Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Species traits shape the relationship between local and regional species abundance distributions

open access: yesEcosphere, 2019
The species abundance distribution (SAD) depicts the relative abundance of species within a community, which is a key concept in ecology. Here, we test whether SADs are more likely to either follow a lognormal‐like or follow a logseries‐like distribution

Threshold Asymmetric Conditional Autoregressive Range (TACARR) Model

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT This paper introduces a Threshold Asymmetric Conditional Autoregressive Range (TACARR) model for analyzing the daily price ranges of financial assets. The proposed formulation assumes that the conditional expected range switches between two regimes, representing upward and downward market states, with the disturbance distribution also allowed ...
