Nonperturbative Ambiguities and the Reality of Resurgent Transseries

, 2014
In a wide range of quantum theoretical settings -- from quantum mechanics to quantum field theory, from gauge theory to string theory -- singularities in the complex Borel plane, usually associated to instantons or renormalons, render perturbation theory

Exchange Rates and Product Variety [PDF]

We study the role of exchange rate variability in the firm's choice of whether to o¤er one or two varieties. We show that variability induces the firm to vertically segment markets (offer two varieties).

Winners and losers in transition : returns to education, experience, and gender in Slovenia [PDF]

The authors identify winners and losers in Slovenia's economic transition by tracing changes in returns to education, experience, and gender and changes in wage inequality from 1987 to 1991. They find the following. Relative wages and employment rose for

Development of a Compact Incremental Forming Machine

Machines
Since the beginning of the 21st century, incremental sheet-metal-forming processes, such as single-point incremental forming (SPIF), have been the subject of extensive research.
