‎In this note‎, ‎we consider the concentration function problem for a continuous action of a locally compact group $G$ on a locally compact Hausdorff space $X$‎. ‎We prove a necessary and sufficient condition for the concentration functions of a‎ ‎spread-out irreducible probability measure $mu$ on $G$ to converge to zero.

background: citizenship education is increasingly considered as an important strategy to empower youths in taking responsibilities and playing their individual and social roles, and to protect them against psychosocial pathologies. the purpose of the present descriptive study was to investigate students’ levels of knowledge,  their intention, subjective norms, and attitudes toward the character...

oxidative stress has been implicated in the progression of hiv to aids, since hiv usually replicates in a highly oxidized condition and cd4+ t lymphocytes can be activated via a cascade of internal oxidative pathways, which enhances the formation of proteins and enzymes. thus, antioxidants should potentially be useful for the treatment and prevention of hiv infection as a new alternative strate...

We study a leader election protocol that we call the Swedish leader election protocol. This name comes from a protocol presented by L. Bondesson, T. Nilsson, and G. Wikstrand (2007). The goal is to select one among n > 0 players, by proceeding through a number of rounds. If there is only one player remaining, the protocol stops and the player is declared the leader. Otherwise, all remaining pla...

The model of population protocols refers to a large collection of simple indistinguishable entities, frequently called agents. The agents communicate and perform computation through pairwise interactions. We study fast and space efficient leader election in population of cardinality $n$ governed by a random scheduler, where during each time step the scheduler uniformly at random selects for int...

the study of design and formation of urban space focuses on interaction of human and environment. this is an attractive subject that considers as interdisciplinary debates. thinkers of urban studies pay attention to this matter empirically and theoretically in order to provide a desirable space for human being. this research is based on the theories of urban studies and urban sociology and so o...

Using a generalized spherical mean operator, we obtain a generalization of Titchmarsh's theorem for the Dunkl transform for functions satisfying the ('; p)-Dunkl Lipschitz condition in the space Lp(Rd;wl(x)dx), 1 < p 6 2, where wl is a weight function invariant under the action of an associated re ection group.

We consider the problem of electing a leader on a ring of nameless processors by de terministic and self stabilizing protocols A processor can read the state of its neighbors and its own state to determine if it is enabled A central demon scheduler picks an enabled processor to make an atomic move In an atomic move the processor changes to a new state which is a function of its old state and th...
