Hypothesis: The ecological theory of adaptive radiation predicts divergent morphological adaptations to different environments, and different evolutionary trait utilities in varying environments. Organism: Darwin’s Small Ground Finch (Geospiza fuliginosa). Times and places: Santa Cruz Island, Galapagos Archipelago, in two study areas of different habitat type: highland forest (c. 500 m elevatio...

The article describes the studies’ results of steels with applied boron-based hardsurfacing overlays. overlay was done in four different ways. materials obtained differed chemical composition, properties and wear resistance. A detailed technical process surfacing charge which makes it possible to obtain necessary material, is given. Studies hardness, macro- microstructure, X-ray phase compositi...

Drifting Overlays are dynamic partial network-layer overlays with traffic ‘safe houses’ that enterprises can use to control, at fine granularity, the reachability and predictability of paths taken to important hosts. Drifting Overlays enable enterprises a level of control over their own DDoS defenses and routing choices, rather than leaving them at the mercy of their ISPs. KeywordsVPNs, Securit...

Overlays are an important tool for deploying new services on the Internet. However, the existing overlays are statically configured. For fault tolerance, ease of management, and efficiency it is crucial that overlays be self-organizing. We present a distributed algorithm to automatically configure the nodes into a logical topology which is dynamic and efficient.

We consider the problem of migrating user data between data centers. We introduce distributed storage overlays, a simple abstraction that represents data as stacked layers in different places. Overlays can be readily used to cache data objects, migrate these caches, and migrate the home of data objects. We implement overlays as part of a key-value object store called Nomad, designed to span man...

Developing new treatments for chronic obstructive pulmonary disease (COPD) is extremely challenging. This disease, chronic by definition, becomes apparent only after substantial-and probably irreversible-tissue damage has occurred. The observable phenotype is of a stable disease state whose progression is hard to influence and reversal of which appears almost impossible. Identifying key compone...

1. Introduction This paper discusses the integration of constraint actors to the Conceptual Programming (CP) environment (Hartley 1988) developed at CRL. The CP system is an implementation of Conceptual Graphs (Sowa 1984) with an added layer called procedural overlays. These overlays allow the system to represent temporal and causal information using a temporal calculus and related time maps (s...
