Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

Advanced Materials, Volume 38, Issue 37, 2 July 2026.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

Gas Damping Coefficient Research for MEMS Comb Linear Vibration Gyroscope [PDF]

, 2007
Silicon-MEMS gyroscope is an important part of MEMS ( Micro Electrical Mechanical System). There are some disturb ignored in traditional gyroscope that must be evaluated newly because of its smaller size (reach the level of micron). In these disturb, the

Agreement of imageless navigation‐derived pelvic tilt measurements with radiographic and CT‐based measurements in direct anterior total hip arthroplasty: A prospective single‐center study

Journal of Experimental Orthopaedics, Volume 13, Issue 3, July 2026.
Abstract Purpose Pelvic tilt (PT) is a major determinant of functional acetabular orientation, affecting implant stability and impingement risk. Although imageless navigation systems are increasingly used to guide intraoperative cup orientation, their validity in measuring supine PT remains unclear.

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

Veterinary 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 ...

GPS-Aided Gyroscope-Free Inertial Navigation Systems [PDF]

A gyroscope-free inertial navigation system uses only accelerometers to compute navigation trajectories. It is a low-cost navigation system, but its output error diverges at a rate that is an order faster than that of a conventional gyroscope-based ...

Morphological Dating of Fluvial Terrace Risers Across Spatial and Temporal Scales

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Fluvial terraces are valuable terrestrial records of past climatic and tectonic changes. Morphological dating, which quantifies the degradation of the riser between two terraces, offers a relatively simple and cost‐effective alternative to other dating methods.

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

Journal 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 ...

Predicting and Rationalizing Piezoelectricity in Racemic Bioorganic Molecular Crystals

Angewandte 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
