Three algorithms for determining the bulk geometric properties of cellular structures from a stationary digital image are presented. The geometrical properties of interest include cell orientation and cell aspect ratio. With future test data expected to possess high luminance variability, poor contrast near element boundaries and irregular discolouration, this problem is poorly suited for the s...

The signal-to-interference-plus-noise-ratio performance of the multistage linear parallel and successive interference cancellers (LPIC and LSIC) in a long-code code-division multiple-access system is analyzed with a graphic approach in this paper. The decision statistic is modeled as a Gaussian random variable, whose mean and variance can be expressed as functions of moments ofR for the LPIC an...

The M/G/K queueing system is the oldest model for multi-server systems, and has been the topic of performance papers for almost half a century. However, even now, only coarse approximations exist for its mean waiting time. All the closed-form (non-numerical) approximations in the literature are based on the first two moments of the job size distribution. In this paper we prove that no approxima...

We report a computational study of the self-assembly of end-tethered nanorods in a neat system (no solvent). We present morphological phase diagrams for low and moderate aspect ratio rods as a function of inverse temperature vs. relative tether fraction. Our simulations predict that the end-tethered rods self-assemble into hexagonally arranged chiral cylinders, hexagonally perforated lamellae, ...

The gluon dominance model offers a description of multiparticle production in e + e −-annihilation and proton-proton collisions. The multiplicity distributions in e + e − annihilation are well described. The energy dependence of model parameters gives the dynamic parton stage and hadronisation picture. It is shown that this model has confirmed oscillations in sign of the ratio of factorial cumu...

Y${}_{3}$Cu${}_{9}$(OH)${}_{19}$Cl${}_{8}$, also known as Y-kapellasite, realizes an original anisotropic frustrated kagome model. Here, the authors study large phase-pure single crystals, obtained via external gradient method, by susceptibility, specific heat, thermal expansion, neutron scattering, and local $\ensuremath{\mu}$SR NMR techniques. These find subtle structural changes along with l...

An analogue of the Euler top is considered for a pseudo-Euclidean space under consideration. In cases when geometric integral or area vanishes bifurcation diagrams moment map are constructed and homeomorphism class each leaf Liouville foliation determined. For arc diagram, one two possible mutual arrangement moments inertia, types singularities in preimage small neighbourhood this (analogues Fo...

Ga-NMR local susceptibility of the kagomé-based magnet SrCr 9p Ga 12−9p O 19. A high temperature study. Abstract We report a high-T Ga-NMR study in the kagomé-based antiferromagnetic compound SrCr 9p Ga 12−9p O 19 (.81 ≤ p ≤ .96), and present a refined mean-field analysis of the local NMR susceptibility of Cr frustrated moments. We find that the intralayer kagomé coupling is J = 86(6) K, and th...

We investigate the magnetic coupling at the Co/NiO interface using soft x-ray magnetic linear dichroism (XMLD) and circular dichroism taking explicitly into account the recently observed angular dependence of the XMLD with respect to the crystallographic axes. We find that the Co moments are aligned perpendicular to the NiO moments. We discuss the impact of the anisotropic XMLD on the intensity...

It has been shown in recent analyses by ALEPH [1] and OPAL [2] that precision QCD tests are possible with hadronic τ decays by comparing spectral moments of the hadronic decay ratio of the τ with QCD calculations. In principle e+e− data can be used in a similar manner by evaluating spectral moments of R. The current e+e− data is compared with the OPAL τ data and a prediction is made on the achi...
