Near-infrared broadband luminescence from 1100 to 1600 nm was observed in Bi2O3-GeO2 binary glasses. The strongest emission can be with 30 mol % Bi2O3 when pumped at 808 nm. lifetimes of all samples are longer than 200 μs. glass network studied by Raman spectra and Bi+ ions proposed as the infrared centers this system. Thermal treatment air results partly oxidation Bi2+.
With advantages of reduced coupling and compact structure, Matrix Coils (MCs) design extension to approximate multiple target inhomogeneities is necessary improve its performance in shimming applications.A Spherical Harmonics Decomposition Method (SHDM) proposed for the multi-target MCs optimization problem. The magnetic field generated by represented form SHs' orthogonal basis, based on which pattern optimized adapt SH targets.With SHs 1st, 3rd, mixed 1st&2nd degrees Halbach magnet...
Large Language Models (LLMs) have demonstrated remarkable capabilities across a variety of tasks in different domains. However, they sometimes generate responses that are logically coherent but factually incorrect or misleading, which is known as LLM hallucinations. Data-driven supervised methods train hallucination detectors by leveraging the internal states LLMs, trained on specific domains often struggle to generalize well other In this paper, we aim enhance cross-domain performance with...
With advantages of small volume, high field strength, and compact stray field, the Halbach array magnet is great potential in desktop NMR applications. However, inhomogeneity poses a main obstacle to its Active shimming necessary for improving homogeneity. An active shim coil design method cylindrical based on inverse boundary element (iBEM) introduced this work. Shim coils targeting 1st∼3rd Z4/Z5/Z6 spherical harmonic (SH) terms were designed with constraints accuracy, resistance,...
Ultra-low field magnetic resonance imaging (ULF MRI) is an effective technique that applies the ultrasensitive detector of superconducting quantum interference device (SQUID) sensor to detect MR signal at a microtesla range. In this work, we designed and developed SQUID-based ULF MRI system with frequency-adjustable measurement field, performance which was characterized via water phantoms. order enhance signals, 500 mT Halbach magnet used prepolarize magnetization sample prior excitation....
