Confined diffusion

Il Nuovo Cimento C, 1991
An equation for the unidimensional confined diffusion is proposed. The equation coincides with the well-known homogeneous equation except the presence of a source term. This term which has the form of a dipole distribution is located on a moving front which sharply separates two distinct regions.

Multi-Quanta Spin-Locking Nuclear Magnetic Resonance Relaxation Measurements: An Analysis of the Long-Time Dynamical Properties of Ions and Water Molecules Confined within Dense Clay Sediments

Magnetochemistry, 2017
Solid/liquid interfaces are exploited in various industrial applications because confinement strongly modifies the physico-chemical properties of bulk fluids.

Validation of the plasma-wall self-organization model for density limit in ECRH-assisted start-up of Ohmic discharges on J-TEXT

Nuclear Fusion, 2023
A recently developed plasma-wall self-organization model (Escande et al 2022 Nucl. Fusion 62 026001) predicts a significantly enhanced density limit, which may be attainable in tokamaks with ECRH-assisted Ohmic start-up and sufficiently high initial ...

Confining strings [PDF]

Nuclear Physics B, 1997
We propose a hypothesis that all gauge theories are equivalent to a certain non-standard string theory. Different gauge groups are accounted for by weights ascribed to the world sheets of different topologies. The hypothesis is checked in the case of the compact abelian theories, where we show how condensing monopole -instanton fields are reproduced by

Disruption prediction for future tokamaks using parameter-based transfer learning

Communications Physics, 2023
Tokamaks are the most promising way for nuclear fusion reactors. Disruption in tokamaks is a violent event that terminates a confined plasma and causes unacceptable damage to the device.

IDP-PGFE: an interpretable disruption predictor based on physics-guided feature extraction

Nuclear Fusion, 2023
Disruption prediction has made rapid progress in recent years, especially in machine learning (ML)-based methods. If a disruption prediction model can be interpreted, it can tell why certain samples are classified as disruption precursors. This allows us

Confined types

Proceedings of the 14th ACM SIGPLAN conference on Object-oriented programming, systems, languages, and applications, 1999
Sharing and transfer of object references is difficult to control in object-oriented languages. Unconstrained sharing poses serious problems for writing secure components in object-oriented languages. In this paper, we present a set of inexpensive syntactic constraints that strengthen encapsulation in object-oriented programs and ...
