Critical Dynamics of Contact Line Depinning [PDF]

open access: yesMRS Proceedings, 1994
ABSTRACTThe depinning of a contact line is studied as a dynamical critical phenomenon by a functional renormalization group technique. In D = 2 - ∈ “line” dimensions, the roughness exponent is ζ = ∈/3 to all orders in perturbation theory. Thus, ζ = 1/3 for the contact line, equal to the Imry-Ma estimate for equilibrium roughness. The dynamical exponent

Applying Markowitz's Critical Line Algorithm [PDF]

open access: yes, 2006
We provide a Matlab quadratic optimization tool based onMarkowitz's critical line algorithm that significantly outperforms standard software packages and a recently developed operations research algorithm. As an illustration: For a 2000 asset universe our method needs less than a second to compute the whole frontier whereas the quickest competitor ...

Critical convective-type equations on a half-line [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
We are interested in the global existence and large-time behavior of solutions to the initial-boundary value problem for critical convective-type dissipative equations ut+ℕ(u,ux)+(an∂xn+am∂xm)u=0, (x,t)∈ℝ+×ℝ+, u(x,0)=u0(x), x∈ℝ+, ∂xj−1u(0,t)=0 for j=1,…

The Critical Group of a Line Graph [PDF]

open access: yesAnnals of Combinatorics, 2012
The critical group of a graph is a finite abelian group whose order is the number of spanning forests of the graph. This paper provides three basic structural results on the critical group of a line graph. The first deals with connected graphs containing no cut-edge. Here the number of independent cycles in the graph, which is known to bound the number

Classifying Potts critical lines [PDF]

open access: yesPhysical Review E, 2017
We use scale invariant scattering theory to exactly determine the lines of renormalization group fixed points invariant under the permutational symmetry $S_q$ in two dimensions, and show how one of these scattering solutions describes the ferromagnetic and square lattice antiferromagnetic critical lines of the $q$-state Potts model.

A Note on the Critical Group of a Line Graph [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2011
This note answers a question posed by Levine. The main result shows that under certain circumstances a critical group of a directed graph is the quotient of a critical group of its directed line graph.

The experimental line in fiction [PDF]

open access: yes, 2012
This chapter considers what J. M. Coetzee has called ‘the experimental line’ within the works of black and white writers in English and Afrikaans, showing how, during the apartheid years, its playfulness and experimentalism was often passed over in ...

The puzzle of spontaneous versus traumatic intracranial hemorrhages

open access: yesEgyptian Journal of Neurosurgery, 2020
Intracerebral hemorrhage is hemorrhage occurring in the brain that can occur because of immediate trauma or structural disease process. The age-standardized mortality rate is decreasing worldwide especially in the past 20 years, but the number of cases ...
