Gender comparison of perceptual-cognitive learning in young athletes
Authors: Legault Isabelle , Faubert Jocelyn 
Published: April 2024

AbstractElite athletes demonstrate higher perceptual cognitive abilities compared to non-athletes and those capacities can be trained. A recent study showed that differences were observed between male and female athletes in their cognitive abilities whereby male athletes showed superior perceptual abilities compared to female athletes. The purpose of this study was to investigate whether there were gender differences in athletes’ perceptual cognitive learning using a 3D-MOT tracking task. The study was performed on 72 young people from 16 to 22 years of age; athlete males and females and non-athlete males and females were distributed in four distinct groups. Five sessions comprised of three thresholds were performed with each participant. Results indicated that all participants benefited from training and significantly increased their speed thresholds. Initial scores showed that male athletes achieved higher speed thresholds than any other groups. Furthermore, after 5 weeks, female athletes obtained higher speed thresholds in comparison to their non-athlete counterparts. In conclusion, engaging in sporting activity is associated with improved perceptual-cognitive abilities and learning. The results support the notion that competitive sport-related activity is beneficial for perceptual-cognitive functions and emphasizes the benefits of participating in sport-related activities for improved brain function with an even greater impact for females.

AbstractMeniscal injury represents a common type of knee injury, accounting for over 50% of all knee injuries. The clinical diagnosis and treatment of meniscal injury heavily rely on magnetic resonance imaging (MRI). However, accurately diagnosing the meniscus from a comprehensive knee MRI is challenging due to its limited and weak signal, significantly impeding the precise grading of meniscal injuries. In this study, a visual interpretable fine grading (VIFG) diagnosis model has been developed to facilitate intelligent and quantified grading of meniscal injuries. Leveraging a multilevel transfer learning framework, it extracts comprehensive features and incorporates an attributional attention module to precisely locate the injured positions. Moreover, the attention-enhancing feedback module effectively concentrates on and distinguishes regions with similar grades of injury. The proposed method underwent validation on FastMRI_Knee and Xijing_Knee dataset, achieving mean grading accuracies of 0.8631 and 0.8502, surpassing the state-of-the-art grading methods notably in error-prone Grade 1 and Grade 2 cases. Additionally, the visually interpretable heatmaps generated by VIFG provide accurate depictions of actual or potential meniscus injury areas beyond human visual capability. Building upon this, a novel fine grading criterion was introduced for subtypes of meniscal injury, further classifying Grade 2 into 2a, 2b, and 2c, aligning with the anatomical knowledge of meniscal blood supply. It can provide enhanced injury-specific details, facilitating the development of more precise surgical strategies. The efficacy of this subtype classification was evidenced in 20 arthroscopic cases, underscoring the potential enhancement brought by intelligent-assisted diagnosis and treatment for meniscal injuries.

Published: April 2024

AbstractMolecular metal complex catalysts are highly tunable in terms of their CO2 reduction performance by means of their flexible molecular design. However, metal complex catalysts have challenges in their structural stability and it has not been possible to synthesize high-value-added C3 products due to their inability to perform C–C coupling. Here we show a CO2 reduction reaction catalysed by a Br-bridged dinuclear Cu(I) complex that produces C3H7OH with high robustness during the reaction. The C–C coupling reaction mechanism was analysed by experimental operando surface-enhanced Raman scattering analysis, and theoretical quantum-chemical calculations proposed the formation of a C–C coupling intermediate species with substrate incorporation between the two Cu centres. Molecular design guidelines based on this discovery offer an approach to developing next-generation catalysts that generate multicarbon CO2 reduction products.

Published: April 2024

AbstractIndustrial land drives economic growth but also contributes to global warming through carbon dioxide emissions. Still, the variance in its impact on economies and emissions across countries at different development stages is understudied. Here, we used satellite data and machine learning to map industrial land at 30 m resolution in ten countries with substantial industrial value-added, and analyzed the impact of industrial land expansion on economic growth and emissions in 216 subnational regions from 2000 to 2019. We found that industrial land expansion was the leading factor for economic growth and emissions in developing regions, contributing 31% and 55%, respectively. Conversely, developed regions showed a diminished impact (8% and 3%, respectively), with a shift towards other economic growth drivers like education. Our findings encourage developing regions to consider the adverse effects of climate change during industrial land expansion and that developed regions prioritize human capital investment over further land expansion.
3.7 billion year old detrital sediments in Greenland are consistent with active plate tectonics in the Eoarchean

