Atmospheric observations of the water vapour continuum in the near-infrared windows between 2500 and 6600 cm-1 [PDF]

open access: yes, 2020
Water vapour continuum absorption is potentially important for both closure of the Earth's energy budget and remote sensing applications. Currently, there are significant uncertainties in its characteristics in the near-infrared atmospheric windows at 2 ...

Value at Risk models with long memory features and their economic performance [PDF]

open access: yes, 2015
We study alternative dynamics for Value at Risk (VaR) that incorporate a slow moving component and information on recent aggregate returns in established quantile (auto) regression models. These models are compared on their economic performance, and also

GFC-Robust Risk Management Under the Basel Accord Using Extreme Value Methodologies [PDF]

open access: yes, 2013
In McAleer et al. (2010b), a robust risk management strategy to the Global Financial Crisis (GFC) was proposed under the Basel II Accord by selecting a Value-at-Risk (VaR) forecast that combines the forecasts of different VaR models.

Search Tracker: Human-derived object tracking in-the-wild through large-scale search and retrieval [PDF]

open access: yes, 2016
Humans use context and scene knowledge to easily localize moving objects in conditions of complex illumination changes, scene clutter and occlusions. In this paper, we present a method to leverage human knowledge in the form of annotated video libraries ...

Forecasting Value-at-Risk Using Nonlinear Regression Quantiles and the Intraday Range [PDF]

open access: yes
Value-at-Risk (VaR) is commonly used for financial risk measurement. It has recently become even more important, especially during the 2008-09 global financial crisis.

A more‐than‐human political ecology of Indonesian songbird trade

open access: yesConservation Biology, EarlyView.
Abstract Since its inception, conservation science has considered wildlife trade a problem. In focusing on conservation outcomes, conservationists almost completely ignore the welfare of traded animals and plants and the harms they endure. We developed a political ecology approach that incorporates the interconnectedness of people with animals and ...

Detect the unexpected: a science for surveillance [PDF]

open access: yes, 2008
Purpose – The purpose of this paper is to outline a strategy for research development focused on addressing the neglected role of visual perception in real life tasks such as policing surveillance and command and control settings. Approach – The scale of

Axial muscle‐fibre orientations in larval zebrafish

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 517-533, April 2025.
In 4 days post‐fertilization zebrafish larvae, the fast axial muscle fibres follow helical trajectories that taper towards the tail. Adjacent muscle fibres form substantial angles relative to each other to accommodate this pattern. Using a novel semi‐automatic method, we quantified 3D fibre angles over the whole muscle volume.
