Positioning Shakespeare at the "crossroads of manuscript and print" and exploring what the choice of print or manuscript reveals about the poet's intended audience and the social persona the poet wanted to assume and fashion, argues that "Shakespeare's authorial self-presentation begins as a poet and, more specifically, as a print-published poet" with the publication of Venus and Adonis in 1593 and the allusion to the publication of Rape of Lucrece in the next year. Yet also considers the imp...

Our purpose was to determine if associations exist between titles characteristics and citation numbers in Radiology, American Journal of Roentgenology (AJR), and American Journal of Neuroradiology (AJNR). This retrospective study is Institutional Review Board exempt. We searched Web of Science for all original research and review articles in Radiology, AJR, and AJNR between 2006 and 2012 and tabulated number of words in the title, presence of a colon symbol, and presence of an acronym. We used a Poisson regression model to evaluate the association between number of citations and title characteristics. We then used the Wald test to detect pairwise differences in the effect of title characteristics on number of citations among the 3 journals. Between 2006 and 2012, Radiology published 2662, AJR 3998, and AJNR 2581 original research and review articles. There was a citation number increase per title word increase of 1.6% for AJNR and 2.6% for AJR and decrease of 0.8% for Radiology. For all, P citation increases for AJNR (16%), Radiology (14%), and AJR (7.4%). Title acronym was associated with citation increases for AJNR (10%), Radiology (14%), and AJR (13.3%).

Reviewing Manuscripts for Biomedical Journals
Garmel, Gus M
2010-01-01
Writing for publication is a complex task. For many professionals, producing a well-executed manuscript conveying one's research, ideas, or educational wisdom is challenging. Authors have varying emotions related to the process of writing for scientific publication. Although not studied, a relationship between an author's enjoyment of the writing process and the product's outcome is highly likely. As with any skill, practice generally results in improvements. Literature focused on preparing manuscripts for publication and the art of reviewing submissions exists. Most journals guard their reviewers' anonymity with respect to the manuscript review process. This is meant to protect them from direct or indirect author demands, which may occur during the review process or in the future. It is generally accepted that author identities are masked in the peer-review process. However, the concept of anonymity for reviewers has been debated recently; many editors consider it problematic that reviewers are not held accountable to the public for their decisions. The review process is often arduous and underappreciated, one reason why biomedical journals acknowledge editors and frequently recognize reviewers who donate their time and expertise in the name of science. This article describes essential elements of a submitted manuscript, with the hopes of improving scientific writing. It also discusses the review process within the biomedical literature, the importance of reviewers to the scientific process, responsibilities of reviewers, and qualities of a good review and reviewer. In addition, it includes useful insights to individuals who read and interpret the medical literature. PMID:20740129

2015-01-01
Purpose: To evaluate characteristics associated with higher rates of acceptance for original manuscripts submitted for publication to the International Journal of Radiation Oncology • Biology • Physics (IJROBP) and describe the fate of rejected manuscripts. Methods and Materials: Manuscripts submitted to the IJROBP from May 1, 2010, to August 31, 2010, and May 1, 2012, to August 31, 2012, were evaluated for author demographics and acceptance status. A PubMed search was performed for each IJROBP-rejected manuscript to ascertain whether the manuscript was ultimately published elsewhere. The Impact Factor of the accepting journal and the number of citations of the published manuscript were also collected. Results: Of the 500 included manuscripts, 172 (34.4%) were accepted and 328 (65.6%) were rejected. There was no significant difference in acceptance rates according to gender or degree of the submitting author, but there were significant differences seen based on the submitting author's country, rank, and h-index. On multivariate analysis, earlier year submitted (P<.0001) and higher author h-index (P=.006) remained significantly associated with acceptance into the IJROBP. Two hundred thirty-five IJROBP-rejected manuscripts (71.7%) were ultimately published in a PubMed-listed journal as of July 2014. There were no significant differences in any submitting author characteristics. Journals accepting IJROBP-rejected manuscripts had a lower median [interquartile range] 2013 impact factor compared with the IJROBP (2.45 [1.53-3.71] vs 4.176). The IJROBP-rejected manuscripts ultimately published elsewhere had a lower median [interquartile range] number of citations (1 [0-4] vs 6 [2-11]; P<.001), which persisted on multivariate analysis. Conclusions: The acceptance rate for manuscripts submitted to the IJROBP is approximately one-third, and approximately 70% of rejected manuscripts are ultimately published in other PubMed-listed journals, but these ultimate

Astronomical knowledge transmission through illustrated Aratea manuscripts
Dolan, Marion
2017-01-01
This carefully researched monograph is a historical investigation of the illustrated Aratea astronomical manuscript and its many interpretations over the centuries. Aratus' 270 B.C.E. Greek poem describing the constellations and astrological phenomena was translated and copied over 800 years into illuminated manuscripts that preserved and illustrated these ancient stories about the constellations. The Aratea survives in its entirety due to multiple translations from Greek to Latin and even to Arabic, with many illuminated versions being commissioned over the ages. The survey encompasses four interrelated disciplines: history of literature, history of myth, history of science, and history of art. Aratea manuscripts by their nature are a meeting place of these distinct branches, and the culling of information from historical literature and from the manuscripts themselves focuses on a wider, holistic view; a narrow approach could not provide a proper prospective. What is most essential to know about this work is...

2018-01-01
Full Text Available Jawi writing is the main form of writing in various manuscripts recovered around the Archipelago, especially during the early arrival of Islam. These manuscripts are found to record history, art, culture, language, social, as well as ancient knowledge. The usage of Jawi writings had covered a number of calligraphy which are high in value with deep philosophical meaning, are full with creative notion as well as countless of patterns that went along with the call to Islam around the Archipelago in a relatively short period of time. The development of Jawi writing had been immortalized in various genres such as books, manuscripts and letters written by individual writers and in groups as a local way of living. This writing was also introduced through a long process using certain methods of writing and reading, and kept as individual as well as institutional collections all around the Archipelago. This article is focused in various manuscripts that not only were exclusively used as learning and teaching aids, but were also garnished as beautiful symbols and philosophical Islamic art that deserves a high degree of honour. This article’s objective is to deeply analyze the usage of this writing from manuscripts found around the Archipelago as a proof on the importance of this form of writing. The methodology of this article is library study, through a number of theories and methods. The implication of this article is hoped to form a certain standard as well as its own identity for the local society through their acceptance of this writing form, especially during the early arrival of Islam in the Archipelago thus deemed as a national treasure.

Although physicians’ communication style and perceptions affect outcomes, few studies have examined how these perceptions relate to the way physicians communicate with patients. Moreover, while any number of factors may affect the communication process, few studies have analyzed these effects collectively in order to identify the most powerful influences on physician communication and perceptions. Adopting an ecological approach, this investigation examined: (a) the relationships of physicians’ patient-centered communication (informative, supportive, partnership-building) and affect (positive, contentious) on their perceptions of the patient, and (b) the degree to which communication and perceptions were affected by the physicians’ characteristics, patients’ demographic characteristics, physician-patient concordance, and the patient’s communication. Physicians (N = 29) and patients (N = 207) from 10 outpatient settings in the United States participated in the study. From audio-recordings of these visits, coders rated the physicians’ communication and affect as well as the patients’ participation and affect. Doctors were more patient-centered with patients they perceived as better communicators, more satisfied, and more likely to adhere. Physicians displayed more patient-centered communication and more favorably perceived patients who expressed positive affect, were more involved, and who were less contentious. Physicians were more contentious with black patients, whom they also perceived as less effective communicators and less satisfied. Finally, physicians who reported a patient-centered orientation to the doctor-patient relationship also were more patient-centered in their communication. The results suggest that reciprocity and mutual influence have a strong effect on these interactions in that more positive (or negative) communication from one participant leads to similar responses from the other. Physicians’ encounters with black patients
Manuscript Transcription by Crowdsourcing: Transcribe Bentham

