Quantifying the effects of rainfall temporal variability on landscape evolution processes

Rainfall characteristics such as intensity, duration, and frequency are key determinants of the hydro-geomorphological response of a catchment. The presence of non-linear and threshold effects makes the relationship between rainfall variability and geomorp ...

A Generalized Index for Static Voltage Stability of Unbalanced Polyphase Power Systems including Thévenin Equivalents and Polynomial Models

Mario Paolone, Andreas Martin Kettner

This paper proposes a Voltage Stability Index (VSI) suitable for unbalanced polyphase power systems. To this end, the grid is represented by a polyphase multiport network model (i.e., hybrid parameters), and the aggregate behavior of the devices in each no ...

Inequality in genetic cancer risk suggests bad genes rather than bad luck

Mats Julius Stensrud

Heritability is often estimated by decomposing the variance of a trait into genetic and other factors. Interpreting such variance decompositions, however, is not straightforward. In particular, there is an ongoing debate on the importance of genetic factor ...

Strong fiber Bragg gratings in Bi-Al co-doped H2-loaded optical fibers using CW-Ar+ laser

Hans Georg Limberger, Georgios Violakis

Bragg gratings with reflectivity > 93% were fabricated in Bi-Al co-doped H-2-loaded optical fibers. Average index changes as high as +2.5x10(-3) were obtained. Positive core stress changes indicate a compaction contribution to the total index change. ...

The Kinship or k-Index as an Antidote Against the Toxic Effects of h-Indices

Geoffrey Bodenhausen

In a bilingual paper entitled 'Bibliometrics as weapons of mass citation - La bibliometrie comme arme de citation massive',([1]) recently translated into English,([2]) we have argued that the current fashion of ranking people, papers and journals is anythi ...

Fabrication/Characterization of Fiber Gratings and Photosensitivity in Ge-Free Bi-Al-Silica Fibers - INVITED

Hans Georg Limberger, Georgios Violakis, Christian Ban

Refractive index changes up to 2.5 × 10-3 were demonstrated in H2-loaded germanium free Bi-Al-doped silica fibers using both ArF excimer and cw-Ar+-244 nm lasers. Tensile stress changes indicate clear contribution of compaction to the total index change. ...

Statistical analysis of subnanometer residual disorder in photonic crystal waveguides: Correlation between slow light properties and structural properties

Romuald Houdré, Hua Zhang, Nicolas Le Thomas, Zhaolu Diao

The authors present a statistical study of residual disorder in nominally identical planar photonic crystal waveguides operating in the slow light regime. The focus is on the role played by the subnanometer scaled residual disorder inherent to state-of-the ...

UV-Photosensitivity of Germanium-free Bi-Al Silica Fibers

Hans Georg Limberger, Christian Ban

Mean index changes up to 2.2 × 10-3 were demonstrated in hydrogen loaded germanium free Bi-Al-doped silica fibers. Tensile stress changes indicate a contribution of compaction to the total index change. ...

Three-Dimensional Negative Index of Refraction at Optical Frequencies by Coupling Plasmonic Waveguides

We identify a route towards achieving a negative index of refraction at optical frequencies based on coupling between plasmonic waveguides that support backwards waves. We show how modal symmetry can be exploited in metal-dielectric waveguide pairs to achi ...

Fair Welfare Maximization

Thomas Alois Weber, Ashish Goel

We consider the general problem of finding fair constrained resource allocations. As a criterion for fairness we propose an inequality index, termed “fairness ratio,” the maximization of which produces Lorenz-undominated, Pareto-optimal allocations. The fa ...
