On the Design of a Class of Analog Filters Whose Impulse Response Is a Mittag‐Leffler Function

International Journal of Circuit Theory and Applications, EarlyView.
Fractional‐order filters whose impulse response is a Mittag‐Leffler (M‐L) function in any of its known forms are summarized in this work. Simulation results using Cadence and experimental results using an FPAA validate the introduced concept. ABSTRACT Fractional‐order filters whose impulse response is a Mittag‐Leffler (M‐L) function in any of its known

An Ultra‐Low‐Power Biopotential Acquisition Analog Front‐End Chip for Wearable Devices

International Journal of Circuit Theory and Applications, EarlyView.
A 0.8‐V, 1.2‐μW biopotential AFE combines a chopper‐stabilized CCIA with dual‐time‐scale EDO management. The slow DSL preserves > 1 GΩ input impedance, whereas an event‐triggered fast‐recovery path shortens return to the linear range after abrupt electrode‐offset disturbances. ABSTRACT A 0.8‐V, 1.2‐μW biopotential analog front‐end (AFE) IC is presented

Advances in vital‐sign prediction and early‐warning models for underground coal mine workers integrating environmental factors

Deep Underground Science and Engineering, EarlyView.
This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.

Progression and prognostic significance of electrocardiographic findings in patients with cardiac amyloidosis

ESC Heart Failure, Volume 12, Issue 2, Page 809-818, April 2025.
Abstract Aims This study aimed to evaluate the change of the main electrocardiographic (ECG) characteristics and their prognostic role across the main subtypes of cardiac amyloidosis [light‐chain amyloidosis (AL) and hereditary (ATTRv) and wild‐type transthyretin amyloidosis (ATTRwt)].

Transthyretin amyloid cardiomyopathy: Literature review and red‐flag symptom clusters for each cardiology specialty

ESC Heart Failure, Volume 12, Issue 2, Page 955-967, April 2025.
Abstract Wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating ...
