The Early Upper Palaeolithic open‐air site of Friedrichsdorf‐Seulberg, Germany, in the context of the northern central European Aurignacian

open access: yesBoreas, EarlyView.
Our knowledge of the Early Upper Palaeolithic occupation in northern central Europe is very limited, and recent research at the open‐air site of Friedrichsdorf‐Seulberg in Hesse, Germany, provides important new information on the Aurignacian. The site is rather small (26.5 m2) and spatial analysis identified a central hearth with two associated ...

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

open access: yesCladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

A calculation model for rating the gear load capacity based on local stresses and local properties of the gear material

open access: yes, 2022
S.87-98The paper presents a material-physically based model for calculating the load capacity of gears taking into account the different stress conditions in the tooth root and on the tooth flank and considering decisive material properties due to ...

Application of close‐kin mark–recapture to an American black bear population using harvest samples

open access: yesEcological Applications, Volume 36, Issue 7, October 2026.
Abstract Close‐kin mark–recapture (CKMR) offers a promising alternative to traditional mark–recapture methods for estimating wildlife population parameters. CKMR estimates demographic parameters by identifying genetic relationships between individuals, effectively “recapturing” parental genotypes through their offspring's genetic profiles.

Myelination and Remyelination in Peripheral Nerve Injury: Mechanisms, Regulation, and Therapeutic Perspectives

open access: yesMedComm, Volume 7, Issue 10, October 2026.
Peripheral nerve injury triggers axonal degeneration, myelin breakdown, and Schwann cell reprogramming. Remyelination requires reactivation of the SOX10–OCT6–KROX20/EGR2 transcriptional hierarchy, axonal NRG1–ErbB2/3 signaling, metabolic support, and coordinated immune regulation.

Earthquakes and the Metamorphic Sole of the Tinos Ophiolite, Cyclades, Greece

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract We analyze deformation fabrics, compositions of melts, metamorphic temperatures, and paleopiezometric data beneath the Tsiknias Thrust, Tinos, Greece, which formed part of the plate boundary that, in Late‐Cretaceous time, absorbed convergence between Africa and Europe associated with final closure of the Vardar Ocean.

Total‐evidence phylogenetics and taxonomy of the Paederinae (Coleoptera, Staphylinidae) rove beetle fossils in Baltic amber sensu lato for palaeoclimate research

open access: yesPapers in Palaeontology, Volume 12, Issue 5, September/October 2026.
Abstract Baltic amber s.l., the most abundant amber deposit of insect fossils, is essential for understanding the palaeoenvironment of the Eocene, an epoch characterized by severe climate changes, including the warmest period in the entire Cenozoic. The ecological requirements of the extinct lineages can be deduced from the ecology and distribution of ...

On the Mutual Relation Between Contact Ratio and Crack Propagation in the Tooth Root of Spur Gears

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 9, Page 3896-3908, September 2026.
ABSTRACT This work investigates the mutual relationship between contact ratio and tooth root crack propagation in spur gears, with particular focus on the influence of meshing stiffness and load sharing on the tooth root lifetime. An experimental case study originally reported by Rettig, in which SN curves of gears with similar geometry but different ...

Apparatus architecture of Pseudofurnishius murcianus (Gondolellidae, Conodonta) and its implications for the evolution of the conodont skeleton

open access: yesPalaeontology, Volume 69, Issue 5, September/October 2026.
Abstract Conodonts are known primarily from their microscopic tooth‐like skeletal feeding elements that occur commonly in jumbled assemblages in marine rocks from the late Cambrian to the Triassic–Jurassic boundary interval. Interpreting their evolution requires a scheme of positional homology of these elements within the feeding apparatus, information

Tooth Flank Mismatch Meshing Analysis for Spiral Bevel Gear Based on Tilt Cutting Method

open access: yes, 2019
The analysis method of tooth flank mismatch meshing is studied for the spiral bevel gear of automobile drive axle. Firstly,the mathematical model of tilt cutting method is established,and the cradle angle is derived according to the meshing equation,so ...
