Synergistic effects of organic material returning on soil carbon sequestration and wheat productivity on the Qinghai Plateau

Frontiers in Agronomy
ObjectiveThe Qinghai Plateau is a core component of global plateau terrestrial ecosystems. Clarifying the impacts of organic material incorporation on soil organic carbon sequestration can reveal carbon cycling patterns in plateau farmlands worldwide. It

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

FEBS 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 ...

The spectrum of near-BPS Kerr-Newman black holes and the ABJM mass gap

Journal of High Energy Physics
Supersymmetric rotating 1/16-BPS black holes in AdS 4 × S 7 are expected to capture the average degeneracy of BPS states in the dual ABJM superconformal theory for given fixed charges.

Experimental study on fractures quantitative characterization of shale during uniaxial compression

Frontiers in Earth Science
IntroductionFractures are crucial to the development of shale oil and gas because they operate as a seepage pathway. The key to ensuring effective development is the fractures strong connection.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

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.

The role of visibility as a predictor of children’s location choices in outdoor school grounds across age and gender

Frontiers in Psychology
Children’s activities in school grounds are shaped by spatial design, affordances and social dynamics rather than preference alone. This study examines how children of different ages and gender use playground spaces, and how the design and visual depth ...

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Coastal public realms and housing livability in Saudi cities: developing a comprehensive waterfront development index (CWDI) for Jeddah

Frontiers in Built Environment
IntroductionUrban waterfronts in Gulf cities are strategic public assets crucial for environmental risk management and enhancing the livability of surrounding residential and national housing areas, yet most existing urban evaluation indices are city ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
