An understanding of phase singularities of correlation functions is important in optical coherence theory and imaging science, but to date such singularities have only been theoretically studied in a single transverse plane, at most. In this Letter we evaluate the complete structure of a correlation singularity of a partially coherent Laguerre-Gauss beam, describing it in both the transverse an...

The aim of this study was to assess hip-knee and knee-ankle coupling coordination of skilled and unskilled in football kicks. A modified vector coding technique was used to evaluate coupling coordination. Cross-correlation was used to assess the similarity between the groups. In the sagittal and transverse planes, hip-knee coordination presented similar patterns for both groups. However, the kn...

We have constructed, analytically and numerically, a new class of self-consistent 6-D phase space stationary distributions. Stationary distributions allow us to study the halo development mechanism without being obscured by beam redistribution and its effect on halo formation. The beam is then mismatched longitudinally and/or transversely, and we explore the formation of longitudinal and transv...

Non-separable superpositions of polarization and spatial mode of a single photon produce a state that has a polarization that depends on the transverse position, and contains all states of polarization represented on the Poincaré sphere. We have done measurements of the space-dependent state of polarization of single photons prepared in distinct 2×2 (qubit-qubit) and 2×3 (qubit-qutrit) non-sepa...

The dynamics of low-x partons in the transverse plane of a high-energy nuclear collision is classical, and therefore admits a fully non–perturbative numerical treatment. We report results of a recent study estimating the initial energy density in the central region of a collision. Preliminary estimates of the number of gluons per unit rapidity, and the initial transverse momentum distribution o...

Here, the dynamic stability characteristics of simply supported laminated composite skew plates subjected to a periodic in-plane load are investigated using the finite element approach. The formulation includes the effects of transverse shear deformation, in-plane and rotary inertia. The boundaries of the instability regions are obtained using the Bolotin’s method and are represented in the non...

PURPOSE To describe the MR characteristics that can distinguish idiopathic transverse myelitis from other intramedullary lesions. METHODS A total of 32 initial and follow-up MR studies in 17 patients with clinically proved transverse myelitis were reviewed retrospectively. The location, size, pattern, and segmental length of areas of hyperintensity were estimated on T2-weighted axial and sagi...

A transient grating method is used to excite and monitor Lamb acoustic waveguide modes in free standing thin polyimide films which are known to have transverse isotropic symmetry. The dispersion of these Lamb modes is used to accurately characterize both the in and out-of-plane elastic moduli in the films. To our knowledge, this is the first example of the noncontact, nondestructive determinati...

The effect of fibre bundling on the effective transverse properties of unidirectional fibre composites has been investigated by way of finite element method and micromechanics models of fibre bundles. Based on the micromechanical model of single-fibre composites, plane strain models for composites reinforced by fibre bundles are presented. The effective elasto-plastic stress /strain behaviour w...

The macroscopic response of hyperelastic fi ber composites is characterized in terms of the behaviors of their constituting phases. To this end, we make use of a unique representation of the deformation gradient in terms of a set of transversely isotropic invariants. Respectively, these invariants correspond to extension along the fi bers, transverse dilatation, out-of-plane shear along the fi ...
