1. Explainable AI: A Neurally-Inspired Decision Stack Framework

Abstract

European Law now requires AI to be explainable in the context of adverse decisions affecting European Union (EU) citizens. At the same time, it is expected that there will be increasing instances of AI failure as it operates on imperfect data. This paper puts forward a neurally-inspired framework called decision stacks that can provide for a way forward in research aimed at developing explainable AI. Leveraging findings from memory systems in biological brains, the decision stack framework operationalizes the definition of explainability and then proposes a test that can potentially reveal how a given AI decision came to its conclusion.

22. Fabrication of Small Magnets Using Mono- and Seven-Core (Ba,A)Fe2As2 (A: K, Na) HIP Round Wires

Author

Tamegai, T., Pyon, S., Ito, T., Kajitani, H., Koizumi, N., Awaji, S., Kito, H., Ishida, S., and Yoshida, Y.

Abstract

Small magnets using 18-m class mono-core (Ba,Na)Fe2As2 and seven-core (Ba,K)Fe2As2 round wires were constructed. Wires used in these magnets were fabricated using powder-in-tube method followed by hot isostatic pressing process. Both magnets show zero resistivity at low currents, and strong increase in resistance shows up at 47-53 A. Generated magnetic fields at these currents were 3.1 kOe and 2.7 kOe for magnets using mono-core (Ba,Na)Fe2As2 and seven-core (Ba,K)Fe2As2 round wires, respectively. Short pieces of the long wires used for the magnets were evaluated independently after disassembling the magnets. It turns out that critical current (Ic) varies significantly along the length of the wire, and the largest Ic reaches 160 A in mono-core (Ba,Na)Fe2As2 wire. X-ray tomography observations of the wires revealed severe sausaging effect even in a few mm length scale, which could be the reason for the large variation of Ic along the entire length of the wire. We also evaluated the effect of bending strain on mono-core and multi-core (Ba,Na)Fe2As2 wires. Effects of bending strain turns out to be modest, and more than 60% of Ic was sustained even at the bending strain of 0.5%.

Abstract

Einleitung: Die Rho-assoziierte Kinase (ROCK) ist ein Enzym, welches verschiedene Vorgänge in Zellen steuert. Die Inhibition von ROCK stimuliert möglicherweise die Wanderung von Endothelzellen im Kontext der Fuchs’schen Endotheldystrophie und senkt den Augeninnendruck beim Offenwinkelglaukom.[zum vollständigen Text gelangen Sie über die oben angegebene URL], Jahrestagung 2019 der Sächsischen Augenärztlichen Gesellschaft
