Full Text Available This review presents an extensive overview of a large number of microvalve and micropump designs with great variability in performance and operation. The performance of a given design varies greatly depending on the particular assembly procedure and there is no standardized performance test against which all microvalves and micropumps can be compared. We present the designs with a historical perspective and provide insight into their advantages and limitations for biomedical uses. (Note: This review has been adapted from a chapter from the upcoming textbook by Albert Folch, Introduction to BioMEMS, published by CRC Press.

Full Text Available Alcoholism is a big health problem in Spain. The objective of this study was to find out and to analyse books published in this field in Spain. ISBN Spanish database was chosen as a tool to retrieve them. Characteristics of this database were also studied. Books dealing with alcohol and alcoholism were retrieved (the words alcohol*, alcohol*, etanol*, etili* or beber* were searched. Authors, ISBN classification, year of publication, language (of publication and original and publishers were analysed.
One hundred and ninety-six books were analysed. An increase in the number of published books was observed in the last years studied; most of them were published between 1985 and 1993 (71 %. A great number (79% was written by personal authors. Most of the books (95% were published in Spanish. Twenty books (10% were translations. According to the ISBN classification, these books were grouped in 28 different topics. Most frequently covered areas were pathology, diseases and medical/therapeutical clinical practice (n=58, 30% and pharmacology/toxicology/drugs (n=43, 22%. Fourty per cent of the books was published by trade publishers, 26% by the Universities (47 -94%- were doctoral theses and 19% by public organizations.
It is concluded that the ISBN Spanish database can be a good tool to retrieve Spanish books dealing with alcoholism, but some limitations, that are extensively discussed, must be taken into account when a study of these characteristics is performed using this database.

Fleur T van de Wetering
Full Text Available CONTEXT: Since September 2005, the International Committee of Medical Journal Editors (ICMJE has required that randomised controlled trials (RCTs are prospectively registered in a publicly accessible database. After registration, a trial registration number (TRN is assigned to each RCT, which should make it easier to identify future publications and cross-check published results with associated registry entries, as long as the unique identification number is reported in the article. OBJECTIVE: Our primary objective was to evaluate the reporting of trial registration numbers in biomedical publications. Secondary objectives were to evaluate how many published RCTs had been registered and how many registered RCTs had resulted in a publication, using a sample of trials from the Netherlands Trials Register (NTR. DESIGN, SETTING: TWO DIFFERENT SAMPLES OF RCTS WERE EXAMINED: 1 RCTs published in November 2010 in core clinical journals identified in MEDLINE; 2 RCTs registered in the NTR with a latest expected end date of 31 August 2008. RESULTS: Fifty-five percent (166/302 of the reports of RCTs found in MEDLINE and 60% (186/312 of the published reports of RCTs from the NTR cohort contained a TRN. In both samples, reporting of a TRN was more likely in RCTs published in ICMJE member journals as compared to non-ICMJE member journals (MEDLINE 58% vs. 45%; NTR: 70% vs. 49%. Thirty-nine percent of published RCTs in the MEDLINE sample appear not to have been registered, and 48% of RCTs registered in the NTR seemed not to have been published at least two years after the expected date for study completion. CONCLUSION: Our results show that further promotion and implementation of trial registration and accurate reporting of TRN is still needed. This might be helped by inclusion of the TRN as an item on the CONSORT checklist.

Numbers, scale and symbols: the public understanding of nanotechnology

Nanotechnology will be an increasing part of the everyday lives of most people in the world. There is a general recognition that few people understand the implications of the technology, the technology itself or even the definition of the word. This lack of understanding stems from a lack of knowledge about science in general but more specifically difficulty in grasping the size scale and symbolism of nanotechnology. A potential key to informing the general public is establishing the ability to comprehend the scale of nanotechnology. Transitioning from the macro to the nanoscale seems to require an ability to comprehend scales of one-billion. Scaling is a skill not common in most individuals and tests of their ability to extrapolate size based upon scaling a common object demonstrates that most individuals cannot scale to the extent needed to make the transition to nanoscale. Symbolism is another important vehicle to providing the general public with a basis to understand the concepts of nanotechnology. With increasing age, individuals are able to draw representations of atomic scale objects, but these tend to be iconic and the different representations not easily translated. Ball and stick models are most recognized by the public, which provides an opportunity to present not only useful symbolism but also a reference point for the atomic scale.
The number of scholarly documents on the public web.
Khabsa, Madian; Giles, C Lee
2014-01-01
The number of scholarly documents available on the web is estimated using capture/recapture methods by studying the coverage of two major academic search engines: Google Scholar and Microsoft Academic Search. Our estimates show that at least 114 million English-language scholarly documents are accessible on the web, of which Google Scholar has nearly 100 million. Of these, we estimate that at least 27 million (24%) are freely available since they do not require a subscription or payment of any kind. In addition, at a finer scale, we also estimate the number of scholarly documents on the web for fifteen fields: Agricultural Science, Arts and Humanities, Biology, Chemistry, Computer Science, Economics and Business, Engineering, Environmental Sciences, Geosciences, Material Science, Mathematics, Medicine, Physics, Social Sciences, and Multidisciplinary, as defined by Microsoft Academic Search. In addition, we show that among these fields the percentage of documents defined as freely available varies significantly, i.e., from 12 to 50%.

As we found no recent published reports on the amount and kind of research published from Danish hospitals without university affiliation, we have found it relevant to conduct a bibliometric survey disclosing these research activities. We retrieved all scientific papers published in the period 2000-2009 emanating from all seven Danish non-university hospitals in two regions, comprising 1.8 million inhabitants, and which were registered in a minimum of one of the three databases: PubMed MEDLINE, Thomson Reuters Web of Science and Elsevier's Scopus. In 878 of 1,252 papers, the first and/or last author was affiliated to a non-university hospital. Original papers made up 69% of these publications versus 86% of publications with university affiliation on first or last place. Case reports and reviews most frequently had authors from regional hospitals as first and/or last authors. The total number of publications from regional hospitals increased by 48% over the 10-year period. Publications were cited more often if the first or last author was from a university hospital and even more so if they were affiliated to foreign institutions. Cardiology, gynaecology and obstetrics, and environmental medicine were the three specialities with the largest number of regional hospital publications. A substantial number of scientific publications originate from non-university hospitals. Almost two thirds of the publications were original research published in international journals. Variations between specialities may reflect local conditions. not relevant. not relevant.

The goals, methods, priorities and perspectives of archaeologists as well as historians have been catalyzed by his fieldwork, publications, and wide presentation of his results. It is not too much to say that the consciousness of many of us has been raised, our agenda has changed, as a result of his "New World-style" anthropologically and environmentally grounded archaeology

In between, major players include Galileo, Harvey, Leeuwenhoek, and Halley; Graunt and Petty; Jefferson and Franklin; Lavoisier, Sinclair, Pinel and Louis; Guerry and Quetelet. The book tells of the spread of what Cohen refers to as the “quantifying spirit” from physical science to “political arithmetic” (Sir William Petty, economics, and the beginning of psychiatry, sociology, medical statistics, and public health.

Public enemy number one: the US Advertising Council's first drug abuse prevention campaign.
Niesen, Molly
2011-01-01
This article explores the Advertising Council's first national drug abuse prevention campaign in the 1970s. Scholarship thus far has demonstrated the ways in which the issue of drug abuse represented a chief political strategy for President Nixon. Evidence from major trade press publications, congressional hearings, and an array of archival sources suggest that this campaign was also part of a public relations crusade on behalf of the advertising industry in response to public criticism of its role in abetting a culture of drug dependence. These institutional and political pressures helped shape drug abuse prevention in the 1970 s and for the decades that followed.

Full Text Available Security is required to transmit confidential information over the network. Security is also demanding in wide range of applications. Cryptographic algorithms play a vital role in providing the data security against malicious attacks. RSA algorithm is extensively used in the popular implementations of Public Key Infrastructures. In asymmetric key cryptography, also called Public Key cryptography, two different keys (which form a key pair are used. One key is used for encryption and only the other corresponding key must be used for decryption. No other key can decrypt the message – not even the original (i.e. the first key used for encryption. In this paper, we have proposed an improved approach of RSA algorithm using two public key pairs and using some mathematical logic rather than sending one public key d irectly.Because if an attacker has an opportunity of getting the public key componet they can find private key value by brute force search. General Terms: Cryptography, network security

The assessment of scientific publications is an integral part of the scientific process. Here we investigate three methods of assessing the merit of a scientific paper: subjective post-publication peer review, the number of citations gained by a paper, and the impact factor of the journal in which the article was published. We investigate these methods using two datasets in which subjective post-publication assessments of scientific publications have been made by experts. We find that there are moderate, but statistically significant, correlations between assessor scores, when two assessors have rated the same paper, and between assessor score and the number of citations a paper accrues. However, we show that assessor score depends strongly on the journal in which the paper is published, and that assessors tend to over-rate papers published in journals with high impact factors. If we control for this bias, we find that the correlation between assessor scores and between assessor score and the number of citations is weak, suggesting that scientists have little ability to judge either the intrinsic merit of a paper or its likely impact. We also show that the number of citations a paper receives is an extremely error-prone measure of scientific merit. Finally, we argue that the impact factor is likely to be a poor measure of merit, since it depends on subjective assessment. We conclude that the three measures of scientific merit considered here are poor; in particular subjective assessments are an error-prone, biased, and expensive method by which to assess merit. We argue that the impact factor may be the most satisfactory of the methods we have considered, since it is a form of pre-publication review. However, we emphasise that it is likely to be a very error-prone measure of merit that is qualitative, not quantitative.

Full Text Available As international efforts to increase the coverage of artemisinin-based combination therapy in public health sectors gather pace, concerns have been raised regarding their continued indiscriminate presumptive use for treating all childhood fevers. The availability of rapid-diagnostic tests to support practical and reliable parasitological diagnosis provides an opportunity to improve the rational treatment of febrile children across Africa. However, the cost effectiveness of diagnosis-based treatment polices will depend on the presumed numbers of fevers harbouring infection. Here we compute the number of fevers likely to present to public health facilities in Africa and the estimated number of these fevers likely to be infected with Plasmodium falciparum malaria parasites.We assembled first administrative-unit level data on paediatric fever prevalence, treatment-seeking rates, and child populations. These data were combined in a geographical information system model that also incorporated an adjustment procedure for urban versus rural areas to produce spatially distributed estimates of fever burden amongst African children and the subset likely to present to public sector clinics. A second data assembly was used to estimate plausible ranges for the proportion of paediatric fevers seen at clinics positive for P. falciparum in different endemicity settings. We estimated that, of the 656 million fevers in African 0-4 y olds in 2007, 182 million (28% were likely to have sought treatment in a public sector clinic of which 78 million (43% were likely to have been infected with P. falciparum (range 60-103 million.Spatial estimates of childhood fevers and care-seeking rates can be combined with a relational risk model of infection prevalence in the community to estimate the degree of parasitemia in those fevers reaching public health facilities. This quantification provides an important baseline comparison of malarial and nonmalarial fevers in different

Astronomy for Astronomical Numbers - Education and Public Outreach with Massive Open Online Classes
Impey, C.; Buxner, S.; Wenger, M.; Formanek, M.
2015-12-01
Massive Open Online Classes (MOOCs) represent a powerful new mode of education and public outreach. While early hype has often given way to disappointment over the typically low completion rates, retaining the interest of free-choice learners is always a challenge, and the worldwide reach and low cost of of these online classes is a democratizing influence in higher education. We have used providers Udemy and Coursera to reach over 60,000 adults with an astronomy course that covers the recent research results across the subject from comets to cosmology. In addition to measures of participation, completion, and performance, we have administered surveys of the learners that measure science literacy, attitudes towards science and technology, and sources of information about science. Beyond the usual core of video lectures and quizzes, we have used peer reviewed writing assignments, observing project, and citizen science to create a richer learning environment. Research on MOOCs is still in its early stages, but we hope to learn what factors contribute most to student engagement and completion in these online settings.

In this study, 40 Asian countries were included. The information regarding Asian countries, their GDP per capita, spending on R&D, total number of universities and indexed scientific journals were collected. We recorded the bibliometric indicators, including total number of research documents, citations per document and H-index in various science and social sciences subjects during the period 1996-2011. The main sources for information were World Bank, SCI-mago/Scopus and Web of Science; Thomson Reuters. The mean per capita GDP for all the Asian countries is 14448.31±2854.40 US$, yearly per capita spending on R&D 0.64±0.16 US$, number of universities 72.37±18.32 and mean number of ISI indexed journal per country is 17.97±7.35. The mean of research documents published in various science and social science subjects among all the Asian countries during the period 1996-2011 is 158086.92±69204.09; citations per document 8.67±0.48; and H-index 122.8±19.21. Spending on R&D, number of universities and indexed journals have a positive correlation with number of published documents, citations per document and H-index in various science and social science subjects. However, there was no association between the per capita GDP and research outcomes. The Asian countries who spend more on R&D have a large number of universities and scientific indexed journals produced more in research outcomes including total number of research publication, citations per documents and H-index in various science and social science subjects.

Cheetahs in managed zoological collections do not reproduce efficiently, a problem that may be related to environmental/management stressors. In this study, we examined 17 adult female cheetahs to determine the influence of two environmental factors, (1) being housed on- or off-exhibit and (2) number of adult conspecifics (males and/or females) in nearby enclosures, on profiles and concentrations of ovarian and adrenal hormones. Secondarily, we assessed a subset of group-housed siblings (n=5 females in groups of 2 or 3) for effects of long-term cohabitation. All of the females demonstrated waves of estrogen excretion (indicative of ovarian activity) as well as occasional periods of no estrogen production (anestrus). Glucocorticoid and estrogen concentrations were correlated within an individual (rs=0.53; P0.05) on estrogen or glucocorticoid metabolite excretory patterns. Although we recently reported that public exposure can negatively affect sperm production, ovarian steroidogenesis in females was unaffected. There also was no evidence of hyper-adrenal activity. Thus, different methods of ex situ management appear to have minimal influence on ovarian function or stress susceptibility of female cheetahs. Copyright © 2016 Elsevier Inc. All rights reserved.

The inactive H and L No. 1 Municipal Landfill Response Action Site is south of Danville between the Vermilion River and Interstate 74 in Vermilion County, Illinois. The landfill operated from the 1940s to 1974, accepting domestic and industrial waste from the area. The site has a history of problems with leachate flows, seeps, and persistent odors. Before remedial activities, leachate would flow through the cover soil, predominantly along the northeastern part of the landfill. A leachate collection system was constructed in January 1992 and is currently in operation. The investigation and cleanup of contaminated soils and sediments on two adjacent residential properties are pending. Site-related contaminants currently pose no apparent public health hazard because human exposure to contaminated media is not occurring at levels of health concern.

