The high-grade glioma is characterized by cell heterogeneity, gene mutations, and poor prognosis. deletions mutations of the tumor suppressor PTEN (5%-40%) in patients are associated with worse survival therapeutic resistance. Characterization unique prognosis molecular signatures status still unclear. This study established a novel risk model, screened optimal prognostic signatures, calculated score for individual different status. Screening results revealed fourteen independent PTEN-wt...
We simulate and demonstrate experimentally an inner-wall grating double slot micro ring resonator (IG-DSMRR) with a center radius of only 6.72 µm based on the silicon-on-insulator platform. This novel photonic-integrated sensor for optical label-free biochemical analysis boosts measured refractive index (RI) sensitivity in glucose solutions to 563 nm/RIU limit detection value being 3.7 × 10 −6 RIU (refractive units).

Abstract Photoacoustic tomography (PAT) has emerged as a promising non-invasive imaging technology with significant potential for various clinical applications in medical settings. Traditionally, PAT utilizes single laser beam to generate the excitation light (Wang & Hu,2012). Nonetheless, this method often suffers from low signal-to-noise ratios (SNR) and poor image contrast due environmental noise other interfering factors. This paper introduces an interference technique designed focus...
Abstract Photoacoustic microscopy (PAM) is a novel non-invasive imaging technique that utilizes the endogenous optical absorption properties of sample to obtain structural and functional information about sample, has wide range applications in field bioimaging. However, there are few reports on position detection micrometallic materials using PAM. In this paper, method measure spatial metallic PAM proposed. Firstly, working principle realization introduced, experiments carried out copper...
Abstract In extreme space environments with alternating and uneven temperature variations, the surface accuracy of cable-net antennas deteriorates significantly, thereby inducing a periodic failure or significant deviation in electrical performance.
