Social network extraction based on web: 2. Strategies in superficial methods

Different superficial methods for extracting social network from Web have common approach, but also developed based on different strategies. This difference is due to the characteristics of the source of information that is the source of the social network. There is a hit count, URL address and snippet as a result of any search engine restore, it can efficiently be used to extract social networks with the right strategy. This paper describes some of the results based on the strategies that have been developed.

The SpacePix-D radiation monitor technology demonstrator

We present the SpacePix-D, a battery-operated standalone pixel detector with built-in LCD for real-time visualization of particle hits and Bluetooth for wireless access. The SpacePix-D allows the possibility of local and remote operation and it serves as a demonstrator for the new 180 nm SoI monolithic 64 × 64 pixel detection ASICs with hit counting and deposited energy measurement capability. Currently, it operates with the X-chip03 detection ASIC which can be upgraded to a new class of SpacePix pixel detectors. The SpacePix ASIC has been submitted for manufacturing and it was designed for charged particle sensing in the space environment. It features a logarithmic front-end amplifier response to cover a large required dynamic range for heavy ion detection and SEU-hardened digital circuits.

Range smart cluster monitor based guesstimate approach for resource scheduling in small size clusters

Performing scheduling of tasks with low energy consumption with high performance is one of the major concerns in distributed computing. Most of the existing systems have achieved improved energy efficiency but compromised with QoS metrics such as makespan and resource utilization. A resource scheduling strategy for wireless clusters is proposed by making careful considerations on decisions that would im-prove the battery life of nodes. The proposed strategy also incorporates monitoring system with in the clusters for optimizing the system performance as well as energy consumption. The system ensures “Any case zero loss" performance wherein each cluster will be monitored by at least one cluster monitor. This is implemented by using predictive calculation at each cluster monitor to communicate only if absolutely essential, during assigning jobs to resources, selecting optimal resources by assigning the jobs to the most power efficient resource among the available idle resources within the cluster. The experimental result ensures improved system performance with low power consumption in homogeneous computing environment. The resource sharing strategy is experimentally analyzed, considering the important performance metrics such as starvation deadline, turnaround time, miss hit count through simulations. Significant results were observed with improved efficiency.

Hit count estimate variability for website-specific queries in search engines

PurposeThe purpose of this paper is to determine the effect of the chosen search engine results page (SERP) on the website-specific hit count estimation indicator.Design/methodology/approachA sample of 100 Spanish rare disease association websites is analysed, obtaining the website-specific hit count estimation for the first and last SERPs in two search engines (Google and Bing) at two different periods in time (2016 and 2017).FindingsIt has been empirically demonstrated that there are differences between the number of hits returned on the first and last SERP in both Google and Bing. These differences are significant when they exceed a threshold value on the first SERP.Research limitations/implicationsFuture studies considering other samples, more SERPs and generating different queries other than website page count (<site>) would be desirable to draw more general conclusions on the nature of quantitative data provided by general search engines.Practical implicationsSelecting a wrong SERP to calculate some metrics (in this case, website-specific hit count estimation) might provide misleading results, comparisons and performance rankings. The empirical data suggest that the first SERP captures the differences between websites better because it has a greater discriminating power and is more appropriate for webometric longitudinal studies.Social implicationsThe findings allow improving future quantitative webometric analyses based on website-specific hit count estimation metrics in general search engines.Originality/valueThe website-specific hit count estimation variability between SERPs has been empirically analysed, considering two different search engines (Google and Bing), a set of 100 websites focussed on a similar market (Spanish rare diseases associations), and two annual samples, making this study the most exhaustive on this issue to date.

Social network extraction based on Web: 3. the integrated superficial method

The Web as a source of information has become part of the social behavior information. Although, by involving only the limitation of information disclosed by search engines in the form of: hit counts, snippets, and URL addresses of web pages, the integrated extraction method produces a social network not only trusted but enriched. Unintegrated extraction methods may produce social networks without explanation, resulting in poor supplemental information, or resulting in a social network of durmise laden, consequently unrepresentative social structures. The integrated superficial method in addition to generating the core social network, also generates an expanded network so as to reach the scope of relation clues, or number of edges computationally almost similar to n(n − 1)/2 for n social actors.

