This study proposes an image segmentation method based on bottleneck detection and watershed algorithm to solve the problem of overlapping cervical cell image. First, we use polygon approximation to get all feature points on the cell contour and then use bottleneck detection and ellipse fitting to obtain the correct split point pairs. Therefore,…[Read more]

Diffuse ground-glass opacification and poorly defined ground-glass centrilobular nodules were seen on high-resolution computed tomography in one patient and three patients, respectively. All patients were suspected of having idiopathic pulmonary hemosiderosis or interstitial lung disease at other hospitals. All of them received treatment with…[Read more]

Spectral measurements of boundary-localized topological modes are commonly used to identify topological insulators. For high-order insulators, these modes appear at boundaries of higher codimension, such as the corners of a two-dimensional material. Unfortunately, this spectroscopic approach is only viable if the energies of the topological modes…[Read more]
