An Algorithm of Topic Distillation Based on Anchor Text

For topic distillation and topic exploration, a rich resource is the information from hyper linked Web pages. The anchor text, an objective summary of Web pages, is of strong topic and semantic indication. As to the triangular relationship of the hub Web page, anchor text, and authoritative Web page, a good hub Web page is the one that is directed to a good authoritative Web page through the authoritative anchor text; an authoritative anchor text is the one that connects good hub Web page and good authoritative Web page; and a good authoritative Web page is the one that a good hub Web page directs to through a good authoritative anchor text. This paper is mainly about hypertext-based topic analysis models and community-based topic distillation. Through comparative analysis, it can be concluded that the hypertext-based topic distillation contributes to improving the quality of topic distillation.
The Human Body Characteristics as a Signal Transmission Medium for Intrabody Communication

The human body characteristics as a signal transmission medium are studied for the application to intrabody communication. The measurements of the body channel cover the frequency range from 100 kHz to 150 MHz and the distance on the body up to 1.2 m. A distributed RC model is developed to analyze the large variation of the channel properties according to the frequency and channel length. The simulation results using the channel model match well with the measurements in both the frequency and time domains. The effect of the ground plane to the body channel transceivers is also investigated and an empirical formula for the minimum ground size is obtained. Finally, the amount of the electromagnetic radiation due to the body antenna effect is measured. With regards to the Federal Communications Commission regulations, the proper frequency range for the intrabody communication is determined to satisfy given bit error rate requirements
GURPR*: a new global software pipelining algorithm

Software pipclining as an effective loop optimization technique has been widefy used in various optimizing compilers. Afthough some software pipefining algorithms can optimize complicated loops globally, they are still not satisfied both in time efficiency and space efficiency simultaneously. In this paper, we present a new global software pipelining algorithm GURPR* which is applied in the URPR-1 optimtilng compiler. Preliminary experiments show that GURPR* has good time efficiency as well as good space efficiency which is quite important for a single-chip VLIW machine with limited capacity of onchip sxmtrol memory.
Continuing professional development in higher education: debating the academic perspective

This paper provides an overview of a research project in progress and the debates it addresses. The three-year project is set within the context of contemporary UK Higher Education (HE) policy. The paper summarises the research which focuses on developing an understanding of the influences on Continuing Professional Development (CPD) practices in academia, in particular exploring how academics interpret their responsibilities for their own lifelong learning and knowledge creation within the learning organisation. This paper provides an overview of the research context, before exploring relevant current debates and issues from the literature. In this way, the author raises some of the contemporary debates and dilemmas in relation to CPD in Higher Education; examples include: the intention and influence of national policy, including analysis of how higher education policy is interpreted, implemented and impacts upon practice; how CPD is defined and understood; collectivity and social learning in academia; and the motivations, intentions and actions of academics in respect of CPD. In the light of the discussion, the research project’s overall purpose, aims, rationale and key questions are detailed. The conceptual and theoretical framework that underpins this work is taken from ‘third generation activity theory’, its principles and assumptions are also elaborated within this paper. The paper therefore raises debates and apparent tensions and dilemmas related to CPD in academia. In view of those debates, the qualitative multi-case study project outlined in the paper, which has a distinct and original focus on the perspective and ‘voices’ of academics, is likely to result in outcomes that are important and significant for a range of stakeholders across the higher education sector.
Choroidal Thickness Values Following the Consumption of Sildenafil and Tadalafil: Comparison of the OCT Records

