Extraction of semantic relations from a Basque monolingual dictionary using Constraint Grammar

This paper deals with the exploitation of dictionaries for the semi-automatic construction of lexicons and lexical knowledge bases. The final goal of our research is to enrich the Basque Lexical Database with semantic information such as senses, definitions, semantic relations, etc., extracted from a Basque monolingual dictionary. The work here presented focuses on the extraction of the semantic relations that best characterise the headword, that is, those of synonymy, antonymy, hypernymy, and other relations marked by specific relators and derivation. All nominal, verbal and adjectival entries were treated. Basque uses morphological inflection to mark case, and therefore semantic relations have to be inferred from suffixes rather than from prepositions. Our approach combines a morphological analyser and surface syntax parsing (based on Constraint Grammar), and has proven very successful for highly inflected languages such as Basque. Both the effort to write the rules and the actual processing time of the dictionary have been very low. At present we have extracted 42,533 relations, leaving only 2,943 (9%) definitions without any extracted relation. The error rate is extremely low, as only 2.2% of the extracted relations are wrong.
Face Detection and Tracking from Image and Statistics Gathering

This article deals with facial detection and tracking algorithm development. The most efficient method for facial monitoring, namely, template matching technique, was found by considering different tracking techniques. The authors enumerate main drawbacks of the template tracking and improve the algorithm according to the problem set. The following modifications to the template matching method were developed: template averaging, face loss at image edges, scaling the image according to the eye to eye distance, scaling by means of face search, color histogram check and lost face recovery. The article also provides results of functional and stress tests of the tracking algorithm developed.
Self-Concept – Performance Congruence: An Exploration of Patterns among High-Achieving Adolescents

Self-concept to performance congruence among academically able adolescents (54 females, 49 males) in both math and English was explored. Although analyses revealed similar congruence patterns for females and males in both subject-matter areas, the overall majority of these able learners fell outside the congruent range. These findings suggest that, regardless of gender or content area, able adolescents may be at risk for unrealistic self-concept perceptions relative to their actual performance.
LMO4 is an Essential Cofactor in the Snail2-Mediated Epithelial-to-Mesenchymal Transition of Neuroblastoma and Neural Crest Cells

Neuroblastoma is an embryonic tumor derived from cells of the neural crest. Taking advantage of a newly developed neural crest lineage tracer and based on the hypothesis that the molecular mechanisms that mediate neural crest delamination are also likely to be involved in the spread of neuroblastoma, we were able to identify genes that are active both in neural crest development and neuroblastoma tumor formation. A subsequent search of the neuroblastoma gene server for human orthologues of genes differentially expressed in the chick embryo neural crest screen retrieved the LIM domain only protein 4 (LMO4), which was expressed in both cell types analyzed. Functional experiments in these two model systems revealed that LMO4 activity is required for neuroblastoma cell invasion and neural crest delamination. Moreover, we identified LMO4 as an essential cofactor in Snail2-mediated cadherin repression and in the epithelial-to-mesenchymal transition of both neural crest and neuroblastoma cells. Together, our results suggest that the association of high levels of LMO4 with aggressive neuroblastomas is dependent on LMO4 regulation of cadherin expression and hence, tumor invasiveness.
Repression of the Transcription Factor Th-POK by Runx Complexes in Cytotoxic T Cell Development

Mouse CD4+CD8+ double-positive (DP) thymocytes differentiate into CD4+ helper-lineage cells upon expression of the transcription factor Th-POK but commit to the CD8+ cytotoxic lineage in its absence. We report the redirected differentiation of class I–restricted thymocytes into CD4+CD8– helper-like T cells upon loss of Runx transcription factor complexes. A Runx-binding sequence within the Th-POK locus acts as a transcriptional silencer that is essential for Th-POK repression and for development of CD8+ T cells. Thus, Th-POK expression and genetic programming for T helper cell development are actively inhibited by Runx-dependent silencer activity, allowing for cytotoxic T cell differentiation. Identification of the transcription factors network in CD4 and CD8 lineage choice provides insight into how distinct T cell subsets are developed for regulating the adaptive immune system.
Fruits and vegetables that are sources for lutein and zeaxanthin: the macular pigment in human eyes

