Differential gut transmission of IncP plasmid clades involving hypervirulent Klebsiella pneumoniae reveals plasmid-specific ecological adaptation [PDF]

Nature Communications
Conjugative plasmids can drive the global spread of antimicrobial resistance (AMR) in Enterobacterales. Hypervirulent Klebsiella pneumoniae (hvKp) increasingly acquire AMR plasmids, raising concern about convergent hypervirulent drug-resistant clones ...

Dynamics of a capsule flowing in a tube under pulsatile flow

Journal of the Mechanical Behavior of Biomedical Materials, 2019
We analyze numerically the behavior of a deformable micro-capsule confined in a pipe under a pulsatile flow. The capsule moves and is deformed by the action of a pulsatile flow inside the tube with a non-null mean velocity. This configuration can be found in the nature and in many bioengineering systems where artificial capsules are driven by micro ...

Dynamics of a Supramolecular Capsule Assembly with Pyrene [PDF]

Journal of the American Chemical Society, 2012
Water-soluble octaacid cavitands (OAs) form dimeric capsules suitable for guest incorporation. Our studies reveal that the mechanism of pyrene (Py) binding involves the rapid (

A Magnetically Capsule Robot for Biomedical Application

Applied Bionics and Biomechanics, 2022
Magnetic-driven capsule robot has been widely studied due to its advantages of safety and reliability. However, when doctors carry out clinical examination, the capsule robot cannot achieve the ideal control effect due to the influence of the external ...

Affordance detection with Dynamic-Tree Capsule Networks

2022 IEEE-RAS 21st International Conference on Humanoid Robots (Humanoids), 2022
Affordance detection from visual input is a fundamental step in autonomous robotic manipulation. Existing solutions to the problem of affordance detection rely on convolutional neural networks. However, these networks do not consider the spatial arrangement of the input data and miss parts-to-whole relationships.

Tracking and Dynamic Tuning of a Wireless Powered Endoscopic Capsule

Sensors, 2022
This work presents an inductive wireless power transfer system for powering an endoscopy capsule supplying energy to power electronic devices allocated inside a capsule of ≈26.1 mm × 9 mm. A receiver with three coils in quadrature with dimensions of ≈9 mm × 9 mm × 10 mm is located inside the capsule, moving freely inside a transmitter coil with 380 mm ...

Transient dynamics of an elastic capsule in a microfluidic constriction [PDF]

Soft Matter, 2013
In this paper we investigate computationally the transient dynamics of an elastic capsule flowing in a square microchannel with a rectangular constriction, and compare it with that of a droplet. The confinement and expansion dynamics of the fluid flow results in a rich deformation behavior for the capsule, from an elongated shape at the constriction ...
