Background Symptoms, endoscopy, histology, and biomarkers are used to evaluate disease activity and response to therapy in ulcerative colitis (UC). Histologic disease activity may persist in ~25% of patients with normal-appearing endoscopic mucosa, a

Background Several instruments have been used in clinical trials of pouchitis to define eligibility criteria and outcome measures but have not been formally validated. A need remains for a validated pouchitis instrument that is suitable for use in no

Recently published data on the variation with applied bias and temperature of steady-state photoluminescence and photoconductivity from a series of GaAs/AlGaAs single quantum well p-i-n structures are subjected to detailed theoretical analysis, using

We have studied the variation with applied bias and temperature of steady state photoluminescence (DCPL) and photoconductivity (DCPC) from a series of GaAs/AlGaAs single quantum well, p-i-n structures with different well widths. We present the DCPC a

Heisenberg's correspondence principle is applied to the matrix elements of the rotation operator; in this way, an approximation for the reduced rotation matrix elements dJM'M( theta ) in terms of Bessel functions is obtained. It is shown that two dis

For pt.I see ibid., vol.25, no.20, p.4045-57 (1992). Previous work on the correspondence principle limit of matrix elements of tensor operators is extended to more complex matrix elements. Limiting forms of several such matrix elements are obtained;

Heisenberg's form of the correspondence principle is applied to the matrix elements of tensor operators. A correspondence limit of the Wigner-Eckart theorem is obtained. It is shown that the Clebsch-Gordan coefficient tends in this limit to the produ

For electron micrographs taken with the offset bright-field configuration (interference microscopy), a transfer function is derived which includes the effects of angular and energy spread in the illumination on spherical aberration, defocussing and c

The time-dependent sudden approximation is applied to dipole-dipole scattering. It is shown to be reducible to an analytic form of extreme simplicity, allowing rotor-rotor inelastic cross sections to be calculated with minimal effort. The possibility

On the basis of a kinematic analysis of the direction of momentum transfer, the Bethe theory is applied to the polarization of atomic line radiation by electron impact. A simple, analytic formula is obtained for the line polarization P as a function
