Behind the Noise: Conformal Quantile Regression Reveals Emergent Representations
Petrus H. Zwart, Tamas Varga, Odeta Qafoku +1
Scientific imaging often involves long acquisition times to obtain high-quality data, especially when probing complex, heterogeneous systems. However, reducing acquisition time to…
Advanced Stationary and Non-Stationary Kernel Designs for Domain-Aware Gaussian Processes
Marcus M. Noack, James A. Sethian
Gaussian process regression is a widely-applied method for function approximation and uncertainty quantification. The technique has gained popularity recently in the machine learni…
An Efficient Algorithm for Automatic Structure Optimization in X-ray Standing-Wave Experiments
Osman Karslıoğlu, Mathias Gehlmann, Juliane Müller +5
X-ray standing-wave photoemission experiments involving multilayered samples are emerging as unique probes of the buried interfaces that are ubiquitous in current device and materi…
Characterization of free standing InAs quantum membranes by standing wave hard x-ray photoemission spectroscopy
G. Conti, S. Nemšák, C. -T. Kuo +13
Free-standing nanoribbons of InAs quantum membranes (QMs) transferred onto a (Si/Mo) multilayer mirror substrate are characterized by hard x-ray photoemission spectroscopy (HXPS),…
Jump splicing schemes for elliptic interface problems and the incompressible Navier-Stokes equations
Ben Preskill, James A. Sethian
We present a general framework for accurately evaluating finite difference operators in the presence of known discontinuities across an interface. Using these techniques, we develo…
Nanosurveyor: a framework for real-time data processing
Benedikt J. Daurer, Hari Krishnan, Talita Perciano +4
Scientists are drawn to synchrotrons and accelerator based light sources because of their brightness, coherence and flux. The rate of improvement in brightness and detector technol…
SHARP: a distributed, GPU-based ptychographic solver
Stefano Marchesini, Hari Krishnan, Benedikt J. Daurer +4
Ever brighter light sources, fast parallel detectors, and advances in phase retrieval methods, have made ptychography a practical and popular imaging technique. Compared to previou…
Fast algorithms for optimal control, anisotropic front propagation and multiple arrivals
J. A. Sethian
We review some recent work in fast, efficient and accurate methods to compute viscosity solutions and non-viscosity solutions to static Hamilton-Jacobi equations which arise in opt…
