Abstract: A housing having a woven appearance includes a substrate and a plurality of groove groups formed on the surface of the substrate. The groove groups define the woven appearance and are formed by etching. The housing may be made by using a film having a lightproof areas and a light-transmissible areas, the lightproof areas defining a woven appearance. The film is placed over a metal substrate having light-sensitive materials formed thereon and radiated with light. The light passing through the light-transmissible areas of the film solidifies the light-sensitive materials. After, removing the film from the substrate and cleaning un-solidified light-sensitive materials from the substrate to expose areas corresponding to the lightproof area, and an etching process is carried out to form the woven appearance on the exposed areas.

Abstract: A discriminative feature set (DFS) selection method is described wherein a forward wrapper framework and a self error-correction concept are used. In this approach, the first feature is selected using a statistical measure. After that, the feature that aims to correct the errors made by the current feature set is selected using a measure called correction score (CS) and is subsequently added into the feature set. This error-corrective feature-adding process stops until a required number of features are included into the DFS or a pre-defined accuracy is achieved. According to different levels of error correction, this method has three derivatives for different tasks and data. The speediness and adaptability of this approach make it efficient and effective for high-dimensional discriminative feature selection.

Abstract: A method is disclosed for cancer treatment based on using a solid polymer gel to completely block blood vessels of tumor. A polymer aqueous solution is injected into blood vessels and formed a solid gel in blood vessels of tumor by applying electromagnetic radiation or temperature source at tumor tissue to inducing crosslinking or phase transition. The tumor cells starve and perish because of without nutrients and oxygen provided by vascularization and metastasis can also be prevented because polymer gels blocks tumor cells to shed into blood circulation, when the blood vessels of tumor are completely blocked by the solid polymer gels. Also, anti-cancer drug including chemotherapy drug, radiation drug or anti-angiogenic drug can be mixed or conjugated with the polymer in polymer aqueous solution to be locally delivered to the tumor after polymer gel formation in the blood vessels of tumor of human or animal.
