Development of a predictive model for cell growth in shaken bioreactors as a function of the effects of temperature, oxygen transfer rate and seeding cell concentration

The objective of this study was to develop a model for the growth of Chinese Hamster Ovary (CHO) cells in shaken bioreactors. For this purpose a modified three parameters Gompertz equation was used to fit lag, exponential and stationary growth phases. Usin ...

Replaying the Evolutionary Tape: Biomimetic Reverse Engineering of Gene Networks

Dario Floreano, Claudio Mattiussi, Daniel Marbach

In this paper, we suggest a new approach for reverse engineering gene regulatory networks, which consists of using a reconstruction process that is similar to the evolutionary process that created these networks. The aim is to integrate prior knowledge int ...

Comment on 'The effect of evaporation on the wicking of liquids into a metallic weave' by N. Fries, K. Odic, M. Conrath and M. Dreyer

David Andrew Barry, Laurin Wissmeier

A recent paper reported capillary rise and evaporation experiments in metallic wicks, as well as a mathematical model. The authors found a consistent discrepancy between the model predictions and data: The model over-predicted the capillary height rise by ...

Stiffness degradation and life prediction of adhesively- bonded joints for fiber-reinforced polymer composites

Thomas Keller, Anastasios Vassilopoulos, Ye Zhang

Adhesively-bonded joints, including double- and stepped- lap joints (DLJs and SLJs), were experimentally investigated under cyclic tensile loading. The joints were composed of pultruded GFRP laminates and epoxy adhesive. A critical stiffness was found for ...

An integrated adaptive model for overheating risk prediction

Darren Robinson, Frédéric Haldi

Based on the results from a field survey campaign, this article describes three new developments which have been integrated to provide a comprehensive basis for the evaluation of overheating risk in offices. Firstly, a set of logistic regression equations ...

On the behaviour and adaptation of office occupants

Darren Robinson, Frédéric Haldi

During the warm summer of 2006 a comprehensive longitudinal field survey of the adaptive actions of occupants, their thermal satisfaction and the coincident environmental conditions was conducted in eight Swiss office buildings. We have applied logistic re ...

Accurate parametric inference for small samples

Anthony Christopher Davison

We outline how modern likelihood theory, which provides essentially exact inferences in a variety of parametric statistical problems, may routinely be applied in practice. Although the likelihood procedures are based on analytical asymptotic approximations ...

Sparse Probabilistic Classifiers

The scores returned by support vector machines are often used as a confidence measures in the classification of new examples. However, there is no theoretical argument sustaining this practice. Thus, when classification uncertainty has to be assessed, it i ...

River networks and ecological corridors: Reactive transport on fractals, migration fronts, hydrochory

Andrea Rinaldo, Enrico Bertuzzo, Amos Maritan, Marino Gatto

Moving from a recent quantitative model of the US colonization in the 19th century that relies on analytical and numerical results of reactive-diffusive transport on fractal river networks, this paper considers its generalization to include an embedded flo ...
