On the maximum atom-bond sum-connectivity index of molecular trees
AKCE International Journal of Graphs and CombinatoricsLet G be a graph with V(G) and E(G), as vertex set and edge set, respectively. The atom-bond sum-connectivity (ABS) index is a vertex-based topological index which is defined as [Formula: see text] where [Formula: see text] is the degree of the vertex a.

Beyond Primary Nucleation: Molecular Basis of Peptide Crystal Secondary Nucleation at Soft Interface
Advanced Functional Materials, EarlyView.High spatiotemporal‐resolution atomic force microscopy directly resolved peptide secondary nucleation (SN) and growth characteristics and mechanisms on HOPG. The landscape of peptide nucleation sites, growth dynamics, molecular‐scale structures, phase transitions, and cross‐seeding processes were realized.

Some Vertex/Edge-Degree-Based Topological Indices of r-Apex Trees
, 2021 In chemical graph theory, graph invariants are usually referred to as topological indices. For a graph G, its vertex-degree-based topological indices of the form BIDG=∑uv∈EGβdu,dv are known as bond incident degree indices, where EG is the edge set of G ...

Spanning Trees whose Stems have a Bounded Number of Branch Vertices
Discussiones Mathematicae Graph Theory, 2016 Let T be a tree, a vertex of degree one and a vertex of degree at least three is called a leaf and a branch vertex, respectively. The set of leaves of T is denoted by Leaf(T).

Degree conditions for vertex switching reconstruction
Discrete Mathematics, 1996 This paper is related to the \(s\)-vertex switching reconstruction problem. If \(G= G(V,E)\) is a graph and \(U \subset V\), the switching \(G_U\) of \(G\) is the graph obtained from \(G\) by replacing all the edges between \(U\) and \(V \backslash U\) with the nonedges.

Advanced Healthcare Materials, EarlyView.CCL22‐releasing PLGA microparticles (MP) suspended in topically applied hydrogels (HEART) establish a sustained chemokine gradient at the injured myocardium. HEART recruits CCR4+ regulatory T cells, reduces infarct size and graft fibrosis, and improves cardiac function.

Vertex-degree-based topological indices over trees with two branching vertices
, 2019 : Given a graph G with n vertices, a vertex-degree-based topological index is defined from a set of real numbers {φij} as T I (G) = Pmij (G) φij , where mij (G) is the number of edges between vertices of degree i and degree j, and the sum runs over all 1

Hemocompatible Glycogen‐Tissue Plasminogen Activator Complexes for Enhanced Blood Clot Dissolution
Advanced Healthcare Materials, EarlyView.Glycogen–heparin‐cRGD nanoparticles enable targeted delivery of tissue plasminogen activator (tPA) to thrombi through activated platelet recognition. The hemocompatible hybrids minimize interactions with blood and immune cells while retaining enzymatic biodegradability.
