A methodology for the modelling of the triggering of the vine flowering
The effect of temperature on the biological rythm of the vine is well known. Flowering is triggered when the thermal requirement is met, expressed in the form of an accumulation of daily temperature over a given threshold as from a precise date.

This work demonstrates the use of reactive laser annealing to selectively tune the epsilon‐near‐zero condition of tin‐doped indium oxide patches integrated in silicon waveguides. This postgrowth annealing technique enables flexible control over the optical constants of transparent conducting oxides (TCOs) at critical telecom wavelengths, paving the way

Spherical and Aspherical Lenses for Boosting the Performance of Terahertz Imaging Systems
This study investigates the enhancement of terahertz (THz) detection through the terajet effect using mesoscale dielectric lenses of various geometries. Spherical, aspherical, and cubic polytetrafluoroethylene lenses are evaluated at 0.15 and 0.3 THz, demonstrating significant improvements in responsivity and noise reduction.

Financing the New Economy : its Impact on Growth. [PDF]
L’exceptionnelle performance de l’économie des Etats-Unis durant les années 1990 a conduit les économistes à s’interroger successivement sur le phénomène de la nouvelle économie, la réalité de ses effets favorables et les risques qu’elle engendre.

The ability to switch the HER activity of precious metals at will through a reconfigurable step‐edge/nanoparticle interface, using sulfur as an inorganic mediator, is demonstrated for the first time. This methodology addresses the durability issue of highly catalytic precious metals, which are typically single‐use, thereby extending their lifespan ...

Les approches de l'économie sociale et de l'économie solidaire face aux mutuelles de santé en Afrique [PDF]
Ce papier examine dans quelle mesure les approches "économie sociale" et "économie solidaire" peuvent éclairer les réalités des mutuelles de santé en Afrique, mais aussi leurs limites respectives face à ces pratiques de plus en plus ...

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells
Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize
