Private Broadcasting over Independent Parallel Channels
Ashish Khisti, Tie Liu
We study private broadcasting of two messages to two groups of receivers over independent parallel channels. One group consists of an arbitrary number of receivers interested in a…
Gaussian Process Regression with Heteroscedastic or Non-Gaussian Residuals
Chunyi Wang, Radford M. Neal
Gaussian Process (GP) regression models typically assume that residuals are Gaussian and have the same variance for all observations. However, applications with input-dependent noi…
Spin-state transition in the Fe-pnictides
H. Gretarsson, S. R. Saha, T. Drye +7
We report a Fe Kβx-ray emission spectroscopy study of local magnetic moments in the rare-earth doped iron pnictide Ca_{1-x}RE_xFe_2As_2 (RE=La, Pr, and Nd). In all samples studied…
The Bayesian process control with multiple assignable causes
Jue Wang, Chi-Guhn Lee
We study an optimal process control problem with multiple assignable causes. The process is initially in-control but is subject to random transition to one of multiple out-of-contr…
Cyclic sieving, rotation, and geometric representation theory
Bruce Fontaine, Joel Kamnitzer
We study rotation of invariant vectors in tensor products of minuscule representations. We define a combinatorial notion of rotation of minuscule Littelmann paths. Using affine Gra…
Robo-AO: An Autonomous Laser Adaptive Optics and Science System
Christoph Baranec, Reed Riddle, A. N. Ramaprakash +15
Robo-AO, a fully autonomous, laser guide star adaptive optics and science system, is being commissioned at Palomar Observatory's 60-inch telescope. Here we discuss the instrument,…
