Experimental and numerical research of a supersonic planar thrust vectoring nozzle via mechanical tabs [PDF]

open access: yesFME Transactions, 2014
Wind tunnel cold flow tests were conducted, using the convergentdivergent two-dimensional nozzle, with a tab as the obstacle at the nozzle exit area. This geometry is applied in thrust vector control systems for missiles.

DELP Treatment on Vision and Retinal Microcirculation in Patients With Acute Ischemic Stroke: Report of Five Cases and Literature Review

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

A numerical study on aerodynamic resonance in transonic separated flow [PDF]

open access: yes, 2009
An ongoing numerical investigation of unsteady shock/boundary layer interaction on a 2-d supercritical airfoil in transonic flow is presented. Initially, the finitevolume URANS solver DLR-TAU is used to simulate self-sustained periodic shock oscillations

Cluster-based feedback control of turbulent post-stall separated flows

open access: yes, 2018
We propose a novel model-free self-learning cluster-based control strategy for general nonlinear feedback flow control technique, benchmarked for high-fidelity simulations of post-stall separated flows over an airfoil. The present approach partitions the

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Microfluidic free-flow electrophoresis for proteomics-on-a-chip [PDF]

open access: yes, 2008
A new free-flow electrophoresis microchip with integrated permeable membranes was developed, and different substances were separated by free-flow zone electrophoresis, free-flow isoelectric focusing and free-flow field step electrophoresis.
