Log-Concave Polynomials II: High-Dimensional Walks and an FPRAS for Counting Bases of a Matroid

PROCEEDINGS OF THE 51ST ANNUAL ACM SIGACT SYMPOSIUM ON THEORY OF COMPUTING (STOC '19), pp. 1–12.

By: N. Anari*, K. Liu*, S. Gharan* & C. Vinzant n

author keywords: Approximating Counting; Approximate Sampling; High-Dimensional Expanders; Geometry of Polynomials
TL;DR: It is shown that a high dimensional walk on a weighted simplicial complex mixes rapidly if for every link of the complex, the corresponding localized random walk on the 1-skeleton is a strong spectral expander, and an FPRAS is designed to count the number of bases of any matroid given by an independent set oracle.

Contributors: A. Bressan, M. Mazzola & K. Nguyen

author keywords: sweeping processes; set-valued evolution; controllability
TL;DR: Under suitable assumptions, it is proved that there exists a control function such that the corresponding evolution of the set $\Omega(t)$ is arbitrarily close to the one determined by the sweeping process. (via Semantic Scholar)

An Augmented IB Method & Analysis for Elliptic BVP on Irregular Domains

An Augmented IB Method & Analysis for Elliptic BVP on Irregular Domains. CMES-COMPUTER MODELING IN ENGINEERING & SCIENCES, 119(1), 63–72.

By: Z. Li*, B. Dong, F. Tong & W. Wang

author keywords: Immersed boundary method; augmented approach; convergence; derivative computing
TL;DR: An immersed boundary-augmented method has been developed for linear elliptic boundary value problems on arbitrary domains with a Dirichlet boundary condition that inherits the simplicity, robustness, and first order convergence of the IB method but also provides asymptotic convergence of partial derivatives.

Optimizing the deployment of ultra-low volume and indoor residual spraying for dengue outbreak response

Cavany, S. M., España, G., Lloyd, A. L., Waller, L. A., Kitron, U., Astete, H., … Perkins, T. A. (2019, October 2).

By: S. Cavany*, G. España*, A. Lloyd n, L. Waller*, U. Kitron*, H. Astete*, W. Elson*, G. Vazquez-Prokopec* ...

TL;DR: Although spraying twice each year is likely to avert the most infections, the results indicate that a threshold-based strategy can become an alternative to better balance the translation of spraying effort into impact, particularly if used with a residual insecticide. (via Semantic Scholar)
