FEBS 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 ...

Automated detection, labelling and radiological grading of clinical spinal MRIs
Scientific ReportsSpinal magnetic resonance (MR) scans are a vital tool for diagnosing the cause of back pain for many diseases and conditions. However, interpreting clinically useful information from these scans can be challenging, time-consuming and hard to reproduce ...

Optimization of voids in concrete ceilings: A geometrical approach [PDF]
FME Transactions, 2019 The task to reduce the material consumption in the building industry is urgent. Conserving concrete saves nature and money. To reduce the consumption of concrete in buildings we design hollow bodies in ceiling structures.

A low-energy limit of Yang-Mills theory on de Sitter space
Journal of High Energy Physics, 2021 We consider Yang-Mills theory with a compact structure group G on four-dimensional de Sitter space dS4. Using conformal invariance, we transform the theory from dS4 to the finite cylinder I $$ \mathcal{I} $$ × S 3, where I $$ \mathcal{I} $$ = (−π/2, π/2)

Journal of Applied Non-Classical Logics, 2003 There are two natural ways of thinking about negation: (i) as a form of complementation and (ii) as an operation of reversal, or inversion (to deny that p is to say that things are “the other way around”). A variety of techniques exist to model conception (i), from Euler and Venn diagrams to Boolean algebras.

FEBS 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

The Safety of Learners and Teachers in School: A Criminological Analysis
International Journal of Social Sciences & Educational StudiesRecent study revealed that safety of learners and teachers continues to be a matter of major concern in the South African schools. Learners and teachers are no longer safe due to an increased level of violence in the schools.

CENS: A Coverage-Efficient Pixel Sampling Strategy for Enhancing NeRF-Generated Point Cloud Fidelity [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesMany geospatial workflows critically depend on high-fidelity 3D point clouds for applications such as change detection, orthophoto generation, and modeling.

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Journal of High Energy Physics, 2015 We investigate exceptional generalised diffeomorphisms based on E8 (8) in a geometric setting. The transformations include gauge transformations for the dual gravity field. The surprising key result, which allows for a development of a tensor formalism, is that it is possible to define field-dependent transformations containing connection, which are ...
