Illumination of atoms by resonant lasers can pump electrons into a coherent superposition of hyperfine levels which can no longer absorb the light. Such superposition is known as a dark state, because fluorescent light emission is then suppressed. Here w
3). Altogether, these results indicate that population activity in dlPFC strongly depends on ongoing behavioral state during wakefulness. Autocorrelation analysis reveals that population synchrony, PSI, is highly persistent as it changes slowly in time (over minutes, Supplementary Fig. 4a). This is ...
These policy changes saw and increase in immigrants particularly from Greece and Italy. Today, Australia maintains its status as an ‘’Immigrant nation’’, with almost 30 percent of the population born overseas and around 50 percent of the population having both that were born overseas. ...

“The main changes in China’s population over the past decade reflected the historical process of the nation’s population growth and socio-economic development. It also conforms to the trend of population growth and the objective law of interaction between the population and the economy and socie...
By 2050,half of the world's population will live in the tropics-the relatively warm belt that circles the globe-according to State of the Tropics,a report released today.Rapid population growth,along with economic growth,means that the region's influence will grow in coming decades,the authors...
Population genetics is the study of the genetic composition of populations, including distributions and changes in genotype and phenotype frequency in response to the processes of natural selection, genetic drift, mutation and gene flow. Featured ...
changes in various species8,9; in contrast, the loss of seed shattering has the same genetic basis in sorghum, rice, maize and foxtail millet10,11,12. The impact of domestication on genomes has been mainly studied in annual crops and seldom investigated in fruit tree crops13. The long juve...

1b–d). Models differed in the directionality of gene flow, population size changes following divergence, and in patterns of secondary contact following divergence. Genetic clusters in Structure were largely partitioned East and West in the TWA, and 25 individuals from each putative population (50...
