Regional Prediction of Soil Nutrient Availability and Management Using Portable X‐Ray Fluorescence Spectrometry

X-Ray Spectrometry, EarlyView.
ABSTRACT Portable x‐ray fluorescence (pXRF) spectroscopy has emerged as a rapid and cost‐effective technique for soil elemental analysis; however, its application for predicting available nutrients and supporting agronomic decision making remains insufficiently evaluated under field conditions.

A Multi‐Analytical Campaign on Reused Medieval Musical Parchment From the Archivio di Stato di Siena (Italy)

X-Ray Spectrometry, EarlyView.
ABSTRACT In this study, a non‐invasive, multi‐analytical approach combining hypercolorimetric multispectral imaging (HMI), stereomicroscopy, X‐ray fluorescence (XRF) spectroscopy, principal component analysis (PCA) and X‐ray radiography (RX) is used to investigate three reused musical parchment fragments dating from the late 14th or early 15th century ...

Faster and targeted raster imaging through non‐rectangular scanning

Journal of Applied Crystallography, EarlyView.
A highly efficient algorithm for raster scanning an area of non‐rectangular shapes is presented. This method can significantly reduce the required scanning time for e.g. microbeam X‐ray diffraction and X‐ray fluorescence scanning microscopy.Many materials are spatially heterogenous and it is important to characterize this heterogeneity, which can be ...

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

An Overview of the Rock Art of AlUla: Tracing Changes in Content and Form Across 12,000 Years of Human History

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Between 2018 and 2021, the Identification and Documentation of Immovable Heritage Assets (IDIHA) Project recorded over 19,000 rock art panels in the AlUla (al‐‘Ulā) region of north‐western Saudi Arabia. This study presents a chronological assessment of the corpus, drawing on superimpositions, datable motifs, inscriptions, and varnish formation,
