Quantification of dryland depositional environments across contrasting fluvio‐aeolian and fluvio‐lacustrine transects: An integrated subsurface and outcrop analogue study of the Organ Rock Formation, Utah, USA

open access: yesSedimentology, EarlyView.
ABSTRACT The standard subdivision of a distributive fluvial system (DFS) into proximal, medial and distal zones is typically based on the proportion of channel bodies and/or the degree of channel amalgamation, reflecting a downstream fining trend towards a mud‐prone terminal pinch‐out.

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3091-3105, November 2026.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

A New Design of the Tooth Profile for Single Screw Compressors [PDF]

open access: yes, 2012
The wear of star wheel teeth is an importance issue in the single screw compressor. In order to enhance the wearresistance of star wheel teeth, some new profiles of the meshing pair were proposed to replace the currently used straight line envelope ...

Identification Method for Instantaneous Friction and Wear Energy Density Variation of High-Feed Milling Tool Flank

open access: yes, 2023
Instantaneous friction and wear energy density are important indicators of the friction and wear state of the tooth flank of the milling cutter. Existing methods for identifying the friction and wear on the tooth flank of milling cutters mainly focus on ...

Cooling Holes in Polymer Spur Gears: A Critical Analysis of Heat Dissipation Benefits and Mesh Stiffness Penalties

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 38, October 10, 2026.
Cooling holes provide a simple passive cooling strategy for polymer spur gears, reducing maximum operating temperature by up to 9.39% while introducing a measurable gear mesh stiffness penalty. A validated response‐surface model reveals how hole size and location govern this thermal–mechanical trade‐off, enabling design optimization for thermally and ...

Heat Treatment and Manufacturing Variability in Gearbox NVH: An Evidence‐Aware Critical Review and Validation‐Oriented Modeling Roadmap

open access: yesEngineering Reports, Volume 8, Issue 10, October 2026.
Heat treatment and manufacturing variability influence gearbox NVH primarily through distortion, surface integrity, and evolving tooth‐flank geometry. This evidence‐aware review links material state and nonuniform wear to contact excitation, transmission error, structural response, and radiated noise within a validation‐oriented multiscale framework ...

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.

Marine Geophysical Investigation of a Fault Ruptured During the 2012 Mw 8.6 Wharton Basin Earthquake

open access: yesTectonics, Volume 45, Issue 10, October 2026.
Abstract The 2012 Mw 8.6 and 8.2 Wharton Basin earthquakes, within an intraplate deformation zone in the Indian Ocean, are the largest instrumentally recorded strike‐slip earthquakes on Earth that challenged the prevailing view that great earthquakes occur only at well‐defined plate boundaries.

Hierarchical Assembly as a Design Principle: Structure–Property Relationships Linking Biological Architectures to Functional Aggregate Materials

open access: yesAggregate, Volume 7, Issue 9, September 2026.
Biological function arises from aggregates rather than from molecules. Comparing biomimetic systems on a common basis reveals three transferable design rules governing hierarchical assembly, interfacial gradients, and stimulus‐coupled anisotropy, and identifies self‐healing and single‐step multiscale integration as properties that do not transfer to ...