Objective: The aim of this study is to demonstrate the anatomic and physiologic changes in the choroid following systemic sildenafil and tadalafil. Methods: This cross-sectional randomized study enlisted 20 young and healthy men, who were randomly and equally classified in two groups; group a received 50 mg of Sildenafil, whereas group B received 10 mg of Tadalafil. All participants underwent a measurement of choroidal thickness, based on enhanced depth imaging optical coherence tomography (EDI-OCT). The measurement was repeated two hours after the consumption of each PDE-5 inhibitor. Results: The mean age of participants was 34.2 ± 3.0 and 34.6 ± 3.2 years in group A and B, respectively. The mean values of choroidal thickness (CT) in Group A at baseline were 306.6 ± 11.1 μm, 229.9 ± 12.7 μm and 311.3 ± 21.8 μm in temporal, nasal and inferior quadrants, respectively. The mean increase in choroidal thickness in Group A two hours after receiving sildenafil was 29.9 μm, 23.8 μm and 34.2 μm in temporal (CI [-35.18,-24.62], p<0.001), nasal (CI [-27.20,-20.40], p<0.001) and inferior (p=0.005) quadrants, respectively. On the other hand, the mean values of choroidal thickness in Group B at baseline were 307.2 ± 10.6 μm, 227.4 ± 8.9 μm and 315.8 ± 9.1 μm in temporal, nasal and inferior quadrants, respectively. Significant raise was also noted in Group B two hours after tadalafil intake in temporal (13.2 μm, CI [-17.77,-8.63], p<0.001), nasal (12.7 μm, CI [-14.75,-10.65], p<0.001) and inferior (15.6 μm, CI [-17.36,-13.84], p<0.001) quadrants, respectively. The increment in choroidal thickness observed after the intake of PDE-5 inhibitors was greater in group A and this difference exhibited statistical significance (independent samples t-test, CT temporal: t(18)=5.338, p<0.001, 95%CI [9.95, 22.85], Levene's test: p=0.791, CT nasal: t(18)=6.332, p<0.001, 95%CI [7.48, 14.92], Levene's test: p=0.088, Mann-Whitney test, CT inferior: p<0.001). Conclusion: Both sildenafil and tadalafil resulted in the increment of choroidal thickness, but tadalafil caused a lower increase. This alteration could secondary affect retinal function or be a useful adjunct whenever increase choroidal blood flow is demanded.
A novel architecture for a blog crawler

A general crawler downloads web pages that may be of any kind, thus forming a source of information for the search engine. Blog crawler is similar to a general crawler except that it restricts its crawl boundary to the blog space, thus downloading only the blog pages and ignoring rest of the web. Since blog is an emerging phenomenon and serve as very useful source of information, a blog crawler proves to be of great help in this regard. We propose a new algorithm for blog crawler and discuss a number of related issues. Also, as the result of analysis, it has been found that our proposed blog crawler is superior to the general crawler.
Send Orders of Reprints at Reprints@benthamscience.net Cultivar and Growing Location Effects on Fatty Acids, Minerals, and Sugars in Green Seeds of White Lupin (lupinus Albus L.)

Evaluation of green immature seeds from ten cultivars of white lupin (Lupinus albus L., Fabaceae), grown in two locations in Virginia (USA) during two years, indicated that physiological mature but green white lupin seeds contained 33 percent protein and 7 oil on dry weight basis. Contents of C18:3, saturated, unsaturated, mono-unsaturated, and poly-unsaturated fatty acids in white lupin green seeds were 10, 18, 84, 40, and 42 percent of total oil, respectively. White lupin green seeds contained 0. Growing locations significantly affected composition of green white lupin seeds whereas effects of cultivars were limited. White lupin green seeds compared well with green peas and vegetable soybean seeds. Results indicated that white lupin green seeds may have potential as human food. INTRODUCTION Mature white lupin (Lupinus albus L., Fabaceae) seeds have been used as food for over 3000 years around the Medi-terranean and for as much as 6,000 years in the Andean highlands. White lupin, a cool-season legume plant native to the Mediterranean, North Africa, and North and South America, has been evaluated as a grain, forage, and green manure crop in Virginia and the mid-Atlantic region of the United States. Extensive research has resulted in development of winter-hardy lines and a production system [1-6]. Additional research has laid the foundation for utilization of white lupin mature seeds as food [7]. Mature white lupin seeds produced in Virginia contain 32 to 43 % protein with a mean of 37 %, 3 to 7 % oil with a mean of 5%, and 5 to 9 % sugar with a mean of 7% [2].
Cross–regulatory interactions between Fgf8 and Shh in the avian frontonasal prominence

ABSTRACT The frontonasal prominence of the developing avian embryo contains an organizing center, defined by juxtaposition of the Sonic hedgehog (Shh) and Fibroblast growth factor 8 (Fgf8) expression domains. This molecular interface presages any detectable growth of the frontonasal prominence, and experiments involving transplantation of this boundary epithelium have demonstrated it is a source of dorsal‐ventral and rostral‐caudal patterning information for the neural crest‐derived mesenchyme of the upper beak. We explored the ontogeny of this organizing center by mapping the expression domains of both genes and their receptors and downstream targets. We tested the extent to which Shh and Fgf8 regulate each other's expression in this frontonasal organizer by either blocking or ectopically activating these pathways. Our experiments revealed mutual antagonism between the two molecules, which aids in establishing and maintaining a molecular boundary that subsequently influences patterning and growth of the middle and upper face.
Axl, A Receptor Tyrosine Kinase, Mediates Flow-Induced Vascular Remodeling

