Geometry‐Aware Alignment and Comparison of Hierarchical Morse Complexes with Applications

Computer Graphics Forum, EarlyView.
Abstract Scalar fields derived from 3D X‐ray CT scans of samples undergoing ex situ processes, such as thermal aging, chemical etching, or mechanical stress, pose unique challenges for characterizing similarities and differences across acquisitions. Typically, a sample A (source) is imaged, removed, and subjected to experimental conditions that alter ...

Scalable Computation of Topological Abstractions for Scalar Data

Computer Graphics Forum, EarlyView.
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Posthumanism and Cybernetic Art: An Esthetic Exploration of Technology and Human Identity

Sociology Lens, EarlyView.
ABSTRACT Posthumanism is a contemporary intellectual movement that redefines the relationship between humans, technology, biology, and culture. While questioning the traditional humanist perspective that places humans at the center of the universe, it also examines the transformative effects of technology on human identity.

Early Labor Market Outcomes of Young Adults From Same‐Sex Families: Evidence From Population Data

Journal of Marriage and Family, EarlyView.
ABSTRACT Objective This study offers the first population‐based evidence on how young adults from same‐sex families fare when entering the labor market shortly after leaving full‐time education. Background Same‐sex couples' parenting rights remain controversial in many countries.

Financial Climate‐Risk Measurement, Impact Funds, and Green Transitions

Journal of Accounting Research, Volume 64, Issue 4, Page 1867-1903, September 2026.
ABSTRACT Regulators are contemplating or mandating precise measurement of financial climate‐risk exposure to promote sustainable investments. We show that such mandates can be counterproductive in the presence of social funds that catalyze change by subsidizing the adoption of cleaner production technologies.

Hydrogen‐Enhanced Grain Boundary Conductivity Explains High‐Conductivity Anomalies in Trans‐Lithospheric Shear Zones

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Magnetotelluric (MT) surveys reveal high electrical conductivity anomalies along major trans‐lithospheric shear zones. Given that trans‐lithospheric shear zones are proposed conduits for deep‐Earth volatiles, we employ molecular dynamics simulations to quantify H+ diffusivity and electrical conductivity at olivine grain boundaries.

Symmetry‐Restricted Energy Landscapes as a Benchmark for Machine Learned Interatomic Potentials

Advanced Theory and Simulations, Volume 9, Issue 8, August 2026.
We present a benchmark for assessing the physical accuracy of machine‐learned interatomic potentials. By constructing two‐dimensional potential energy surface slices along symmetry‐allowed degrees of freedom and comparing them with DFT, the benchmark reveals model strengths, weaknesses, and artifacts, providing an easily interpretable test of energy ...

Morse Sequences: A Simple Approach to Discrete Morse Theory

Journal of Mathematical Imaging and Vision
In this paper, we develop the notion of a Morse sequence, which provides an alternative approach to discrete Morse theory, and which is both simple and effective. A Morse sequence on a finite simplicial complex is a sequence composed solely of two elementary operations, that is, expansions (the inverse of a collapse), and fillings (the inverse of a ...
