Without monetary payments, the Gibbard-Satterthwaite theorem proves that under mild requirements all truthful social choice mechanisms must be dictatorships. When payments are allowed, the Vickrey-Clarke-Groves mechanism truthfully implements the value-maximizing choices, assuming agents’ utilities are quasi-linear in money. We study social choice with payments where utilities are non-quasi-lin...

In this article, we analyze the oscillation behavior of half-linear differential equation $$\big( r(t) t^{p-1} \Phi(x')\big)' + \frac{s(t)}{t \log^pt} \Phi(x) = 0, \quad \Phi(x)=|x|^{p-1}\text{sgn} x, p > 1. $$ Applying modified Prufer angle and a general averaging technique over unbounded intervals, prove an criterion for studied equation. We point out that presented is new even in linear c...

ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. we...

Network topology discovery is the basis for any network management application. The problem of estimating internal structure and link-level performance from end-to-end measurements is known as network tomography. This paper proposes a novel approach to discover network characteristics, in particular, tree topology from end-to-end path metrics between OD (Origin – Destination) pairs. The approac...

We present an application of Hilbert quasi-polynomials to order domain codes, allowing the effective computation of the order domain condition in a direct way. We also provide an improved and specialized algorithm for the computation of the related Hilbert quasi-polynomials.

Let D be an integral domain and X an indeterminate over D. It is well known that (a) D is quasi-Prüfer (i.e, its integral closure is a Prüfer domain) if and only if each upper to zero Q in D[X] contains a polynomial g ∈ D[X] with content cD(g) = D; (b) an upper to zero Q in D[X] is a maximal t-ideal if and only if Q contains a nonzero polynomial g ∈ D[X] with cD(g) v = D. Using these facts, the...

What is the role of expertise in evaluating creative products? Novices and experts do not assess creativity similarly, indicating domain-specific knowledge’s role in judging creativity. We describe two studies that examined how “quasi-experts” (people who have more experience in a domain than novices but also lack recognized standing as experts) compared with novices and experts in rating creat...
