Refashion: Reconfigurable Garments via Modular Design
Rebecca Lin, Michal LukáÄ, Mackenzie Leake
While bodies change over time and trends vary, most store-bought clothing comes in fixed sizes and styles and fails to adapt to these changes. Alterations can enable small changes…
The Polygon Burning Problem
William Evans, Rebecca Lin
Motivated by the -center problem in location analysis, we consider the \emph{polygon burning} (PB) problem: Given a polygonal domain with holes and vertices, find a…
Gemini 2.5: Pushing the Frontier with Advanced Reasoning, Multimodality, Long Context, and Next Generation Agentic Capabilities
Gheorghe Comanici, Eric Bieber, Mike Schaekermann +3431
In this report, we introduce the Gemini 2.X model family: Gemini 2.5 Pro and Gemini 2.5 Flash, as well as our earlier Gemini 2.0 Flash and Flash-Lite models. Gemini 2.5 Pro is our…
Graph Threading with Turn Costs
Erik D. Demaine, Yael Kirkpatrick, Rebecca Lin
How should we thread a single string through a set of tubes so that pulling the string taut self-assembles the tubes into a desired graph? While prior work [ITCS 2024] solves this…
Continuous Flattening and Reversing of Convex Polyhedral Linkages
Erik D. Demaine, Martin L. Demaine, Markus Hecher +3
We prove two results about transforming any convex polyhedron, modeled as a linkage L of its edges. First, if we subdivide each edge of L in half, then L can be continuously flatte…
Folding One Polyhedral Metric Graph into Another
Lily Chung, Erik D. Demaine, Martin L. Demaine +4
We analyze the problem of folding one polyhedron, viewed as a metric graph of its edges, into the shape of another, similar to 1D origami. We find such foldings between all pairs o…
The Radio Parallax of the Crab Pulsar: A First VLBI Measurement Calibrated with Giant Pulses
Rebecca Lin, Marten H. van Kerkwijk, Franz Kirsten +2
We use four observations with the European VLBI network to measure the first precise radio parallax of the Crab Pulsar. We found two in-beam extragalactic sources just outside the…
Freeform Islamic Geometric Patterns
Rebecca Lin, Craig S. Kaplan
Islamic geometric patterns are a rich and venerable ornamental tradition. Many classic designs feature periodic arrangements of rosettes: star shapes surrounded by rings of hexagon…
Graph Threading
Erik D. Demaine, Yael Kirkpatrick, Rebecca Lin
Inspired by artistic practices such as beadwork and himmeli, we study the problem of threading a single string through a set of tubes, so that pulling the string forms a desired gr…
High Sensitivity Beamformed Observations of the Crab Pulsar's Radio Emission
Rebecca Lin, Marten H. van Kerkwijk
We analyzed four epochs of beamformed EVN data of the Crab Pulsar at 1658.49 MHz. With the high sensitivity resulting from resolving out the Crab Nebula, we are able to detect even…
Scintillation Properties of PSR B1133+16 Measured with Very Long Baseline Interferometry
Ashley M. Stock, Fardin Syed, Marten H. van Kerkwijk +3
The scintillation of pulsars reveals small-scale structure of the interstellar medium. A powerful technique for characterizing the scintillating structures (screens) combines analy…
Learning Lens Blur Fields
Esther Y. H. Lin, Zhecheng Wang, Rebecca Lin +6
Optical blur is an inherent property of any lens system and is challenging to model in modern cameras because of their complex optical elements. To tackle this challenge, we introd…
Resolving the Emission Regions of the Crab Pulsar's Giant Pulses II. Evidence for Relativistic Motion
Rebecca Lin, Marten H. van Kerkwijk, Robert Main +3
The Crab Pulsar is the prime example of an emitter of giant pulses. These short, very bright pulses are thought to originate near the light cylinder, at from…
Examining Potential Usability and Health Beliefs Among Young Adults Using a Conversational Agent for HPV Vaccine Counseling
Muhammad Amith, Rebecca Lin, Rachel Cunningham +6
The human papillomavirus (HPV) vaccine is the most effective way to prevent HPV-related cancers. Integrating provider vaccine counseling is crucial to improving HPV vaccine complet…
Resolving the emission regions of the Crab pulsar's giant pulses
Robert Main, Rebecca Lin, Marten H. van Kerkwijk +5
The Crab pulsar has striking radio emission properties, with the two dominant pulse components -- the main pulse and the interpulse -- consisting entirely of giant pulses. The emis…
