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.

Bidirectional Jump Point Search Path-Planning Algorithm Based on Electricity-Guided Navigation Behavior of Electric Eels and Map Preprocessing

Biomimetics, 2023
The electric eel has an organ made up of hundreds of electrocytes, which is called the electric organ. This organ is used to sense and detect weak electric field signals.

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 ...

Intra- versus inter-sexual selection in the dimorphic electric organ discharges of the snoutfish Marcusenius altisambesi (Mormyriformes, Teleostei) [PDF]

, 2010
Marcusenius pongolensis (South Africa) and M. altisambesi (Upper Zambezi/Okavango) differ in the sex difference of their electric organ discharges (EODs). It is permanent and graded in the former and seasonally dimorphic in the latter.

Development of the electric organ in embryos and larvae of the knifefish, Brachyhypopomus gauderio.

Dev Biol, 2020
South American Gymnotiform knifefish possess electric organs that generate electric fields for electro-location and electro-communication. Electric organs in fish can be derived from either myogenic cells (myogenic electric organ/mEO) or neurogenic cells

Flight-associated discharge pattern in a weakly electric fish, Gnathonemus petersii (Mormyridae, Teleostei) [PDF]

, 1976
A Gnathonemus petersii which is put into the tank of a Mortnyrtts rume, or of an electrically silenced G. petersii, displays a discharge rate which is only one fourth (8 Hz) the rate exhibited by an attacking, territory-defending animal.
