The Quarterly Journal of Economics, 2004 We estimate the effect of international trade on average laborproductivity at the country level. Our empirical approach relies onsummary measures of trade that, we argue, are preferable on boththeoretical and empirical grounds to the one conventionally used.

Advanced Engineering Materials, EarlyView.The study presents an efficient simulation approach for the polymer laser powder bed fusion process polymers process, validated with polyamide 12, polyamide 6, and polyetherketoneketone. It shows that inter layer time affects part density, with 90s yielding dense parts.

METHOD OF FOREST FIRES PROBABILITY ASSESSMENT WITH POISSON LAW
InterCarto. InterGIS, 2016 The article describes the method for the forest fire burn probability estimation on a base of Poisson distribution. The λ parameter is assumed to be a mean daily number of fires detected for each Forest Fire Danger Index class within specific period of ...

Symmetrization of the Berezin Star Product and Multiple Star Product Method [PDF]
, 2000 We construct a multiple star product method and by using this method, show that integral forms of some star products can be written in terms of the path-integral. This method can be applied to some examples. Especially, the associativity of the skew-symmetrized Berezin star product proposed in \cite{SW}, is recovered in large $N$ limit of the multiple ...

Generalized quasi-shuffle products [PDF]
arXiv, 2023 In this paper, we introduce the notion of generalized quasi-shuffle products and give a criterion for their associativity. These extend the quasi-shuffle products introduced by Hoffman, which are often used to describe the stuffle and shuffle product for multiple zeta values. For $q$-analogues of multiple zeta values, the description of an analogue for

Assessing the Ecological Value: Monetizing Process Innovations in Tailored Forming
Advanced Engineering Materials, EarlyView.This article introduces a method for evaluating the sustainability of innovations, even with limited data. The method is illustrated through an analysis of the “Tailored Forming” technology, which explores the impact of sustainability on economic value added.

A tensor product of representations of UHF algebras arising from Kronecker products [PDF]
arXiv, 2009 We introduce a non-symmetric tensor product of representations of UHF algebras by using Kronecker products of matrices. We prove tensor product formulae of GNS representations by product states and show examples.