Cache Replacement Policy Based on Expected Hit Count

Memory-intensive workloads operate on massive amounts of data that cannot be captured by last-level caches (LLCs) of modern processors. Consequently, processors encounter frequent off-chip misses, and hence, lose significant performance potential. One of the components of a modern processor that has a prominent influence on the off-chip miss traffic is LLC's replacement policy. Existing processors employ a variation of least recently used (LRU) policy to determine the victim for replacement. Unfortunately, there is a large gap between what LRU offers and that of Belady's MIN, which is the optimal replacement policy. Belady's MIN requires selecting a victim with the longest reuse distance, and hence, is unfeasible due to the need for knowing the future. In this work, we observe that there exists a strong correlation between the expected number of hits of a cache block and the reciprocal of its reuse distance. Taking advantage of this observation, we improve the efficiency of last-level caches through a low-cost-yet-effective replacement policy. We suggest a hit-count based victim-selection procedure on top of existing low-cost replacement policies to significantly improve the quality of victim selection in last-level caches without commensurate area overhead. Our proposal offers 12.2 percent performance improvement over the baseline LRU in a multi-core processor and outperforms EVA, which is the state-of-the-art replacement policy.

Survey and evaluation of web search engine hit counts as research tools in computational linguistics

In recent years, many studies on computational linguistics have employed the Web as source for research. Specifically, the distribution of textual data in the Web is used to drive linguistic analyses in tasks such as information extraction, knowledge acquisition or natural language processing. For these purposes, commercial Web search engines are commonly used as the low-entry-cost way to access Web data and, more specifically, to estimate the distribution of the entity(ies) of interest from the hit count the search engines provide when querying such entities. Even though several studies have evaluated the effectiveness of Web search engines as information retrieval tools from the perspective of the end users, few authors have assessed the suitability of hit counts as research tools in computational linguistics; moreover, studies so far have focused on the most well-known search engines (typically Google, Bing and Yahoo!), and neglected potentially interesting alternatives that have recently surfaced. To fill this gap, in this work, we first compile and survey the general-purpose search engines that are currently available. Then, we evaluate the suitability of the hit counts they provide under several perspectives that are relevant for computational linguistics: flexibility of the query language, linguistic coherence, mathematical coherence and temporal consistency. The results of our survey show that, even though the choice of a particular search engine has been generally ignored by researchers relying on Web data, there are significant quality differences between the hit counts of current search engines, and that the most well-known and widely-used search engines do not provide the best results. In this respect, we also identify the search engines whose hit counts are best suited for research.

Three Dimensional Velocity Structure of the Koyna-Warna Region using Local Earthquake Tomography

ABSTRACT A dense seismic network (∼100 stations) was operated in the Koyna-Warna region from January 2010 to May 2010, that allow us to collect 400 high-quality local earthquake data of magnitude less than 4. In this region, the fault structure and tectonic setting that accommodate the induced seismicity is not well understood. To investigate the seismotectonics of the region, we have inverted 7826 P- and 7047 S-P arrival times for 3-D Vp and Vp/Vs tomographic models along with hypocenters parameters in the region. Although, Dixit et al. (2014) have performed 3-D local earthquake tomography with double-difference tomography code using catalog differential time data. In this paper, Simulps14 code on the same data set is applied. For better approach P arrival time and S-P travel times are inverted directly for Vp, Vp/Vs variations and earthquake locations. High Vp ∼5.9 to 6.5 and low to high Vp/Vs ∼1.69-1.74 imaged in the hypocenter region. These features interpreted as a fluid bearing rock mass under high pore pressure. It is also observed that below the trap basement form a local topography depression between the Koyna and Warna Reservoirs. To the South of the Warna reservoir, intense seismic activity defines a major cluster of ∼ 5 km width at 3 to7 km deep, located under the trap, where the basement is deepening. Such regions are inferred to be associated with the seismically active faults zones. The obtain velocity anomalies are reliable down to a depth of 10 km. This is also confirmed by the analysis of three resolution parameters viz. Hit count, Derivative Weight sum (DWS) and Resolution Diagonal Elements (RDE).

NVM Way Allocation Scheme to Reduce NVM Writes for Hybrid Cache Architecture in Chip-Multiprocessors

Hybrid cache architectures (HCAs) containing both SRAM and non-volatile memory (NVM) have been proposed to overcome the disadvantages of NVM-based cache architecture. Most previous works have concentrated on managing write-intensive blocks by storing these blocks to SRAM to reduce the number of the write operations to NVM. However, they have not focused on reducing linefill operations which also occupy a large portion of overall NVM write counts in chip-multiprocessor (CMP) environments. This paper proposes an NVM way allocation scheme, taking into account the NVM linefill counts as well as cache miss rate and the NVM write hit counts during victim selection. Three metrics are introduced to estimate the effectiveness of NVM way allocation: Miss counts change (ΔM), write counts change (ΔW), and NVM write counts change (ΔNVMW). An algorithm to minimize the write counts of NVM based on these metrics is proposed as well. Our experimental results show that dynamic energy consumption is reduced by 37.5 percent on average.

