Triboelectric–Electromagnetic Generator‐Enabled Hybrid Power Backpack for Self‐Powered Field Safety Management

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A lightweight hybrid backpack integrating SC‐TENGs and R‐EMGs harvests biomechanical energy during walking. With a low activation speed of 3 km h−1 and a high specific power of 0.18 W kg−1, it enables self‐powered field safety management. The power backpack refers to an energy‐harvesting solution engineered to mitigate battery reliance in wearable ...

From the sea to DNA barcode: Optimized preservation method for gelatinous zooplankton integrative taxonomy

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Voice and Speech in Atypical Parkinsonian Disorders

open access: yesMovement Disorders Clinical Practice, EarlyView.
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.

A Novel Optimized Local Linearization Hybrid Block Method for Chaotic Systems: Applications to Stretch‐Twist‐Fold Flow and Bond Orbital Chaotic Attractors

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The numerical approximation of nonlinear chaotic differential systems, such as the modified stretch‐twist‐fold (STF) flow and multi‐bond chaotic attractors, presents a significant challenge due to their sensitive dependence on initial conditions and complex dynamics where analytical solutions are unattainable.
