200 years ago there were less than one billion humans living on earth. Today, according to UN calculations there are over 7 billion and projected in 2100 it will be around 11 billion with the growth rate of 2.1. At 1 BC the the population expected to be 188 Million, and at 10000 BC ...
Hefei’s milestone of a trillion-yuan GDP and a 10-million population is not just a marker of urban development but a starting point for even greater ambitions. As the city continues to grow, enhancing public services and maintaining quality of life will become critical challenges that require ...
Conversely, cities undergoing densification face greater challenges in mitigating rising heat exposure. We further show that vegetation changes have a moderate association with changes in population-weighted heat exposure (R=0.56), whereas variations in surface albedo exhibit a negligible relationship (R=...

At the dawn of the 20th century, 1.5 billion humans lived on the planet [source: Historical Estimates of World Population]. Our population seems to increase with greater and greater speed as the centuries go on. The primary reason for this is simple -- each increase in population creates ...
regional gene flow from surrounding populations and different proportions of migration can accentuate the population diversity. For instance, although with a common ancestor, pairwise FSTbetween Han Chinese and Japanese and that between Han Chinese and Korean are both greater than that between north and...
that is, if the density of those infected by a unit density of infectives during their infectious lifetime is greater than one. The minimal velocity of the wave sweeping through the population in the region is c = 2√1 – b in the transformed coordinates, or as x/t = (rS0D)1/2 ...
Rapid urbanization in China is closely related to the contributions of the migrant population. Dongguan, a megacity located in the hinterland of the Guangdong-Hong Kong-Macao Greater Bay Area (GBA), has the highest proportion of the migrant population to
With HiFi reads, researchers are able to obtain phased genomes with high accuracy, more completeness, and greater resolution for all variant classes, robust coverage across challenging and repeat-rich regions, and genome-side methylation status for multiomics studies. And as the CPC project found, ...
