Heavy rainfall induced colony fission and nest relocation in nocturnal bull ants (Myrmecia midas)
BiologiaIn recent years the bull ant Myrmecia midas Clark, 1951, has attracted attention for its impressive visual navigation during its nocturnal activity. Still, a basic understanding of this species’ ecology is lacking. Nest relocation and colony fissions are

Advanced Science, EarlyView.Magnesium silicide (Mg2Si) is introduced as a narrow‐bandgap, biodegradable semiconductor for transient electronics. RF‐sputtered and annealed Mg2Si thin films show high intrinsic electrical conductivity and low thermal conductivity. The polycrystalline material undergoes hydrolysis in aquatic and composting environments with minimal cytotoxicity ...

Markov-Switching MIDAS Models [PDF]
Journal of Business & Economic Statistics, 2013 This article introduces a new regression model—Markov-switching mixed data sampling (MS-MIDAS)—that incorporates regime changes in the parameters of the mixed data sampling (MIDAS) models and allows for the use of mixed-frequency data in Markov-switching models.

A Fuzzy Framework for Realized Volatility Prediction: Empirical Evidence From Equity Markets
Journal of Forecasting, EarlyView.ABSTRACT This study introduces a realized volatility fuzzy time series (RV‐FTS) model that applies a fuzzy c‐means clustering algorithm to estimate time‐varying c$$ c $$ latent volatility states and their corresponding membership degrees. These memberships are used to construct a fuzzified volatility estimate as a weighted average of cluster centroids.
