DOI: 10.1038/s41598-020-77483-3
Abstract: The current ecological understanding still does not fully explain how biodiversity is maintained. One strategy to address this issue is to contrast theoretical prediction with real competitive communities where diverse species share limited resources. I… read more here.

DOI: 10.1051/0004-6361/201730599
Abstract: In recent years it has been claimed that the length of stellar activity cycles is determined by the stellar rotation rate. It is observed that the cycle period increases with rotation period along the so-called… read more here.

Abstract: Magnetic cycles have been detected in tens of solar-like stars. The relationship between the cycle properties and global stellar parameters is not fully understood yet. We searched for activity cycles in 90 solar-like stars with… read more here.

DOI: 10.1093/mnras/stad1460
Abstract: This study presents new prediction models of the 11-year solar activity cycles (SC) 25 and 26 based on multiple activity indicator parameters. The developed models are based on the use of Nonlinear Autoregressive Exogenous (NARX)… read more here.

Daytime rest: Association with 24‐h rest–activity cycles, circadian timing and cognition in older adults

DOI: 10.1111/jpi.12820
Abstract: Growing epidemiological evidence points toward an association between fragmented 24‐h rest–activity cycles and cognition in the aged. Alterations in the circadian timing system might at least partially account for these observations. Here, we tested whether… read more here.
