The Formation Rate and Luminosity Function of Fast Radio Bursts
The Astrophysical Journal LettersFast radio bursts (FRBs) are millisecond-duration flashes with unknown origins. Their formation rate is crucial for unveiling physical origins. However, the luminosity and formation rate are degenerate when directly fitting the redshift distribution of ...

Effect of three representative surfactants on methane hydrate formation rate and induction time
Egyptian Journal of Petroleum, 2017 The effects of three types of surfactants on methane hydrate formation process were investigated. Three different classes of surfactants involving anionic (sodium dodecyl sulfonate), cationic (hexadecyl trimethyl ammonium bromide) and non-ionic (poly oxy

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.

CSF formation rate—a potential glymphatic flow parameter in hydrocephalus?
Fluids and Barriers of the CNSBackground Studies indicate that brain clearance via the glymphatic system is impaired in idiopathic normal pressure hydrocephalus (INPH). This has been suggested to result from reduced cerebrospinal fluid (CSF) turnover, which could be caused by a ...

Numerical studies of gas hydrate evolution time in Shenhu area in the northern South China Sea
China Geology, 2019 : Although the Shenhu sea area has been a topic and focus of intense research for the exploration and study of marine gas hydrate in China, the mechanism of gas hydrate accumulation in this region remains controversial.

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

FEBS 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.

Numerical investigation of soot formation in diesel jet flame with KIVA-3V
Revue des Énergies Renouvelables, 2009 Diesel engines emit a Large amount of pollutants essentially soot particles. This paper describes a 3D modeling on platform of a 3-D code for engine thermodynamic simulation Kiva-3V. A Hiroyasu model for soot formation was used originally, it’s a twostep

Searching for Rate Determining Step of CNT Formation: The Role of Cementite
Chemical Engineering Transactions, 2013 We produce multiwall carbon nanotubes in a large-scale fluidized bed reactor, in which catalytic chemical vapour deposition occurs. The catalyst employed is iron supported over alumina, whereas the carbon source is ethylene, which is fed together with ...

Reconstructing enzyme evolution by protein engineering
FEBS 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 ...
