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.

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.

Psychological consequences of COVID-19 home confinement: The ECLB-COVID19 multicenter study

PLoS ONE, 2020
Background Public health recommendations and government measures during the COVID-19 pandemic have enforced restrictions on daily-living. While these measures are imperative to abate the spreading of COVID-19, the impact of these restrictions on mental ...

Testing of ITER-grade plasma facing units in the WEST tokamak: Progress in understanding heat loading and damage mechanisms

Nuclear Materials and Energy, 2023
Assessing the performance of the ITER design for the tungsten (W) divertor Plasma Facing Units (PFUs) in a tokamak environment is a high priority issue to ensure efficient plasma operation.

Layer-structured Cr/Cr x N coating via electroplating-based nitridation achieving high deuterium resistance as the hydrogen permeation barrier

Journal of Advanced Ceramics, 2022
Hydrogen isotope permeation through structural materials is a key issue for developing nuclear fusion energy, which will cause fuel loss and radioactive pollution.

Interatomic collisions in a tightly confined Bose gas [PDF]

Phys. Rev. A 64, 012706 (2001), 2000
We discuss pair interatomic collisions in a Bose gas tightly confined in one (axial) direction and identify two regimes of scattering. In the quasi2D regime, where the confinement frequency $\omega_0$ greatly exceeds the gas temperature $T$, the scattering rates exhibit 2D features of the particle motion.

Plasma exposure of a pre-damaged ITER-like plasma facing unit in the WEST tokamak: in-situ and post-mortem measurements

Nuclear Materials and Energy, 2023
The consequences of tungsten (W) cracking on divertor lifetime and plasma operation are high priority issues for ITER. One actively cooled ITER-like plasma facing unit (PFU) has been pre-damaged in a High Heat Flux (HHF) facility before its installation ...

Large center vortices and confinement in 3D Z(2) gauge theory [PDF]

Phys.Rev.D66:017501,2002, 2002
We study the role of large clusters of center vortices in producing confinement in 3D Z(2) gauge theory. First, we modify each configuration of a Monte Carlo-generated ensemble in the confined phase by removing the largest cluster of center vortices, and show that the ensemble thus obtained does not confine. Conversely, we show that removing all of the

Monopole Condensation in Lattice SU(2) QCD [PDF]

, 1995
This is the short review of Monte-Carlo studies of quark confinement in lattice QCD. After abelian projections both in the maximally abelian and Polyakov gauges, it is seen that the monopole part alone is responsible for confinement.
