Design of HAWT Rotor for Non‐Uniform Inflow Conditions: A Theoretical and Experimental Approach for Shear Flow

open access: yesEnergy Science &Engineering, EarlyView.
This paper aims to provide a robust design approach for HAWTs operating in shear flow. This study fills a critical research gap by integrating BEM and vortex theories for blade design in non‐homogeneous inflow conditions. The authors of the paper made an effort to develop and test an experimentally unsophisticated model of a turbine working in shear ...

Electronic jelly: Engineering the mechanics of hydrogels for flexible electronics

open access: yesFlexMat, EarlyView.
By unifying mechanical reinforcement strategies—double networks, structural ordering, and dynamic interactions—this review demonstrates how engineered hydrogels can transcend their fragility to achieve the strength, toughness, and reliability required for flexible electronics, including wearable sensors, energy devices, and soft robotic systems ...

Variations in the Relationship Between the Frequency Content of EMG Signals and the Rate of Torque Development in Voluntary and Elicited Contractions

open access: yes, 2002
Our purpose was to characterize the relationship between EMG mean power frequency (MPF) or median frequency (MF) and rate of torque development in voluntary ballistic and electrically elicited isometric contractions.

Flexible ionic pressure sensors: From migration‐electronic mechanisms to emerging iontronic paradigms

open access: yesInfoMat, EarlyView.
Mechanisms, materials, structures, and applications of the FIPSs. Abstract Flexible ionic pressure sensors (FIPS) have emerged as promising candidates for bridging the gap between electronics and biologically compatible interfaces. Unlike previous reviews, which focused primarily on materials or devices, this review presents a classification of FIPS ...

Application Research of Microstructured Flexible Sensors in Rehabilitative Wearable Sensing

open access: yesiNew Medicine, EarlyView.
ABSTRACT Flexible sensors enable the continuous, real‐time monitoring of the physiological and movement signals of patients, providing data support for precise rehabilitation strategies and playing a crucial role in rehabilitation medicine. However, traditional rigid sensors are often incompatible with dynamic body contours due to their high material ...

Pulsed Electromagnetic Field Therapy for Mild-to-Moderate Knee Osteoarthritis: A Double-Blind, Randomized, Placebo-Controlled Clinical Trial. [PDF]

open access: yesJ Cachexia Sarcopenia Muscle
ABSTRACT Background Current treatments for knee osteoarthritis (OA) offer limited functional and structural improvements. Compared to age‐ and gender‐matched controls, patients with knee OA show a higher prevalence of muscle weakness, which negatively affects their ability to exercise—a key factor in enhancing physical mobility and delaying disease ...

Laser Absorption Shock Tube Study of C1 to C4 n‐Alkyl Formate Pyrolysis

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT n$n$‐Alkyl formates are considered as potential alternative fuels or fuel additives. While their oxidation chemistry has been investigated intensely, their pyrolysis chemistry requires more experimental insights. The present work utilizes shock tube experiments in combination with infrared laser absorption measurements to obtain information ...
