Recently, in [11], the “coin-turning walk” was introduced on Z. It is a non-Markovian process where steps form (possibly) time-inhomogeneous Markov chain. In this article, we follow up investigation by introducing analogous processes Zd,d≥2: at time n direction of “updated” with probability pn; otherwise next step repeats previous one. We study some fundamental properties these walks, such as t...

We study a novel multi-armed bandit problem that models the challenge faced by a company wishing to explore new strategies to maximize revenue whilst simultaneously maintaining their revenue above a fixed baseline, uniformly over time. While previous work addressed the problem under the weaker requirement of maintaining the revenue constraint only at a given fixed time in the future, the algori...

In this paper we study the nonchaotic and chaotic behavior of all 3D conservative quadratic ODE systems with five terms on the right-hand side and one nonlinear term (5-1 systems). We prove a theorem which provides sufficient conditions for solutions in 3D autonomous systems being nonchaotic. We show that all but five of these systems:(3.8a,b), (3.11b), (3.34)(A = ∓1), (4.1b),and (4.7a,b) are n...

Comirit is a framework for commonsense reasoning that combines simulation, logical deduction and passive machine learning. While a passive, observation-driven approach to learning is safe and highly conservative, it is limited to interaction only with those objects that it has previously observed. In this paper we describe a preliminary exploration of methods for extending Comirit to allow safe...

A polarization has developed in American political debates concerning the nature of society as a rational agent that implements policies to govern individual behavior. As analyzed by Lakoff, the reasons for discord are not entirely based on logical consistency, but originate in radically different moral principles based on metaphors, values, and faith. How people attend to alternative views, ha...

Do mundane daily choices, such as what brands people buy in a supermarket, reflect aspects of values and ideologies? This article presents a large-scale field study performed to determine whether traits associated with a conservative ideology, as measured by voting behavior and religiosity, are manifested in consumers' routine, seemingly inconsequential product choices. Our analysis of market s...

Objective: After considering great inter-individual variability of subjective experience and clinical course in reference to conservative non-conservative gynecological surgical interventions, an attempt was made evaluate potential role several psychological variables with respect perioperative symptomatology illness behaviour. Materials methods: The sample consists 58 women (mean age 41.4 ± 8....

In this paper, we present an unsplit method for the time-dependent compressible Navier-Stokes equations in two and three dimensions. We use a a conservative, second-order Godunov algorithm. We use a Cartesian grid, embedded boundary method to resolve complex boundaries. We solve for viscous and conductive terms with a second-order semiimplicit algorithm. We demonstrate second-order accuracy in ...

In this paper I simulate neighborhood level political migration dynamics following a change in neighborhood racial composition using SimPolSeg, an original agent-based modeling software program. SimPolSeg simulates agent behavior according to the Migration-Polarization (MP) theory of partisan sorting (Anastasopoulos 2014a). Dynamic simulations using SimPolSeg demonstrate how non-white migration...

The system of linearly coupled nonlinear Schrödinger equations is solved by a conservative difference scheme in complex arithmetic. The initial condition represents a superposition of two one-soliton solutions of linear polarizations. The head-on and takeover interaction of the solitons and their quasi-particle (QP) behavior is examined in conditions of rotational polarization and gain. We foun...
