Population and Endogenous Growth [PDF]

Using a general three sector growth model, this paper derives general conditions for positive growth in the economy along a balanced growth path under the alternative assumptions of a static population and a growing population.

Land reforms and population growth [PDF]

Portuguese Economic Journal, 2016
One of the greatest puzzles in demographic history is why in the rich and urbanized England, fertility declined much later than in the poor and rural France. We consider the effects of a land reform on demographic growth by a family-optimization model where relative per capita wealth generates social status and welfare.

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

FEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

Population growth in new Hispanic destinations [PDF]

, 2008
Natural increase—more births than deaths—is now the major engine of Hispanic population growth in many large metro areas and their suburbs, as well as numerous smaller metropolitan areas and rural communities.

Population Growth and Carbon Emissions [PDF]

SSRN Electronic Journal, 2016
We provide evidence that lower fertility can simultaneously increase income per capita and lower carbon emissions, eliminating a trade-off central to most policies aimed at slowing global climate change. We estimate the effect of lower fertility on carbon emissions accounting for the fact that changes in fertility patterns affect carbon emissions ...

Making tau amyloid models in vitro: a crucial and underestimated challenge

FEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Stochastic population growth in spatially heterogeneous environments

, 2012
Classical ecological theory predicts that environmental stochasticity increases extinction risk by reducing the average per-capita growth rate of populations.

On the momentum of population growth [PDF]

Demography, 1971
Abstract If age-specific birth rates drop immediately to the level of bare replacement the ultimate stationary number of a population will be given by (9): multiplied by the present number, where b is the birth rate, r the rate of increase, the expectation of life, and R0 the Net Reproduction Rate, all before the drop in fertility, and μ

The power of microRNA regulation—insights into immunity and metabolism

FEBS Letters, EarlyView.
MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...

The Outlook for Population Growth [PDF]

Science, 2011
Projections of population size, growth rates, and age distribution, although extending to distant horizons, shape policies today for the economy, environment, and government programs such as public pensions and health care. The projections can lead to costly policy adjustments, which in turn can cause political and economic turmoil.
