Are realized volatility models good candidates for alternative Value at Risk prediction strategies?

open access: yes
In this paper, we assess the Value at Risk (VaR) prediction accuracy and efficiency of six ARCH-type models, six realized volatility models and two GARCH models augmented with realized volatility regressors.

Bubble Formation Control: Fabrication of Centimeter‐Sized Tissue‐Like Constructs by Catalase‐Coated Oxygen‐Releasing Hydrogel

open access: yesAdvanced Materials, EarlyView.
Oxygen‐releasing hydrogels are widely used to support cell survival in 3D cultures and to promote wound healing. However, incorporating catalase to convert H2O2 into O2 often generates additional oxygen bubbles, leading to material instability which rarely addressed.

Crisis, Value at Risk, and Conditional Extreme Value Theory via Garch-Jump Model

open access: yes, 2010
This study develops a new conditional extreme value theory-based model (EVT) combined with the GARCH-Jump model to forecast extreme risks. This paper utilizes the GARCH-Jump model to asymmetrically feed back the past realization of jump innovation to the
