Group distance magic labeling of the Cartesian product of two directed cycles

Electronic Research Archive
Let $ \overrightarrow{G} $ be a finite simple directed graph with $ n $ vertices, and let $ \Gamma $ be a finite abelian group of order $ n $. A $ \Gamma $-distance magic labeling is a bijection $ \varphi:V(\overrightarrow{G})\longrightarrow \Gamma $ for

Hidden communication aspects in the exponent of Zipf's law [PDF]

, 2005
This article focuses on communication systems following Zipf’s law, in a study of the rel-ationship between the properties of those communication systems and the exponent of the law.

On Brownian Disconnection Exponents [PDF]

Bernoulli, 1995
The paper starts with a short, intuitive revision of the derivation of the strictly positive constant \(\gamma\), the disconnection exponent for the two-dimensional Brownian motion. The right-hand side of the well-known double inequality \({1\over 2\pi} \leq \gamma \leq {1\over 2}\) is improved by the estimate \(\gamma \leq {1\over 2} - {1\over 2 ...

Estimating Loynes’ exponent [PDF]

Queueing Systems, 2011
Loynes' distribution, which characterizes the one dimensional marginal of the stationary solution to Lindley's recursion, possesses an ultimately exponential tail for a large class of increment processes. If one can observe increments but does not know their probabilistic properties, what are the statistical limits of estimating the tail exponent of ...

The Diverse Neuromuscular Spectrum of VPS13A Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective VPS13A disease (chorea‐acanthocytosis) is a rare neurodegenerative disorder caused by biallelic variants in VPS13A, typically presenting with hyperkinetic movement disorders, while neuromuscular signs are often mild. The aim of the project was to investigate the frequency and severity of neuromuscular impairment in VPS13A disease ...

Percolation Threshold, Fisher Exponent, and Shortest Path Exponent for 4 and 5 Dimensions

, 2001
We develop a method of constructing percolation clusters that allows us to build very large clusters using very little computer memory by limiting the maximum number of sites for which we maintain state information to a number of the order of the number ...

A Multi‐Center Retrospective Cohort Study of Neurosarcoidosis Myelitis: Current Observations and Future Directions

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The optimal treatment for neurosarcoidosis myelitis is uncertain. We characterize incident neurosarcoidosis myelitis and assess treatment response by MRI and clinical scales. Methods Incident probable or definite neurosarcoidosis myelitis in adults was retrospectively identified from 13 academic medical centers.

Exact Random Coding Secrecy Exponents for the Wiretap Channel

, 2016
We analyze the exact exponential decay rate of the expected amount of information leaked to the wiretapper in Wyner's wiretap channel setting using wiretap channel codes constructed from both i.i.d. and constant-composition random codes. Our analysis for

Series with general exponents

Journal of Mathematical Analysis and Applications, 1991
We define the Artinian and Noetherian algebra which consist of formal series involving exponents which are not necessarily integers. All of the usual operations are defined here and characterized. As an application, we compute the algebra of symmetric functions with nonnegative real exponents.
