Vibrations of a rotating piezoelectric body and applications in gyroscopes [PDF]

open access: yes, 2000
Based on the linear theory of piezoelectricity, analyses of a few basic problems associated with the vibration of a rotating piezoelectric body are performed with applications in piezoelectric gyroscopes for measuring the angular rate of a rotating body.

Evolutionary Computation Applied to the Tuning of MEMS Gyroscopes [PDF]

open access: yes, 2005
We propose a tuning method for MEMS gyroscopes based on evolutionary computation to efficiently increase the sensitivity of MEMS gyroscopes through tuning and, furthermore, to find the optimally tuned configuration for this state of increased sensitivity.

STELLAR‐CB: Synthetic Temporal LSTM for Livestock Activity Recognition—Cow Behaviour

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This study introduces a novel framework combining LSTM networks with SMOTE to address class imbalance in precision livestock farming. It improves the detection of rare behaviours in livestock, achieving state‐of‐the‐art performance while reducing computational overhead, offering a practical, breed‐agnostic solution for enhancing automated behaviour ...

Predicting and Rationalizing Piezoelectricity in Racemic Bioorganic Molecular Crystals

open access: yesAngewandte Chemie, Volume 138, Issue 26, 22 June 2026.
Racemic molecular crystals, composed of equal mixtures of chiral enantiomeric components, are predicted to exhibit significant piezoelectric responses and favourable mechanical flexibility. This study identifies organic and bioorganic racemates as promising candidates for sustainable, lead‐free materials, enabling next‐generation applications in energy

Statistical Study on Pulsating Auroras and High‐Latitude Propagation of Chorus Waves Based on Conjugate Observations of Ground‐Based Imagers and Arase Satellite

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract Pulsating aurora (PsA) is one of the common diffuse auroras typically generated by ∼10 keV electron precipitation. Precipitating electrons are scattered via wave‐particle interactions with whistler‐mode chorus waves in the magnetosphere. Previous studies have observationally demonstrated that, during PsAs, highly energetic electrons with ...

How Algorithmic Technologies ‘Constitute’ the Older Body: A Study of Fall‐Detection Wearables

open access: yesSociology of Health &Illness, Volume 48, Issue 6, July 2026.
ABSTRACT The cultural politics of the ‘problematic’ ageing body have led to a search for solutions in the form of algorithmic technologies. In this article, we look at one problem associated with the ageing body—unintentional falls—and one proposed algorithmic intervention: wearable fall‐detection technology.

Technologies for equine welfare and performance monitoring under field conditions – Where do we stand?

open access: yesEquine Veterinary Journal, Volume 58, Issue 4, Page 872-888, July 2026.
Abstract The need for comprehensive equine welfare assessments has become particularly evident amid ongoing debates about the social licence to operate in equestrian sports. During exercise, multiple physiological systems, principally the cardiovascular, respiratory, muscular, thermoregulatory, endocrine, and locomotory systems, undergo complex ...

Autonomous Frameless Spine Registration and Robot‐Assisted Surgery

open access: yesOrthopaedic Surgery, Volume 18, Issue 7, Page 1471-1490, July 2026.
Workflow of a contactless, frame‐free, robot‐assisted vertebra registration system. Preoperative CT data establish vertebra {V} and mask {Mpre} coordinate systems. Their relationship is computed, and intraoperatively the robot recognizes the skin‐affixed mask, defining {Mintra}.
