Functional Forms and Parametrization of Cge Models

open access: yesSSRN Electronic Journal, 2006
This study focused on the choice of functional forms and their parametrization (estimation of free parameters and calibration of other parameters) in the context of CGE models. Various types of elasticities are defined, followed by a presentation of the functional forms most commonly used in these models and various econometric methods for estimating ...

Disulfide bond reduction of antibodies during clarification: A bench‐scale assay and a mitigation tool

open access: yesBiotechnology Progress, EarlyView.
Abstract We investigated side‐by‐side clarification with a two‐stage depth filter system against a single‐stage charge chromatographic clarifier on a number of Chinese hamster ovary (CHO) cell cultures. We found that the one‐stage fibrous anion exchange (AEX) clarification met or exceeded the performance of the conventional two‐stage depth filtration ...

Multivariate phase‐dependent optimization of bioprocesses boosts performance and quality—Why timing (of exposure) matters

open access: yesBiotechnology Progress, EarlyView.
Abstract Applying a single parameter set to describe complex mammalian kinetics often is too simplistic, as it fails to capture sensitive cell‐to‐environment interactions that may be exploited to optimize production performance. To resolve this time dependency, intra‐experimental parameter shifts as part of design of dynamic experiments (DoDE) can be ...

Hypervision Proton Surgery: The Future Direction of Proton Therapy

open access: yesiNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...
