Abstract: A system for predicting immunotherapeutic efficacy for colorectal cancer performs operations of: obtaining a digital image of a biological tissue a colorectal cancer patient; predicting a tissue type parameter and a cell type parameter corresponding to the digital image of the biological tissue based on a classifier algorithm model; determining a plurality of cell feature parameters corresponding to the digital image of the biological tissue based on a calculating rule of a plurality of cell features corresponding to the tissue type parameter and the cell type parameter; calculating a therapeutic efficacy score corresponding to the colorectal cancer patient according to the plurality of cell feature parameters and a predetermined parameter scoring rule; and the therapeutic efficacy score is configured to predict the therapeutic efficacy of the colorectal cancer patient receiving immunotherapy.

Abstract: A wideband circularly polarized antenna, comprising a ground plane, a radiating element and a plurality of metallic plates; the radiating element is defined above the ground plane, the metallic plates are sequentially and vertically defined around the ground plane, and displacements from the metallic plates to the center of the ground plane are the same. The wideband circularly polarized antenna provided by the present invention has a broad bandwidth and a compact configuration.

Abstract: The present invention relates to a process and a device for chlorine-free shrinkproof treatment of a wool raw material and an article thereof. In particular, the process of the present invention comprises the steps of a chlorine-free shrinkproof treatment, washing with water, protease inactivation, a softening treatment, dehydration, drying and the like, wherein a chlorine-free catalysis system consisting of a protease, a specific organic phosphine compound and the like is selected, removing the scale layer on the surface of wool fibres cooperatively and efficiently and modifying the scale layer so as to improve the shrinkproof performance of wool articles. The process of the present invention can completely replace the chloridisation shrinkproof method in the prior art, and is not only environmentally friendly, but also has low requirements for equipment, can be operated continuously and is suitable for large-scale industrial production.