Martin Moyle
2011-02-01
Full Text Available Transcribe Bentham is testing the feasibility of outsourcing the work of manuscript transcription to members of the public. UCL Library Services holds 60,000 folios of manuscripts of the philosopher and jurist Jeremy Bentham (1748–1832. Transcribe Bentham will digitise 12,500 Bentham folios, and, through a wiki-based interface, allow volunteer transcribers to take temporary ownership of manuscript images and to create TEI-encoded transcription text for final approval by UCL experts. Approved transcripts will be stored and preserved, with the manuscript images, in UCL’s public Digital Collections repository. The project makes innovative use of traditional library material. It will stimulate public engagement with UCL’s scholarly archive collections and the challenges of palaeography and manuscript transcription; it will raise the profile of the work and thought of Jeremy Bentham; and it will create new digital resources for future use by professional researchers. Towards the end of the project, the transcription tool will be made available to other projects and services. This paper is based on a presentation given by the lead author at LIBER’s 39th Annual General Conference in Aarhus, Denmark, 2010.
Hindrance of conservation biology by delays in the submission of manuscripts.
O'Donnell, Ryan P; Supp, Sarah R; Cobbold, Stephanie M
2010-04-01
Timely dissemination of scientific findings depends not only on rapid publication of submitted manuscripts, a topic which has received much discussion, but also on rapid submission of research after the research is completed. We measured submission delay (time from the last date of data collection to the submission of a manuscript) for every paper from 14 journals in 2007 and compared these submission delays among four fields of biology (conservation, taxonomy, behavior, and evolution). Manuscripts published in leading journals in the field of conservation biology have the longest delays in publication of accepted manuscripts and the longest intervals between completion of research and submission of the manuscript. Delay in manuscript submission accounts for more than half of the total time from last date of data collection to publication. Across fields, the number of authors was significantly negatively correlated with submission delay, but conservation journals had the second highest number of authors and the greatest submission delay, so submission of conservation manuscripts was not hindered by a shortage of collaboration relative to other fields. Rejection rates were greater in conservation journals than in behavior and evolution, but rejection times were faster; thus, there were no obvious net differences among fields in the time papers spent waiting to be rejected. Publication delay has been reduced significantly in the last 7 years, but was still greater in conservation journals than in any of the other three fields we studied. Thus, the urgent field of conservation biology is hindered in both preparation and publication of manuscripts.
The manuscript of Kartoteka (Card Index
Directory of Open Access Journals (Sweden)
Zbigniew Władysław Solski
2009-01-01
Full Text Available At the beginning of the 70s Tadeusz Różewicz presented the manuscript of Card Index to Professor Józef Kelera. It might have stayed a secret of friendship of the dramatist and the critic, however, Różewicz revealed the initials of his friend when in a commenatry to the play, he posed a question, whether there was a full stop after the last word in the manuscript or not? Posing this question, the author claimed the integrality of his masterpiece which was threatened by the widespread interpretations of Card Index as a play of a loose and dispersed structure. Appreciating the value of this question, I turned to Professor Kelera. This way I have had an access to the autograph of the play. In this manuscript has been preserved the play from before its final editing, which its author must surely have made during typing the text. Handwritten notes contain two unknown versions of the play with fragments which would not have been passed by the censors in the then Polish People’s Republic. In the reading of the manuscript the functions of the word and its graphic shape appeared of equal importance, so this version of Card Index can be recognised as a masterpiece of literature.
Multiscale Pigment Analysis of Medieval Illuminated Manuscripts
Sestak, Erica; Manukyan, Khachatur; Wiescher, Michael; Gura, David
2017-09-01
Three medieval illuminated manuscripts (codd. Lat. b. 1; Lat. b. 2; Lat. e. 4), housed at the University of Notre Dame's Hesburgh Library, vary in style, pigments, scribes, and regions, despite all three being Psalters used in the Late Middle Ages. XRF and Raman spectroscopy, which provided the elemental and molecular composition of the pigments, respectively, were used to analyze the pigments' compositions in an attempt to narrow further the manuscripts' possible origins. This experimental investigation emphasizes the importance of understanding the history of the manuscript through their pigments. Codd. Lat. b. 1 and Lat. b. 2 are Latinate German Psalters from the fifteenth century likely used in Katharinenkloster in Nuremberg. While there are visible differences in style within each Psalter, the variations in some of the pigment compositions, such as the inconstant presence of zinc, suggest different admixtures. Cod. Lat. e. 4 is a Latinate English Psalter from the fourteenth century, and it was written by two scribes and illuminated by two distinct painters. It is currently being tested to determine whether there are any correlations between the scribes and painters. These physical analyses will clarify the origins and provenances of the manuscripts.

Quantifying the effect of editor-author relations on manuscript handling times.
Sarigöl, Emre; Garcia, David; Scholtes, Ingo; Schweitzer, Frank
2017-01-01
In this article we study to what extent the academic peer review process is influenced by social relations between the authors of a manuscript and the editor handling the manuscript. Taking the open access journal PlosOne as a case study, our analysis is based on a data set of more than 100,000 articles published between 2007 and 2015. Using available data on handling editor, submission and acceptance time of manuscripts, we study the question whether co-authorship relations between authors and the handling editor affect the manuscript handling time , i.e. the time taken between the submission and acceptance of a manuscript. Our analysis reveals (1) that editors handle papers co-authored by previous collaborators significantly more often than expected at random, and (2) that such prior co-author relations are significantly related to faster manuscript handling. Addressing the question whether these shorter manuscript handling times can be explained by the quality of publications, we study the number of citations and downloads which accepted papers eventually accumulate. Moreover, we consider the influence of additional (social) factors, such as the editor's experience, the topical similarity between authors and editors, as well as reciprocal citation relations between authors and editors. Our findings show that, even when correcting for other factors like time, experience, and performance, prior co-authorship relations have a large and significant influence on manuscript handling times, speeding up the editorial decision on average by 19 days.
Improving the efficiency of manuscript selection
Directory of Open Access Journals (Sweden)
A. Martínez–Abrain
2009-01-01
Full Text Available Science relies strongly on the publication of articles in scientific journals and it is clear that decisions concer¬ning which papers merit publishing should be based on a process of manuscript selection that is as objective, repeatable, reliable and transparent as possible. Manuscript selection, however, has many practical downfalls. There is considerable controversy concerning issues such as whether or not the process should be blind both for authors and reviewers in order to prevent biased selection in relation to country of origin (Budden et al., 2008, sex (Young et al. 2008 or research topic (Michaels, 2008. Another critical point is the imbalance between supply and demand of manuscripts as this likely leads to biased selection (Young et al., 2008. Also important is the issue that following rejection, the editor and reviewers of the new journal selected for would-be publication by the authors start the process from scratch, as if the opus had not already passed through a thorough process of peer review. Such rules of play seem to promote the role of sheer luck in the process of manuscript selection. Authors of a rejected paper have the growing hope of "greater luck" the next time regarding reviewer assignment as they believe in the quality of their work. For the correct advancement of science I consider there should be a common global database available to editors, where each manuscript which has been subjected to an SCI journal is recorded. It should include a copy of the editor’s and reviewers’ comments, and also the authors’ replies. Hochberg et al. (2009 recently expressed their concern regarding the fact that authors usually think that manuscript submittal is a stochastic process, whereas in fact reviewers usually focus on the same set of criticisms. To solve this problem they suggest a having colleagues reviewing a manuscript before submission, and b requiring authors to state in a cover letter that reviewer comments from the

The manuscripts and correspondence of Leibniz possess a special interest: they are invaluable as aids to the study of their author's part in the invention and development of the infinitesimal calculus. In addition, the main ideas behind Leibniz's philosophical theories lay here, in his mathematical work.This volume consists of two sections. The first part features Leibniz's own accounts of his work, and the second section comprises critical and historical notes and essays. An informative Introduction leads to the ""postscript"" to Leibniz's 1703 letter to James Bernoulli, his ""Historia et Ori

Full Text Available Hand-written or printed manuscript data are an important source for paleo-climatological studies, but bringing them into a suitable format can be a time consuming adventure with uncertain success. Before digitising such data (e.g., in the context a specific research project, it is worthwhile spending a few thoughts on the characteristics of the data, the scientific requirements with respect to quality and coverage, the metadata, and technical aspects such as reproduction techniques, digitising techniques, and quality control strategies. Here we briefly discuss the most important considerations according to our own experience and describe different methods for digitising numeric or text data (optical character recognition, speech recognition, and key entry. We present a tentative guide that is intended to help others compiling the necessary information and making the right decisions.

