Essential obstacles to Helly circular-arc graphs
, 2022 A Helly circular-arc graph is the intersection graph of a set of arcs on a circle having the Helly property. We introduce essential obstacles, which are a refinement of the notion of obstacles, and prove that essential obstacles are precisely the minimal

Description of shape patterns using circular arcs for object detection
IET Computer Vision, 2013 The authors propose a novel object detection algorithm based on shape matching using a single sketch of an object. The proposed algorithm uses circular arc segments to describe image edges; this approach is advantageous for shape description, shape ...

Lombardi drawings of knots and links
Journal of Computational Geometry, 2019 Knot and link diagrams are projections of one or more 3-dimensional simple closed curves into $\mathbb{R}^2$, such that no more than two points project to the same point in $\mathbb{R}^2$.

On powers of circular arc graphs and proper circular arc graphs
Discrete Applied Mathematics, 1996 Let \(\mathcal K\) denote the class of circular arc graphs. The author gives a new proof that if a graph \(G\in {\mathcal K}\), then the power \(G^n\in {\mathcal K}\) for any positive integer \(n\). Moreover, he proves that if \(G^n\in {\mathcal K}\) then \(G^{n+2}\in {\mathcal K}\) and if \(\text{diam}(G^n)\geq 4\) then \(G^n\in {\mathcal K}\) implies

The Topological Connectivity of the Independence Complex of Circular-Arc Graphs
Universal Journal of Mathematics and Applications, 2019 Let us denoted the topological connectivity of a simplicial complex $C$ plus 2 by $\eta(C)$. Let $\psi$ be a function from class of graphs to the set of positive integers together with $\infty$. Suppose $\psi$ satisfies the following properties: \newline

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.

Molecular Oncology, EarlyView.Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.
