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 ...

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 ...

Geometrical nonlinear analysis of thin-walled composite beams using finite element method based on first order shear deformation theory

open access: yes, 2011
Based on a seven-degree-of-freedom shear deformable beam model, a geometrical nonlinear analysis of thin-walled composite beams with arbitrary lay-ups under various types of loads is presented.

STRUCTURAL BEHAVIOR OF GFRP-CONCRETE COMPOSITE COLUMNS UNDER AXIAL LOAD

open access: yesInternational Journal for Computational Civil and Structural Engineering
Glass Fiber Reinforced Polymer (GFRP) is emerging as an effective alternative to traditional steel in construction due to its superior ability to withstand high loads, light weight, corrosion resistance and low maintenance costs.

Radial Columns in Cortical Architecture: It Is the Composition That Counts [PDF]

open access: yesCerebral Cortex, 2010
The function of any brain structure depends on its neuronal composition and on the pattern of its extrinsic and intrinsic excitatory and inhibitory synaptic connectivity. In this issue of Cerebral Cortex, 3 related papers provide the most comprehensive analysis to date of the cellular and synaptic relationships of a standard cortical column in the ...

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 ...

Finite element modelling of shear connection for steel-concrete composite girders [PDF]

open access: yes, 2002
The main objective of this thesis is to develop effective 3-dimensional finite element models to trace the behaviour of headed stud shear connectors in composite girders with solid slabs and precast hollow core slabs.

Mechanical Performance of Prefabricated Monolithic Composite Columns with Reinforced ECC Precast Shell

open access: yesBuildings
To enhance the mechanical properties of a precast monolithic column, the ECC material was made into a prefabricated shell with reinforced bars. Post-cast concrete was poured into the precast parts to form the reinforced ECC precast monolithic composite ...

Compressive strength capacity of light gauge steel composite columns

open access: yesCase Studies in Construction Materials, 2016
The axial compressive strength capacity of concrete-filled light gauge steel composite columns was assessed through an experimental program involving twelve long and fourteen stub columns with width-to-thickness ratio of 125 for the encasing steel ...
