Quantitative Diffusion and T2 Mapping Using RF‐Modulated Phase‐Based Gradient Echo Imaging

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To introduce and evaluate the feasibility of a novel RF‐phase modulated gradient echo (GRE) method for quantitative diffusion MRI, aimed at mitigating geometric distortion and enabling high‐resolution 3D quantitative diffusion/T2 mapping as a complementary alternative to conventional DWI.

Simultaneous Assessment of Intracranial Artery and Paravascular CSF Pulsation Using 3D Whole‐Brain Diffusion‐Prepared Cine bSSFP (DECAF) MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To propose a noninvasive and quantitative MRI approach to simultaneously assessing intracranial artery pulsation and paravascular cerebrospinal fluid (CSF) pulsation in the human brain. Methods We developed a 3D whole‐brain Diffusion‐prepared Cine bSSFP (DECAF) MRI technique, with improved motion‐sensitized driven‐equilibrium providing

Reachable Workspace as a Clinical Outcome for Upper Extremity Function: A Narrative Review

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Motion sensing technology can be utilized to capture detailed upper extremity (UE) motion to reconstruct an individual's three‐dimensional (3D) reachable workspace (RWS). The RWS can be quantified as relative surface area (RSA), providing an innovative surrogate measure to assess UE mobility and function.

The impact of COVID‐19 on public perceptions of wild meat in Central Africa

open access: yesPeople and Nature, EarlyView.
Abstract Wild meat is a significant source of food and income generation in Central Africa. However, there is little knowledge of how the assumed link between COVID‐19 and wild meat consumption has been discussed by the media and received by the public. In this study, we conducted media content analysis of 264 articles published in 2019–2020 related to

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

open access: yesJournal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.

Sliding Mode Control in Aerospace Applications: A Survey

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...
