Bridging the gap: a genetically validated avian chorioallantoic membrane platform for investigation of spontaneous circulating tumor cells

Molecular Oncology, EarlyView.
We established the avian chorioallantoic membrane (CAM) assay as a scalable in vivo model for studying circulating tumor cells (CTCs). Human gastrointestinal tumors spontaneously released genetically validated CTCs that were detected across multiple platforms, demonstrating that the CAM model provides an accessible tool for investigating early cancer ...

Infrared Tall Patch-Matrix Model for Single-Frame Low-Contrast Small Target Detection

Applied Sciences
Infrared small target detection (IRSTD) task is vital in practical applications. It is still a challenge when the target size is very small and the local signal-to-noise ratio is particularly low.

Adaptive optics point spread function reconstruction directly from target data

, 2016
Paper AOT2C.1, 3 S.Reconstruction of point spread function (PSF) using information from the wavefront sensor is a classic problem in adaptive optics. Although the theory and methods for this task have been in use for the last twenty years, implementation
