Pebble Bed Micro Model system identification

open access: yes, 2012
Linear system identification techniques will be applied to obtain mathematical models of a simulation of the Pebble Bed Micro Model (PBMM). The PBMM is a conceptual model of the Pebble Bed Modular Reactor (PBMR), a new high temperature gas nuclear reactor.

A percolation theory-based approach for analyzing fluid flow mechanism in blanket pebble beds

open access: yesNuclear Materials and Energy
Blanket pebble beds consist of numerous small-diameter particles, posing significant challenges for traditional simulation methods in terms of modeling accuracy and computational efficiency.

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

open access: yesSedimentology, Volume 73, Issue 6, Page 2417-2453, October 2026.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

Evidence for the continental origin of Pliocene deposits in the central Baja California peninsula, Mexico, and implications for controls on biodiversity

open access: yesSedimentology, Volume 73, Issue 6, Page 2488-2518, October 2026.
ABSTRACT Previous studies have documented genetic divergence within the last few million years between northern and southern populations of terrestrial plants and animals along the Baja California peninsula, with many studies hypothesising that the divergence is due to an ancient seaway that crossed the central peninsula and created a physical barrier ...

A Shallow‐Marine Ecosystem Before Initial Tibetan Plateau Uplift

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The uplift of the Tibetan Plateau profoundly influences global atmospheric circulation, sediment transport, and biodiversity, but its pre‐uplift marine paleoenvironment remains poorly understood. Here we report the first discovery of an in situ benthic fossil assemblage from the Puga area in central Tibet, which was deposited on a shallow ...

Early Eocene Compressional Deformation in the Northeastern Tibetan Plateau Recorded by Magnetic Fabrics of the Longzhong Basin

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Intracontinental deformation records how early Eocene India–Asia collisional stress propagated into continental interiors. How rapidly compression reached the far field, and whether coeval Paleo‐Pacific slab dynamics contributed, remain debated. The Longzhong Basin, ∼1,900 km north of the collisional zone, provides a key test.

Spatio‐Temporal Dynamics of Asian Clams in Two Mediterranean Canals

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT The rapid spread of the non‐native invasive Asian clam (Corbicula spp.) has been linked to the catastrophic decline of native freshwater mussel assemblages in Europe and North and South America. This study evaluates the spatio‐temporal dynamics and shell size structure of the Asian clam within two Mediterranean canals: Canal Imperial de Aragón
