Sensorial and nutritional qualities of muscles from cross‐bred Salers heifers raised on mid‐mountain pasture

open access: yesJSFA reports, EarlyView.
Abstract Background This study investigated the effects of crossbreeding, finishing system, and muscle type on carcass characteristics, intramuscular fat (IMF), image‐based IMF estimation, fatty acid composition, and meat quality in beef heifers. Charolais × Salers (C × S) and Angus × Salers (A × S) crossbred heifers were finished either on pasture or ...

Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin‐Film Crystals

open access: yesLaser &Photonics Reviews, EarlyView.
The concept of geometric phase matching is demonstrated as a dynamically reconfigurable approach for tunable nonlinear wave mixing in multilayered nonlinear thin‐film crystals. Experimental results reveal full modulation in a bilayer structure and near‐perfect spin‐selective phase matching of second‐harmonic generation in an eight‐layer configuration ...

Time‐Modulated Optomechanics Reveal Energy Flow and Inelastic Interactions Between Acoustic Phonons in Nanomembranes

open access: yesLaser &Photonics Reviews, EarlyView.
Temporal interfaces are abrupt refractive index changes used in time‐varying optics, but also transitions to nonequilibrium states. This work explores the inelastic scattering of time‐varying light by nonthermal acoustic phonons in the vicinity of temporal interfaces.

Lightning electromagnetic emission location using arrival time differencing (LEELA): An introduction to the Met Office's next generation Very Low Frequency lightning location system

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This paper describes the Met Office's new lightning location system LEELA. A brief overview of the upgraded hardware and geolocation algorithms is given. LEELA has improved lightning detection capabilities, especially at night. When comparing LEELA to the previous ATDnet system against ground truths LEELA has 100% storm detection efficiency within 5 km

Enhancing severe convection forecasts with microwave radiance assimilation in limited‐area models

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Microwave satellite radiances remain largely underexploited in convection‐permitting limited‐area models. We assess the assimilation of humidity‐sensitive radiances from the MHS instrument in the operational ICON‐2I model, improving the precipitation forecast of a severe convective event over the Marche region, Italy, substantially by correcting ...
