Knowledge Acquisition and Processing System for Romanian Historical Documents

This paper presents ArhiNet, an integrated system for generating, processing and querying semantically enhanced archival eContent related to the middle age history of Transylvania, targeting cultural heritage preservation. The main workflows of the system aim to perform semantically enhanced eContent generation and knowledge acquisition, as well as knowledge processing and retrieval. Through knowledge acquisition, the relevant information is extracted from historical documents and structured as a domain ontology. In knowledge processing, the extracted ontological information is further processed and enhanced both through automatic reasoning and with the help of knowledge engineers. Finally, through knowledge retrieval, relevant documents and information are provided in response to natural language guided user queries.
A COREFERENTIALLY ANNOTATED CORPUS AND ANAPHORA RESOLUTION FOR CZECH

The paper presents an overview of a finished project focused on annotation of grammatical, pronominal and extended nominal coreference and bridging relations in the Prague Dependency Treebank (PDT 2.0). We give an overview of existing similar projects and their interests and compare them with our project. We describe the annotation scheme and the typology of coreferential and bridging relations and give the statistics of these types in the annotated corpus. Further we give the final results of the interannotator agreement with some explanations. We also briefly present the anaphora resolution experiments trained on the coreferentially annotated corpus and the future plans.
Rasl11b Knock Down in Zebrafish Suppresses One-Eyed-Pinhead Mutant Phenotype

The EGF-CFC factor Oep/Cripto1/Frl1 has been implicated in embryogenesis and several human cancers. During vertebrate development, Oep/Cripto1/Frl1 has been shown to act as an essential coreceptor in the TGFβ/Nodal pathway, which is crucial for germ layer formation. Although studies in cell cultures suggest that Oep/Cripto1/Frl1 is also implicated in other pathways, in vivo it is solely regarded as a Nodal coreceptor. We have found that Rasl11b, a small GTPase belonging to a Ras subfamily of putative tumor suppressor genes, modulates Oep function in zebrafish independently of the Nodal pathway. rasl11b down regulation partially rescues endodermal and prechordal plate defects of zygotic oep−/− mutants (Zoep). Rasl11b inhibitory action was only observed in oep-deficient backgrounds, suggesting that normal oep expression prevents Rasl11b function. Surprisingly, rasl11b down regulation does not rescue mesendodermal defects in other Nodal pathway mutants, nor does it influence the phosphorylation state of the downstream effector Smad2. Thus, Rasl11b modifies the effect of Oep on mesendoderm development independently of the main known Oep output: the Nodal signaling pathway. This data suggests a new branch of Oep signaling that has implications for germ layer development, as well as for studies of Oep/Frl1/Cripto1 dysfunction, such as that found in tumors.
The Effect of Probability Distributions on the Performance of Quantum Particle Swarm Optimization for Solving Dynamic Optimization Problems

The quantum particle swarm optimization (QPSO) algorithm was developed to address the limitations of the traditional particle swarm optimization (PSO) algorithm in dynamic environments. Some particles in the QPSO algorithm are chosen as "quantum" particles, and the positions of these are sampled uniformly within a radius (i.e., A hyper sphere) centred around the global best particle. The remainder of particles follow standard PSO behaviour. This paper proposes sampling various alternative probability distributions to update the positions of quantum particles. Ten probability distributions are examined on dynamic environments with varying dimensionalities, temporal change severities, and spatial change severities, with both single-peak and five-peak environments considered. Results indicated that the most effective distribution to use is dependent upon the type of dynamism present. In general, it was observed that a small quantum radius was preferable to a large radius, indicating that exploitation is more beneficial than exploration with regards to QPSO performance. Finally, despite having been commonly used in various QPSO applications, the performance of the uniform distribution was found to be sub-par.
Asynchronous multiple objective particle swarm optimisation in unreliable distributed environments

This paper examines the performance characteristics of both asynchronous and synchronous parallel particle swarm optimisation algorithms in heterogeneous, fault-prone environments. Algorithm convergence is measured as a function of both iterations completed and time elapsed, allowing the two particle update mechanisms to be comprehensively evaluated and compared in such an environment. Asynchronous particle updates are shown to negatively impact the convergence speed in regards to iterations completed, however the increased parallel efficiency of the asynchronous model appears to counter this performance reduction, ensuring the asynchronous update mechanism performs comparably to the synchronous mechanism in fault-free environments. When faults are introduced, the synchronous update method is shown to suffer significant performance drops, suggesting that at least partly asynchronous algorithms should be used in real-world environments where faults can regularly occur.
The Stellar Content Near the Galactic Center

