A short proof of Brooks’ Theorem for vertex arboricity

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
The vertex-arboricity of a graph is the minimum number of subsets that the vertices of can be partitioned so that the subgraph induced by each set of vertices is a forest. Kronk and Mitchem proved a generalization of Brooks’ Theorem for vertex arboricity,

Degeneracy and stability in neural circuits of dopamine and serotonin neuromodulators: A theoretical consideration

open access: yesFrontiers in Computational Neuroscience, 2023
Degenerate neural circuits perform the same function despite being structurally different. However, it is unclear whether neural circuits with interacting neuromodulator sources can themselves degenerate while maintaining the same neuromodulatory ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Reaction diffusion equations with boundary degeneracy

open access: yesElectronic Journal of Differential Equations, 2016
In this article, we consider the reaction diffusion equation $$ \frac{\partial u}{\partial t} = \Delta A(u),\quad (x,t)\in \Omega \times (0,T), $$ with the homogeneous boundary condition.

Maximal Cliques as a Normal Form in the Algebra of Graphs: Compression by Modular Decomposition and an Enumeration Algorithm

open access: yesMathematics
The finite simple graphs with vertices in a set S form an algebra G(S) under union and join, generated by the one-vertex graphs. We show that this algebra has a canonical normal form whose data are exactly the maximal cliques of the graph.

Degeneracy and Complexity in Neuro-Behavioral Correlates of Team Coordination

open access: yesFrontiers in Human Neuroscience, 2020
Team coordination—members of a group acting together rather than performing specific actions individually—is essential for success in many real-world tasks such as military missions, sports, workplace, or school interactions.

On Breaking Cosmic Degeneracy [PDF]

open access: yesThe Astrophysical Journal, 1998
It has been argued that the power spectrum of the anisotropies in the Cosmic Microwave Background (CMB) may be effectively degenerate, namely that the observable spectrum does not determine a unique set of cosmological parameters. We describe the physical origin of this degeneracy and show that at small angular scales it is broken by gravitational ...

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

open access: yesMolecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

“Nature Made Us This Way…”: Crime without Punishment? (Fyodor Dostoevsky and Ivan Bunin). Article 2: “Are There Such Signs at Birth?” [PDF]

open access: yesДостоевский и мировая культура: Филологический журнал
The article examines the thesis of marginal anthropology as represented by Fyodor Dostoevsky in the novel Crime and Punishment and creatively reinterpreted by Ivan Bunin in the short story “Loopy Ears,” under the influence of the achievements of the ...

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

open access: yesFEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.
