Stone circles: form and soil kinematics.
Distinct surface patterns are ubiquitous and diverse in soils of polar and alpine regions, where the ground temperature oscillates about 0 degrees C. They constitute some of the most striking examples of clearly visible, abiotic self-organization in nature. This paper outlines the interplay of frost-related physical processes that produce these patterns spontaneously and presents unique data do...
متن کاملA Note on Perturbative and Nonperturbative Instabilities of Twisted Circles
In this short note we compare the endpoint of tachyon condensation of twisted circles with the endpoint of nonpertubative brane nucleation in the Kaluza-Klein Melvin spacetime. July 2002 † [email protected] * Address after August 1st, 2002
متن کاملSampling on Concentric Circles
Two forms of a sampling theorem for concentric circles are established for a bandlimited two-dimensional (2-D) function. The location of the samples is prescribed either on equidistant circles or on the roots of the Bessel function J0( ). Both methods give comparable results, however, the number of samples required for their numerical evaluation is significantly less for the root-sampling formu...
متن کاملLattice Points on Circles
We prove that the lattice points on the circles x2 + y2 = n are well distributed for most circles containing lattice points.
متن کاملTesting Analyticity on Circles
Globevnik [G] answered the question in the affirmative for rotation invariant families. Agranovsky and Globevnik [AG] resolved the question for families of circles when f is a rational or real-analytic functions of two real variables. Ehrenpreis [E2] independently found solution for the circles of constant radii with centers on a line and real-analytic functions. In [T] we obtain the affirmativ...
