The optical response of bilayer moiré photonic structures can be precisely controlled by varying the lattice geometry. Bilayer crystal slabs exhibit flat bands in band structure, where modes have zero group velocity. They also give rise to momentum-independent light-trapping Bloch waves both transverse and vertical directions, leading high quality-factors ([Formula: see text]) small mode volume...

We report on the Fermi surfaces and superconducting parameters of CaSb$_2$ single crystals (superconducting below $T_{\text{c}}\sim 1.8~\text{K}$) grown by self-flux method. The frequency de-Haas-van-Alphen Shubnikov-de-Haas oscillations evidences a quasi-two-dimensional (quasi-2D) surface, consistent with one forming Dirac lines predicted first-principles calculations. Measurements in state re...

This chapter presents a text-mining-based ontology enhancement and query-processing system. The key ideas introduced here are that of learning and including imprecise concept descriptions into ontology structures. This is essential for ontology-based text information extraction since it is not necessary that text description of the concepts or user-specified descriptions will exactly match stor...

Two studies examined the effects of enhanced text on immediate recognition of drug names. Study 1 sampled 102 college students using a between-subjects design, while Study 2 sampled 11 practicing pharmacists and technicians using a within-subjects Latin square design. Both studies utilized a computer-based sequential recognition task where a prime word was shown with various text enhancements, ...

A novel phenomenon of fluency enhancement via visual gestures of speech in the absence of traditional auditory feedback is reported herein. The effect on visual choral speech on stuttering frequency was investigated. Ten participants who stuttered recited memorized text aloud under two conditions. In a visual choral speech (VCS) condition participants were instructed to focus their gaze on the ...

Text-based geolocation classifiers often operate with a grid-based view of the world. Predicting document location of origin based on text content on a geodesic grid is computationally attractive since many standard methods for supervised document classification carry over unchanged to geolocation in the form of predicting a most probable grid cell for a document. However, the grid-based approa...

With many web sites appearing everyday, it has become increasingly difficult to keep the web directories up-to-date and growing. The interest in the usage of machine learning on automatic text categorization is further stimulated with this intensive growth of World Wide Web. We believe that Web page classification is significantly different from a traditional text classification because of the ...