Intima-media thickening (IMT) in response to hemodynamic stress is a physiological process that requires coordinated signaling among endothelial, inflammatory, and vascular smooth muscle cells (VSMC). Axl, a receptor tyrosine kinase, whose ligand is Gas6, is highly induced in VSMC after carotid injury. Because Axl regulates cell migration, phagocytosis and apoptosis, we hypothesized that Axl would play a role in IMT. Vascular remodeling in mice deficient in Axl (Axl−/−) and wild-type littermates (Axl+/+) was induced by ligation of the left carotid artery (LCA) branches maintaining flow via the left occipital artery. Both genotypes had similar baseline hemodynamic parameters and carotid artery structure. Partial ligation altered blood flow equally in both genotypes: increased by 60% in the right carotid artery (RCA) and decreased by 80% in the LCA. There were no significant differences in RCA remodeling between genotypes. However, in the LCA Axl−/− developed significantly smaller intima+media compared with Axl+/+ (31±4 versus 42±6×10−6 &mgr;m3, respectively). Quantitative immunohistochemistry of Axl−/− LCA showed increased apoptosis compared with Axl+/+ (5-fold). As expected, p-Akt was decreased in Axl−/−, whereas there was no difference in Gas6 expression. Cell composition also changed significantly, with increases in CD45+ cells and decreases in VSMC, macrophages, and neutrophils in Axl−/− compared with Axl+/+. These data demonstrate an important role for Axl in flow-dependent remodeling by regulating vascular apoptosis and vascular inflammation.
Teachers as Leaders: Is the Principal Really Needed?.

This paper addresses educational reform centering on teacher participation and leadership. Although schools have developed new mission statements and implemented strategic planning and site-based management in recent years, most schools are not set up to accept teachers in leadership roles. The literature suggests that our "new" schools must be built on shared authority and responsibility, which requires that staff trade assignments and work in multiple groups to remain in touch with the school as a whole. In 1990, Woods Learning Center (WLC)--an elementary school in Casper, Wyoming--eliminated the position of school principal. Driving this decision was the desire to reallocate the money saved in a principal's salary to the children in the classroom. At WLC, principal duties and responsibilities are shared across the whole staff in the form of administrative teams--pairs of teachers responsible for handling such matters as budget and finance, board and community relations, curriculum and instruction, staff evaluation, and staff hiring. In interviews, board members commented that a traditional principal would have inhibited or prevented this change. Although research regarding shared decision making and the role of teachers as leaders is not promising, this school has experienced success with the changes it has made. Most teachers have had little preparation in school governance. Until leadership skills and competencies are addressed in teacher education programs, attempts to improve schools through changes in governance structures will continue to have little effect.

Means and Requirements for a Roadmap to Promote Fuzzy Technology in Medical Image Processing

Some features are collected get an instruction plan or roadmap to spread the fuzzy methodology in the medical communication Fuzzy methods should be arranged according to the hierarchy of medical image processing procedures to allow a convenient comparison with competitive crisp methods. Structure and function of linguistic variables are explained in some detail because of their peculiar ability to cope with uncertainties. The difference between a probabilistic and a possibilistic solution of a problem in image processing is dealt with in view of the unjustified predominance of probabilistic thinking in medicine
CARS: Context-Aware Rate Selection for vehicular networks

Traffic querying, road sensing and mobile content delivery are emerging application domains for vehicular networks whose performance depends on the throughput these networks can sustain. Rate adaptation is one of the key mechanisms at the link layer that determine this performance. Rate adaptation in vehicular networks faces the following key challenges: (1) due to the rapid variations of the link quality caused by fading and mobility at vehicular speeds, the transmission rate must adapt fast in order to be effective, (2) during infrequent and bursty transmission, the rate adaptation scheme must be able to estimate the link quality with few or no packets transmitted in the estimation window, (3) the rate adaptation scheme must distinguish losses due to environment from those due to hidden-station induced collision. Our extensive outdoor experiments show that the existing rate adaptation schemes for 802.11 wireless networks under utilize the link capacity in vehicular environments. In this paper, we design, implement and evaluate CARS, a novel context-aware rate selection algorithm that makes use of context information (e.g. vehicle speed and distance from neighbor) to systematically address the above challenges, while maximizing the link throughput. Our experimental evaluation in real outdoor vehicular environments with different mobility scenarios shows that CARS adapts to changing link conditions at high vehicular speeds faster than existing rate-adaptation algorithms. Our scheme achieves significantly higher throughput, up to 79%, in all the tested scenarios, and is robust to packet loss due to collisions, improving the throughput by up to 256% in the presence of hidden stations.
A new enhanced technique for link farm detection