Full Text Available In this paper I will describe the adventurous history of an important late medieval German fechtbuch—a fighting manual—that belongs to a number of manuscripts known as the Gladiatoria group. In the beginning, the extent and the characteristics of this group of codices are explained; later on I will deal with one specific specimen that formerly belonged to a library in Germany—the Herzogliche Bibliothek in Gotha—from where it vanished during or after World War II. Until quite recently this manuscript was believed to be lost. I was able to identify a Gladiatoria manuscript from the Yale Center for British Art in New Haven, Connecticut, as that missing manuscript. The article presents a detailed description of the manuscript; it follows the path of the many places the codex passed through from the days of its creation until the present time; it offers a thorough line of argument that proves on one hand that the manuscript from New Haven is in fact identical to the one that disappeared from Gotha, and that verifies on the other hand an assumption by the renowned researcher Hans-Peter Hils that it is identical to yet another believed-to-be-lost manuscript that was sold by auction in Heidelberg in the 1950s and 1960s as single leaves; and finally it makes an attempt to reconstruct the original structure of the manuscript after it had been pulled apart.

Recognition for old Arabic manuscripts using spatial gray level dependence (SGLD

2011-03-01
Full Text Available Texture analysis forms the basis of object recognition and classification in several domains, one of these domains is historical document manuscripts because the manuscripts hold our culture heritage and also large numbers of undated manuscripts exist. This paper presents results for historical document classification of old Arabic manuscripts using texture analysis and a segmentation free approach. The main objective is to discriminate between historical documents of different writing styles to three different ages: Contemporary (Modern Age, Ottoman Age and Mamluk Age. This classification depends on a Spatial Gray-level Dependence (SGLD technique which provides eight distinct texture features for each sample document. We applied Stepwise Discriminant Analysis and Multiple discriminant analysis methods to decrease the dimensionality of features and extract training vector features from samples. To classify historical documents into three main historical age classes the decision tree classification is applied. The system has been tested on 48 Arabic historical manuscripts documents from the Dar Al-Kotob Al-Masria Library. Our results so far yield 95.83% correct classification for the historical Arabic documents.

Peer-reviewed publication plays important roles in disseminating research findings, developing generalisable knowledge and garnering recognition for authors and institutions. Nonetheless, many bemoan the whole manuscript writing process, intimidated by the arbitrary and somewhat opaque conventions. This paper offers practical advice about organising and writing a manuscript reporting quality improvement or patient safety research for submission to a peer-reviewed journal. Each section of the paper discusses a specific manuscript component-from title, abstract and each section of the manuscript body, through to reference list and tables and figures-explaining key principles, offering content organisation tips and providing an example of how this section may read. The paper also offers a checklist of common mistakes to avoid in a manuscript.

Full Text Available Style and format are important criteria for evaluating a journal and indexing it in major databases. In Korean science, technology, and medical journals, interest in manuscript editing has increased over the past seven to eight years, and the responsibilities of manuscript editors have expanded as well. However, since no clear standards for the roles and qualifications for manuscript editors are yet available, a formal certification system is needed to establish appropriate standards and to provide professional training. To identify ways of developing a manuscript editor certification program in Korea, this study investigated similar certification programs in and outside the country and surveyed 195 Korean editors, manuscript editors, publishers, and medical librarians. The survey revealed that manuscript editors were necessary (mean score of 4.38 on a five-point Likert scale, with a score of 5 indicating strong agreement, and that their main contributions were efficiently managing the editorial board, improving the accuracy of references, and accelerating the editing process. The respondents were also positive about the possibility of implementing a manuscript editor certification; 45.1% showed interest in becoming certified, and 47.1% reported interest in hiring a certified manuscript editor. Regarding the system for issuing certification, respondents favored a professional training course (53.1%, validation of work experience (27.1%, or an examination (16.8%. This study concludes that it is essential to establish a formal certification program to train manuscript editors properly, and an examination system is the most efficient and suitable method for managing the certification process.
Writing biomedical manuscripts part I: fundamentals and general rules.
Ohwovoriole, A E
2011-01-01
It is a professional obligation for health researchers to investigate and communicate their findings to the medical community. The writing of a publishable scientific manuscript can be a daunting task for the beginner and to even some established researchers. Many manuscripts fail to get off the ground and/or are rejected. The writing task can be made easier and the quality improved by using and following simple rules and leads that apply to general scientific writing .The manuscript should follow a standard structure:(e.g. (Abstract) plus Introduction, Methods, Results, and Discussion/Conclusion, the IMRAD model. The authors must also follow well established fundamentals of good communication in science and be systematic in approach. The manuscript must move from what is currently known to what was unknown that was investigated using a hypothesis, research question or problem statement. Each section has its own style of structure and language of presentation. The beginning of writing a good manuscript is to do a good study design and to pay attention to details at every stage. Many manuscripts are rejected because of errors that can be avoided if the authors follow simple guidelines and rules. One good way to avoid potential disappointment in manuscript writing is to follow the established general rules along with those of the journal in which the paper is to be published. An important injunction is to make the writing precise, clear, parsimonious, and comprehensible to the intended audience. The purpose of this article is to arm and encourage potential biomedical authors with tools and rules that will enable them to write contemporary manuscripts, which can stand the rigorous peer review process. The expectations of standard journals, and common pitfalls the major elements of a manuscript are covered.
An empirical analysis of overlap publication in Chinese language and English research manuscripts.
Directory of Open Access Journals (Sweden)
Joseph D Tucker
Full Text Available BACKGROUND: There are a number of sound justifications for publishing nearly identical information in Chinese and English medical journals, assuming several conditions are met. Although overlap publication is perceived as undesirable and ethically questionable in Europe and North America, it may serve an important function in some regions where English is not the native tongue. There is no empirical data on the nature and degree of overlap publication in English and Chinese language journals. METHODS/PRINCIPAL FINDINGS: A random sample of 100 English manuscripts from Chinese institutions was selected from PubMed. Key words and institutions were searched in the China National Knowledge Infrastructure, a comprehensive Chinese language research database. Unacknowledged overlap was a priori defined according to International Committee of Medical Journal Editor (ICMJE guidelines following examination by two individuals. 19% (95% CI 11-27 of English manuscripts from Chinese institutions were found to have substantial overlap with Chinese published work based on full text examination. None of the manuscripts met all of the criteria established by the ICMJE for an acknowledged overlap publication. Individual-level, journal-level, and institutional factors seem to influence overlap publication. Manuscripts associated with an institution outside of China and with more than one institution were significantly less likely to have substantial overlap (p<0.05. CONCLUSIONS/SIGNIFICANCE: Overlap publication was common in this context, but instances of standard ICMJE notations to acknowledge this practice were rare. This research did not cite the identified overlap manuscripts with the hope that these empirical data will inform journal policy changes and structural initiatives to promote clearer policies and manuscripts.

