Lower loop re‐entrant flutter [PDF]
Journal of ArrhythmiaAn elderly man with a history of a prior inferior wall myocardial infarction underwent ablation for an atypical right atrial flutter. Electroanatomic mapping revealed diffuse scarring on the anterior, anterolateral, and posterior right atrium, presumably due to atrial infarction from the prior inferior wall myocardial infarction, forcing the activation

Droplet impact on doubly re-entrant structures [PDF]
Scientific ReportsDoubly re-entrant pillars have been demonstrated to possess superior static and dynamic liquid repellency against highly wettable liquids compared to straight or re-entrant pillars.

Re‐Entrant Super‐Repellent Metallic Structures for Robust Anti‐Icing [PDF]
Advanced ScienceSuperhydrophobic surfaces exhibit significant potential for anti‐icing applications. However, sustaining the superhydrophobic Cassie‐Baxter state under conditions of low temperature, high humidity, and dynamic impacts remains a critical challenge.

Impact Response of Re-Entrant Hierarchical Honeycomb. [PDF]
Materials (Basel), 2023 Here, hexagonal and triangular lattices are layered and merged into a re-entrant honeycomb to replace each cell wall of the re-entrant honeycomb. In order to study the crushing behavior of the new variable-angle-variable-substructure-number-gradient honeycomb, a finite element analysis of in-plane and out-of-plane crushing was carried out.

Mechanical Properties of Re-Entrant Hybrid Honeycomb Structures for Morphing Wings [PDF]
BiomimeticsThe exceptional energy absorption, deformability, and tuneable Poisson’s ratio properties of negative Poisson’s ratio (NPR) honeycomb biomimetic structures make them highly suitable for applications in aerospace, medical, and acoustic stealth industries.

In-Plane Compressive Responses of Non-Homogenous Re-Entrant Honeycombs Fabricated by Fused Deposition Modelling [PDF]
MicromachinesAuxetic structures, with re-entrant (inverted hexagonal or bow tie) unit cells, have received considerable interest due to their negative Poisson’s ratio property that results in superior mechanical properties.

Intra-atrial Re-entrant Tachycardia
Indian Pacing and Electrophysiology Journal, 2003 A 15-year-old girl, previously asymptomatic for palpitations, underwent a successful atrial septal defect (ASD) device closure. Twelve weeks after the procedure, the patient was admitted complaining of dyspnoea on effort and palpitations.

Re-entrant ferroelectricity in liquid crystals [PDF]
, 2000 The ferroelectric (Sm C$^*$) -- antiferroelectric (Sm C$^*_A$) -- reentrant ferroelectric (re Sm C$^*$) phase temperature sequence was observed for system with competing synclinic - anticlinic interactions.
