VIV Excitation Competition Between Bare and Buoyant Segments of Flexible Cylinders [PDF]

, 2013
This paper addresses a practical problem: “Under which coverage of buoyancy modules, would the Vortex Induced Vibration (VIV) excitation on buoyant segments dominate the response?” This paper explores the excitation competition between bare and buoyant ...

Integration of Redox‐Active Polyoxovanadate Clusters into PMMA: Structure, Nanoscale Organization and Multilevel Redox Switching

Advanced Electronic Materials, EarlyView.
Solvent‐processable polyoxovanadate–PMMA nanocomposites exhibit concentration‐dependent 2D and 3D organization on gold surfaces, while retaining multilevel redox switching at room temperature. These hybrids bridge nanoscale functionality and macroscopic measurement, establishing a versatile platform for hybrid molecular–polymer memory materials ...

Estimation of the Damping Parameter Governing the VIV of Long Flexible Cylinders [PDF]

, 2015
Much effort in the past half century has been made to explain the role of damping in the prediction of VIV. Scruton (1965), Griffin et al. (1975), Klamo, et al. (2005) and Govardhan & Williamson (2006) all made significant contributions.

HOPE Kids 2: Phase 3, Randomized Trial of Voxelotor in Children With SCD and Conditional Cerebral Blood Flow Velocities

American Journal of Hematology, EarlyView.
ABSTRACT Children with SCD have elevated stroke risk, correlated with cerebral blood flow velocity (CBFV). HOPE Kids 2 was a phase 3, multicenter, double‐blind, placebo‐controlled trial evaluating the effect of voxelotor on CBFV. Participants aged 2 to < 15 years with SCD (HbSS/HbSβ0) and conditional CBFV (170 to < 200 cm/s) were randomized 1:1 to ...

Heterozygous Variants in LRP1 Cause a Neurodevelopmental Disorder With Congenital Heart Defects

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT LRP1 encodes the low‐density lipoprotein (LDL) receptor‐related protein 1 (LRP1), a transmembrane protein involved in endocytosis and activation of multiple signaling pathways. LRP1 variants have been implicated in the pathogenesis of congenital heart defects (CHD), Alzheimer's disease, and neurodevelopmental disorders (NDD).

Meta‐Analysis of Stroke and Mortality Rates in Patients Undergoing Valve‐in‐Valve Transcatheter Aortic Valve Replacement

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background During the past decade, the use of transcatheter aortic valve replacement (TAVR) was extended beyond treatment‐naïve patients and implemented for treatment of degenerated surgical bioprosthetic valves.
