Segmentation of Brain Substantia Nigra Pars Compacta Based on Improved U-Net [PDF]
Jisuanji gongcheng, 2022 The segmentation of brain Substantia Nigra pars compacta(SNpc) can provide the basis for Parkinson's disease diagnosis.SNpc is a low-pixel-ratio object in Magnetic Resonance Imaging(MRI) of the human brain, and the pixels with different labels are ...

Solvability of Coupled Systems of Generalized Hammerstein-Type Integral Equations in the Real Line
Mathematics, 2020 In this work, we consider a generalized coupled system of integral equations of Hammerstein-type with, eventually, discontinuous nonlinearities. The main existence tool is Schauder’s fixed point theorem in the space of bounded and continuous ...

Solvable non-Hermitian skin effect in many-body unitary dynamics
Physical Review Research, 2022 We study unitary evolution of bipartite entanglement in a circuit with nearest-neighbor random gates. Deriving a compact nonunitary description of purity dynamics on qudits we find a sudden transition in the purity relaxation rate the origin of which is ...

Small facial image dataset augmentation using conditional GANs based on incomplete edge feature input [PDF]
PeerJ Computer Science, 2021 Image data collection and labelling is costly or difficult in many real applications. Generating diverse and controllable images using conditional generative adversarial networks (GANs) for data augmentation from a small dataset is promising but ...
