Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

open access: yesSedimentology, EarlyView.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

Ductile Extrusion Triggered by Continental Collision in NE Brazil

open access: yesTerra Nova, EarlyView.
ABSTRACT The Borborema Province in northeastern Brazil hosts one of the world's largest strike‐slip shear zone networks, active during the late Neoproterozoic assembly of West Gondwana. Whether these shear zones initiated during active continental collision or as a post‐orogenic response to far‐field stresses remains debated.

Emergence of Continents Stabilized the Bioavailability of Boron

open access: yesTerra Nova, EarlyView.
ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.

Stigma, self‐styling and ‘forced accents’ among English L2 speakers in Spain

open access: yesWorld Englishes, EarlyView.
Abstract This paper examines the relationship between shame, stigma and accent for non‐native English speakers in Spain. The low English competence of the Spanish population frequently constitutes a source of individual and collective stigma – which includes the apparent undesirability of Spanish‐sounding English.

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Pericytes are microvascular mural cells with diverse roles. Contractile pericytes directly regulate local perfusion, while non‐contractile pericytes coordinate upstream vascular contractility via propagating electrical signals.
