Degenerative valvular heart disease (VHD) is the predominant form of valvular heart lesions in Western countries, primarily occurring in individuals in their fifth decade and beyond, with aortic valve stenosis (AS) being the most prevailing manifestation.1 The aging population has contributed to a rapid increase in the incidence of degenerative VHD, with AS incidence rate increasing seven-fold over the last three decades.2 Despite the growing epidemic trend and significant disease burden,...

(1)Frame-field [27] is a building polygon extraction method proposed in 2020. It aligns the predicted frame field with the true outline. We implemented the model based on the code of the original paper. In our experiments, the frame-field was trained on a training set composed of samples from Wenzhou and was tested on a test set constructed from samples from Wenzhou;(2)Model_1 (Baseline) was trained on a training set composed of samples from Wenzhou using the HiSup model.

Super Asymmetric Cross Antenna Structure with Tunable Dual-Frequency Resonance The detection performance of traditional infrared spectroscopy can be very limited in the case of molecular vibrational modes with low absorption cross-sections. On account of its electric field enhancement, plasmonic antenna can be combined with the infrared spectroscopy to realize surface enhanced infrared detection and characterization of molecules.
