Regime Jumps in Electricity Prices [PDF]

open access: yes
Electricity prices are known to be very volatile and subject to frequent jumps due to system breakdown, demand shocks, and inelastic supply. As many international electricity markets are in some state of deregulation, more and more participants in these ...

On drift parameter estimation for mean-reversion type stochastic differential equations with discrete observations

open access: yes, 2016
We are concerned with a parameter estimation for mean-reversion type stochastic differential equations (SDEs) driven by Brownian motion. The equations, involving a small dispersion parameter, are observed at discrete (regularly spaced) time instants. The

Bio‐Inspired Magnetically Tunable Structural Colors from Elliptical Self‐Assembled Block Copolymer Microparticles

open access: yesAdvanced Functional Materials, EarlyView.
Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Two‐Way Shape Memory Alloy and Polymer Composite Hybrid Smart Actuator With High Speed, Accuracy, and Reversible Deformation

open access: yesAdvanced Functional Materials, EarlyView.
Tailored thermo‐mechanical properties of shape memory polymer composites enable large reversible deformation as well as high actuation speed. Moreover, a structural design with curvature in the transverse direction achieves sub‐second actuation on heating and a larger recovery ratio on cooling. Finally, these newly developed smart two‐way actuators can

Does survivorship bias really matter? An empirical investigation into its effects on the mean reversion of share returns on the JSE Securities Exchange (1984-2006) [PDF]

open access: yes
This paper tests for the impact of survivorship bias by building on the work of Cubbin, Eidne, Firer and Gilbert (2006), and Bailey and Gilbert (2007).

On openness and real exchange rate volatility [PDF]

open access: yes, 2008
We address the puzzle concerning the inverse relationship between openness and real exchange rate volatility. We argue that the relationship can be explained by increased openness facilitating purchasing power parity. Using New Zealand data, we show that

Novel Functional Materials via 3D Printing by Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Mean Reversion in the Nikkei, Standard & Poor and Dow Jones indices [PDF]

open access: yes, 2007
Three stock market indices (the Nikkei 225, the Standard and Poor’s 500 and the Dow Jones EURO STOXX 50) are analysed in this paper using a parametric procedure for fractional integration.
