Tripotents: a class of strongly clean elements in rings

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018
Periodic elements in a ring generate special classes of strongly clean elements. In particular, elements b such that b = b3+, which are called tripotents and include idempotents, negative of idempotents and order 2 units, are strongly clean.

Idempotent permutations

open access: yesCoRR, 2013
Together with a characteristic function, idempotent permutations uniquely determine idempotent maps, as well as their linearly ordered arrangement simultaneously. Furthermore, in-place linear time transformations are possible between them. Hence, they may be important for succinct data structures, information storing, sorting and searching.

On Discrete Idempotent Paths [PDF]

open access: yes, 2019
The set of discrete lattice paths from (0, 0) to (n, n) with North and East steps (i.e. words w $\in$ { x, y } * such that |w| x = |w| y = n) has a canonical monoid structure inherited from the bijection with the set of join-continuous maps from the chain { 0, 1,. .. , n } to itself.

Musical Mereology

open access: yesPacific Philosophical Quarterly, EarlyView.
ABSTRACT I develop an axiomatic system of mereology that accounts for the ways in which musical works can be said to have parts. I distinguish two fundamental modes of composition that musical works exhibit: successive composition, whereby sound events are concatenated in time, and simultaneous composition, whereby sound events occur at the same time ...

Commuting idempotents of an H∗-algebra

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
Commutative H∗-algebra is characterized in terms of idempotents. Here we offer three characterizations.

Tropical algebra for noise removal and optimal control

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2023
Algorithms for noise removal are either complex or ineffective, and the optimal control with inequality constrains makes the algorithm even more complex.

On the idempotent and nilpotent sum numbers of matrices over certain indecomposable rings and related concepts

open access: yesМатематичні Студії, 2021
We investigate a few special decompositions in arbitrary rings and matrix rings over indecomposable rings into nilpotent and idempotent elements. Moreover, we also define and study the nilpotent sum trace number of nilpotent matrices over an arbitrary ...

Advances in large DNA fragment assembly for microbial cell factory engineering

open access: yesQuantitative Biology, Volume 14, Issue 3, September 2026.
Abstract The efficient, rapid, and reliable assembly of DNA fragments is essential for advancing metabolic engineering and synthetic biology. With the rapid advancement of DNA synthesis and assembly technologies, the scale of DNA assembly has expanded from single genes to metabolic pathways and even genomes.
