Suppression of Fluid Forces Acting on Two Square Prisms in Tandem Arrangement by Passive Control. [PDF]
The aim of the present study is to suppress the fluid forces acting on two square prisms in tandem arrangement, which is found in many cases in structures on land and in the ocean, by exerting passive control on an approaching flow using a small flat ...

Passivity-based output-feedback control of turbulent channel flow [PDF]
Automatica, 2016 This paper describes a robust linear time-invariant output-feedback control strategy to reduce turbulent fluctuations, and therefore skin-friction drag, in wall-bounded turbulent fluid flows, that nonetheless gives performance guarantees in the nonlinear turbulent regime.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome
FEBS Letters, EarlyView.This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified
