Substituted naphthofurans and naphthopyrans were constructed at high temperature from allyl or propargyl naphthyl ethers via Claisen rearrangement in moderate to good yields. Also, substituted (trimethylsilyl)-naphthofurans were synthesized from the corresponding naphtofurans.

The prediction of a stock market direction may serve as an early recommendation system for short-term investors and as an early financial distress warning system for long-term shareholders. Many stock prediction studies focus on using macroeconomic indicators, such as CPI and GDP, to train the prediction model. However, daily data of the macroeconomic indicators are almost impossible to obtain....

The primary objective of the project was the development of criteria to define the end-of– life condition of pavements. These criteria could then be used in pavement performance modelling to obtain a more robust measure of remaining life. Another objective was the generation of a new model for maintenance costs. This could then be combined with the existing models for roughness and rutting to d...

Credit contagion refers to the propagation of economic distress from one firm to another. This article proposes a reduced-form model for these contagion phenomena, assuming they are due to the local interaction of firms in a business partner network. We study aggregate credit losses on large portfolios of financial positions contracted with firms subject to credit contagion. In particular, we p...

Although standard ethical views categorize intentional torture as morally wrong, the ticking time bomb (TTB) scenario is frequently offered as a legitimate counter-example that justifies the use of torture.
