A virtual test facility (VTF) for studying the three-dimensional dynamic response of solid materials subject to strong shock and detonation waves has been constructed as part of the research program of the Center for Simulating the Dynamic Response of Materials at the California Institute of Technology. The compressible fluid flow is simulated with a Cartesian finite volume method and treating the solid as an embedded moving body, while a Lagrangian finite element scheme is employed to describe the structural response to the hydrodynamic pressure loading. A temporal splitting method is applied to update the position and velocity of the boundary between time steps. The boundary is represented implicitly in the fluid solver with a level set function that is constructed on-the-fly from the unstructured solid surface mesh. Block-structured mesh adaptation with time step refinement in the fluid allows for the efficient consideration of disparate fluid and solid time scales. We detail the design of the employed object-oriented mesh refinement framework AMROC and outline its effective extension for fluid-structure interaction problems. Further, we describe the parallelization of the most important algorithmic components for distributed memory machines and discuss the applied partitioning strategies. As computational examples for typical VTF applications, we present the dynamic deformation of a tantalum cylinder due to the detonation of an interior solid explosive and the impact of an explosion-induced shock wave on a multi-material soft tissue body.

Intracellular invasion of Staphyloccocus aureus in nonphagocytic cells Staphylococcus aureus often causes chronic diseases. It is now believed that recurrence of these infections could be related to the ability of S. aureus to invade and persist within nonphagocytic cells. Adherence to eucaryotic cells is crucial for S. aureus to invade and persist within invasion and depends on interactions between bacterial fibronectin-binding proteins, fibronectin and the host cell fibronectin receptor, integrin alpha(5)beta(1). It is currently established that fibronectin acts as a bridging molecule. Penetration of S. aureus in host cells requires also activation of protein tyrosine kinases that mediate signal transduction and actin polymerization leading to cytoskeletal rearrangements. After internalization, S. aureus either remains in membrane-bound vacuoles or appears free in the cytoplasm. After bacterial proliferation, S. aureus induces host cell apoptosis or persist inside cells as small colony variants, which represent a less virulent subpopulation of S. aureus that grows slower. Although numerous in vitro and in vivo studies have demonstrated the ability of S. aureus to invade nonphagocytic cells, additional experiments have to be realized to understand the relevance of intracellular localization in vivo.

We present an extension to the Data INterpolating Empirical Orthogonal Functions (DINEOF) technique which allows not only to fill in clouded images but also to provide an estimation of the error covariance of the reconstruction. This additional information is obtained by an analogy with optimal interpolation. It is shown that the error fields can be obtained with a clever rearrangement of calculations at a cost comparable to that of the interpolation itself. The method is presented on the reconstruction of sea-surface temperature in the Ligurian Sea and around the Corsican Island (Mediterranean Sea), including the calculation of inter-annual variability of average surface values and their expected errors. The application shows that the error fields are not only able to reflect the data-coverage structure but also the covariances of the physical fields. [less ▲]

We have investigated the hypothesis that pyrimidine dinucleotides are avoided in light-exposed genomes as the result of selective pressure due to high ultraviolet (UV) exposure. The main damage to DNA produced by UV radiation is known to be the formation of pyrimidine photoproducts: it is estimated that about 10 dimers per minute are formed in an Escherichia coli chromosome exposed to the UV light in direct overhead sunlight at sea level. It is also known that on an E. coli chromosome exposed to UVb wavelengths (290-320 nm), pyrimidine photoproducts are formed in the following proportions: 59 TpT, 7 CpC, and 34 CpT plus TpC. We have analyzed all available complete prokaryotic genomes and the model organism Prochlorococcus marinus and have found that pyrimidine dinucleotides are not systematically avoided. This suggests that prokaryotes must have sufficiently effective protection and repair systems for UV exposure to not affect their dinucleotide composition. [less ▲]

Nanoindentation is a versatile tool to probe local plastic properties of materials. Finite element (FE) modelling is currently used to identify material data from nanoindentation tests [1-4]. The general ambition of this research is to extract the material parameters describing the response of a new Ti alloy, called Ti-555, in order to perform simulations on representative microscopic cells and guide the optimisation of this alloy. In this paper, the first steps of the identification of the macroscopic flow parameters of the β-phase are described. The nanoindentation tests using a pyramidal Berkovich diamond indenter are performed in the β-phase. The FEM results with different parameters of an isotropic and anisotropic elasto-plastic (EP) constitutive law are analyzed and the predicted shapes are compared to the final shape of the indented material. The FE results very much depend on physical model choices, and cannot rely on an automatic identification approach. [less ▲]
