Mathematical Modeling of Drug Transport in Brain Tumors

Y. Guo [1], M. O. Bernabeu [2], C. D. Arvanitis [1],
[1] Georgia Institute of Technology, Atlanta, GA, USA
[2] University of Edinburgh, Edinburgh, United Kingdom

Blood-brain and blood-tumor barriers (BBB and BTB) constitute a major obstacle to the transport of therapeutics in brain tumors. Focused ultrasound (FUS), when combined with circulating microbubbles, provides a noninvasive method to locally and transiently disrupt the BBB/BTB. ... Read More

Improving Thermal Effect on Biological Tissue using Multiphysics Simulation and Shape Optimization

A. Ward [1],
[1] System Insight Engineering, Centennial, CO, USA

As minimally invasive and robotic surgical devices get smaller, designing precise energy delivery to create the desired tissue effect becomes a key component in product development. With many interdependent physical phenomena occurring simultaneously, it becomes necessary to use tools ... Read More

Generation of SFQ-Pulses in SNS-Junctions: Learning Physics using the COMSOL Multiphysics® software

A. M. Gulian [1], G. Melkonyan [2],
[1] Advanced Physics Laboratory, Chapman University, Burtonsville, MD, USA
[2] GMLabs, Quebec, QC, Canada

Single Flux Quantum, or SFQ, dynamics is at the heart of superconducting electronics. So are the Josephson junctions, or in a wider context, weakly-coupled superconducting junctions, in particular, superconductor-normal metal -superconductor, or SNS, junctions. Despite the COMSOL ... Read More

Generation of Divergence-Free Bessel-Gauss Beam from an Axicon Doublet for km-Long Collimated Laser

C. Daengngam [1], S. Boonsit [1], P. Kalasuwan [1], P. van Dommelen [1], P. Srisamran [1],
[1] Department of Physics, Faculty of Science, Prince of Songkla University, Songkhla, Thailand

A well-collimated intensity profile at long distance has long been a desired laser property crucial for many potential applications. Extending a non-diverging range for ordinary laser beyond kilometers scale would permit superior performance for optical technologies, including LIDAR, or ... Read More
