Intrinsically disordered proteins in molecular recognition and structural proteomics
Protein function Protein structure Protein interactions
2015/5/26
Intrinsically disordered proteins (IDPs) are abundant in nature, being more prevalent in the proteomes of eukaryotes than those of bacteria or archaea. As introduced in Chapter I, these proteins, or p...
Comment on “Phase Diagram of a Disordered Boson Hubbard Model in Two Dimensions”
Superfluid mott insulation bose glass monte carlo simulation
2014/12/20
In a recent Letter [1] (see also [2]) the authors presented numerical evidence supporting an idea of a direct transition between the superfluid (SF) and Mott insulating (MI) phases in the disordered B...
Superfluid-Insulator Transition in Commensurate Disordered Bosonic Systems: Large-Scale Worm Algorithm Simulations
Monte carlo simulation insulator dynamics
2014/12/20
We report results of large-scale Monte Carlo simulations of superfluid-insulator transitions in disordered commensurate 2D bosonic systems. In the off-diagonal disorder case, we find that the transiti...
Absence of a Direct Superfluid to Mott Insulator Transition in Disordered Bose Systems
Quantum phase transition superfluid mott insulator bosonic system inclusions
2014/12/19
We prove the absence of a direct quantum phase transition between a superfluid and a Mott insulator in a bosonic system with generic, bounded disorder. We also prove the compressibility of the system ...

Disordered phase diagram the three dimensional Bose - Hubbard model inclusions superfluids
2014/12/19
We establish the phase diagram of the disordered three-dimensional Bose-Hubbard model at unity filling which has been controversial for many years. The theorem of inclusions, proven by Pollet et al. [...

Allostery DnaK Hsp70 Intrinsic disorder Molecular chaperone Protein folding
2014/12/10
Hsp70 molecular chaperones protect proteins from aggregation, assist in their native structure formation, and regulate stress responses in the cell. A mechanistic understanding of Hsp70 function will ...

2014/9/24
Excitonic transport in static-disordered one dimensional systems is studied in the presence of thermal fluctuations that are described by the Haken–Strobl–Reineker model. For short times, non-diffusiv...
