Interactive floating full-parallax digital three-dimensional light-field display based on wavefront recomposing.

open access: yesOptics Express, 2018
Advanced three-dimensional (3D) imaging techniques can acquire high-resolution 3D biomedical and biological data, but available digital display methods show this data in restricted two dimensions.

Factors impacting the complexity of the leporid intracranial joint

open access: yesJournal of Anatomy, EarlyView.
Anatomy of the intracranial joint and the 2D semi‐landmarks used to capture complexity in the intracranial joint. (a) The intracranial joint can be seen here (in red) between the parietal and occipital dorsally and the basioccipital and basisphenoid ventrally. In hares (as in this figure) the interparietals are fused to obliteration.

Flying fruit flies correct for visual sideslip depending on relative speed of forward optic flow.

open access: yesFrontiers in Behavioral Neuroscience, 2013
As a fly flies through its environment, static objects produce moving images on its retina, and this optic flow is essential for steering and course corrections. Different types of rotation and translation produce unique flow fields, which fly brains are

The HIPPARCOS parallax for Polaris [PDF]

open access: yesAstronomy & Astrophysics, 2013
This letter follows a recent claim that the Hipparcos parallax for Polaris could be too small by 2.5 mas. It examines in detail the Hipparcos epoch astrometric data for Polaris, as well as the viability of other observations that were put forward to support a larger parallax.

Evaluation of the accuracy of digital workflow for implant‐supported full‐arch fixed dental prostheses using a novel micro‐CT measurement technique

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This study aims to evaluate the accuracy of fit of full‐arch implant titanium frameworks fabricated from a fully digital workflow using a novel micro‐CT measurement technique. Materials and Methods A 3D‐printed model with four implant analogs was fabricated.

Analysis of a Very Massive DA White Dwarf via the Trigonometric Parallax and Spectroscopic Methods

open access: yes, 2003
By two different methods, we show that LHS 4033 is an extremely massive white dwarf near its likely upper mass limit for destruction by unstable electron captures.

THE GOULD’S BELT DISTANCES SURVEY (GOBELINS). I. TRIGONOMETRIC PARALLAX DISTANCES AND DEPTH OF THE OPHIUCHUS COMPLEX [PDF]

open access: yes, 2016
We present the first results of the Gould’s Belt Distances Survey (GOBELINS), a project aimed at measuring the proper motion and trigonometric parallax of a large sample of young stars in nearby regions using multi-epoch Very Long Baseline Array (VLBA ...

Enhancing Situational Mastery Experience and Willingness to Learn with Game Elements in Children with Specific Learning Disorders

open access: yesMind, Brain, and Education, EarlyView.
ABSTRACT Children with dyscalculia show less self‐efficacy and more anxiety while engaging in mathematical tasks. In addition to difficulties in basic mathematical skills, such non‐cognitive factors negatively impact their mathematics achievement.

Eye movement parameters for performance evaluation in projection-based stereoscopic display

open access: yesJournal of Eye Movement Research, 2018
The current study applied Structural Equation Modeling (SEM) to analyze the relationship among index of difficulty (ID) and parallax on eye movement time (EMT), fixation duration (FD), time to first fixation (TFF), number of fixation (NF), and eye gaze ...
