An analysis of performance bottlenecks in MRI preprocessing

Author(s): Dugré M; Chatelain Y; Glatard T;

Magnetic resonance imaging (MRI) preprocessing is a critical step for neuroimaging analysis. However, the computational cost of MRI preprocessing pipelines is a major bottleneck for large cohort studies and some clinical applications. While high-performance computing and, more recently, deep learning have been adopted to accelerate the computations, these ...

The Effects of Weekly Levels of Supervisor Support and Workload on Next Week Levels of Well-Being, Satisfaction, and Performance as Mediated by Weekend Work Recovery

Author(s): Cheyroux P; Morin AJS; Colombat P; Blechman Y; Gillet N;

This diary study sought to examine the direct and indirect effects of individuals' perceptions of supervisor support and workload during a work week (week 1) on their well-being, satisfaction, and performance at work during the following work week (week 2) as mediated through the quality of their weekend work recovery experiences (psychological detach ...

Exploring the glycoprotein washing fluid-assisted cleanup for the restoration of oil-contaminated shorelines with environmental integrity

Author(s): Sui J; Yue R; Bi H; Fu H; Yang A; Wang M; An C;

Spilled oil in ocean can spread to the shoreline and cause long-term impacts on the shoreline's ecological environment. Therefore, removing oil accumulated on shorelines is crucial. This study proposed an innovative ovalbumin (OVA) fluid-assisted method for the cleanup of oiled shoreline substrates. The oil removal efficiency of OVA fluids was systema ...

A Survey on Error Exponents in Distributed Hypothesis Testing: Connections with Information Theory, Interpretations, and Applications

Author(s): Espinosa S; Silva JF; Céspedes S;

A central challenge in hypothesis testing (HT) lies in determining the optimal balance between Type I (false positive) and Type II (non-detection or false negative) error probabilities. Analyzing these errors' exponential rate of convergence, known as error exponents, provides crucial insights into system performance. Error exponents offer a lens thro ...

Effects of color cues on eye-hand coordination training with a mirror drawing task in virtual environment

Author(s): Alrubaye Z; Hudhud Mughrabi M; Manav B; Batmaz AU;

Mirror drawing is a motor learning task that is used to evaluate and improve eye-hand coordination of users and can be implemented in immersive Virtual Reality (VR) Head-Mounted Displays (HMDs) for training purposes. In this paper, we investigated the effect of color cues on user motor performance in a mirror-drawing task between Virtual Environment (VE) ...

Design optimization and experimental evaluation of a large capacity magnetorheological damper with annular and radial fluid gaps

Author(s): Abdalaziz M; Sedaghati R; Vatandoost H;

This paper presents an optimal design of a large-capacity Magnetorheological (MR) damper suitable for off-road vehicle applications. The damper includes an MR fluid bypass valve with both annular and radial gaps to generate a large damping force and dynamic range. An analytical model of the proposed damper is formulated based on the Bingham plastic model ...

Preparation, characteristics, and performance of the microemulsion system in the removal of oil from beach sand

Author(s): Bi H; Mulligan CN; Lee K; An C; Wen J; Yang X; Lyu L; Qu Z;

Oil deposited on shoreline substrates has serious adverse effects on the coastal environment and can persist for a long time. In this study, a green and effective microemulsion (ME) derived from vegetable oil was developed as a washing fluid to remove stranded oil from beach sand. The pseudo-ternary phase diagrams of the castor oil/water (without or witho ...

Class imbalance should not throw you off balance: Choosing the right classifiers and performance metrics for brain decoding with imbalanced data

Author(s): Thölke P; Mantilla-Ramos YJ; Abdelhedi H; Maschke C; Dehgan A; Harel Y; Kemtur A; Mekki Berrada L; Sahraoui M; Young T; Bellemare Pépin A; El Khantour C; Landry M; Pascarella A; Hadid V; Combrisson E; O' Byrne J; Jerbi K;

Machine learning (ML) is increasingly used in cognitive, computational and clinical neuroscience. The reliable and efficient application of ML requires a sound understanding of its subtleties and limitations. Training ML models on datasets with imbalanced classes is a particularly common problem, ...
