Publikováno v: 2019 IEEE International Electron Devices Meeting (IEDM).

We demonstrate an analog neuro-optimization hardware, suitable for solving a large number of combinatorial optimization problems, based on a crossbar circuit with 4096 passively-integrated analog-grade memristors. The proposed hardware supports a var

Positronium in a cavity in a high-Tcsuperconductor

Autor: Viktor L Sedov

Publikováno v: Physics-Uspekhi. 52:687-694

The behavior of positronium localized in a microvoid in a high-temperature superconductor (HTSC) environment is examined. The interaction of such a positronium with conduction electrons is treated as arising from the Ps ? e+ + e? process, which is ma

Influence of the structures of α-halo ketones and thioamides on the Hantzsch synthesis of thiazoles and thiazolo[5,4-b]indoles. A new approach to 4-acetyl-2-methyl-4H-thiazolo[5,4-b]indole

In reactions with some α-halo ketones (3-bromo-1,1,1-trifluoropropan-2-one, 1-acetyl-2-bromoindolin-3-one, and α-bromoacetophenone), thioacetamide and a series of thioamides of aromatic and heteroaromatic acids are transformed into 4-hydroxy-Δ2-th

Publikováno v: Chemistry of Heterocyclic Compounds. 41:526-535

By reaction of 4-substituted 5-amino-6-mercaptopyrimidines with 5-bromo-2,2-dimethyl-4,6-dioxo-1,3-dioxane, we have obtained 4′-substituted 5-(5-amino-6-pyrimidylthio)-2,2-dimethyl-4,6-dioxo-1,3-dioxanes. We have studied diazotization of these comp
