Convergence of One-Leg Hybrid Methods for Implicit Mixed Differential Algebraic Systems

open access: yesAbstract and Applied Analysis, 2015
This paper focuses on a hybrid multistep and its twin one-leg methods and implementing them on implicit mixed differential algebraic equations. The orders of convergence for the above methods are discussed and numerical tests are solved.

A Guide to Bayesian Optimization in Bioprocess Engineering

open access: yesBiotechnology 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.

Improving the learning experience in an undergraduate course on microbial metabolism by using an illustrated story

open access: yesBiochemistry and Molecular Biology Education, Volume 53, Issue 2, Page 131-141, March/April 2025.
Abstract In the classroom, metabolism is often approached and received as a mundane exercise in memorization. Teaching metabolism also faces the challenge of negative perceptions that can impede learning. We sought to improve the learning experience in an undergraduate lecture course on microbial metabolism by implementing an illustrated story that ...

Numerical Solution of Integral-Algebraic Equations with Weakly Singular Kernels by k−step Methods

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2015
In this paper we describe numerical methods for solution integral-algebraic equations wiht weakly singular kernels. Methods are based on explicit Adam’s methods, product integration methods for the integral part and on extrapolation formulas for the main

Preventing and Recovering Food Waste in Manufacturing Firms: A Contingency Perspective on Circular Economy Practices

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Food waste is a sustainability concern in the food industry, which can be mitigated through a circular economy. Circularity can be limited by contextual constraints, such as the characteristics of the waste to be recovered. However, their study in the context of food waste is scarce.

An Algebraic Method on the Eigenvalues and Stability of Delayed Reaction-Diffusion Systems

open access: yesDiscrete Dynamics in Nature and Society, 2013
The eigenvalues and stability of the delayed reaction-diffusion systems are considered using the algebraic methods. Firstly, new algebraic criteria to determine the pure imaginary eigenvalues are derived by applying the matrix pencil and the linear ...

Uniform Gas Flow Distribution into Several Partial Flows under Consideration of Closable Outlets

open access: yesChemie Ingenieur Technik, EarlyView.
The uniform distribution of a gas flow into several partial flows poses a challenge in various technical fields. This study presents a static flow distributor design that ensures an equal distribution of an inlet gas flow regardless of the flow rate and the number of open outlets.

Learning hydrocracking reaction dynamics via neural ODEs: A data‐driven, gradient‐interpretable lumped modelling framework

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
This work demonstrates the application of neural ordinary differential equations (neural ODEs) for learning hydrocracking reaction kinetics directly from data, achieving robust predictions under noise and sparsity while preserving mechanistic interpretability through gradient‐based analysis of temperature‐ and concentration‐dependent reaction rates ...

A new view of relationship between atomic posets and complete (algebraic) lattices

open access: yesOpen Mathematics, 2017
In the context of the atomic poset, we propose several new methods of constructing the complete lattice and the algebraic lattice, and the mutual decision of relationship between atomic posets and complete lattices (algebraic lattices) is studied.
