Parton Distributions [PDF]

open access: yesInternational Journal of Modern Physics A, 2003
I discuss our current understanding of parton distributions. I begin with the underlying theoretical framework, and the way in which different data sets constrain different partons, highlighting recent developments.

New proof of Ahlfors lemma about Green Stokes formula for distributions [PDF]

open access: yesBulletin of Natural Sciences Research, 2022
The paper presents a new proof of Ahlfors lemma about Green Stokes formula for distributions. The proof is performed directly using test functions instead of using convolutions.

RELIABILITY OF SERIAL-PARALLEL NETWORKS VS RELIABILITY OF PARALLELSERIAL NETWORKS WITH CONSTANT NUMBERS OF SUB-NETWORKS AND UNITS [PDF]

open access: yesJournal of Engineering Science (Chişinău), 2022
In this paper it is performed, based on dynamic models, a comparative analysis of the reliability of two types of networks: serial-parallel and parallel-serial networks when the numbers of subnets and units in each subnet are predefined, constant numbers,

On Generalizing Sarle’s Bimodality Coefficient as a Path towards a Newly Composite Bimodality Coefficient

open access: yesMathematics, 2022
Determining whether a distribution is bimodal is of great interest for many applications. Several tests have been developed, but the only ones that can be run extremely fast, in constant time on any variable-size signal window, are based on Sarle’s ...

Power-Law Distributions in Empirical Data [PDF]

open access: yesSIAM Review, 2007
Power-law distributions occur in many situations of scientific interest and have significant consequences for our understanding of natural and man-made phenomena. Unfortunately, the detection and characterization of power laws is complicated by the large

On the equivalence between weak BMO and the space of derivatives of the Zygmund class

open access: yesDemonstratio Mathematica, 2021
In this paper, we will discuss the space of functions of weak bounded mean oscillation. In particular, we will show that this space is the dual space of the special atom space, whose dual space was already known to be the space of derivative of functions

The “Second Derivative” of a Non-Differentiable Function and its Use in Interval Optimization Methods

open access: yesJournal of Telecommunications and Information Technology, 2023
The paper presents an idea to use weak derivatives in interval global optimization. It allows using the Newton operator to narrow domains of non-differentiable functions. Preliminary computational experiments are also presented.
