  • We present the percolation-theory model for explanation of conductivity of perovskites based on the scaling property of grain boundary formation. Assuming a two-layer simple effective medium model, composed of the grain itself as a first layer and the boundary as a second layer, it was modeled that the net resistivity r of the medium depends on the average grain size L, boundary thickness L’ and boundary fractal dimension D.

  • SLEκ is a random growth process based on Loewner’s equation with driving parameter a one-dimensional Brownian motion running with speed κ. This process is intimately connected with scaling limits of percolation clusters and with the outer boundary of Brownian motion, and is conjectured to correspond to scaling limits of several other discrete processes in two dimensions. The present paper attempts a first systematic study of SLE. It is proved that for all κ = 8 the SLE trace is a path; for κ ∈ [0, 4] it is a simple path; for κ ∈ (4, 8) it is...

  • Historically, most cancer research has been conducted through small independent projects initiated by individual investigators with relatively small research groups. Such research is driven by focused hypotheses addressing specific biological questions. There will always be a need for this traditional approach to research; in recent years, however, it has also become more feasible to undertake projects on a broader and larger scale, thereby developing extensive pools of data and research tools that can facilitate those more conventional efforts....

  • In this paper we present a method to group adjectives according to their meaning, as a first step towards the automatic identification of adjectival scales. We discuss the properties of adjectival scales and of groups of semantically related adjectives and how they imply sources of linguistic knowledge in text corpora. We describe how our system exploits this linguistic knowledge to compute a measure of similarity between two adjectives, using statistical techniques and without having access to any semantic information about the adjectives. ...

  • Do you want to grow mushrooms? There are plenty of reasons to do so. Mushrooms are a good cash crop; they are rather easy to grow and are brimming with protein, B vitamins and minerals. They even have medicinal properties. Time between spawning and harvesting can be as short as three weeks. Furthermore, after the cultivation, you can still use the substrate as a good soil conditioner. This Agrodok gives you detailed information on the cultivation of oyster, shiitake and wood ear mushrooms.

  • These unique characteristics plus the functionalities from the materials themselves impart nanofibers with a number of novel properties for applications in areas as various as biomedical engineering, wound healing, drug delivery and release control, catalyst and enzyme carriers, filtration, environment protection, composite reinforcement, sensors, optics, energy harvest and storage, and many others. More and more emphasis has recently been placed on large-scale nanofiber production, the key technology to the wide usages of nanofibers in practice....

  • Metamaterials, i.e. artificial materials with properties not found in nature (Caloz & Itoh, 2006; Marqués et al., 2008), have gained a lot of attention in the past decade. The virtually unlimited freedom in tailoring their constitutive parameters created hopes for the realization of unique devices, such as subwavelength lenses and invisibility cloaks, which were essentially impossible to achieve with classical materials.

  • Since the seminal study of Leland et al. [41] on the self-similar nature of network traf®c, signi®cant advances have been made in understanding the statistical properties of measured network traf®cÐin particular, Internet workloadsÐwhy self-similar burstiness is an ubiquitous phenomenon present in diverse networking contexts, mathematical models for their description and performance analysis based on queueing, and traf®c control and resource management under self-similar traf®c conditions.

  • When the field of microfluidics emerged in the early 1990s, it was primarily focused on the development of analytical microdevices. Since then, microfluidics has expanded its influence into virtually every branch of science and engineering. There are many driving forces behind this explosive growth. To name a few: • Scaling properties afforded by miniaturization are desirable for many applications. For example, enhanced mass transfer and heat dissipation enable faster chemical separations without sacrificing separation performance....

  • This chapter gives an overview of some properties of the storage occupancy process in a buffer fed with ``fractional Brownian traf®c,'' a Gaussian self-similar process. This model, called here ``fractional Brownian storage,'' is the logically simplest long-range-dependent (LRD) storage system having strictly self-similar input variation. The impact of the self-similarity parameter H can be very clearly illustrated with this model.

  • Nowadays, environmental issues including air and water pollution, climate change, overexploitation of marine ecosystems, exhaustion of fossil resources, conservation of biodiversity are receiving major attention from the public, stakeholders and scholars from the local to the planetary scales. It is now clearly recognized that human activities yield major ecological and environ- mental stresses with irreversible loss of species, destruction of habitat or cli- mate catastrophes as the most dramatic examples of their effects.

  • Network support for variable bit rate (VBR) video needs to consider (1) properties of workload induced (e.g., signi®cant autocorrelations into far lags and heterogeneous marginal distributions), and (2) application-speci®c bounds on delay-jitter and statistical cell-loss probabilities. This chapter presents a quality-of-service (QoS) solution for such traf®c at each multiplexing point in a network. Heterogeneity in both-offered workload and quality-of-service requirements are considered. The network is assumed to be cell-switched with virtual circuits (VCs)...
