INTRODUCTION Phentolamine mesylate has been reported to be an effective local anesthetic reversal agent for soft tissue but has not been studied regarding reversal of pulpal anesthesia. The authors conducted a prospective randomized, single-blind study comparing the reversal of pulpal and soft tissue anesthesia when phentolamine was administered at 30 minutes versus 60 minutes after the adminis...

We call a system bouncing ball billiard if it consists of a particle that is subject to a constant vertical force and bounces inelastically on a one-dimensional vibrating periodically corrugated floor. Here we choose circular scatterers that are very shallow, hence this billiard is a deterministic diffusive version of the well-known bouncing ball problem on a flat vibrating plate. Computer simu...

This paper reports the reduction of package-stresses by in tm ducing a decoupling zone directly m u n d a sensor structure. Different geometries of the decoupling zones are compared, using the Fdte Element Method (FEM) and analytical models. A large reduction is obtained in case of a corrugated decoupling zone. To optimize the reduction, an analytical description of a ring-shaped V-groove is gi...

A multidimensional, nonlinear finite-difference time-domain (NL-FDTD) simulator, which is constructed from a self-consistent solution of the full-wave vector Maxwell equations and dispersive (Lorentz), nonlinear (finitetime-response Raman and instantaneous Kerr) materials models, is used to study finite-length, corrugated, optical waveguide output couplers and beam steerers. Multiple-cycle, ult...

In this paper we show that the diffraction condition for the scattering of atoms from surfaces leads to the appearance of a distinct type of classical singularity. Moreover, it is also shown that the onset of classical trapping or classical chaos is closely related to the bifurcation set of the diffraction-order function around the surface points presenting the rainbow effect. As an illustratio...

This paper addresses an important issue of light throughput of a metal-coated tapered tip for scanning near-field microscope (SNOM). Corrugations of the interface between the fiber core and metal coating in the form of parallel grooves of different profiles etched in the core considerably increase the energy throughput. In 2D FDTD simulations in the Cartesian coordinates we calculate near-field...

In the structure of the title coordination polymer, {(C(8)H(20)N)[Sn(3)(CH(3))(9)(SO(4))(2)]}(n), each of the three Sn(IV) atoms is coordinated in a trigonal-bipyramidal manner by three methyl groups in the equatorial plane and by two O atoms of SO(4) (2-) anions in the axial positions. The μ(3)-bridging mode of the sulfate anions leads to the formation of corrugated anionic layers parallel to ...
