A one parameter family of Calabi-Yau manifolds with attractor points of rank two

Journal of High Energy Physics, 2020
In the process of studying the ζ-function for one parameter families of Calabi-Yau manifolds we have been led to a manifold, first studied by Verrill, for which the quartic numerator of the ζ-function factorises into two quadrics remarkably often.

Limit Behavior of Quadratic Forms of Moving Averages and Statistical Solutions of the Burgers′ Equation

Journal of Multivariate Analysis, 1995
Let \(\dots, X_{-1}, X_ 0, X_ 1, \dots\) be symmetric i.i.d. random variables belonging to the domain of normal attraction of an \(\alpha\)- stable distribution with \(1 < \alpha < 2\), and let \(c_ j = j^{-\beta} \Lambda (j)\) with \(\alpha \beta > 1\) and slowly varying \(\Lambda (j)\).

Unveiling Aggregation‐Induced Singlet Fission in Push–Pull Diketopyrrolopyrrole Water Dispersed Nanoaggregates and Thin Films

Advanced Functional Materials, EarlyView.
Aggregates of diketopyrrolopyrrole dipolar and quadrupolar systems exhibit panchromatic absorption spectra extending in the entire visible range. Upon aggregation in water and in the solid state, their fluorescence is almost completely quenched and their singlet excited state lifetime is significantly shortened.

An Overview of the Pathway Idea and Its Applications in Statistical and Physical Sciences

Axioms, 2015
Pathway idea is a switching mechanism by which one can go from one functional form to another, and to yet another. It is shown that through a parameter α, called the pathway parameter, one can connect generalized type-1 beta family of densities ...

Multiple Twinning in Nacre and Aragonite

Advanced Functional Materials, EarlyView.
Electron backscatter diffraction map of a cluster of geologic aragonite, exhibiting single, double, and triple twins. The whole cluster is approximately 2 cm wide. Colors indicate crystal orientations, so that pixels where the a‐, b‐, and c‐axis is perpendicular to the image plane are green, red, and blue, respectively.

Estimating slope from raster data – a test of eight algorithms at different resolutions in flat and steep terrain

Geodesy and Cartography, 2013
Different slope algorithms can result in totally different estimates. In the worst case, this may lead to inappropriate and useless modelling estimates.

Roll‐to‐Roll Mechanical Exfoliation for Large‐Area van der Waals Films with Preserved Crystallographic Alignment

Advanced Functional Materials, EarlyView.
A roll‐to‐roll exfoliation method is demonstrated that preserves the crystallographic alignment of anisotropic 2D materials over large areas, enabling scalable fabrication of directional electronic and optoelectronic devices. Abstract Anisotropic 2D materials such as black phosphorus (BP), GeS or CrSBr, exhibit direction‐dependent optical and ...

The probability density function of spectral correlation function estimates

EURASIP Journal on Advances in Signal Processing
Since published in 1988, the FFT Accumulation Method (FAM) has been used extensively to compute the Spectral Correlation Function (SCF) and the Spectral Coherence Function (SCoF) to obtain or detect cyclic features of cyclostationary signals.
