Multi‐Risk‐Level Sarcopenia‐Prone Screening via Machine Learning Classification of Sit‐to‐Stand Motion Metrics from Wearable Sensors

Advanced Intelligent Systems, EarlyView.
A machine learning approach utilizes micro inertial measurement units (μIMUs) for noninvasive sarcopenia screening through a sit‐to‐stand test. With 53 older participants wearing IMUs, 510 features are extracted across four motion phases. Five algorithms (support vector machine, K‐nearest neighbors, decision tree, linear discriminant analysis, and ...

Liveness‐Verified Dynamic Time Warping‐Based Authentication and Hybrid Adaptive Neuro‐Fuzzy Inference System Identification for Single‐Channel Diaphragmatic Breathing Surface Electromyography Biometrics

Advanced Intelligent Systems, EarlyView.
The first biometric framework to harness dynamic time warping (DTW) for single‐channel diaphragmatic surface electromyography authentication via post‐hoc alignment is presented. By optimally warping deep–normal–deep breath cycles, DTW achieves perfect genuine–impostor separation (equal error rates = 0%), while a parallel adaptive neuro‐fuzzy inference ...

Memimpedance‐Based Biomolecular Device for Adaptive Physical Reservoir Computing

Advanced Intelligent Systems, EarlyView.
By integrating fast‐switching ion‐channel‐based memristive and slow‐switching biomembrane‐based memcapacitive nodes within droplet interface bilayers, this hybrid memimpedance reservoir overcomes the memory‐nonlinearity trade‐off and extends temporal adaptability.

Light‐Mediated Decomposition of Arylseleninic Acids in Aqueous Medium: A Green Alternative Toward Organoselenium‐Functionalized Imidazo[1,2‐a]pyridines

Asian Journal of Organic Chemistry, EarlyView.
A new protocol to prepare 2‐aryl‐3‐(arylselanyl)imidazo[1,2‐a]pyridines under blue light irradiation, using benzeneseleninic acid derivatives as selenium source, is described. The experimental design approach (DoE) was used to establish the best reaction conditions, which delivered fourteen derivatives in moderate to good yields (23%–75%) using water ...

On the Ulam-Hyers stability of a quadratic functional equation

Journal of Inequalities and Applications, 2011
The Ulam-Hyers stability problems of the following quadratic equation r 2 f x + y r + r 2 f x - y r = 2 f ( x ) + 2 f ( y ) , where r is a nonzero rational number, shall be treated.
