100 Years of Element Zero: Andreas von Antropoff's Neutronium and the Naming of the Neutron

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Congratulations to the 100th Anniversary of the publication of Andreas von Antropoff's element 0, “–“! This contribution provides a historical account of the concept of element zero and the naming of the neutron. The concept of element zero is 100 years old, having a first documented appearance in a 1926 publication by Andreas von Antropoff, while the ...

From talking tools to metahumans: social interaction, semiotic skill, and the authority of AI chatbots Des outils parlants aux métahumains : interactions sociales, compétences sémiotiques et autorité des robots conversationnels

Journal of the Royal Anthropological Institute, EarlyView.
What does it take to turn a tool into a talking tool and that into an ultimate authority? Generative artificial intelligence (GenAI) in its diverse forms, such as large language models (LLMs), is celebrated as a useful tool. But LLM‐based conversational agents, or chatbots, the software applications through which ordinary users are likely to engage ...

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe

Archaeometry, EarlyView.
ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

A Multiple Scattering-Based Technique for Isotopic Identification in Cosmic Rays

Particles
Analyzing the isotopic composition of cosmic rays (CRs) provides valuable insights into the galactic environment and helps refine existing propagation models. A particular interest is devoted to secondary-to-primary ratios of light isotopic components of CRs, the measurement of which can provide complementary information with respect to secondary-to ...

New Techniques in the Cosmic-Ray Field and Some of the Results Obtained With Them [PDF]

Physical Review, 1933
Each new field of scientific study goes through a period of development which may be likened to the development of a man child. Up to the age of six or seven a boy interests everybody intensely. In babyhood he is new and sweet and altogether charming because of the awakening qualities which bloom forth as he becomes a real person, and from then on up ...

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

PyMAP: Python-Based Data Analysis Package with a New Image Cleaning Method to Enhance the Sensitivity of MACE Telescope

Galaxies
Observations of Very High Energy (VHE) gamma ray sources using the ground-based Imaging Atmospheric Cherenkov Telescopes (IACTs) play a pivotal role in understanding the non-thermal energetic phenomena and acceleration processes under extreme ...

A bifacial paradise—The site of Ochtmissen, Germany, and its lithic assemblage in the context of the last glacial (early MIS 4) in the north‐central European Lowland

Boreas, EarlyView.
The Palaeolithic site of Ochtmissen (Lower Saxony, Germany) was excavated in fluvial terrace deposits during the winter of 1993/1994. The current study presents, for the first time, a thorough analysis of the lithic assemblage, encompassing its primary technological and typological characteristics, as well as the type and age of the fluvial deposits ...

The Search For Pulsar Wind Nebulae in the Very High Energy Gamma-ray Regime [PDF]

, 2010
The aim of this Thesis is to study the development of pulsar wind nebulae in the TeV regime and in doing so uncover more sources which have as yet not been observed at these wavelengths.

Geochemical investigation of impactites from the Boltysh impact structure and possible relationship to early Danian sediments from the Umbria–Marche Basin, Italy

Meteoritics &Planetary Science, EarlyView.
Abstract Within the Danian Scaglia Rossa Formation appears a regionally correlatable horizon cutting across multiple sections and outcrops within the Umbria–Marche Basin of NE Italy, where it is intercalated with uniform pelagic carbonate successions. This horizon is called “ALE layer” and has tentatively been interpreted as a fine‐grained volcanic ash.
