The relatively common flare-associated radio bursts (type III) vary in occurrence rate rather substantially over the solar cycle, mimicking the variation in flare rate.
Starting from the observation that community initiatives vary in occurrence and variety across countries, we ask in what ways the institutional configuration of the energy sector facilitates or constrains community initiatives for renewable energy.
These HSEs vary in occurrence, number, position, and conformity with the canonical sequence.

The wetting-drying process in different soil subregions under SDI incurred pulse N2O emissions unexceptionally, but the pulse magnitudes and timing of the occurrence varied among subregions.
Fire occurrence varied between the four studied sites, but fires generally occurred more often during warm and dry periods of the Holocene, especially during the Holocene Thermal Maximum (7000 3500 cal. BP), when fire occurrence was twice as high as at present.
For estimation of heritability, we used information from families that had at least 2 members with the phenotypes of interest, which varied according to occurrence of the diseases.
