Discrete Morse theory on graphs

Topology and its Applications, 2009
Discrete Morse theory is originally introduced by R. Forman as a discrete analogue of classical Morse theory to study homotopy properties of finite CW-complexes. In [\textit{R. Ayala}, \textit{L. M. Fernández}, and \textit{J. A. Vilches}, ``Discrete Morse inequalities on infinite graphs'', Electron. J. Comb. 16, No. 1, Research Paper R38, 11p.

A Semi‐Analytical Model for Predicting the Depth‐Averaged Maximum Longitudinal Velocity in Fully Ice‐Covered Confluences

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract At river confluences, the complex hydrodynamics result in significant alterations to flow structures, and the maximum velocity zone serves as one of the primary drivers of pollutant transport and riverbed erosion. This study investigates maximum longitudinal velocity formation in fully ice‐covered confluences, statistically validating the ...

Cohorts of immature Pteropus bats show interannual variation in Hendra virus serology

Journal of Animal Ecology, Volume 95, Issue 3, Page 521-537, March 2026.
Pteropus bat with offspring, photo taken by Manuel Ruiz‐Aravena. Abstract Understanding the drivers of seasonal disease outbreaks remains a fundamental challenge in disease ecology. Periodic outbreaks can be driven by several seasonally varying factors, including pulses of susceptible individuals through births, changes in host behaviour and social ...

The making of novel ecosystems: A process‐based framework for measurement, analysis and application

Methods in Ecology and Evolution, Volume 17, Issue 3, Page 683-704, March 2026.
Abstract Ecological novelty is emerging rapidly due to global change drivers such as climate shifts, species introductions, defaunation, and land‐use transformation. These changes challenge how we assess, understand and manage ecosystems in the Anthropocene.

Combinatorial realization of the Thom-Smale complex via discrete Morse theory [PDF]

, 2010
20 pagesIn the case of smooth manifolds, we use Forman's discrete Morse theory to realize combinatorially any Thom-Smale complex coming from a smooth Morse function by a couple triangulation-discrete Morse function.

Antitrust for the fintech era

American Business Law Journal, Volume 63, Issue 1, Page 57-78, Spring 2026.
Abstract The emerging relationship between fintechs and banks has revealed antitrust's antiquation. At one time, scholars predicted that fintechs could democratize banking while providing a critical source of competition. But then banks began to acquire their digital rivals: about 900 acquisitions of fintechs have taken place since 2021.

Carbonate sedimentology: An evolved discipline

The Depositional Record, Volume 12, Issue 1, February 2026.
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Seventy‐Five Years Underestimating Frequent Events and Other Frequently Underestimated Implications of Langbein's Equation

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract It is seldom realized that whether one uses annual maxima (AM) or partial duration (PD) series for frequency analysis has major implications when predicting the magnitudes and probabilities of smaller, frequently recurring geophysical events.

An approach to calculate Franck-Condon factors involving anharmonic potentials using harmonic oscillator bases

Journal of Physics Communications
In this contribution a discrete variable representation (DVR) approach to calculate Franck-Condon factors (FCFs) is presented. The method is illustrated using a harmonic oscillator basis. The advantage of this approach is that it is possible to calculate
