Preferred orientation in granitic mylonites from the Santa Rosa mylonite zone in Southern California is investigated with time-of-flight neutron diffraction. Quartz and biotite display strong preferred orientation, whereas, feldspar alignment is weak. For quartz, a c-axis maximum in the intermediate fabric direction is consistent with dynamic recrystallization. Pole figures for positive and neg...

This paper considers the famous Fermi-Pasta-Ulam chain with periodic boundary conditions and quartic nonlinearities. Due to special resonances and discrete symmetries, the Birkhoff normal form of this Hamiltonian system is completely integrable, as was shown in [16]. We study how the level sets of the integrals foliate the phase space. Our study reveals all the integrable structure in the low e...

We examine the solution of the constraints in spherically symmetric general relativity when spacetime has a flat spatial hypersurface. We demonstrate explicitly that given one flat slice, a foliation by flat slices can be consistently evolved. We show that when the sources are finite these slices do not admit singularities and we provide an explicit bound on the maximum value assumed by the ext...

The character of the boundary between tectonic units in Central Taurides and Ulukışla Basin is controversial. contact has been accepted as discordant or by different researchers. deformation data study area provide important information about Mesozoic - Cenozoic period geological developments region.

We shall describe such maximal atlas and provide it with an algebraic structure that brings along the holonomy groupoid almost for free. This will, at the same time, correct an attempt I made in [5] to ”algebraicize” some considerations of Haefliger. The content is not very original; one may say that it only synthesises insights that are more or less explicit in the work of Haefliger, Pradines,...

Corrections are given to some of the proofs of the paper above In this note, we point out and correct some errors in the proofs of the main results in the paper [1]. The main results themselves are correct as stated, but the proofs need modification. To begin, the proof of Lemma 3.3 in [1] is incorrect. Thus, h in [1, (3.12)] is the linearization of a mapping ∂C → ∂C, and so has n degrees of fr...

Anisotropy of magnetic susceptibility (AMS) and anhysteretic remanence (AAR) were used to evaluate the emplacement history Parashi stock related dyke swarm situated in NW Colombia. The average 4.5×10-2 SI, conjunction with low-coercivity components provided by isothermal thermomagnetic curves net Verwey Curie transitions, indicates that multidomain magnetite records anisotropy directions. simil...
