Symmetric-Difference (Degeneracy) and Signed Tree Models [PDF]
We introduce a dense counterpart of graph degeneracy, which extends the recently-proposed invariant symmetric difference. We say that a graph has sd-degeneracy (for symmetric-difference degeneracy) at most $d$ if it admits an elimination order of its ...

FEBS Letters, EarlyView.Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

A short proof of Brooks’ Theorem for vertex arboricity
AKCE 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,

Frontiers 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 ...

Kramers degeneracy without eigenvectors
, 2012 Wigner gave a well-known proof of Kramers degeneracy for time reversal invariant systems containing an odd number of half-integer spin particles. But Wigner's proof relies on the assumption that the Hamiltonian has an eigenvector, and thus does not apply

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Degeneracy and Complexity in Neuro-Behavioral Correlates of Team Coordination
Frontiers 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.

Degeneracy degrees of constraint collections
, 2003 This paper presents an unifying approach to the theory of degeneracy of basic feasible solutions, vertices, faces, and all subsets of polyhedra. It is a generalization of the usual concept of degeneracy defined for basic feasible solutions of an LP ...

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