Available as an eBook.Popular books on quantitative literacy need to be easy to read, reasonably comprehensive in scope, and include examples that are thought-provoking and memorable. In contrast to textbooks, popular books can dispense with exercises and structure, and instead offer an informal voice and an inviting style. In this genre John Allen Paulos’ Innumeracy is widely regarded as a classic. However, Paulos' book is out of date, and it takes a whimsical approach to many topics. The goal of this review is to acquaint the reader with two more recent entries into the genre. What the Numbers Say by Derrick Niederman and David Boyum takes an expansive view of quantitative literacy. The Numbers Game by Michael Blastland and Andrew Dilnot, on the other hand, focuses on reasoning surrounding statistics and uncertainty in contemporary society. The Numbers Game is a revised American edition of The Tiger That Isn’t, which grew out of a BBC radio program, More or Less.

The collective cheetah (Acinonyx jubatus) population in zoological institutions has never been self-sustaining because of challenges in natural reproduction. A retrospective analysis of North American zoo-breeding records has revealed that >90% of litters produced since 2003 occurred in facilities 'off-display' from the public. We examined seminal, endocrine, and behavioral traits of 29 adult male cheetahs that were: 1) managed in public exhibit or off-display facilities; 2) maintained by different numbers of cheetah-specific care-givers; and 3) living adjacent to varying numbers of adult conspecifics. Cheetahs housed off-display produced more total motile sperm/ejaculate (P = 0.04) than on-exhibit males. This finding was mirrored in our laboratory's historical records where two-fold more total motile sperm (P 3 care-givers. Exposure to high numbers of conspecifics within the same institution did not impact (P > 0.05) seminal traits, and presence of the public, care-giver number, or animals/facility had no influence (P > 0.05) on androgen or glucocorticoid excretion or other behavioral metrics. Findings indicate that male cheetahs are sensitive to general public exposure and too many care-givers, resulting in compromised motile sperm output/ejaculate with mechanism of action unrelated to altered androgen or glucocorticoid excretion.

Do public employees work "for the money?" Do financial incentives determine their work effort? The literature gives conflicting answers, but Frey (1997) offers a possible explanation: If financial incentives are perceived as supportive, they can "crowd in" intrinsic motivation and increase the work...... effort. But if financial incentives are perceived as controlling, the intrinsic motivation is "crowded out," and the work effort decreases with increasing financial incentives to work. However, the empirical evidence concerning Frey's proposition is limited, and our article aims to fill part of this gap...... that the more supportive employees consider the incentives to be, the more financial incentives motivate researchers to increase publication....

The Sandoval Zinc site occupies about 13 acres southeast of Sandoval in Marion County, Illinois. It is an abandoned primary and secondary zinc smelter that was next to a coal mining operation. Smelting waste may have been transported off the site and used as fill in Sandoval and other nearby communities. Airborne emissions occurred during regular operations and accidental fires. Surface water runoff transported wastes from the site into adjacent ditches, creeks, ponds, and farm properties. Overall, the Sandoval Zinc site poses no apparent public health hazard to most of the population in Sandoval. The site may be a public health hazard to preschool children with excessive hand-to-mouth activity exposed to residential surface soils with high levels of lead. However, blood sample results from children in a day care near the site did not show elevated levels of lead.

Concerns arising from misunderstandings about radiation are often cited as a main reason for public antipathy towards nuclear development and impede decision-making by governments and individuals. A lack of information about everyday sources of radiation exposure that is accessible, relatable and factual contributes to the problem. As part of its efforts to be a fact-based source of information on nuclear issues, the Sylvia Fedoruk Canadian Centre for Nuclear Innovation has developed an on-line Canadian Radiation Dose Calculator as a tool to provide context about common sources of radiation. This paper discusses the development of the calculator and describes how the Fedoruk Centre is using it and other tools to support public engagement on nuclear topics. (author)

The 1950s were a period of great hope and promise for Ghana. Ghana became the first country south of the Sahara to become independent. Though the independence struggle was led by men they were aided by women. Women played a key role in mobilizing people for the struggle at the grassroot level. After independence the efforts of women were not rewarded with appointments to public office. This was rectified in 1965 through an affirmative action. However succeeding Governments since then have not...

The Re-Solve National Priorities List (NPL) site is a 6-acre area situated in the town of Dartmouth, Massachusetts. During the years 1956-1980 the Re-Solve Company distilled industrial solvents on-site. Waste materials from this process were disposed of by burning solvents in four on-site lagoons and spreading waste oils in various portions of the site. Elevated levels of polychlorinated biphenyls (PCBs) and volatile organic compounds (VOCs) were measured in soils throughout the site in 1981, and it was added to the NPL in December 1982. This site is characterized as a past and present public health hazard primarily due to the likely past and present exposure to PCBs through the consumption of PCB contaminated fish and eels from area water bodies. Based upon results of fish sampling that detected PCBs in area eel, the Massachusetts Department of Public Health issued and updated an advisory in 1986 and 1994 recommending that people not eat the fish and eel caught in these affected waters. The potentially exposed population; therefore, include area fishers who may be consuming contaminated fish or eel.

The Jennison-Wright Corporation (J-W) is a National Priorities List (NPL) site in Madison County, Illinois, in the northern section of granite City. The J-W facility engaged in wood treatment of railroad ties and wood blocks using creosote, pentachlorophenol, and zinc naphthanate. Soil contamination also exists off the site from runoff, disposal, and air deposition. Based on available information, the J-W site is considered a public health hazard because of the risk to human health resulting from past, present, and future exposure to soil contaminants. The reason for this conclusion is exposure to soil contaminants originating from on- and off-site areas, including dermal exposure in heavily contaminated enfenced off-site areas and the increase in cancer risk from exposure to these soil contaminants. Future concerns include contaminated groundwater migration and subsequent exposure through ingestion and inhalation of contaminants from the site. Substances of concern include creosote and coal tar and their associated polycyclic aromatic hydrocarbons, pentachlorophenol, dioxins, and furans.

This report presents recently published information and on-going research on the various areas of gas supersaturation. Growing interest in the effects of chronic gas supersaturation on aquatic animals has been due primarily to heavy mortality of salmonid species under hatchery conditions. Extensive examination of affected animals has failed to consistently identify pathogenic organisms. Water quality sampling has shown that chronic levels of gas supersaturation are commonly present during a significant period of the year. Small marine fish larvae are significantly more sensitive to gas supersaturation than salmonids. Present water quality criteria for gas supersaturation are not adequate for the protection of either salmonids under chronic exposure or marine fish larvae, especially in aquaria or hatcheries. To increase communication between interested parties in the field of gas supersaturation research and control, addresses and telephone numbers of all people responding to the questionnaire are included. 102 refs.

How to quantify the impact of a researcher's or an institution's body of work is a matter of increasing importance to scientists, funding agencies, and hiring committees. The use of bibliometric indicators, such as the h-index or the Journal Impact Factor, have become widespread despite their known limitations. We argue that most existing bibliometric indicators are inconsistent, biased, and, worst of all, susceptible to manipulation. Here, we pursue a principled approach to the development of an indicator to quantify the scientific impact of both individual researchers and research institutions grounded on the functional form of the distribution of the asymptotic number of citations. We validate our approach using the publication records of 1,283 researchers from seven scientific and engineering disciplines and the chemistry departments at the 106 U.S. research institutions classified as "very high research activity". Our approach has three distinct advantages. First, it accurately captures the overall scien...

Sun, in the IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, vol.39, no.1, Jan 1992, pp.8-17In this paper, we propose a joint scheme which combines redundant residue number systems (RRNS) with module isolation (MI) for mitigating single event multiple bit upsets (SEMBUs) in datapath. The proposed hardening scheme employs redundant residues to improve the fault tolerance for datapath and module spacings to guarantee that SEMBUs caused by charge sharing do not propagate among the operation channels of different moduli. The features of RRNS, such as independence, parallel and error correction, are exploited to establish the radiation hardening architecture for the datapath in radiation environments. In the proposed

Full Text Available The migration issue is a debatable one not only from a theoretical point of view but from the policy options as well. The progress in explaining various aspects of international migration such as migration strategy, from individual to family strategy, the way of entering the new country, from “chain” to “network migration” and trans-nationality etc. has not always been followed by the most appropriate policy options. Because of political interest, policy makers are more sensitive to the public opinion perception on migration than to the scientific opinions concerning the balance between advantages and disadvantages of migrants’ presence.

Current genome-wide association studies (GWAS) use commercial genotyping microarrays that can assay over a million single nucleotide polymorphisms (SNPs). The number of SNPs is further boosted by advanced statistical genotype-imputation algorithms and large SNP databases for reference human populations. The testing of a huge number of SNPs needs to be taken into account in the interpretation of statistical significance in such genome-wide studies, but this is complicated by the non-independence of SNPs because of linkage disequilibrium (LD). Several previous groups have proposed the use of the effective number of independent markers (M(e)) for the adjustment of multiple testing, but current methods of calculation for M(e) are limited in accuracy or computational speed. Here, we report a more robust and fast method to calculate M(e). Applying this efficient method [implemented in a free software tool named Genetic type 1 error calculator (GEC)], we systematically examined the M(e), and the corresponding p-value thresholds required to control the genome-wide type 1 error rate at 0.05, for 13 Illumina or Affymetrix genotyping arrays, as well as for HapMap Project and 1000 Genomes Project datasets which are widely used in genotype imputation as reference panels. Our results suggested the use of a p-value threshold of ~10(-7) as the criterion for genome-wide significance for early commercial genotyping arrays, but slightly more stringent p-value thresholds ~5 × 10(-8) for current or merged commercial genotyping arrays, ~10(-8) for all common SNPs in the 1000 Genomes Project dataset and ~5 × 10(-8) for the common SNPs only within genes.

Full Text Available Among the set goals of improving book consumption in Slovenia the National Culture Program 2004-2007 also includes encouraging the development of network of bookshops and ‘quality’ bookshops, that will be evenly distributed across Slovenia. The program suggests them to be formed within the framework of already existing public cultural institutions. Book consumption in Slovenia has been characterised by poorly developed retail book market and well developed network of public libraries with a high number of book lendings that serves as a substitute for the paperback market as it is known in bigger language communities abroad. Along with surveying the possibilities of directing the libraries towards book marketing (as well, the paper also examines the historical development of commercial publishing companies / bookshops / libraries, existing in Europe in 18th and 19th century and in some places existing side by side with public libraries until the middle of 20th century. The paper shows that the present ratio between bookshops and libraries on some big book markets is different than in Slovenia, as libraries are loosing patrons as a consequence of the growth of big bookshop chains. A characteristic feature of book consumption in Slovenia can be seen in the use of the internet in libraries as well as bookshops. The ‘merging’ of the marketing segment and book lending is to a smaller extent already under way abroad, where large online bookshops encourage libraries by means of provision to act as the mediator in the sale of books. In this way, a library can turn into a bookshop with the help of connections via ISBN numbers, without having to jeopardise their original mission.

Since about the early seventies no proper book on variable stars has been written. The probable reason is the explosive growth of the field of variable-star research during the 25 years since. It was not only the amount of observational data which grew so fast, but also the number of new types of variable stars and the knowledge of the causes of their variability. Variable stars also became of fastly growing importance for distance determinations, for the physics of stellar interiors and for stellar evolution. The two editors, together with seven other experts on variable stars have now found a perfect recipe to write a conveniently-sized book on variable stars. The time was ripe. They compiled a pictorial atlas of at least 200 typical light curves of tens of different kinds of variable stars. The book also gives a clear introduction to the historical background, the photometric systems, the nomenclature and the classifications. Each chapter provides a detailed account of each subclass and gives a concise description of the physical processes responsible for the variations. All specific variables discussed in the text can easily be located with the aid of object-name and subject indexes. The reference list contains about 600 entries, a guarantee that one can access a particular subject quickly and in debt. The quality of the figures and the tables is very good. Very useful is the inclusion of three lists, 'Journal abbreviations', 'Acronyms and abbreviations' and 'Addresses of interest', and of three tables concerning constellation names, Julian dates, and specialized newsletters on variable stars. This unique guide will be absolutely invaluable to students taking courses in variable-star research, as well as for professional and amateur astronomers.

We define a new class of numbers based on the first occurrence of certain patterns of zeros and ones in the expansion of irracional numbers in a given basis and call them Sagan numbers, since they were first mentioned, in a special case, by the North-american astronomer Carl E. Sagan in his science-fiction novel "Contact." Sagan numbers hold connections with a wealth of mathematical ideas. We describe some properties of the newly defined numbers and indicate directions for further amusement.

Fibonacci numbers date back to an 800-year-old problem concerning the number of offspring born in a single year to a pair of rabbits. This book offers the solution and explores the occurrence of Fibonacci numbers in number theory, continued fractions, and geometry. A discussion of the ""golden section"" rectangle, in which the lengths of the sides can be expressed as a ration of two successive Fibonacci numbers, draws upon attempts by ancient and medieval thinkers to base aesthetic and philosophical principles on the beauty of these figures.

Full Text Available China is one of the first countries to use marine materia medica for treating diseases. Ancient books on Chinese herbology, such as Shennong Bencaojing (Shennong’s Classic of Materia Medica, Xinxiu Bencao (Newly Revised Materia Medica and Bencao Gangmu (Compendium of Materia Medica, have detailed more than 110 marine herbs and thousands of marine herbal formulas (including those for Chinese food therapy. A great deal of information on marine herbs and their applications in medicine, collected over thousands of years, has provided an important foundation for modern research in the area of marine drugs. Thanks to these records and references, the research and development of modern Chinese marine drugs continue to evolve and mature. Since the middle of the 20th century, special attention has been paid to traditional Chinese medicine, resulting in a significant increase in the number of newly discovered marine herbs. Comprehensive surveys in the past have also created a wealth of data on the pharmacology, chemistry, biology and ecology of marine medicinal bioresources. After thousands of years of research, historical references to traditional marine herbs are scattered throughout ancient books, local chronicles, medical books, or monographs on medicinal herbs. Unfortunately, there is no systematic way to collate or scientifically verify these references. Furthermore, during the last century, scientists around the world have accumulated large quantities of information on marine natural products, but these are also scattered throughout academic books and journals.

through using mathematical names for the numbers such as one-ten-one for 11 and five-ten-six for 56. The project combines the renaming of numbers with supporting the teaching with the new number names. Our hypothesis is that Danish children have more difficulties learning and working with numbers, because...... the Danish number names are more complicated than in other languages.

