“Unifying” the Concept of Resource Use Efficiency in Ecology

Frontiers in Ecology and Evolution, 2019
Resource use efficiency (RUE) is an ecological concept that measures the proportion of supplied resources, which is converted into new biomass, i.e., it relates realized to potential productivity.

Assessing Land Degradation/Recovery in the African Sahel from Long-Term Earth Observation Based Primary Productivity and Precipitation Relationships [PDF]

, 2013
The ‘rain use efficiency’ (RUE) may be defined as the ratio of above-ground net primary productivity (ANPP) to annual precipitation, and it is claimed to be a conservative property of the vegetation cover in drylands, if the vegetation cover is not ...

Thermoelectric Properties of a Family of Benzodifuranone‐Based Conjugated Copolymers in Oriented Thin Films Doped Sequentially With NDMBI‐H

Advanced Electronic Materials, EarlyView.
Combining high polymer orientation of n‐type copolymers by temperature rubbing and sequential doping with N‐DMBI results in a strong improvement of electrical conductivity and thermoelectric power factors reaching up to 9.8 ± 1.6 S cm−1 and 8 ± 3 µW m−1.K2, respectively.

La mémoire de la Grande Guerre à travers les odonymes en France

EchoGéo
The living memory of the past can be measured by the management of odonyms (route and place names). The presence of the Great War in France by studying of the actual FANTOIR file is significant. But the number of odonyms who commemorates the second world

Improving the INLA approach for approximate Bayesian inference for latent Gaussian models

, 2015
We introduce a new copula-based correction for generalized linear mixed models (GLMMs) within the integrated nested Laplace approximation (INLA) approach for approximate Bayesian inference for latent Gaussian models.

Analysis of resonant responses of split ring resonators using conformal mapping techniques [PDF]

, 2007
We report a novel method for modeling the resonant frequency response of infra-red light, in the range of 2 to 10 microns, reflected from metallic spilt ring resonators (SRRs) fabricated on a silicon substrate.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

Advanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.
