Ordered sets are used as a computational model for motion planning in which figures on the plane may be moved along a ray emanating from a light source. The resulting obstructions give rise to ordered sets which, in turn, are precisely ...

Amitai's pioneering works serve as a cornerstone in p. i. theory and algebraic combinatorics. Amitai's work has spanned not only these, but also real analysis, probability, number theory, Lie algebras and, especially, representation the...

A patient with a so-called ‘butterfly vertebra’ is presented. Radiography, including computed tomography, is shown. The embryology and pathogenesis of the vertebral column with respect to vertebral abnormalities are discussed, with ...

Special constraints are imposed on liquid helium transfer in space relying on the fountain effect (thermomechanical effect) for the movement of liquid He II below the lambda point. The present Paper considers thermodynamic pump system o...

New exact travelling wave solutions for the double sinh-Gordon equation and its generalized form are formally derived by using the tanh method and the variable separated ODE method. The Painlevé property v = eu is employed to support t...

An explicit formula for the solution of the discrete version of the Fisher-Wright Nike Air Max 2014 Canada selection model is given. Mathematically, the equations of this model form a system of non-linear difference equations of first o...

The paper describes polyhedral realizations of the 4-dimensional ‘finite regular skew polyhedra’ {4,6|3}, {6,4|3}, {4,8|3}, {8,4|3} in Euclidean 3-space.Also a new proof of regularity is given, stressing the fact that the automorphi...

The speckle patterns scattered from the boundary surfaces of a birefringent slice are imaged on a photographic plate. The method consists in taking account of the variations of the statistical properties of the two superimposed speckle ...

We provide a simple constructive characterization for trees with equal Cheap Air Max 2013 domination and independent domination numbers, and for trees with equal domination and total domination numbers. We also consider a general framew...

The “Reggeometry” model — universal impact parameter profile and Reggen behaviour — is applied to recent data on π+ p → π° (π+ p) at different energies and (π+p) missing masses, including Δ production. We are able, in pa...
