Entity Linking is to link a name string from plain-text documents to the corresponding entry in given knowledge base. In this paper we demonstrate our entity linking system for TAC KBP 2011 Track. Our system implements pairwise and listwise learning to rank methods to create a ranking list of candidates with several kinds of features, including context similarity, term frequency, key entity ext...

Photosystem I from the cyanobacterium Synechocystis sp. PCC 6803 was examined using the chemical cross-linkers glutaraldehyde and N-ethyl-1-3-[3-(dimethylamino)propyl]carbodiimide to investigate the organization of the polypeptide subunits. Thylakoid membranes and photosystem I, which was isolated by Triton X-100 fractionation, were treated with cross-linking reagents and were resolved using a ...

Objective: to present corneal collagen corsslinking techniques. Corneal collagen cross-linking (CXL) is a procedure used to slow down or arrest the progression of keratoconus in order to avoid or, at least delay the necessity of keratoplasty. CXL means photopolimerisation of the stromal fibrillar tissue, in order to increase their stiffness and resistance to the corneal ectasia. CXL is a proces...

PURPOSE Extracellular matrix metalloproteinases (MMPs) are thought to play a crucial role in corneal degradation associated with the pathological progression of keratoconus. Currently, corneal cross-linking by riboflavin and ultraviolet A (RFUVA) has received significant attention for treatment of keratoconus. However, the extent to which MMPs digest cross-linked collagen and small leucine-rich...

Cyclodisone is an active alkylating antitumor agent that is being considered for Phase 1 clinical trials in humans and is currently undergoing toxicological evaluation. Cyclodisone was found to be more toxic to human colon carcinoma cells of the Mer- phenotype (BE) than cells of the Mer+ phenotype (HT-29). DNA interstrand cross-links were observed in the sensitive cell line but only at concentr...

PURPOSE To evaluate the biomechanical changes occurring after LASIK flap creation and rapid corneal cross-linking (CXL) measured with Brillouin light microscopy. METHODS Porcine eyes (n = 11) were evaluated by Brillouin light microscopy sequentially in the following order: virgin state, after LASIK flap creation, and after rapid CXL. Each eye served as its own control. Depth profile of the Br...

Abstract The spread of microbes which cause infectious diseases are great concern on human health. Therefore, a water-soluble cross-linked polymer based polyvinyl alcohol was synthesized via an economical, facile, and aqueous-based approach. resultant characterized by different techniques such as FTIR, 1 H NMR, 13 C TGA, DSC. IR spectrum has been recorded in the range 400–4000 cm −1 . From ther...
