Abstract In this paper a new dissimilarity measure to identify groups of assets dynamics is proposed. The underlying generating process is assumed to be a diffusion process solution of stochastic differential equations and observed at discrete time. The mesh of observations is not required to shrink to zero. As distance between two observed paths, the quadratic distance of the corresponding est...

the effects of chemical and physical treatments on the storage life of bitter lemons in jiroft, kerman province, were investigated. after harvesting, the lemons were treated by curing, fungicide, waxed paper, shrink wrap or using a combination of these treatments. the samples were stored in standard citrus fruit boxes for three months at 85-90% relative humidity at a temperature of 3°c. once a ...

Abstract Given a directed graph G and pair of nodes s t , an - bridge is edge whose removal breaks all paths (and thus appears in paths). Computing bridges basic problem, solvable linear time. In this paper, we consider natural generalisation with the notion “safety” from bioinformatics. We say that walk W safe respect to set $${\mathcal {W}}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/M...

I discuss some of the historical circumstances that drove us to use the lattice as a nonperturbative regulator. This approach has had immense success, convincingly demonstrating quark confinement and obtaining crucial properties of the strong interactions from first principles. I wrap up with some challenges for the future.

Due to some reasons, observed images are degraded which are mainly caused by noise. Recently image denoising using the wavelet transform has been attracting much attention. Waveletbased approach provides a particularly useful method for image denoising when the preservation of edges in the scene is of importance because the local adaptivity is based explicitly on the values of the wavelet detai...

Graphene-sulfur composites with sulfur fractions as high as 87 wt% are prepared using a simple one-pot, scalable method. The graphene envelops the sulfur particles, providing a conductive shrink-wrap for electron transport. These materials are efficient cathodes for Li-S batteries, yielding 93% coulombic efficiency over 50 cycles with good capacity.
