Population Growth Population growth refers to change in the size of a population—which can be either positive or negative—over time, depending on the balance of births and deaths. If there are many deaths, the world's population will grow very slowly or can even decline. Population growth ...
embryoids, compounded by SOX17 overexpression may, in part, explain the low levels of anterior hypoblast formation in embryoids. Additionally, the low NODAL environment, combined with the lack of anterior hypoblast, may contribute to the differentiation of the epiblast-like population over time. ...
Archaeogenomic studies have largely elucidated human population history in West Eurasia during the Stone Age. However, despite being a broad geographical region of significant cultural and linguistic diversity, little is known about the population histor

Since the 1960s, world population has more than doubled, but the growth rate has been falling the entire time. We're witnessing the most fundamental shift to take place in modern human history. The shift towards pervasive and permanent low fertility, population aging and eventual depopulation. ...
The model is an extension of the overlapping-generation model introduced in the literature by Allais (1947), Diamond (1965) and Samuelson (1958) in discrete time t from 0 to infinity. For simplicity, I assume a single-sex population in a closed economy. The age structure is pooled in thr...
limited understanding of spill-over transmission mechanisms, which hampers the ability to predict this mode of transmission during the emergence of infectious diseases; 6. constraints in data sharing, particularly concerning morbidity, population mobility, social contacts, and healthcare information, which...
This study analyzes the human population growth rate and corresponding meat supply trend between 1991 and 2000 in Lagos State. Secondary data covering time and series were obtained from several Public Institutions. Human population data for Lagos State over the period showed an increase of 28.5% ...
a critical rationale for conducting further precision imaging studies of pregnancy in demographically enriched cohorts to determine the universality and idiosyncrasy of these adaptations and their role in maternal health. Are the changes observed in our participant reflective of the broader population?
(Fig.6). The sustainable population density was constant over time and exhibited little spatial variation. Consequently, the effect of changes in population density on the size of the total sustainable population was negligible. The small temporal and spatial variation in population density was a ...
