On Extractors and Exposure-Resilient Functions for Sublogarithmic Entropy
(Wiley-Blackwell, 2013)
We study resilient functions and exposure-resilient functions in the low-entropy regime. A resilient function (a.k.a. deterministic extractor for oblivious bit-fixing sources) maps any distribution on n -bit strings in ...
Generalized Random Utility Models with Multiple Types
(Neural Information Processing Systems Foundation, Inc., 2013)
We propose a model for demand estimation in multi-agent, differentiated product settings and present an estimation algorithm that uses reversible jump MCMC techniques to classify agents' types. Our model extends the popular ...
Discrete One-forms on Meshes and Applications to 3D mesh Parameterization
(Elsevier, 2006)
We describe how some simple properties of discrete one-forms directly relate to some old and new results concerning the parameterization of 3D mesh data. Our first result is an easy proof of Tutte's celebrated “spring-embedding” ...
Size limits of self-assembled colloidal structures made using specific interactions
(Proceedings of the National Academy of Sciences, 2014)
We establish size limitations for assembling structures of controlled size and shape out of colloidal particles with short-ranged interactions. Through simulations we show that structures with highly variable shapes made ...
Universal frequency-dependent conduction of electron glasses
(IOP Publishing, 2014)
Characterizing the frequency-dependent response of amorphous systems and glasses can provide important insights into their physics. Here, we study the response of an electron glass, where Coulomb interactions are important ...
Getting into shape: How do rod-like bacteria control their geometry?
(Springer Science + Business Media, 2014)
Rod-like bacteria maintain their cylindrical shapes with remarkable precision during growth. However, they are also capable to adapt their shapes to external forces and constraints, for example by growing into narrow or ...
Cell Size Regulation in Bacteria
(American Physical Society (APS), 2014)
Various bacteria such as the canonical gram negative Escherichia coli or the well-studied gram positive Bacillus subtilis divide symmetrically after they approximately double their volume. Their size at division is not ...
