Ensembl 2004

E. Birney
2004 Nucleic Acids Research  
The Ensembl (http://www.ensembl.org/) database project provides a bioinformatics framework to organize biology around the sequences of large genomes.  ...  With a total of nine genome sequences available from Ensembl and more genomes to follow, recent developments have focused mainly on closer integration between genomes and external data.  ...  The Ensembl project is funded principally by the Wellcome Trust with additional funding from EMBL and NIH-NIAID.  ...

In the present article the feasibility of teleportation is examined on the basis of the rigorous ensemble interpretation of quantum mechanics (not to be confused with a mere treatment of noisy EPR pairs  ...  on • ensembles.  ...  The ensemble {{A i },{B i }} consisting of the two sub-ensembles is represented, say, by the statistical operator ρ 4 (see eq. 4) which means that we consider the ensemble in a pure state.  ...

Holography and the Canonical Ensemble of Fermionic Strings [article]

Shyamoli Chaudhuri
2005 arXiv   pre-print
We show that the canonical ensemble in any of the six supersymmetric string theories, type IIA and IIB, type IB and type I', or heterotic E_8 x E_8 and Spin(32)/Z_2, exhibits a strong version of holography  ...  We show that, in the presence of Dbranes, and a consequent Yang-Mills gauge sector, the thermal ensemble of type II strings is infrared stable, with neither tachyons nor massless scalar tadpoles.  ...  The thermodynamics of an ensemble of strings is not the same as that of an ensemble of infinitely many free particle species with Planck scale masses.  ...

Spacing distributions in random matrix ensembles [article]

P.J. Forrester
2004 arXiv   pre-print
In the N → ∞ scaling limit these ensembles correspond with the bulk of the ensembles OE N (w 1 ), UE N (w 2 ) and SE N (w 4 ) respectively.  ...  We thus seek the theoretical determination of p(n; s) for matrix ensembles.  ...

Graded persisting activity of heterogeneous neuron ensembles subject to white noises [article]

Hideo Hasegawa
2004 arXiv   pre-print
It has been shown, however, that the graded persisting activity of ensemble neurons becomes much robust to the distractions by the pooling (ensemble) effect.  ...  When the coupling is introduced, the synchronization of firings in ensemble neurons is enhanced, which is beneficial to firings of target neurons.  ...  Nevertheless, the firing rate averaged over the ensemble is not so different from that of the homogeneous ensemble shown in Fig. 1(d) .  ...
