Current biomedical research increasingly requires imaging large and thick 3D structures at high resolution. Prominent examples are the tracking of fine filaments over long distances in brain slices, or the localization of gene expression or cell migration ...
We define quittable consensus, a natural variation of the consensus problem, where processes have the option to agree on "quit" if failures occur, and we relate this problem to the well-known problem of nonblocking atomic commit. We then determine the weak ...

This paper investigates variance risk premia in energy commodities, particularly crude oil and natural gas, using a robust model-independent approach. Over a period of 11 years, we find that the average variance risk premia are significantly negative for b ...
The 1987 market crash was associated with a dramatic and permanent steepening of the implied volatility curve for equity index options, despite minimal changes in aggregate consumption. We explain these events within a general equilibrium framework in whic ...
We integrate a probabilistic demand model in the train timetabling problem. We use a logit model that we calibrate to reflect the known demand elasticities. We further include a competing operator as an opt-out option for the passengers. Subsequently, we i ...
We develop an econometric method to detect "abnormal trades" in option markets, i.e., trades which are not driven by liquidity motives. Abnormal trades are characterized by unusually large increments in open interest, trading volume, and option returns, an ...
With the occurrence of higher and more frequent axle loads, bridges are more solicited by fatigue loading. Bridge elements like deck slabs are subjected to a high number of stress cycles at relatively small stress magnitudes. The application of Fracture Me ...
Understanding the investment decisions of power companies is vital for a regulator as particularly deficient investments in generation capacity could jeopardize the market in the long run. Considering potential risks that could hamper investments, the pape ...
This paper examines the effects of capital gains taxation on firms’ investment and financing decisions. We develop a real options model in which the timing of investment, the decision to default, and the firm’s capital structure are endogenously and jointl ...
We propose a parsimonious 'unspanned stochastic volatility' model of the term structure and study its implications for fixed-income option prices. The drift and quadratic variation of the short rate are affine in three state variables (the short rate, its ...
