MIDAS: a methodological framework for high‐speed high‐energy diffraction microscopy data reduction. Part I: methodology

Acta Crystallographica Section A, EarlyView.
This paper details the complete methodological framework implemented in the MIDAS software for processing high‐energy diffraction microscopy (HEDM) data. We describe the specific algorithms, coordinate systems and physical models used for both far‐field and near‐field HEDM analysis.

Mode characteristics for equilateral triangle optical resonators

, 2006
Mode characteristics of equilateral triangle resonators (ETRs) are analyzed based on the symmetry operation of the point group C-3v. The results show that doubly degenerate eigenstates can be reduced to the A(1) and A(2) representations of C-3v, if the ...

Is Word Order Asymmetry Mathematically Expressible?

Biolinguistics, 2013
The computational procedure for human natural language (CHL) shows an asymmetry in unmarked orders for S, O, and V. Following Lyle Jenkins, it is speculated that the asymmetry is expressible as a group-theoretical factor (included in Chomsky’s third ...

Analysis of semiconductor microlasers with an equilateral triangle resonator by rate equations

, 2001
Semiconductor microlasers with an equilateral triangle resonator (ETR) are analyzed by rate equations with the mode lifetimes calculated by the finite-difference time-domain technique and the Pade approximation.

A continuous‐time random encounter and staying time (REST) model: Moving beyond temporal aggregation in camera‐trap density estimation

Methods in Ecology and Evolution, EarlyView.
Abstract Estimating wildlife population density is fundamental to ecology and conservation. While camera traps have revolutionized the monitoring of medium‐ to large‐sized mammals, estimating the density of unmarked populations remains a major challenge. Current models rely on a critical and often‐violated synchronized activity assumption.

New circle coverings of an equilateral triangle [PDF]

, 1997
Recently, Melissen has determined the thinnest coverings of an equilateral triangle with 1,...,6, and 10 equal circles; see [5,6]. Here, we will determine the thinnest covering with nine circles, and give a new, short prooffor the thinnest covering with ...
