Convergence and Error Estimates of A Semi-Lagrangian scheme for the Minimum Time Problem
Marianne Akian, Shanqing Liu
We consider a semi-Lagrangian scheme for solving the minimum time problem, with a given target, and the associated eikonal type equation. We first use a discrete time deterministic…
Extending Gromov's optimal systolic inequality
Thomas G. Goodwillie, James J. Hebda, Mikhail G. Katz
The existence of nontrivial cup products or Massey products in the cohomology of a manifold leads to inequalities of systolic type, but in general such inequalities are not optimal…
Retrieval Augmented Zero-Shot Text Classification
Tassallah Abdullahi, Ritambhara Singh, Carsten Eickhoff
Zero-shot text learning enables text classifiers to handle unseen classes efficiently, alleviating the need for task-specific training data. A simple approach often relies on compa…
Low-Step Multi-Commodity Flow Emulators
Bernhard Haeupler, D Ellis Hershkowitz, Jason Li +2
We introduce the concept of low-step multi-commodity flow emulators for any undirected, capacitated graph. At a high level, these emulators contain approximate multi-commodity flow…
Probing the Scalar WIMP-Pion Coupling with the first LUX-ZEPLIN data
J. Aalbers, D. S. Akerib, A. K. Al Musalhi +200
Weakly interacting massive particles (WIMPs) may interact with a virtual pion that is exchanged between nucleons. This interaction channel is important to consider in models where…
21cmSense v2: A modular, open-source 21cm sensitivity calculator
Steven G. Murray, Jonathan Pober, Matthew Kolopanis
The 21cm line of neutral hydrogen is a powerful probe of the high-redshift universe (Cosmic Dawn and the Epoch of Reionization), with an unprecedented potential to inform us about…
