[HTML][HTML] Perspective: Sloppiness and emergent theories in physics, biology, and beyond

MK Transtrum, BB Machta, KS Brown… - The Journal of …, 2015 - pubs.aip.org
Large scale models of physical phenomena demand the development of new statistical and
computational tools in order to be effective. Many such models are “sloppy,” ie, exhibit …

[HTML][HTML] Correlation functions quantify super-resolution images and estimate apparent clustering due to over-counting

SL Veatch, BB Machta, SA Shelby, EN Chiang… - PloS one, 2012 - journals.plos.org
We present an analytical method using correlation functions to quantify clustering in super-resolution
fluorescence localization images and electron microscopy images of static surfaces …

Parameter space compression underlies emergent theories and predictive models

BB Machta, R Chachra, MK Transtrum, JP Sethna - Science, 2013 - science.org
The microscopically complicated real world exhibits behavior that often yields to simple yet
quantitatively accurate descriptions. Predictions are possible despite large uncertainties in …

Information geometry for multiparameter models: New perspectives on the origin of simplicity

…, MC Abbott, MK Transtrum, BB Machta… - Reports on Progress …, 2022 - iopscience.iop.org
Complex models in physics, biology, economics, and engineering are often ill-determined or
sloppy: their multiple parameters can vary over wide ranges without significant changes in …

Geometry of nonlinear least squares with applications to sloppy models and optimization

MK Transtrum, BB Machta, JP Sethna - Physical Review E, 2011 - APS
Parameter estimation by nonlinear least-squares minimization is a common problem that
has an elegant geometric interpretation: the possible parameter values of a model induce a …

Why are nonlinear fits to data so challenging?

MK Transtrum, BB Machta, JP Sethna - Physical review letters, 2010 - APS
Fitting model parameters to experimental data is a common yet often challenging task,
especially if the model contains many parameters. Typically, algorithms get lost in regions of …

[PDF][PDF] Minimal model of plasma membrane heterogeneity requires coupling cortical actin to criticality

BB Machta, S Papanikolaou, JP Sethna, SL Veatch - Biophysical journal, 2011 - cell.com
We present a minimal model of plasma membrane heterogeneity that combines criticality
with connectivity to cortical cytoskeleton. The development of this model was motivated by …

[HTML][HTML] Mechanical surface waves accompany action potential propagation

A El Hady, BB Machta - Nature communications, 2015 - nature.com
Many diverse studies have shown that a mechanical displacement of the axonal membrane
accompanies the electrical pulse defining the action potential (AP). We present a model for …

Escherichia coli chemotaxis is information limited

HH Mattingly, K Kamino, BB Machta, T Emonet - Nature physics, 2021 - nature.com
… In all panels, the shading and error bars indicate ±1 se b, Chemotactic performance v d
as a … Black and grey dots are data points from b plotted against \(\dot I_{s \to a}\)(g) = βg 2 . …

Critical Casimir forces in cellular membranes

BB Machta, SL Veatch, JP Sethna - Physical review letters, 2012 - APS
Recent experiments suggest that membranes of living cells are tuned close to a miscibility
critical point in the two-dimensional Ising universality class. We propose that one role for this …
