  • Proteins are the driving force for all cellular processes. They regulate several cellular events through binding to different partners in the cell. They are capable of binding to other proteins, peptides, DNA, and also RNA. These interactions are essential in the regulation of cell fates and could be important in drugs development. For example RNA interacting proteins regulate gene expression through the binding to different mRNAs. These mRNAs could be involved in important cellular processes such as cell survival or apoptosis.

  • Protein phosphorylation is a reversible posttranslational modification catalyzed by protein kinases and reversely by protein phosphatases. There are about 500 protein kinases and 25-30 phosphatases in human genome. Each kinase and phosphatase targets multiple substrates. Thus, protein phosphorylation is a most versatile signaling regulatory mechanism and constitutes a most complicated signaling network in living organisms. In fact, protein phosphorylation governs all aspects of physiological and pathological processes in human health....

  • Port scanners, such as nmap8 (see Appendix B for more information), first identify active hosts in the address range specified by the user using Transport Control Protocol/Internet Protocol (TCP/IP) Internet Control Message Protocol (ICMP) ECHO and ICMP ECHO_REPLY packets. Once active hosts have been identified, they are scanned for open TCP and User Datagram Protocol (UDP) ports 9 that will then identify the network services operating on that host.

  • Nowadays, with over a thousand bacterial genomes sequenced, even greater opportunities have opened for experimental or computational global analysis of metabolism, physiology, and evolution. In particular, the access to comprehensive sets of molecular components (genes, proteins, regulatory signals) is at the basis of the development of novel integrative approaches, aiming at understanding the function of specific sets of these components (operons, regulons, metabolic pathways, protein complexes, etc.) in the context of the whole organism.

  • DoS attacks are particularly malicious because although they do not provide intruders with access to specific data, they “tie up” IS resources, preventing legitimate users from accessing applications. They are usually achieved by hackers sending large amounts of jumbled or otherwise unmanageable data to machines that are connected to corporate networks or the Internet. Even more malicious are Distributed Denial of Service (DDoS) attacks in which an attacker compromises multiple machines or hosts.

  • In this series of four minireviews the field of scaffold proteins and proteins of similar molecular⁄cellular functions is overviewed. By binding and bring-ing into proximity two or more signaling proteins, these proteins direct the flow of information in the cell by activating, coordinating and regulating signaling events in regulatory networks.

  • We present an approach using syntactosemantic rules for the extraction of relational information from biomedical abstracts. The results show that by overcoming the hurdle of technical terminology, high precision results can be achieved. From abstracts related to baker’s yeast, we manage to extract a regulatory network comprised of 441 pairwise relations from 58,664 abstracts with an accuracy of 83–90%. To achieve this, we made use of a resource of gene/protein names considerably larger than those used in most other biology related information extraction approaches. ...

  • An extended range of new sensing applications and solutions have emerged in different fields such as rural and forest fire detection [1], monitoring of industrial manufacturing processes [2], transport/logistics [3], and for personal services in areas such as healthcare and Ambient Assisted Living (AAL) [4]. These new advanced applications based on a new generation of sensing and communication capabilities are a consequence of the continuous advances in sensor technologies and wireless communication protocols that allow for greater autonomy of sensor nodes.

  • Here we study the architecture and characteristics of the broker network. We are using a particular internal structure for the events (defined in XML but currently implemented as a Java object). We assume a sophisticated matching of publishers and subscribers defined as general topic objects (defined by an XML Schema that we have designed). However these are not the central issues to be discussed here.

  • It was the best of times; it was the worst of times. A decade ago the science fiction author David Brin published the Transparent Society.1 It was his tale of two cities, set 20 years in the future. Brin had a vision, or rather he had two. He had foreseen, more clearly than most, the coming ubiquity of a “surveillance society” and he posited two very polarised outcomes. Brin decided to pose the reader a straight choice: Which of these two outcomes do you want? Brin told of two cities twenty years hence. From a distance both cities look very alike....

  • The current nutritional and health profiles of the Mexican population reflect notable failures in the field of social policies. Protein-energy malnutrition and infectious diseases are still relevant public health matters among poor rural and urban populations, and they remain common causes of death during infancy and childhood, and even later in life.

  • Perimeter security solutions control access to critical network applications, data, and services so that only legitimate users and information can pass through the network. This access control is handled by routers and switches with access control lists (ACLs) and by dedicated firewall appliances. A firewall provides a barrier to traffic crossing a network’s “perimeter” and permits only authorized traffic to pass, according to a predefined security policy. Complementary tools, including virus scanners and content filters, also help control network perimeters.

  • The Bundesbank is in practice the only means - other than relying on their competitors - for smaller private banks without a giro network of their own to execute payments intended for other banks on behalf of their customers. Since 1982 a combined private national payment transaction company has existed for the German banking sector, Gesellschaft für Zahlungssysteme mbH (GZS). This is an independent processing company which ensures the low-cost handling of card-protected payments and develops new electronic payment systems.

  • Soon after the first sequences of proteins and nucleic acids became available for comparative analysis, it became apparent that they can play a key role for reconstructing the evolution of life. The availability of the sequence of several proteins prompted the birth of the field of molecular evolution, which aims at both the reconstruction of the biochemical history of life and the understanding of the mechanisms of evolution at the molecular level through the analysis of the macromolecules of existing organisms.

  • Cells respond to environmental cues through a complex and dynamic network of signaling pathways that normally maintain a critical balance between cellular proliferation, differentiation, senescence, and death. One current research challenge is to identify those aberrations in signal transduction that directly contribute to a loss of this division-limited equilibrium and the progression to malignant transformation. The study of cell-signaling molecules in this context is a central component of cancer research.

  • Priority is given to books and book series that have relatively greater citation impact. Book Citation Index now covers over 150 highly cited book series in Science, Social Science, and Arts & Humanities. Journal and proceedings citations to books in these series indicate that they are well-integrated into the scholarly communication network. The Book Citation Index uncovers another dimension of this network by opening citation pathways leading to and from publications in the wider world of books.

  • Relevant floor plans can be generated before planning the layout of furniture pieces. Recently, Merrell et al. [2010] proposed a data- driven method to generate residential building layouts. In their work, 120 examples of architectural programs are used to train a Bayesian network that captures the relationships among different rooms. Given certain user requirements as priors, the Bayesian net- work can then be used to generate a floor plan, which is iteratively modified to incorporate desirable human factors. The result is a synthesized floor plan for a residential building.
