Planning and Self-Control, but not Working Memory, Directly Predict Multiplication Performance in Adults

open access: yesJournal of Numerical Cognition, 2017
Empirical evidence suggests that working memory (WM) is closely related to arithmetic performance. WM, which is the ability to monitor and update recent information, underlies various cognitive processes and behaviors including planning, self-regulation,

On a Sum of More Complex Product-Type Operators from Bloch-Type Spaces to the Weighted-Type Spaces

open access: yesAxioms, 2023
The aim of the present paper is to completely characterize the boundedness and compactness of a sum operator defined by some more complex products of composition, multiplication, and mth iterated radial derivative operators from Bloch-type spaces to ...

The multiplicative complexity of interval checking

open access: yesIACR Cryptol. ePrint Arch., 2022
We determine the exact AND-gate cost of checking if $a\leq x < b$, where $a$ and $b$ are constant integers. Perhaps surprisingly, we find that the cost of interval checking never exceeds that of a single comparison and, in some cases, it is even lower.

Cryptographic Puzzles and Complex Systems

open access: yes, 2021
A puzzle lies behind password authentication (PA) and blockchain proof of work (PoW). A cryptographic hash function is commonly used to implement them. The potential problem with secure hash functions is their complexity and rigidity.

Towards Formulation of a Complex Binary Number System

open access: yesSultan Qaboos University Journal for Science, 2002
For years complex numbers have been treated as distant relatives of real numbers despite their widespread applications in the fields of electrical and computer engineering.

Individual Differences in Math Ability Determine Neurocognitive Processing of Arithmetic Complexity: A Combined fNIRS-EEG Study

open access: yesFrontiers in Human Neuroscience, 2019
Some individuals experience more difficulties with math than others, in particular when arithmetic problems get more complex. Math ability, on one hand, and arithmetic complexity, on the other hand, seem to partly share neural underpinnings.

Multiple faces of the SAGA complex [PDF]

open access: yesCurrent Opinion in Cell Biology, 2010
The SAGA complex provides a paradigm for multisubunit histone modifying complexes. Although first characterized as a histone acetyltransferase, because of the Gcn5 subunit, SAGA is now known to contain a second activity, a histone deubiquitinase, as well as subunits important for interactions with transcriptional activators and the general ...

Elliptic Curves with Complex Multiplication [PDF]

open access: yes, 2022
openAn elliptic curve has complex multiplication if its ring of endomorphisms is stricly larger than $\mathbb{Z}$, in this case special simmetry arises from the additional structure.

Do evolutionary algorithm dynamics create complex network structures? [PDF]

open access: yes, 2021
This paper presents a novel method for visualizing the dynamics of evolutionary algorithms in the form of complex networks. We discuss the analogy between individuals in populations in an arbitrary evolutionary algorithm and vertices of a complex network,
