Age-Optimal Causal Labeling of Memoryless Processes

Emre Telatar, Yunus Inan

We consider a problem of labeling a memoryless temporal point process. The labelings have to be done causally. We study the tradeoff between the rate and age of the labeled process and characterize the optimal tradeoff curve. We show that the optimal curve ...

Shake table testing of aggregate masonry buildings

Katrin Beyer, Igor Tomic

Masonry building aggregates can be found throughout historical city centers of Europe. Adjacent buildings have often developed during the long densification process, without consistent planning or engineering. It is common for neighboring units to share a ...

Max-infinitely divisible models and inference for spatial extremes

Raphaël Huser, Emeric Rolland Georges Thibaud

For many environmental processes, recent studies have shown that the dependence strength is decreasing when quantile levels increase. This implies that the popular max-stable models are inadequate to capture the rate of joint tail decay, and to estimate jo ...

The Homotopy Theory Of Coalgebras Over Simplicial Comonads

Kathryn Hess Bellwald, Magdalena Kedziorek

We apply the Acyclicity Theorem of Hess, Kedziorek, Riehl, and Shipley (recently corrected by Garner, Kedziorek, and Riehl) to establishing the existence of model category structure on categories of coalgebras over comonads arising from simplicial adjuncti ...

Practical Intramolecular Symmetry Adapted Perturbation Theory via Hartree-Fock Embedding

Anne-Clémence Corminboeuf, Jérôme Florian Gonthier

We develop a simple methodology for the computation of symmetry-adapted perturbation theory (SAPT) interaction energy contributions for intramolecular noncovalent interactions. In this approach, the local occupied orbitals of the total Hartree-Fock (HF) wa ...
