  • We would like to draw attention to Hidden Markov Tree Models (HMTM), which are to our knowledge still unexploited in the field of Computational Linguistics, in spite of highly successful Hidden Markov (Chain) Models. In dependency trees, the independence assumptions made by HMTM correspond to the intuition of linguistic dependency. Therefore we suggest to use HMTM and tree-modified Viterbi algorithm for tasks interpretable as labeling nodes of dependency trees.

  • The quality of phased array and synthetic aperture ultrasonic images is limited by several factors determined by the sound propagation physics and diffraction laws. Image quality is mainly determined by: Resolution, which depends on signal bandwidth (in the axial direction) and on the aperture extent (in the lateral direction); Dynamic range, which is bounded by the ratio of the main to the sidelobes level and is related to the smallest features detection capability.

  • This paper proposes a dependency parsing method that uses bilingual constraints to improve the accuracy of parsing bilingual texts (bitexts). In our method, a targetside tree fragment that corresponds to a source-side tree fragment is identified via word alignment and mapping rules that are automatically learned. Then it is verified by checking the subtree list that is collected from large scale automatically parsed data on the target side.

  • Dependency structures do not have the information of phrase categories in phrase structure grammar. Thus, dependency parsing relies heavily on the lexical information of words. This paper discusses our investigation into the effectiveness of lexicalization in dependency parsing. Specifically, by restricting the degree of lexicalization in the training phase of a parser, we examine the change in the accuracy of dependency relations. Experimental results indicate that minimal or low lexicalization is sufficient for parsing accuracy. ...

  • Choice of Stationary Phase Ideally for a reversed-phase separations, the retention factors (k) for all com- ponents in a sample should lie between 1 and 10 to achieve separation in a reasonable time. For a given stationary phase the k of a particular component can be controlled by changing the solvent composition of the mobile phase. However, the impact of eluent composition will depend on the type of sta- tionary phase and the nature of the components in the mixture.

  • The sub-series Ternary Alloy Systems of the Landolt-Börnstein New Series provides reliable and comprehensive descriptions of the materials constitution, based on critical intellectual evaluations of all data available at the time and it critically weights the different findings, also with respect to their compatibility with today’s edge binary phase diagrams. Selected are ternary systems of importance to alloy development and systems which gained in the recent years otherwise scientific interest.

  • This is the third volume in the series “Tutorial in Mathematical Biosciences”. These lectures are based on material which was presented in tutorials or developed by visitors and postdoctoral fellows of the Mathematical Biosciences Institute (MBI), at The Ohio State University. The aim of this series is to introduce graduate students and researchers with just a little background in either mathematics or biology to mathematical modeling of biological processes. The first volume was devoted to mathematical neuroscience, which was the focus of the MBI program in 2002–2003.

  • The cell cycle-dependent element (CDE) and the cell cycle genes homology region (CHR) control the transcription of genes with maximum expression in G2 phase and in mitosis. Promoters of these genes are repressed by pro-teins binding to CDE⁄CHR elements in G0 and G1 phases. Relief from repression begins in S phase and continues into G2 phase and mitosis.

  • Another aspect to take into account in assigning priority is the geographical extent of the impact, i.e. whether a particular problem, for example caused by a discharge of wastewater, has only a local impact in an area of a few hundred meters along the river or whether there is an impact in the entire river system downstream of the discharge. The likely answer depends, for example, on the size of the discharge and the retention time in the receiving water bodies, the degradability of the pollutant, and the occurrence of sensitive species in the receiving water body. In addition, the...

  • Substitution oftrans-proline at three positions in ubiquitin (residues 19, 37 and 38) produces significant context-dependent effects on protein stability (both stabilizing and destabilizing) that reflect changes to a combination of parameters including backbone flexibility, hydrophobic interactions, solvent accessibility to polar groups and intrinsic backbone conformational preferences. Kinetic analysis of thewild-type yeast protein reveals a predominant fast-folding phase which conforms to an apparent two-state folding model. ...

  • Information disposition and sanitization decisions occur throughout the system life cycle. Critical factors affecting information disposition and media sanitization are decided at the start of a system’s development. The initial system requirements should include hardware and software specifications as well as interconnections and data flow documents that will assist the system owner in identifying the types of media used in the system.

  • Mammalian G1 phase progression is regulated by G1 cyclin and cyclin-dependent kinases (cdks). Cdk4 or cdk6 is associated with D-type cyclins while cdk2 binds to cyclin E or cyclin A to become an independent and essential kinase [1,2]. Cdk3 is another putative G1 cdk, whose cyclin partners have not been identified [3]. In vitro, cdk3 is an active kinase in association with either cyclin E or cyclin A [4,5].

  • With the development of the technology and the way in which human labour is getting minimized and the comforts increasing tremendously the use of electrical energy is ever increasing.... The AC voltages generated may be single phase or 3-phase depending on the power supplied. For low power applications single phase generators are preferable. The basic principles involved in the production of emf and the constructional details of the generators are discussed below.

  • The type of deposit account to open depends on how you plan to use the account. If you will need to gain access to your money on a frequent basis, use a chequing or savings account. If you do not need to use your money for a longer period, a time deposit account may be best for you. Interest rates will vary depending on the type of deposit account opened by a consumer. This is because each type of account will have its own terms and conditions. Generally, the longer you can guarantee your funds are deposited in the bank’s account, the higher the interest...

  • Using co-immunoprecipitation combined with MS analysis, we identified the a¢ subunit of casein kinase 2 (CK2) as an interaction partner of the atypical Rio1 protein kinase in yeast. Co-purification of Rio1p with CK2 from Dcka1 or Dcka2 mutant extracts shows that Rio1p preferentially interacts with Cka2p in vitro.

  • NAD + -dependent (R)-2-hydroxyglutarate dehydrogenase (HGDH) cata-lyses the reduction of 2-oxoglutarate to (R)-2-hydroxyglutarate and belongs to the D-2-hydroxyacid NAD + -dependent dehydrogenase (D-2-hydroxyacid dehydrogenase) protein family. Its crystal structure was determined by phase combination to 1.98 A˚ resolution. Structure–function relationships obtained by the comparison of HGDH with other members of theD-2-hydroxyacid dehydrogenase family give a chemically satisfying view of the substrate stereoselectivity and catalytic requirements for the hydride trans-fer reaction.
