated. For the fretting test, 6061-T6 aluminium alloy plates, which are widely used in aircraft construction, and blind rivets were used. Experiments were carried out using a computer controlled Instron testing machine. Fretting surface roughness, microhardness was investigated by metallographic techniques and scanning electron microscopy.Tensile load cycles in the riveted lap joint were found to cause damage to all surfaces. Two contact surfaces where friction occurs were investigated. The contact surface of the lower plate with the upper plate, and the contact surface of the lower plate with the rivet head. As load and cycles increased, fretting scars and surface roughness increased.Consequently, it has been determined that fretting damages occur between the contact surface of the plates and between the plate and the rivet contact surface.
How does the Appraisal Right with the Concept of the Fair Value Including Synergies Work?: Lessons from Japan
Authors: Iida Hidefusa 
Published: August 2023

AbstractThis article presents how the appraisal right, with the concept of the fair value which includes synergies, has worked in Japanese corporate law. The appraisal right gives dissenting shareholders the ability to protect their interests. The Delaware courts calculate a fair value by excluding synergy effects in appraisal proceedings. One can criticise the exclusion of synergies because the petitioners of the appraisal right might receive less than the merger price. It would be interesting to analyse how the situation changes if the fair value includes synergies. Japanese corporate law gives a good illustration for this. The revision of the Companies Act of Japan in 2005 enhanced the role of the appraisal right by empowering the Court to include synergy value into the determination of fair value. However, Japan's Court developed the doctrine to use the deal price as a fair value with a relatively lax review of the fairness of the deal process. This has resulted in an unattractive situation for petitioners of appraisal remedies, because they rarely gain profits through the appraisal remedy. Empowering minorities in black letter law does not necessarily strengthen minority protection in reality.
The Impact of Cognitive Restructuring on Post-Event Rumination and Its Situational Effect on Socially Anxious Adolescents
Authors: Yu Meng , Zhu Yawen , Gao Dingguo , Xu Qian , Wang Ye , Wang Jianping 
Published: August 2023

AbstractPost-event rumination (PER) has been seen as a key element in the persistence of social anxiety (disorder). Studies on PER-targeted intervention, e.g., cognitive restructuring (CR), has, however, received little attention in adults, not yet in youth. In addition, previous research showed that, compared to interaction, participants reported higher levels of PER after speech task. The main aim of the present study was to investigate the effect of CR targeting PER among socially anxious (Chinese) adolescents and also to compare the intervention effect between speech and interaction situations. The present study recruited a sample of 73 high socially anxious adolescents aged 12–16 years and then randomly assigned them into speech (n = 37) or interaction (n = 36) group, without control group. PER and social anxiety (SA) were measured before and after CR. Analysis of Covariance (ANCOVA) results showed that adolescents’ PER and SA symptoms were significantly improved with intervention with moderate to high effect size. Furthermore, the decrease in PER could significantly predict the improvement of SA. However, the intervention effect showed no difference between groups. Although no control group was included, one-session CR still showed its potential to improve participants’ PER and SA. Limitations and future directions were discussed.