Financial Intelligence for Entrepreneurs: What You Really Need to Know about the Numbers, (Boston MA: Harvard Business Press, 2008. 285 pp. ISBN 978-1-4221-1915-0. From “The art of finance (and why it matters” (Part One through “Creating a financially intelligent company” (Part Eight, Financial Intelligence for Entrepreneurs is an engaging explanation and appreciation of financial statements and financial ratios. Short, easily digested chapters; just-in-time boxes to introduce terminology; easy, direct, in-text calculations from bare-bones, hypothetical financial statements to illustrate concepts; a 44-page appendix of crafted exercises on the income statement, balance sheet, cash-flow statement, and financial ratios from two public companies for deeper understanding; a detailed 19-page index for quick, after-you’ve-read-it navigation – all make for an efficient learning opportunity for readers who want a painless way to know about the numbers used in the world of business. Two quantitative literacy principles emerge as themes. The first is the “art of finance” (social construction: that is, the numbers are not totally objective; to varying extents, they reflect decisions, assumptions, and estimates in the accounting. The second is that ratios provide a window into the story that financial statements are able to tell. Written for entrepreneurs and company owners, the book ends with OBM (open-book management—a management philosophy based on financial literacy. The vision of this book is businesses in which all employees are financially literate and managers and owners are financially intelligent.

This text presents the Eulerian numbers in the context of modern enumerative, algebraic, and geometric combinatorics. The book first studies Eulerian numbers from a purely combinatorial point of view, then embarks on a tour of how these numbers arise in the study of hyperplane arrangements, polytopes, and simplicial complexes. Some topics include a thorough discussion of gamma-nonnegativity and real-rootedness for Eulerian polynomials, as well as the weak order and the shard intersection order of the symmetric group. The book also includes a parallel story of Catalan combinatorics, wherein the Eulerian numbers are replaced with Narayana numbers. Again there is a progression from combinatorics to geometry, including discussion of the associahedron and the lattice of noncrossing partitions. The final chapters discuss how both the Eulerian and Narayana numbers have analogues in any finite Coxeter group, with many of the same enumerative and geometric properties. There are four supplemental chapters throughout, ...

online are nomenclaturally unavailable; (6) nomenclatural information provided on online websites that do not have a fixed content and format, with ISSN or ISBN, is unavailable. We give precise examples of many of these nomenclatural problems. Several of them, when they arise, are due to the fact that the availability of nomenclatural novelties now depends on information that will have to be sought not from the work itself but from extrinsic evidence. As shown by several examples discussed here, an electronic document can be modified while keeping the same DOI and publication date, which is not compatible with the requirements of zoological nomenclature. Therefore, another system of registration of electronic documents as permanent and inalterable will have to be devised. ZooBank also clearly needs to be improved in several respects. Mention in a work of its registration number (LSID) in ZooBank would seem to be possible only if this registration has occurred previously, but some works that have purportedly been registered in ZooBank are in fact missing on this web application. In conclusion, we offer recommendations to authors, referees, editors, publishers, libraries and the International Commission on Zoological Nomenclature, in the hope that such problems can be limited along with the potential chaos in zoological nomenclature that could result, if careful attention is not paid to the problems we highlight here, from a somewhat misplaced, and perhaps now widespread, understanding that electronic publication of nomenclatural novelties is now allowed and straightforward. We suggest that, as long as the problematic points linked to the new amendment and to electronic publication as a whole are not resolved, nomenclatural novelties continue to be published in paper-printed journals that have so far shown editorial competence regarding taxonomy and nomenclature, which is not the case of several recent electronic-only published journals.

Making use of the framework of the traditional public-key algorithm RSA and ElGamal, proposed a chaotic public-key encryption algorithm based on extending discrete Chebyshev polynomials' definition domain to Real number. Its security is based on the intractability of the integer factorization problem as RSA,and it is able to resist the chosen cipher-text attack against RSA and easy to be implemented.

THE last digit of my home phone number in Beijing is 4. “So what?” European readers might ask.This was my attitude when I first lived in China; I couldn't understand why Chinese friends were so shocked at my indifference to the number 4. But China brings new discoveries every day, and I have since seen the light. I know now that Chinese people have their own ways of preserving their well being, and that they see avoiding the number 4 as a good way to stay safe.

Although mathematics majors are usually conversant with number theory by the time they have completed a course in abstract algebra, other undergraduates, especially those in education and the liberal arts, often need a more basic introduction to the topic.In this book the author solves the problem of maintaining the interest of students at both levels by offering a combinatorial approach to elementary number theory. In studying number theory from such a perspective, mathematics majors are spared repetition and provided with new insights, while other students benefit from the consequent simpl

In this intriguing book, John Barnes takes us on a journey through aspects of numbers much as he took us on a geometrical journey in Gems of Geometry. Similarly originating from a series of lectures for adult students at Reading and Oxford University, this book touches a variety of amusing and fascinating topics regarding numbers and their uses both ancient and modern. The author intrigues and challenges his audience with both fundamental number topics such as prime numbers and cryptography, and themes of daily needs and pleasures such as counting one's assets, keeping track of time, and enjoying music. Puzzles and exercises at the end of each lecture offer additional inspiration, and numerous illustrations accompany the reader. Furthermore, a number of appendices provides in-depth insights into diverse topics such as Pascal’s triangle, the Rubik cube, Mersenne’s curious keyboards, and many others. A theme running through is the thought of what is our favourite number. Written in an engaging and witty sty...

This book provides an introduction to the topic of transcendental numbers for upper-level undergraduate and graduate students. The text is constructed to support a full course on the subject, including descriptions of both relevant theorems and their applications. While the first part of the book focuses on introducing key concepts, the second part presents more complex material, including applications of Baker’s theorem, Schanuel’s conjecture, and Schneider’s theorem. These later chapters may be of interest to researchers interested in examining the relationship between transcendence and L-functions. Readers of this text should possess basic knowledge of complex analysis and elementary algebraic number theory.

我国刑法中的贿赂外国公职人员或者国际公共组织官员罪,其渊源在于《联合国反腐败公约》。但是,在我国将国际公约内化为国内刑法的过程中,本罪的若干方面仍与公约存在脱节之处。笔者认为,应将本罪构成要件中的＂不正当商业利益＂修正为＂不正当利益＂;重新界定＂外国公职人员和国际公共组织官员＂的内涵;扩大＂贿赂＂的范畴;最后提出在我国刑法中应增设外国公职人员、国际公共组织官员受贿罪。%the root of the bribery crime of foreign public officials or officials of public international organizations in China＇s criminal law is the ＂United Nations Convention against Corruption.＂ However,in the process of changing the international conventions into the domestic criminal law, there are still a number of aspects of this crime out of touch with the Convention. The author believed that the constitute element of the crime,the ＂unfair commercial interests＂ should be modified to ＂ improper benefit＂;redefined the meaning of ＂foreign public officials and officials of public international organizations＂;expanded the category of ＂bribe＂;and finally proposed to add the bribery crime of foreign public officials or officials of public international organizations in China＇s Criminal Law.

This publication lists all report number codes processed by the Office of Scientific and Technical Information. The report codes are substantially based on the American National Standards Institute, Standard Technical Report Number (STRN)-Format and Creation Z39.23-1983. The Standard Technical Report Number (STRN) provides one of the primary methods of identifying a specific technical report. The STRN consists of two parts: The report code and the sequential number. The report code identifies the issuing organization, a specific program, or a type of document. The sequential number, which is assigned in sequence by each report issuing entity, is not included in this publication. Part I of this compilation is alphabetized by report codes followed by issuing installations. Part II lists the issuing organization followed by the assigned report code(s). In both Parts I and II, the names of issuing organizations appear for the most part in the form used at the time the reports were issued. However, for some of the more prolific installations which have had name changes, all entries have been merged under the current name.

Objective In many resource-limited settings, people from rural areas migrate to urban hubs in search of work. Thus, urban public-sector HIV clinics in South Africa (SA) often cater to both local residents and patients from other provinces and/or countries. The objective of this analysis was to compare programmatic treatment outcomes by citizenship status in an urban clinic in SA. Setting An urban public-sector HIV treatment facility in Johannesburg, SA. Participants We included all antiretroviral therapy (ART)-naïve, non-pregnant patients who initiated standard first-line treatment from January 2008 to December 2013. 12 219 patients were included and 59.5% were women. Primary outcome measure Patients were followed from ART initiation until death, transfer, loss to follow-up (LTF), or data set closure. We describe attrition (mortality and LTF) stratified by SA citizenship status (confirmed SA citizens (with national ID number), unconfirmed SA citizens (no ID), and foreign nationals) and model the risk of attrition using Cox proportional hazards regression. Results 70% of included patients were confirmed SA citizens, 19% were unconfirmed SA citizens, and 11% were foreign nationals. Unconfirmed SA citizens were far more likely to die or become LTF than other patients. A similar proportion of foreign nationals (18.2%) and confirmed SA citizens (17.7%) had left care at 1 year compared with 47.0% of unconfirmed SA citizens (adjusted hazard ratio (aHR) unconfirmed SA vs confirmed SA: 2.68; 95% CI 2.42 to 2.97). By the end of follow-up, 75.5% of unconfirmed SA citizens had left care, approximately twice that of any other group. Conclusions Unconfirmed SA citizens were more likely to drop out of care after ART initiation than other patients. Further research is needed to determine whether this observed attrition is representative of migration and/or self-transfer to another HIV clinic as such high rates of attrition pose challenges for the success of the national ART

环境法上针对尾号限行的授权，并不足以支撑其正当性。因为这种“污染防治手段”事实上还具有“交通管制”与“物权限制”的效果。学界现有讨论集中于公权对私有财产权的限制问题，却忽略了尾号限行是针对“特定道路”，而非“不特定车辆”作出的事实。对此，公物理论架起了机动车价值发挥与道路使用的桥梁，并逻辑自洽地将尾号限行的行为形式、内容、效果作为公物管理权的运作过程而纳入。如将尾号限行理解为“道路管理行为”，则其合法性来自于国家对道路的所有权或《公路法》第8条第2款的概括性管理权。尽管这种正当性根据要受到“交通目的”的限制，但却是对基于“污染防治目的”作出的限行行为正当性的补充。%The authorization of the environmental law to the traffic restrictions based on the last digit of license plate numbers is not sufficient to support its legitimacy, because this restriction is not only an ‘instrument to control air pollution’, but also effect of ‘traffic control’ and ‘restriction on property right’ in fact. The existing related discussions focus on restricting private property right by public right, while neglects the fact that the restriction is for ‘specific road’ instead of ‘unspecified vehicles’. For this, the public property theory acts as a bridge between motor vehicles' value exertion and road usage, and brings the behavior form, content and effect of the restriction under public property management right operation course logically. If the restriction is made of ‘road management behavior’, its legitimacy is from the state's ownership of road or the general management right directly granted by the article 8.2 of the Law of Road. Although such legitimacy is limited to ‘traffic purpose’, it is the supplement to the legitimacy of the restriction behavior made according to

Full Text Available Backhaus examines urban multilingualism in the linguistic landscape of Tokyo, the capital city of Japan. In this monograph, the linguistic landscape is seen as a sub-discipline of sociolinguistics. The significance of this monograph to linguistic landscape research is that it represents the first comprehensive approach tackling multilingualism in the linguistic landscape and overcoming a range of methodological problems facing former studies. In this sense, Backhaus’s approach in data collection and analysis may help linguistic landscapers and researchers to undertake research in multilingualism in the linguistic landscape. The current work comprises acknowledgements, a foreword by Bernard Spolsky, six chapters, an appendix, references, and an index. While the first three chapters represent an introduction and theoretical background, the fourth chapter in turn paves the way for the application of an empirical study in Tokyo’s linguistic landscape, applied in chapter five. That chapter one discusses the examination of written language in the public space of metropolises is the bulk of Backhaus’s work. In this respect, the author (p.1 refers to previous studies such as Halliday (1972, who considers the city not only a place of talk, but also a place of writing and reading. At the same time, this work focuses on ‘urban language contact in the written medium: the languages of the signs’. Backhaus (p.1 holds: Every urban environment is a myriad of written messages on public display: office and shop signs, billboards, and neon advertisements, traffic signs, topographic information and area maps, emergency guidance and political poster campaigns, stone inscriptions, and enigmatic graffiti discourse. The author maintains that these messages contribute to the making of the linguistic landscape of any given place. In chapter two, Semiotic Background and Terminology, Backhaus gives an introduction to the main features of language use on signs

The political consequences of the crisis mainly stem from rising unemployment, the freezing or cuts of public sector pay, declining purchasing power, pessimism about future developments and perceptions of bad governance. In this context, a new wave of protest has spread across Europe as a reaction to the austerity measures adopted during the economic crisis. Governments’ inability to deal with the crisis has generated in many places anxiety, which then turned into popular anger. People who have been hard hit by the crisis placed most of the blame with incumbent governments and condemned the corruption and lack of political responsibility of the political class in general.

In the preface to "Predicting Outdoor Sound," the authors say they regard their book as complementary to the book, "Computational Acoustics," by Erik M. Salomons. Further, they say that workers in outdoor sound would be wise to own both books. With these statements in mind, it seems prudent to briefly compare the two books. Put simply, "Computational Acoustics" is mainly about using full-wave, numerical models to predict long-range sound propagation in a realistic atmosphere over irregular, but otherwise simple, terrain. In contrast, "Predicting Outdoor Sound" is mainly about how to predict sound propagation in a homogeneous atmosphere over surfaces that range from simple flat impedance planes to very complex structures such as realistic barriers and buildings. There are other important differences as well. While "Computational Acoustics" is largely theoretical, "Predicting Outdoor Sound" has a wealth of experimental measurements and empirical prediction schemes. Specifically, Chapters 1-6 contain in-depth discussions of propagation in a homogeneous atmosphere over a flat, finite impedance surface. A multitude of ground impedance measurements and models are discussed in these chapters. Chapter 7 discusses the effect of source motion. Chapter 8 considers sound propagation over a flat surface with a horizontally varying impedance. Chapters 9 and 10 discuss, respectively, the performance of outdoor noise barriers and the effects of vegetation, trees and turbulence. Chapter 11 considers approximate analytic models for sound propagation that include the effects of a finite impedance surface, refraction, and turbulence. In Chapter 12, a number of currently popular, semi-empirical noise prediction schemes are discussed. Chapter 13, the final chapter, discusses sound and noise in an urban environment, with consideration of such issues as street canyons and building facades. Although the book probably would not serve well as a stand-alone text, the authors have nevertheless
On Number of Compositions of Natural Numbers

We first give a combinatorial interpretation of coefficients of Chebyshev polynomials, which allows us to connect them with compositions of natural numbers. Then we describe a relationship between the number of compositions of a natural number in which a certain number of parts are p-1, and other parts are not less than p with compositions in which all parts are not less than p. Then we find a relationship between principal minors of a type of Hessenberg matrices and compositions of natural numbers.

