Clustering analysis is traditionally considered as an unsupervised learning process. In most cases, people usually have some prior or background knowledge before they perform the clustering. How to use the prior or background knowledge to imporve the cluster quality and promote the efficiency of clustering data has become a hot research topic in recent years. The Must-Link and Cannot-Link constraints...
The aim of this study was to demonstrate the clinicopathological features, prognostic outcomes and fibroblast growth factor receptor 3 (FGFR3) protein expression status of a large series ( n = 45) of urothelial carcinoma of bladder patients aged 30 or younger, retrospectively. We identified an age gradient (an age of 25, 26 and 27 years), classified patients as ≤25 or >25, ≤26...
P-type copper phthalocyanine (CuPc) and n-type hexadecafluorophthalocyanina-tocopper (F16CuPc) polycrystalline films were investigated by Kelvin probe force microscopy (KPFM). Topographic and corresponding surface potential images are obtained simultaneously. Surface potential images are related with the local work function of crystalline facets and potential barriers at the grain boundaries (GBs)...
