A NEW METHOD FOR CONSTRUCTING PARTIAL ONE TO ONE TRANSFORMATION SEMIGROUP USING TWO LINE NOTATION

open access: yesAcademy Journal of Science and Engineering, 2022
In this paper, we provide a method of constructing finite one to one transformation semigroup from the full one to one transformation semigroup using some pattern called transitive.

The join of split graphs whose completely regular endomorphisms form a monoid

open access: yesOpen Mathematics, 2017
In this paper, completely regular endomorphisms of the join of split graphs are investigated. We give conditions under which all completely regular endomorphisms of the join of two split graphs form a monoid.

On Nilpotent Subsemigroups in some Matrix Semigroups [PDF]

open access: yes, 2007
2000 Mathematics Subject Classification: 20M20, 20M10.We describe maximal nilpotent subsemigroups of a given nilpotency class in the semigroup Ωn of all n × n real matrices with non-negative coefficients and the semigroup Dn of all doubly stochastic real

Projecting future damage costs of non‐native species using combined dynamical and cost–density equations

open access: yesEcological Applications, Volume 36, Issue 5, July 2026.
Abstract Biological invasions threaten biodiversity, economic stability, and public health, exacerbated by intensive global trade and transport. The economic costs of these invasions have exceeded US$2 trillion globally and continue to increase. Although past invasion costs have been described across various contexts, there are few robust projections ...

Generation cycles in experimental populations of a multivoltine insect

open access: yesJournal of Animal Ecology, Volume 95, Issue 5, Page 782-794, May 2026.
Although theory suggests various mechanisms by which environmental and ecological factors may drive generational fluctuations, our field‐cage experiment is the first to demonstrate how internal dynamics and external disturbances jointly produce synchronised, large‐scale outbreak cycles.

Efficacy of Der f 2/Zen 1‐LAMP1 Plasmid‐Based Vaccine Immunotherapy in Dogs With Atopic Dermatitis: A Proof‐of‐Concept Study

open access: yesVeterinary Dermatology, Volume 37, Issue 2, Page 306-318, April 2026.
Background: DNA‐based vaccination rapidly induces strong cellular and humoral immune responses, which may be enhanced by inclusion of lysosomal‐associated membrane protein‐1 (LAMP). Objectives: This proof‐of‐concept study evaluated the efficacy and safety of a Der f 2/Zen 1‐LAMP‐based DNA vaccine immunotherapy in client‐owned dogs with nonseasonal AD ...

Reducing data processing effort in camera trap density estimation: Extending the REST model by explicitly modelling animal detection processes

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 3, Page 850-862, March 2026.
Abstract Accurate and reliable estimation of wildlife population density is fundamental to effective conservation and management. While camera traps show potential for monitoring ground‐dwelling mammal densities, labour‐intensive data processing remains a significant constraint. Ideally, conservation efforts would benefit from the continuous monitoring

The role of child language ability and parental mentalization in early child dysregulation

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 47, Issue 1, January 2026.
Abstract Dysregulation in early childhood is associated with increased vulnerability to psychopathology and poor psychosocial outcomes. While there is evidence that both child language ability and parental mentalization are associated with dysregulation in early childhood, there is little understanding of the relationships between these variables, and ...

An Application of the Natural Partial Order Relation on the Generalized Semigroup of Transformation With Invariant Set

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
Let X be a nonempty set and TX be the full transformation semigroup on X. For ∅≠Y⊆X, the semigroup of all transformations that leave Y invariant in TX is denoted as S(X, Y) = {f ∈ TX : f(Y)⊆Y}. We fix an element θ ∈ S(X, Y) and specify an operation ∗ on S(X, Y) by f∗g = fθg, where fθg denotes the produce of θ, g and f in the general sense.
