Diffractive Neural Networks (DNNs) leverage the power of light to enhance computational performance in machine learning, offering a pathway to high-speed, low-energy, and large-scale neural information processing. However, most existing DNN architectures are optimized for single tasks and thus lack the flexibility required for the simultaneous execution of multiple tasks within a unified artificial intelligence platform. In this work, we utilize the polarization and wavelength degrees of freedom of light to achieve optical multi-task identification using the MNIST, FMNIST, and KMNIST datasets.

The application of low-salt fish sauce is limited by its tendency to spoil easily and inadequate flavor generation. Herein, a salt-tolerant Tetragenococcus halophilus 2MH-3 strain with strong abilities of enzyme production and biogenic amine degradation was utilized as a starter for the production of low-salt fish sauce. Bacterial community analysis revealed discrepancies in microbiota between low-salt fish sauces fermented with (Th group) or without 2MH-3 (LF group).

Surface-enhanced Raman scattering (SERS) is widely used for trace detection of substances, and the key to this technology lies in the preparation of the substrate material. In this study, a composite SERS material of Au NRs/4-MBA/PAM was constructed and characterized to better immobilize the reference molecule 4-mercaptobenzoic acid (4-MBA). Electron transmission microscopy results demonstrated that the PAM film helps Au NRs to pack closely, enhancing the stability of the material structure and reducing the interference of external environmental factors on the response of 4-MBA, thus improving the accuracy of quantitative determination.

This study investigated the immunoregulatory activity of exopolysaccharides (EPS) produced by Lacticaseibacillus rhamnosus ZFM216 in immunosuppressed mice induced by cyclophosphamide (CTX). The results showed that EPS treatment effectively improved the body weight, immune organ index and splenic lymphocyte proliferation. EPS also mitigated the damage of immune organs, restored intestinal morphology, and regulated the levels of serum hemolysin and cytokines (e.

Article Synopsis
  • Circulating triglycerides (TG) and leukocytes are interconnected, potentially influencing the development of atherosclerosis, but their causal relationship is still unclear.
  • A bidirectional Mendelian randomization analysis and a cross-lagged panel model were used to investigate the relationship between TG levels and various leukocyte counts in a study of 13,389 adults over four years.
  • The findings indicated that elevated plasma TG levels are causally related to increased total leukocyte, lymphocyte, and neutrophil counts, while lymphocyte counts also positively influence plasma TG levels, suggesting a complex interplay where elevated lymphocytes may precede high triglyceride levels.

Tumor immunotherapy characterized by its high specificity and minimal side effects has achieved revolutionary progress in the field of cancer treatment. However, the complex mechanisms of tumor immune microenvironment (TIME) and the individual variability of patients' immune system still present significant challenges to its clinical application. Immunocyte membrane-coated nanocarrier systems, as an innovative biomimetic drug delivery platform, exhibit remarkable advantages in tumor immunotherapy due to their high targeting capability, good biocompatibility and low immunogenicity.

We computationally and analytically investigate the plasmon near-field coupling phenomenon and the associated universal scaling behavior in a pair of coupled shifted-core coaxial nano-cavities. Each nano-cavity is composed of an InGaAsP gain medium sandwiched between a silver (Ag) core and an Ag shell. The evanescent coupling between the cavities lifts the degeneracy of the cut-off free transverse electromagnetic (TEM) like mode.