High angular resolution J,H,K, and L images are used to investigate the stellar content within 6 arcsec of SgrA*. The data, which are complete to K ∼ 16, are the deepest multicolor observations of this region published to date. The mean locus of the (K,H −K) CMD varies across the field, a result that is attributed to differential reddening with amplitude ∆AV ∼ 15 mag. The reddening variations within 3 arcsec of SgrA* are significantly smaller than this, and the resolved members of the compact star cluster immediately surrounding SgrA* have photometric properties that are not significantly different from objects at larger radii. We find that sources in our field with published 2μm spectra showing either line emission or CO absorption occupy different sequences on the (K, J − K) CMD. The emission line stars, which fall along the most richly populated sequence, have redder J−K colors than stars in the Magellanic Clouds with similar spectroscopic characteristics, and evidence is presented that this is due to excess infrared emission in the spectrum of the GC sources. The photometric properties of the giant branch, which is defined by stars showing CO absorption, are similar to those of the giant branch in Baade’s Window (BW). The mean J −K color and peak K brightness of the red giant branch are both consistent with a metal-rich population having an age ∼ 10 Gyr, while the width of the giant branch on the (K, J −K) CMD is indicative of an age spread ∆log(t) ≤ 1 dex. Therefore, if the inner bulge contains an underlying population of stars with ages in excess of ∼ 10 Gyr, as is the case in BW, then the region within a few arcsec of SgrA* cannot contain a large population of giant branch stars younger than 1 Gyr. We also report the detection of a modest population of faint, blue sources with K ≥ 14. We speculate that these are bright main sequence stars at the distance of the GC, although spectra will be required to confirm this interpretation. Nevertheless, the photometric properties of the largely unresolved compact knot of stars immediately surrounding SgrA* provide indirect evidence to support the presence of a large population of faint blue stars. In particular, we confirm previous studies that measure a relatively blue color for this cluster.

Predicting the Impacts of Plantations on Catchment Water Balances Using the 3PG Forest Growth Model

Forest plantations for wood production are an increasingly important land use in Australia. It is important to be able to predict the impact of this expansion on surface water and groundwater resources which are under significant stress in many regions. A modelling approach is essential to account for the many interacting environmental and management factors which may influence plantation growth and water use.
Effectiveness of a life story work program on older adults with intellectual disabilities

Objective This study examines the effectiveness of a life story work program (LSWp) in older adults with mild-to-moderate levels of intellectual disability (ID). Methods Using a quasiexperimental design, this study assigned 60 older adults who were between 50–90 years old with mild-to-moderate levels of ID to receive either the LSWp (intervention group, N=32) or usual activities (control group, N=28) during a period of 6 months. Evaluation was made based on the outcomes assessed by the Mood Interest and Pleasure Questionnaire, the Vineland Adaptive Behavior Scales, and the Personal Wellbeing Index – ID. Results and conclusion LSWp shows potential for improving the quality of life and preventing the loss of interest and pleasure in older adults with ID. It also shows promise in enhancing their socialization skills. Patients with better communication abilities seemed to benefit more from the LSWp.
Mindful words: How do our stories change when we read about mindfulness? A narrative inquiry

This narrative inquiry tells the stories of four women who read an online blog about mindfulness for three weeks and shared their reflections of the experience. It investigates the role that reading plays in the development of mindfulness—a process that has not featured previously in the research literature. The women in this study were recruited via social media, and all were motivated to learn more about mindfulness and how it could have a positive effect on their daily lives. Data was collected via questionnaires on their understanding of mindfulness and their state of mind prior to, and following the completion of, the project. The women also submitted written reflections, based on their reading and experience of each blog post. Analysis involved coding the data and forming it into individual narratives, written in their own words. The narratives were then deconstructed to investigate their association to the transformative learning process—perspective, experience, reflection, meaning making, and interpretation. The results showed that the women did, indeed, have transformative learning experiences, although the sustainability of such change needs further investigation. Despite limitations, these stories suggest that reading about mindfulness deserves a higher profile—and that the use of a digital platform to host written mindfulness content has the potential to positively affect a wide audience.
Understanding navigation and disorientation in hypermedia learning environments

Difficulties with orientation are common in hyperdocuments. This paper describes an exploratory study into the role of a navigation map, as a helping tool, during browsing processes. We tried to establish the influence of this navigational tool, provided by a hypermedia prototype, in retrieval tasks. Twenty-two students tested this prototype and some data were collected: scores obtained in a task-test and a record of the path followed by the subjects. With these data we defined a set of ratios as an attempt to understand the subjects’ browsing processes. Findings suggest that the map was not effective in the ameliorative role. Perhaps it is not wise to assume that a map that helps performance in a spatial context also forms an aid in a hypermedia environment under a nonhierarchical model.
Torso Inclination Enables Faster Walking in a Planar Biped Robot With Passive Ankles

