Cayley–Menger curvature: a geometric approach to discrete curvature on graphs via local simplex embedding

David Sierra Porta

Abstract We introduce a discrete curvature measure for graphs based on the Cayley–Menger determinant, which we term Cayley–Menger curvature ($ \symbf{\kappa_{\textbf{CM}}} $). For each node, we construct local tetrahedra from its nearest neighbors under the effective resistance metric, compute the Cayley–Menger determi...

Thermodynamic Insights into Isoniazid Solubility in PEG 300 + Water Mixtures

Pedro Nel Martinez Romero · Nestor Enrique Cerquera · Rossember Edén Cardenas-Torres · Fleming Martinez · y 1 más

Solubility studies are essential for developing more efficient dosing processes and systems. The solubility of INH in a mixture of PEG 300 (1) + water (2) was evaluated at various temperatures using UV/Vis spectrophotometry and the shaking flask method. Solubility increased by 150% at 288.15 K and 298% at 318.15 K, ref...
