A universal constitutive model for the interfacial layer between a polymer melt and a solid wall [PDF]
In a preceeding report we derived the evolution equation for the bond vector probability distribution function (BVPDF) of tethered molecules. It describes the behavior of polymer molecules attached to a solid wall interacting with an adjacent flowing ...

Development of three dimensional constitutive theories based on lower dimensional experimental data [PDF]
Most three dimensional constitutive relations that have been developed to describe the behavior of bodies are correlated against one dimensional and two dimensional experiments.

Global Solution to the Three-Dimensional Incompressible Flow of Liquid Crystals [PDF]
The equations for the three-dimensional incompressible flow of liquid crystals are considered in a smooth bounded domain. The existence and uniqueness of the global strong solution with small initial data are established.

Calculation of β-decay rates in a relativistic model with momentum-dependent self-energies [PDF]
The relativistic proton-neutron quasiparticle random phase approximation (PN-RQRPA) is applied in the calculation of β-decay half-lives of neutron-rich nuclei in the Z≈28 and Z≈50 regions.

Existence, a priori and a posteriori error estimates for a nonlinear three-field problem arising from Oldroyd-B viscoelastic flows [PDF]
In this paper, a nonlinear problem corresponding to a simplified Oldroyd-B model without convective terms is considered. Assuming the domain to be a convex polygon, existence of a solution is proved for small relaxation times.

We present a new rheological model depending on a real parameter $\nu \in [0,1]$ that reduces to the Maxwell body for $\nu=0$ and to the Becker body for $\nu=1$.

A generalization of the Lomnitz logarithmic creep law via Hadamard fractional calculus
We present a new approach based on linear integro-differential operators with logarithmic kernel related to the Hadamard fractional calculus in order to generalize, by a parameter $\nu \in (0,1]$, the logarithmic creep law known in rheology as Lomnitz ...

Strong stability of 2D viscoelastic Poiseuille-type flows [PDF]
We investigate Lp stability issues of small viscoelastic Poiseuilletype ows in two dimensions stemming from a model considered in Fang- Hua Lin, Chun Liu, and Ping Zhang (2005).

Elastic director vibrations in nematic liquid crystals [PDF]
Recently Biscari, DiCarlo and Turzi [Anisotropic wave propagation in nematic liquid crystals, Soft Matter 10, 8296-8307.] proposed a theory for nematoacustics which models nematic liquid crystals as nematic elastomers with molecular relaxation.
