We present two methods suitable for controlling the translational degrees of freedom of a system when evaluating directly the free energy difference between the liquid and the solid phases by thermodynamic integration along a reversible path connecting these two phases. Such a constraint is crucial for an accurate prediction of the melting point by means of simulation. In one of the methods, th...

A coupled transcription-translation system was isolated from A. tumefaciens. Expression of plasmids pBR322 and pKT212 from E.coli, cloned fragments of Ti plasmid (plasmids pSS155 and pSS156) and Ti plasmid derivatives pAL2802, pAL2811, pAL2821 and pAL2832 was analysed in an A. tumefaciens cell-free system and compared with their expression in an E.coli cell-free system. New proteins of 41K and ...

We present the Carnegie Mellon University Stat-XFER group submission to the WMT 2011 shared translation task. We built a hybrid syntactic MT system for French–English using the Joshua decoder and an automatically acquired SCFG. New work for this year includes training data selection and grammar filtering. Expanded training data selection significantly increased translation scores and lowered OO...

We present a procedure to compute the absolute free energy of solid phases by Monte Carlo simulation. The method is based on the so-called "Einstein-crystal" method of Frenkel and Ladd [J. Chem. Phys. 81, 3188 (1984)]. The new technique is more general and simplifies the calculation for systems with hard core interactions. In addition, the reference Einstein crystal is built up to fulfill trans...

Syntactic word reordering is essential for translations across different grammar structures between syntactically distant languagepairs. In this paper, we propose to embed local and non-local word reordering decisions in a synchronous context free grammar, and leverages the grammar in a chartbased decoder. Local word-reordering is effectively encoded in Hiero-like rules; whereas non-local word-...