BACKGROUND It has been suggested that eating green leafy vegetables, which are rich in lutein and zeaxanthin, may decrease the risk for age related macular degeneration. The goal of this study was to analyse various fruits and vegetables to establish which ones contain lutein and/or zeaxanthin and can serve as possible dietary supplements for these carotenoids. METHODS Homogenates of 33 fruits and vegetables, two fruit juices, and egg yolk were used for extraction of the carotenoids with hexane. Measurement of the different carotenoids and their isomers was carried out by high performance liquid chromatography using a single column with an isocratic run, and a diode array detector. RESULTS Egg yolk and maize (corn) contained the highest mole percentage (% of total) of lutein and zeaxanthin (more than 85% of the total carotenoids). Maize was the vegetable with the highest quantity of lutein (60% of total) and orange pepper was the vegetable with the highest amount of zeaxanthin (37% of total). Substantial amounts of lutein and zeaxanthin (30–50%) were also present in kiwi fruit, grapes, spinach, orange juice, zucchini (or vegetable marrow), and different kinds of squash. The results show that there are fruits and vegetables of various colours with a relatively high content of lutein and zeaxanthin. CONCLUSIONS Most of the dark green leafy vegetables, previously recommended for a higher intake of lutein and zeaxanthin, have 15–47% of lutein, but a very low content (0–3%) of zeaxanthin. Our study shows that fruits and vegetables of various colours can be consumed to increase dietary intake of lutein and zeaxanthin.
Mouse CD94/NKG2A Is a Natural Killer Cell Receptor for the Nonclassical Major Histocompatibility Complex (MHC) Class I Molecule Qa-1b

Natural killer (NK) cells preferentially lyse targets that express reduced levels of major histocompatibility complex (MHC) class I proteins. To date, the only known mouse NK receptors for MHC class I belong to the Ly49 family of C-type lectin homodimers. Here, we report the cloning of mouse NKG2A, and demonstrate it forms an additional and distinct class I receptor, a CD94/NKG2A heterodimer. Using soluble tetramers of the nonclassical class I molecule Qa-1b, we provide direct evidence that CD94/NKG2A recognizes Qa-1b. We further demonstrate that NK recognition of Qa-1b results in the inhibition of target cell lysis. Inhibition appears to depend on the presence of Qdm, a Qa-1b-binding peptide derived from the signal sequences of some classical class I molecules. Mouse NKG2A maps adjacent to CD94 in the heart of the NK complex on mouse chromosome six, one of a small cluster of NKG2-like genes. Our findings suggest that mouse NK cells, like their human counterparts, use multiple mechanisms to survey class I expression on target cells.
The Ubiquitin-Proteasome Pathway and Plant Development

The importance of the ubiquitin-proteasome pathway to cellular regulation in eukaryotes has become increasingly apparent during the last several years. This fact was formally acknowledged recently by the awarding of the 2004 Nobel Prize in Chemistry to Aaron Ciechanover, Avram Hershko, and Irwin
Comparative Topic Analysis of Japanese and Chinese Bloggers

This paper first studies how to apply a topic model to Chinese and Japanese blog posts collected from a few hundred Chinese and Japanese bloggers and then to classify bloggers into topics. The estimated topics are exploited in the task of over viewing the Chinese and Japanese bloggers' concerns, opinions, and cultures. Those topics are also quite helpful when comparing them between Chinese and Japanese in order to discover differences in the concerns, opinions, and cultures of the two languages. In the evaluation, we collect a few hundred bloggers from a well-known Sina blog host bloggers categories in China, and an also well-known blogger community service Nihon Blog Mura in Japan. As case studies, we focus on the "health", "military", and "nursing care" categories in the services of both languages, and generate topics based on a topic model, and then overview and compare them between Chinese and Japanese. We actually discover certain differences in bloggers' topics between Chinese and Japanese.
Search for Strange Pentaquark Production in e + e − Annihilations at √ s = 10.58 GeV and in Υ(4S) Decays The BABAR Collaboration