09.11: Acoustic emission signal characteristics of damage accumulation in non‐buckling steel plate shear wall

ABSTRACTThis paper deals with acoustic emission (AE) monitoring of non‐buckling steel plate shear walls, in order to estimate damage accumulation of steel plate walls under cyclic loading. When material or any internal element in steel members develops plasticity or crack begins to form and grow rapidly, a large amount of energy will be released quickly within a short period. This would produce a series of transient stress waves, which is called AE signals. AE signals of the overall process contain useful information of irreversible accumulated damage in structural fatigue fracture progression. Continuous monitoring of low cycle fatigue plastic damage accumulation in steel plate walls is demonstrated in a corrugated‐shape steel plate wall under cyclic loading. Using the laboratory test data, the relationship between AE signals and fatigue damage accumulation in steel plate walls have been studied. It is revealed that the AE hit counts and energy can be used as one of the reference standards for judging the degree of plastic damage accumulation of material. AE damage accumulation evaluation based on AE hit and AE energy is a promising method for damage evaluation of steel hysteretic damping member. Compared with other conventional damage evaluation methods, it provides a new nondestructive testing approach to quantify the plastic damage of material, and it can be used to evaluate the member condition that are difficult to access.

Lithospheric structure of Southeast Anatolia from joint inversion of local and teleseismic data

A joint tomographic inversion of local and teleseismic arrival times recorded at 41 seismic stations in southeast Anatolia is conducted to study the 3-D lithospheric velocity structure and its relation to the prevailing tectonic processes. A total of 21300 arrivals from local and teleseismic events are used in the final inversion. The tomographic model reveals prominent lower crustal/uppermost mantle low-velocity anomalies. High-velocity zones are imaged in the western part of the study area. The background seismic activity occurs mainly at the low-velocity areas and to a lesser extent in some high-velocity zones. Large crustal earthquakes occur in average velocity zones, but not in high-velocity areas that can resist stress. Results of the checkerboard resolution test indicate the reliability of the obtained images; while the large hit counts at most depth slices denote reasonable ray-path coverage for most parts of the study area. The obtained velocity anomalies are generally consistent with many previous geophysical measurements and give much deeper understanding of the current seismotectonic processes occurring in the region.

Immobilization and high platelet count are associated with thromboembolic complications in heparin-induced thrombocytopenia.

Immune-mediated heparin-induced thrombocytopenia (HIT type II, HIT) is a potentially serious adverse drug reaction characterized by an increased risk of venous and arterial thrombosis. This study aimed to identify risk factors associated with the development of these complications. Our study cohort included patients with HIT assembled in our pharmacovigilance center by reports from 51 collaborating hospitals in Berlin, Germany. To identify risk factors for thromboembolic complications, patients with thromboembolic events (cases) were compared to those without thromboembolic events (controls) in a case-control design. We applied univariable and multivariable logistic regression analysis to estimate odds ratios (OR) and corresponding 95% confidence intervals (CI) for potential risk factors of thromboembolic complications. Our cohort comprised 209 HIT patients. Of those, 53 developed thromboembolic complications. Most HIT patients received heparin for medical indications (42.1%) or in the context of cardiovascular surgery (40.2%). Of the 78 thromboembolic complications, 49 (63%) and 29 (37%) were observed in the venous and arterial vascular bed, respectively. The main locations were deep vein thrombosis (39.7%), pulmonary embolism (16.7%), and limb artery thrombosis (16.7%). In multivariable analysis, immobilization prior to HIT (OR 4.6, 95% CI 1.2-18.0; P=.026) and higher platelet counts before initiation of heparin therapy (OR 1.004, 95% CI 1.000-1.008; P=.046) were independently associated with the occurrence of thromboembolic events. Immobilization and a high platelet count (with a low effect size) are additional risk factors of thromboembolic complications in the course of HIT.

Mixed mode fracture properties of GFRP-adhesive interfaces based on video gauge and acoustic emission measurements from specimens with adherend fibres normal to the interfaces

Mixed-mode bending tests were performed on fifty-three GFRP-adhesive-GFRP specimens. In each specimen the pre-crack was located near the GFRP adherend with fibres normal to the GFRP-adhesive interface, so as to encourage crack propagation along this interface rather than through the GFRP. The other GFRP adherend contained fibres parallel to the interface, leading to asymmetry of GFRP material (but not of specimen geometry) with respect to the adhesive layer in each specimen. This switching, across the adhesive layer, between normal and parallel fibres in the adherends, reflects a T-joint detail considered for a wave energy device. All tests used a video gauge system to measure crack propagation. Some tests also employed an acoustic emission (AE) system. Comparisons between the AE results and the video gauge-based crack propagation data strongly suggest that the AE energy vs time curve is a much clearer indication of crack initiation than is the widely used AE hit count vs time curve. Increase in Mode II ratio during the tests led to fewer but larger post-peak load drops. Williams's approach, based on beam theory for asymmetric sections with correction factors for large displacements and shear deformation included, led to fracture toughness (G(c)) values in the range 0.3-2.8 kJ/m(2), with a trend of increasing Gc values as pure Mode II is approached. The ASTM approach, developed only for symmetric specimens, gave much lower Gc values. (C) 2017 Elsevier Ltd. All rights reserved.

