Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration
Advanced Functional Materials, EarlyView.Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.

An Overview of Techniques for Cardiac Left Ventricle Segmentation on Short-Axis MRI
ITM Web of Conferences, 2016 Nowadays, heart diseases are the leading cause of death. Left ventricle segmentation of a human heart in magnetic resonance images (MRI) is a crucial step in both cardiac diseases diagnostics and heart internal structure reconstruction.

Long-term outcome after tricuspid valvectomy in a neonate with Candida endocarditis : a case report [PDF]
, 2019 Tricuspid valvectomy is a rare surgical intervention, and knowledge regarding long-term outcome in children is lacking. We report a favourable outcome 11 years after tricuspid valvectomy in early infancy without subsequent surgery or other cardiac ...

Advanced Functional Materials, EarlyView.Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.
