On bypass transition in separation bubbles: a review
Transition from laminar flow to turbulent flow is of great practical interest as it occurs in many engineering flows and often plays a critical role in aerodynamics and heat transfer performance of those flow devices.

Dynamical arrest in active nematic turbulence
Active fluids display spontaneous turbulentlike flows known as active turbulence. Recent work revealed that these flows have universal features, independent of the material properties and of the presence of topological defects.

Effect of cell retention techniques in Komagataella phaffii lab‐scale continuous processes
Abstract Perfusion technologies play a growing role in the implementation of continuous processes for biotherapeutics production in mammalian‐based manufacturing. However, their application to alternative production hosts is limited. Cell retention systems are of key importance for the efficiency of perfusion bioreactors.

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,

STRUCTURE OF TURBULENT VELOCITY AND BUOYANCY FLUCTUATIONS IN STRATIFIED TURBULENT SHEAR FLOW
The effects of buoyancy on turbulence structure of a buoyant surface jet are investigated. Velocities and buoyancy fluctuations are simultaneously measured, and their statistic quantities are examined. Distributions of turbulence quantities are strongly affected by buoyancy. Their variations against the shear layer Richardson number can be explained in
