The efficiency of a homology algorithm based on discrete morse theory and coreductions (extended abstract) [PDF]

open access: yes, 2010
Two implementations of a homology algorithm based on the Forman’s discrete Morse theory combined with the coreduction method are presented.

River ice controls permafrost bank erosion across an Arctic delta

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
Massive fields of river ice occupy rivers in the Arctic Coastal Plain, where floodplains are frozen and river banks can rapidly thaw and collapse. We show that river ice accumulations can exacerbate permafrost river bank erosion in infrequently occupied parts of a delta, influencing permafrost thaw and river morphology.

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

open access: yesJournal 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

Counting and Discrete Morse Theory

open access: yesUF Journal of Undergraduate Research, 2019
We examine enumerating discrete Morse functions on graphs up to equivalence by gradient vector fields and by restrictions on the codomain.  We give formulae for the number of discrete Morse functions on specific classes of graphs (line, cycle, and bouquet of circles).

Discrete Morse theory for manifolds with boundary [PDF]

open access: yesTransactions of the American Mathematical Society, 2012
We introduce a version of discrete Morse theory specific for manifolds with boundary. The idea is to consider Morse functions for which all boundary cells are critical. We obtain "Relative Morse Inequalities" relating the homology of the manifold to the number of interior critical cells.

Attention Deficit Hyperactivity Disorder and other neurodevelopmental traits are associated with impact on functioning among children in the general population

open access: yesJCPP Advances, Volume 5, Issue 4, December 2025.
Abstract Background Attention Deficit Hyperactivity Disorder (ADHD) is commonly defined as a categorical diagnosis requiring clinically severe symptoms and impact on functioning. However, ADHD and other neurodevelopmental traits are also distributed continuously in the general population, where their impact on functioning is less clear.

Rigidity and Toledo Invariant for Spin*(8)-Higgs Bundles

open access: yesMathematics
In this paper, we study Spin*(8)-Higgs bundles over compact Riemann surfaces, extending the work of Bradlow, García-Prada, and Gothen on SO*(8). The group Spin*(8) is exceptional among classical real forms, as its complexification Spin(8,C) admits ...
