  • We propose Bilingual Tree Kernels (BTKs) to capture the structural similarities across a pair of syntactic translational equivalences and apply BTKs to sub-tree alignment along with some plain features. Our study reveals that the structural features embedded in a bilingual parse tree pair are very effective for sub-tree alignment and the bilingual tree kernels can well capture such features.

  • This paper proposes a novel composite kernel for relation extraction. The composite kernel consists of two individual kernels: an entity kernel that allows for entity-related features and a convolution parse tree kernel that models syntactic information of relation examples. The motivation of our method is to fully utilize the nice properties of kernel methods to explore diverse knowledge for relation extraction.

  • Sentence fluency is an important component of overall text readability but few studies in natural language processing have sought to understand the factors that define it. We report the results of an initial study into the predictive power of surface syntactic statistics for the task; we use fluency assessments done for the purpose of evaluating machine translation. We find that these features are weakly but significantly correlated with fluency. Machine and human translations can be distinguished with accuracy over 80%.

  • In this study, structural features of Tricholoma matsutake polysaccharide (TMP-A) were investigated by a combination of infrared (IR) spectra, gas chromatography–mass spectrometry (GC–MS), nuclear magnetic resonance (NMR) spectroscopy. The results indicated that TMP-A had a backbone of 1,4-- d-glucopyranose residue which branches at O-6 based on the experimental results. The branches were mainly composed of an (1→3)--d-galactopyranose residue, and terminated with -d-xylopyranose residue.

  • Laccases are copper-containing enzymes used in various applications, such as textile bleaching. Several crystal structures of laccases from fungi and bacteria are available, but ascomycete types of fungal laccases (asco-lac-cases) have been rather unexplored, and to date only the crystal structure ofMelanocarpus albomyceslaccase (MaL) has been published.

  • Group II introns are both catalytic RNAs and mobile retroelements that move through a process catalyzed by a RNP complex consisting of an intron-encoded protein and the spliced intron lariat RNA. Group II intron-encoded proteins are multifunctional and contain an N-terminal reverse transcriptase domain, followed by a putative RNA-binding domain (domain X) associated with RNA splicing or maturase activity and a C-terminal DNA binding⁄DNA endonuclease region.

  • Syntactic knowledge is important for pronoun resolution. Traditionally, the syntactic information for pronoun resolution is represented in terms of features that have to be selected and defined heuristically. In the paper, we propose a kernel-based method that can automatically mine the syntactic information from the parse trees for pronoun resolution. Specifically, we utilize the parse trees directly as a structured feature and apply kernel functions to this feature, as well as other normal features, to learn the resolution classifier.

  • In human monocyte-derived macrophages, the MCPIPgene (monocyte chemoattractant protein-induced protein) is strongly activated by inter-leukin-1b(IL-1b). Using bioinformatics, a PIN domain was identified, span-ning amino acids 130-280; such domains are known to possess structural features of RNases. Recently, RNase properties of MCPIP were confirmed on transcripts coding for interleukins IL-6 and IL-12p40.

  • If natural language had been designed by a logician, idioms would not exist. They are a feature of discourse that frustrates any simple logical account of how the meanings of utterances depend on the meanings of their parts and on the syntactic relation among those parts. Idioms are transparent to native speakers, but a course of perplexity to those who are acquiring a second language. If someone tells me that Mrs. Thatcher has become the Queen of Scotland, I am likely to say: "That's a tall story.

  • The tension structures discussed in this book are predominantly roofing forms created from pre-stressed cable nets, cable trusses, and continuous membranes (fabric structures). A unique feature in their design is form-finding an interactive process of defining the shape of a structure under tension. The book discusses the role of stable minimal surfaces (minimum energy forms occurring in natural objects, such as soap films) in finding optimal shapes of membrane and cable structures.

  • The Sixth Edition of Dr. Haines's best-selling neuroanatomy atlas features a stronger clinical emphasis, with significantly expanded clinical information and correlations. More than 110 new images--including MRI, CT, MR angiography, color line drawings, and brain specimens--highlight anatomical-clinical correlations. Internal spinal cord and brainstem morphology are presented in a new format that shows images in both anatomical and clinical orientations, correlating this anatomy exactly with how the brain and its functional systems are viewed in the clinical setting.

  • This work develops and defends a structural view of the nature of mathematics, which is used to explain a number of striking features of mathematics that have puzzled philosophers for centuries. It rejects the most widely held philosophical view of mathematics (Platonism), according to which mathematics is a science dealing with mathematical objects such as sets and numbers—objects which are believed not to exist in the physical world.

  • A clear understanding of rock stress and its effect on permeability is important in a coupled simulation where fluid production causes a significant increase in the effective stress within a reservoir. Changing the in-situ rock stress state can alter the reservoir properties. As a result, porosity and permeability could be affected due to the rearrangement of rock particles and the redistribution of sensitive pore structures. It is known that permeability is more sensitive to stress changes than porosity.
