Global parametric sensitivity analysis of a complete seismic risk scenario is performed by means of the response surface method based on sparse Chebyshev polynomial expansion. Hazard model, described via a mixed technique combining Green’s function and stochastic methods, is used to simulate free-field seismic records. Vulnerability model, based on the period-dependent damage spectra, i…

Behavioral studies performed in natural habitats provide a context for the development of hypotheses and the design of experiments relevant both to biomechanics and to evolution. In particular, predator–prey interactions are a model system for integrative study because success or failure of predation has a direct effect on fitness and drives the evolution of specialized performance in both p…

Maximal whole-organism performance traits measured in the laboratory and the levels of performance expressed in the field often exhibit a mismatch, complicating our understanding of the selection pressures influencing the evolution of performance traits. To better understand the evolution of locomotor performance, we built an individualbased simulation to test hypotheses about selection on loco…

The Indochina block is important to our understanding of the extrusion model as a consequence of the Indo-Eurasia collision. The lithospheric structure of this block, however, remains obscured due to a lack of sufficient instrumentation for high resolution seismic imaging. We present as hear velocity model derived from Ray leigh wave phase velocity tomography using data from recently depl…

How fast should animals move when trying to survive? Although many studies have examined how fast animals can move, the fastest speed is not always best. For example, an individual escaping from a predator must run fast enough to escape, but not so fast that it slips and falls. To explore this idea, we developed a simple mathematical model that predicts the optimal speed for an individual runni…
