Autonomous search for a diffusive source in an unknown environment

Branko Ristic, Alex Skvortsov, Andrew Walker

The paper presents an approach to olfactory search for a diffusive emitting source of tracer (e.g. aerosol, gas) in an environment with unknown map of randomly placed and shaped ob…

The Differential Rotation of Kappa1 Ceti as Observed by MOST

Gordon A. H. Walker, Bryce Croll, Rainer Kuschnig +7

We first reported evidence for differential rotation of Kappa1 Ceti in Paper I. In this paper we demonstrate that the differential rotation pattern closely matches that for the Sun…

PLUTO-4: Frontier Pathology Foundation Models

Harshith Padigela, Shima Nofallah, Atchuth Naveen Chilaparasetti +11

Foundation models trained on large-scale pathology image corpora have demonstrated strong transfer capabilities across diverse histopathology tasks. Building on this progress, we i…

Looking for Giant Earths in the HD 209458 System: A Search for Transits in MOST Space-based Photometry

Bryce Croll, Jaymie M. Matthews, Jason F. Rowe +11

We have made a comprehensive transit search for exoplanets down to about 2 Earth radii in the HD 209458 system, based on nearly uninterrupted broadband optical photometry obtained…

Magnetoresistive RAM for error resilient XNOR-Nets

Michail Tzoufras, Marcin Gajek, Andrew Walker

We trained three Binarized Convolutional Neural Network architectures (LeNet-4, Network-In-Network, AlexNet) on a variety of datasets (MNIST, CIFAR-10, CIFAR-100, extended SVHN, Im…

The role of multistability and transient trajectories in networked dynamical systems: Connectomic dynamics of C. elegans and behavioral assays

James Kunert, Eli Shlizerman, Andrew Walker +1

The neural dynamics of the nematode C. elegans are experimentally low-dimensional and correspond to discrete behavioral states, where previous modeling work has found neural proxie…
