Abstract. Multivariate or compound hydrological-extreme events such as successive floods, large-scale droughts, consecutive drought-to-flood challenge water management and can be particularly impactful. Still, the multivariate nature of floods droughts is often ignored by studying individual characteristics only, which lead to under- overestimation risk. Studying extremes challenging because va...

The mechanism by which gauge and gravitational anomalies cancel in certain string theories is reviewed. The presentation is aimed at theorists who do not necessarily specialize in string theory. Talk presented at 2001: A Spacetime Odyssey – the inaugural conference of the Michigan Center for Theoretical Physics

After years of efforts to push the LEP performance to, and indeed beyond, the limits of what had been believed possible, hints of a signal of a Higgs boson at 115GeV/c appeared in June 2000, were confirmed in September, and confirmed again in November. Spending an additional six-month period with LEP would have given the unambiguous opportunity of a fundamental discovery. Instead, this possibil...

machines that can interact with them as they interact with each other. Science fiction writers have given us these goals in the form of HAL in 2001: A Space Odyssey and Commander Data in Star Trek: The Next Generation. However, at present, our computers are deaf, dumb, and blind, almost unaware of the environment they are in and of the user who interacts with them. In this article, I present th...

In Amazonia there remains the largest contiguous tropical forest of the planet. The vegetation, including its deep root system, is efficient in recycling water vapor, which is an important mechanism for the forests maintenance and helps to maintain evergreen canopies during dry seasons (Nepstad et al. 1994; Cox et al. 2008), demonstrating the adaptation of Amazon forest species to seasonal drou...
