Comparative Analysis of Bioreactor Design and Scale‐Up for Cultivated Meat Using Monte Carlo‐Based Timescale Modeling

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Cultivated meat offers a sustainable alternative to conventional livestock production but faces significant scale‐up challenges, particularly in bioreactor design for mammalian cell suspension cultures. This study presents a comparative analysis of stirred tank reactors (STR), bubble columns (BC), and airlift reactors (ALR) to assess their ...

Resonance phenomena in the second differential order equations with nonlinear impulsive effects

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
In this paper, we discuss the resonance phenomena in linear and weakly nonlinear impulsive differential equations. Using a topological approach, we obtain the Landesman–Lazer type necessary and sufficient conditions for the existence of periodic ...

On the importance of including both sexes in animal studies – insights from home‐cage monitoring

open access: yesBiological Reviews, EarlyView.
ABSTRACT A review of behavioural studies using home‐cage monitoring (HCM) systems revealed that over 61% of studies used only male subjects, with only 24% including both sexes, despite evidence of substantial behavioural differences between male and female animals. This bias could influence the outcomes of biomedical research.

On Some New Impulsive Integral Inequalities

open access: yesJournal of Inequalities and Applications, 2008
We establish some new impulsive integral inequalities related to certain integral inequalities arising in the theory of differential equalities. The inequalities obtained here can be used as handy tools in the theory of some classes of impulsive ...

Integrating Products, Processes, and Sourcing for Eco‐Innovation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Eco‐innovation research has often examined regulatory or technological drivers but has paid limited attention to how long‐term organizational change shapes eco‐innovation in mature, resource‐intensive industries. This study addresses that gap by investigating how two leading Finnish pulp and paper firms integrated product, process, and ...

Piecewise weighted pseudo almost periodic solutions of impulsive integro-differential equations via fractional operators

open access: yesElectronic Journal of Differential Equations, 2015
In this article, we show sufficient conditions for the existence, uniqueness and attractivity of piecewise weighted pseudo almost periodic classical solution of nonlinear impulsive integro-differential equations.

Advanced glucose control strategies leveraging Raman spectroscopy for optimized mammalian cell culture manufacturing

open access: yesBiotechnology Progress, EarlyView.
Abstract Maintaining consistent quality in the manufacturing of biotherapeutic proteins in mammalian cell culture is challenging, with unplanned deviations causing inconsistencies and potential batch failure. Current methods for monitoring and controlling critical process parameters (CPPs) rely on slow, labor‐intensive offline analyses.
