On usefulness, uselessness, attractiveness and harm

On the uselessness of quantum queries

Given a prior probability distribution over a set of possible oracle functions, we define a number of queries to be useless for determining some property of the function if the probability that the function has the property is unchanged after the oracle responds to the queries. A familiar example is the parity of a uniformly random Boolean-valued function over {1, 2, . . . , N}, for which N − 1...

The Uselessness of Public Use

Effect of Positive and Negative Embodies on Attractiveness Processes

Background and Objective: Human being as a social-emotional being is constantly adapting to the environment. In this regard, interpersonal excitement is very important in terms of interpersonal communication as well as in terms of social perception. Therefore, the purpose of this study was to investigate the effect of positive and negative excitement induced on attention processes. Method...

on semihypergroups and hypergroups

in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...

compactifications and function spaces on weighted semigruops

chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