Parameterizing by the Number of Numbers
Fellows, Michael R; Rosamond, Frances A
2010-01-01
The usefulness of parameterized algorithmics has often depended on what Niedermeier has called, "the art of problem parameterization". In this paper we introduce and explore a novel but general form of parameterization: the number of numbers. Several classic numerical problems, such as Subset Sum, Partition, 3-Partition, Numerical 3-Dimensional Matching, and Numerical Matching with Target Sums, have multisets of integers as input. We initiate the study of parameterizing these problems by the number of distinct integers in the input. We rely on an FPT result for ILPF to show that all the above-mentioned problems are fixed-parameter tractable when parameterized in this way. In various applied settings, problem inputs often consist in part of multisets of integers or multisets of weighted objects (such as edges in a graph, or jobs to be scheduled). Such number-of-numbers parameterized problems often reduce to subproblems about transition systems of various kinds, parameterized by the size of the system descripti...
Obtaining the Dewey Decimal Classification Number from other databases: a catalog clean-up project
Directory of Open Access Journals (Sweden)
Stefano Bargioni
2013-07-01
Full Text Available The increasing availability of online catalogs and bibliographical databases allows not only for copy cataloging, but also for the retrieval of atomic information useful within the catalog. To this end, Dewey decimal numbers were imported from national and international sources by means of the unique identifier ISBN. Technical specifications have been developed to locate the records to be retrieved, to query external databases, to extract the Dewey decimal classification numbers and add them to the catalog. The exceptionally large amount of Dewey numbers added to the catalog has improved the semantic usability of the OPAC. The procedure established has also facilitated the collection of information on the use of the Dewey Decimal System in the various databases used and allowed to make certain comparisons between them. The tools employed can be used analogously for data-retrieval operations in the catalog, as an aid in the cataloging process, or to improve the OPAC in either a static or dynamic manner. Taking into account its virtually exclusive practical purpose, this work is characterized by practical rather than theoretical choices. However, the experience acquired opens up areas even in the field of academic research.

A new kind of numbers called Hyper Space Complex Numbers and its algebras are defined and proved. It is with good properties as the classic Complex Numbers, such as expressed in coordinates, triangular and exponent forms and following the associative and commutative laws of addition and multiplication. So the classic Complex Number is developed from in complex plane with two dimensions to in complex space with N dimensions and the number system is enlarged also.

Number systems-such as the natural numbers, integers, rationals, reals, or complex numbers-play a foundational role in mathematics, but these systems can present difficulties for students. In the studies reported here, we probed the boundaries of people's concept of a number system by asking them whether "number lines" of varying shapes qualify as possible number systems. In Experiment 1, participants rated each of a set of number lines as a possible number system, where the number lines differed in their structures (a single straight line, a step-shaped line, a double line, or two branching structures) and in their boundedness (unbounded, bounded below, bounded above, bounded above and below, or circular). Participants also rated each of a group of mathematical properties (e.g., associativity) for its importance to number systems. Relational properties, such as associativity, predicted whether participants believed that particular forms were number systems, as did the forms' ability to support arithmetic operations, such as addition. In Experiment 2, we asked participants to produce properties that were important for number systems. Relational, operation, and use-based properties from this set again predicted ratings of whether the number lines were possible number systems. In Experiment 3, we found similar results when the number lines indicated the positions of the individual numbers. The results suggest that people believe that number systems should be well-behaved with respect to basic arithmetic operations, and that they reject systems for which these operations produce ambiguous answers. People care much less about whether the systems have particular numbers (e.g., 0) or sets of numbers (e.g., the positives).

The technical difficulties of algebraic number theory often make this subject appear difficult to beginners. This undergraduate textbook provides a welcome solution to these problems as it provides an approachable and thorough introduction to the topic. Algebraic Number Theory takes the reader from unique factorisation in the integers through to the modern-day number field sieve. The first few chapters consider the importance of arithmetic in fields larger than the rational numbers. Whilst some results generalise well, the unique factorisation of the integers in these more general number fields often fail. Algebraic number theory aims to overcome this problem. Most examples are taken from quadratic fields, for which calculations are easy to perform. The middle section considers more general theory and results for number fields, and the book concludes with some topics which are more likely to be suitable for advanced students, namely, the analytic class number formula and the number field sieve. This is the fi...
All square chiliagonal numbers
Aṣiru, Muniru A.
2016-10-01
A square chiliagonal number is a number which is simultaneously a chiliagonal number and a perfect square (just as the well-known square triangular number is both triangular and square). In this work, we determine which of the chiliagonal numbers are perfect squares and provide the indices of the corresponding chiliagonal numbers and square numbers. The study revealed that the determination of square chiliagonal numbers naturally leads to a generalized Pell equation x2 - Dy2 = N with D = 1996 and N = 9962, and has six fundamental solutions out of which only three yielded integer values for use as indices of chiliagonal numbers. The crossing/independent recurrence relations satisfied by each class of indices of the corresponding chiliagonal numbers and square numbers are obtained. Finally, the generating functions serve as a clothesline to hang up the indices of the corresponding chiliagonal numbers and square numbers for easy display and this was used to obtain the first few sequence of square chiliagonal numbers.

A natural number $n$ is called {\\it multiperfect} or {\\it$k$-perfect} for integer $k\\ge2$ if $\\sigma(n)=kn$, where $\\sigma(n)$ is the sum of the positive divisors of $n$. In this paper, we establish the structure theorem of odd multiperfect numbers analogous as Euler's theorem on odd perfect numbers. We prove the divisibility of the Euler part of odd multiperfect numbers and characterize the forms of odd perfect numbers $n=\\pi^\\alpha M^2$ such that $\\pi\\equiv\\alpha(\\text{mod}8)$. We also present some examples to show the nonexistence of odd perfect numbers as applications.

We point out that the recursive formula that appears in Erickson's presentation "Fusible Numbers" is incorrect, and pose an alternate conjecture about the structure of fusible numbers. Although we are unable to solve the conjecture, we succeed in establishing some basic properties of fusible numbers. We suggest some possible approaches to the conjecture, and list further problems in the final chapter.

This textbook effectively builds a bridge from basic number theory to recent advances in applied number theory. It presents the first unified account of the four major areas of application where number theory plays a fundamental role, namely cryptography, coding theory, quasi-Monte Carlo methods, and pseudorandom number generation, allowing the authors to delineate the manifold links and interrelations between these areas. Number theory, which Carl-Friedrich Gauss famously dubbed the queen of mathematics, has always been considered a very beautiful field of mathematics, producing lovely results and elegant proofs. While only very few real-life applications were known in the past, today number theory can be found in everyday life: in supermarket bar code scanners, in our cars’ GPS systems, in online banking, etc. Starting with a brief introductory course on number theory in Chapter 1, which makes the book more accessible for undergraduates, the authors describe the four main application areas in Chapters...
Public knowledge and public trust.
Cunningham-Burley, Sarah
2006-01-01
As health care applications derived from human genetics research are likely to move increasingly from 'clinic to community', there is growing interest not just in how patients understand and take up health-related genetic information but also in the views of the wider population, as well as a range of professional groups. In this paper, issues relating public knowledge and public trust are raised and discussed in an attempt to move forward debates about public involvement in genomic research and the role of sociologists within interdisciplinary teams. As the field of public understanding of science has developed, we have seen a shift from a focus on the lack of scientific literacy as problem to a recognition of the range of different knowledges that people have and use as they confront science and technology in their everyday lives. As a mood for dialogue pervades many institutions in their relations with 'publics', attention must now be paid to the way in which knowledge and expertise is expressed, heard and acted upon in dialogic encounters. There is increasing concern about public trust in science and calls to increase public confidence, particularly through more open engagement with a range of publics. However, lack of trust or loss of confidence may be constructed as problems rather than reflecting empirical reality, where more complex relationships and attitudes prevail. Lack of trust is often privatized, deeply rooted in lived experience and routinely managed. Trust relations are generally characterized by ambivalence, uncertainty and risk, and are always provisional. Drawing on selected literature and empirical research to review and illustrate this field, this paper argues that scepticism or ambivalence on the part of publics are not necessarily problems to be overcome in the interest of scientific progress, but rather should be mobilized to enhance open and public debates about the nature and direction of genomics research, medicine, and the related

"Generalized numbers" is a multiplicative structure introduced by A. Beurling to study how independent prime number theory is from the additivity of the natural numbers. The results and techniques of this theory apply to other systems having the character of prime numbers and integers; for example, it is used in the study of the prime number theorem (PNT) for ideals of algebraic number fields. Using both analytic and elementary methods, this book presents many old and new theorems, including several of the authors' results, and many examples of extremal behavior of g-number systems. Also, the authors give detailed accounts of the L^2 PNT theorem of J. P. Kahane and of the example created with H. L. Montgomery, showing that additive structure is needed for proving the Riemann hypothesis. Other interesting topics discussed are propositions "equivalent" to the PNT, the role of multiplicative convolution and Chebyshev's prime number formula for g-numbers, and how Beurling theory provides an interpretation of the ...

Number and geometry are the foundations upon which mathematics has been built over some 3000 years. This book is concerned with the logical foundations of number systems from integers to complex numbers. The author has chosen to develop the ideas by illustrating the techniques used throughout mathematics rather than using a self-contained logical treatise. The idea of proof has been emphasised, as has the illustration of concepts from a graphical, numerical and algebraic point of view. Having laid the foundations of the number system, the author has then turned to the analysis of infinite proc

Numbers are fascinating. The fascination begins in childhood, when we first learn to count. It continues as we learn arithmetic, algebra, geometry, and so on. Eventually, we learn that numbers not only help us to measure the world, but also to understand it and, to some extent, to control it. In The Adventure of Numbers, Gilles Godefroy follows the thread of our expanding understanding of numbers to lead us through the history of mathematics. His goal is to share the joy of discovering and understanding this great adventure of the mind. The development of mathematics has been punctuated by a n

In a model in which quarks and leptons are built up from two spin 1/2 preons as fundamental entities, a new class of fermionic bound states (hyperquarks) arises. It turns out that these hyperquarks are necessary to fulfill the 't Hooft anomaly constraint, which then links the number of fermionic generations to the number of colors and hypercolors.

Full Text Available In today’s technology savvy world, computer security holds a prime importance. Most computer security algorithms require some amount of random data for generating public and private keys, session keys or for other purposes. Random numbers are those numbers that occur in a sequence such that the future value of the sequence cannot be predicted based on present or past values. Random numbers find application in statistical analysis and probability theory. The many applications of randomness have led to the development of random number generating algorithms. These algorithms generate a sequence of random numbers either computationally or physically. In our proposed technique, we have implemented a random number generation algorithm combining two existing random number generation techniques viz. Mid square method and Linear Congruential Generator

Ethics in Online Publications.
Vervaart, Peter
2014-10-01
Journals have been publishing the results of scientific investigations since the founding of Philosophical Transactions in 1665. Since then we have witnessed a massive expansion in the number of journals to the point that there are now approximately 28,000 active, peer reviewed journals collectively publishing more than 1.8 million articles per year. Before the mid-1990s, these journals were only available on paper but by the end of the 20th century, most journals had moved to online platforms. Online publication has also served as the impetus for the move to 'open-access' to the information contained in journals. The fact that a publication is 'on-line' and 'open-access' does not negate the responsibility of the author and the publisher to publish in an ethical way. [1] The document produced by the IFCC Ethics Task Force (TF-E) on publication ethics states that 'Ethics in Science at its broadest level encompasses research ethics, medical ethics, publication ethics, conflicts of interest, ethical responsibilities as educator, plus many other areas.' Thus publication ethics is a continuum from the first step of research design through to the information being read by the reader. In general terms 'publication ethics' includes the ethical behaviour of the authors in writing and submitting a scientific manuscript to a publisher for the purpose of publication, thus any discussion of publication ethics must include the role of the authors, referees, publisher and reader and the issues of authorship (and the use of 'ghosts'), plagiarism, duplicate publication (including in different languages), image manipulation (particularly in the era of digitisation), and conflict of interest [2]. To aid the authors, and others involved in the process of publication, a number of resources are now available particularly those from the Committee on Publication Ethics (COPE) [3] and the World Association of Medical Editors (WAME) [4]. More recently the issue of 'publisher ethics' has

Humans show a remarkable tendency to describe and think of numbers as being placed on a mental number line (MNL), with smaller numbers located on the left and larger ones on the right. Faster responses to small numbers are indeed performed on the left side of space, while responses to large numbers are facilitated on the right side of space (spatial-numerical association of response codes, SNARC effect). This phenomenon is considered the experimental demonstration of the MNL and has been extensively replicated throughout a variety of paradigms. Nevertheless, the majority of previous literature has mainly investigated this effect by means of response times and accuracy, whereas studies considering more subtle and automatic measures such as kinematic parameters are rare (e.g., in a reaching-to-grasp movement, the grip aperture is enlarged in responding to larger numbers than in responding to small numbers). In this brief review we suggest that numerical magnitude can also affect the what and how of action execution (i.e., temporal and spatial components of movement). This evidence could have large implications in the strongly debated issue concerning the effect of experience and culture on the orientation of MNL.

