An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Aligning Initial Conditions With Long‐Term Model Dynamics to Enhance 4DVar‐Driven Medium‐Range Global Forecasts

open access: yesGeophysical Research Letters
Applying the four‐dimensional variational (4DVar) method in nonlinear systems faces conflicts between a lack of long‐term dynamical information using a short assimilation window and a trap of local minima using a long window.

Elastic-plastic analysis of bisteel i-section beams/Bimetalių dvitėjų sijų būvio analizė, įvertinant plastinių deformacijų įtaką

open access: yesJournal of Civil Engineering and Management, 2001
The elastic-plastic analysis of simple bisteel I-section beam subjected to uniform distributed load (Fig 1) is considered in this paper. The bisteel beam presents a composition of high-strength steel inclusions for the flanges in the region of maximum ...

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

Disturbance of sand samples obtained by piston samplers and ground freezing [PDF]

open access: yesE3S Web of Conferences
High quality sampling of sand and silty sands is extremely challenging. Undisturbed samples of sand can be obtained by means of very expensive and time-consuming techniques such as ground freezing.

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 ...

Colored Visualisation for Numerical Modelling. [PDF]

open access: yes, 2001
In this paper scalar and vector data are visualised by suited colour scales based on perceptive and uniform colour models. Using opportune colour scales, colour information is created from the two-dimensional scalar data computed at different time steps.

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 ...
