Upland soils have been identified as a major CO 2 source induced by human activities, such as fertilizer applications. The aim of this study is to identify the characteristics of soil CO 2 emission and carbon balance in cropland ecosystems after cont

Data from the Pierre Auger Observatory are analyzed to search for anisotropies near the direction of the Galactic Centre at EeV energies. The exposure of the surface array in this part of the sky is already significantly larger than that of the fore-

An upper limit to the photon fraction in cosmic rays above 1019 eV from the Pierre Auger Observatory
An upper limit of 16% (at 95% c.l.) is derived for the photon fraction in cosmic rays with energies greater than 1019 eV, based on observations of the depth of shower maximum performed with the hybrid detector of the Pierre Auger Observatory. This is

A novel, temperature-independent strain sensor is demonstrated using a chirped fibre grating in a tapered optical fibre. The effective bandwidth of the grating is uniquely dependent on strain and is essentially temperature-independent. The interrogat

We demonstrate the enhancement of optical bandwidth for modulators based on the quantum confined Stark effect using high barrier multiquantum well structures. This is achieved by carefully placing the Fabry-Perot mode in the wavelength region where t

In this paper, we propose a versatile and compact mechanism for tunable grating dispersion. A segmented piezoelectric stack with individually controlled segments was used to control the local strain at 21 positions along the grating. By step-wise mon
