Effects of complex symmetry-breakings on alpha particle power loads on first wall structures and equilibrium in ITER [PDF]

, 2011
Within the ITPA Topical Group on Energetic Particles, we have investigated the impact that various mechanisms breaking the tokamak axisymmetry can have on the fusion alpha particle confinement in ITER as well as on the wall power loads due to these ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Reconstructing PSP/ISOIS Pitch-angle-resolved Intensities Using Unsupervised Learning

The Astrophysical Journal
The Integrated Science Investigation of the Sun (IS⊙IS) on board the Parker Solar Probe provides high-resolution measurements of energetic particles across a broad energy range. Of particular interest are the pitch-angle distributions (PADs), which offer

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

ICRF heating schemes for the HL-2M tokamak

Nuclear Fusion, 2023
The HL-2M tokamak is a new medium-sized tokamak at SouthWestern Institute of Physics. Two of its key missions are to achieve 10 keV ion temperature and investigate the behavior of energetic particles relevant to burning plasmas.

Time distributions of solar energetic particle events: Are SEPEs really random?

, 2009
Solar energetic particle events (SEPEs) can exhibit flux increases of several orders of magnitude over background levels and have always been considered to be random innature in statistical models with no dependence of any one event on the occurrence of ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Measurement of fast ion life time using neutron diagnostics and its application to the fast ion instability at ELM suppressed KSTAR plasma by RMP

Nuclear Engineering and Technology, 2019
The confinement degradation of the energetic particles during RMP would be a key issue in success of realizing the successful energy production using fusion plasma, because a 3.5 MeV energetic alpha particle should be able to sustain the burning plasma ...

Current status and possible extension of the global neutron monitor network

Journal of Space Weather and Space Climate, 2020
The global neutron monitor network has been successfully used over several decades to study cosmic ray variations and fluxes of energetic solar particles. Nowadays, it is used also for space weather purposes, e.g. alerts and assessment of the exposure to
