  • Under explicit diophantine conditions on (α, β) ∈ R2 , we prove that the local two-point correlations of the sequence given by the values (m − α)2 + (n−β)2 , with (m, n) ∈ Z2 , are those of a Poisson process. This partly confirms a conjecture of Berry and Tabor [2] on spectral statistics of quantized integrable systems, and also establishes a particular case of the quantitative version of the Oppenheim conjecture for inhomogeneous quadratic forms of signature (2,2). The proof uses theta sums and Ratner’s classification of measures invariant under unipotent flows. ...

  • In this paper, we present a block-based model for statistical machine translation. A block is a pair of phrases which are translations of each other. For example, Fig. 1 shows an Arabic-English translation example that uses blocks. During decoding, we view translation as a block segmentation process, where the input sentence is segmented from left to right and the target sentence is generated from bottom to top, one block at a time. A monotone block sequence is generated except for the possibility to swap a pair of neighbor blocks.

  • In this paper, we exploit non-local features as an estimate of long-distance dependencies to improve performance on the statistical spoken language understanding (SLU) problem. The statistical natural language parsers trained on text perform unreliably to encode non-local information on spoken language. An alternative method we propose is to use trigger pairs that are automatically extracted by a feature induction algorithm. We describe a light version of the inducer in which a simple modification is efficient and successful. ...

  • The book includes 17 chapters written by noted scientists and young researchers and dealing with various aspects of superconductivity, both theoretical and experimental. The authors tried to demonstrate their original vision and give an insight into the examined problems. A balance between theory and experiment was preserved at least from the formal viewpoint (9 and 8, respectively). The readers should be warned that many of the problems studied here are far from being solved and are treated on the basis of competing viewpoints.

  • We completely classify diffeomorphism covariant local nets of von Neumann algebras on the circle with central charge c less than 1. The irreducible ones are in bijective correspondence with the pairs of A-D2n-E6,8 Dynkin diagrams such that the difference of their Coxeter numbers is equal to 1. We first identify the nets generated by irreducible representations of the Virasoro algebra for c

  • This is particularly relevant because estimated differences between SRI and conventional funds may not be due to the socially responsible investing per se, but to differences between the companies that manage SRI funds and those that manage conventional funds. Finally, we improve upon the matched-pair analysis employed in several prior studies by using the matching estimator methodology of Abadie and Imbens (2006).

  • ADC LSA-PLUS® connection systems include connection, disconnection and switching modules for eight or ten pairs, all featuring the patented LSA-PLUS interconnection displacement connection (IDC) technology. LSA-PLUS connection systems support connection, line splitting, switching and earthing of connections in telecommunication and data networks. The contact is resistant to climatic and other environmental problems. Technical contact security results in the formation of a gas-tight connection with very low transmission resistance.

  • This article concludes the comprehensive study started in [Sz5], where the first nontrivial isospectral pairs of metrics are constructed on balls and spheres. These investigations incorporate four different cases since these balls and spheres are considered both on 2-step nilpotent Lie groups and on their solvable extensions. In [Sz5] the considerations are completely concluded in the ball-case and in the nilpotent-case. The other cases were mostly outlined. In this paper the isospectrality theorems are completely established on spheres. ...

  • Kinetic experiments with a substrate series of phenylacetyl-arylamides reveal that at least one polar group in the amine moiety is required for the proper orientation of the substrate in the large nucleophile-binding subsite of penicillin acylase ofEscherichia coli. Quantum mechanical molecular model-ling of enzyme–substrate interactions in the enzyme active site shows that in the case of substrates lacking local sym-metry, the productive binding implies two nonsymmetrical arrangements with respect to the two positively charged guanidinium residues of ArgA145 and ArgB263....

  • The Heart Truth warns women about heart disease and encourages them to take action against its risk factors. The message is paired with an arresting image—the Red Dress—the national symbol for women and heart disease awareness. The symbol links a woman’s focus on her “outer self” to the need to also focus on her “inner self,” especially her heart health. The Red Dress is a visual “red alert” to convey the message that “Heart Disease Doesn’t Care What You Wear—It’s the #1 Killer of Women.”...

  • Ethernet is a local area network technology that transmits information between computers at speeds of 10 and 100 Mbps. Ethernet is a local area network (LAN) that employs a bus topology (all of the workstations are connected to a single physical medium). It is a broadcast network, which means that all of the workstations on the network receive all transmissions. Ethernet media varieties include the original thick coaxial system, as well as thin coaxial, twisted-pair, and fiber optic systems. ...
