The Depositional Record, EarlyView.The Joulters ooid sandbody of northern Great Bahama Bank is a vast expanse of muddy ooid sands partly rimmed by clean ooid sands and formed into a relatively thick layer of significant extent. Knowledge of the development of depositional and diagenetic patterns in the Joulters example has forwarded our general understanding of carbonate sedimentology ...

Fracturing behaviors of flawed granite induced by dynamic loadings: A study based on DIP and PFC
Deep Underground Science and Engineering, EarlyView.This research examines granite's mechanical properties under split‐Hopkinson pressure bar testing, focusing on factors such as grain size and flaw dimensions. The study reveals that tension cracks are prevalent across grain sizes, with most intergrain cracks occurring between feldspar and quartz.

Deep Underground Science and Engineering, EarlyView.In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type

Quantification of rheological parameters in deep‐sea mining plumes
Deep Underground Science and Engineering, EarlyView.This study explores the variations in rheological properties observed during the propagation of deep‐sea mining plumes, utilizing rheological test data obtained from kaolin clay plumes. Subsequently, taking into account the differences in sediment properties, the effects of clay content and clay mineral composition on the rheological parameters of ...

Developmental Dynamics, EarlyView.Abstract Background The avian node is the equivalent of the amphibian Spemann's organizer, as indicated by its ability to induce a secondary axis, cellular contribution, and gene expression, whereas the node of the mouse, which displays limited inductive capacities, was suggested to be a part of spatially distributed signaling.

Environmental Policy and Governance, EarlyView.ABSTRACT Climate backlash and policy dismantling, that is, the reversal of existing decarbonisation policies, can be observed in an increasing number of countries. Typically, policy change tends to be slow, while climate backlash can unfold quite fast. How is such rapid political change made possible?
