Unit Root Properties of Crude Oil Spot and Futures Prices [PDF]
In this paper we examine whether WTI and Brent crude oil spot and futures prices (at one, three and six months to maturity) contain a unit root with one and two structural breaks, employing weekly data over the period 1991-2004. To realize this objective

Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Non-renewable Resource Prices: Structural Breaks and Long Term Trends [PDF]
In this paper we examine the time series properties of nine non-renewable resources. In particular we are concerned with understanding the relationship between the number of structural breaks in the data and the nature of the resource price path, i.e. is

Breaking the panels. An application to the GDP per capita [PDF]
This paper proposes a test statistic for the null hypothesis of panel stationarity that allows for the presence of multiple structural breaks. Two different specications are considered depending on the structural breaks affecting the individual effects ...

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Multiple Structural Breaks in Australia's Macroeconomic Data: An Application of the Lumsdaine and Papell Test [PDF]
This paper employs all available annual time series data to endogenously determine the timing of structural breaks for 10 macroeconomic variables in the Australian economy. The ADF (Augmented Dickey and Fuller) test and the LP (Lumsdaine and Papell, 1997)
