Valuing critical zone services in intensively managed landscapes
The critical zone (CZ) includes the range of biophysical processes occurring from the top of the vegetation canopy to the weathering zone below the groundwater table. CZ services provide a measure to value processes that support the goods and services from landscapes. In intensively managed …

Influence of bulk defects in p-type Czochralski silicon on reliability of high efficiency solar cells
… We show that under light exposure, boron-doped Cz Si transitions from paramagnetic to diamagnetic via the creation of ~1016 cm-3 shallow hole traps, in which ~1012 cm-3 are the recombination active LID defect. Additionally, we find that both boron and oxygen are required for the transition from …

Using event-related potentials to monitor the time course of mental processing during eye fixations in reading
… conditions at each of four recording sites (Cz, Pz, P$\sb3$, and P$\sb4$) were compared to see how soon, after the beginning of the initial fixation on a critical word location, they separated. The earliest point in time at which control and orthographic grand averages separated as a result …

The asymptotic behavior of the integer solutions of the Rosenberger equations
… are equations of the form: ax 2 + by2 + cz 2 = dxyz, where the sets of coefficients ( a, b, c, d) are all integers such that each of a, b, and c divides d, and the equations themselves have infinitely many integer solutions. Rosenberger has shown that there are only six such sets of …
