Gauge fixing for sequence-function relationships

A. Posfai, J. Zhou, D. M. McCandlish, J. B. Kinney

This paper introduces a family of gauges for sequence-function models to remove gauge freedoms and improve model interpretation.

Symmetry, gauge freedoms, and the interpretability of sequence-function relationships

A. Posfai, D. M. McCandlish, J. B. Kinney

This paper analyzes gauge freedoms in sequence-function models and shows their relationship to symmetry and parameter interpretability.

Spatial Ecology of Territorial Populations

B. G. Weiner, A. Posfai, N. S. Wingreen

The paper develops a model of territorial resource competition to study biodiversity and population dynamics, finding that nutrient diffusion time and spatial structure significantly influence species coexistence and extinction.

Selection for protein stability enriches for epistatic interactions

A. Posfai, J. Zhou, J. B. Plotkin, J. B. Kinney, D. M. McCandlish

The paper shows that small non-additive contributions to folding free energy are essential for protein stability, compatible with observed additive mutation effects.
