A semi-matching in a bipartite graph (Formula presented.) is a set of edges (Formula presented.) such that each vertex in U is incident to exactly one edge in M, i.e., (Formula presented.) for each (Formula presented.). An optimal semi-matching is a semi-matching with the minimal value of the cost function (Formula presented.). Exploiting the divide-and-conquer nature of the semi-matching problem, we reduce the problem to a simpler problem whose objective is to compute a maximum weak bounded-degree semi-matching. Using the reduction we derive three algorithms for the optimal semi-matching problem. The first one runs in time (Formula presented.) on a graph with n vertices and m edges. The second one is randomized and computes an optimal semi-matching with high probability in time (Formula presented.), where (Formula presented.) is the exponent of the best known matrix multiplication algorithm. Since (Formula presented.), this algorithm breaks through (Formula presented.) barrier for dense graphs. In the case of planar graphs, the third one computes an optimal semi-matching in deterministic time (Formula presented.). © 2016 Springer Science+Business Media New York

The k-path vertex cover of a graph G is a subset S of vertices of G such that every path on k vertices in G contains at least one vertex from S. Denote by ψk(G) the minimum cardinality of a k-path vertex cover set in G. The minimum k-path vertex cover problem (k-PVCP) is to find a k-path vertex cover of size ψk(G). In this paper we present an FPT algorithm to the 3-PVCP with runtime O(1.8172snO(1)) on a graph with n vertices. The algorithm constructs a 3-path vertex cover of size at most s in a given graph G, or reports that no such 3-path vertex cover exists in G. This improves previous O(2snO(1)) upper bound by Tu [5] and O(1.882snO(1)) upper bound by Wu [13]. © 2015 Elsevier B.V. All rights reserved.

Web search engines are designed to serve all users, independent of the special needs of any individual user. The objective of the project is to develop a personalized web search engine which considers users interest and generates search results based on the user's semantic profile. The proposed system utilizes clustering and re-ranking algorithms in order to organize the web documents and provide an order to the results displayed to the user. Web crawlers are utilized to get the links, images and allied information from the World Wide Web. The fetched documents are further clustered using suffix tree clustering algorithm, which enhances the performance of the web search engine. The results are organized using Page Re-Rank algorithm which considers hyperlink and link structure information to bring an order to the web. The system creates a semantic profile of the user by monitoring and analyzing the users search history. The search results generated will utilize an amalgamation of varied techniques including clustering, re-ranking and semantic user profiles to enhance the performance of the web search engine. © 2011 IEEE.

The introduction of new topical drugs based on new chemical entities has become a rare event. Instead, pharmaceutical companies have been focused on reformulating existing drugs resulting in an ever-growing number of topical drug products for every approved drug substance. In light of this trend, soon reformulations may not be as rewarding to their sponsors as they are today unless they offer a substantial improvement over other formulations of the same drug substance and the same indication, namely improved efficacy over existing drugs, reduced side effects, unique drug combinations, or applicability for new indications. This article reviews and compares topical drug delivery systems currently under active research that are designed to offer such advantages in the coming years. The reviewed delivery systems are: liposomes, niosomes, transferosomes, ethosomes, solid lipid nanoparticles, nanostructured lipid carriers, cyclodextrin, and sol-gel microcapsules. Among all the topical drug delivery systems currently undergoing active research, only the sol-gel microencapsulation is at clinical stages. © 2012 Wiley Periodicals, Inc.

This experiment studied the impact of various task phrasings on the search process. Eighty-eight searchers performed four web search tasks prescribed by the researchers. Each task was linked to an existing target web page, containing a piece of text that served as the basis for the task. A matching phrasing was a task whose wording matched the text of the target page. A nonmatching phrasing was synonymous with the matching phrasing, but had no match with the target page. Searchers received tasks for both types in English and in Hebrew. The search process was logged. The findings confirm that task phrasing shapes the search process and outcome, and also user satisfaction. Each search stage-retrieval of the target page, visiting the target page, and finding the target answer-was associated with different phenomena; for example, target page retrieval was negatively affected by persistence in search patterns (e.g., use of phrases), user-originated keywords, shorter queries, and omitting key keywords from the queries. Searchers were easily driven away from the top-ranked target pages by lower-ranked pages with title tags matching the queries. Some searchers created consistently longer queries than other searchers, regardless of the task length. Several consistent behavior patterns that characterized the Hebrew language were uncovered, including the use of keyword modifications (replacing infinitive forms with nouns), omitting prefixes and articles, and preferences for the common language. The success self-assessment also depended on whether the wording of the answer matched the task phrasing. © 2012 ASIS & T.