This is a book about numbers and how those numbers are represented in and operated on by computers. It is crucial that developers understand this area because the numerical operations allowed by computers, and the limitations of those operations, especially in the area of floating point math, affect virtually everything people try to do with computers. This book aims to fill this gap by exploring, in sufficient but not overwhelming detail, just what it is that computers do with numbers. Divided into two parts, the first deals with standard representations of integers and floating point numb

We propose a simple real-valued generalization of the well known integer-valued Erdos number as a topological, non-metric measure of the `closeness' felt between two nodes in an undirected, weighted graph. These real-valued Erdos numbers are asymmetric and are able to distinguish between network topologies that standard distance metrics view as identical. We use this measure to study some simple analytically tractable networks, and show the utility of our measure to devise a ratings scheme based on the generalized Erdos number that we deploy on the data from the NetFlix prize, and find a significant improvement in our ratings prediction over a baseline.
Professor Stewart's incredible numbers
Stewart, Ian
2015-01-01
Ian Stewart explores the astonishing properties of numbers from 1 to10 to zero and infinity, including one figure that, if you wrote it out, would span the universe. He looks at every kind of number you can think of - real, imaginary, rational, irrational, positive and negative - along with several you might have thought you couldn't think of. He explains the insights of the ancient mathematicians, shows how numbers have evolved through the ages, and reveals the way numerical theory enables everyday life. Under Professor Stewart's guidance you will discover the mathematics of codes,

This book presents detailed studies of the development of three kinds of number. In the first part the development of the natural numbers from Stone-Age times right up to the present day is examined not only from the point of view of pure history but also taking into account archaeological, anthropological and linguistic evidence. The dramatic change caused by the introduction of logical theories of number in the 19th century is also treated and this part ends with a non-technical account of the very latest developments in the area of Gödel's theorem. The second part is concerned with the deve

The world around us is saturated with numbers. They are a fundamental pillar of our modern society, and accepted and used with hardly a second thought. But how did this state of affairs come to be? In this book, Leo Corry tells the story behind the idea of number from the early days of the Pythagoreans, up until the turn of the twentieth century. He presents an overview of how numbers were handled and conceived in classical Greek mathematics, in the mathematics of Islam, in European mathematics of the middle ages and the Renaissance, during the scientific revolution, all the way through to the

Careful organization and clear, detailed proofs characterize this methodical, self-contained exposition of basic results of classical algebraic number theory from a relatively modem point of view. This volume presents most of the number-theoretic prerequisites for a study of either class field theory (as formulated by Artin and Tate) or the contemporary treatment of analytical questions (as found, for example, in Tate's thesis).Although concerned exclusively with algebraic number fields, this treatment features axiomatic formulations with a considerable range of applications.

Full Text Available We introduce, generate and study a family of supersymmetric displaced number states (SDNS that can be considered generalized coherent states of the supersymmetric harmonic oscillator. The family is created from the seminal supersymmetric boson-fermion entangling annihilation operator introduced by Aragone and Zypman and later expanded by Kornbluth and Zypman. Using the momentum representation, the states are obtained analytically in compact form as displaced supersymmetric number states. We study their position-momentum uncertainties, and their bunchiness by classifying them according to their Mandel Q-parameter in phase space. We were also able to find closed form analytical representations in the space and number basis.

Quantum random number generator
Pooser, Raphael C.
2016-05-10
A quantum random number generator (QRNG) and a photon generator for a QRNG are provided. The photon generator may be operated in a spontaneous mode below a lasing threshold to emit photons. Photons emitted from the photon generator may have at least one random characteristic, which may be monitored by the QRNG to generate a random number. In one embodiment, the photon generator may include a photon emitter and an amplifier coupled to the photon emitter. The amplifier may enable the photon generator to be used in the QRNG without introducing significant bias in the random number and may enable multiplexing of multiple random numbers. The amplifier may also desensitize the photon generator to fluctuations in power supplied thereto while operating in the spontaneous mode. In one embodiment, the photon emitter and amplifier may be a tapered diode amplifier.

Random numbers are a fundamental resource in science and engineering with important applications in simulation and cryptography. The inherent randomness at the core of quantum mechanics makes quantum systems a perfect source of entropy. Quantum random number generation is one of the most mature quantum technologies with many alternative generation methods. This review discusses the different technologies in quantum random number generation from the early devices based on radioactive decay to the multiple ways to use the quantum states of light to gather entropy from a quantum origin. Randomness extraction and amplification and the notable possibility of generating trusted random numbers even with untrusted hardware using device-independent generation protocols are also discussed.

Distance decay and Voronoi graph were applied to assess population size, area and number of people per unit area that green space serves in Harbin based on CIS map and field research. And the distribution of public parks in Harbin was evaluated. Result shows that the Wetland Park, lilac Park, Sports Park serve less than 300 people per hectare, and they develop well. Landscape Square, Lesong Square, Cnangqing Park, Jianguo Park, Qingbin Park, Taiping Park, and Shangzhi Park serve more than 40 000 people per hectare. Those parks cannot meet the needs of inhabitants. Three recommendations are put forward: to establish new public parks in some places in Harbin, increase investment in construction and maintenance of infrastructure in public parks, and to establish new public parks in the suburbs.%将哈尔滨市2009年GIS图和实地调研相结合,运用距离衰减和Voronoi图分析方法估计了哈尔滨城市公园绿地的服务总人数、面积及单位面积服务的人数,并对哈尔滨城市公园绿地布局进行了分析评价.结果表明:湿地公园、丁香公园、体育公园每公顷服务人数均小于300人,公园绿地发展良好；开发区景观广场、乐松广场、长青公园、建国公园、清滨公园、太平公园,尚志公园每公顷面积服务人数均已超过40 000人,无法满足周围游人的需要.根据研究结果提出了3点建议:局部地段建立新的公园绿地；加强对公园基础服务设施的建设和养护资金的投入；在郊区建立新的公园.

Full Text Available The topic of this issue is PUBLIC SPACES. It is familiar and clear to every citizen. The streets and courtyards as childhood experiences remain with us forever. And these are the places where we come with our parents at weekends, where we meet friends, where we have dates and where we already come for a walk with our children.The history of public spaces is long and captivating. It was the main city squares where the most important events took place in history. The Agoras of Ancient Greece and the Roman Forums, the squares of Vatican, Paris and London, Moscow and Saint Petersburg… Greve, Trafalgar, Senate, Palace, Red, Bolotnaya – behind every name there is life of capitals, countries and nations.Public spaces, their shapes, image and development greatly influence the perception of the city as a whole. Both visitors and inhabitants can see in public spaces not only the visage but the heart, the soul and the mind of the city.Unfortunately, sometimes we have to prove the value of public spaces and defend them from those who consider them nothing but a blank space, nobody’s land destined for barbarous development.What should happen to make citizens perceive public spaces as their own and to make authorities consider development and maintenance of squares and parks their priority task against the background of increasing competition between cities and the fight for human capital? Lately they more often say about “a high-quality human capital”. And now, when they say “the city should be liveable” they add “for all groups of citizens, including the creative class”.

Full Text Available The present study reports chromosome numbers of 17 species of Bromeliaceae, belonging to the genera Encholirium, Bromelia, Orthophytum, Hohenbergia, Billbergia, Neoglaziovia, Aechmea, Cryptanthus and Ananas. Most species present 2n = 50, however, Bromelia laciniosa, Orthophytum burle-marxii and O. maracasense are polyploids with 2n = 150, 2n = 100 and 2n = 150, respectively, while for Cryptanthus bahianus, 2n = 34 + 1-4B. B chromosomes were observed in Bromelia plumieri and Hohenbergia aff. utriculosa. The chromosome number of all species was determined for the first time, except for Billbergia chlorosticta and Cryptanthus bahianus. Our data supports the hypothesis of a basic number of x = 25 for the Bromeliaceae family and decreasing aneuploidy in the genus Cryptanthus.
Quantum random number generation

Quantum physics can be exploited to generate true random numbers, which have important roles in many applications, especially in cryptography. Genuine randomness from the measurement of a quantum system reveals the inherent nature of quantumness—coherence, an important feature that differentiates quantum mechanics from classical physics. The generation of genuine randomness is generally considered impossible with only classical means. On the basis of the degree of trustworthiness on devices, quantum random number generators (QRNGs) can be grouped into three categories. The first category, practical QRNG, is built on fully trusted and calibrated devices and typically can generate randomness at a high speed by properly modelling the devices. The second category is self-testing QRNG, in which verifiable randomness can be generated without trusting the actual implementation. The third category, semi-self-testing QRNG, is an intermediate category that provides a tradeoff between the trustworthiness on the device and the random number generation speed.

Earthquake number forecasts testing
Kagan, Yan Y.
2017-10-01
We study the distributions of earthquake numbers in two global earthquake catalogues: Global Centroid-Moment Tensor and Preliminary Determinations of Epicenters. The properties of these distributions are especially required to develop the number test for our forecasts of future seismic activity rate, tested by the Collaboratory for Study of Earthquake Predictability (CSEP). A common assumption, as used in the CSEP tests, is that the numbers are described by the Poisson distribution. It is clear, however, that the Poisson assumption for the earthquake number distribution is incorrect, especially for the catalogues with a lower magnitude threshold. In contrast to the one-parameter Poisson distribution so widely used to describe earthquake occurrences, the negative-binomial distribution (NBD) has two parameters. The second parameter can be used to characterize the clustering or overdispersion of a process. We also introduce and study a more complex three-parameter beta negative-binomial distribution. We investigate the dependence of parameters for both Poisson and NBD distributions on the catalogue magnitude threshold and on temporal subdivision of catalogue duration. First, we study whether the Poisson law can be statistically rejected for various catalogue subdivisions. We find that for most cases of interest, the Poisson distribution can be shown to be rejected statistically at a high significance level in favour of the NBD. Thereafter, we investigate whether these distributions fit the observed distributions of seismicity. For this purpose, we study upper statistical moments of earthquake numbers (skewness and kurtosis) and compare them to the theoretical values for both distributions. Empirical values for the skewness and the kurtosis increase for the smaller magnitude threshold and increase with even greater intensity for small temporal subdivision of catalogues. The Poisson distribution for large rate values approaches the Gaussian law, therefore its skewness

Our knowledge of the long-term evolution of solar activity and of its primary modulation, the 11-year cycle, largely depends on a single direct observational record: the visual sunspot counts that retrace the last 4 centuries, since the invention of the astronomical telescope. Currently, this activity index is available in two main forms: the International Sunspot Number initiated by R. Wolf in 1849 and the Group Number constructed more recently by Hoyt and Schatten (1998a,b). Unfortunately, those two series do not match by various aspects, inducing confusions and contradictions when used in crucial contemporary studies of the solar dynamo or of the solar forcing on the Earth climate. Recently, new efforts have been undertaken to diagnose and correct flaws and biases affecting both sunspot series, in the framework of a series of dedicated Sunspot Number Workshops. Here, we present a global overview of our current understanding of the sunspot number calibration. While the early part of the sunspot record befor...

We investigate the "law of small numbers" using a unique panel data set on lotto gambling. Because we can track individual players over time, we can measure how they react to outcomes of recent lotto drawings. We can therefore test whether they behave as if they believe they can predict lotto
Number theory III Diophantine geometry
1991-01-01
From the reviews of the first printing of this book, published as Volume 60 of the Encyclopaedia of Mathematical Sciences: "Between number theory and geometry there have been several stimulating influences, and this book records of these enterprises. This author, who has been at the centre of such research for many years, is one of the best guides a reader can hope for. The book is full of beautiful results, open questions, stimulating conjectures and suggestions where to look for future developments. This volume bears witness of the broad scope of knowledge of the author, and the influence of several people who have commented on the manuscript before publication ... Although in the series of number theory, this volume is on diophantine geometry, and the reader will notice that algebraic geometry is present in every chapter. ... The style of the book is clear. Ideas are well explained, and the author helps the reader to pass by several technicalities. Reading and rereading this book I noticed that the topics ...

Full Text Available The necessary work for developing a scientific publication is sometimes underestimated and requires the effective participation of many players to obtain a result in good standard. Initially it depends upon the determination of the authors that decide to write the scientific article. Scientific writing is a very challenging and time consuming task, but at the same time essential for any scientist. A published scientific article is unquestionably one of the main indicators of scientific production, especially if published in a qualified scientific journal with highly qualified editorial committee and strict peer review procedure. By looking at evaluation criteria for scientific production of the several Thematic Scientific Committees of the Brazilian Council for Scientific and Technological Development (CNPq it becomes clear publications in scientific journals that has certified quality is the most important item in the evaluation of a scientist production.

This opinion-based article aims to highlight the worrying decline in support for dental public health as a specialty. Not only is this specialty important for its role in commissioning services, it is crucial for the identification of vulnerable groups in society and ensuring dental services are acceptable and assessable for these populations. Dental public health also addresses the social determinants of health in its approach, acknowledging the impact of these in perpetuating inequalities and looking for multisectoral approaches to their management. This article also looks at the lack of appreciation for these determinants in dental foundation training and how a change in the structure of the programme could both address this and the current shortage of places.

The social brain hypothesis predicts that humans have an average of about 150 relationships at any given time. Within this 150, there are layers of friends of an ego, where the number of friends in a layer increases as the emotional closeness decreases. Here we analyse a mobile phone dataset, firstly, to ascertain whether layers of friends can be identified based on call frequency. We then apply different clustering algorithms to break the call frequency of egos into clusters and compare the number of alters in each cluster with the layer size predicted by the social brain hypothesis. In this dataset we find strong evidence for the existence of a layered structure. The clustering yields results that match well with previous studies for the innermost and outermost layers, but for layers in between we observe large variability.

Private and public patients in public hospitals in Australia.
Shmueli, Amir; Savage, Elizabeth
2014-04-01
The nature of the private-public mix in health insurance and in health care is a major issue in most health systems. To compare the hospitalization characteristics of private and public patients hospitalized in public hospitals. We focused on planned, overnight and same-day admissions, discharged during 2004-2005 from the public New South Wales hospitals, and run fixed-effects regressions in order to identify the effect of accommodation status (private/public) on the hospitalization characteristics. Private patients have one third less waiting days than public patients, and they are assigned higher urgency of admission. Length of stay and length of visit are both unrelated to the accommodation status, however, private patients tend to have more hours in ICU and more procedures performed during the hospitalization. In-hospital mortality and the number of transfers (wards) are not affected by the accommodation status. Private patients are treated differently than public patients in public hospitals, reinforcing the private health insurance-related inequity in inpatient care identified by others. Two health policy issues emerge from the findings: the role of private health insurance in the Australian socialized medicine system, and in particular, in the public hospitals; and the way public hospitals are reimbursed for private patients.

The 'Number Needed to Treat' (NNT) is a useful measure for estimating the number of patients that would need to receive a therapeutic intervention to avoid one of the adverse events that the treatment is designed to prevent. We explored the possibility of an adaption of NNT to estimate the 'Number Needed to $ave' (NN$) as a new, conceptual systems metric to estimate potential cost-savings to the health system from implementation of a treatment, or in this case, a program. We used the outcomes of the INSPIRED COPD Outreach ProgramTM to calculate that 26 patients would need to complete the program to avoid healthcare expenditures of $100,000, based on hospital bed days avoided. The NN$ does not translate into 'cost savings' per se, but redirection of resource expenditures for other purposes. We propose that the NN$ metric, if further developed, could help to inform system-level resource allocation decisions in a manner similar to the way that the NNT metric helps to inform individual-level treatment decisions.
Topics from the theory of numbers
Grosswald, Emil
1984-01-01
Many of the important and creative developments in modern mathematics resulted from attempts to solve questions that originate in number theory. The publication of Emil Grosswald’s classic text presents an illuminating introduction to number theory. Combining the historical developments with the analytical approach, Topics from the Theory of Numbers offers the reader a diverse range of subjects to investigate, including: * divisibility * congruences * the Riemann zeta function * Diophantine equations and Fermat’s conjecture * the theory of partitions Comprehensive in nature, Topics from the Theory of Numbers is an ideal text for advanced undergraduates and graduate students alike. "In my opinion it is excellent. It is carefully written and represents clearly a work of a scholar who loves and understands his subject. One can only wish more authors would take such pains and would be as good and honest expositors as Grosswald." — Marc Kac "This book is designed for use in a first course in number theory at...