We present a preliminary inclusive search for strange pentaquark production in e + e − interactions at a center-of-mass energy of 10.58 GeV using 123 fb −1 of data collected with the BABAR detector. We look for the states that have been reported previously: the Θ + (1540), interpreted as a udud¯ s state; and the Ξ −− (1860) and Ξ 0 (1860), candidate dsds¯ u and uss(u¯ u + d ¯ d) states, respectively. In addition we search for other members of the antidecuplet and corresponding octet to which these states are thought to belong. We find no evidence for the production of such states and set preliminary limits on their production cross sections as functions of c.m. momentum. The corresponding limits on the Θ + (1540) and Ξ −− (1860) rates per e + e − → q ¯ q event are well below the rates measured for ordinary baryons of similar mass.
Development of a multichannel temperature and humidity monitoring device

Environmental temperature and humidity levels have impacts on organisms and therefore care is taken to measure/monitor and maintain them at certain levels in daily life. In this study, a portable multichannel temperature and humidity monitoring device has been developed. The device houses multiple temperature sensors, a humidity sensor, a microcontroller, a display and a +9V battery. Tests with three temperature sensors show that the device is user-friendly and performs consistent measurements. The device is able to operate thirty-six sensors at maximum and can transfer measurement results to any personal computer or Bluetooth device with universal asynchronous receiver input.
Smart Files: Combining the Advantages of DBMS and WfMS with the Simplicity and Flexibility of Spreadsheets

Even though database management as well as workflow management systems have significant advantages, spreadsheets exchanged by e-mail are still in widespread use for many processes within an enterprise, causing problems such as poor data-quality and lack of process monitoring. This paper analyzes reasons for office-document based workflows (ODBWf) and presents an alternative solution that combines the advantages of DBMS and WfMS with the flexibility and simplicity of office documents. This paper introduces an autonomous mobile document-management-system based on a ‘smart’ file. This file is executable and contains a managed resource part where files can be stored. Any read/write access to its resource part is managed by the file itself; it controls who can do what and automatically synchronizes changes to other systems such as process-monitoring or business intelligence tools. Proven concepts from DBMS, such as triggers, integrity constraints and multi-user support are utilized to improve ODBWfs without restraining their flexibility.
The Wrong Solution to the Teacher Shortage.

In recent years, researchers and policymakers have told us again and again that severe teacher shortages confront schools. They point to a dramatic increase in the demand for new teachers resulting from two converging demographic trends: increasing student enrollments and increasing numbers of teachers reaching retirement age. Shortfalls of teachers, they say, are forcing many school systems to lower their standards for teacher quality (National Commission on Teaching and America's Future, 1997).

Optimum ergodic beamforming capacity in urban microcellular operational environments

In the present paper, the optimum beamforming transmission scheme, in terms of ergodic beamforming capacity maximization, and the necessary-sufficient optimality of beam-forming condition under the MIMO combined CMI-CCI model (correlated Rician MIMO channels) are studied through simulations, providing results for an urban microcellular operational environment with a Line of Sight (LOS) component. The channel is produced using the spatial channel model proposed by 3GPP in [1] and two different channel feedback information models are considered: the short and the long term feedback model. Results indicate that optimum beamforming is the ergodic capacity maximizing spatial transmit pre-coding scheme in the context both feedback models. Moreover, the optimum beamformer is compared to the max SNR Beamformer, which seems to have near-optimum ergodic (beamforming) capacity performance.
Ranking Web Search Results from Personalized Perspective

