Development and User Experiences of a Novel Virtual Reality Task for Post-stroke Visuospatial Neglect : An Exploratory Case Study (Preprint)
No full textBackground: Visuospatial neglect (VSN) affects spatial awareness, leading to functional and motor challenges. This case study explores virtual reality (VR) as a potential complementary tool for VSN rehabilitation.
Objective: Specifically, we aim to explore the initial experiences of patients and physiotherapists engaging with a novel protocol, using an audiovisual cue task to support VSN rehabilitation.
Methods: A preliminary VR task integrating audiovisual cues was co-designed with 2 physiotherapists. The task was then tested with 2 patients with VSN over 12 sessions. The intervention focused on engaging neglected spatial areas, with physiotherapists adapting the task to individual needs and monitoring responses.
Results: Initial testing with 2 trainee physiotherapists indicated high usability, engagement, and perceived safety. Two patients with VSN completed 12 VR sessions. For Patient A, completion times increased following the introduction of an audio cue, though modeling indicated a nonsignificant linear trend (β=0.08; P=.33) and a marginally significant downward curvature (β=−0.001; P=.08). In contrast, Patient B showed a significant linear decrease in completion times (β=−0.53; P=.009), with a quadratic trend indicating a performance minimum around session 10 (β=0.007; P=.04). Intraweek variability also decreased. Motor scores (Box and Block Test and 9-Hole Peg Test) remained stable, and subjective feedback indicated improved mobility confidence and positive task engagement.
Conclusions: Further research with larger cohorts is needed to confirm the VR task’s utility and refine the intervention.peerReviewe
A machine learning approach to facilitate parasitic egg identification in a conspecific brood parasite
No full textAvian brood parasitism offers an excellent system for studying coevolution. While more common than interspecific parasitism, conspecific brood parasitism (CBP) is less studied owing to the challenge of detecting parasitic eggs. Molecular genotyping accurately detects CBP, but its high cost has led researchers to explore egg appearance as a more accessible alternative. Barn swallows (Hirundo rustica) are suspected conspecific brood parasites, yet parasitic egg detection has largely relied on subjective human assessment. Here, we used UV–visible photographs of genetically confirmed non-parasitized barn swallow clutches and simulated parasitism to compare the accuracy of human assessment with supervised machine learning models. Participants and models completed two classification tasks, identifying parasitic eggs from either six or two options. Both humans and the ‘leave-one-clutch-out’ model performed better than chance, with accuracies of 72 and 87% (humans) and 76 and 92% (models). An improved ‘leave-one-egg-out’ model achieved 97% accuracy, greatly exceeding human performance, likely by integrating more visual information, with egg dimensions being the most important trait, followed by colour and spotting pattern. We present a complete and accessible pipeline for replicating our supervised models, offering a powerful tool to identify parasitic eggs in other species also, and advance research on the evolution of egg phenotypes.peerReviewe
End-Edge Collaborative Control for AoI-Aware Short-Packet Industrial Cyber-Physical System
No full textAlong with the rapid development of the fourth industrial revolution, industrial cyber-physical systems (ICPS) are anticipated to achieve precise mapping and management for the physical world by integrating digital sensing and automated control. However, the conflict between limited computing resources and extensive sampling data, combined with severe industrial interference, exacerbates the system's processing burden and diminishes its accuracy, hindering its ability to meet the low-latency and high-reliability control requirements. To address this issue, this paper investigates an end-edge collaborative control framework to enhance control performance for a short-packet transmission ICPS by providing powerful computation capability. We utilize the age of information (AoI) to characterize the impact of information freshness on control accuracy and construct an AoI-aware control law to assist in data sensing, transmission, and computing strategy design. In addition, we consider the influence of sampling and short-packet decoding errors in AoI-aware control performance to enhance the reliability of sampling and transmission strategies design. A joint optimization scheme of sampling interval, sampling time, computation offloading, and bandwidth allocation based on the block coordinate descent method and game theory is proposed to achieve a tradeoff between the control cost and energy consumption. By considering a real-world trolley inverted pendulum manipulation model, numerical results verify the performance gain of the proposed end-edge collaborative framework and the effectiveness of the presented algorithm.peerReviewe