Search engine spam is a webpage that has been designed to artificially inflating its search engine ranking. Recently this search engine spam has been increased dramatically and creates problem to the search engine and the web surfer. It degrades the search engine's results, occupies more memory and consumes more time for creating indexes, and frustrates the user by giving irrelevant results. Search engines have tried many techniques to filter out these spam pages before they can appear on the query results page. Spammers intend to increase the PageRank of certain spam pages by creating a large number of links pointing to them. We have designed and develop a system, spamcity score that detects spam hosts or pages on the Web. The UK Web Spam UK 2007 data set has been used for experimentation. It is a public web spam dataset annotated at the level of hosts, for all results reported here. System uses the key features of popular link based algorithms to detect spam in improved manner. In this paper, various ways of creating spam pages, a collection of current methods that are being used to detect spam and a new approach to build a tool for improving link spam detection using spamcity score of term spam. This new approach uses SVMLight tool to detect the link spam which considers the link structure of Web and page contents. These statistical features are used to build a classifier that is tested over a large collection of Web link spam. The link farm can be identifying based on Web Graph, classification by using SVMLight Tool, Degree based measure, page Rank, Trust Rank, and Truncated PageRank. The spam classifier makes use of the Wordnet word database and SVMLight tool to classify web links as either spam or not spam. These features are not only related to quantitative data extracted from the Web pages, but also to qualitative properties, mainly of the page links.
A regional cell routing in wireless sensor networks

Among routing protocols of wireless sensor networks, hierarchical routing protocols are more efficient, in general, because they involve less sensor nodes for data transmission. However, when events happen regionally and dynamically, unnecessary overheads occur in hierarchical routing protocols. In this paper, we propose a regional cell routing protocol to overcome the overheads of conventional hierarchical routing protocols: The protocol organizes cells with sensor nodes which have sensed similar events and it selects representative nodes in the cells. The representative nodes collects data in the cells and then the nodes compress data and deliver them to the sink node. Our simulation results show that the proposed routing protocol has improved its performance in terms of energy and latency by comparing with other routing protocols of wireless sensor networks.
DOM: A big data analytics framework for mining Thai public opinions

This paper presents the development of DOM, a mobile big data analytics engine for mining Thai public opinions. The engine takes in data from multiple well-known social network sources, and then processes them using MapReduce, a keyword-based sentiment analysis technique, and an influencer analysis algorithm to determine public opinions and sentiments of certain topics. The system was evaluated its sentiment prediction accuracy by matching the predicted result with the human sentiment and tested on various case studies. The effectiveness of the approach demonstrates the practical applications of the engine.

1 Let there be given n points in the plane. Denote by t i the number of lines which contain exactly i of the points (2 < i < n). The properties of the set {ti } have been studied a great deal. For example, there is the classical result of Gallai and Sylvester : Assume to = 0 (i .e ., the points are not all on one line) ; then t2 > 0. For the history of this problem see, e.g . , Motzkin [6] and Erdős [3, 4]. 1n this note we prove that some new and perhaps unexpected properties of the family {ti } hold. Let there be given n distinct points in the plane, not all on a line. We conjectured that for n > n o there always is an i such that t i > n-1. Krier and Straus pointed out that for n = 6 and 9 there are counterexamples. For n = 9, take the vertices of a square and its center and the four points of infinity determined by the sides and diagonals of the square. For n = 13 we also get a counterexample from the vertices of a regular hexagon and its center and the six points of infinity determined by the sides and diagonals of the hexagon. Nevertheless, the conjecture is true for n , 25. In fact we show in Theorem 1 that we can always choose i = 2 or 3, and that max ti = max(t2 , t 3). i Assume now that no line has more than (1-e)q points on it. Then we are convinced that there is an 7) = 7)(e) such that
Algorithms for Maximum Satisfiability using Unsatisfiable Cores

Many decision and optimization problems in electronic design automation (EDA) can be solved with Boolean satisfiability (SAT). Moreover, well-known extensions of SAT also find application in EDA, including pseudo-Boolean optimization, quantified Boolean formulas, multi-valued SAT and, more recently, Maximum Satisfiability (MaxSAT). Algorithms for MaxSAT are still fairly inefficient in industrial settings, in part because the most effective SAT techniques cannot be easily extended to MaxSAT. This paper proposes a novel algorithm for MaxSAT that improves existing state of the art solvers by orders of magnitude on industrial benchmarks. The new algorithm exploits modern SAT solvers, being based on the identification of unsatisfiable subformulas. Moreover, the new algorithm provides additional insights between unsatisfiable subformulas and the maximum satisfiability problem.
