Avalanches and clusters in planar crack front propagation [PDF]
, 2010 We study avalanches in a model for a planar crack propagating in a disordered medium. Due to long-range interactions, avalanches are formed by a set of spatially disconnected local clusters, the sizes of which are distributed according to a power law ...

Extremes of Error Exponents [PDF]
IEEE Transactions on Information Theory, 2013 This paper determines the range of feasible values of standard error exponents for binary-input memoryless symmetric channels of fixed capacity $C$ and shows that extremes are attained by the binary symmetric and the binary erasure channel. The proof technique also provides analogous extremes for other quantities related to Gallager's $E_0$ function ...

Crumpling wires in two dimensions
, 2008 An energy-minimal simulation is proposed to study the patterns and mechanical properties of elastically crumpled wires in two dimensions. We varied the bending rigidity and stretching modulus to measure the energy allocation, size-mass exponent, and the ...

Dynamical Critical Exponent for Two-Species Totally Asymmetric Diffusion on a Ring [PDF]
, 2010 We present a study of the two species totally asymmetric diffusion model using the Bethe ansatz. The Hamiltonian has $U_q(SU(3))$ symmetry. We derive the nested Bethe ansatz equations and obtain the dynamical critical exponent from the finite-size ...

Generalized Exponents and Forms [PDF]
Journal of Algebraic Combinatorics, 2005 Let \(V=\mathbb{C}^l\) or \(\mathbb{R}^l\) be a complex or real vector space. A reflection is an element of \(\text{GL}(V)\) whose fixed point set is a hyperplane in \(V\). Let \(G\) be a reflection group, i.e., a finite subgroup of \(\text{GL}(V)\) generated by reflections. We assume all \(G\)-modules are \(\mathbb{C} G\)-modules. For any \(G\)-module

On inverses of APN exponents [PDF]
2012 IEEE International Symposium on Information Theory Proceedings, 2012 In this extended abstract we present results on the inverses modulo 2n − 1 of the known APN exponents. In particular, we describe explicitly the inverses of the Welch and Dobbertin exponents and give the main ideas of their proofs. Further, we observe that the inverse of the Dobbertin exponent defines an APN function on F2n of algebraic degree n+3 ...

Recent trends in revision knee arthroplasty in Germany
Scientific Reports, 2021 We aimed to answer the following questions: (1) How did numbers of revision knee arthroplasty procedures develop in Germany over the last decade compared to primary TKA? (2) How high was the percentage of septic interventions in knee prosthesis revisions?
