Abstract: The present invention provides an infrared pixel structure and a hybrid imaging device which use comb-shaped top plates and bottom plates to form capacitors. The upper electrode has a non-fixed end such that the infrared sensitive element in the upper electrode generates thermal stress and deforms when absorbing the infrared light, which changes the capacitance of the capacitors formed by the top plates and the bottom plates to achieve infrared detection and increase the device sensitivity. Furthermore, the infrared pixel structure can be used in an infrared light and visible light hybrid imaging device to achieve visible light imaging and infrared imaging in a same silicon substrate, so as to increase the imaging quality.

Abstract: The present disclosure provides mutant vaccinia virus strains that can selectively replicate in tumor cells. The present disclosure also provides use of the mutant vaccinia virus strains for preventing and treating tumors.

Abstract: The present disclosure provides tumor vaccines useful for preventing and treating tumors and cancers. The tumor vaccines may contain nucleic acids encoding for antigen presenting peptides, cytokines and other factors useful for preventing and treating tumors and cancers, or expression vectors or viruses containing such nucleic acids, or host cells containing such nucleic acids or expression vectors.