2017-07-01
Timely publication of data is important for the medical community and provides a valuable contribution to data disclosure. The objective of this study was to identify and evaluate times to acceptance and publication for peer-reviewed manuscripts, reviews, and letters to the editor. Key publication metrics for published manuscripts, reviews, and letters to the editor were identified by eight Amgen publications professionals. Data for publications submitted between 1 January 2013 and 1 November 2015 were extracted from a proprietary internal publication-tracking database. Variables included department initiating the study, publication type, number of submissions per publication, and the total number of weeks from first submission to acceptance, online publication, and final publication. A total of 337 publications were identified, of which 300 (89%) were manuscripts. Time from submission to acceptance and publication was generally similar between clinical and real-world evidence (e.g. observational and health economics studies) publications. Median (range) time from first submission to acceptance was 23.4 (0.2-226.2) weeks. Median (range) time from first submission to online (early-release) publication was 29.7 (2.4-162.6) weeks. Median (range) time from first submission to final (print) publication was 36.2 (2.8-230.8) weeks. Time from first submission to acceptance, online publication, and final publication increased accordingly with number of submissions required for acceptance, with similar times noted between each subsequent submission. Analysis of a single-company publication database showed that the median time for manuscripts to be fully published after initial submission was 36.2 weeks, and time to publication increased accordingly with the number of submissions. Causes for multiple submissions and time from clinical trial completion to first submission were not assessed; these were limitations of the study. Nonetheless, publication planners should consider

We suggest that baryon-number conservation may not be absolute and that an integrally charged quark may disintegrate into two leptons and an antilepton with a coupling strength G Bmp2≲ 10-9. On the other hand, if quarks are much heavier than low-lying hadrons, the decay of a three-quark system like the proton is highly forbidden (proton lifetime ≳ 1028 y). Motivation for these ideas appears to arise within a unified theory of hadrons and leptons and their gauge interactions. We emphasize the consequences of such a possibility for real quark searches.

Quantum random number generator
Stipcevic, M
2006-01-01
We report upon a novel principle for realization of a fast nondeterministic random number generator whose randomness relies on intrinsic randomness of the quantum physical processes of photonic emission in semiconductors and subsequent detection by the photoelectric effect. Timing information of detected photons is used to generate binary random digits-bits. The bit extraction method based on restartable clock theoretically eliminates both bias and autocorrelation while reaching efficiency of almost 0.5 bits per random event. A prototype has been built and statistically tested.

[Public health education in Austria. An overview].
Diem, Günter; Dorner, Thomas Ernst
2014-04-01
The future challenges for the Austrian health care system require an increasing number of public health experts of different professions in all fields of public health. In this article the offer of public health education in Austrian universities and universities for applied sciences was searched based on the predominantly online available information on web platforms of the schools. Currently (2013), there are three postgraduate public health university courses and two public health doctoral programs in Austria. Additionally, 34 degree programmes could be identified, in which parts of public health are covered. But also in medical curricula at Austrian medical schools, public health contents have found their place. In Austria, there is already a multifaceted offer for public health education. However, to build an appropriate public health work force, capable to manage the public health challenges in all its dimensions in terms of health in all policies, this offer should still be intensified.

Full Text Available Cryptography, the secret writing, is probably same old as writing itself and has applications in data security insurance. There are cryptosystems where the encipher algorithm can be public. These are public key algorithms. Research on public key algorithms has been concerned with security aspects. The results of this research have induced sufficient confidence to apply public key cryptography a larger scale. The most used and checked public key-based cryptosystem was find by Rivest, Shamir and Adleman, so called RSA system. This paper shows the RSA algorithm. We have realised a program that is able to determine prime numbers with over 100 digits and compute RSA system parameters.

Can a resident's publication record predict fellowship publications?
Directory of Open Access Journals (Sweden)
Vinay Prasad
Full Text Available BACKGROUND: Internal medicine fellowship programs have an incentive to select fellows who will ultimately publish. Whether an applicant's publication record predicts long term publishing remains unknown. METHODS: Using records of fellowship bound internal medicine residents, we analyzed whether publications at time of fellowship application predict publications more than 3 years (2 years into fellowship and up to 7 years after fellowship match. We calculate the sensitivity, specificity, positive and negative predictive values and likelihood ratios for every cutoff number of application publications, and plot a receiver operator characteristic curve of this test. RESULTS: Of 307 fellowship bound residents, 126 (41% published at least one article 3 to 7 years after matching, and 181 (59% of residents do not publish in this time period. The area under the receiver operator characteristic curve is 0.59. No cutoff value for application publications possessed adequate test characteristics. CONCLUSION: The number of publications an applicant has at time of fellowship application is a poor predictor of who publishes in the long term. These findings do not validate the practice of using application publications as a tool for selecting fellows.

Beyond natural numbers: negative number representation in parietal cortex.
Blair, Kristen P; Rosenberg-Lee, Miriam; Tsang, Jessica M; Schwartz, Daniel L; Menon, Vinod
2012-01-01
Unlike natural numbers, negative numbers do not have natural physical referents. How does the brain represent such abstract mathematical concepts? Two competing hypotheses regarding representational systems for negative numbers are a rule-based model, in which symbolic rules are applied to negative numbers to translate them into positive numbers when assessing magnitudes, and an expanded magnitude model, in which negative numbers have a distinct magnitude representation. Using an event-related functional magnetic resonance imaging design, we examined brain responses in 22 adults while they performed magnitude comparisons of negative and positive numbers that were quantitatively near (difference 6). Reaction times (RTs) for negative numbers were slower than positive numbers, and both showed a distance effect whereby near pairs took longer to compare. A network of parietal, frontal, and occipital regions were differentially engaged by negative numbers. Specifically, compared to positive numbers, negative number processing resulted in greater activation bilaterally in intraparietal sulcus (IPS), middle frontal gyrus, and inferior lateral occipital cortex. Representational similarity analysis revealed that neural responses in the IPS were more differentiated among positive numbers than among negative numbers, and greater differentiation among negative numbers was associated with faster RTs. Our findings indicate that despite negative numbers engaging the IPS more strongly, the underlying neural representation are less distinct than that of positive numbers. We discuss our findings in the context of the two theoretical models of negative number processing and demonstrate how multivariate approaches can provide novel insights into abstract number representation.

Full Text Available The publication Corporate Fraud and Internal Control contains essential guidance for companies to examine and improve their fraud programs: Corporate governance legislation has become increasingly concerned with the ongoing resilience of organizations and, particularly, with their ability to resist corporate fraud from the lowest levels to the upper echelons of executive management. It has become unacceptable for those responsible for corporate governance to claim, "I didn't know". Corporate Fraud and Internal Control focuses on the appropriateness of the design of the system of internal controls in fraud risk mitigation, as well as the mechanisms to ensure effective implementation and monitoring on an ongoing basis.
Lepton family number violation
Energy Technology Data Exchange (ETDEWEB)
Herczeg, P.
1999-03-01
At present there is evidence from neutrino oscillation searches that the neutrinos are in fact massive particles and that they mix. If confirmed, this would imply that the conservation of LFN is not exact. Lepton family number violation (LFNV) has been searched for with impressive sensitivities in many processes involving charged leptons. The present experimental limits on some of them (those which the author shall consider here) are shown in Table 1. These stringent limits are not inconsistent with the neutrino oscillation results since, given the experimental bounds on the masses of the known neutrinos and the neutrino mass squared differences required by the oscillation results, the effects of LFNV from neutrino mixing would be too small to be seen elsewhere (see Section 2). The purpose of experiments searching for LFNV involving the charged leptons is to probe the existence of other sources of LFNV. Such sources are present in many extensions of the SM. In this lecture the author shall discuss some of the possibilities, focusing on processes that require muon beams. Other LFNV processes, such as the decays of the kaons and of the {tau}, provide complementary information. In the next Section he shall consider some sources of LFNV that do not require an extension of the gauge group of the SM (the added leptons or Higgs bosons may of course originate from models with extended gauge groups). In Section 3 he discusses LFNV in left-right symmetric models. In Section 4 he considers LFNV in supersymmetric models, first in R-parity conserving supersymmetric grand unified models, and then in the minimal supersymmetric standard model with R-parity violation. The last section is a brief summary of the author`s conclusions.

In this paper we test the effect of non-binding defaults on the level of contribution to a public good. We manipulate the default numbers appearing on the decision screen to nudge subjects toward a free-rider strategy or a perfect conditional cooperator strategy. Our results show that the vast...... majority of our subjects did not adopt the default numbers, but their stated strategy was affected by the default. Moreover, we find that our manipulation spilled over to a subsequent repeated public goods game where default was not manipulated. Here we found that subjects who previously saw the free rider...
Beyond Natural Numbers: Negative Number Representation in Parietal Cortex
Blair, Kristen P.; Rosenberg-Lee, Miriam; Tsang, Jessica M.; Schwartz, Daniel L.; Menon, Vinod
2012-01-01
Unlike natural numbers, negative numbers do not have natural physical referents. How does the brain represent such abstract mathematical concepts? Two competing hypotheses regarding representational systems for negative numbers are a rule-based model, in which symbolic rules are applied to negative numbers to translate them into positive numbers when assessing magnitudes, and an expanded magnitude model, in which negative numbers have a distinct magnitude representation. Using an event-relate...

Access to emergency number services.
Harkins, Judith E; Strauss, Karen Peltz
2008-01-01
Access to emergency services is mandated by Title II of the Americans with Disabilities Act (ADA). The Department of Justice oversees the accessibility of public safety answering points (PSAPs), popularly called 9-1-1 centers. The Federal Communications Commission (FCC) has at least two roles in emergency number access: (1) as regulator of the ADA's Title IV on telecommunications access, and (2) as regulator of communications companies with regard to support of and interconnection with PSAPs. The rules of both agencies contributed significantly to the improvement during the 1990s of access to 9-1-1 for people who are deaf, hard of hearing, or speech disabled. However, as new technologies for text wireless communications and relay services have moved quickly to Internet protocol (IP)-based technologies over the past 5-8 years, the use of traditional wireline telephones and text telephones among deaf, hard of hearing, and speech-disabled people has declined. PSAPs cannot be contacted via the newer forms of telecommunications, such as e-mail, instant messaging, and IP-based forms of relay services, including video relay services. The gap between the technology supported by policy and the technologies currently being used by deaf and hard of hearing people has become a serious problem that is difficult to solve because of the separate jurisdictions of the two agencies, the need for coordination within the FCC, technological challenges, and funding issues. In this article, the key policy and technology challenges will be analyzed and recommendations made for short-and long-term solutions to this dilemma.

[Intel random number generator-based true random number generator].
Huang, Feng; Shen, Hong
2004-09-01
To establish a true random number generator on the basis of certain Intel chips. The random numbers were acquired by programming using Microsoft Visual C++ 6.0 via register reading from the random number generator (RNG) unit of an Intel 815 chipset-based computer with Intel Security Driver (ISD). We tested the generator with 500 random numbers in NIST FIPS 140-1 and X(2) R-Squared test, and the result showed that the random number it generated satisfied the demand of independence and uniform distribution. We also compared the random numbers generated by Intel RNG-based true random number generator and those from the random number table statistically, by using the same amount of 7500 random numbers in the same value domain, which showed that the SD, SE and CV of Intel RNG-based random number generator were less than those of the random number table. The result of u test of two CVs revealed no significant difference between the two methods. Intel RNG-based random number generator can produce high-quality random numbers with good independence and uniform distribution, and solves some problems with random number table in acquisition of the random numbers.

The selected perspective attempts here that of advancing through axiomatic descriptions.

Chronically understaffed public health laboratories depend on a decreasing number of employees who must assume broader responsibilities in order to sustain essential functions for the many clients the laboratories support. Prospective scientists considering a career in public health are often not aware of the requirements associated with working in a laboratory regulated by the Clinical Laboratory Improvement Amendments (CLIA). The purpose of this pilot internship was two-fold; introduce students to operations in a regulated laboratory early enough in their academics so that they could make good career decisions, and evaluate internship methodology as one possible solution to workforce shortages. Four interns were recruited from three different local universities, and were paired with an experienced State Laboratories Division (SLD) staff mentor. Students performed tasks that demonstrated the importance of CLIA regulations for 10–15 hours per week over a 14 week period. Students also attended several directed group sessions on regulatory lab practice and quality systems. Both interns and mentors were surveyed periodically during the semester. Surveys of mentors and interns indicated overall positive experiences. One-on-one pairing of experienced public health professionals and students seems to be a mutually beneficial arrangement. Interns reported that they would participate if the internship was lower paid, unpaid, or for credit only. The internship appeared to be an effective tool to expose students to employment in CLIA-regulated laboratories, and potentially help address public health laboratory staffing shortfalls. Longer term follow up with multiple classes of interns may provide a more informed assessment. PMID:23386992

Accelerating scientific publication in biology.
Vale, Ronald D
2015-11-03
Scientific publications enable results and ideas to be transmitted throughout the scientific community. The number and type of journal publications also have become the primary criteria used in evaluating career advancement. Our analysis suggests that publication practices have changed considerably in the life sciences over the past 30 years. More experimental data are now required for publication, and the average time required for graduate students to publish their first paper has increased and is approaching the desirable duration of PhD training. Because publication is generally a requirement for career progression, schemes to reduce the time of graduate student and postdoctoral training may be difficult to implement without also considering new mechanisms for accelerating communication of their work. The increasing time to publication also delays potential catalytic effects that ensue when many scientists have access to new information. The time has come for life scientists, funding agencies, and publishers to discuss how to communicate new findings in a way that best serves the interests of the public and the scientific community.

