Using Gemini and LuaLaTeX to transcribe physics videos into PDF/UA-2 and ISO 32005 math-accessible PDFs

Craig W. Looney, Christopher L. Duston

We present an AI transcription workflow that uses freely available tools to transcribe instructional physics videos with substantial mathematical content into math-accessible PDFs.…

Size, shape, density, and atmospheric limit of (50000) Quaoar revealed from 14 years of stellar occultation

Giuliano Margoti, Felipe Braga-Ribas, José Luis Ortiz +173

We present results from 28 stellar occultations by the large Trans-Neptunian Object (50000) Quaoar registered between 2018 and 2025. By performing a joint analysis of this occultat…

The 2017 Merrimack College Mobile Lightboard: Personalized Office-Based Lightboarding on a Shared Mobile Board

Craig W. Looney, Christopher L. Duston, James H. Biegel +2

We present and evaluate the Merrimack College Mobile Lightboard, which we built in 2017 and which is still in use in 2025. Our design was closely based on that of the groundbreakin…

The Realization of 3D Topological Spaces Branched Over Graphs

Christopher L Duston

In this paper we present an implementation of a computer algorithm that automatically determines the topological structure of spacetime, using a branched covering space representat…

Metrics on End-Periodic Manifolds as Models for Dark Matter

Christopher L Duston

In this paper we will detail an approach to generate metrics and matter models on end-periodic manifolds, which are used extensively in the study of the exotic smooth structures of…

Torus Solutions to the Weierstrass-Enneper Representation of Surfaces

Christopher Levi Duston

In this paper we present a torus solution to the generalized Weierstrass-Enneper representation of surfaces in . The key analytical technique will be Bloch wave funct…

Cosmic Strings in Conformal Gravity

Reinoud Jan Slagter

We investigate the spacetime of a spinning cosmic string in conformal invariant gravity, where the interior consists of a gauged scalar field. We find exact solutions of the exteri…

Using Cosmic Strings to Relate Local Geometry to Spatial Topology

Christopher L. Duston

In this paper we will discuss how cosmic strings can be used to bridge the gap between the local geometry of our spacetime model and the global topology. The primary tool is the th…

The Fundamental Group of a Spatial Section Represented by a Topspin Network

Christopher L Duston

We present an algorithm which determines the fundamental group of a spatial section using topspin networks. Tracking the topology of the spatial section is a unique feature of this…

Semiclassical Partition Functions for Gravity with Cosmic Strings

Christopher L. Duston

In this paper we describe an approach to construct semiclassical partition functions in gravity which are complete in the sense that they contain a complete description of the diff…

Topspin Networks in Loop Quantum Gravity

Christopher L. Duston

We discuss the extension of loop quantum gravity to topspin networks, a proposal which allows topological information to be encoded in spin networks. We will show that this require…

Exotic Smoothness in Four Dimensions and Euclidean Quantum Gravity

Christopher L Duston

In this paper we calculate the effect of the inclusion of exotic smooth structures on typical observables in Euclidean quantum gravity. We do this in the semiclassical regime for s…
