We report a search for neutrino oscillations to sterile neutrinos under a model with three active and one sterile neutrinos (3+1 model). This analysis uses the NOvA detectors exposed to the NuMI beam, running in neutrino mode. The data exposure, 13.

We propose a novel, to the best of our knowledge, compact, tilted silicon waveguide crossing designed using inverse design methods, specifically optimized to minimize both insertion loss and crosstalk. Through adjoint optimization algorithms and finite-difference time-domain simulations, we achieve a significant reduction in crosstalk from -46 dB at 90° to -54 dB at 86°, with a remarkably low insertion loss of -0.

Purpose: The distribution of cervical bones in ankylosing spondylitis (AS) differs from that of the normal cervical spine. Traditional simulation methods often yield inaccurate results in finite element analysis. The current study aimed to construct ankylosing spondylitis cervical spine fracture (ASCF) models based on Hounsfield Unit (HU) values to analyze the effects of different fixation approaches.

Hydrogen (H2) has demonstrated potential in scavenging excess ROS and correcting redox imbalances, while oxygen supplementation can alleviate hypoxia, promoting inflammatory remission. This study introduces a novel FA-HA-PtPdCo-TiO (F-HPPCT) nano-system for targeted RA therapy.
