Advanced Photonics Research, EarlyView.Photonic resonances within a dielectric metasurface are investigated using photoelectron emission microscopy (PEEM) and finite‐difference time‐domain simulations. An electron inelastic mean free path of 35 ± 10 nm is extracted from comparisons between microscopy and simulations.

E3Solver: decision tree unification by enumeration [PDF]
arXiv, 2017 We introduce E3Solver, a unification-based solver for programming-by-example (PBE) participating in the 2017 edition of the SyGuS Competition. Our tool proceeds in two phases. First, for each individual example, we enumerate a terminal expression consistent with it. Then, we unify these expressions using conditional expressions in a decision tree.

Spherical and Aspherical Lenses for Boosting the Performance of Terahertz Imaging Systems
Advanced Photonics Research, EarlyView.This study investigates the enhancement of terahertz (THz) detection through the terajet effect using mesoscale dielectric lenses of various geometries. Spherical, aspherical, and cubic polytetrafluoroethylene lenses are evaluated at 0.15 and 0.3 THz, demonstrating significant improvements in responsivity and noise reduction.

Anatomical Sciences Education, Volume 16, Issue 1, Page 128-147, January/February 2023., 2023 Abstract Uncertainty tolerance, individuals' perceptions/responses to uncertain stimuli, is increasingly recognized as critical to effective healthcare practice. While the Covid‐19 pandemic generated collective uncertainty, healthcare‐related uncertainty is omnipresent.

Learning Optimal Decision Trees from Large Datasets [PDF]
arXiv, 2019 Inferring a decision tree from a given dataset is one of the classic problems in machine learning. This problem consists of buildings, from a labelled dataset, a tree such that each node corresponds to a class and a path between the tree root and a leaf corresponds to a conjunction of features to be satisfied in this class.

Advanced Theory and Simulations, EarlyView.Analytic morphing of wurtzite nanowire cross sections to arbitrary shapes yields numbers of nanowire atoms, of bonds between these and of nanowire interface bonds, plus the nanowire cross section area. The ratios of above variables help to interpret any spectroscopic nanowire data which depend on diameter and cross section shape, and can be applied to ...

Crystal Structure Prediction of Cs–Te with Supervised Machine Learning
Advanced Theory and Simulations, EarlyView.High‐throughput density functional theory calculations combined with machine learning models are employed to predict stable Cs– Te binary crystals. By systematically evaluating various structural descriptors and learning algorithms, the superiority of models based on atomic coordination environments is revealed.
