Calcium Isotopic Composition in Reindeer (Rangifer tarandus) Bones and Tooth Enamel: A Scalable Tool to Quantify Nursing Frequency in Past and Modern Populations?

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 23, 15 December 2026.
ABSTRACT Rationale Populations of North American caribou and Eurasian reindeer (Rangifer tarandus sspp.), essential for Arctic ecosystems and human communities, are experiencing unprecedented declines due to climate change and anthropogenic pressures. While understanding their historical resilience and demographic dynamics is critical for conservation,

Arbitrary Lagrangian–Eulerian Formulation in a Rotating Frame to Model Friction Spinning

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Friction spinning is a metal forming process that can be used to manufacture various shapes by rotating a metallic workpiece relative to a blunt tool. When used as a hot metal forming process, the relative velocity between workpiece and tool is increased until substantial heat is generated due to friction.

Procurement of Senonian Flint for Bladelets Production at the Early PPNB Site of Nahal Zahal in the Northern Negev Established for the First Time Using Chemical Composition Analysis

open access: yesArchaeometry, Volume 68, Issue 6, Page 1428-1436, December 2026.
ABSTRACT The hypotheses of Senonian flint to be a prime source of prehistoric “chalcedony” flint artefacts from the Negev Desert (Israel) was not investigated in detail thus far. By combining trace‐element profiling with statistical interpretation, ten flint items from Nahal Zahal, an Early Pre‐Pottery Neolithic B site in the northern Negev, were ...

Optimizing Charpy Impact Strength of Material‐Extruded PLA Through Layer Height, Raster Angle, and Infill Geometry

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 44, November 20, 2026.
Charpy impact performance of material‐extruded PLA is governed by the coupled effects of layer height, raster angle, and infill geometry. Full‐factorial testing identifies layer height as the dominant factor and reveals a strong layer‐height–raster‐angle interaction.

Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

open access: yesPolymer Composites, Volume 47, Issue 21, Page 19085-19107, 10 November 2026.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.
