Estimates of effective population size.

open access: yes, 2012
A) Contemporary effective population size (Ne) for each sample site based on maximum likelihood estimation using COLONY software. Bar represents maximum likelihood Ne estimate, error bars represent upper and lower 95% percentiles.

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

Cloud optical thickness, cloud particle effective radius, and effective snow grain size retrieved from airborne spectral reflectivity measurements during VERDI 2012 over the Beaufort Sea

open access: yes, 2017
The data contain time series of cloud optical thickness, cloud particle effective radius, and effective snow grain size retrieved from airborne spectral reflectivity measurements during the Vertical Distribution of Ice in Arctic Clouds (VERDI) campaign ...

Effective Size and Number of Components [PDF]

open access: yes, 1981
Two families of indices are defined which may be used to characterize the effective number of components in systems with unequal component sizes. A general formula is staled relating size, effective size, and effective number of components. Special cases

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

Sector and size effects on effective corporate taxation [PDF]

open access: yes
The current debate in corporate taxation is focussing on leveling the tax playing field within the European Union in order to allow companies incorporated in different countries to face the same competitive conditions.

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 ...

Effective population size estimation.

open access: yes, 2015
The census population size (N) versus the estimated effective population size (N̂e) for 1,000 simulated E&R experiments. For each simulation, population size was chosen uniformly at random from the interval [10, 104].

Prediction and estimation of effective population size [PDF]

open access: yes, 2016
Effective population size (Ne) is a key parameter in population genetics. It has important applications in evolutionary biology, conservation genetics, and plant and animal breeding, because it measures the rates of genetic drift and inbreeding and ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