ON COPIES OF THE MANUSCRIPT OF THE GLAGOLITIC QUARESIMALE

Andrea Radošević
2014-01-01
Full Text Available Studies about the linguistic characteristics of a few Glagolitic manuscript versions of Quaresimale, as well as studies about other texts (The Treatise on the Seven Deadly Sins; Greblo's Commentary on the Passion of Christ that were included in the same manuscripts as the Lenten sermons, have already been published. After the structure of the Glagolitic Quaresimale, that has been preserved in the form of five Glagolitic manuscripts (Kolunić Quaresimale, Quaresimale III a 19, Greblo Quaresimale, Oport Quaresimale, Fatević Miscellany, had been studied, the next step in the research of the Glagolitic Quaresimale was to study the relationship between the written sermons and their performance, because the performance, or orality, is one of the main characteristics of sermons as a genre. The results of this study show that the different places in which the copies of the manuscript were kept, the thematic similarity between the sermons and other texts in manuscripts, as well as the attitude of the scribes towards the graphic design of the text, had influenced the performance of the Lenten sermons. The performances of these Glagolitic sermons reflect a great deal more variety than would be expected on the basis of the content of sermons in all five manuscripts which is very similar.
Strategies for effective collaborative manuscript development in interdisciplinary science teams

Science is increasingly being conducted in large, interdisciplinary teams. As team size increases, challenges can arise during manuscript development, where achieving one team goal (e.g., inclusivity) may be in direct conflict with other goals (e.g., efficiency). Here, we present strategies for effective collaborative manuscript development that draw from our experiences in an interdisciplinary science team writing collaborative manuscripts for six years. These strategies are rooted in six guiding principles that were important to our team: to create a transparent, inclusive, and accountable research team that promotes and protects team members who have less power to influence decision‐making while fostering creativity and productivity. To help alleviate the conflicts that can arise in collaborative manuscript development, we present the following strategies: understand your team composition, create an authorship policy and discuss authorship early and often, openly announce manuscript ideas, identify and communicate the type of manuscript and lead author management style, and document and describe authorship contributions. These strategies can help reduce the probability of group conflict, uphold individual and team values, achieve fair authorship practices, and increase science productivity.

In the pharmaceutical industry, bioanalysis is very dynamic and is probably one of the few fields of research covering the entire drug discovery, development and post-marketing process. Important decisions on drug safety can partially rely on bioanalytical data, which therefore can be subject to regulatory scrutiny. Bioanalytical scientists have historically contributed significant numbers of scientific manuscripts in many peer-reviewed analytical journals. All of these journals provide some high-level instructions, but they also leave sufficient flexibility for reviewers to perform independent critique and offer recommendations for each submitted manuscript. Reviewers play a pivotal role in the process of bioanalytical publication to ensure the publication of high-quality manuscripts in a timely fashion. Their efforts usually lead to improved manuscripts. However, it has to be a joint effort among authors, reviewers and editors to promote scientifically sound and ethically fair bioanalytical publications. Most of the submitted manuscripts were well written with only minor or moderate revisions required for further improvement. Nevertheless, there were small numbers of submitted manuscripts that did not meet the requirements for publications because of scientific or ethical deficiencies, which are discussed in this Letter to the Editor.

The review process is described, and instructions on conducting fair and expeditious manuscript evaluations are provided for reviewers. In addition, a number of special topics are addressed, including potential conflicts of interest for an author, institutional review of experiments that involve human subjects or animals, and the reproduction of photographs and other images in color versus black and white. In summary, this article presents key guidelines to ensure compliance with the principles of sound scientific writing and the expeditious review of manuscripts prepared for publication in peer-reviewed dental journals.
Image Segmentation of Historical Handwriting from Palm Leaf Manuscripts
Surinta, Olarik; Chamchong, Rapeeporn
Palm leaf manuscripts were one of the earliest forms of written media and were used in Southeast Asia to store early written knowledge about subjects such as medicine, Buddhist doctrine and astrology. Therefore, historical handwritten palm leaf manuscripts are important for people who like to learn about historical documents, because we can learn more experience from them. This paper presents an image segmentation of historical handwriting from palm leaf manuscripts. The process is composed of three steps: 1) background elimination to separate text and background by Otsu's algorithm 2) line segmentation and 3) character segmentation by histogram of image. The end result is the character's image. The results from this research may be applied to optical character recognition (OCR) in the future.
Gender trends of urology manuscript authors in the United States: a 35-year progression.
Weiss, Dana A; Kovshilovskaya, Bogdana; Breyer, Benjamin N
2012-01-01
The presence of women in urology has gradually increased in the last 35 years with an accelerated rate in the last decade. We evaluated manuscript authorship trends by gender. Manuscript authorship is a metric that has been used as a marker of academic productivity. We hypothesized that the number of first and last author publications by women has increased proportionately to the number of women in the field during the last 35 years. We performed a bibliometric study to examine authorship gender in The Journal of Urology® and Urology®. We reviewed all original articles published from American institutions in 1974, 1979, 1984, 1989, 1994, 1999, 2004 and 2009. Of the 8,313 articles reviewed 5,461 were from American institutions, including 97.5% for which we determined author gender. There were 767 articles with female authors, including 440 first and 327 last authors. First and last female authorship increased from 2.7% of all authors in 1979 to 26.5% in 2009 (test for trend p authorship rate surpasses the rate of growth of women in urology, which increased from 0.24% in 1975 to 6.2% in 2008. Based on authorship gender analysis women urologists produce manuscripts at a rate that exceeds their number in the field. Findings show that women in urology are productive, active members of the academic community. Copyright © 2012 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Sundanese ancient manuscripts as Sundanese heritage are in damage condition and also the information that containing on it. So in order to preserve the information in Sundanese ancient manuscripts and make them easier to search, a search engine has been developed. The search engine must has good computing ability. In order to get the best computation in developed search engine, three types of probabilistic approaches: Bayesian Networks Model, Divergence from Randomness with PL2 distribution, and DFR-PL2F as derivative form DFR-PL2 have been compared in this study. The three probabilistic approaches supported by index of documents and three different weighting methods: term occurrence, term frequency, and TF-IDF. The experiment involved 12 Sundanese ancient manuscripts. From 12 manuscripts there are 474 distinct terms. The developed search engine tested by 50 random queries for three types of query. The experiment results showed that for the single query and multiple query, the best searching performance given by the combination of PL2F approach and TF-IDF weighting method. The performance has been evaluated using average time responds with value about 0.08 second and Mean Average Precision (MAP) about 0.33.

Among research-focused nursing doctoral (PhD) programs in the United States, the traditional dissertation format has recently given way to a series of publication-ready manuscripts, often bookended by introduction and conclusion chapters. To help programs make decisions about the use of these formats, this study undertook a national survey of programs offering PhDs in nursing. The purpose of this study was to explore the advantages and disadvantages of the traditional format versus manuscript option for dissertations among nursing PhD programs in the United States. Cross-sectional census survey of U.S. nursing PhD programs. A web-based survey was administered to all U.S. nursing PhD programs. Respondents indicated formats offered, factors contributing to decisions of which formats to offer, and lessons learned. Descriptive statistics and inductive content analyses were used for analysis. Of 121 eligible institutions, 79 provided eligible responses (66.7%). The majority (59%) offered both formats; 11% offered the manuscript option only, and 24% offered the traditional format only. Faculty support (or lack thereof) contributed to adoption (or not) of the manuscript option. Respondents' approaches to the manuscript option (e.g., number of papers) and advice are summarized. Manuscript option dissertations are commonly offered and provide benefits to students and faculty; however, thoughtful implementation is critical. Programs need to agree upon clear expectations and have graduate school support (e.g., formatting). Faculty need mentorship in advising manuscript option students who choose to use this format, and the time and support. Finally, students need additional writing skills that could be provided through coursework or via individual work with mentors. As nursing education continues to expand further into doctoral research, programs must examine dissertation formats in order to both prepare future nurse scholars and disseminate nursing research that is critical

