Advanced Engineering Materials, EarlyView.Dislocation cutting of γ′ precipitates in Ni‐based superalloys is investigated by linking atomistic simulations with discrete dislocation dynamics. The critical cutting stress is shown to be governed by the antiphase boundary energy, while line tension effects promote edge‐preferred cutting.

Heavy tails and electricity prices: Do time series models with non-Gaussian noise forecast better than their Gaussian counterparts? [PDF]
This paper is a continuation of our earlier studies on short-term price forecasting of California electricity prices with time series models. Here we focus on whether models with heavy-tailed innovations perform better in terms of forecasting accuracy ...

Tail biting in pigs: is it possible to rear the heavy pig avoiding tail docking? [PDF]
, 2013 Tail biting in pigs has been identified as a behavioural problem for decades. It has serious consequences for animal welfare and for the income of the farmers The inability to prevent occurrence of this adverse behavior under commercial farm conditions ...

Advanced Engineering Materials, EarlyView.In situ synchrotron high‐energy X‐ray diffraction reveals the real‐time high‐temperature phase evolution of a ternary V‐9Si‐6.5B alloy. The study uncovers a kinetically delayed V5SiB2 → V8SiB4 transformation governed by massive structural and chemical barriers.

Heavy tails and electricity prices [PDF]
In the first years after the emergence of deregulated power markets it became apparent that for the valuation of electricity derivatives we cannot simply rely on models developed for financial or other commodity markets.

Indolo‐Fused MR‐TADF Materials and their Application in Organelle‐Targeted Bioimaging
Advanced Functional Materials, EarlyView.Using indolo‐fusion and sulfur bridging, four multi‐resonance thermally activated delayed fluorescent (MR‐TADF) materials are reported based on the quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) framework. Functionalization of these dyes with phosphonium groups enables cellular imaging with mitochondrial targeting in glassy organic nanoparticles ...

Robust Risk Management. Accounting for Nonstationarity and Heavy Tails [PDF]
In the ideal Black-Scholes world, financial time series are assumed 1) stationary (time homogeneous) and 2) having conditionally normal distribution given the past.

Variable Heavy Tails in Internet Traffic [PDF]
, 2008 This paper studies tails of the size distribution of Internet data flows and their “heaviness”. Data analysis motivates the concepts of moderate, far and extreme tails for understanding the richness of information available in the data. The data analysis

Geophysical Research LettersExtreme value theory is routinely applied to estimate rainfall frequency for several accumulation periods. Typically, it is found that sub‐daily precipitation has power‐type tails, meaning that the probability of observing increasingly large magnitudes ...

Precise Large Deviations for Subexponential Distributions in a Multi Risk Model
Risks, 2018 The precise large deviations asymptotics for the sums of independent identical random variables when the distribution of the summand belongs to the class S ∗ of heavy tailed distributions is studied.
