Subexponential growth of early Christianity [PDF]
arXiv, 2021 This paper presents a simple mathematical model for the growth of the Christian population in the Roman Empire during the first to fourth centuries. The model has a subexponential growth rate of order $e^{o(t)}$, where $o$ denotes the "little-o" asymptotic bound, but still superpolynomial, and it fits available Christian population estimates with good ...

Effect of bacterial growth rate on bacteriophage population growth rate
MicrobiologyOpen, 2017 It is important to understand how physiological state of the host influence propagation of bacteriophages (phages), due to the potential higher phage production needs in the future.

Solution of Fuzzy Growth and Decay Model [PDF]
arXiv, 2017 Mathematical modelling for population growth leads to a differential equation. In population growth model, we assume that rate increase of population is proportional to current population. That is, dx / dt = kx, x is a current population, k is proportionality constant represents growth rate.

Reasons for unsafe abortion in Iran after pronatalist policy changes: a qualitative study
Reproductive HealthBackground In Iran, restrictive abortion laws have led to widespread unsafe abortions, posing significant health risks. The 2021 Family and Youth Protection Law further restricted access to reproductive health services in an effort to boost birth rates ...

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Impact of population growth and population ethics on climate change mitigation policy
Proceedings of the National Academy of Sciences of the United States of America, 2017 Significance We investigate how future population growth is relevant to climate change policy. The answer depends importantly on ethical questions about whether our ultimate goal should be to increase the number of people who are happy or rather to ...

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

The effects of stochasticity at the single-cell level and cell size control on the population growth [PDF]
arXiv, 2016 Establishing a quantitative connection between the population growth rate and the generation times of single cells is a prerequisite for understanding evolutionary dynamics of microbes. However, existing theories fail to account for the experimentally observed correlations between mother-daughter generation times that are unavoidable when cell size is ...

Winter temperatures limit population growth rate of a migratory songbird
Nature Communications, 2017 Understanding the factors that limit and regulate wildlife populations requires insight into demographic and environmental processes acting throughout the annual cycle.

miRNA‐29 regulates epidermal and mesenchymal functions in skin repair
FEBS Letters, EarlyView.miRNA‐29 inhibits cell‐to‐cell and cell‐to‐matrix adhesion by silencing mRNA targets. Adhesion is controlled by complex interactions between many types of molecules coded by mRNAs. This is crucial for keeping together the layers of the skin and for regenerating the skin after wounding.
