By: L. Goel n, H. Wu n, B. Zhang n , J. Kim n, P. Dayton n, Z. Xu *, X. Jiang n

author keywords: Intravascular sonothrombolysis; Safety; Retracted clots; Nanodroplets; Microbubbles; Ultrasound-assisted thrombolysis; Tissue plasminogen activator
MeSH headings : Animals; Microbubbles; Particle Size; Thrombolytic Therapy; Thrombosis / therapy; Tissue Plasminogen Activator; Transducers; Ultrasonic Therapy
TL;DR: In vitro and ex vivo tests using FVI transducers revealed a temperature rise of less than 1°C, no vessel damage as assessed by histology and no downstream clot particles >500 µm, which indicates that the F VI transducer poses minimal risk for sonothrombolysis applications and should be further evaluated in animal models.

A moving discontinuous Galerkin finite element method with interface condition enforcement for compressible flows

JOURNAL OF COMPUTATIONAL PHYSICS, 445.

By: H. Luo n, G. Absillis n & R. Nourgaliev*

author keywords: Discontinuous Galerkin methods; Moving grid methods; Conservation laws; Discontinuity tracking and fitting; Nonlinear least-squares problem
TL;DR: Numerical results obtained indicate that the MDG+ICE method is able to implicitly detect and track all types of discontinuities via interface conservation enforcement and satisfy the conservation law on both elements and interfaces via grid movement and grid management, demonstrating that an exponential rate of convergence for Sod and Lax-Harden shock tube problems can be achieved.
