Econometric Model Using Arbitrage Pricing Theory and Quantile Regression to Estimate the Risk Factors Driving Crude Oil Returns [PDF]
This work adopts a novel approach to determine the risk and return of crude oil stocks by employing Arbitrage Pricing Theory (APT) and Quantile Regression (QR).The APT identifies the underlying risk factors likely to impact crude oil returns.Subsequently, QR estimates the relationship between the factors and the returns across different quantiles of ...

Spray‐Assisted Fabrication of Cellulose Photonic Pigments on Superhydrophobic Surfaces
A method to directly produce structurally colored microparticles by drying cholesteric cellulose nanocrystal microdroplets on a superhydrophobic surface is reported. This approach has several key advantages that can unlock large‐scale fabrication of sustainable photonic pigments, including exploiting existing industrial techniques (e.g. aerosolization),

Regional Oil Extraction and Consumption: A simple production model for the next 35 years Part I [PDF]
The growing conflicts in and about oil exporting regions and speculations about volatile oil prices during the last decade have renewed the public interest in predictions for the near future oil production and consumption. Unfortunately, studies from only 10 years ago, which tried to forecast the oil production during the next 20-30 years, failed to ...

Chemically Reactive Thin Films: Dynamics and Stability
What happens to a thin liquid film when chemical reactions occur inside it? By means of theoretical analysis, it is showed that such systems (which are very common in heterogeneous catalysis) become very dynamic and not only their wetting properties are strongly affected by the chemical activity, moreover their interface can undergo traveling and ...