In the modern world, management of a disaster depends on the ability to respond fast and in an effective way at various levels, according to responsibilities and authority, mainly in co-ordination between the various organisations and officials. Dealing effectively with disasters begins long before it happens. During the disaster, it's too late - you cannot invest the necessary resources to deal with the disaster if you haven't made the necessary preparations. Therefore, high-end, state-of-the-art systems are required to manage and control crises and disasters. One of the most important components of such a system, if not the most important, is its mapping element and GIS capabilities.

Streptococcus pneumoniae (S. pneumoniae) is a major pathogen worldwide. The currently available polysaccharide-based vaccines significantly reduce morbidity and mortality. However, the inherent disadvantages of the currently available polysaccharide-based vaccines have motivated the search for other bacterial immunogens capable of eliciting a protective immune response against S. pneumoniae. Fructose-1,6-bisphosphate aldolase (FBA) is a glycolytic enzyme, which was found to localize to the bacterial surface, where it functions as an adhesin. Previously, immunizing mice with recombinant FBA (rFBA) in the presence of alum elicited a protective immune response against a lethal challenge with S. pneumoniae. Thus, the aim of the present study was to determine the cytokine responses that are indicative of protective immunity following immunization with rFBA. The protective effects against pneumococcal challenge in mice immunized with rFBA with complete Freunds adjuvant (CFA) in the initial immunization and with incomplete Freunds adjuvant (IFA) in booster immunizations surpassed the protective effects observed following immunization with either rFBA + alum or pVACfba. CD4+ T-cells obtained from the rFBA/CFA/IFA/IFA-immunized mice co-cultured with rFBA-pulsed antigen-presenting cells (APCs), exhibited a significantly greater proliferative ability than CD4+ T-cells obtained from the adjuvant-immunized mice co-cultured with rFBApulsed APCs. The levels of the Th1-type cytokines, interferon (IFN)-, interleukin (IL)-2, tumor necrosis factor (TNF)- and IL-12, the Th2-type cytokines, IL-4, IL-5 and IL-10, and the Th17-type cytokine, IL-17A, significantly increased within 72 h of the initiation of co-culture with CD4+ T-cells obtained from the rFBAimmunized mice, in comparison with the co-cultures with CD4+ T-cells obtained from the adjuvant-immunized mice. Immunizing mice with rFBA resulted in an IgG1/IgG2 ratio of 41, indicating a Th2 response with substantial Th1 involvement. In addition, rabbit and mouse anti-rFBA antisera significantly protected the mice against a lethal S. pneumoniae challenge in comparison with preimmune sera. Our results emphasize the mixed involvement of the Th1, Th2 and Th17 arms of the immune system in response to immunization with pneumococcal rFBA, a potential vaccine candidate.

Microsoft has launched a new web site to kick off a marketing campaign aimed at convincing users of Unix-based systems to switch to Microsoft server products, specifically those involving .NET technologies. The site begins with a picture of an oddly angry-looking clipart model, who presumably stands for the skeptical Unix software developer. The opening tagline is "we know we have only fifteen seconds to convince you why platforming your solution on Microsoft technology is a good business decision." Ignoring the fact that "platforming" is not a word, what does this mean? NXT is designed to make your migration easier and more cost-effective by giving you exclusive resources and benefits at each and every step to help ensure your transition to Microsoft is a success," the NXT Web site said. "We recognize changing or adding a platform is a big decision. "You need solid business reasons to back that decision and top-notch support to see it through." The site is aimed at Independent Software Vendors (ISVs) who create server-side programs. Already Microsoft has assembled a team of software companies to help out with the transition, including Aditi, ArtinSoft, ASNA, Augmentum, Aztec Software, Barry-Wehmiller International Resources, DTR Business Systems, Ness Technologies, NITI Technologies, Persistent, Sonata, and Symphony. Along with Microsoft, these companies will help out any ISV that wants to transition its Linux or Unix software to a Microsoft platform. The primary motivations Microsoft is using for the switch are: decreased development costs, decreased time-to-market, and increased revenue. Some of the arguments they use to bolster these claims are somewhat tenuous. For example, to support the "increased revenue" claim, they show a graph based on data from IDC showing total revenue for software deployed on Microsoft, Unix and Linux as US$91 billion, US$53 billion and US$4 billion respectively. However, this does not break sales down into market segments (such as desktop software and server software) and the fact that there is a larger market does not necessarily translate to increased revenue for a single software supplier. One final question remains: why "NXT"? The website is unclear whether NXT should be capitalized or left in lower case, but what does it mean? Is it just a pun on the word "next"? Should I be thinking about black, cubic, magnesium computers? Or is it trying to build on ".NET" by making it more eXtreme? Only the folks in marketing can say for sure.
