The absorption Ångström exponent of black carbon: from numerical aspects

open access: yes, 2017
. The absorption Angstrom exponent (AAE) is an important aerosol optical parameter used for aerosol characterization and apportionment studies. The AAE of black carbon (BC) particles is widely accepted to be 1.0, although observational estimates give ...

Delay-Exponent of Bilayer Anytime Code

open access: yes, 2014
In this paper, we study the design and the delay-exponent of anytime codes over a three terminal relay network. We propose a bilayer anytime code based on anytime spatially coupled low-density parity-check (LDPC) codes and investigate the anytime ...

A local expression of the Diederich--Fornaess exponent and the exponent of conformal harmonic measures [PDF]

open access: yes, 2015
A local expression of the Diederich--Fornaess exponent of complements of Levi-flat real hypersurfaces is exhibited. This expression describes the correspondence between pseudoconvexity of their complements and positivity of their normal bundles, which ...

Detecting the Temporal Scaling Behavior of the Normalized Difference Vegetation Index Time Series in China Using a Detrended Fluctuation Analysis

open access: yesRemote Sensing, 2015
Vegetation is an important part of terrestrial ecosystems. Although vegetation dynamics have explicit spatial and temporal dimensions, the study of the temporal process is in its infancy.

Global leaf nitrogen and phosphorus stoichiometry and their scaling exponent

open access: yes, 2018
Leaf nitrogen (N) and phosphorus (P) concentrations constrain photosynthetic and metabolic processes, growth and the productivity of plants. Their stoichiometry and scaling relationships regulate the allocation of N and P from subcellular to organism ...

Recent trends in revision knee arthroplasty in Germany

open access: yesScientific Reports, 2021
We aimed to answer the following questions: (1) How did numbers of revision knee arthroplasty procedures develop in Germany over the last decade compared to primary TKA? (2) How high was the percentage of septic interventions in knee prosthesis revisions?

On a new fractional Sobolev space and applications to nonlocal variational problems with variable exponent

open access: yes, 2017
The content of this paper is at the interplay between function spaces $L^{p(x)}$ and $W^{k, p(x)}$ with variable exponents and fractional Sobolev spaces $W^{s, p}$.

Exponent of Cross-Sectional Dependence: Estimation and Inference

open access: yesSocial Science Research Network, 2016
An important issue in the analysis of cross-sectional dependence which has received renewed interest in the past few years is the need for a better understanding of the extent and nature of such cross dependencies.

Strong Converse Exponent for Classical-Quantum Channel Coding [PDF]

open access: yesCommunications in Mathematical Physics, 2014
We determine the exact strong converse exponent of classical-quantum channel coding, for every rate above the Holevo capacity. Our form of the exponent is an exact analogue of Arimoto’s, given as a transform of the Rényi capacities with parameters α>1 ...
