A convoy of magnetic millirobots transports endoscopic instruments for minimally-invasive surgery [PDF]

open access: yesarXiv
Small-scale robots offer significant potential in minimally-invasive medical procedures. Due to the nature of soft biological tissues, however, robots are exposed to complex environments with various challenges in locomotion, which is essential to overcome for useful medical tasks.

Inertial migration in dilute and semi-dilute suspensions of rigid particles in laminar square duct flow [PDF]

open access: yesarXiv, 2017
We study the inertial migration of finite-size neutrally buoyant spherical particles in dilute and semi-dilute suspensions in laminar square duct flow. We perform several direct numerical simulations using an immersed boundary method to investigate the effects of the bulk Reynolds number $Re_b$, particle Reynolds number $Re_p$ and duct to particle size

Uniqueness of Transonic Shock Solutions in a Duct for Steady Potential Flow [PDF]

open access: yesarXiv, 2008
We study the uniqueness of solutions with a transonic shock in a duct in a class of transonic shock solutions, which are not necessarily small perturbations of the background solution, for steady potential flow. We prove that, for given uniform supersonic upstream flow in a straight duct, there exists a unique uniform pressure at the exit of the duct ...

Endoscopic biliary stenting for post-cholecystectomy bile leaks [PDF]

open access: yes, 2016
This paper deals analyzes the treatment experience of 15 patients with bile leakage after laparoscopic cholecystectomy. All patients have undergone endoscopic transpapillary interventions in the bile ducts, including a retrograde cholangiography ...
