Description:: Islet transplantation is a therapy in which insulin-producing beta (β) islet cells are infusedinto the liver via the portal vein to restore glycemic control. This therapy is beneficial for patients suffering from chronic pancreatitis or type I diabetes. However, islet transplantation is not widely implemented due to the instant blood-mediated...

Description:: Found in 1-2% of the population, bicuspid aortic valve (BAV) is the most common congenital cardiovascular disease and is associated with increased risk of aortic valve dysfunction and aortic disease. Current treatment is focused on surgical intervention either after the development of symptomatic aortic stenosis/regurgitation or aortic diameter thresholds. However,...

Description:: Decisions in naturalistic environments usually feature delayed and uncertain outcomes that can only be reached after a sequence of actions are performed. For example, canonical stalking and pursuit strategies used by terrestrial predators often involve stages of concealment, pauses where the predator remains motionless, and high speed chase sequences. The...

Description:: Maneuvering your limbs requires both accurate commands for how to move, and accurate feedback of their true movements. Conventional prosthetic arms currently lack this sense of proprioceptive feedback, which can make daily tasks difficult without close visual monitoring. Although studies have successfully provided artificial proprioceptive feedback to improve control, this...

Description:: End-stage renal disease, or kidney failure, can result from acute kidney injury or sustained kidney damage in the form of chronic kidney disease. As the prevalence of end-stage renal disease continues to rise, the gold-standard treatment—kidney transplantation—is increasingly restricted by the shortage of transplantable donor kidneys. Bioengineered kidney tissues may...

Description:: One method of cancer treatment is to thermally ablate (destroy) tumor masses using heat caused by electric current, or Joule heating. This particular modality is called radiofrequency ablation (RFA), due to the use of electric currents in the 100 kHz to 800 kHz frequency range. Computationally, RFA is simulated as...
