Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Study on the Rule of Change of Reservoir Rocks under Subcritical Steam Effect

Energies
This paper examines the lithology, pore throat, and fluid characteristics of the reservoir in Liaohe Oilfield Block 3624, using group V rocks as an example, combining a high-temperature and high-pressure reaction still with other equipment such as a rock

Thorium Energy Futures [PDF]

, 2012
The potential for thorium as an alternative or supplement to uranium in fission power generation has long been recognised, and several reactors, of various types, have already operated using thorium-based fuels.

Fatigue Assessment of Welded Joints Subjected to Multiaxial Loading Conditions through the Effective Critical Plane Approach

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Reliable fatigue design of welded components under multiaxial loading demands local criteria able to capture both the stress gradient at the weld notches and the influence of a complex loading condition including non proportionality of the stress‐strain load history. The Effective Critical Plane (ECP) approach, based on a stress averaging over

Effectiveness of Periodic Repolishing on the Surface and Mechanical Properties of Resin‐Based CAD/CAM Materials After Different Cycles of Combined Simulated Toothbrushing and Mechanical Cycling

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This study aimed to evaluate the effectiveness of periodic repolishing on the surface and mechanical properties of resin‐based CAD/CAM materials subjected to combined mechanical cycling and simulated toothbrushing, with or without periodic repolishing.

Subcritical Bifurcations and Spatiotemporal Intermittency

, 1991
Following an analogy with bifurcation theory, we study the transition to turbulence when a local subcriticality produces sharp and localized interfaces between “laminar” and “turbulent” domains. This transition to spatiotemporal intermittency is analyzed in a variety of numerical and experimental systems and shown to be best described as a phase ...

3D assessment of the marginal and internal gap and fracture load of ceramic surveyed inlays designed for removable partial denture support: An in vitro comparative study

Journal of Prosthodontics, EarlyView.
Abstract Purpose To assess the internal and marginal gaps and the fracture load of different machinable ceramics for an inlay acting as a support for a removable partial denture. Materials and Methods Sixty extracted human teeth (first maxillary premolar) were collected (n = 10 for each group).

The Core‐Periphery Model Under Additively Separable Preferences

Journal of Regional Science, Volume 65, Issue 2, Page 378-402, March 2025.
ABSTRACT This paper reexamines Krugman's core‐periphery model by substituting his constant elasticity of substitution (CES) utility with a general additively separable utility that comprehensively captures the pro‐competitive effect while preserving the income effect.

Rethinking microtidal systems: Tidal signatures in the fluvial deposits of the Po River, Italy

Sedimentology, EarlyView.
ABSTRACT In microtidally influenced rivers, tides are generally assumed to leave virtually no signatures in the sedimentary record. However, this hypothesis has been surprisingly poorly tested using modern river analogues, which provide an opportunity to assess whether sedimentary signatures of microtidal regimes can develop in rivers that lack ...
