This work introduces a novel optical 3D sensor principle and its implementation: the ‘single-shot 3D movie camera’. The camera is designed for the 3D measurement of macroscopic objects with scattering surfaces, e.g. human faces. It combines the acquisition of a dense point cloud displaying physically limited lateral resolution and depth...
Massive Black Holes, millions to billions of times more massive than our sun, exist in the centers of most galaxies. However, the formation and evolution of these objects through accretion of gas and mergers with other black holes is still a great mystery. LISA, a future space-based gravitational wave detector,...
A fractal is created by a Piecewise Isometry (PWI) which cuts a 2D object into pieces and rearranges those pieces to recreate the original object in a scrambled form. The PWI studied here splits a hemispherical shell into four pieces along cutting lines and rearranges them into a shuffled hemisphere....
Levitation—the rising or hovering of an object in apparent defiance of gravity—is a captivating phenomenon with a wide range of applications. In this visualization, we demonstrate our newly discovered form of fluid dynamical levitation of small particles that may be 10, 100, or even 1000 times as dense as the...
Firefly is an interactive tool that allows users to fly through any 3 dimensional dataset by rendering it on-the-fly. Here we present simulation data created as part of the FIRE galaxy formation collaboration. Interactively exploring data generates powerful intuition and helps one isolate regions of interest in the data using...
Our research group is currently working to develop the first cross-culturally validated household water insecurity scale. In order to do this, we have partnered with numerous collaborators to implement the survey in diverse ecological settings. As part of the survey, participants are asked to recall how long it takes to...
Psychometric analyses can help illuminate how people approach clinical tests. To understand how health literacy (i.e., literacy for health information) might lead to biased assessment of emotional distress, we examined the psychometric properties of anxiety and depression questionnaires, using differential item functioning (DIF) analysis. Items were flagged for DIF if...
Using ab initio calculations, we discovered a quasi two-dimensional copper–bismuth nano sheet, which we call cubine. According to our predictions, single layers of cubine can be isolated from the recently reported high-pressure CuBi bulk material at an extremely low energetic cost, comparable to values to separate single layers of graphene...
The ideology scores of US Congress members over time, quantified from how similarly they voted on bills. I present an interactive visualization for the US Congress members’ ideology. The data used are ideology scores of US Congress members 1789-2015. The ideology scores are quantified from the Congress members’ voting records...
Objectives: Poor infant health is associated with lower wellbeing later in life. Food insecurity has been associated with higher rates of some morbidities in young children. However, this relationship has not been well studied in infants younger than six months or in Kenya. Thus, we sought to determine the relationship...
