Edge‐minimum saturated k‐planar drawings

Journal of Graph Theory, Volume 106, Issue 4, Page 741-762, August 2024.
Abstract For a class D of drawings of loopless (multi‐)graphs in the plane, a drawing D ∈ D is saturated when the addition of any edge to D results in D ′ ∉ D—this is analogous to saturated graphs in a graph class as introduced by Turán and Erdős, Hajnal, and Moon.

Calculating functional diversity metrics using neighbor‐joining trees

Ecography, Volume 2024, Issue 7, July 2024.
The study of functional diversity (FD) provides ways to understand phenomena as complex as community assembly or the dynamics of biodiversity change under multiple pressures. Different frameworks are used to quantify FD, either based on dissimilarity matrices (e.g. Rao entropy, functional dendrograms) or multidimensional spaces (e.g.

On Bogovski\u{\i} and regularized Poincar\'e integral operators for de Rham complexes on Lipschitz domains

, 2009
We study integral operators related to a regularized version of the classical Poincar\'e path integral and the adjoint class generalizing Bogovski\u{\i}'s integral operator, acting on differential forms in $R^n$.

Compact convex sets free of inner points in infinite‐dimensional topological vector spaces

Mathematische Nachrichten, Volume 297, Issue 5, Page 1668-1677, May 2024.
Abstract An inner point of a non‐singleton convex set M$M$ is a point x∈M$x\in M$ satisfying that for all m∈M∖{x}$m\in M\setminus \lbrace x\rbrace$ there exists n∈M∖{m,x}$n\in M\setminus \lbrace m,x\rbrace$ such that x∈(m,n)$x\in (m,n)$. We prove the existence of convex compact subsets free of inner points in the infinite‐dimensional setting. Following

Starlikeness of sections of univalent functions [PDF]

Rocky Mountain Journal of Mathematics, 2014
Let ${\S}$ be the class of all normalized analytic and univalent functions in the unit disk $\ID$. In this paper, we determine condition so that each section $s_{n}(f,z)$ of $f\in {\S}$ is starlike in the disk $|z|\lt r_n$. In particular, $s_{n}(f,z)$ is starlike in $|z|\leq 1/2$ for $n \geq 47$.

Ice age land bridges to continental islands: Repeated migration of the forest‐dwelling sable in northeastern Asia

Journal of Biogeography, Volume 51, Issue 5, Page 924-939, May 2024.
Abstract Aim The continental island system comprising Sakhalin, Hokkaido and the southern Kuril Islands (SHSK) in northeastern Asia serves as one of the southernmost habitats for many boreal and arctic organisms, with colonization via land bridges formed during glacial periods.

The Loewner–Kufarev energy and foliations by Weil–Petersson quasicircles

Proceedings of the London Mathematical Society, Volume 128, Issue 2, February 2024.
Abstract We study foliations by chord–arc Jordan curves of the twice punctured Riemann sphere C∖{0}$\mathbb {C} \setminus \lbrace 0\rbrace$ using the Loewner–Kufarev equation. We associate to such a foliation a function on the plane that describes the “local winding” along each leaf. Our main theorem is that this function has finite Dirichlet energy if

Hankel Determinants for the Logarithmic Coefficients of a Subclass of Close‐to‐Star Functions

Journal of Mathematics, Volume 2024, Issue 1, 2024.
Suppose that ST1 is a class of close‐to‐star functions. In this paper, we investigated the estimate of Zalcman functional on the logarithmic coefficients and the third Hankel determinant for the class ST1 with the determinant entry of logarithmic coefficients.

Cluster synchronization of starlike networks with normalized Laplacian coupling: master stability function approach

, 2015
A generalized model of starlike network is suggested that takes into account non-additive coupling and nonlinear transformation of coupling variables. For this model a method of analysis of synchronized cluster stability is developed.

Macromolecular Poly(N‐isopropylacrylamide) (PNIPAM) in Cancer Treatment and Beyond

Advances in Polymer Technology, Volume 2024, Issue 1, 2024.
Poly(N‐isopropylacrylamide) (PNIPAM) is a versatile polymer known for its phase transition properties, exhibiting a lower critical solution temperature (LCST) of approximately 32°C. Below this temperature, PNIPAM is hydrophilic, while above it, the polymer becomes hydrophobic, making it ideal for thermosensitive drug delivery systems (DDSs).
