Physical Chemistry Chemical Physics, 2014
Atomistic simulation of chemical systems is currently limited by the elementary description of electrostatics that atomic point-charges offer. Unfortunately, a model of one point-charge for each atom fails to capture the anisotropic nature of electronic features such as lone pairs or π-systems. Higher order electrostatic terms, such as those offered by

Multibeam and multipolarization antenna
2006 First European Conference on Antennas and Propagation, 2006The design of a novel reconfigurable antenna for MIMO systems is presented. Simulation and experimental results shows its capabilities in a multibeam reconfiguration in a 4? steradians environment. It can allow an enhancement in wireless communication employing multipath channel combining with a radiation pattern diversity.

Canadian Mathematical Bulletin, 1992
AbstractIt is proved that a compact subset of a finite product of Brelot harmonic spaces is multipolar if it is a locally multipolar set.

Gastrointestinal Endoscopy Clinics of North America, 2003
Multipolar electrocoagulation (MPEC) is a readily available technique that can be applied for endoscopic ablation of Barrett's esophagus. MPEC, in combination with high dose proton pump inhibitor therapy or antireflux surgery, results in normal squamous epithelium in most patients without major adverse effects.

Multipolar Continuum Mechanics
Archive for Rational Mechanics and Analysis, 1964A general theory of multipolar displacement and velocity fields with corresponding multipolar body and surface forces and multipolar stresses is developed using an energy principle, an entropy production inequality and invariance conditions under superposed rigid body motions.

Bipolar and Multipolar Radiofrequency
Dermatologic Surgery, 2014The increased demand for anti-aging treatments over the past decade has fueled the development of multimodality devices. This allows for more efficacious treatment of dermal defects, excess adiposity, and skin laxity. Radiofrequency (RF) devices are constantly evolving and consequently adding multiple indications for their use.

Bipolar and Multipolar Coordinates
2000Bipolar or multipolar coordinates offer useful insights and advantages over Cartesian coordinates in certain geometrical problems. In bipolar coordinates (r 1, r 2) the “simplest” curves are the conics, ovals of Cassini, Cartesian ovals, and their special cases, which are characterized by linear or hyperbolic relations in the (r 1, r 2) plane.

Multipolar Meiosis in Elephantulus
Nature, 1949ONE of the males used for a cytogenetical investigation of Elephantulus myurus jamesoni, the South African jumping shrew, showed a high incidence of multipolar meiotic divisions. This was not referred to in the original reports of the cytogenetics of Elephantulus1,2 and is described below. In a count of a hundred first meiotic metaphases and anaphases,

The most important impulse to the creation of the theory, is its ability to be a framework for the mathematical theory of compressible, heat conductive fluids. The theory provides proof of the existence of global (in time) solutions, what in spite of big efforts, the classical theory, based on linear Stoke’s stress-strain relation, does not make ...
