The Week is to give away 100,000 free copies on Friday to mark its 20th anniversary in the largest sampling campaign the weekly news digest's history.
This is now joined by "I Promise to Be Good: The Letters of Arthur Rimbaud," the largest sampling of the poet's correspondence yet to appear in English.
Reflectance and spectral contrast were good predictive tools of total plant species richness at the largest sampling scale, but their predictive power diminished at the smaller scales.
At the largest sampling scale (100 m2), the highest variability of species richness was adequately related to the spectral and texture responses, due to the spatial fit between the sampling plot size and both the pixel- and plant-sizes.
Using the notion of cooperative systems, we show that the solutions of the observers converge to the solutions of the original system, under conditions on the nonlinear terms and on the largest sampling interval.
We use a new Lyapunov approach to derive conditions on the largest sampling interval and on the delay length to ensure asymptotic stabilization properties of a componentwise positive equilibrium point.
