Artificial spike-based computation, inspired by models of computations in the central nervous system, may present significant performance advantages over traditional methods for specific types of large scale problems. In this paper, we study new models for two common instances of such computation, winner-take-all and coincidence detection. In both cases, very fast convergence is achieved indepe...

Monte Carlo simulation is used to obtain estimates of the probability that all weighted scoring rules elect the same winner for large electorates under the impartial culture condition. While this probability is relatively large for three candidate elections (0.535), it decreases significantly as the number of candidates increases. The same general observations are made when considering the prob...

This paper investigates the effect of relationship-lending on loan contract terms, especially on the interest rate, loan value, and collateral requirements. For this purpose, data on 4850 loans granted by a bank in 2016 is employed. Our estimations show a negative and significant relationship between the interest rate and quality and quantity of borrower-lender relationship. Furthermore, there ...

Let K denote a field and let V denote a vector space over K with finite positive dimension. We consider a pair of linear transformations A : V → V and A∗ : V → V that satisfy the following conditions: (i) each of A,A∗ is diagonalizable; (ii) there exists an ordering {Vi} d i=0 of the eigenspaces of A such that A ∗Vi ⊆ Vi−1+Vi+Vi+1 for 0 ≤ i ≤ d, where V−1 = 0 and Vd+1 = 0; (iii) there exists an...

Kleinrock, L. and F. Mehovi6, Poisson winner queues, Performance Evaluation 14 (1992) 79-101. We study special types of queues, winner queues, in which all customers are served concurrently. A customer in a winner queue will successfully finish his service (i.e. "win") and leave if no other customer leaves during his current service. Once a customer wins, all others in service at that time "los...