Prisoner reentry: a public health or public safety issue for social work practice?
Patterson, George T
2013-01-01
A significant literature identifies the policy, economic, health, and social challenges that confront released prisoners. This literature also describes the public health and public safety risks associated with prisoner reentry, provides recommendations for improving the reentry process, and describes the effectiveness of prison-based programs on recidivism rates. Public health and public safety risks are particularly significant in communities where large numbers of prisoners are released and few evidence-based services exist. The purpose of this article is to describe the public health and public safety risks that released prisoners experience when they reenter communities, and to discuss the social justice issues relevant for social work practice.

La investigación de Martínez Assad tuvo muchos méritos, aunque tal vez el mayor de ellos fue el hecho de analizar el movimiento de Saturnino Cedillo en sus aspectos económicos, sociales, políticos e ideológicos. Con la seriedad académica que siempre lo caracteriza, el ahora también Premio Nacional de Ciencias y Artes 2013 examinó los momentos más importantes en la vida del cacique potosino: su incursión en el torbellino revolucionario (1912, su apoyo al Plan de Agua Prieta (1920, su alianza con los gobiernos de Álvaro Obregón (1920-1924 y Plutarco Elías Calles (1924-1928, y su enfrentamiento final con el gobierno de Lázaro Cárdenas (1934-1940. De esta manera, Martínez Assad demostró que Cedillo, al rechazar el socialismo, las huelgas y el ejido, fue expuesto por el Estado cardenista —empeñado en lograr una centralización política y administrativa— como aliado de las compañías petroleras expropiadas el 18 de marzo de 1938 y portavoz del fascismo alemán en México
The concrete theory of numbers: initial numbers and wonderful properties of numbers repunit
Tarasov, Boris V
2007-01-01
In this work initial numbers and repunit numbers have been studied. All numbers have been considered in a decimal notation. The problem of simplicity of initial numbers has been studied. Interesting properties of numbers repunit are proved: $gcd(R_a, R_b) = R_{gcd(a,b)}$; $R_{ab}/(R_aR_b)$ is an integer only if $gcd(a,b) = 1$, where $a\\geq1$, $b\\geq1$ are integers. Dividers of numbers repunit, are researched by a degree of prime number.
THE RELATIONSHIP BETWEEN NUMBER NAMES AND NUMBER CONCEPTS
DEFF Research Database (Denmark)
Ejersbo, Lisser Rye; Misfeldt, Morten
2015-01-01
Different countries have different names for numbers. These names are often related in a regular way to the base-10 place value system used for writing numbers as digits. However, in several languages, this regularity breaks down (e.g., between 10 and 20), and there is limited knowledge of how...... the regularity or irregularity of number naming affects children’s formation of number concepts and arithmetic performance. We investigate this issue by reviewing relevant literature and undertaking a design research project addressing the specific irregularities of the Danish number names. In this project...

Risk communication: Uncertainties and the numbers game
Energy Technology Data Exchange (ETDEWEB)
Ortigara, M. [ed.
1995-08-30
The science of risk assessment seeks to characterize the potential risk in situations that may pose hazards to human health or the environment. However, the conclusions reached by the scientists and engineers are not an end in themselves - they are passed on to the involved companies, government agencies, legislators, and the public. All interested parties must then decide what to do with the information. Risk communication is a type of technical communication that involves some unique challenges. This paper first defines the relationships between risk assessment, risk management, and risk communication and then explores two issues in risk communication: addressing uncertainty and putting risk number into perspective.

The Mental Number Line in Dyscalculia: Impaired Number Sense or Access From Symbolic Numbers?
Lafay, Anne; St-Pierre, Marie-Catherine; Macoir, Joël
2016-03-25
Numbers may be manipulated and represented mentally over a compressible number line oriented from left to right. According to numerous studies, one of the primary reasons for dyscalculia is related to improper understanding of the mental number line. Children with dyscalculia usually show difficulty when they have to place Arabic numbers on a physical number line. However, it remains unclear whether they have a deficit with the mental number line per se or a deficit with accessing it from nonsymbolic and/or symbolic numbers. Quebec French-speaking 8- to 9-year-old children with (24) and without (37) dyscalculia were assessed with transcoding tasks (number-to-positionandposition-to-number) designed to assess the acuity of the mental number line with Arabic and spoken numbers as well as with analogic numerosities. Results showed that children with dyscalculia produced a larger percentage absolute error than children without mathematics difficulties in every task except the number-to-position transcoding task with analogic numerosities. Hence, these results suggested that children with dyscalculia do not have a general deficit of the mental number line but rather a deficit with accessing it from symbolic numbers.
Simple Remarks on Carmichael Numbers
Uchiyama, Shigenori
An odd composite number n for which an-1 ≡ 1 (mod n) for all integers a coprime to n is called a Carmichael number. This paper shows that some class of Carmichael numbers which have relatively large prime factors can be recognized in deterministic polynomial time under the assumption of the Extended Riemann Hypothesis (ERH). Also some related problems are discussed.

Cognitive representation of negative numbers.
Fischer, Martin H
2003-05-01
To understand negative numbers, must we refer to positive number representations (the phylogenetic hypothesis), or do we acquire a negative mental number line (the ontogenetic hypothesis)? In the experiment reported here, participants made lateralized button responses to indicate the larger of two digits from the range -9 to 9. Digit pairs were displayed spatially congruent or incongruent with either a phylogenetic or an ontogenetic mental number line. The pattern of decision latencies suggests that negative numbers become associated with left space, thus supporting the ontogenetic view.
Dengue disease, basic reproduction number and control
Rodrigues, Helena Sofia; Torres, Delfim F M; Zinober, Alan; 10.1080/00207160.2011.554540
2011-01-01
Dengue is one of the major international public health concerns. Although progress is underway, developing a vaccine against the disease is challenging. Thus, the main approach to fight the disease is vector control. A model for the transmission of Dengue disease is presented. It consists of eight mutually exclusive compartments representing the human and vector dynamics. It also includes a control parameter (insecticide) in order to fight the mosquito. The model presents three possible equilibria: two disease-free equilibria (DFE) and another endemic equilibrium. It has been proved that a DFE is locally asymptotically stable, whenever a certain epidemiological threshold, known as the basic reproduction number, is less than one. We show that if we apply a minimum level of insecticide, it is possible to maintain the basic reproduction number below unity. A case study, using data of the outbreak that occurred in 2009 in Cape Verde, is presented.
Quantum random number generator using photon-number path entanglement
Kwon, Osung; Cho, Young-Wook; Kim, Yoon-Ho
2010-08-01
We report an experimental implementation of quantum random number generator based on the photon-number-path entangled state. The photon-number-path entangled state is prepared by means of two-photon Hong-Ou-Mandel quantum interference at a beam splitter. The randomness in our scheme is of truly quantum mechanical origin as it comes from the projection measurement of the entangled two-photon state. The generated bit sequences satisfy the standard randomness test.

If g fixes elements of Q(√d), where d is a square-free positive number, on the circuit of the coset diagram, then d ＝ 2 and there are only four pairs of ambiguous numbers on the circuit.

Bernoulli numbers and zeta functions
Arakawa, Tsuneo; Kaneko, Masanobu
2014-01-01
Two major subjects are treated in this book. The main one is the theory of Bernoulli numbers and the other is the theory of zeta functions. Historically, Bernoulli numbers were introduced to give formulas for the sums of powers of consecutive integers. The real reason that they are indispensable for number theory, however, lies in the fact that special values of the Riemann zeta function can be written by using Bernoulli numbers. This leads to more advanced topics, a number of which are treated in this book: Historical remarks on Bernoulli numbers and the formula for the sum of powers of consecutive integers; a formula for Bernoulli numbers by Stirling numbers; the Clausen–von Staudt theorem on the denominators of Bernoulli numbers; Kummer's congruence between Bernoulli numbers and a related theory of p-adic measures; the Euler–Maclaurin summation formula; the functional equation of the Riemann zeta function and the Dirichlet L functions, and their special values at suitable integers; various formulas of ...

This report is an updated version of the 2014 Compendium of Experimental Cetane Number Data and presents a compilation of measured cetane numbers for pure chemical compounds. It includes all available single-compound cetane number data found in the scientific literature up until December 2016 as well as a number of previously unpublished values, most measured over the past decade at the National Renewable Energy Laboratory. This version of the compendium contains cetane values for 496 pure compounds, including 204 hydrocarbons and 292 oxygenates. 176 individual measurements are new to this version of the compendium, all of them collected using ASTM Method D6890, which utilizes an Ignition Quality Tester (IQT) a type of constant-volume combustion chamber. For many compounds, numerous measurements are included, often collected by different researchers using different methods. The text of this document is unchanged from the 2014 version, except for the numbers of compounds in Section 3.1, the Appendices, Table 1. Primary Cetane Number Data Sources and Table 2. Number of Measurements Included in Compendium. Cetane number is a relative ranking of a fuel's autoignition characteristics for use in compression ignition engines. It is based on the amount of time between fuel injection and ignition, also known as ignition delay. The cetane number is typically measured either in a single-cylinder engine or a constant-volume combustion chamber. Values in the previous compendium derived from octane numbers have been removed and replaced with a brief analysis of the correlation between cetane numbers and octane numbers. The discussion on the accuracy and precision of the most commonly used methods for measuring cetane number has been expanded, and the data have been annotated extensively to provide additional information that will help the reader judge the relative reliability of individual results.

Humans and non-human primates share an elemental quantification system that resides in a dedicated neural network in the parietal and frontal lobes. In this cortical network, 'number neurons' encode the number of elements in a set, its cardinality or numerosity, irrespective of stimulus appearance across sensory motor systems, and from both spatial and temporal presentation arrays. After numbers have been extracted from sensory input, they need to be processed to support goal-directed behaviour. Studying number neurons provides insights into how information is maintained in working memory and transformed in tasks that require rule-based decisions. Beyond an understanding of how cardinal numbers are encoded, number processing provides a window into the neuronal mechanisms of high-level brain functions.
Number Comparison and Number Line Estimation Rely on Different Mechanisms
Directory of Open Access Journals (Sweden)
Delphine Sasanguie
2013-12-01
Full Text Available The performance in comparison and number line estimation is assumed to rely on the same underlying representation, similar to a compressed mental number line that becomes more linear with age. We tested this assumption explicitly by examining the relation between the linear/logarithmic fit in a non-symbolic number line estimation task and the size effect (SE in a non-symbolic comparison task in first-, second-, and third graders. In two experiments, a correlation between the estimation pattern in number line estimation and the SE in comparison was absent. An ANOVA showed no difference between the groups of children with a linear or a logarithmic representation considering their SE in comparison. This suggests that different mechanisms underlie both basic number processing tasks.

In this work we show that the prime distribution is deterministic. Indeed the set of prime numbers P can be expressed in terms of two subsets of N using three specific selection rules, acting on two sets of prime candidates. The prime candidates are obtained in terms of the first perfect number. The asymptotic behaviour is also considered. We obtain for the first time an explicit relation for generating the full set P of prime numbers smaller than n or equal to n.

Our analysis considers only regular papers as we do not include short papers, demo papers, posters, tutorials or panels into our statistics. We rank the research scholars according to their number of publication in each conference/journal separately and in combined. We also report about the growth in the number of research publications and the size of the research community in the last decade.
Brain representations of negative numbers.
Parnes, Michael; Berger, Andrea; Tzelgov, Joseph
2012-12-01
Participants performed a physical comparison task of pairs of positive and pairs of negative one-digit numbers while their electrophysiological brain activity was measured. The numerical value of the presented digits was either congruent or incongruent with the physical size of the digits. Analysis has shown that the earliest event-related potential (ERP) difference between positive and negative numbers was found in the P300 ERP component peak, where there was an inverse effect of congruity in the negative pairs, compared with the positive ones. This pattern of results supports the idea that natural numbers serve as primitives of the human cognitive system, whereas negative numbers are apparently generated if needed.

Theory of the L-mode confinement in toroidal plasmas is developed. The Prandtl number, the ratio between the ion viscosity and the thermal conductivity is obtained for the anomalous transport process which is caused by the self-sustained turbulence in the toroidal plasma. It is found that the Prandtl number is of order unity both for the ballooning mode turbulence in tokamaks and for the interchange mode turbulence in helical system. The influence on the anomalous transport and fluctuation level is evaluated. Hartmann number and magnetic Prandtl number are also discussed. (author).

In this paper, we consider a two-parameter polynomial generalization, denoted by ${\\mathcal G}_{a,b}(n, k; r)$, of the $r$-Lah numbers which reduces to these recently introduced numbers when $a = b = 1$. We present several identities for ${\\mathcal G}_{a,b}(n, k; r)$ that generalize earlier identities given for the $r$-Lah and $r$-Stirling numbers. We also provide combinatorial proofs of some earlier identities involving the $r$-Lah numbers by defining appropriate sign-changing involutions. Generalizing these arguments yields orthogonality-type relations that are satisfied by ${\\mathcal G}_{a,b}(n, k; r)$.

Public health, public trust and lobbying.
Wynia, Matthew K
2007-06-01
Each year, infection with Human Papillomavirus (HPV) leads to millions of abnormal Pap smears and thousands of cases of cervical cancer in the US. Throughout the developing world, where Pap smears are less common, HPV is a leading cause of cancer death among women. So when the international pharmaceutical giant Merck developed a vaccine that could prevent infection with several key strains of HPV, the public health community was anxious to celebrate a major advance. But then marketing and lobbying got in the way. Merck chose to pursue an aggressive lobbying campaign, trying to make its new vaccine mandatory for young girls. The campaign stoked public mistrust about how vaccines come to be mandated, and now it's not just Merck's public image that has taken a hit. The public health community has also been affected. What is the lesson to be learned from this story? Public health communication relies on public trust.

This article explores public relations effectiveness in public health institutions. First, the two major elements that comprise public relations effectiveness are discussed: reputation management and stakeholder relations. The factors that define effective reputation management are examined, as are the roles of issues and crisis management in building and maintaining reputation. The article also examines the major facets of stakeholder relations, including an inventory of stakeholder linkages and key audiences, such as the media. Finally, methods of evaluating public relations effectiveness at both the program level and the institutional level are explored.

Depreciation of public goods in spatial public goods games
Shi, Dong-Mei; Zhuang, Yong; Li, Yu-Jian; Wang, Bing-Hong
2011-10-01
In real situations, the value of public goods will be reduced or even lost because of external factors or for intrinsic reasons. In this work, we investigate the evolution of cooperation by considering the effect of depreciation of public goods in spatial public goods games on a square lattice. It is assumed that each individual gains full advantage if the number of the cooperators nc within a group centered on that individual equals or exceeds the critical mass (CM). Otherwise, there is depreciation of the public goods, which is realized by rescaling the multiplication factor r to (nc/CM)r. It is shown that the emergence of cooperation is remarkably promoted for CM > 1 even at small values of r, and a global cooperative level is achieved at an intermediate value of CM = 4 at a small r. We further study the effect of depreciation of public goods on different topologies of a regular lattice, and find that the system always reaches global cooperation at a moderate value of CM = G - 1 regardless of whether or not there exist overlapping triangle structures on the regular lattice, where G is the group size of the associated regular lattice.

