Electric Eels Wield a Functional Venom Analogue

Toxins, 2021
In this paper, I draw an analogy between the use of electricity by electric eels (Electrophorus electricus) to paralyze prey muscles and the use of venoms that paralyze prey by disrupting the neuromuscular junction.

Influence of Inlet Boundary Conditions on the Prediction of Flow Field and Hemolysis in Blood Pumps Using Large-Eddy Simulation

Bioengineering, 2023
Inlet boundary conditions (BC) are one of the uncertainties which may influence the prediction of flow field and hemolysis in blood pumps. This study investigated the influence of inlet BC, including the length of inlet pipe, type of inlet BC (mass flow ...

On the Optimization of a Centrifugal Maglev Blood Pump Through Design Variations

Frontiers in Physiology, 2021
Centrifugal blood pumps are usually designed with secondary flow paths to avoid flow dead zones and reduce the risk of thrombosis. Due to the secondary flow path, the intensity of secondary flows and turbulence in centrifugal blood pumps is generally ...

The Design and Evaluation of a Portable Extracorporeal Centrifugal Blood Pump

Frontiers in Physiology, 2021
In recent years, blood pumps have become the bridge to heart transplantation for patients with heart failure. Portability and wearability of blood pumps should be considered to ensure patient satisfaction in everyday life.

Electric imaging through evolution, a modeling study of commonalities and differences. [PDF]

PLoS Computational Biology, 2014
Modeling the electric field and images in electric fish contributes to a better understanding of the pre-receptor conditioning of electric images. Although the boundary element method has been very successful for calculating images and fields, complex ...