In this paper, we exploit the technique of data mining to mine frequent access patterns from user browsing behavior. In light of frequent access patterns, we develop a solution procedure to automatically extract user interests. Furthermore, in accordance with user interests mined and feedbacks of users, we propose a new algorithm with the idea of dynamically adjusting the ranking scores of Web pages. Specifically, algorithm PPR (standing for personalized PageRank), is divided into four phases. The first phase assigns the initial weights based on user interests. In the second phase, the virtual links and hubs are created according to user interests. By observing user click streams, our proposed algorithm will incrementally reflect user favors for the personalized ranking in the third phase. To improve the accuracy of ranking, collaborative filtering is taken into consideration when the new query is submitted. By conducting simulation experiments, we have shown that algorithm PPR is not only very effective but also very adaptive in providing personalized ranking to users
Videoscapes

The abundance of mobile devices and digital cameras with video capture makes it easy to obtain large collections of video clips that contain the same location, environment, or event. However, such an unstructured collection is difficult to comprehend and explore. We propose a system that analyzes collections of unstructured but related video data to create a Videoscape: a data structure that enables interactive exploration of video collections by visually navigating -- spatially and/or temporally -- between different clips. We automatically identify transition opportunities, or portals. From these portals, we construct the Videoscape, a graph whose edges are video clips and whose nodes are portals between clips. Now structured, the videos can be interactively explored by walking the graph or by geographic map. Given this system, we gauge preference for different video transition styles in a user study, and generate heuristics that automatically choose an appropriate transition style. We evaluate our system using three further user studies, which allows us to conclude that Videoscapes provides significant benefits over related methods. Our system leads to previously unseen ways of interactive spatio-temporal exploration of casually captured videos, and we demonstrate this on several video collections.
Integrated micro-solar cell structures for harvesting supplied microsystems in 0.35-µm CMOS technology

In this paper we present a solar harvester test chip, realized to characterize several integrated solar cell structures, gathering the information required to design a complete power management system for handling the harvested energy. In particular, we realized photodiodes with three different geometries of the p-diffusion, and three different dimensions of the n-well. The chip is realized in a 0.35-µm CMOS technology, and the diodes feature different active area density, depending on the geometry of the p-diffusions. In order to evaluate the harvesting performance of the solar cells in real applications, we developed an equivalent circuit of the devices, based on the experimental data and we used it to design a power management system specific for discrete-time applications. The power management system is being integrated on the same chip of the micro solar cells, in a 0.35-µm CMOS technology.
Bankruptcy and the Collateral Channel

Do bankrupt firms impose negative externalities on their non-bankrupt competitors? We propose and analyze a collateral channel in which a firm's bankruptcy reduces collateral values of other industry participants, thereby increasing the cost of external debt finance industry wide. To identify this collateral channel, we use a novel dataset of secured debt tranches issued by U.S. airlines which includes a detailed description of the underlying assets serving as collateral. Our estimates suggest that industry bankruptcies have a sizeable impact on the cost of debt financing of other industry participants. We discuss how the collateral channel may lead to contagion effects which amplify the business cycle during industry downturns.
Regulation of the Human Interleukin-5 Promoter by Ets Transcription Factors

Interleukin-5 (IL-5), expressed primarily by type-2 T helper (Th2) cells, plays an important role in the development of allergic diseases, such as allergic asthma. Studying the regulation of IL-5 gene expression by Ets transcription factors, we found that Ets1 and Ets2, but not Elf-1, were able to activate the human IL-5 promoter in Jurkat T-cells. This required the presence of either phorbol 12-myristate acetate (PMA) plus ionomycin or PMA plus the viral protein HTLV-I Tax1. By mutation studies, it could be shown that Ets1 and Ets2 exerted their effects on the IL-5 promoter through a GGAA motif within the Cle0 element. In myeloid Kasumi cells, Ets1 and Ets2 failed to stimulate IL-5 promoter activity, unless the T-cell specific transcription factor GATA3 was added. These results show, for the first time, that Ets1 and Ets2 are able to cooperate with GATA3. Both ionomycin and Tax1 increased the combined effect of GATA3 with Ets1 and Ets2 in the presence of PMA. The data further demonstrate that, in addition to Ets1, Ets2 is also able to functionally cooperate with Tax1. The synergism of GATA3 with either Ets1 or Ets2 may play an important role in calcium- or Tax1-dependent regulation of IL-5 expression in Th2 cells or in HTLV-I transformed adult T-cell leukemia cells, respectively.
Physiological and performance responses to tournament wrestling.

