Scale-dependence of lithological control on topography: Bedrock channel geometry and catchment morphometry in western Scotland [PDF]

, 2010
We propose that a scale-dependent topographic signature of erodibility arises due to fluvial and glacial erosion acting on different parts of the landscape at different times.

Commentary: The missing sabertooth baculum—At what point might the absence of evidence reasonably be considered evidence of absence?

The Anatomical Record, EarlyView.
Abstract Most carnivorans and all modern felids have ossified bacula; however, no machairodont baculum has ever been identified. This is true despite the many fairly complete skeletons found around the world of several sabertooth taxa. Although the bacula of modern felids are much smaller than those of canoids (even the least weasel's baculum is longer

Deformation in Moffat Shale detachment zones in the western part of the Scottish Southern Uplands [PDF]

, 2004
A study of the décollement zones in the Moffat Shale Group in the Ordovician Northern Belt of the Southern Uplands of Scotland reveals a progressive sequence of deformation and increased channelization of fluid flow.

Inferring Fault Frictional and Reservoir Hydraulic Properties From Injection‐Induced Seismicity

Geophysical Research Letters, 2018
Characterizing the rheological properties of faults and the evolution of fault friction during seismic slip are fundamental problems in geology and seismology.

Determining Earthquake Susceptible Areas Southeast of Yogyakarta, Indonesia—Outcrop Analysis from Structure from Motion (SfM) and Geographic Information System (GIS)

Geosciences, 2018
Located approximately a hundred kilometres north of Java Subduction Zone, Java Island has a complicated geology and geomorphology. The north zone is dominated by the folded area, the centre is dominated by the active volcanic arc and the south of Java ...

Quantitative Analysis and Evaluation of Coal Mine Geological Structures Based on Fractal Theory

Energies, 2021
With the increasing depth of coal mining, the quantitative evaluation of the degree of geological structure development is becoming increasingly important for the control of mine water hazards in coal mining areas.

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

The Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

A comparison of Landsat 8 (OLI) and Landsat 7 (ETM+) in mapping geology and visualising lineaments: A case study of central region Kenya

, 2015
Availability of multispectral remote sensing data cheaply and its higher spectral resolution compared to remote sensing data with higher spatial resolution has proved valuable for geological mapping exploitation and mineral mapping.