Full Text Available Are the surviving copies of schooltexts representative of what was popularly used in schools in the medieval period? In other words, was the survival of these manuscripts a random or selective process? To approach this question, this article presents a series of comparisons between the numbers of manuscripts of different schooltexts. It demonstrates that the most popular schooltexts all survive in very similar numbers from each century, and that the typical number of copies varies from one century to another. The easiest explanation for such a survival pattern is to assume that the texts were produced in equal numbers and passed through a relatively random filter of losses. The article seeks to test this intuitive explanation by using a simple probability mathematical experiment. In addition, the article analyses how the numbers of surviving manuscripts relate to entries in medieval book lists and medieval library catalogues. This examination supports the interpretation that the survival of schooltexts was a relatively random process. In addition, comparison between medieval book lists and extant manuscripts advocates caution in using the book lists as evidence for the popularity of texts in the medieval centuries. Even though the catalogues provide snapshots of specific historical situations, this paper concludes that the mass of extant books is more likely to give us a realistic picture of the contemporary popularity of texts.
[Illustrations of of alchemy vessels in a manuscript of Pseudo-Geber].
Kurzmann, Peter
2011-01-01
Manuscript ric. 933 "Geber de investigatione perfectionis magisterii", kept in the Libreria Riccardiana in Florence, is a 13th century Latin version of the "Book of the Secret of the Secrets" ("kitab sirr al-asrar") by the Arabian alchemist al-Razi (865-925). The manuscript shows on page 25r a series of drawings of alchemistic vessels and apparatus which do not figure in the Arabian original but which are of particular interest as they date from as early as the 13th century and are numbered amongst the earliest drawings of this kind which we possess. The publication of the manuscript by Julius Ruska in 1935 shows only copied drawings with his interpretations of the legends. There was considerable interest in the publication of the original page 25r and in the course of further study it became clear that these interpretations had to be revised. These new interpretations presented in detail in this paper are justified and put into an alchemistic context. In some cases they give a new understanding and differ considerably from Ruska's versions.

The aim of this research is to establish an effective procedure of iron gall ink characterization using complementary non-destructive methods. By this, it is possible to better understand correlation of chemical composition of the inks and the state of preservation of iron gall ink manuscripts, as well as the effects of conservation treatment performed upon them. This study was undertaken on a bound 16th century manuscript comprised of different types of paper and ink from the National and University Library in Zagreb. Analytical methods used included Particle Induced X-ray Emission (PIXE) and X-ray Fluorescence (XRF). Paper fibers were identified by optical microscopy and the degradation state, as well as ink differentiation, transit metal migrations and detection of stains, with ultraviolet (UV) and infrared (IR) photography. The techniques applied on original writing materials gave important information about paper and ink composition, its preservation state and efficiency of conservation treatment performed upon them.
On the identification of folium and orchil on illuminated manuscripts.
Aceto, Maurizio; Calà, Elisa; Agostino, Angelo; Fenoglio, Gaia; Idone, Ambra; Porter, Cheryl; Gulmini, Monica
2017-01-15
The identification of the two purple dyes folium and orchil has rarely been reported in the analysis of painted artworks, especially when analysing illuminated manuscripts. This is not consistent with the fact that ancient literary sources suggested their use as substitutes for the more expensive Tyrian purple dye. By employing non-invasive spectroscopic techniques, the present work demonstrates that these dyes were actually widely used in the production of ancient manuscripts. By employing UV-visible diffuse reflectance spectrophotometry with optic fibres (FORS) and spectrofluorimetry, the abundant identification of both dyes on medieval manuscripts was performed by comparing the spectra recorded on ancient codices with those obtained on accurate replicas of dyed or painted parchment. Moreover, examples are also reported whereby the considered purple dyes were used in mixtures with other colourants. The overall information obtained here allowed us to define new boundaries for the time range in which orchil and folium dyes were used which is wider than previously thought, and to focus on their particular uses in the decoration of books.

The changing focus within medical and allied health disciplines towards evidence-based practice has resulted in an increasing acceptance of research and professional researchers. Despite the shift towards tertiary degree-based training for medical imaging and allied specialty streams, with many teaching institutions now incorporating compulsory research components into their final year curriculum, the level of active involvement in research among graduates remains low. In addition to this, many of those who completed their training before the introduction of university degree courses have had little or no exposure to hands-on research. While not overtly difficult, the process of 'writing up' the findings of a research endeavour for presentation to peers can often seem a somewhat daunting task, especially for novice researchers. The structure of a scientific manuscript however follows a relatively basic and universally accepted pattern, adherence to which can greatly simplify the writing process. To contribute to a wider understanding of research, the purpose of this paper is to provide an overview of the basic elements of a scientific research paper for journal publication. The outline provided, while not intended to be a recipe for manuscript construction, will provide a fundamental framework to assist student, junior or inexperienced researchers in their writings
BIBLICAL MOTIFS IN THE UNDERSTANDING THE MANUSCRIPTS OF A SCRIBE FROM PECHORA I. S. MYANDIN

Miandin (1823–1894, Ust’-Tsilma, Komi Republic from the Old Manuscript Division of the IRLI (Institute of Russian Literature of the Russian Academy of Science or Pushkinskiy Dom. Knizhnik, in the Russian tradition, is a scribe, who also can recite from memory the Scripture texts and the patristic tradition. Miandin left his recapitulations of the Old Believers literary tradition. He left few compilations, transcribed a number of Old Russian texts of various genres. In four convolutes, he collected Biblical stories taken from chronographs. Most of Miandin’s stories recapitulate the Old Testament texts, but there are also legends from the early Christian history (e. g., The Story of Emperor Constantine and His Mother Helen. His major source was, in all probability, the copy of the Chronograph from the Old Believers tradition which he had in his possession (he lent it to a writer S. V. Maksimov and never received it back. The whereabouts of the Chronographer are not known. Some of the stories were signifi cantly reworked by Miandin in comparison with the chronographic version. Among those the are the stories of Joseph the Beautiful, King Solomon and Judith. Th e study of Miandin’s manuscripts demosntrates that the fi rst stage of his work is refl ected in the IRLI reduction (Ust’-Tsil’ma collection #267, the second – idem, #66, the third – RNB NSRK О.100. The Biblical protagonists were interpreted according to the understanding of life by Pechora peasants. The peripeteias were taken with empathy as if they were concerned people next-door. This attitude compelled the narrator to seek, from one version to another, the most convincing motivations for the action of the heroes.

[Regarding the Manuscript D " Dell' occhio " of Leonardo da Vinci].
Heitz, Robert F
2009-01-01
Leonardo da Vinci's Manuscript D consists of five double pages sheets, which, folded in two, comprise ten folios. This document, in the old Tuscan dialect and mirror writing, reveals the ideas of Leonardo on the anatomy of the eye in relation to the formation of images and visual perception. Leonardo explains in particular the behavior of the rays in the eye in terms of refraction and reflection, and is very mechanistic in his conception of the eye and of the visual process. The most significant innovations found in these folios are the concept of the eye as a camera obscura and the intersection of light rays in the interior of the eye. His texts nevertheless show hesitation, doubts and a troubled confusion, reflecting the ideas and uncertainties of his era. He did not share his results in his lifetime, despite both printing and etching being readily available to him.
Navigating manuscript assessment: The new practitioner's guide to primary literature peer review.
Smith, Devlin V; Stokes, Laura B; Marx, Kayleigh; Aitken, Samuel L
2018-01-01
For pharmacists, the first years after graduation are spent developing their knowledge base, advancing as a practitioner, and honing their abilities as healthcare providers and drug information experts. New practitioners encounter many challenges during this time, which for many include publishing original research or reviewing manuscripts for colleagues and medical journals. Inexperience navigating the publication process, from submission to receipt of (and response to) peer review commentary, is often cited as a major barrier to timely publication of resident and new practitioner research. Serving as a peer reviewer in turn provides the new practitioner with insight on this process and can be an enlightening experience used to garner confidence in subsequently submitting their own formal manuscripts. A number of publications describing steps for peer review are available, however, many of these articles address more experienced reviewers or critique the peer review process itself. No definitive resource exists for new pharmacy practitioners interested in developing their peer review skills. The information presented in this summative guide should be used in conjunction with practice opportunities to help new practitioners develop proficiency at peer review.

