A Review of the Applications and Challenges of Pulsed Electric Fields in Fish Ecological Protection

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT The use of pulsed electric fields (PEF) to regulate fish swimming patterns, especially during migratory channel restoration in dammed rivers, faces significant operational challenges. These challenges can generally be attributed to the multifaceted nature of fish behaviour and limitations in research on physical interception methods.

Marangoni Flow Before Carlo Marangoni

Annalen der Physik, Volume 538, Issue 6, June 2026.
ABSTRACT In fluid dynamics, particularly in research on soft matter, it is well known that surface tension gradients drive fluid flow, a phenomenon known as Marangoni flow. The effect is named after Carlo Marangoni, who described it in 1865 as part of his doctoral thesis on droplets and liquid films. While Marangoni's contribution is rightly recognized,

Three‐Year Characterization of Boundary Layer Dynamics From GNSS Zenith Wet Delay Spectral Analysis

Atmospheric Science Letters, Volume 27, Issue 6, June 2026.
Three years of GNSS zenith wet delay observations at Payerne reveal that spectral parameters—cutoff frequency α and variance σ2—capture robust seasonal cycles in boundary layer turbulence (R2 = 0.54 for α). Their inverse coupling tightens to r = −0.82 under summer convection, encoding regime‐dependent physics.

Raman Spectroscopy–Based Glucose Feed Control Automates Malic Acid Fermentation

Biotechnology and Bioengineering, Volume 123, Issue 6, Page 1721-1732, June 2026.
Raman spectroscopy enables automated, closed‐loop glucose feeding for malic acid production with Ustilago trichophora. Online PLS regression of glucose and malic acid provides input for PID control to maintain 20 g/L glucose. The feed is dynamically adjusted and stopped in response to metabolic demand and product inhibition, demonstrating practical ...
