Testing Biased Randomization Assumptions and Quantifying Imperfect Matching and Residual Confounding in Matched Observational Studies [PDF]
One central goal of design of observational studies is to embed non-experimental data into an approximate randomized controlled trial using statistical matching. Despite empirical researchers' best intention and effort to create high-quality matched samples, residual imbalance due to observed covariates not being well matched often persists.

Optical Hemodynamic Imaging of Jugular Venous Dynamics During Altered Central Venous Pressure [PDF]
Objective: An optical imaging system is proposed for quantitatively assessing jugular venous response to altered central venous pressure. Methods: The proposed system assesses sub-surface optical absorption changes from jugular venous waveforms with a

A Novel Sample-efficient Deep Reinforcement Learning with Episodic Policy Transfer for PID-Based Control in Cardiac Catheterization Robots [PDF]
Robotic catheterization is typically used for percutaneous coronary intervention procedures nowadays and it involves steering flexible endovascular tools to open up occlusion in the coronaries. In this study, a sample-efficient deep reinforcement learning with episodic policy transfer is, for the first time, used for motion control during robotic ...