Published: April 2024

AbstractPlate tectonic processes modulate element cycling, crust generation, and differentiation, yet at what point in Earth’s history these processes emerged remains debated. Here we present evidence that parts of the >3.7 Ga Isua Supracrustal Belt formed within a fore-arc setting, consistent with the operation of plate tectonics in the Eoarchean. We show that the oldest known sequence of detrital meta-sedimentary rocks were deposited conformably above chemical sediments on a volcanic basement. Mineral and trace elemental compositions show that turbiditic and pelagic detrital sediments were derived from terrains, comprising both basalts and differentiated tonalitic igneous rocks. The boninitic volcanic basement would have formed in a tensile environment before the adjacent terrains which sourced the clastic sediments. This suggests formation within a fore-arc during the initial few million years of subduction. This environment may have facilitated the local proliferation of life suggested by the frequent occurrence of layers rich in biogenic graphite.

AbstractSkeletal muscle aging is a key contributor to age-related frailty and sarcopenia with substantial implications for global health. Here we profiled 90,902 single cells and 92,259 single nuclei from 17 donors to map the aging process in the adult human intercostal muscle, identifying cellular changes in each muscle compartment. We found that distinct subsets of muscle stem cells exhibit decreased ribosome biogenesis genes and increased CCL2 expression, causing different aging phenotypes. Our atlas also highlights an expansion of nuclei associated with the neuromuscular junction, which may reflect re-innervation, and outlines how the loss of fast-twitch myofibers is mitigated through regeneration and upregulation of fast-type markers in slow-twitch myofibers with age. Furthermore, we document the function of aging muscle microenvironment in immune cell attraction. Overall, we present a comprehensive human skeletal muscle aging resource (https://www.muscleageingcellatlas.org/) together with an in-house mouse muscle atlas to study common features of muscle aging across species.
Integrating Emotion Perception in Rehabilitation Programs for Cochlear Implant Users: A Call for a More Comprehensive Approach
Authors: Valentin Olivier , Lehmann Alexandre , Nguyen Don , Paquette Sébastien 
Published: April 2024

Purpose:
Postoperative rehabilitation programs for cochlear implant (CI) recipients primarily emphasize enhancing speech perception. However, effective communication in everyday social interactions necessitates consideration of diverse verbal social cues to facilitate language comprehension. Failure to discern emotional expressions may lead to maladjusted social behavior, underscoring the importance of integrating social cues perception into rehabilitation initiatives to enhance CI users' well-being. After conventional rehabilitation, CI users demonstrate varying levels of emotion perception abilities. This disparity notably impacts young CI users, whose emotion perception deficit can extend to social functioning, encompassing coping strategies and social competence, even when relying on nonauditory cues such as facial expressions. Knowing that emotion perception abilities generally decrease with age, acknowledging emotion perception impairments in aging CI users is crucial, especially since a direct correlation between quality-of-life scores and vocal emotion recognition abilities has been observed in adult CI users. After briefly reviewing the scope of CI rehabilitation programs and summarizing the mounting evidence on CI users' emotion perception deficits and their impact, we will present our recommendations for embedding emotional training as part of enriched and standardized evaluation/rehabilitation programs that can improve CI users' social integration and quality of life.

Conclusions:
Evaluating all aspects, including emotion perception, in CI rehabilitation programs is crucial because it ensures a comprehensive approach that enhances speech comprehension and the emotional dimension of communication, potentially improving CI users' social interaction and overall well-being. The development of emotion perception training holds promises for CI users and individuals grappling with various forms of hearing loss and sensory deficits. Ultimately, adopting such a comprehensive approach has the potential to significantly elevate the overall quality of life for a broad spectrum of patients.

