Ring-LWE in Polynomial Rings [PDF]
, 2012 The Ring-LWE problem, introduced by Lyubashevsky, Peikert, and Regev (Eurocrypt 2010), has been steadily finding many uses in numerous cryptographic applications. Still, the Ring-LWE problem defined in [LPR10] involves the fractional ideal R ∨, the dual of the ring R , which is the source of many theoretical and implementation technicalities. Until now,

Response of Tree-Ring Density to Climate in Maine, U.S.A.
, 1979 Cores of red spruce (Picea rubens Sarg.) from three upper-elevation sites in Maine, U.S.A., were X-rayed, and minimum and maximum wood densities as well as ring widths were mechanically recorded.

Rings of rings: calixpyrrole cyclotrimers
Arkivoc, 2021 Los calixpirroles son una clase de heteromacrociclos que han sido un tema de considerable interés en las últimas dos décadas debido a su rica química huésped-huésped como receptores de aniones. Se han informado varias estructuras que comprenden más de una unidad de calixpirrol como receptores multitópicos y multivalentes.

Morita contexts and unitary ideals of rings [PDF]
Proceedings of the Estonian Academy of Sciences, 2021 In this paper we study Morita contexts between rings without identity. We prove that if two associative rings are connected by a Morita context with surjective mappings, then these rings have isomorphic quantales of unitary ideals.

Mathematical Model of Piston Ring Sealing in Combustion Engine
Polish Maritime Research, 2015 This paper presents a mathematical model of piston-rings-cylinder sealing (TPC) of a combustion engine. The developed model is an itegrated model of gas flow through gaps in TPC unit, displacements and twisting motions of piston rings in ring grooves as ...