Web citations in patents: Evidence of technological impact?

Patents sometimes cite webpages either as general background to the problem being addressed or to identify prior publications that limit the scope of the patent granted. Counts of the number of patents citing an organization's website may therefore provide an indicator of its technological capacity or relevance. This article introduces methods to extract URL citations from patents and evaluates the usefulness of counts of patent web citations as a technology indicator. An analysis of patents citing 200 US universities or 177 UK universities found computer science and engineering departments to be frequently cited, as well as research‐related webpages, such as Wikipedia, YouTube, or the Internet Archive. Overall, however, patent URL citations seem to be frequent enough to be useful for ranking major US and the top few UK universities if popular hosted subdomains are filtered out, but the hit count estimates on the first search engine results page should not be relied upon for accuracy.

Website Quality Evaluation Based on Search Engine Queries using Web Rank Position Algorithm (WRPA)

&lt;p&gt;The research work is about to test the quality of the website and to improve the quality by analyzing the hit counts, impressions, clicks, count through rates and average positions. This is accomplished using WRPA and SEO technique. The quality of the website mainly lies on the keywords which are present in it. The keywords can be of a search query which is typed by the users in the search engines and based on these keywords, the websites are displayed in the search results. This research work concentrates on bringing the particular websites to the first of the search result in the search engine. The website chosen for research is SRKV. The research work is carried out by creating an index array of Meta tags. This array will hold all the Meta tags. All the search keywords for the website from the users are stored in another array. The index array is matched and compared with the search keywords array. From this, hit to count is calculated for the analysis. Now the calculated hit count and the searched keywords will be analyzed to improve the performance of the website. The matched special keywords from the above comparison are included in the Meta tag to improve the performance of the website. Again all the Meta tags and newly specified keywords in the index array are matched with the SEO keywords. If this matches, then the matched keyword will be stored for improving the quality of the website. Metrics such as impressions, clicks, CTR, average positions are also measured along with the hit counts. The research is carried out under different types of browsers and different types of platforms. Queries about the website from different countries are also measured. In conclusion, if the number of the clicks for the website is more than the average number of clicks, then the quality of the website is good. This research helps in improvising the keywords using WRPA and SEO and thereby improves the quality of the website easily.&lt;/p&gt;

Effects of grip span in one-handed thumb interaction with a smartphone

The purpose of this study was to investigate whether different grip spans affected the touch performance of one-handed thumb interaction with a smartphone. Tapping time, hit count, and thumb-tip displacement were measured while using three mock-ups of an iPhone 5S, 6, and 6 Plus, respectively. In the tapping task, four positions were tested: top-left, top-right, bottom-left, and bottom-right. The results showed that the hit count ( F2,14=8.596, p=.004) and thumb-tip displacement ( F2,14=11.348, p=.001) significantly decreased as the grip span increased. Thus, we concluded that there existed another problem beyond the limit of thumb length that caused a reachability issue when using a large smartphone. Thus, this should be considered in the user interface design of a large smartphone.

Metagenomic evidence for the presence of phototrophic Gemmatimonadetes bacteria in diverse environments

Gemmatimonadetes represents a poorly understood bacterial phylum with only a handful of cultured species. Recently, one of its few representatives, Gemmatimonas phototrophica, was found to contain purple bacterial photosynthetic reaction centres. However, almost nothing is known about the environmental distribution of phototrophic Gemmatimonadetes bacteria. To fill this gap, we took advantage of fast-growing public metagenomic databases and performed an extensive survey of metagenomes deposited into the NCBI's WGS database, the JGI's IMG webserver and the MG-RAST webserver. By employing Mg protoporphyrin IX monomethyl ester oxidative cyclase (AcsF) as a marker gene, we identified 291 AcsF fragments (24-361 amino acids long) that are closely related to G. phototrophica from 161 metagenomes originating from various habitats, including air, river waters/sediment, estuarine waters, lake waters, biofilms, plant surfaces, intertidal sediment, soils, springs and wastewater treatment plants, but none from marine waters or sediment. Based on AcsF hit counts, phototrophic Gemmatimonadetes bacteria make up 0.4-11.9% of whole phototrophic microbial communities in these habitats. Unexpectedly, an almost complete 37.9 kb long photosynthesis gene cluster with identical gene composition and arrangement to those in G. phototrophica was reconstructed from the Odense wastewater metagenome, only differing in a 7.2 kb long non-photosynthesis-gene insert. These data suggest that phototrophic Gemmatimonadetes bacteria are much more widely distributed in the environment and exhibit a higher genetic diversity than previously thought.

