VisTellAR: Embedding Data Visualization to Short-form Videos Using Mobile Augmented Reality.

With the rise of short-form video platforms and the increasing availability of data, we see the potential for people to share short-form videos embedded with data in situ (e.g., daily steps when running) to increase the credibility and expressiveness of their stories.

VisTA-LIVE: A Visualization Tool for Assessment of Laboratories in Virtual Environments.

A Virtual Reality Laboratory (VR Lab) experiment refers to an experiment session that is being conducted in the virtual environment through Virtual Reality (VR) and aims to deliver procedural knowledge to students similar to that in a physical lab environment. While VR Lab is becoming more popular among education institutes as a learning tool for students, existing designs are mostly considered from a student's perspective. Instructors could only receive limited information on how the students are performing and could not provide useful feedback to aid the students' learning and evaluate their performance.

Electrophysiological mapping of the epicardium via 3D-printed flexible arrays.

Cardiac electrophysiology mapping and ablation are widely used to treat heart rhythm disorders such as atrial fibrillation (AF) and ventricular tachycardia (VT). Here, we describe an approach for rapid production of three dimensional (3D)-printed mapping devices derived from magnetic resonance imaging. The mapping devices are equipped with flexible electronic arrays that are shaped to match the epicardial contours of the atria and ventricle and allow for epicardial electrical mapping procedures.

A Modified 4Ts Score for Heparin-Induced Thrombocytopenia in the Mechanical Circulatory Support Population.

Objective: To identify risk factors and develop a pretest scoring system to differentiate patients with heparin-induced thrombocytopenia (HIT) in the mechanical circulatory support (MCS) population. The authors present a modified "4T" scoring system, which considers the "type of mechanical circulatory support" that may help identify patients at risk for developing postoperative HIT.

Design: A retrospective cohort study.

High-resolution spatiotemporal changes in dominant frequency and structural organization during persistent atrial fibrillation.

Objective: Analyze changes in frequency activity and structural organization that occur over time with persistent atrial fibrillation (AF).

Background: Little is known about the frequency characteristics of the epicardium during transition from paroxysmal to persistent AF. Accurate identification of areas of high dominant frequency (DF) is often hampered by limited spatial resolution.
