Thin?walled parts are widely used in many important fields because of performance and structural lightweight requirements. They critical they usually carry the core functions high?end equipment. However, their high?performance machining has been facing severe challenges, among which dynamics problem is one most obstacles. The system easily subjected to chatter due weak rigidity thin?walled stru...

Objective(s):Immunosuppressive property of mesenchymal stem cells (MSCs) has great attraction in regenerative medicine especially when dealing with tissue damage involving immune reactions. The most attractive tissue sources of human MSCs used in clinical applications are bone marrow (BM), adipose tissue (AT), and Wharton's jelly (WJ) of human umbilical cord. The current study has compared immu...

Businesses deploy chatter bots to engage in text based conversations with customers that are intended resolve their issues. However, these chatter bots are only effective in exchanges consisting of question answer pairs, where the context may switch with every pair. I am designing a semantic architecture that enables chatter bots to hold short conversations, where context is maintained througho...

Large-scale slender beam structures with low stiffness are widely used in the aviation field. There will be a great deformation problem machining because overall of parts is lower. Firstly, cutting mechanism and stability theory Ti6Al4V material analyzed, then auxiliary support carried out according to characteristics structure. The feasibility suppression measures for verified by experiments. ...

Chatter bots are software programs that engage in artificial conversations through a text-based input medium. They are extensively deployed in customer service applications. Existing approaches to artificial conversation generation emphasize grammatical and linguistic modeling techniques. They focus on generation of discrete sentence-level utterances. These approaches perform poorly in conversa...

Tumor suppressors are so named because cancers occur in their absence, but these genes also have important functions in development, metabolism and tissue homeostasis. Here, we discuss known and potential functions of tumor suppressor genes during tissue regeneration, focusing on the evolutionarily conserved tumor suppressors pRb1, p53, Pten and Hippo. We propose that their activity is essentia...
