Numerical Modeling of the Thermo‐Mechanical and Electrical Behavior of a Sensor‐Integrating Jaw Coupling

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Industry 4.0 requires more and more data from the production process, for example, on transmitted forces, torques and wear, in order to reduce expensive downtimes and to increase productivity. Direct or indirect methods can be used to collect this data.

Late Jurassic Carbon Isotope Excursion (Middle Oxfordian Event) Paces With Astronomical Forcing in the Northwestern Tethys

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Marine carbonate carbon isotopes (δ13C), over orbital to multi‐million‐year timescales, provide critical insight into the carbon cycle connecting Earth's atmosphere, lithosphere, hydrosphere and biosphere. However, the influence of astronomical forcing on deep time carbon cycle dynamics remains poorly constrained.

Bone Anvils and New Types of Osseous Tools at Walīla (Volubilis, Morocco): Use of Animal Byproducts in the Industries of a Medieval Town

International Journal of Osteoarchaeology, Volume 36, Issue 3, Page 728-742, May/June 2026.
ABSTRACT Bone anvils used to sharpen metal sickle blades are frequently documented in the archaeological record of the Roman and medieval Mediterranean and beyond, with new finds reported each year. This article reports anvils from the early medieval town of Walīla (Roman Volubilis) in northern Morocco and presents two other types of bone tools (bone ...
