Analysis of Co-evolving Gene Families Using Mutually Exclusive Orthologous Modules

Xiuwei Zhang

Coevolutionary networks can encapsulate information about the dynamics of presence and absence of gene families in organisms. Analysis of such networks should reveal fundamental principles underlying the evolution of cellular systems and the functionality ...

Refining transcriptional regulatory networks using network evolutionary models and gene histories

Bernard Moret, Xiuwei Zhang

Background: Computational inference of transcriptional regulatory networks remains a challenging problem, in part due to the lack of strong network models. In this paper we present evolutionary approaches to improve the inference of regulatory networks for ...

Efficient oxygen transfer by surface aeration in shaken cylindrical containers for mammalian cell cultivation at volumetric scales up to 1,000 liters

Alfio Quarteroni, Florian Maria Wurm, Nicola Parolini, Marco Discacciati, David Hacker, Xiuwei Zhang, Mathieu Benjamin Stettler, Marco Perrone, Dario De Sanctis

Cylindrical containers agitated by orbital shaking are being developed as simple and cost-effective bioreactor systems for the cultivation of mammalian cells. Here the oxygen transfer capacities of containers with nominal volumes from 50 mL to 2000 L were ...

Point Similarity Measures Based on MRF Modeling of Difference Images for Spline-Based 2D-3D Rigid Registration of x-Ray Fluoroscopy to CT Images

Michaël Unser, Philippe Thévenaz, Xiuwei Zhang

One of the main factors that affect the accuracy of intensity-based registration of two-dimensional (2D) X-ray fluoroscopy to three-dimensional (3D) CT data is the similarity measure, which is a criterion function that is used in the registration procedure ...
