Constructing Structure Ensembles of Intrinsically Disordered Proteins from Chemical Shift Data
Constructing Structure Ensembles Intrinsically Disordered Proteins Chemical Shift Data
2016/1/22
Modeling the structural ensemble of intrinsically disordered proteins (IDPs),which lack fixed structures, is essential in understanding their cellular functions and re-vealingtheirregulationmechanisms...
One-step generation of multipartite entanglement among nitrogen-vacancy center ensembles
One-step generation multipartite entanglement nitrogen-vacancy center ensembles
2016/1/22
We describe a one-step, deterministic and scalable scheme for creating macroscopic arbitrary entangled coherent states (ECSs) of separate nitrogen-vacancy center ensembles (NVEs) that couple to a supe...
Attainment of the multiple quantum Chernoff bound for certain ensembles of mixed states
multiple quantum Chernoff bound certain ensembles mixed states
2015/8/25
We consider the problem of detecting the true quantum state among r possible ones, based onmeasurements performed on n of copies of a finite dimensional quantum system. It is known that the exponent f...
The asymptotic error floor of LDPC ensembles under BP decoding
Binary no memory random elements the noise
2015/8/21
We consider communication over binary memoryless symmetric channels using random elements from irregular low density parity check code (LDPC) ensembles, and belief propagation (BP) decoding. Under the...
FINITE-LENGTH SCALING FOR ITERATIVELY DECODED LDPC ENSEMBLES

2015/8/21
In this paper we investigate the behavior of iteratively decoded low-density paritycheck codes over the binary erasure channel in the so-called “waterfall region.” We show that the performance curves ...

Statistics turbulent coherent structures mechanical model the model of two-dimensional fluid motion
2014/12/29
We consider a general class of statistical mechanical models of coherent structures in turbulence, which includes models of two-dimensional fluid motion, quasi-geostrophic flows, and dispersive waves....
Nonequivalent statistical equilibrium ensembles and refined stability theorems for most probable flows
Two-dimensional correlation structure of equilibrium model the model of energy balance ratio model water resources
2014/12/29
Statistical equilibrium models of coherent structures in two-dimensional and barotropic quasi-geostrophic turbulence are formulated using canonical and microcanonical ensembles, and the equivalence or...
An introduction to the thermodynamic and macrostate levels of nonequivalent ensembles
The contour the thermodynamics macro status the equivalent amount of collection
2014/12/29
This short paper presents a nontechnical introduction to the problem of nonequivalent microcanonical and canonical ensembles. Both the thermodynamic and the macrostate levels of definition of nonequiv...
Thermodynamic versus statistical nonequivalence of ensembles for the mean-field Blume-Emery-Griffiths model
Not equivalent statistical mechanics testing model not equivalent common thermodynamics
2014/12/29
We illustrate a novel characterization of nonequivalent statistical mechanical ensembles using the mean-field Blume–Emery–Griffiths (BEG) model as a test model. The novel characterization takes effect...
Generalized canonical ensembles and ensemble equivalence
Boltzmann continuous function generalized canonical ensemble and physics
2014/12/25
This paper is a companion piece to our previous work [J. Stat. Phys. 119, 1283 (2005)], which introduced a generalized canonical ensemble obtained by multiplying the usual Boltzmann weight factor e...
Nonconcave entropies from generalized canonical ensembles
Microcanonical ensemble entropy the curies - Weiss - Potts spin model model
2014/12/25
It is well known that the entropy of the microcanonical ensemble cannot be calculated as the Legendre transform of the canonical free energy when the entropy is nonconcave. To circumvent this problem,...

Reduce model Hamiltonian dynamics system model reduction space
2014/12/24
A new method of deriving reduced models of Hamiltonian dynamical systems is developed using techniques from optimization and statistical estimation. Given a set of resolved variables that define a mod...

Quantum tunneling magnetic molecules monte carlo simulation tunnel lorentz line shape crystal
2014/12/20
The nuclear spin-mediated quantum relaxation of ensembles of tunneling magnetic molecules causes a “hole” to appear in the distribution of internal fields in the system. The form of this hole and its ...

Bias magnetization the molecular rotation the monte carlo simulation magnetization relaxation lattice
2014/12/20
Our work has argued for a particular scaling form governing the distribution M(ξ,t) of magnetization over bias ξ, for a system of dipolar-interacting molecular spins. This form, which was found in Mon...
