From data fusion to knowledge fusion [PDF]
Proceedings of the VLDB Endowment, 2014 The task of data fusion is to identify the true values of data items ( e.g. , the true date of birth for Tom Cruise ) among multiple observed values drawn from different sources ( e.g. , Web sites) of varying (and unknown) reliability.

Status of the ITER ECRH&CD control system development [PDF]
EPJ Web of Conferences, 2023 The ITER ECRH&CD system is designed to inject 20 MW of millimetre-wave at 170 GHz into the vacuum vessel. The system is composed of many sub-systems, namely High-Voltage Power Supplies (HVPS), Gyrotrons, Transmission Lines (TL), Ex-vessel Waveguides (EW),

Differentiating multi-MeV, multi-ion spectra with CR-39 solid-state nuclear track detectors
Scientific Reports, 2023 The development of high intensity petawatt lasers has created new possibilities for ion acceleration and nuclear fusion using solid targets. In such laser-matter interaction, multiple ion species are accelerated with broad spectra up to hundreds of MeV ...

Preceding propagation of turbulence pulses at avalanche events in a magnetically confined plasma
Scientific Reports, 2022 The preceding propagation of turbulence pulses has been observed for the first time in heat avalanche events during the collapse of the electron internal transport barrier (e-ITB) in the Large Helical Device.

Fiber 2-Functors and Tambara-Yamagami Fusion 2-Categories [PDF]
Communications in Mathematical Physics 406, 64 (2025), 2023 We introduce group-theoretical fusion 2-categories, a strong categorification of the notion of a group-theoretical fusion 1-category. Physically speaking, such fusion 2-categories arise by gauging subgroups of a global symmetry. We show that group-theoretical fusion 2-categories are completely characterized by the property that the braided fusion 1 ...

Experimental determination of the cooling efficiency of a high-temperature surface by a pneumatic nozzle [PDF]
E3S Web of Conferences, 2023 The cooling of surfaces that perceive high heat fluxes (more than 7 MW/m2) at the current pace of development of the energy sector will become one of the main problems of the near future. In this paper, as one of the options for effective cooling of high-

Cell, 2003 Membrane fusion, one of the most fundamental processes in life, occurs when two separate lipid membranes merge into a single continuous bilayer. Fusion reactions share common features, but are catalyzed by diverse proteins. These proteins mediate the initial recognition of the membranes that are destined for fusion and pull the membranes close together

Entropy, 2023 What are conscious experiences? Can they combine to form new experiences? What are conscious subjects? Can they combine to form new subjects? Most attempts to answer these questions assume that spacetime, and some of its particles, are fundamental. However, physicists tell us that spacetime cannot be fundamental. Spacetime, they say, is doomed. We heed

Comparison between measurement and calculations for a 14 MeV neutron water activation experiment [PDF]
EPJ Web of Conferences, 2020 The nuclear heat loads due to gamma rays emitted from the decay of 16N and delayed neutrons from17N, generated by the activation of water in cooling circuits, are critical for ITER design. The assessment of nuclear heating from activated water is complex;

Long-pulse Plasma Discharges by Upgraded ECH System in the LHD
EPJ Web of Conferences, 2015 Until 2009, three high-power, over 1MW each, 77GHz gyrotrons have been installed and applied to the LHD experiment. In addition, a 154GHz gyrotron of 1MW was installed in 2012. The 77GHz gyrotrons suffer gradual increases of internal pressure during long-
