Microbial mats in dinosaur ichnocoenoses
Sedimentology, EarlyView.ABSTRACT Until now, the significance of microbial mats in preservation of dinosaur tracks and in reconstructing the palaeoenvironment in which dinosaurs roamed was rarely studied. Dinosaur tracks are commonly found close to ancient aquatic bodies where moist sediment had once allowed footstep registration.

Modelling the acoustic performance of slab tracks
, 2020 Transport is a major contributor to anthropogenic greenhouse gas emissions. Railway transport has a small footprint compared to other means of transport. This is one reason for the construction of new high-speed railway lines world-wide. These lines are often constructed using slab track technology, in which the traditional track configuration of ...

Giant Porphyry Copper Deposits Caused by a Slab Jamming in the Mantle Transition Zone
Terra Nova, EarlyView.ABSTRACT Two giant porphyry copper deposits in the Southern Central Andes formed during the Miocene–Pliocene transition when a bend in the subducting Juan de Fernández hotspot chain jammed in the mantle transition zone, causing mega‐scale slab‐kinking. This geometry implies mechanical resistance that caused East–West compression and eventually a thrust‐

The Journal of Physiology, EarlyView.Abstract figure legend Modelling β‐adrenergic stimulation in sympathetically remodelled ventricular substrates. Myocardial infarction could result in sympathetic remodelling in ventricular tissues, which affects arrhythmia dynamics. However sympathetic remodelling is challenging to control experimentally; therefore we created an ionic model that ...

Slab track systems for high-speed railways.
, 2012 In the last 40 years an increase in train speed and axle load around the world and other challenges in the conventional ballasted track system gave birth to ballastless railway track system. This study examines in depth the various slab track systems that are being used today.
