A Blind Source Extraction Method based on Self-learned Dictionary and Its Application in Fault Diagnosis of Bearing Multi-type Fault

Jixie chuandong, 2022
When multiple bearings in a gearbox failure simultaneously，conventional blind source extraction （BSE） on the vibration signals of bearing multi-type faults would not be ideal due to the mutual coupling effect among each of the fault sources.

Unveiling α‐MoO3 as a High‐Index, Low‐Loss Anisotropic Material: Bridging the Gap From Mid‐Infrared to Ultraviolet Nanophotonics

Advanced Materials, Volume 38, Issue 49, 1 September 2026.
α‐MoO3 is established as a high‐index, low‐loss anisotropic platform bridging mid‐infrared polaritonics and ultraviolet‐visible nanophotonics. Spectroscopic ellipsometry and calculations reveal refractive indices exceeding 3.9, with the largest in‐plane birefringence among transparent layered crystals at 425–500 nm, enabling zero‐order UV waveplates ...

Electromagnetic Radiation Stimulated Learning in Perovskite Nickelates

Advanced Science, Volume 13, Issue 49, 3 September 2026.
ABSTRACT Biological plasticity refers to the ability of synapses to strengthen or weaken over time. These adaptive properties play a fundamental role in learning and memory, spanning many orders of magnitude in timescales. Short‐term plasticity (STP) arises from rapid correlative activity, while long‐term plasticity (LTP) is governed by slower ...

Self-beliefs and bullying : unravelling the relation between bullying, being bullied and self-concept for upper elementary school aged children

, 2006
Previous examinations of relations between bullying, victimisation, and self-concept have been flawed by erroneous research practices such as the un-attenuated use of dichotomous variables to measure relationships between continuous variables (Finger ...

Optical Windows for Transcranial Brain Imaging in Living Mice: Skull Thinning, Clearing, and Beyond

Advanced Science, Volume 13, Issue 52, 18 September 2026.
Longitudinal, noninvasive in vivo imaging is crucial for studying brain physiology. Advances in transcranial optical windows and multiphoton microscopy have improved imaging depth, but their performance often deteriorates over time. This work investigated various transcranial window approaches and found that skull regrowth limits image quality.