We present the relation between the genus in cosmology and the Betti numbers for excursion sets of three- and two-dimensional smooth Gaussian random fields, and numerically investigate the Betti numbers as a function of threshold level. Betti numbers are topological invariants of figures that can be used to distinguish topological spaces. In the case of the excursion sets of a three-dimensional field there are three possibly non-zero Betti numbers; $\\beta_0$ is the number of connected regions, $\\beta_1$ is the number of circular holes, and $\\beta_2$ is the number of three-dimensional voids. Their sum with alternating signs is the genus of the surface of excursion regions. It is found that each Betti number has a dominant contribution to the genus in a specific threshold range. $\\beta_0$ dominates the high-threshold part of the genus curve measuring the abundance of high density regions (clusters). $\\beta_1$ dominates the genus near the median thresholds which measures the topology of negatively curved iso-den...

The natural numbers may be our simplest, most useful, and best-studied abstract concepts, but their origins are debated. I consider this debate in the context of the proposal, by Gallistel and Gelman, that natural number system is a product of cognitive evolution and the proposal, by Carey, that it is a product of human cultural history. I offer a…

Twitter can serve as a powerful communication modality to both "push" and "pull" public health data; each user is a potential public health sensor and actor. However, in 2012, only 8% of local health departments had Twitter accounts. We outline how Twitter works, describe how to access public tweets for public health surveillance purposes, review the literature on Twitter's current and potential role supporting public health's essential services, summarize Twitter's limitations, and make recommendations for health department use.
Generalized Bernoulli-Hurwitz numbers and the universal Bernoulli numbers
Energy Technology Data Exchange (ETDEWEB)
Onishi, Yoshihiro [Faculty of Education Human Sciences, University of Yamanashi, Takeda, Kofu (Japan)
2011-10-31
The three fundamental properties of the Bernoulli numbers, namely, the von Staudt-Clausen theorem, von Staudt's second theorem, and Kummer's original congruence, are generalized to new numbers that we call generalized Bernoulli-Hurwitz numbers. These are coefficients in the power series expansion of a higher-genus algebraic function with respect to a suitable variable. Our generalization differs strongly from previous works. Indeed, the order of the power of the modulus prime in our Kummer-type congruences is exactly the same as in the trigonometric function case (namely, Kummer's own congruence for the original Bernoulli numbers), and as in the elliptic function case (namely, H. Lang's extension for the Hurwitz numbers). However, in other past results on higher-genus algebraic functions, the modulus was at most half of its value in these classical cases. This contrast is clarified by investigating the analogue of the three properties above for the universal Bernoulli numbers. Bibliography: 34 titles.

Urban aerosol number size distributions
Directory of Open Access Journals (Sweden)
T. Hussein
2004-01-01
Full Text Available Aerosol number size distributions have been measured since 5 May 1997 in Helsinki, Finland. The presented aerosol data represents size distributions within the particle diameter size range 8-400nm during the period from May 1997 to March 2003. The daily, monthly and annual patterns of the aerosol particle number concentrations were investigated. The temporal variation of the particle number concentration showed close correlations with traffic activities. The highest total number concentrations were observed during workdays; especially on Fridays, and the lowest concentrations occurred during weekends; especially Sundays. Seasonally, the highest total number concentrations were observed during winter and spring and lower concentrations were observed during June and July. More than 80% of the number size distributions had three modes: nucleation mode (30nm, Aitken mode (20-100nm and accumulation mode (}$'>90nm. Less than 20% of the number size distributions had either two modes or consisted of more than three modes. Two different measurement sites were used; in the first (Siltavuori, 5.5.1997-5.3.2001, the arithmetic means of the particle number concentrations were 7000cm, 6500cm, and 1000cm respectively for nucleation, Aitken, and accumulation modes. In the second site (Kumpula, 6.3.2001-28.2.2003 they were 5500cm, 4000cm, and 1000cm. The total number concentration in nucleation and Aitken modes were usually significantly higher during workdays than during weekends. The temporal variations in the accumulation mode were less pronounced. The lower concentrations at Kumpula were mainly due to building construction and also the slight overall decreasing trend during these years. During the site changing a period of simultaneous measurements over two weeks were performed showing nice correlation at both sites.
Graspable objects shape number processing

2011-12-01
Full Text Available The field of numerical cognition represents an interesting case for action-based theories of cognition, since number is a special kind of abstract concept. Several studies have shown that within the parietal lobes adjacent neural regions code numerical magnitude and grasping-related information. This anatomical proximity between brain areas involved in number and sensorimotor processes may account for interactions between numerical magnitude and action. In particular, recent studies has demonstrated a causal role of action perception on numerical magnitude processing. If objects are represented in terms of actions (affordances, the causal role of action on number processing should extend to the case of objects affordances. This study investigates the relationship between numbers and objects affordances in two experiments, without (Experiment 1 or with (Experiment 2 a motor action execution (i.e., participants were asked to hold an object in their hands during the task. The task consisted in repeating aloud the odd or even digit within a pair depending on the type of the preceding or following object. Order of presentation (object-number vs. number-object, object type (graspable vs. ungraspable, object size (small vs. large, and Numerical magnitude (small vs. large were manipulated for each experiment. Experiment 1 showed a facilitation – in terms of quicker responses - for graspable over ungraspable objects preceded by numbers, and an effect of numerical magnitude after the presentation of graspable objects. Experiment 2 demonstrated that the action execution enhanced overall the sensitivity to numerical magnitude, however interfering with the effects of objects affordances on number processing. Overall, these findings demonstrate that numbers and graspable objects communicate with each other, supporting the view that abstract concepts may be grounded in motor experience.
From networked publics to issue publics

Birkbak, Andreas
2013-01-01
As an increasing part of everyday life becomes connected with the web in many areas of the globe, the question of how the web mediates political processes becomes still more urgent. Several scholars have started to address this question by thinking about the web in terms of a public space...... that the complex connectivity of the web puts user privacy at risk and enables the enclosure of public debate in virtual echo chambers. Our first argument is that these concerns are united by a set assumptions coming from liberal political philosophy that are rarely made explicit. As a second contribution......, this paper points towards an alternative way to think about publics by proposing a pragmatist reorientation of the public/private distinction in web science, away from seeing two spheres that needs to be kept separate, towards seeing the public and the private as something that is continuously connected...
Numbered nasal discs for waterfowl
Bartonek, J.C.; Dane, C.W.
1964-01-01
Numbered nasal discs were successfully used in studies requiring large numbers of individually marked waterfowl. The procedure for constructing these discs is outlined. Blue-winged teal (Anas discors) with 5/8-inch discs, and canvasback (Aythya valisineria) and redhead (A. americana) with 3/4-inch discs can be individually identified up to 50 and 80 yards, respectively, with a gunstock-mounted, 20-power spotting scope. The particular value of these markers is their durability, the number of combinations possible, and the apparent absence of behavioral or mortality influence among such species as the blue-winged teal.

A String-Based Public Key Cryptosystem
Andrecut, M
2014-01-01
Traditional public key cryptography is based on number theory, and suffers from problems such as dealing with very large numbers and large prime numbers, making key creation cumbersome. Here, we propose a new public key cryptosystem based on strings only, which avoids the difficulties of the traditional number theory approach. The security mechanism for generating public and secret keys is ensured by a recursive encoding mechanism embedded in a quasi-commutative-random function, resulted from the composition of a quasi-commutative function with a pseudo-random function. Due to the inherent construction algorithm of the the proposed cryptosystem, the resulted mathematical inversion problem is likely to be harder than the classical discrete logarithm or integer factorization problems. Furthermore, the proposed cryptosystem is immune against the known quantum algorithm attacks.

Spectral numbers in Floer theories
Usher, Michael
2007-01-01
The chain complexes underlying Floer homology theories typically carry a real-valued filtration, allowing one to associate to each Floer homology class a spectral number defined as the infimum of the filtration levels of chains representing that class. These spectral numbers have been studied extensively in the case of Hamiltonian Floer homology by Oh, Schwarz, and others. We prove that the spectral number associated to any nonzero Floer homology class is always finite, and that the infimum in the definition of the spectral number is always attained. In the Hamiltonian case, this implies that what is known as the "nondegenerate spectrality" axiom holds on all closed symplectic manifolds. Our proofs are entirely algebraic and rather elementary, and apply to any Floer-type theory (including Novikov homology) satisfying certain standard formal properties provided that one works with coefficients in a Novikov ring whose degree-zero part \\Lambda_0 is a field. The key ingredient is a theorem about linear transforma...

Euclid's Number-Theoretical Work
Zhang, Shaohua
2009-01-01
The object of this paper is to affirm the number-theoretical role of Euclid and the historical significance of Euclid's algorithm. We give a brief introduction about Euclid's number-theoretical work. Our study is the first to show that Euclid's algorithm is essentially equivalent with Division algorithm which is the basis of Theory of Divisibility. Note also that Euclid's algorithm implies Euclid's first theorem and Euclid's second theorem. Thus, in the nature of things, Euclid's algorithm is the most important number-theoretical work of Euclid. For this reason, we further summarize briefly the influence of Euclid's algorithm. It leads to the conclusion that Euclid's algorithm is the greatest number-theoretical achievement of the age.

International audience; The Bruhat order gives a poset structure to any Coxeter group. The ideal of elements in this poset having boolean principal order ideals forms a simplicial poset. This simplicial poset defines the boolean complex for the group. In a Coxeter system of rank n, we show that the boolean complex is homotopy equivalent to a wedge of (n-1)-dimensional spheres. The number of these spheres is the boolean number, which can be computed inductively from the unlabeled Coxeter syste...

Full Text Available Aerosol number size distributions were measured continuously in Helsinki, Finland from 5 May 1997 to 28 February 2003. The daily, monthly and annual patterns were investigated. The temporal variation of the particle number concentration was seen to follow the traffic density. The highest total particle number concentrations were usually observed during workdays; especially on Fridays, and the lower concentrations occurred during weekends; especially Sundays. Seasonally, the highest total number concentrations were usually observed during winter and spring and the lowest during June and July. More than 80\\% of the particle number size distributions were tri-modal: nucleation mode (Dp < 30 nm, Aitken mode (20–100 nm and accumulation mode (Dp > 90 nm. Less than 20% of the particle number size distributions have either two modes or consisted of more than three modes. Two different measurement sites are used; in the first place (Siltavuori, 5 May 1997–5 March 2001, the overall means of the integrated particle number concentrations were 7100 cm^{−3}, 6320 cm^{−3}, and 960 cm^{−3}, respectively, for nucleation, Aitken, and accumulation modes. In the second site (Kumpula, 6 March 2001–28 February 2003 they were 5670 cm^{−3}, 4050 cm^{−3}, and 900 cm^{−3}. The total number concentration in nucleation and Aitken modes were usually significantly higher during weekdays than during weekends. The variations in accumulation mode were less pronounced. The smaller concentrations in Kumpula were mainly due to building construction and also slight overall decreasing trend during these years. During the site changing a period of simultaneous measurements over two weeks were performed showing nice correlation in both sites.

We introduce a new metric on a space of right-sided infinite sequences drawn from a finite alphabet. Emerging from a problem of entropy estimation of a discrete stationary ergodic process, the metric is important on its own part and exhibits some interesting properties. Notably, the number of distinct metric values for a set of sequences of length m is equal to Fm+3 - 1, where Fm is a Fibonacci number.

Dimensionless numbers in additive manufacturing
Mukherjee, T.; Manvatkar, V.; De, A.; DebRoy, T.
2017-02-01
The effects of many process variables and alloy properties on the structure and properties of additively manufactured parts are examined using four dimensionless numbers. The structure and properties of components made from 316 Stainless steel, Ti-6Al-4V, and Inconel 718 powders for various dimensionless heat inputs, Peclet numbers, Marangoni numbers, and Fourier numbers are studied. Temperature fields, cooling rates, solidification parameters, lack of fusion defects, and thermal strains are examined using a well-tested three-dimensional transient heat transfer and fluid flow model. The results show that lack of fusion defects in the fabricated parts can be minimized by strengthening interlayer bonding using high values of dimensionless heat input. The formation of harmful intermetallics such as laves phases in Inconel 718 can be suppressed using low heat input that results in a small molten pool, a steep temperature gradient, and a fast cooling rate. Improved interlayer bonding can be achieved at high Marangoni numbers, which results in vigorous circulation of liquid metal, larger pool dimensions, and greater depth of penetration. A high Fourier number ensures rapid cooling, low thermal distortion, and a high ratio of temperature gradient to the solidification growth rate with a greater tendency of plane front solidification.
Grammatical typology and frequency analysis: number availability and number use
Directory of Open Access Journals (Sweden)
Dunstan Brown
2013-12-01
Full Text Available The Smith-Stark hierarchy, a version of the Animacy Hierarchy, offers a typology of the cross-linguistic availability of number. The hierarchy predicts that the availability of number is not arbitrary. For any language, if the expression of plural is available to a noun, it is available to any noun of a semantic category further to the left of the hierarchy. In this article we move one step further by showing that the structure of the hierarchy can be observed in a statistical model of number use in Russian. We also investigate three co-variates: plural preference, pluralia tantum and irregularity effects; these account for an item's behaviour being different than that solely expected from its animacy position.
Number matters: control of mammalian mitochondrial DNA copy number.
Clay Montier, Laura L; Deng, Janice J; Bai, Yidong
2009-03-01
Regulation of mitochondrial biogenesis is essential for proper cellular functioning. Mitochondrial DNA (mtDNA) depletion and the resulting mitochondrial malfunction have been implicated in cancer, neurodegeneration, diabetes, aging, and many other human diseases. Although it is known that the dynamics of the mammalian mitochondrial genome are not linked with that of the nuclear genome, very little is known about the mechanism of mtDNA propagation. Nevertheless, our understanding of the mode of mtDNA replication has advanced in recent years, though not without some controversies. This review summarizes our current knowledge of mtDNA copy number control in mammalian cells, while focusing on both mtDNA replication and turnover. Although mtDNA copy number is seemingly in excess, we reason that mtDNA copy number control is an important aspect of mitochondrial genetics and biogenesis and is essential for normal cellular function.
