As preparation for this Dahlem Workshop on The Dynamics of Fault Zones, specifically on the subtopic “Rheology of Fault Rocks and Their Surroundings,” we addressed critical research issues for understanding the seismic response of fault zones in terms of the constitutive response of fault materials. This requires new concepts and a host of new observations and experiments to document material r...

Presynaptic active zones contain a cytoskeletal matrix called the CAZ, which is thought to play a critical role in the regulation of active zone formation and neurotransmitter release. Recent studies have identified several CAZ components, but little is known about how they contribute to the molecular organization of active zones. Here, we report a novel PDZ [postsynaptic density-95/Discs large...

Localized strains due to production defects, seams, and punctured zones significantly affect mechanical performance of geosynthetic materials. Accurate determination of localized strains becomes particularly important for quality control/quality assurance evaluation of these materials and may play a critical role in design problems. A battery of tensile tests was conducted on 12 different geosy...

Recent research suggests that, due to misconfiguration, DNS reliability and performance is not always as good as it should be. This paper therefore investigates the correct configuration of DNS zones, by checking if main configuration requirements, recommendations and bestpractices rules have been followed. Our research shows that almost one out of four zones fail to pass one or more of our tes...

Several primate taxa show evidence of natural hybridization, and recent genomic analyses of modern and archaic humans have revealed the prevalence of hybridization during the evolutionary history of our own lineage. Thus interest in understanding how natural hybridization occurs in our closest relatives, the nonhuman primates, has grown rapidly. However, studies of the process and dynamics of h...

This paper investigates how the psychological notion of comfort can be useful in the design of robotic systems. A review of the existing study of human comfort, especially regarding its presence in infants, is conducted with the goal being to determine the relevant characteristics for mapping it onto the robotics domain. Focus is placed on the identification of the salient features in the envir...

With the aid of numerical experiments we examined the dynamical stability of fictitious terrestrial planets in 1:1 mean motion resonance with Jovian-like planets of extrasolar planetary systems. In our stability study of the so-called "Trojan" planets in the habitable zone, we used the restricted three-body problem with different mass ratios of the primary bodies. The application of the three-b...
