Raman Spectroscopy–Based Glucose Feed Control Automates Malic Acid Fermentation

Biotechnology and Bioengineering, EarlyView.
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 ...

Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

Deep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...
