Dynamic pH profiles drive higher cell‐specific and volumetric productivity

Biotechnology Progress, EarlyView.
Implementation of dyamic pH profiles for increased CHO cell culture productivity. Abstract Mammalian cell cultures in bioreactors rely heavily on critical process parameter control to ensure optimal growth, productivity, and reproducibility to produce recombinant therapeutic proteins. Culture pH has been shown to be a critical parameter that influences

Mini‐Hairpin DNA: Extraordinarily Stable Structure and Its Applications

Chemistry – A European Journal, EarlyView.
Mini‐hairpin DNA fragments containing GCGAAGC and GCGAAAGC form exceptionally stable hairpin‐like structures, with only two G−C pairs and one sheared G−A pair, remaining undenatured in 7 M urea and resisting nuclease digestion. These mini‐hairpin sequences frequently appear in replication and transcription origins, influence DNA sequencing fidelity ...

On the Method of Harmonic Balance for Lumped‐Element Transformer Models

International Journal of Circuit Theory and Applications, EarlyView.
The steady‐state solution of a lumped‐element transformer model with a dry friction‐like hysteresis model depicting the magnetic core is of interest. The harmonic balance method efficiently solves this stiff system. We derive the harmonic balance algorithm, enhance it with performance and convergence improvements, and demonstrate its efficiency by ...

Synergistic Enhancement of Modified‐PVDF Humidity Sensitivity via Chemical Adsorption‐Ionic Conductivity and its Application in Intelligent Powered Air‐Purifying Respirator

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The study developed a PVDF/SiO2 humidity sensor with superhydrophobic properties and integrated the humidity sensor into the intelligent powered air‐purifying respirator (IPAPR) for breath monitoring. Coupled with the Gated Recurrent Unit (GRU) machine learning prediction algorithm, it enables feedforward control of the fan to achieve respiratory ...

The Gas‐Liquid Separation Characteristics Inside a Drainage Self‐Priming Pump Under Different Discharge Valve Openings

Energy Science &Engineering, EarlyView.
To investigate the influence of discharge valve opening on the self‐priming characteristics of a self‐priming pump, numerical calculations are conducted for four different discharge valve openings based on a circulation piping system. The hydraulic performance and the internal flow characteristics during self‐priming process are obtained.
