A means to sharper images

Autobiographical Brand Images Give a Higher Chance to False Memory as Compared to Neutral Images

Consumers’ prior experiences shape an episodic memory which largely influences their decision-making process. This episodic memory is mainly linked to cognitive and emotional perception and we know that a brand image influences our cognitive and emotional perception. Nevertheless, it has not been well described how autobiographical memories of brand images differ from those of other types of im...

Using SharpeR

The SharpeR package provides basic functionality for testing significance of the Sharpe ratio of a series of returns, and of the Markowitz portfolio on a number of possibly correlated assets.[15] The goal of the package is to make it simple to estimate profitability (in terms of riskadjusted returns) of strategies or asset streams. 1 The Sharpe ratio and Optimal Sharpe ratio Sharpe defined the ...

Sharper Ring-LWE Signatures

We present TESLA] (pronounced “Tesla Sharp”), a digital signature scheme based on the R-LWE assumption that continues a recent line of proposals of lattice-based digital signature schemes originating in work by Lyubashevsky as well as by Bai and Galbraith. It improves upon all of its predecessors in that it attains much faster key pair generation, signing, and verification, outperforming most (...

A circuit uniformity sharper than DLogTime

We consider a new notion of circuit uniformity based on the concept of rational relations, called Rational-uniformity and denoted Rat. Our goal is to prove it is sharper than DLogTime-uniformity, the notion introduced by Barrington et al. [3], denoted DLT , that is: 1) Rational-uniformity implies DLogTime-uniformity, 2) we have NCRat NCDLT ( NCRat, 3) we have ∀k > 0, NCDLT ⊆ NC Rat , 4) Rationa...
