Characterizing some major Archean faults at depth in the Superior craton, North America Open
The geometry of ancient (2.75–2.65 Ga) faults at depth can only be mapped in detail by high-resolution geophysical surveys such as seismic reflection profiling. Recent deep (35–48 km) reflection profiles acquired throughout the Archean sou…

Guiding Data Collection via Factored Scaling Curves Open
Generalist imitation learning policies trained on large datasets show great promise for solving diverse manipulation tasks. However, to ensure generalization to different conditions, policies need to be trained with data collected across a…

Constraints on Growth and Stabilization of the Western Superior Craton From Inversion of Magnetotelluric Data Open
A data set consisting of 376 broadband and long‐period MT measurements was used to generate the first ever 3D resistivity model of the Archean western Superior Craton. The modeled resistivity structure is compared to coincident seismic ref…

A North Caribou superterrane in the Superior craton, North America Open
Geologists broadly understand the 3-D building of Earth's continents, but much less so the construction of their ancient, Archean nuclei, the cratons. Definition of terranes that play a pivotal role in reconstructions of Archean tectonic h…

Online Learning for Obstacle Avoidance Open
We approach the fundamental problem of obstacle avoidance for robotic systems via the lens of online learning. In contrast to prior work that either assumes worst-case realizations of uncertainty in the environment or a stationary stochast…

A study of faults in the Superior province of Ontario and Quebec using the random forest machine learning algorithm: Spatial relationship to gold mines Open
This paper uses the random forest (RF) algorithm to produce two maps of orogenic gold prospectivity (MPM) across the entire Superior geologic province of Ontario and Quebec, Canada. One MPM of this entire study area is based on a compilati…

EXTH-53. IL-12 ARMORED CAR T CELL THERAPY FOR HETEROGENEOUS GLIOBLASTOMA Open
INTRODUCTION Chimeric antigen receptor (CAR) T cells specific for the glioblastoma (GBM)-specific epidermal growth factor receptor variant III (EGFRvIII; CARvIII) have successfully treated tumors homogeneously expressing EGFRvIII when comb…

The implications of crustal architecture and transcrustal upflow zones on the metal endowment of a world-class mineral district Open
Earth’s mineral deposits show a non-uniform spatial distribution from the craton-scale, to the scale of individual mineral districts. Although this pattern of differential metal endowment is underpinned by lithospheric-scale processes the …

Aggressive mimicry by the juvenile of the redmouth grouper, Aethaloperca rogaa (Serranidae) Open
The juvenile of the Redmouth Grouper, Aethaloperca rogaa (Forsskål, 1775), which is colored differently than the adult, closely resembles several small, non predatory reef fishes (Centropyge spp., Pomacentrus spp., and Stegastes spp.). We …

Design of a Novel Online, Modular, Flipped-classroom Surgical Curriculum for East, Central, and Southern Africa Open
Objective: We describe a structured approach to developing a standardized curriculum for surgical trainees in East, Central, and Southern Africa (ECSA). Summary Background Data: Surgical education is essential to closing the surgical acces…

Failure Prediction with Statistical Guarantees for Vision-Based Robot Control Open
We are motivated by the problem of performing failure prediction for safety-critical robotic systems with high-dimensional sensor observations (e.g., vision). Given access to a black-box control policy (e.g., in the form of a neural networ…

On Archean craton growth and stabilisation: Insights from lithospheric resistivity structure of the Superior Province Open
The nature of lithospheric evolution and style of the driving tectonic processes during the growth and stabilisation of continental crust in the Archean remain enigmatic. The hotter, rheologically weak Archean crust would be unable to supp…
