A green and optimized approach for lactic acid recovery from fermented molasses using n‐butanol for local industrial applications in Côte d’Ivoire

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Lactic acid is a valuable organic compound with wide applications in the pharmaceutical, food, and biodegradable plastics industries. As Côte d’Ivoire seeks to strengthen its industrial capacity and promote sustainable practices, the development of efficient and environmentally benign methods for the recovery and purification of lactic acid ...

Aggregating distributed energy resources for grid flexibility services: A distributed game theoretic approach

International Journal of Robust and Nonlinear Control, EarlyView., 2023
Abstract We propose a hierarchical energy management scheme for aggregating Distributed Energy Resources (DERs) for grid flexibility services. To prevent a direct participation of numerous prosumers in the wholesale electricity market, aggregators, as self‐interest agents in our scheme, incentivize prosumers to provide flexibility. We firstly model the

Longitudinal links of negative student–teacher relationships and positive class climate with traditional bullying and cyberbullying perpetration

British Educational Research Journal, EarlyView.
Abstract The current study aimed to investigate whether negative student–teacher relationships and within‐class perceptions of the class climate at the individual level, and positive class climates at the classroom level in fifth grade, were associated with traditional bullying and cyberbullying perpetration 1 year later, in sixth grade, in a sample of

A Guide to Bayesian Optimization in Bioprocess Engineering

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Bayesian optimization has become widely popular across various experimental sciences due to its favorable attributes: it can handle noisy data, perform well with relatively small data sets, and provide adaptive suggestions for sequential experimentation.

Weighted spectral geometric means and matrix equations of positive definite matrices involving semi-tensor products

AIMS Mathematics
We characterized weighted spectral geometric means (SGM) of positive definite matrices in terms of certain matrix equations involving metric geometric means (MGM) $ \sharp $ and semi-tensor products $ \ltimes $. Indeed, for each real number $ t $ and two
