Renormalized Energy with Vortices Pinning Effect
Journal of Partial Differential Equations, 2000This theoretical paper is a continuation of a previous paper [\textit{S. Ding, Z. Liu}, J. Partial Differ. Equations 10, No.~2, 174-192 (1997; Zbl 0887.35022)]. The author derives the renormalized energy to further determine the location of vortices for the variational problem related to the superconducting thin films having variable thickness.

Effect of pin depth on the dislodgement of pin-retained composite resin crown bases
The Journal of Prosthetic Dentistry, 1981Abstract A laboratory study was carried out to evaluate the effect of pin depth into dentin on the retention of composite resin crown bases. The crown bases were subjected to laterally applied dislodging forces. The results showed no statistically significant difference at the 95% confidence level in the retention of crown bases retained with pins ...

Neuroticism and cortisol: Pinning down an expected effect
International Journal of Psychophysiology, 2014There are strong theoretical arguments that those high on Neuroticism (N) should normally exhibit higher prevailing levels of the stress-linked hormone cortisol (C), but findings are inconsistent, probably reflecting methodological weaknesses especially in taking account of C's diurnal cycle.High and low N students [Total N=118; mean age=20.99years ...

Effects of Pin Detached Space on Heat Transfer and Pin-Fin Arrays
Journal of Heat Transfer, 2012Heat transfer and pressure characteristics in a rectangular channel with pin-fin arrays of partial detachment from one of the endwalls have been experimentally studied. The overall channel geometry (W = 76.2 mm, E = 25.4 mm) simulates an internal cooling passage of wide aspect ratio (3:1) in a gas turbine airfoil. With a given pin diameter, D = 6.35 mm

Critical currents and the effects of pinning
IEEE Transactions on Magnetics, 1991The bulk magnetic properties of sintered materials are treated as those of a standard magnetic material with a permeability dependent on the porosity. If J/sub c/ is expressed as a function of the internal H instead of the applied field, it is much more constant.

The Effect of Angled Insertion on Halo Pin Fixation
Spine, 1989This study evaluated the effect of angled insertion of halo pins on the biomechanical characteristics of the halo pin-calvarium complex. Halo pins were inserted into isolated calvarium sections at 90 degrees, 75 degrees, and 60 degrees to the surface of the bone at an insertional torque of 0.68 N-m (6 inch-pounds).

Effects of the Hubbard interaction and electrostatic pinning in polyacetylene
Physical Review B, 1988Abstract : The discrete model for the coupled electron phonon system in polyacetylene has been extended to include the electronic effects of electrostatic pinning and the Hubbard interaction in the unrestricted Hartree-Fock approximation. To fit experimental structural data, the Hamiltonian also includes the lattice kinetic energy and the coupling of ...

Interfacial Crack Pinning: Effect of Nonlocal Interactions
Physical Review Letters, 1995We propose a perturbative approach to describe the evolution of an interfacial crack between two elastic solids with quenched disorder. The driving force is the stress intensity factor along the crack front. The latter is expressed as a function of the entire crack geometry through a linear convolution with a long-ranged kernel using a first order ...

Anisotropy, pinning, and the mixed-state Hall effect
Physical Review B, 1995We have studied the mixed-state Hall effect of the high-{ital T}{sub {ital c}} superconductors Nd{sub 1.85}Ce{sub 0.15}CuO{sub 4} (NCCO), Tl{sub 2}Ba{sub 2}CaCu{sub 2}O{sub 8} (Tl2212), and YBa{sub 2}Cu{sub 3}O{sub 7} (YBCO), and the isotropic low-{ital T}{sub {ital c}} superconductor amorphous Mo{sub 3}Si ({ital a}-Mo{sub 3}Si).