The objective of our study was to investigate radiology manuscript characteristics that influence citation rate, capturing features of manuscript construction that are discrete from study design. Consecutive articles published from January 2004 to June 2004 were collected from the six major radiology journals with the highest impact factors: Radiology (impact factor, 5.076), Investigative Radiology (2.320), American Journal of Neuroradiology (AJNR) (2.384), RadioGraphics (2.494), European Radiology (2.364), and American Journal of Roentgenology (2.406). The citation count for these articles was retrieved from the Web of Science, and 29 article characteristics were tabulated manually. A point-biserial correlation, Spearman rank-order correlation, and multiple regression model were performed to predict citation number from the collected variables. A total of 703 articles-211 published in Radiology, 48 in Investigative Radiology, 106 in AJNR, 52 in RadioGraphics, 129 in European Radiology, and 157 in AJR-were evaluated. Punctuation was included in the title in 55% of the articles and had the highest statistically significant positive correlation to citation rate (point-biserial correlation coefficient [r pb ] = 0.85, p radiology. Using bibliometric knowledge, authors can craft a title, abstract, and text that may enhance visibility and citation count over what they would otherwise experience.

There was a dramatic increase in the volume of manuscripts submitted to The Journal of Bone & Joint Surgery (JBJS) between 2009 and 2012. This resulted in increased journal administrative costs. To offset this financial burden, in May 2013, JBJS started charging authors an administrative processing fee at the time of submission. The purpose of this study was to assess the impact of the administrative fee on the volume and characteristics of manuscripts submitted to JBJS. Our analysis included 866 manuscripts submitted to JBJS between November 2012 and November 2013. We compared manuscripts submitted 6 months prior to fee implementation and prior to the announcement (denoted as the baseline group), in the several months prior to fee implementation but after the fee implementation announcement (denoted as the fee announcement group), and in the 6 months after fee implementation (denoted as the fee implementation group). Manuscripts were reviewed for institutional and author demographic characteristics, as well as for general study characteristics. In the first full calendar year (2014) after the implementation of the fee, the annual volume of submissions to JBJS declined by 33.5% compared with the annual submission volume in 2010 to 2012. In a comparative analysis, the geographical region of origin (p = 0.003), level of evidence (p Reporting of funding information improved significantly between the baseline and fee implementation groups; in the post-fee implementation period, studies were more likely to have declared no external funding source (p = 0.001). The administrative processing fee at JBJS has been associated with a decrease in submission volume, but, overall, there has not been a change in the characteristics of studies submitted. However, decreased overall volume implies a decrease in the absolute number of high-level studies submitted to the journal. Administrative processing fees at high-volume journals may be a financially viable way to offset high
Integration of μ-XRF, and u-Raman techniques to study ancient Islamic manuscripts

Hamdan, N M; Alawadhi, H; Jisrawi, N
2012-01-01
Systematic characterizations of inks used in three ancient Arabic manuscripts were performed using energy dispersive X-ray fluorescence (EDXRF) and RAMAN spectroscopy. Spatially resolved element distributions obtained by area scans in addition to spot analysis provided detailed information about the manuscripts. RAMAN spectroscopy, on the other hand provided decisive information about the compounds used in various color pigments. Different compounds were found in the red ink in each manuscript: HgS (cinnabar) in one manuscript, red lead Pb 3 0 4 (minium) in the second, and a mixture of the two in the third manuscript. The green pigment was Cu based and it is probably malachite (Cu 2 CO 3 (OH) 2 ), while the black ink pigment in the three manuscripts is iron gall (Fe 2 SO 4 plus gallottanic acid). Analytical results and the context of the manuscripts were used to extract information about the authenticity and origin of the manuscripts. For example, the use of cinnabar as a red ink pigment found in the third manuscript reveals that this manuscript attributed to Al-Gazali (11 th century) is probably a copy from a later period, because cinnabar was first introduced in the 16th century.
Manuscript 101: A Data-Driven Writing Exercise For Beginning Scientists

Learning to write a scientific manuscript is one of the most important and rewarding scientific training experiences, yet most young scientists only embark on this experience relatively late in graduate school, after gathering sufficient data in the lab. Yet, familiarity with the process of writing a scientific manuscript and receiving peer reviews, often leads to a more focused and driven experimental approach. To jump-start this training, we developed a protocol for teaching manuscript writ...

Better understanding of the reasons why manuscripts are rejected, and recognition of the most frequent manuscript flaws identified by reviewers, should help submitting authors to avoid these pitfalls. Of 219 manuscripts submitted to Veterinary Radiology & Ultrasound in 2012, none (0%) was accepted without revision, four (2%) were withdrawn by the authors, 99 (45%) were accepted after revision, and 116 (53%) were rejected. All manuscripts for which minor revision was requested, and 73/86 (85%) manuscripts for which major revision was requested, were ultimately accepted. Acceptance rate was greater for retrospective studies and for manuscripts submitted from countries in which English was the primary language. The prevalences of flaws in manuscripts were poor writing (62%), deficiencies in data (60%), logical or methodological errors (28%), content not suitable for Veterinary Radiology & Ultrasound (26%), and lack of new or useful knowledge (25%). Likelihood of manuscript rejection was greater for lack of new or useful knowledge and content not suitable than for other manuscript flaws. The lower acceptance rate for manuscripts from countries in which English was not the primary language was associated with content not suitable and not poor writing. Submitting authors are encouraged to do more to recognize and address manuscript flaws before submission, for example by internal review. Specifically, submitting authors should express clearly the potential added value of their study in the introduction section of their manuscript, describe completely their methods and results, and consult the Editor-in-Chief if they are uncertain whether their subject matter would be suitable for the journal. © 2014 American College of Veterinary Radiology.

Should copyright be transferred before a manuscript is accepted?
Teixeira da Silva, Jaime A
2017-10-01
Academic journals that undergo a process of academic scrutiny often pass a stage of peer review and subsequent editorial approval. In a process that can take weeks or months (in some cases, even years), an author aims to satisfy the requirements of peer reviewer and editorial scrutiny that would merit publication of their work. It is customary to, in traditional, non-open access journals, to then sign over copyright to the publisher, upon which the publisher then issues a proof, and the manuscript is then published. Even though it is obvious that an author would not submit to a journal with the objective of having it rejected, the issue of the timing of copyright transfer is one which does not appear to have been discussed in the literature, possibly because the order of transfer, i.e., after acceptance of a paper for publication, seems naturally logical. With the modernization of online submission systems, the transfer of copyright tends to occur online, after acceptance. However, on occasion, some journals request the transfer of copyright before peer review and editorial processing occurs, i.e., upon the act of submission. This letter examines three cases of Springer Nature plant science journals that demand the transfer of copyright to the journal's society upon submission, in direct violation of their instructions for authors. Authors have no right to challenge this discrepancy, nor can they complete submission in accordance with the instructions for authors because they are forced to submit copyright upon submission. Not only does transfer of copyright at such an early stage of the publishing process constitute a waste of authors' time-a precious commodity in a cut-throat field of science-in the three cases indicated in this paper, they may constitute a violation of authors' rights. The ethics of this request by the journals and publisher need to be debated.

The Constabulus manuscript in Durham Cathedral Library: A Forgotten Treasure?
Directory of Open Access Journals (Sweden)
Robinson, Maureen

Full Text Available Johannes Hispalensis (John of Seville, working from Limia in Portugal and then Toledo in twelfth century Spain, translated mostly mathematical treatises from Arabic into Latin. His early work began in Limia with three medical translations c. 1118. One, the De differentia spiritus et animae originally bore the signature 'Johannes Hispalensis et Limiensis'. Not all scholars agree that this translator was Johannes Hispalensis. However, evidence supporting the theory that there was only one translator is provided by the De differentia, which resurfaced years later in a revised version dedicated to Raymond, Archbishop of Toledo from 1125 to 1152. It bore the shortened name: Johannes Hispalensis. An unknown copy of this revised version has been discovered in Durham Cathedral where it has lain dormant for 800 years. It contains a plethora of scribal mistakes, helping to prove that many of the inconsistencies between different copies of the same Latin manuscripts are due to human error rather than multiple identities working on the same translation.

