New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Models of DG‐Carbon Bands in Raman Spectra: Effects of Basis Functions and Initial Values on the Uniqueness and S/N of Fits Obtained for Atmospheric Aerosol Using Automated Methods

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman spectra containing D/G features are fit using combinations of basis functions and initial conditions. Fits with two Lorentzian functions converged to a single optimized fit even with variation of initial peak positions. For five‐band fits, sometimes the final fit varied with initial conditions, and constraints on peak center position were ...

Robust Spectroscopic Analysis Through Image‐Based Spectral Representation and Deep Learning Techniques

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study addresses calibration drift in Raman spectroscopy by transforming 1D spectra into 2D spider plot images processed by pretrained convolutional neural networks. This visualization strategy effectively converts detrimental spectral wavenumber shifts into simple image rotations, allowing the deep learning model to maintain high classification ...

Zero‐Dimensional Perovskite‐Inspired Scintillator‐Based High‐Radiation‐Resistant Radionuclide Analyzer Free From Irreversible Degradation

open access: yesLaser &Photonics Reviews, EarlyView.
A zero‐dimensional perovskite‐inspired scintillator (Cs3Cu2I5) is developed as a high‐radiation‐resilient radionuclide analyzer capable of operating under extreme γ‐ray environments. Even after 200 kGy irradiation, the device fully restores its original spectroscopic performance through simple thermal annealing, demonstrating intrinsic defect ...

Scaling Relations of Galactic Outflows across Cosmic Time: New Insights from Cosmic Noon

open access: yesThe Astrophysical Journal
Galactic outflows play a significant role in regulating galaxy evolution. Scaling relations between stellar mass ( M _⋆ ), star formation rate (SFR), and outflow properties have been extensively studied at low redshifts ( z   50 for H α or [O iii ] λ ...

Molecular, spatial, and AI‐enabled technologies for predicting neoadjuvant therapy response in locally advanced rectal cancer

open access: yesThe Journal of Pathology, EarlyView.
Abstract Pretreatment prediction of neoadjuvant response remains an unresolved challenge in locally advanced rectal cancer, where management is moving towards risk‐adapted and response‐oriented treatment strategies. Prediction remains difficult because response reflects interacting tumour‐intrinsic, immune, stromal, and spatial processes that are ...

The Cosmic Evolution of Giant Radiosources

open access: yes, 1998
We describe the first complete sample of giant (D ∼ 1 Mpc) radiosource selected at high redshift. Contrary to previous expectations, such sources remain common in the population at least out to z ≈ 1. We find that giants exist exclusively in low density environments, and we discuss the implications of the existence of such environments at high redshift

Increasing urban flash flood risk attributable to both climate and development

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
A new event impact attribution methodology that combines convection‐permitting climate model data with flood inundation modelling was used for a five‐hour flash‐flooding event in the suburbs of Leeds in 2014. The results show increased urban flood extent due to both climate change (+16%) and increased urbanisation (+29%).
