Transitive Decompositions of Graphs and Their Links with Geometry and Origami [PDF]

The American Mathematical Monthly, 2010
A transitive decomposition of a graph is a partition of the edge or arc set giving a set of subgraphs which are preserved and permuted transitively by a group of automorphisms of the graph. In this paper we give some background to the study of transitive decompositions and highlight a connection with partial linear spaces.

Diiodido{2-(morpholin-4-yl)-N-[1-(2-pyridyl)ethylidene]ethanamine-κ3N,N′,N′′}zinc

Acta Crystallographica Section E, 2011
In the title compound, [ZnI2(C13H19N3O)], the ZnII ion is five-coordinated in a distorted square-pyramidal geometry, in which the basal plane is defined by three N atoms from the Schiff base ligand and one iodide ion.

Bis(μ2-quinoline-2-carboxylato)-κ3N,O1:O1;κ3O1:N,O1-bis[(acetato-κO)(ethanol-κO)lead(II)]

Acta Crystallographica Section E, 2011
In the centrosymmetric dinuclear title compound, [Pb2(C10H6NO2)2(CH3COO)2(C2H5OH)2], one O atom of the carboxylate group of the quinoline-2-carboxylate anion connects the two PbII atoms.

2-(5-Bromo-2-methylphenyl)propan-2-ol

Acta Crystallographica Section E, 2010
The title compound, C10H13BrO, crystallizes with four independent molecules of similar geometry in the asymmetric unit. The crystal packing is stabilized by intermolecular O—H...O hydrogen bonds, which link the molecules into tetramers.

Purcell’s Three-Link Swimmer: Assessment of Geometry and Gaits for Optimal Displacement and Efficiency

Mathematics, 2021
This paper studies the displacement and efficiency of a Purcell’s three-link microswimmer in low Reynolds number regime, capable of moving by the implementation of a motion primitive or gait.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