There is a category of biped robots that are equipped with unactuated or passive ankles. We call them passive ankle walkers (PAWs). Because the unactuated ankle cannot provide the push-off at the end of stance phase as human ankles do, fast walking in PAWs is more challenging. In this paper, in order to realize fast walking in PAWs, we propose a simple strategy-torso inclination. To test this strategy, we studied a PAW model with simulation and prototype experiments. The simulation has shown how the torso inclination affects the walking speed and the energy efficiency of the PAW. Considering the “reality gap” problem of simulation, we have also experimentally tested this strategy with a real robot. By analyzing both the simulated model and the experimental results of the real robot, we identified the mechanism that accounts for fast walking in torso-inclined PAW.
Enriching entity grids and graphs with discourse relations: the impact in local coherence evaluation

This paper describes how discursive knowledge, given by the discursive theories RST (Rhetorical Structure Theory) and CST (Crossdocument Structure Theory), may improve the automatic evaluation of local coherence in multi-document summaries. Two of the main coherence models from literature were incremented with discursive information and obtained 91.3% of accuracy, with a gain of 53% in relation to the original results.
Beyond Stippling  — Methods for Distributing Objects on the Plane

Conventionally, stippling is an effective technique for representing surfaces in pen‐and‐ink. We present new efficientmethods for stipple drawings by computer. In contrast to already existing techniques, arbitrary shapes canbe used in place of dots. An extension of Lloyd's Method enables us to position small objects on a plane in a visuallypleasing form. This allows us to generate new illustration styles. Similar methods can be used for positioningobjects in other applications.
An Investigation Into the Universality of Sexual Symbolism.

Freud contended that genitalia will be represented in dreamsj art and similar modes (e.g. myth) by symbolic objects which are similar in shape to genital objects. Male genitalia will be represented by elongated objects (e.g. flagpoles, spears) while female genitalia will be represented by rounded enclosing objects (e.g. circles, rings). VJhile Freud's hypothesis concerning the isomorphism between genital shape and symbolic representation has been supported by studies in western cultures, it has not been adequately demonstrated to be valid with a variety of other cultures. The intent of the present research was to investigate the extent to which Freud's symbolism theory held with a variety of cultures and to investigate variables which ascounted for the presence or absence of Freud's views on symbolism in these cultures. In this investigation, four sets of sex symbols were presented to subjects from various cultural backgrounds by means of a . 3 5 mm slide projector at the rate of one second per symbol. Ss were to identify each symbol by recording
Rule-Based On-the-fly Web Spambot Detection Using Action Strings

spambots are a new type of internet robot that spread spam content through Web 2.0 applications like online discussion boards, blogs, wikis, social networking platforms etc. These robots are intelligently designed to act like humans in order to fool safeguards and other users. Such spam content not only wastes valuable resources and time but also may mislead users with unsolicited content. Spam content typically intends to misinform users (scams), generate traffic, make sales (marketing/advertising), and occasionally compromise parties, people or systems by spreading spyware or malwares. Current countermeasures do not effectively identify and prevent web spambots. Proactive measures to deter spambots from entering a site are limited to question / response scenarios. The remaining efforts then focus on spam content identification as a passive activity. Spammers have evolved their techniques to bypass existing anti-spam filters. In this paper, we describe a rule-based web usage behaviour action string that can be analysed using Trie data structures to detect web spambots. Our experimental results show the proposed system is successful for on-the-fly classification of web spambots hence eliminating spam in web 2.0 applications.
The acute effects of repeated static apnea on aerobic power

Purpose: Apnea exercises cause a rise in hematocrit, erythropoietin, hemoglobin concentration, lung volume and oxygen store in muscle and blood, and a decrease in blood acidosis and oxidative stress. These types of physiological changes that occur in the body result in developments in both time to exhaustion and V02max. The purpose of the current study was to investigate the acute effect of repeated static apneas on aerobic power. Material: Twenty physically active male university students (age:22.80±3.84 year, height:177.40±7.49 cm and weight:68.20±8.72 kg) volunteered to participate in the current study. They were divided as the static apnea and control groups randomly. The static group performed multistage exercise treadmill test to exhaustion (maximal aerobic power) after three maximal apneas with 2-min interval in sitting position. The control group performed only the maximal aerobic power test without apnea. Their maximal oxygen consumption (Vo2max), gas exchange rate (RER), heart beat rate (HR) and rate of perceived exertion (RPE) values were measured during maximal aerobic test. Their hemoglobin (Hb) and hematocrit (Hct) values were measured before and immediately after the apnea for both groups. Results: There were no significant differences found between the control and static apnea groups for Vo2max, HR, Hb and Hct. However, RPE values measured after the static apnea were lower (17.55±0.51) than the control (18.75±0.62). Conclusions: The repeated static apneas immediately prior the maximal aerobic effort cannot increase aerobic power in untrained breath hold participants. However, the lower RPE after static apnea may be used as an ergogenic effect.
An upper bound on the estimation error of the sparsest solution of underdetermined linear systems

