Machine‐Learning‐Enhanced Printed Vertical Magnetoresistive Sensors for Transparent, Flexible, Multimodal Interactive Magnetoelectronics

Advanced Science, EarlyView.
This study presents printed magnetoresistive sensors with a vertically aligned architecture that enables high optical transparency and mechanical flexibility. By integrating deep learning for the analysis of complex spatiotemporal signal patterns, the system further achieves intelligent multimodal interaction capabilities.

Transforming DIY Geiger Counter Kits into Muon Detectors for Education and Scientific Exploration

Particles
Any Geiger counter can be used as an effective cosmic ray detector on its own. In fact, it is known that even in the absence of a radioactive source, the instrument detects what is known as background radiation, which consists of various types of ...

Direct Observation of Vortex Liquid Droplets in the Iron Pnictide Superconductor CaKFe4As4 at 0.5Tc

Advanced Science, EarlyView.
Vortex matter in the iron‐based superconductor CaKFe4As4${\rm CaKFe}_4{\rm As}_4$ is visualized at the nanoscale, revealing the unexpected emergence of vortex‐liquid droplets far below the critical temperature. These localized fluctuating regions coexist with a vortex solid, demonstrating that dissipation‐related dynamics arise well before macroscopic ...

Kaempferol Attenuates Spaceflight‐Associated Knee Cartilage Degradation by Targeting NOX4‐Mediated Mitochondrial Dysfunction

Advanced Science, EarlyView.
We have shown that both simulated and actual spaceflight contribute to cartilage degradation in the knees of mice. Using RNA sequencing and bioenergetic profiling, we identified NADPH oxidase 4 (NOX4) as a key factor driving these changes. Additionally, we found that kaempferol, a naturally occurring flavonoid that binds directly to NOX4, reduces ...

DETECTION AND BLANKING OF GSM INTERFERENCE IN RADIO-ASTRONOMICAL OBSERVATIONS [PDF]

, 2008
Radio-astronomical observations are increasingly disturbed by man-made communication signals, satellite and broadcast services. In particular, the GSM band is a highly saturated domain, full with interferers which are much stronger than radio ...

Tests of commercial colour CMOS cameras for astronomical applications [PDF]

, 2013
We present some results of testing commercial colour CMOS cameras for astronomical applications. Colour CMOS sensors allow to perform photometry in three filters simultaneously that gives a great advantage compared with monochrome CCD detectors.

Low dark current Sb-based short-wavelength infrared photodetector

AIP Advances
We have theoretically and experimentally demonstrated the feasibility of achieving ultra-low dark current in CpBnn type detectors based on a double-barrier InAs/GaSb/AlSb type-II superlattice. By employing a structure that separates the absorption region

Plaid‐Like Spin Splitting and Chirality of Magnon Bands in Antiferromagnetic MnTe2

Advanced Science, EarlyView.
Helicity‐ and angle‐resolved Raman spectroscopy reveals chiral magnons in the non‐coplanar antiferromagnet MnTe 2. Combined with first‐principles calculations and spin‐wave theory, the results establish its altermagnetic character through circular Raman dichroism, reduced rotational symmetry, and a distinctive plaid‐like momentum‐space magnon spin ...
