Hybrid Resolution Method for Efficient Depletion Analyses using Explicit Geometry Multigroup Monte Carlo [PDF]

EPJ Web of Conferences
The hybrid resolution (HR) method is a recently developed calculational algorithm tailored for efficient nuclear reactor analysis by leveraging multigroup (MG) Monte Carlo (MC) coupled with continuous energy MC calculations.

CASTRO: A New Compressible Astrophysical Solver. II. Gray Radiation Hydrodynamics

, 2011
We describe the development of a flux-limited gray radiation solver for the compressible astrophysics code, CASTRO. CASTRO uses an Eulerian grid with block-structured adaptive mesh refinement based on a nested hierarchy of logically-rectangular variable ...

Maternal exercise improves vascular function in hypertensive offspring via A‐kinase anchoring protein 150 gene (Akap5) epigenetic modifications

British Journal of Pharmacology, Volume 183, Issue 10, Page 2592-2612, May 2026.
Background and Purpose Regular physical activity is an effective non‐pharmacological approach to hypertension management and maternal exercise improves offspring cardiovascular health, although mechanisms remain unclear. A‐kinase anchoring protein 150 (AKAP150) targets protein kinase Cα to L‐type Ca2+ channels (CaV1.2), enhancing vascular tone in ...

A Cross‐Cultural Study of Different Types of Shyness: Associations With Depression and Aggression in Canadian and Chinese Children

Social Development, Volume 35, Issue 2, May 2026.
ABSTRACT Previous studies have shown that the expression of childhood shyness varies across Western and Eastern cultures. This study examined whether two East Asian subtypes of shyness (anxious and regulated) existed in both a Western and East Asian context; and if so, whether there were differences in the relation between these two subtypes and ...

Development of an Analytic Nodal Diffusion Solver in Multigroups for 3D Reactor Cores with Rectangular or Hexagonal Assemblies. [PDF]

, 2009
More accurate modelling of physical phenomena involved in present and future nuclear reactors requires a multi-scale and multi-physics approach. This challenge can be accomplished by the coupling of best-estimate core-physics, thermal-hydraulics and ...

A genetic algorithm to optimize the multi-group structure for the neutronic analyses of the ARC fusion reactor

Nuclear Materials and Energy
In the framework of the modeling of fusion reactors with deterministic neutronic codes, the choice of an appropriate energy grid for the generation of the multigroup nuclear properties is essential.

The consequences of nuclear electron capture in core collapse supernovae

, 2003
The most important weak nuclear interaction to the dynamics of stellar core collapse is electron capture, primarily on nuclei with masses larger than 60. In prior simulations of core collapse, electron capture on these nuclei has been treated in a highly
