Stabilizing helicity of polypeptide in aqueous urea: Dipole orientation or hydrogen bonding?
Luis A. Baptista, Yani Zhao, Kurt Kremer +2
Urea denatures proteins due to its strong tendency to dehydrate the first solvation shell via urea-residue preferential binding. However, even after extensive experimental and comp…
Proline isomerization regulates the phase behavior of elastin-like polypeptides in water
Yani Zhao, Kurt Kremer
Responsiveness of polypeptides and polymers in aqueous solution plays an important role in biomedical applications and in designing advanced functional materials. Elastin-like poly…
Why Do Elastin-Like Polypeptides Possibly Have Different Solvation Behaviors in Water-Ethanol and Water-Urea Mixtures?
Yani Zhao, Manjesh K. Singh, Kurt Kremer +2
The solvent quality determines the collapsed or the expanded state of a polymer. For example, a polymer dissolved in a poor solvent collapses, whereas in a good solvent it opens up…
Structural entanglements in protein complexes
Yani Zhao, Mateusz Chwastyk, Marek Cieplak
We consider multi-chain protein native structures and propose a criterion that determines whether two chains in the system are entangled or not. The criterion is based on the behav…
Structural changes in barley protein LTP1 isoforms at air-water interfaces
Yani Zhao, Marek Cieplak
We use a coarse-grained model to study the conformational changes in two barley proteins, LTP1 and its ligand adduct isoform LTP1b, that result from their adsorption to the air-wat…
Topological transformations in proteins: effects of heating and proximity of an interface
Yani Zhao, Mateusz Chwastyk, Marek Cieplak
Using a structure-based coarse-grained model of proteins, we study the mechanism of unfolding of knotted proteins through heating. We find that the dominant mechanisms of unfolding…
The topological effect on the Mechanical properties of polymer knots
Yani Zhao, Franco Ferrari
The mechanical properties of polymer knots under stretching in a bad or good solvent are investigated by applying a given force to a point of the knot while keeping another poi…
A Topological Field Theory for the triple Milnor linking coefficient
Franco Ferrari, Marcin R. Piatek, Yani Zhao
The subject of this work is a three-dimensional topological field theory with a non-semisimple group of gauge symmetry with observables consisting in the holonomies of connections…
On a field theoretical model of polymeric plats and some of its consequences
Franco Ferrari, Jarosław Paturej, Marcin Piątek +1
The field theory approach to the statistical mechanics of a system of N polymer rings linked together is generalized to the case of links that have a fixed number of maxima an…
Ring polymers with topological constraints
Yani Zhao, Franco Ferrari
In the first part of this work a summary is provided of some recent experiments and theoretical results which are relevant in the research of systems of polymer rings in nontrivial…
Monte Carlo Computation of the Vassiliev knot invariant of degree 2 in the integral representation
Franco Ferrari, Yani Zhao
In mathematics there is a wide class of knot invariants that may be expressed in the form of multiple line integrals computed along the trajectory C describing the spatial conforma…
A study of polymer knots using a simple knot invariant written consisting of multiple contour integrals
Yani Zhao, Franco Ferrari
In this work the thermodynamic properties of short polymer knots (up to 120 segments) defined on a simple cubic lattice are studied with the help of the Wang-Landau Monte Carlo alg…
A numerical technique for preserving the topology of polymer knots: The case of short-range attractive interactions
Yani Zhao, Franco Ferrari
The statistical mechanics of single polymer knots is studied using Monte Carlo simulations. The polymers are considered on a cubic lattice and their conformations are randomly chan…
Topological effects in the thermal properties of knotted polymer rings
Yani Zhao, Franco Ferrari
The topological effects on the thermal properties of several knot configurations are investigated using Monte Carlo simulations. In order to check if the topology of the knots is p…
Hot-electron Effect in A Cylindrical Nanoshell
Ya-Ni Zhao, Lin Zhang, Shi-Xian Qu +1
A general expression for calculating the thermal power transferring from 3-dimensional electron to any D-dimensional phonon subsystem is derived in this paper. Electron-phonon coup…
Influence of the Surface Structure and Vibration Mode on the Resistivity of Cu Films
Ya-Ni Zhao, Shi-Xian Qu, Ke Xia
The influence of the surface structure and vibration mode on the resistivity of Cu films and the corresponding size effect are investigated. The temperature dependent conductivitie…
