which can be represented through a plot of in-phase (I) and quadrature (Q) vectors also known as a constellation diagram, as shown in Figure 1a. In general, EVM is calculated by finding the ideal constellation location
The magnitude and phase angle of a signal can be described by these real and imaginary components. If we plot a complex-valued F(u) in a polar coordinate form (Re, Im), then the magnitude is the Euclidean distance between the center and the plotted point. The phase angle θ is the am...
Globally, we estimate 1430 (95% credible interval: 1327–1544) bird extinctions since the Late Pleistocene (Fig.2a). Given current estimates of 10,865 extant bird species, this suggests that 11.6% (10.9–12.4) of all bird species (approximately one in nine) have gone extinct over the last ...
Atmospheric conditions affect the release of anemophilous pollen, and the timing and magnitude will be altered by climate change. As simulated with a pollen emission model and future climate data, warmer end-of-century temperatures (4–6 K) shift the
Interest in small-to-medium magnitude earthquakes and their potential consequences has increased significantly in recent years, mostly due to the occurrence of some unusually damaging small events, the development of seismic risk assessment methodologies for existing building stock, and the recognition of...
