Insights From the Alphasat Aldo Paraboni Experiment at Tito Scalo and Spino d'Adda: Characterizing Scintillation and Rain Attenuation at Ka‐ and Q‐Band Frequencies

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT We present experimental results on the relationship between rain attenuation and simultaneous scintillation during rain events, based on beacon signal measurements at 19.7 (Ka‐band) and 39.4 GHz (Q‐band) from the geosynchronous Alphasat satellite (25° E), received at two Italian ground stations, Spino d'Adda (42.1° slant path) and Tito Scalo ...

Eutectic Mixtures of Inorganic and Organic Adamantane‐Type Compounds With Strongly Nonlinear Optical Properties

Small, EarlyView.
ABSTRACT We report a new concept to lower the melting temperature (Tm) of inorganic‐organic hybrid adamantane‐based cluster compounds by forming unprecedented eutectic cluster mixtures with organic adamantane derivatives. Blending of clusters of the type [(p‐MeC6H4Si(CH2SnPhE)3] (E = S, Se, Te) with (3‐F‐4‐Me‐C6H3)3Ad, (3‐F‐4‐Me‐Ph)4Ad, and (4‐MeO‐C6H4)

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 ...

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Region‐of‐interest geometry optimization for shooting‐distance estimation from flash‐pulse infrared thermography of gunshot residue on textile targets

Journal of Forensic Sciences, EarlyView.
Abstract Shooting‐distance estimation from gunshot‐residue (GSR) patterns on textiles is affected by substrate properties, residue distribution, and region‐of‐interest (ROI) definition. This study evaluated how ROI geometry influences muzzle‐to‐target distance regression from flash‐pulse infrared thermography of GSR‐related thermal patterns.

Divergence Linked to Possible Ecological Speciation in Blind Mole Rats: Integration of Thermal Biology and Bite Force in the Upper Galilee Blind Mole Rat (Nannospalax galili)

Integrative Zoology, EarlyView.
Basalt‐dwelling blind mole rats maintain lower body temperatures, show greater post‐digging thermal increases, and dig more efficiently than those from rendzina soils. Although metabolic rates and bite force did not differ between populations, these thermal and physiological shifts align with the greater mechanical resistance and seasonal hypoxia of ...

Biometric Analysis of Giant and Large Murid Remains From Matja Kuru 2, Timor‐Leste

Archaeometry, EarlyView.
ABSTRACT Published research on Matja Kuru 2 (MK2) demonstrates its significance for understanding human lifestyle during the terminal Pleistocene and Holocene. Murids represent the most commonly identified taxa in the site, with specimens preliminarily classified as small, large and giant based on size comparisons.
