Self-management of context-aware overlay ambient networks

Ambient Networks (ANs) are dynamically changing and heterogeneous as they consist of potentially large numbers of independent, heterogeneous mobile nodes, with spontaneous topologies that can logically interact with each other to share a common control space, known as the Ambient Control Space. ANs are also flexible i.e. they can compose and decompose dynamically and automatically, for supporting the deployment of cross-domain (new) services. Thus, the AN architecture must be sophisticatedly designed to support such high level of dynamicity, heterogeneity and flexibility. We advocate the use of service specific overlay networks in ANs, that are created on-demand according to specific service requirements, to deliver, and to automatically adapt services to the dynamically changing user and network context. This paper presents a self-management approach to create, configure, adapt, contextualise, and finally teardown service specific overlay networks

We are all foreigners in an analogue world:Cyber-material alliances in contesting immigration control in Stockholm’s metro system

Public spaces are often contested sites involving the political use of socio-material arrangements to check, control and filter the flow of people. In Sweden, the recently established police project (REVA) in is an attempt to strengthen ‘internal border’ controls. This paper discusses the emergence of practices in which activist groups organized and performed resistance through the use of counter technologies in the transport sector. We explain how a hybrid alliance of human and nonhuman others generated new virtual and urban spaces and provided temporary autonomous zones, to groups of undocumented immigrants. REVA Spotter, for example, was a tool, a manifesto and a peaceful means of resistance to the REVA policing methods through continuous Facebook status updates on identity checks at metro stations in Stockholm. The technology enabled reports on location and time of ticket controls to warn travellers in real time. Attempts by authorities to exert control over the ‘spatial’ underground were thereby circumvented by the effective development of an alternative infrastructural ‘underground’ consisting of assemblages of technologies, activists, undocumented immigrants, texts and emails, smart phones and computers. Based on ‘netnographic observations’ and interviews, the paper utilizes the case of the REVA to illustrate processes and practices that simultaneously configure the powerful surveyor, the discriminated and those who contest these politics through hybridities of cyber/material, human/nonhuman and urban/virtual space. The paper argues that by configuring such hybrid alliances, activists provided cyber-material autonomy to undocumented immigrants and other travellers in the metro, thereby creating new virtual and urban spaces for mobility and flows.</p

Hox Genes, Digit Identities and the Theropod/Bird Transition

Vargas and Fallon (2005) propose that Hox gene expression patterns indicate that the most anterior digit in bird wings is homologous to digit 1 rather than to digit 2 in other amniotes. This interpretation is based on the presence of Hoxd13 expression in combination with the absence of Hoxd12 expression in the second digit condensation from which this digit develops (the first condensation is transiently present). This is a pattern that is similar to that in the developing digit 1 of the chicken foot and the mouse hand and foot. They have tested this new hypothesis by analysing Hoxd12 and Hoxd13 expression patterns in two polydactylous chicken mutants, Silkie and talpid2. They conclude that the data supports the notion that the most anterior remaining digit of the bird wing is homologous to digit 1 in other amniotes either in a standard phylogenetic sense, or alternatively in a (limited) developmental sense in agreement with the Frameshift Hypothesis of Wagner and Gautier (1997, i.e. that the developmental pathway is homologous to the one that leads to a digit 1 identity in other amniotes, albeit that it occurs in the second instead of the first digit condensation). We argue that the Hoxd12 and Hoxd13 expression patterns found for these and other limb mutants do not allow distinguishing between the hypothesis of Vargas and Fallon (2005) and the alternative one, i.e. the most anterior digit in bird wings is homologous to digit 2 in other amniotes, in a phylogenetic, or developmental sense. Therefore, at the moment the data on limb mutants does not present a challenge to the hypothesis, based on other developmental data (Holmgren 55, Hinchliffe 484, Burke and Feduccia 497, Kundrat et al. 2002, Larsson and Wagner 2002, Feduccia and Nowicki 2002), that the digits of bird wings are homologous to digits 2,3,4 in amniotes. We recommend further testing of the hypothesis by comparing Hoxd expression patterns in different taxa

A flexible information service for management of virtualized software-defined infrastructures

Summary There is a major shift in the Internet towards using programmable and virtualized network devices, offering significant flexibility and adaptability. New networking paradigms such as software-defined networking and network function virtualization bring networks and IT domains closer together using appropriate architectural abstractions. In this context, new and novel information management features need to be introduced. The deployed management and control entities in these environments should have a clear, and often global, view of the network environment and should exchange information in alternative ways (e.g. some may have real-time constraints, while others may be throughput sensitive). Our work addresses these two network management features. In this paper, we define the research challenges in information management for virtualized highly dynamic environments. Along these lines, we introduce and present the design details of the virtual infrastructure information service, a new management information handling framework that (i) provides logically centralized information flow establishment, optimization, coordination, synchronization and management with respect to the diverse management and control entity demands; (ii) is designed according to the characteristics and requirements of software-defined networking and network function virtualization; and (iii) inter-operates with our own virtualized infrastructure framework. Evaluation results demonstrating the flexible and adaptable behaviour of the virtual infrastructure information service and its main operations are included in the paper.

Why Five Fingers? Evolutionary Constraints on Digit Numbers

Evolutionary changes in the number of digits and other limb elements appear to be severely constrained, probably as a result of a low level of modularity during limb development. Reduced limb structures typically develop through a process of construction followed by destruction and amniotes have evolved many digit-like structures rather than actual extra digits. In amniotes, limb development occurs during the crucial phylotypic stage, when many inductive interactions are occurring throughout the body. As a result, changes in limb development usually engender changes in other body parts. Thus, mutations that change the number of limb bones are expected to have many pleiotropic effects, which severely reduces the chance of such mutations being successful. In amphibians with aquatic larvae, limb development occurs after the phylotypic stage and limb development is decoupled from the interactivity of the phylotypic stage. The constraint of pleiotropic effects is, therefore, expected to be weaker. This expectation agrees with the larger variability in the number of hand and foot structures in amphibians, with frogs even occasionally possessing six toes. These facts once again emphasize the importance of pleiotropic effects as constraints to evolutionary change, including their role in the conservation of body plans
