Mangarara Formation: exhumed remnants of a middle Miocene, temperate carbonate, submarine channel-fan system on the eastern margin of Taranaki Basin, New Zealand [PDF]

open access: yes, 2009
The middle Miocene Mangarara Formation is a thin (1–60 m), laterally discontinuous unit of moderately to highly calcareous (40–90%) facies of sandy to pure limestone, bioclastic sandstone, and conglomerate that crops out in a few valleys in North ...

Raman Spectroscopy–Based Glucose Feed Control Automates Malic Acid Fermentation

open access: yesBiotechnology 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 ...

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

open access: yesBiotechnology 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.

Channel Confinement Drives Unidirectional Migration: Coupling of Flow Structure and Sedimentary Evolution in Combined Turbidity–Bottom Current Flows

open access: yesJournal of Marine Science and Engineering
Along-slope bottom currents and down-slope (gravity-driven) turbidity currents coexist in the ocean and interact during their flow processes. The interaction between turbidity currents and bottom currents plays a crucial role in determining the lateral ...

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

open access: yesBiochemistry 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.
