Algorithms for Two Types of Topological Indices

Algorithms
Topological indices are closely related to the stability and physical properties (such as the boiling point) of chemical molecules. The permanental sum and Hosoya index are two topological indices that are strongly associated with molecular structure. In

APROACHING TO HOSOYA INDEX

EPH - International Journal of Biological & Pharmaceutical Science, 2015
Chemistry must not be an Experimental Science, its nature is engineering. For that reason, some methods look for working in a bureau better than in laboratory. Constructing models to get the conversion from Theory and Practice complete is one of the most logic projects everyone is very confident for doing.

Peptide Thioester and Triazole Derivatives Through On‐Resin Dual‐Modification of Peptide Thiosulfonates

Angewandte Chemie International Edition, Volume 65, Issue 38, 14 September 2026.
An on‐resin dual‐modification strategy for peptides is presented, comprising S‐alkynylation of peptide thiosulfonates and regioselective iridium‐catalyzed azide–thioalkyne cycloaddition. This method reliably provides access to peptides with intricate non‐canonical modifications, being compatible with complex peptides, alkynes and azides.

Hosoya Indices of Bicyclic Graphs [PDF]

, 2009
Given a molecular graph G, the Hosoya index Z(G) of G is defined as the total number of the matchings of the graph. Let Bn denote the set of bicyclic graphs on n vertices.

Two Paralogues as They Like It: Conserved and Divergent Evolution of Vertebrate Gcm Genes

Evolution &Development, Volume 28, Issue 3, September 2026.
Comparative overview of Gcm1 and Gcm2 paralogues across vertebrates. Gcm2 is conserved in pharyngeal‐derived organs across gnathostomes, whereas Gcm1 shows lineage‐specific diversification from an ancestral pharyngeal context, including secondary loss in teleosts, distinct expression in bichir gills and skin, and broader expression in mammals ...

Current State of Physical Assessment Education for Newborn and Infant Visits in Public Health Nursing Schools in Japan: A Nationwide Cross‐Sectional Study

Public Health Nursing, Volume 43, Issue 5, Page 1372-1382, September/October 2026.
ABSTRACT Objective Physical assessment by public health nurses is vital for childhood health, but its education remains unclear. This study examines the structure, process, and outcomes of physical assessment education for newborn and infant home visits in public health nursing schools. Design Nationwide cross‐sectional study.

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, Volume 30, Issue 4, Page 523-529, August 2026.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Hosoya and Merrifield-Simmons indices of some classes of corona of two graphs [PDF]

Transactions on Combinatorics, 2012
Let G = (V;E) be a simple graph of order n and size m. An r-matching of G is a set of r edges of G which no two of them have common vertex. The Hosoya index Z(G) of a graph G is defined as the total number of its matchings.

Establishment of an MRI‐Based Diagnostic Approach to Identify Critical Pulpal Inflammation Zones in a Rat Caries‐Derived Pulpitis Model

International Endodontic Journal, Volume 59, Issue 8, Page 1664-1679, August 2026.
ABSTRACT Aim To establish a magnetic resonance imaging (MRI)‐based diagnostic approach for identifying ‘critical pulpal inflammation’ zones in a rat model of caries‐derived pulpitis. Methodology Caries‐derived pulpitis was induced in the molars of Sprague–Dawley rats using the caries‐derived pulpitis model.

Kekulé structures of polyomino chains and the Hosoya index of caterpillar trees [PDF]

, 2012
Let H be a hexagonal chain. Gutman [I. Gutman, Topological properties of benzenoid systems, Theor. Chim. Acta, 45 (1977), 307–315.] proved that there exists a caterpillar tree T(H) such that the number of Kekulé structures of H is equal to the Hosoya ...
