Reactome (www.reactome.org) is a curated database describing very diverse biological processes in a computationally accessible format. The data is provided by experts in the field and subject to a peer review process. The core unit of the Reactome data model is the reaction. The entities participating in reactions form a network of biological interactions. Reactions are grouped into pathways. Reactome data are cross-referenced to a wide selection of publically available databases (such as UniProt, Ensembl, GO, PubMed), facilitating overall integration of biological data. In addition to the manually curated, mainly human reactions, electronically inferred reactions to a wide range of other species, are presented on the website. All Reactome reactions are displayed as arrows on a Reactionmap. The Skypainter tool allows visualisation of user-supplied data by colouring the Reactionmap. Reactome data are freely available and can be downloaded in a number of formats.

The ability to quickly deploy new protocols, and provide flexibility to both applications and network administrators has been an oft-cited reason for active networks to be seriously examined. This paper describes an architecture and implementation that provides dynamic installation of network services and flexibility to active code. An example of weighted fair queuing being installed dynamically into a running network is examined.

A general-purpose browser for directed graphs is described. The browser provides operations to examine and edit graphs and to generate a layout for a graph automatically that minimizes edge crossings. Two layout algorithms were implemented. A hierarchical graph layout algorithm was found to be best for directed graphs. The graph browser also has facilities that allow it to be integrated with other applications (e.g. a program browser). These facilities and our experiences building a program call-graph browser are described.

High-resolution and high frame rate dynamic microdisplays can be implemented by scanning a photon beam in a raster format across the viewer's retina. Microvision is developing biaxial MEMS scanners for such video display applications. This paper discusses the optical performance requirements for scanning display systems. The display resolution directly translates into a scan-angle-mirror-size product and the frame rate translates into vertical and horizontal scanner frequencies. (theta) -product and fh are both very important figures of merit for scanner performance comparison. In addition, the static and dynamic flatness of the scanners, off-axis motion and scan repeatability, scanner position sensor accuracy all have a direct impact on display image quality.

Efficient deep‐blue organic light‐emitting diodes were demonstrated using 4,4'‐bis(9‐ethyl‐3‐carbazovinylene)‐1,1'‐biphenyl doped in double‐emission layers (D‐EMLs). The D‐EML system, which consists of 2‐methyl‐9,10‐di(2‐naphthyl)anthracene and 1,4‐(dinaphthalen‐2‐yl)‐naphthalene as blue hosts, was employed to broaden the recombination zone and to ensure the good confinement of the holes and electrons. The optimized device showed a peak current efficiency of 4.47 cd/A, a peak external quantum efficiency of 4.09%, and Commission Internationale de L'Eclairage coordinates of (0.16, 0.10).

This paper examines how users negotiate their self-presentation via an avatar used in social media. Twenty participants customised an avatar while thinking aloud. An analysis of this verbal data revealed three motivating factors that drive self-presentation: (1) avatars were used to accurately reflect their owners’ offline self; participants chose to display stable self-attributes or idealised their avatar by concealing or emphasising attributes aligned to imagined social roles, (2) the diversity of customisation options was exploited by some participants who broke free from the social rules governing self-presentation offline; others used the avatar's appearance to emotionally provoke and engage the avatar viewer and finally, (3) avatars were used as proxies; participants designed their online self in order to convey a message to a significant other.

E-book reading devices open new possibilities in the field of reading. More activities than just reading a book can be performed with a single electronic device. For a long time, electronic reading devices have not been favored because their active LCD displays used to have a relatively low contrast. The new generation of electronic reading devices differs from earlier ones in the nature of the display: active LCD displays have been replaced with displays based on e-ink technology, which has display properties closer to that of printed paper. Moreover, e-ink technology has higher power efficiency, thereby increasing battery life and reducing weight. At first sight, the display looks similar to paper print, but the question remains whether the reading behavior also is equal to that of reading a printed book. In the present study, we analyzed and compared reading behavior on e-reader displays and on printed paper. The results suggest that the reading behavior on e-readers is indeed very similar to the reading behavior on print. Participants shared similar proportions of regressive saccades while reading on e-readers and print. Significant differences in fixation duration suggest that e-readers, in some situations, may even provide better legibility.► Reading behavior measured in eye movements on e-ink displays and print. ► Participants made significantly longer fixations when reading on a printed book. ► Participants made similar proportion of regressive saccades when reading on e-ink displays and print. ► Result shows that the reading behavior on e-ink-displays is very similar to the reading behavior on print. ► Overall the results suggest that the legibility of the current e-reader generation is good.

Here we show for the first time that the plasticity in morphology and duration of
yawning in Macaca tonkeana can be associated with different functional contexts.
Macaca tonkeana is classified as a tolerant macaque species characterized by social
interactions minimally constrained by dominance rank or kinship. Tonkean macaques,
as other egalitarian species, rely on a complex facial communicative system.
We found that the degree of mouth opening (ranging from covered to uncovered
tooth yawns) and the duration of yawning were not strictly dependent. The shortest
uncovered tooth yawns were associated with an intense locomotor/physical activity
and peaked immediately after stressful social events thus indicating an increase in
arousal. In contrast, longer yawns, independently from teeth exposure, were
primarily associated with a relaxed state of the subject. In conclusion, our study
suggests that to explore the potential different functions of yawning, it is necessary
to focus on the variability of its expression both in terms of morphology and
duration, because not all yawns tell the same story.

Streptococcus pyogenes (group A streptococcus, GAS) secretes streptokinase, a potent plasminogen activating protein. Among GAS isolates, streptokinase gene sequences (ska) are polymorphic and can be grouped into two distinct sequence clusters (termed cluster type-1 and cluster type-2) with cluster type-2 being further divided into sub-clusters type-2a and type-2b. In this study, far-UV circular dichroism spectroscopy indicated that purified streptokinase variants of each type displayed similar secondary structure. Type-2b streptokinase variants could not generate an active site in Glu-plasminogen through non-proteolytic mechanisms while all other variants had this capability. Furthermore, when compared with other streptokinase variants, type-2b variants displayed a 29- to 35-fold reduction in affinity for Glu-plasminogen. All SK variants could activate Glu-plasminogen when an activator complex was preformed with plasmin; however, type-2b and type-1 complexes were inhibited by α2-antiplasmin. Exchanging skatype-2a in the M1T1 GAS strain 5448 with skatype-2b caused a reduction in virulence while exchanging skatype-2a with skatype-1 into 5448 produced an increase in virulence when using a mouse model of invasive disease. These findings suggest that streptokinase variants produced by GAS isolates utilize distinct plasminogen activation pathways, which directly affects the pathogenesis of this organism.

ActiveCube is a novel user interface that allows intuitive interaction with computers. ActiveCube allows users to construct and interact with three-dimensional (3D) environments using physical cubes equipped with input/output devices. Spatial, temporal, and functional consistency is always maintained between the physical object and its corresponding representation in the computer. In this article we detail the design and implementation of our system. We describe the method we used to realize flexible 3D modeling by controlling the recognition signals of each face in each cube. We also explain how we integrated additional multimodal interaction options via a number of sophisticated I/O devices and the inclusion of a second microprocessor in our cubes. We argue that ActiveCube, with its current real-time multimodal and spatial capabilities, is ready to enable a large range of interactive entertainment applications that were impossible to realize before.