Padua and the Stars: Medieval Painting and Illuminated Manuscripts
Canova, G. M.
2011-06-01
In the Middle Ages, the University of Padua was one of the most prominent centre for astrological studies in Europe. The Paduan doctor and philosopher, Pietro d'Abano, who lived in the first decades of the 14th century, was the main figure in this field. At the end of the 13th century, during a long stay in Paris, he got in contact with the new astrological doctrines flourished after the translation into Latin of Ptolemy's and Arab's works in Spain. Thus, when he went back to Padua, he published several studies on the influence of celestial bodies on human life and human physical characteristics and psychology. These ideas deeply affected the Paduan society of the 14th century and, consequently, the most important painters chose or were asked to evoke the images of stars, planets, and their properties. This adventure began with Giotto who shows a surprising interest in celestial bodies in the Scrovegni Chapel where he represented a comet, and soon after he produced a cycle of astrological paintings on the vault of the Palazzo della Ragione in the Public Palace of Padua. Unfortunately, in 1420, these paintings were destroyed in a fire, but the magnificent cycle of astrological frescoes realized soon after on the walls of the same room gives us some clues on Giotto's work and shows us the complexity of the Medieval astrological science. Other astrological paintings, still preserved, were realized by the painters of the Carrarese Court such as Guariento, who painted the planets and their influences on human ages in the church of the Eremitani, and Giusto dei Menabuoi who represented a superb zodiac around a realistic map of Earth in the Cathedral Baptistery. So Padua really became the capital of astrological painting in Europe. Other evidence of the astrological image in the Veneto Region, between the 14th and 15th centuries, can be found in the manuscripts illuminated in the milieu of the University of Padua and in the first books printed in Venice.

This study relates, describes, analyzes & comments the content of a recently discovered old manuscript, written probably at the beginning of the 18th century, and compares it with the well known "Long life Elixir, or Swedish Elixir", manuscript found on a Swedish doctor who died at 104 years old as a result of a fall from his horse... The origin of this new manuscript can be established from 1700 to 1710, and seems to be probably anterior to the well known Swedish manuscript, meanwhile the text is almost similar,... and also is more complete than this one! We learn that the "Manna" is synonymic here of "fine Rhubarb". Another recipe, unknown on the other manuscript and titled "Dalibour Water" is also published: By similar way, this formula brings some new details, in particular in the exact composition, the preparation and the use of the "Long Life Elixir".
If At First You Don't Succeed: The Fate of Manuscripts Rejected by Academic Emergency Medicine.
Grant, William D; Cone, David C
2015-10-01
The purpose of this study was to characterize the publication fate of a recent 2-year sample of manuscripts declined by Academic Emergency Medicine (AEM), the journal of the Society for Academic Emergency Medicine. This was a retrospective analysis of manuscripts submitted to AEM in 2010 and 2011 that were declined by the AEM editorial review process. An online search was conducted for each declined paper, to determine whether or not it was published in another clinical/scientific journal after being declined by AEM. The investigators used Scopus and Google Scholar, using the submitting author's name, the verbatim title, and key words and phrases from the title, to search for subsequent publication of each paper. Of 1,542 manuscript submissions to the journal in 2010 and 2011, 1,052 papers were declined. Of these, 693 (65.9%) were subsequently published elsewhere, in a total of 229 journals: 362 papers in 22 different EM journals, 81 in 14 EM subspecialty journals, 237 in 185 non-EM journals, and 13 in eight nursing journals. Papers were published a median of 16.7 months (interquartile range [IQR] = 11.8 to 22.0 months) after being declined at AEM. Of the 229 journals, 19 do not have h-indices. The median h-index of the remaining 210 journals is 36 (IQR = 17 to 64; maximum = 229; AEM's h-index is 78). Thirty of these 210 journals, publishing 43 papers, have higher h-indices than AEM; the other 650 papers were published in journals either with lower h-indices than AEM's (n = 180 journals) or in journals without h-indices (n = 19 journals). U.S. and non-U.S. authors had similar rates of subsequent publication (65.3% vs 66.6%, p = 0.69) for papers initially declined by AEM. Papers in the educational advances category were less likely to be subsequently published than those in the original contributions (p journal are eventually published elsewhere, in a large number and wide variety of both EM and non-EM journals, in a median of 16.7 months.

Full Text Available In the field of international scholarly journal publishing, manuscript editing has been established as an essential component of the publication process. As the necessity of this process has increased, the Korean Council of Science Editors has consistently provided education for training professional manuscript editors, and has worked to implement a manuscript editor certification system. Starting in 2014, the Korean Council of Science Editors thoroughly conducted background research and advanced analysis in preparation for such a system. Subsequently, a committee of experts was formed to develop and simulate an examination for this certification. This process culminated in the first manuscript editor certification examination, which was held in November 2016 and resulted in 40 initial Korea Manuscript Editors Certification holders. Examinations for the Korea Manuscript Editors Certification are scheduled to be held annually. The establishment of this certification system will contribute to strengthening individual capacities and further developing science journal publication in Korea by expanding the field of manuscript editing. Ultimately, this system will contribute to the promotion of Korean scientific journals to the level of prominent international journals.
Implementation and Outcomes of a Faculty-Based, Peer Review Manuscript Writing Workshop.
Kulage, Kristine M; Larson, Elaine L
2016-01-01
The publication of scholarly work and research findings is an important expectation for nursing faculty; however, academic writing is often neglected, leaving dissemination through manuscript writing an area of concern for the nursing profession. Writing initiatives have been utilized to promote scholarly dissemination in schools of nursing, but those described in the literature have been primarily non-United States based and student focused. This article describes a faculty-based manuscript writing workshop, assesses participants' impressions, and describes its impact on scholarly output. The workshop is a collaborative learning process utilizing peer review to improve manuscript quality and model behaviors for improving writing and peer-reviewing skills. Seventeen workshop participants including three predoctoral students, 6 postdoctoral fellows, and 8 faculty members completed an anonymous workshop survey (81% response rate). All but 1 of 17 manuscripts reviewed in the workshop are published, accepted, or in the review process. All participants indicated that the workshop was a valuable use of time and would recommend it to colleagues. The greatest reported workshop benefit was its function as an impetus to complete and submit manuscripts. We recommend the manuscript writing workshop model for other schools of nursing seeking ways to expand their scholarly output and create accountability for dissemination through manuscript writing.

At the present stage of the investigation, some of the poems have not been confirmed to have been published earlier. An anonumous 12-verse poem without a title, attached to the communique at full length, has been identified by the author of the article as a poem whose last four verses were published in 1881 in the book Kraków — Zagrzebiowi under the title W albumie księcia Golicyna by Adam Mickiewicz. The article is intended to stimulate those engaged in research of the history of literature in further investigations concerning the said collection of poems, in particular the last mentioned text.
Where should I publish my next manuscript on Limnology?

Full Text Available Abstract When we need to spread the limnological knowledge, arises an issue that is not less than: where to publish our next article? In recent decades, the main element of evaluation are the “papers” and the sentence “publish or perish” haunts many scientists. It is imperative that researchers to share their discoveries or new knowledge. The dilemma arises because the scientific agencies (led by scientists have installed what I call prestige system in which researchers needs a number of articles published in mainstream journals with highest positions in the ranking to progress in their scientific carrier. This determines a strong pressure on the subjects under investigation, in the allocation of resources and, sometimes, comes to desperation to publish. It is also producing the neglect of regional issues hardly find place in those journals and end up published in journals unreliable. The dissemination of the limnological topics in Latin American journals gradually lost prominence. In my opinion, it´s necesary to spread the results for the people that paying our salaries and supports our projects. Put another way, publish in good local journals, without prejudice to also publish in journals of high international ranking. Scientific production should be evaluated for their trascendence, by his transforming power and not just by impact factors used today by many agencies.

