Formulas are derived, by direct integration of the defining definite integrals, for the general geometric mean distance between (i) a point and a line segment; (ii) a point and a rectangular area; (iii) two parallel line segments; (iv) two orthogonal line segments; (v) a line segment an...
Here we show that superior results are obtained by instead using a geometric mean of the harmonic fields to either side of the integration boundary. 展开 关键词: Fourier transforms antenna radiation patterns electric fields electromagnetic wave scattering finite difference time-domain analysis geometry ...
In this paper we discuss the relevancy of the geometric mean as a portfolio selection criteria. A procedure for finding that portfolio with the highest geometric mean when returns on portfolios are lognormally distributed is presented. The development of this algorithm involves a proof that the port...
Using simulated as well as actualtracking data from a representative beam test scenario, we find that thegeometric-mean method gives systematically inaccurate spatial resolutionresults. Good resolutions are estimated as poor and vice versa. The more theresolutions of reference detectors and probed ...

Many bacteria can form wall-deficient variants, or L-forms, that divide by a simple mechanism that does not require the FtsZ-based cell division machinery. Here, we use microfluidic systems to probe the growth, chromosome cycle and division mechanism of