Published: April 2024

AbstractIn unmanned aerial vehicle ad‐hoc network (UANET), the node speed of unmanned aerial vehicles (UAVs) may reach up to 400 km/h. The fast or slow movement of UAV nodes leads to different speeds of topology change of the nodes. Traditional optimized link state routing (OLSR) protocol cannot adaptively adjust the routing update period when the network topology changes, which may lead to the nodes calculating incorrect routing tables. This increases the average end‐to‐end delay and packet loss rate for packet transmission. To enhance the adaptability of OLSR routing protocol to network topology changes, this paper proposes a multi‐agent independent deep deterministic policy gradient‐OLSR (MA‐IDDPG‐OLSR) routing protocol based on distributed multi‐agent reinforcement learning. The protocol deploys DDPG algorithm on each UAV node, and each UAV node adaptively adjusts the Hello and TC message sending intervals, according to the one‐hop neighbouring nodes as well as its own state. Simulation results show that the proposed protocol is able to improve the throughput and reduce the packet loss rate as compared to traditional AODV, GRP, OLSR, and distributed multiple‐agent independent proximal policy optimization‐OLSR (MA‐IPPO‐OLSR), distributed multiple‐agent independent twin delayed deep deterministic policy gradient‐OLSR (MA‐ITD3‐OLSR) routing protocols. Since MA‐IDDPG‐OLSR relies only on local information, there is a minor performance degradation in MA‐IDDPG‐OLSR compared to centralized single‐agent DQN‐OLSR routing protocol. But it is more suitable to a completely distributed UAV network without a centralized node.
Estimation of shape memory alloy actuator dynamics to design reduced‐order position controller with input saturation
Authors: Shahir Mohammad Mohammadi , Mirzaei Mehdi , Farbodi Maryam , Rafatnia Sadra 
Published: April 2024

AbstractThis study focuses on the precise model estimation for a position control problem actuated by a shape memory alloy (SMA) wire. Because the hysteresis characteristic of SMA introduces complexities in system modelling and adds degrees of freedom, a model with reduced order is implemented for controller design. This model is online updated by calculating a complementary term from the measured data to compensate for the SMA actuator dynamics and other parametric uncertainties. The position controller, derived from the formulated reduced‐order model, adapts itself to real conditions and is cost‐effective due to the use of only displacement sensor. The saturation of the control input is modelled within the structure of a constrained optimization problem solved by Karush–Kuhn–Tucker theorem. The boundedness of mean and covariance of tracking error and its derivative is demonstrated by stochastic analysis. The experimental results conducted on a platform incorporating a SMA wire show the efficiency of the proposed system in precisely controlling the position by admissible voltage range. The comparative results with a sliding mode controller indicate higher accuracy for the proposed controller to reduce the effect of uncertainties.
Theoretical study on Stark effect of Rydberg atom in super low frequency electric field measurement

Published: April 2024

AbstractSuper low frequency electric field measurements are crucial in analysing electromagnetic compatibility, assessing equipment status, and other related fields. Rydberg atom‐based super low frequency electric field measurements are performed by observing the Stark shift in the spectrum of the Rydberg state. In a specific range of field strength (E < Eavoid, where Eavoid is the threshold to avoid crossing electric fields), the Rydberg atomic spectrum experiences a quadratic frequency shift in relation to the field strength, with the coefficient being determined by the atomic polarisability α. The authors establish a dynamic equation for the interaction between the external electric field and the atomic system, and present the Stark structure diagram of the Caesium Rydberg atom. The mathematical formulae for α and Eavoid in different Rydberg states are also obtained: α = A × (n*)6 + B × (n*)7 and Eavoid = C/(n*)5 + D/(n*)7, where A(B) = 2.2503 × 10−9(7.49,948 × 10−11) and C(D) = 1.68,868 × 108(2.45,991 × 109). The error of α and Eavoid compared with the experimental values does not exceed 8% and is even lower in the low Rydberg states. Accurately calculating the values of α and Eavoid is crucial in incorporating the Rydberg atom quantum coherence effect into super low frequency electric field measurements in new power systems.

Published: April 2024

AbstractPrecisely locating the voltage sag sources is significant for improving power quality and clarifying the responsibilities of both power supply and consumption. However, the existing location models are complex, computationally intensive, and influenced by the measurement error and fault type, which have low positioning efficiency and large errors. Therefore, this paper proposes a method for locating voltage sag sources based on power polarity and twin characteristics matching. The method firstly uses the polarity of the sequence sag component disturbance reactive power at the monitoring point to determine the sag line. Secondly, the basic realization method of the twin power system is discussed, and the twin characteristics are defined by combining the positive and negative sequence sag component disturbance reactive power and the twin database is established. Thirdly, the spectral norm and Pearson product‐moment correlation coefficient are used to define the data matching degree, and the precise location model of the sag source is established with the objective function of maximizing the data matching between the twin characteristics of the preset and actual sag. Finally, the Improved Whale Optimization Algorithm is used to solve the location model. The correctness and superiority of the proposed method is verified based on IEEE33 node modelling.
Diagnostik und Klassifikation der axialen Spondyloarthritis (axSpA) – der aktuelle Stand
Authors: Braun Jürgen , Poddubnyy Denis 
Published: April 2024

