On Hurst exponent estimation under heavy-tailed distributions

, 2012
In this paper, we show how the sampling properties of the Hurst exponent methods of estimation change with the presence of heavy tails. We run extensive Monte Carlo simulations to find out how rescaled range analysis (R/S), multifractal detrended ...

Quantified exponence constraints and the typology of exponence

Proceedings of the Annual Meetings on Phonology, 2018
Both phonologically conditioned suppletive allomorphy (PCSA) and multiple exponence (ME) involve one-to-many mapping between morphosyntactic information and phonological representations. Though they are usually viewed as separate phenomena, the plural marking of Lower Jubba Maay exhibits properties of both PCSA and ME, indicating that they are ...

Thrombolytic proteins profiling: High‐throughput activity, selectivity, and resistance assays

FEBS Open Bio, EarlyView.
We present optimized biochemical protocols for evaluating thrombolytic proteins, enabling rapid and robust screening of enzymatic activity, inhibition resistance, and fibrin affinity, stimulation, and selectivity. The outcome translates to key clinical indicators such as biological half‐life and bleeding risk. These assays streamline the development of

The minimum exponent of the primitive digraphs on the given number of arcs [PDF]

Opuscula Mathematica, 2004
Primitive digraphs on \(n\) vertices, \(k\) arcs and girth \(s\) are considered. By \(a(n,k,s)\) we mean the minimum exponent taken over all such digraphs. We estimate the number \(a(n,k,s)\) using the Frobenius number for special values of \(k\) and \(s\

Simplified Successive Cancellation Decoding of Polar Codes With Medium-Dimensional Binary Kernels

IEEE Access, 2018
A method is proposed, called l-formula, to design efficient successive cancellation (SC) decoding of polar codes with medium-dimensional binary kernels (dimensions up to 16).

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.

SmallTalk: a novel small‐sized fusion tag for peptide expression and purification

FEBS Open Bio, EarlyView.
The SmallTalk fusion tag allows for the efficient expression and purification of soluble recombinant proteins or peptides in Escherichia coli. Testing with SmallTalk‐GFP confirmed that the proteins were soluble and folded correctly, while SmallTalk‐Bin1b maintained its antimicrobial activity against various bacterial isolates. This streamlined workflow

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

Dynamic Critical approach to Self-Organized Criticality

, 2005
A dynamic scaling Ansatz for the approach to the Self-Organized Critical (SOC) regime is proposed and tested by means of extensive simulations applied to the Bak-Sneppen model (BS), which exhibits robust SOC behavior.

Mapped Exponent and Asymptotic Critical Exponent of Words

We study how much injective morphisms can increase the repetitiveness of a given word. This question has a few possible variations depending on the meaning of ``repetitiveness''. We concentrate on fractional exponents of finite words and asymptotic critical exponents of infinite words.
