ON A MODEL OF CONCURRENT SYSTEMS

open access: yesDemonstratio Mathematica, 1997
Summary: In some systems the possibility of concurrent execution of activities can be described by very irregular conditions which can not be modeled by Petri nets. In the paper a kind of models of such systems and a new definition of Petri nets are described.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS 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

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Modelling and simulation of the dynamic behaviour of a ball screw system using transmission line modelling technique [PDF]

open access: yes
This paper presents a new approach for the modelling of a screw shaft including the axial and torsional dynamics in the same model. The model includes the distributed parameter dynamics of the ball screw system and the effect of mass distribution.

Decadal sink-source shifts of forest aboveground carbon since 1988

open access: yesNature Communications
Forest ecosystems are vital to the global carbon cycle, yet their long-term aboveground carbon (AGC) dynamics remain uncertain. Here, we integrate multi-source satellite observations with probabilistic deep learning models to reconstruct a harmonized ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Burned Area Over Africa Reduced by Shortened Dry Season

open access: yesGeophysical Research Letters
While most of Africa's burned area occurs during the dry season, the relationship between dry season characteristics and fire activity remains poorly understood.
