Deformation of continental crust along a transform boundary, Coast Mountains, British Columbia [PDF]

open access: yes, 2010
New structural, paleomagnetic, and apatite (U-Th)/He results from the continental margin inboard of the Queen Charlotte fault (~54°N) delineate patterns of brittle faulting linked to transform development since ~50 Ma.

Active rifting and crustal thinning along the Rivera-Cocos plate boundary as inferred from Mantle Bouguer gravity anomalies [PDF]

open access: yesGeofísica Internacional, 2004
The El Gordo graben lies within the oceanic lithosphere west of the Middle America Trench at 18.15°N, 104.7°W. This graben has been proposed to mark the southwest tip of an active zone of extension located between the Rivera and Cocos plates. The results

The Preparation of Prussian Blue in a Mortar: An Example to Teach Sustainable Chemistry with Mechanochemical Reactions

open access: yesSustainable Chemistry, 2023
Solvent-free mechanochemical reactions represent an important path towards sustainable chemistry. The preparation of Prussian blue from solid iron and hexacyanoferrate compounds by the simple use of a mortar and pestle is an easy, inexpensive, and fast ...

Tertiary-Quaternary intra-plate magmatism in Europe and its relationship to mantle dynamics [PDF]

open access: yes, 2006
Anorogenic intra-plate magmatism was widespread in Europe from early Tertiary to Recent times, extending west to east from Spain to Bulgaria, and south to north from Sicily to northern Germany. Magmatism is spatially and temporally associated with Alpine-

Extremely low long‐term erosion rates around the Gamburtsev Mountains in interior East Antarctica [PDF]

open access: yes, 2010
The high elevation and rugged relief (>3 km) of the Gamburtsev Subglacial Mountains (GSM) have long been considered enigmatic. Orogenesis normally occurs near plate boundaries, not cratonic interiors, and large‐scale tectonic activity last occurred in ...

A biophysical observation model for field potentials of networks of leaky integrate-and-fire neurons

open access: yes, 2012
We present a biophysical approach for the coupling of neural network activity as resulting from proper dipole currents of cortical pyramidal neurons to the electric field in extracellular fluid.

Detecting event-related recurrences by symbolic analysis: Applications to human language processing [PDF]

open access: yes, 2014
Quasistationarity is ubiquitous in complex dynamical systems. In brain dynamics there is ample evidence that event-related potentials reflect such quasistationary states. In order to detect them from time series, several segmentation techniques have been