PURPOSE The purpose of this study was to investigate the physiological and performance responses to a simulated freestyle wrestling tournament after typical weight loss techniques used by amateur wrestlers. METHODS Twelve Division I collegiate wrestlers (mean +/- SD;19.33 +/- 1.16 yr) lost 6% of total body weight during the week before a simulated, 2-d freestyle wrestling tournament. A battery of tests was performed at baseline and before and immediately after each individual match of the tournament. The test battery included assessment for body composition, reaction/movement time, lower and upper body power and isokinetic strength, and a venous blood sample. RESULTS Lower body power and upper body isometric strength were significantly reduced as the tournament progressed (P < or = 0.05). Significant elevations in testosterone, cortisol, and lactate were observed after each match (P < or = 0.05). However, there was a significant reduction (P < or = 0.05) in resting testosterone values in the later matches. Norepinephrine increased significantly (P < or = 0.05) after each match, whereas epinephrine increased significantly (P < or = 0.05) after each match except the last match of each day. Plasma osmolality was consistently higher than normal values at all times including baseline, with significant increases observed after each match (P < or = 0.05). CONCLUSIONS Tournament wrestling augments the physiological and performance decrements of weight loss and its impact is progressive over 2 d of competition. The combined effects of these stresses may ultimately be reflected in a wrestler's ability to maintain physical performance throughout a tournament.
Façade map: continuous interaction with media façades using cartographic map projections

The increasing number of media façades is a prominent example of the digital augmentation of urban spaces. Many media façades cover most of the outer shell of a building and come with a 3D form factor. They offer great potential for remote interaction in which the interactive area goes beyond the parts of the façade that are visible from the user's current perspective. Common interaction techniques often focus on a fixed part of the media façade. This restricts exploiting the full capabilities and the potential of such gigantic screens. In this paper we describe how to apply cartographic map projections to create 2D map representations of media façades to address this problem. We describe how a continuous interaction with the media façade is possible, independent of the form factor. We analyze existing media façades and provide a set of guidelines for how to create façade maps for different form factors.
Resolving conflict and inconsistency in norm-regulated virtual organizations

Norm-governed virtual organizations define, govern and facilitate coordinated resource sharing and problem solving in societies of agents. With an explicit account of norms, openness in virtual organizations can be achieved: new components, designed by various parties, can be seamlessly accommodated. We focus on virtual organizations realised as multiagent systems, in which human and software agents interact to achieve individual and global goals. However, any realistic account of norms should address their dynamic nature: norms will change as agents interact with each other and their environment. Due to the changing nature of norms or due to norms stemming from different virtual organizations, there will be situations when an action is simultaneously permitted and prohibited, that is, a conflict arises. Likewise, there will be situations when an action is both obliged and prohibited, that is, an inconsistency arises. We introduce an approach, based on first-order unification, to detect and resolve such conflicts and inconsistencies. In our proposed solution, we annotate a norm with the set of values their variables should not have in order to avoid a conflict or an inconsistency with another norm. Our approach neatly accommodates the domain-dependent interrelations among actions and the indirect conflicts/inconsistencies these may cause. More generally, we can capture a useful notion of inter-agent (and inter-role) delegation of actions and norms associated to them, and use it to address conflicts/inconsistencies caused by action delegation. We illustrate our approach with an e-Science example in which agents support Grid services.
