Generalised Kinematic Single‐Impact and Multi‐Impact Models for Rocking Structures

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The rocking motion is fundamental in earthquake engineering, as it reflects the dynamic behaviour of many structural systems. However, simulating the impacts during rocking motion remains a challenging topic, as they occur in a very short time, generate high impulsive forces, cause sudden changes in velocities and result in rapid energy losses.

Theoretical Model of Transient Regression of Thermoplastic Materials During Flame Spread: Vaporization; Permanent Mass Loss; Surface Shape

Fire and Materials, EarlyView.
ABSTRACT This article examines a transient, one‐dimensional model of surface regression during opposed flow flame spread over finite thickness, non‐charring thermoplastics. Gas to solid conductive transfer from the flame drives sample heating. The solid degrades into volatile fuel molecules in two stages: (1) the pre‐vaporization heat‐up stage and (2 ...

A Comparison of Realized Measures of Integrated Volatility: Price Duration‐ vs. Return‐Based Approaches

Journal of Forecasting, EarlyView.
ABSTRACT We study the accuracy of a variety of parametric price duration‐based realized variance estimators constructed via various financial duration models and compare their forecasting performance with the performance of various nonparametric return‐based realized variance estimators.

Coherent Forecasting of Realized Volatility

Journal of Forecasting, EarlyView.
ABSTRACT The QLIKE loss function is the stylized favorite of the literature on volatility forecasting when it comes to out‐of‐sample evaluation and the state of the art model for realized volatility (RV) forecasting is the HAR model, which minimizes the squared error loss for in‐sample estimation of the parameters.

Projected Warming of the Southern Ocean Disrupts Embryonic Development and Hatch Timing in Antarctic Fish

Global Change Biology Communications, EarlyView.
Embryos are particularly sensitive to thermal challenge. Antarctic fish embryos raised at projected Southern Ocean temperatures hatch during the winter, have a high incidence of morphological abnormalities, have shorter body lengths, and express genes indicative of cellular stress.