Let A be an n X m matrix with m > n, and suppose the underdetermined linear system As = x admits a unique sparse solution s0 (i.e. it has a solution s0 for which ks0k0 < 1 2 spark(A)). Suppose that we have somehow a solution (sparse or non-sparse) ^s of this system as an estimation of the true sparsest solution s0. Is it possible to construct an upper bound on the estimation error k^s - s0k2 without knowing s0? The answer is positive, and in this paper we construct such a bound which, in the case A has Unique Representation Property (URP), depends on the smallest singular value of all n X n submatrices of A.
Voltage island-driven floorplanning

Energy efficiency has become one of the most important issues to be addressed in today's system-on-a-chip (SoC) designs. One way to lower the power consumption is to reduce the supply voltage. Multi-supply voltage (MSV) is thus introduced to provide higher flexibility in controlling the power and performance trade-off. In region-based MSV, circuits are partitioned into "voltage islands" where each island occupies a contiguous physical space and operates at one supply voltage. These tasks of island partitioning and voltage level assignments should be done simultaneously in the floorplanning process in order to take those important physical information into consideration. In this paper, we consider this core-based voltage island driven floorplanning problem including islands with power down mode, and propose a method to solve it. Given a candidate floorplan solution represented by a normalized Polish expression, we are able to obtain optimal voltage assignment and island partitioning (including islands with power down mode) simultaneously to minimize the total power consumption. Simulated annealing is used as the basic searching engine. By using this approach, we can achieve significant power savings (up to 50%) for all data sets, without any significant increase in area and wire length. Our floorplanner can also be extended to minimize the number of level shifters between different voltage islands and to simplify the power routing step by placing the islands in proximity to the corresponding power pins.
Resilient architecture (preliminary version)

The main objectives of WP2 are to define a resilient architecture and to develop a range of middleware solutions (i.e. algorithms, protocols, services) for resilience to be applied in the design of highly available, reliable and trustworthy networking solutions. This is the first deliverable within this work package, a preliminary version of the resilient architecture. The deliverable builds on previous results from WP1, the definition of a set of applications and use cases, and provides a perspective of the middleware services that are considered fundamental to address the dependability requirements of those applications. Then it also describes the architectural organisation of these services, according to a number of factors like their purpose, their function within the communication stack or their criticality/specificity for resilience. WP2 proposes an architecture that differentiates between two classes of services, a class including timeliness and trustworthiness oracles, and a class of so called complex services. The resulting architecture is referred to as a “hybrid architecture”. The hybrid architecture is motivated and discussed in this document. The services considered within each of the service classes of the hybrid architecture are described. This sets the background for the work to be carried on in the scope of tasks 2.2 and 2.3 of the work package. Finally, the deliverable also considers high-level interfacing aspects, by providing a discussion about the possibility of using existing Service Availability Forum standard interfaces within HIDENETS, in particular discussing possibly necessary extensions to those interfaces in order to accommodate specific HIDENETS services suited for ad-hoc domains.
A Tool to Support Finding Favorite Music by Visualizing Listeners' Preferences

In recent years, music-finding services have been increasing. If we have explicit information specifying pieces of music, we can find music to our taste using such services. This paper describes a tool to support music discovery. The tool visualizes a relational structure among music genres and the music-preference data of many listeners to make the users aware of their favorite music without explicit information. A case study is described to illustrate the usefulness of the tool.
Iterative channel and data estimation: Framework and analysis via replica method

The large system analysis of a randomly spread direct-sequence code-division multiple-access system operating over a frequency-selective fading channel is considered. Iterative multiuser detection and decoding based on generalized posterior mean estimation and interference cancellation is assumed. The channel is mismatched and provided by a linear estimator whose initial pilot-based decisions are iteratively refined by using a feedback from the single-user decoders. By an application of the replica method, a tool from statistical physics, and density evolution with Gaussian approximation, we show that the performance metrics of the considered multiuser system converge in distribution at the large system limit to that of a simple single-user system operating over a flat fading channel. We also give the exact result of the hard decision feedback based channel estimator analyzed approximately by Li et al. (2007).
