On the validity of the Boltzmann-BGK model through relaxation evaluation

open access: yes, 2014
The Boltzmann-Bhatnagar-Gross-Krook (BGK) model is investigated for its validity regarding the collision term approximation through relaxation evaluation. The evaluation is based on theoretical analysis and numerical comparison between the BGK and direct

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

An integrated approach to evaluation: A participatory model for reflection, evaluation, analysis and documentation (the 'READ' model) in community arts

open access: yes, 2016
The research focuses on the development and critical review of the READ model, a dynamic and rigorous model for evaluation of community arts. The model's innovation lies in the integration of four key appraisal and learning strategies- Reflection ...

Integrating the Funder-Fundee Relationship into a Model of Evaluation Utilization

open access: yes, 2011
Background: Evaluation is a tool that can promote accountability and enhance organizational improvement. For these reasons funding entities from government to foundations are increasingly relying on program evaluation as a key instrument to determine ...

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

A Method to Evaluate Response Models

open access: yes, 2014
We are working towards computational models of mind of virtual characters that act as suspects in interview (interrogation) training of police officers. We implemented a model that calculates the responses of the virtual suspect based on theory and observation. We evaluated it by means of our test, the “Guess who you are talking to?‿ test. We show that

Communicating About Evaluation: A Conceptual Model and Case Example

open access: yes, 2017
Background: Despite consensus within the evaluation community about what is distinctive about evaluation, confusion among stakeholders and other professions abounds.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
