Non-reciprocal response in silicon photonic resonators integrated with 2D CuCrP₂S₆ at short-wave infrared

Researchers integrated 2D CuCrP₂S₆ onto silicon microring resonators, achieving compact, efficient non-reciprocal optical response with low insertion loss and high isolation. The device operates directly in the transverse electric mode, eliminating polarization rotators and simplifying integration.

Bispecific killer engager for targeted depletion of PD-1 positive lymphocytes: A new avenue for autoimmune disease treatment

Researchers developed a bispecific killer engager that selectively depletes PD-1 positive lymphocytes, a promising avenue for treating autoimmune diseases. The bike technology enhances NK cell-mediated apoptosis and depletion of activated immune cells, supporting its potential as a safe and potent tool.

Towards hand gesture recognition using a channel-wise cumulative spike train image-driven model

A novel channel-wise cumulative spike train image-driven model (cwCST-CNN) is presented for hand gesture recognition, achieving a classification accuracy of 96.92% in recognizing 10 gestures. The method leverages HD-sEMG signals and reconstructs them into two-dimensional images to capture spatial activation patterns.

A retrospective cohort study of the efficacy and safety of oral azvudine versus nirmatrelvir/ritonavir in elderly hospitalized COVID-19 patients aged over 60 years

A retrospective cohort study found that azvudine treatment was not inferior to Paxlovid in terms of all-cause death, composite disease progression, and adverse events in elderly hospitalized COVID-19 patients. The study also suggested a greater benefit of azvudine over Paxlovid for patients with primary malignant tumors.
