Mechanoluminescence of Bi‐Activated NaYGeO4 Polycrystals and 3D Printed Scaffolds in the NUV/Blue and NIR Spectral Range

open access: yesAdvanced Optical Materials, EarlyView.
NUV/Blue and NIR emitting mechanoluminescent (ML) materials based on a Bi‐doped germanate compound (NYGOBx) are reported. 3D‐printing is used to fabricate complex scaffold devices from this material, suggested for use as mechanically‐activated light sources for functional illumination.

Halogen Bonding‐Enabled Stabilization of Copper(I) Cluster Scintillators in Aqueous Environments

open access: yesAdvanced Optical Materials, EarlyView.
A new class of halogen bonding‐strengthened copper(I) cluster‐based X‐ray scintillators is developed, with higher lattice symmetry, reduced trap density, and enhanced stability in polar chemical environments surpassing the performance of halogen‐free counterparts and other conventional scintillators. Abstract Scintillators are essential in applications,

Towards AI-driven Sign Language Generation with Non-manual Markers [PDF]

open access: yesarXiv
Sign languages are essential for the Deaf and Hard-of-Hearing (DHH) community. Sign language generation systems have the potential to support communication by translating from written languages, such as English, into signed videos. However, current systems often fail to meet user needs due to poor translation of grammatical structures, the absence of ...

Spherical and Aspherical Lenses for Boosting the Performance of Terahertz Imaging Systems

open access: yesAdvanced Photonics Research, EarlyView.
This study investigates the enhancement of terahertz (THz) detection through the terajet effect using mesoscale dielectric lenses of various geometries. Spherical, aspherical, and cubic polytetrafluoroethylene lenses are evaluated at 0.15 and 0.3 THz, demonstrating significant improvements in responsivity and noise reduction.

ProCom: A Few-shot Targeted Community Detection Algorithm [PDF]

open access: yesarXiv
Targeted community detection aims to distinguish a particular type of community in the network. This is an important task with a lot of real-world applications, e.g., identifying fraud groups in transaction networks. Traditional community detection methods fail to capture the specific features of the targeted community and detect all types of ...
