Using large-scale numerical simulations, we analyze the statistical properties of fracture in the two-dimensional random spring model and compare it with its scalar counterpart: the random fuse model. We first consider the process of crack localization measuring the evolution of damage as the external load is raised. We find that, as in the fuse model, damage is initially uniform and localizes ...

In this paper, we describe the implementation and evaluation of the distributed secure file system based on FUSE. A tremendous amount of content is now saved on file servers. File servers and network storage can also easily be installed in small organizations by using operating systems such as Linux. However, the storage capacity of PCs that are generally used is also increasing due to low-pric...

Estimating and tracking the state is a fundamental ability of any autonomous system. The complexity of state spaces in typical applications frequently necessitate approximate filtering techniques such as particle filters. However, these methods often suffer from the curse of dimensionality when attempting to maintain a high-dimensional joint posterior distribution. Based on the insight that mos...

Clearly, the fossil record from the Cambrian period is an invaluable tool for deciphering animal evolution. Less clear, however, is how to integrate the paleontological information with molecular phylogeny and developmental biology data. Equally challenging is answering why the Cambrian period provided such a rich interval for the redeployment of genes that led to more complex body plans.

A fiber fuse phenomenon in polymer optical fibers (POFs) has recently been observed, and its unique properties such as slow propagation, low threshold power density, and the formation of a black oscillatory damage curve, have been reported. However, its characterization is still insufficient to well understand the mechanism and to avoid the destruction of POFs. Here, we present detailed experim...

Excess secretory products fuse with lysosomes ells known to spew secretory protein granules had been helpful in deciphering and defining the secretory pathway. But what happened when secretion systems were turned off? Lysosomes were known to degrade foreign proteins taken up by cells and even autodigest intracellular membranous structures—but what was the fate of excess endogenous protein? To a...

In a survey of the UV-brightest AGN using the Far Ultraviolet Spectroscopic Explorer (FUSE), we commonly find associated absorption in the O vi λλ1032, 1038 resonance doublet. Of 34 Type I AGN observed to date with z < 0.15, 16 show detectable O vi absorption. Most absorption systems show multiple components with intrinsic widths of ∼ 100 km s spread over a blue-shifted velocity range of < 1000...