A determination of αs(mZ) at aN3LOQCD ⊗ NLOQED accuracy from a global PDF analysis
No full textWe present a determination of the strong coupling αs(mZ ) from a global dataset including both fixedtarget and collider data from deep-inelastic scattering and a variety of hadronic processes, with a simultaneous determination of parton distribution functions (PDFs) based on the NNPDF4.0 methodology. This determination is performed at NNLO and approximate N3LO (aN3LO) perturbative QCD accuracy, including QED corrections and a photon PDF up to NLO accuracy. We extract αs using two independent methodologies, both of which take into account the cross correlation between αs and the PDFs. The two methodologies are validated by closure tests that allow us to detect and remove or correct for several sources of bias, and lead to mutually consistent results. We account for all correlated experimental uncertainties, as well as correlated theoretical uncertainties related to missing higher order perturbative corrections (MHOUs). We study the perturbative convergence of our results and the impact of QED corrections. We assess individual sources of uncertainty, specifically MHOUs and the value of the top quark mass. We provide a detailed appraisal of methodological choices, including the choice of input dataset, the form of solution of evolution equation, the treatment of the experimental covariance matrix, and the details of Monte Carlo data generation. We find αs(mZ ) =0.1194+0.0007 −0.0014 at aN3 LOQCD⊗NLOQED accuracy, consistent with the latest PDG average and with recent lattice results.peerReviewe

Dataset of the project "Get Involved! Transition to Grade 1": Parent/Guardian Questionnaire Data
No full textDataset originates from the longitudinal research project “Get Involved! Transition to Grade 1” investigated the role of parents and teachers in the development of children’s academic achievement, motivation, and behaviour during the critical transition from preschool to primary school. The study aimed to provide information on the role of parents’ and teachers’ instructional support and affect in children’s outcomes which is crucial in promoting learning among students in school. The project sought to test a comprehensive model of child development in the early phase of schooling, considering both parental and teachers influences, as well as children’s evocative influence on their interpersonal environment. It examined the longitudinal relations between parents’ and teachers’ instructional support and emotions, and children’s outcomes across the transition from preschool to primary school. The study also aimed to identify cases in which such support had the most favourable outcomes for children’s achievement, motivation, and behaviour, and to determine the mechanisms by which those outcomes emerge.
Parent/Guardian questionnaire data collection took place in three waves:
a) Preschool, spring 2017 (T1)
b) Grade 1, fall 2017 (T2)
c) Grade 1, spring 2018 (T3)
Parent/Guardian questionnaire data included information on parents’ involvement in academic-related activities (e.g., homework), their emotional and cognitive perceptions regarding their children, their relationship with the child and so on. Additionally, parents/guardians provided information about their collaboration with preschool institution and so on.
The dataset consists of three separate SPSS files, each representing one wave of data collected through parent/guardian questionnaires during the study
Guidance practitioners’ approaches to building client relationships and solving institutional dilemmas in the Finnish public employment services
No full textThis article explores public employment service (PES) guidance practitioners’ interpretations of and approaches to building working relationships with their clients in the context of different kinds of institutional expectations placed on client work. The study was conducted in the context of the recently reformed Finnish PES and focused on new categories of practitioners in municipal service organisations. A discursive analysis of thematic interviews with practitioners (n = 16) identified four interpretative repertoires that were, namely, (1) the moral educative, (2) the holistic care, (3) the pragmatic alliance and (4) the socio-critical repertoire. These repertoires represent different ways of solving dilemmas, in particular, between holistic ideals of guidance and the prevailing outcome-focused expectations placed on client work within PES. The results shed light on how dilemmas embedded in guidance work within PES contribute to variation in approaches that practitioners take and may have consequences for service outcomes.peerReviewe
