We analyse the security of the cryptographic hash function LAKE-256 proposed at FSE 2008 by Aumasson, Meier and Phan. By exploiting non-injectivity of some of the building primitives of LAKE, we show three different collision and near-collision attacks on the compression function. The first attack uses differences in the chaining values and the block counter and finds collisions with complexity...

The study of distribution channels is an important line of inquiry in several fields. In marketing, managing conflict and coordination in channels is studied in behavioral and managerial research (see Gaski 1984 for a review), game theoretic modeling (e.g., Jeuland and Shugan 1983), and empirical research (e.g., Ailawadi 2001). Related work in management information systems and operations manag...

The flow of viscoelastic fluids between parallel plates under the combined influence of electro-osmotic and pressure gradient forcings with asymmetric boundary conditions, by considering different zeta potentials at the walls, is investigated. The fluids are z–z symmetric electrolytes. The analytic solutions of the electrical potential, velocity distributions and streaming potential are based o...

We have implemented the log-conformation method for two-dimensional viscoelastic flow in COMSOL, a commercial high-level finite element package. The code is verified for an Oldroyd-B fluid flowing past a confined cylinder. We are also able to describe the well-known bistability of the viscoelastic flow in a crossslot geometry for a FENE-CR fluid, and we describe the changes required for perform...

In the title compound, [Cu(2)(C(10)H(8)N(2))(2)(C(58)H(52)N(2)P(4))](BF(4))(2), the dinuclear cation lies on an inversion centre. The Cu(I) atom is coordinated by two N atoms from a 2,2'-bipyridine ligand and two P atoms from an N,N,N',N'-tetra-kis-[(diphenyl-phos-phan-yl)meth-yl]benzene-1,4-diamine ligand in a distorted tetra-hedral geometry. In the crystal, inter-molecular C-H⋯F hydrogen bond...

In this paper, a strong version of Wald’s Axiom of excess demand functions Z : P ⊂ IR >0 → IR n is introduced, namely “there exists σ > 0 such that p, q ∈ P, qZ(p) − δ ≤ 0, |δ| < σ, and Z(q) 6= Z(p) imply pZ(q) + δ > 0”. We show that Z satisfies the strong version of Wald’s Axiom iff −Z is a s-quasimonotone function introduced in An (2006). Consequently, an excess demand function Z satisfies th...

We derive rigorous three-point upper and lower bounds on the eeective bulk and shear moduli of a two-phase material composed of equisized spheres randomly distributed throughout a matrix. Our approach is analogous to previously derived three-point cluster bounds on the eeective conductivity of suspensions of spheres. Our bounds on the eeective elastic moduli are then compared to other known thr...

Field Editor: P. Phan When and why one type of entrepreneur (franchisor) attracts to its ventures another type of entrepreneur (franchisees) instead of passive investors is a central concern in entrepreneurship literature. Based on the informativeness principle of the principal–agent model, we claim that franchisees are not such an expensive financial tool as has been argued in the literature b...