Evaluating the Suitability of Web Search Engines as Proxies for Knowledge Discovery from the Web

Many researchers use the Web search engines’ hit count as an estimator of the Web information distribution in a variety of knowledge-based (linguistic) tasks. Even though many studies have been conducted on the retrieval effectiveness of Web search engines for Web users, few of them have evaluated them as research tools. In this study we analyse the currently available search engines and evaluate the suitability and accuracy of the hit counts they provide as estimators of the frequency/probability of textual entities. From the results of this study, we identify the search engines best suited to be used in linguistic research.

Reading Function and Content Words in Subtitled Videos.

In this study, we examined how function and content words are read in intra- and interlingual subtitles. We monitored eye movements of a group of 39 deaf, 27 hard of hearing, and 56 hearing Polish participants while they viewed English and Polish videos with Polish subtitles. We found that function words and short content words received less visual attention than longer content words, which was reflected in shorter dwell time, lower number of fixations, shorter first fixation duration, and lower subject hit count. Deaf participants dwelled significantly longer on function words than other participants, which may be an indication of their difficulty in processing this type of words. The findings are discussed in the context of classical reading research and applied research on subtitling.

Publicize or Perish! A Guide to Social Media Promotion of Scientific Articles: Featuring the Plastic and Reconstructive Surgery "Author Tool Kit".

Sir: A recent blog examining promotion of scientific publications in the mainstream press concluded that academia has become part of the problem in generating biased interpretations of those studies.1 In contrast, we suggest that close collaboration between authors and public relations teams of scientific publications may ensure the accuracy of news items. There are incentives to authors to promote their scientific work: scientists compete for increasingly scarce grants; expanding journal numbers leads to dilution of scientific data. Authors need to keep their work afloat in this torrent of information. It is easy to see how exaggerated claims arise. First, authors may exaggerate the implications of their findings: we agree with the British Medical Journal’s proposal of accountability by having named authors on press releases.2 Second, distortion may arise during creation of press releases by marketing teams. Third, journalists may accept assertions in press releases without checking original studies. The Plastic and Reconstructive Surgery “Author Tool Kit” advises authors as to how a social media response can help build traffic for an article, ensuring that work will be read, spread, and cited beyond the confines of libraries and journal Web sites.3 It also provides information on making articles discoverable by search engine optimization, use of e-mail, and contacting press outlets. It is easier for authors to learn about social media than it is for commercial marketing companies to learn about scientific method. As a starting point, authors need a clear interesting message with widespread public relevance. Twitter has been central to disseminating research findings providing customized real-time news delivery. We have learned a great deal about the use of social media through the promotion of our article “Population Analysis of the Perfect Breast: A Morphometric Analysis” released in the September issue of the Journal.4 Authors should control press releases themselves to minimize bias, working directly with the public relations teams of scientific journals after acceptance of their article. These teams may have good connections with the press. By following the Plastic and Reconstructive Surgery Author Tool Kit advice, we have gained a following of 15,000 genuine Twitter users with over 12,000 profile views per week. The study was featured internationally in a number of magazines, newspapers, and countless blogs (Fig. 1).5–8 The article was the most viewed in Plastic and Reconstructive Surgery for 4 months after its publication. If a story has public interest, the journal may promote it by means of press releases6 or using media such as video.9Fig. 1: Blog of our September Plastic and Reconstructive Surgery article on Health magazine Web site. (Lombardi L. Available at: What the perfect breast looks like, according to men and women. http://news.health.com/2014/11/04/what-the-perfect-breast-looks-like-according-to-men-and-women/. Accessed April 7, 2015.)Article-level metrics measure impact at an article level instead of journal level. Other alternative metrics, or “altmetrics,” include full-text and PDF downloads and mentions in social media. Online “hit counts” and the number of tweets related to an article, or “tweetations,” correlate well with subsequent citations and therefore impact factor.10,11 Public appetite for science news is healthy and growing and may ultimately serve to support high-quality translational research with real-world application. For a small time investment, social media provides authors a way of disseminating information while minimizing bias.
