How digitisation of herbaria reveals the botanical legacy of the First World War

PLANTS, PEOPLE, PLANET, EarlyView.
Digitisation of herbarium collections is bringing greater understanding to bear on the complexity of narratives relating to the First World War and its aftermath – scientific and societal. Plant collecting during the First World War was more widespread than previously understood, contributed to the psychological well‐being of those involved and ...

A fibered laser system for the MIGA large scale atom interferometer

Scientific Reports, 2020
We describe the realization and characterization of a compact, autonomous fiber laser system that produces the optical frequencies required for laser cooling, trapping, manipulation, and detection of 87Rb atoms - a typical atomic species for emerging ...

Kinship through code, personhood as node: AI afterlives and new technologies of the self Parenté par le code, personne nodale : vie posthume dans l'IA et nouvelles technologies du moi

Journal of the Royal Anthropological Institute, EarlyView.
This article examines how emerging generative AI technologies in Europe and North America are being used to reanimate the dead, prompting users to define the ‘edges’ of self and personhood through coding practices. These technologies invite new engagements with fundamental questions of relatedness and the construction of the self, challenging and ...

Revisiting Temporal Coupled-Mode Theory in Ultrafast Physics: An Ab-initio Approach [PDF]

EPJ Web of Conferences
We employ an ab initio Maxwellian approach using quasinormal-mode theory to derive an “exact” Maxwell evolution (EME) equation for resonator dynamics. The new differential equation bears resemblance to the classical one found in coupled-mode-theory (CMT);

Scale‐robust fibre orientation analysis of hair using two‐dimensional Fourier transform

International Journal of Cosmetic Science, EarlyView.
We present a simple and robust method to quantify hair fibre orientation using 2D‐DFT. It works with standard images and extracts directional features at multiple scales. This enables objective evaluation of cosmetic treatments and product effects. Abstract Objective To address the current lack of standardized tools for evaluating hair appearance in ...
