An Adaptive Pitch Control Strategy for Wind Turbines Using PIO‐Optimized Parallel Observation Deviation‐Coupled Linear Active Disturbance Rejection Control

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
This study proposes a parallel observation deviation‐coupled linear active disturbance rejection control (PODC‐LADRC) strategy optimized by a pigeon‐inspired optimization algorithm to mitigate asymmetric aerodynamic loads in large‐scale wind turbines. By utilizing a decoupled observation architecture, the proposed method reconstructs total disturbances

Unstained Blood Smear Analysis: A Review of Rule‐Based, Machine Learning, and Deep Learning Techniques

open access: yesJournal of Biophotonics, Volume 18, Issue 10, October 2025.
Bright‐field images of unstained smears. (1) Sparse erythrocytes allow straightforward intensity‐ or phase‐based segmentation. (2) Overlapping cells blur boundaries, causing over‐ or under‐segmentation and lowering rule‐based accuracy, thus motivating overlap‐aware algorithms for reliable downstream feature extraction and classification. ABSTRACT Blood

Effects of acoustic features modifications on the perception of dysarthric speech - preliminary study (pitch, intensity and duration modifications) [PDF]

open access: yes, 2017
Marking stress is important in conveying meaning and drawing listener’s attention to specific parts of a message. Extensive research has shown that healthy speakers mark stress using three main acoustic cues; pitch, intensity, and duration.

Unraveling the Hierarchical Self‐Assembly of Amphiphilic Block Copolymer‐Peptide Conjugates by Tip‐Enhanced Raman Spectroscopy

open access: yesSmall, Volume 21, Issue 32, August 14, 2025.
This study investigates peptide‐functionalized block copolymers forming wormlike micelles. Atomic force microscopy (AFM) and tip‐enhanced Raman spectroscopy (TERS) reveal that β‐sheet structures at the polymer interface enhance hierarchical organization. The peptide linker increases micelle contour length and bending stiffness.
