Pervasive shifts in forest dynamics in a changing world
Science, 2020 Shifting forest dynamics Forest dynamics are the processes of recruitment, growth, death, and turnover of the constituent tree species of the forest community. These processes are driven by disturbances both natural and anthropogenic.

Frequency shifts in natural vibrations in pantographic metamaterials under biaxial tests [PDF]
, 2017 In this paper a 2D continuum model, thought as the homogenized limit of a microstructured pantographic sheet, is studied. The microstructure is characterized by two families of parallel fibers, whose deformation measures account for bending, elongation ...

Radiative transfer effects on Doppler measurements as sources of surface effects in sunspot seismology [PDF]
, 2006 We show that the use of Doppler shifts of Zeeman sensitive spectral lines to observe wavesn in sunspots is subject to measurement specific phase shifts arising from, (i) altered height range of spectral line formation and the propagating character of p ...

Long-term adaptation and distributed detection of local network changes [PDF]
, 2010 We present a statistical approach to distributed detection of local latency shifts in networked systems. For this purpose, response delay measurements are performed between neighbouring nodes via probing.

A thorough analysis of the short- and mid-term activity-related variations in the solar acoustic frequencies [PDF]
, 2016 The frequencies of the solar acoustic oscillations vary over the activity cycle. The variations in other activity proxies are found to be well correlated with the variations in the acoustic frequencies.