ZusammenfassungDie axiale Spondyloarthritis (axSpA) ist eine entzündlich-rheumatische Erkrankung, die typischerweise durch entzündlichen Rückenschmerz (eRs) gekennzeichnet ist. Der Terminus axSpA hat den lange gebräulichen Begriff ankylosierende Spondylitis (AS) weitgehend abgelöst. Der eRs ist durch Entzündung im Achsenskelett bedingt, wobei die Sakroiliakalgelenke (SIG) initial besonders häufig betroffen sind. Meist in späteren Stadien kommt die Wirbelsäule hinzu, was strukturell dann zunehmend durch Knochenneubildung gekennzeichnet ist. Zum Gesamktonzept der Spondyloarthritiden gehören weitere Krankheitsmanifestationen wie Uveitis, Psoriasis und Colitis und Komorbiditäten wie kardiovaskuläre Erkrankungen und Osteoporose.Für die axSpA gibt es seit 2009 die ASAS-Klassifikationskriterien, die die 1984 modifizierten New York-Kriterien abgelöst haben. Bei ersteren spielen über das konventionelle Röntgen hinaus erstmals mit Magnetresonanztomographie (MRT) festgestellte Veränderungen in der Bildgebung der SIG und auch der Nachweis von HLA B27 eine Rolle. Wichtig ist, dass es sich nicht um diagnostische Kriterien handelt, denn die gibt es nicht. In dieser Arbeit werden 10 Punkte aufgezeigt, die bei der Diagnosestellung berücksichtigt werden sollten.

Weiterhin weisen die Ergebnisse auf einen hohen Bedarf an Post-COVID-Ambulanzen und die Notwendigkeit des Ausbaus dieses Versorgungsangebotes hin.
Manifesto for infrastructural thinking: Living with psychoanalysis in a glitch
Authors: Soreanu Raluca , Minozzo Ana 
Published: April 2024

AbstractThis paper is a manifesto for an infrastructural turn in psychoanalysis, proposing to look at institutions ‘slantwise’. It theorises psychoanalytic infrastructural thinking, pondering on its qualities as a particular kind of orientation to action, and showing its capacity to consider multiple transferences and ambivalence, as well as new fantasies on gain, accumulation and redistribution. It articulates the relationship between infrastructural thinking and a postural theory of the subject, centred on considering inclinations, orientations, and disorientations in relation to objects. Drawing on ethnographic and archival material, it constructs a ‘scene’ for observing infrastructural thinking at work, in psychoanalytic free clinics in Brazil, in the 1970s, and up to our times. It looks at the infrastructural creativities of the free clinics, which promise to renew the relationship of psychoanalysis with itself and with its others. Exploring the intersection of psychoanalysis and phenomenology, it traces the work of infrastructural thinking in postural moments, glitches, disorientations, or slips of the tongue.
Activists and activism success: towards a grounded conceptualisation
Authors: Rye Danny 
Published: April 2024

AbstractSuccess is an important aspect of evaluating activism because the latter is a vehicle for political change. However, the idea of ‘success’ has proved difficult to capture in easily measurable ways. This has led some analysts to overlook its complexities and others to avoid the idea altogether, instead focusing on impacts, consequences and other seemingly less loaded terms. The definition of activism success therefore remains unsettled and under-studied. This article argues that an important perspective in evaluating activism is that of the activists themselves. What constitutes success (or not) for them must be an important consideration in defining and analysing it because it underpins the sense of purpose and value they put on what they do and helps to sustain them in the longer term. A workshop conducted with grass-roots activists in Liverpool provides useful insights towards this. The analysis of their reflections on successful activism suggests that it is still an important idea, but a complex and nuanced one that is multi-dimensional, political and contested. It reflects attitudes to a wider range of outcomes, the value of participation and attitudes to power, factors that analysts should consider incorporating into future studies.
