A family of probability distributions parametrized by an open domain Λ in Rn defines the Fisher information matrix on this domain which is positive semi-definite. In information geometry the standard assumption has been that the Fisher information matrix is positive definite defining in this way a Riemannian metric on Λ. If we replace the "positive definite" assumption by "0-deformable" conditi...

We have considered a semi-infinite crack embedded in a transversely isotropic medium and studied two special cases, one, in which the axis of symmetry is normal to the crack face and the wave incidence is arbitrary and another, in which the axis lies in the crack plane normal to the edge and the incident wave vector is also normal to the edge. The problem is of interest in Non-Destructive Evalu...

We consider hard electroproduction of mesons at twist-3 level and focus our attention on helicity flip amplitudes corresponding to the production of transversely polarized mesons by transverse photons. We demonstrate that helicity-flip amplitude for the transversely polarized particles are closely related to the contributions of the matrix elements of the tensor gluon operator which can serve a...

We study the fragmentation of a transversely polarized quark into a non collinear (k⊥ 6= 0) spinless hadron and the fragmentation of an unpolarized quark into a non collinear transversely polarized spin 1/2 baryon. These nonperturbative properties are described by spin and k⊥ dependent fragmentation functions and are revealed in the observation of single spin asymmetries. Recent data on the pro...

We have constructed a state-of-the-art, high luminosity polarized proton and deuteron target and propose to measure the Sivers asymmetry for the ū and d̄ sea quarks in the nucleon for four different Bjorken xB bins in the range 0.1 < xB < 0.5, using the Drell-Yan process at SeaQuest. We will: i) perform the first measurement of the Sivers asymmetry in Drell-Yan scattering for sea quarks; ii) det...

We analyze the propagation of surface plasmons in metallic multimode waveguides that consist of alternating stripes of different metals in the transverse direction and that are homogeneous in the longitudinal direction. The purpose of structuring the waveguide in the transverse direction is to take advantage of the different attenuation and propagation constants for different metals. Here, in p...

Intrinsic transverse momentum (kT) plays an important role in the quark distribution functions ~DF’s! used to describe a polarized nucleon @1,2#. For the leading ~twist-two! part of the deep inelastic scattering cross section one already needs six DF’s to describe the quark state in a polarized nucleon. They depend on x and kT 2 , which parametrize the quark momentum in a nucleon with momentum ...

A commonly used model for a transversely anisotropic crack rock is that by Hudson (1980, 1981). This model is based on a simplified analysis of a thin circular crack, with displacement and stress conditions specified on the boundary. These papers have a second order correction in addition to the first order term in porosity/crack density. In this paper we compare the results of Hudson with thos...

By means of a microscopic theory we calculate the effect of a current flowing transverse to conducting chains on the charge-density wave (CDW) dynamics along the chains. In contrast to a recent prediction (L. Radzihovsky and J. Toner, Phys. Rev. Lett. 81, 3711 (1998)) we found that contributions from transverse flows of electron-like and hole-like quasiparticles to the force exhibited by the CD...

Mathematical expressions are derived for the far-field backscattering amplitude spectrum resulting from oblique insonification of an infinite, transversely isotropic elastic cylinder by a plane acoustic wave. The normal-mode solution is based on decoupling of the scalar potential representing the horizontally polarized shear wave from those of the compressional and vertically polarized waves. T...
