Neuropsychological case studies involving putative impairment of the visuo-spatial sketch-pad component of Baddeley's (1986) working memory model have been uncommon, with our own investigation of case ELD still being one of the most comprehensive to date (Hanley, Pearson, & Young, 1990; Hanley, Young, & Pearson, 1991). A recent theoretical review by Morey (2018) has offered a critique of ELD's data that has sought to cast doubt on our claim that she showed a pattern that reflects a problem with a functional component equivalent to the visuo-spatial sketch-pad. The importance of neuropsychological evidence to understanding visuo-spatial short-term memory has prompted us to revisit this case study, correct errors and misunderstandings in Morey's (2018) description of it, and provide some additional statistical information. Whilst acknowledging that cognitive neuropsychological studies will often depend on more than a single patient to offer definitive resolution of such an important issue, we show that there are compelling reasons to reject many of the claims that Morey (2018) made about ELD.

Cardiac arrhythmias are major global health concern and their early detection is critical for diagnosis. This study comprehensively evaluates the effectiveness of CNNs and LSTMs for the classification of cardiac arrhythmias, considering three PhysioNet datasets. ECG records are segmented to accommodate around ∼10s of ECG data.

SrFeO (SFO) offers a topotactic phase transformation between an insulating brownmillerite SrFeO (BM-SFO) phase and a conductive perovskite SrFeO (PV-SFO) phase, making it a competitive candidate for use in resistive memory and neuromorphic computing. However, most of existing SFO-based memristors are nonvolatile devices which struggle to achieve short-term synaptic plasticity (STP). To address this issue and realize STP, we propose to leverage ferroelectric polarization to effectively draw ions across the interface so that the PV-SFO conductive filaments (CFs) can be ruptured in absence of an external field.

Introduction: One of the possible treatment options for patient with cognitive dysfunction is cognitive telerehabilitation. Previous systematic reviews on cognitive telerehabilitation have focused on specific disease groups and the analysis of intervention methods did not differentiate between traditional face-to-face cognition treatment and usual care. In this systematic review, we aim to analyze randomized controlled trials (RCTs) that compare telerehabilitation with face-to-face treatment or usual care for improving cognitive function in elderly individuals with cognitive dysfunction or patients with acquired brain injury.

Introduction: Accurate prediction of knee biomechanics during total knee replacement (TKR) surgery is crucial for optimal outcomes. This study investigates the application of machine learning (ML) techniques for real-time prediction of knee joint mechanics.
Methods: A validated finite element (FE) model of the lower limb was used to generate a dataset of knee joint kinematics, kinetics, and contact mechanics.
Inflammation and cognitive performance in elite athletes: A cross-sectional study.

Justus-Liebig University Giessen, Germany.
Functional cognition is relevant for athletic success and interdependent with physical exercise, yet despite repeatedly demonstrated inflammatory responses to physical training, there are no studies addressing the relationship between cognition and inflammation in athletes. The aim of this study was to investigate the relationship between cognitive performance and selected inflammatory, and further physiological biomarkers in elite athletes. Data from 350 elite athletes regarding cognitive performance (processing speed, selective attention, working memory, cognitive flexibility), systemic inflammatory markers, metabolic hormones, growth factors, tissue damage markers, and micronutrients (e.
