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 ...

The Characteristics of Deep-Water Gravity Flow in the Sublacustrine Fan of the Upper Triassic Yanchang Formation in the Huachi Area, Ordos Basin

Applied Sciences
In the Ordos Basin, one of the most important oil- and gas-bearing basins, the Triassic Yanchang Formation has formed important source rocks, but is also a typical representative of continental deep-water sedimentation.

Dynamic, Unconstrained Optimization of Secreted Enzyme Production in Fed‐Batch Fermentation Using Reinforcement Learning

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Reinforcement learning (RL) has been used to control a wide range of dynamic processes, especially ones that are too complex to model well or have stochastic environmental perturbations. Fed‐batch fermentations are subject to changes in starting cell growth rates and process variations that can affect cell growth and secreted target production.

Mitigating suspended-sediment environmental pressure in subsea engineering through colliding turbidity currents

Results in Engineering
Turbidity currents have extensively been explored in quiescent environments. However, during several underwater activities (e.g., dredging and deep sea mining), generated turbidity currents could travel in opposite directions and interact with each other,

Using 250-M Surface Reflectance MODIS Aqua/Terra Product to Estimate Turbidity in a Macro-Tidal Harbour: Darwin Harbour, Australia

Remote Sensing, 2018
Turbidity is an indicator of the quality of water and usually exhibits variability associated with changing hydrodynamic conditions, which can be reflected in the sediment dynamics in coastal regions.

Protein thermal stability in the undergraduate biochemistry laboratory: Exploring protein thermal stability with yeast alcohol dehydrogenase

Biochemistry and Molecular Biology Education, Volume 53, Issue 2, Page 209-217, March/April 2025.
Abstract We created a novel laboratory experience where undergraduate students explore the techniques used to study protein misfolding, unfolding, and aggregation. Despite the importance of protein misfolding and aggregation diseases, protein unfolding is not typically explored in undergraduate biochemistry laboratory classes.
