In situ imagery unravels resources exploitation strategies among ant communities in a tropical agrosystem

open access: yesEcosphere
Ants are one of the most widespread groups of insects, but the mechanisms allowing them to coexist despite having similar nutritional needs remain unclear.

Loss of ecologically important genetic variation in late generation hybrids reveals links between adaptation and speciation

open access: yesEvolution Letters, 2020
Adaptation to contrasting environments occurs when advantageous alleles accumulate in each population, but it remains largely unknown whether these same advantageous alleles create genetic incompatibilities that can cause intrinsic reproductive isolation

Total domination and least domination in a tree

open access: yesDiscrete Mathematics, 2003
A subset \(X\) of the vertex set \(V(G)\) of a graph \(G\) is called dominating (or total dominating) in \(G\), if for each \(x\in V(G)- X\) (or for each \(x\in V(G)\), respectively) there exists \(y\in X\) adjacent to \(x\). The least number of vertices of a dominating (or total dominating) set in \(G\) is the domination number \(\gamma(G)\) (or the ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Generalized domination and efficient domination in graphs

open access: yesDiscrete Mathematics, 1996
The closed neighbourhood of a vertex \(v\) of a graph \(G\) is the set consisting of \(v\) and of all vertices adjacent to \(v\) in \(G\). A function \(f\) which maps the vertex set \(V(G)\) of \(G\) onto a subset \(Y\) of the set of real numbers is called \(Y\)-dominating in \(G\), if the sum of its values over the closed neighbourhood of each vertex \

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Species richness, composition, and dominance of core and climate relicts of African miombo woodlands

open access: yesEcosphere
The miombo woodlands, which span about 10% of the African continent, are essential for the ecosystem services they provide. These woodlands are mainly dominated by the genera Julbernardia, Isoberlinia, and Brachystegia.

Relating 2-rainbow domination to Roman domination

open access: yesDiscussiones Mathematicae Graph Theory, 2017
For a graph $G$, let $γ_R(G)$ and $γ_{r2}(G)$ denote the Roman domination number of $G$ and the $2$-rainbow domination number of $G$, respectively. It is known that $γ_{r2}(G)\leq γ_R(G)\leq \frac{3}{2}γ_{r2}(G)$. Fujita and Furuya (Difference between 2-rainbow domination and Roman domination in graphs, Discrete Applied Mathematics 161 (2013) 806-812 ...