At every academical platform on medical history and its instruction, lack of Turkish medical historiography is mainly emphasized. There are two main factors determining the situation: 1-There isn't any comprehensive Turkish medical history textbook. 2-There are difficulties in reaching the primary sources in this field. Everybody agrees with the importance of reaching medical manuscripts easily and reading and evaluating them in medical history. For this reason, it is important to know where we can find them. In this article, medical manuscripts which are available in the library of the Deontology Department of Ankara University Medical School are introduced. The manuscripts have been listed in alphabetical order of the authors' name. The bibliographic items, such as the size, writing style, and type of paper used, are mentioned.

Teaching How to Prepare a Manuscript by Means of Rewriting Published Scientific Papers
Tomaska, Lubomir
2007-01-01
The objective of the course described here is to train undergraduate students to write a scientific manuscript. The students participate in selection of a current topic in contemporary genetics or molecular biology by choosing the most interesting paper of a given year. After the teacher provides all essential background about the selected subject, he or she selects a recent article from the corresponding field and presents the students with all the necessary information contained in the paper without revealing its title and author. The data presented in the paper are reviewed by the class so that each student understands every experiment and the main points of the work. Simultaneously, the students are informed about the basic rules of writing the individual sections of a scientific paper. They are then asked to write and formally submit a manuscript summarizing the data. Finally, the students act as reviewers of their colleagues' manuscripts and compare their papers with the original published articles. This enables them to identify both the strengths and the weaknesses of their manuscripts and to gain confidence in the writing skills that will be so critical for their future scientific activities.

Household Scribes and the Production of Literary Manuscripts in Early Modern England
Directory of Open Access Journals (Sweden)
Marcy L. North
2015-03-01
Full Text Available In early modern English households, literate servants such as tutors, chaplains, stewards, secretaries, and ladies in waiting were well positioned to assist their employers in the assembly and copying of verse miscellanies, anthologies, and other literary manuscripts. Looking at several literary manuscripts, some with known servant contributions and others that suggest the participation of household retainers, the essay explores the likelihood that literate servants often performed scribal tasks above and beyond their formal job descriptions, even serving as scribe for their employers’ hobbies and leisure activities. Although copying was an arduous task, servants appear to have viewed these duties not simply as part of their job but also as gift exchanges, as appeals for promotion or patronage, and as a means by which they might gain access to manuscript literature and literary circles. Studies of early modern letter writing have called attention to many of the copy tasks of literate household servants, but the integral role of literate servants in the collection, copying, and preservation of literary manuscripts deserves much more attention.

Full Text Available The timely publication of scientific results is essential for dynamic advances in science. The ubiquitous availability of computers which are connected to a global network made the rapid and low-cost distribution of information through electronic channels possible. New concepts, such as Open Access publishing and preprint servers are currently changing the traditional print media business towards a community-driven peer production. However, the cost of scientific literature generation, which is either charged to readers, authors or sponsors, is still high. The main active participants in the authoring and evaluation of scientific manuscripts are volunteers, and the cost for online publishing infrastructure is close to negligible. A major time and cost factor is the formatting of manuscripts in the production stage. In this article we demonstrate the feasibility of writing scientific manuscripts in plain markdown (MD text files, which can be easily converted into common publication formats, such as PDF, HTML or EPUB, using Pandoc. The simple syntax of Markdown assures the long-term readability of raw files and the development of software and workflows. We show the implementation of typical elements of scientific manuscripts—formulas, tables, code blocks and citations—and present tools for editing, collaborative writing and version control. We give an example on how to prepare a manuscript with distinct output formats, a DOCX file for submission to a journal, and a LATEX/PDF version for deposition as a PeerJ preprint. Further, we implemented new features for supporting ‘semantic web’ applications, such as the ‘journal article tag suite’—JATS, and the ‘citation typing ontology’—CiTO standard. Reducing the work spent on manuscript formatting translates directly to time and cost savings for writers, publishers, readers and sponsors. Therefore, the adoption of the MD format contributes to the agile production of open science

Young hands, old books: Drawings by children in a fourteenth-century manuscript, LJS MS. 361.
Thorpe, Deborah Ellen
This article scrutinises three marginal drawings in LJS 361, Kislak Center for Special Collections, Rare Books and Manuscripts, University of Pennsylvania Libraries. It first considers the provenance of the manuscript, questioning how it got into the hands of children. Then, it combines developmental psychology with close examination of the material evidence to develop a list of criteria to attribute the drawings to children. There is consideration of the features that help us estimate the age of the artists, and which indicate that one drawing was a collaborative effort between two children. A potential relationship is identified between the doodles and the subject matter of the text, prompting questions about pre-modern child education and literacy. Finally, the article considers the implications of this finding in both codicology and social history since these marginal illustrations demonstrate that children were active in the material life of medieval books.

The Bleek and Lloyd Manuscripts are an extraordinary resource that comprises some 12 000 pages of |xam Bushman beliefs collected in the 1870s in Cape Town, South Africa. About 17% of the collection concerns beliefs and observations of celestial bodies. This paper summarises |xam knowledge about the origins of the celestial bodies as recorded in the manuscripts and situates this within the larger context of the |xam worldview. The stars and planets originate from a mythological past in which they lived as 'people' who hunted and gathered as the |xam did in the past, but who also had characteristics that were to make them the entities that we recognise today. Certain astronomical bodies have consciousness and supernatural potency. They exert an influence over people's everyday lives.
Strategies for Using Plagiarism Software in the Screening of Incoming Journal Manuscripts

In recent years, several online tools have appeared capable of identifying potential plagiarism in science. While such tools may help to maintain or even increase the originality and ethical quality of the scientific literature, no apparent consensus exists among editors on the degree of plagiarism...... or self-plagiarism necessary to reject or retract manuscripts. In this study, two entire volumes of published original papers and reviews from Basic & Clinical Pharmacology & Toxicology were retrospectively scanned for similarity in anonymized form using iThenticate software to explore measures...... to predictively identify true plagiarism and self-plagiarism and to potentially provide guidelines for future screening of incoming manuscripts. Several filters were applied, all of which appeared to lower the noise from irrelevant hits. The main conclusions were that plagiarism software offers a unique...

2005-06-01
Full Text Available Abstract Background Although scientific writing plays a central role in the communication of clinical research findings and consumes a significant amount of time from clinical researchers, few Web applications have been designed to systematically improve the writing process. This application had as its main objective the separation of the multiple tasks associated with scientific writing into smaller components. It was also aimed at providing a mechanism where sections of the manuscript (text blocks could be assigned to different specialists. Manuscript Architect was built using Java language in conjunction with the classic lifecycle development method. The interface was designed for simplicity and economy of movements. Manuscripts are divided into multiple text blocks that can be assigned to different co-authors by the first author. Each text block contains notes to guide co-authors regarding the central focus of each text block, previous examples, and an additional field for translation when the initial text is written in a language different from the one used by the target journal. Usability was evaluated using formal usability tests and field observations. Results The application presented excellent usability and integration with the regular writing habits of experienced researchers. Workshops were developed to train novice researchers, presenting an accelerated learning curve. The application has been used in over 20 different scientific articles and grant proposals. Conclusion The current version of Manuscript Architect has proven to be very useful in the writing of multiple scientific texts, suggesting that virtual writing by interdisciplinary groups is an effective manner of scientific writing when interdisciplinary work is required.
A propaganda index for reviewing problem framing in articles and manuscripts: an exploratory study.
Gambrill, Eileen; Reiman, Amanda
2011-01-01
To determine the effectiveness of an index in increasing recognition of misleading problem framing in articles and manuscripts. A propaganda index consisting of 32 items was developed drawing on related literature. Seventeen subjects who review manuscripts for possible publication were requested to read five recent published reports of randomized controlled trials concerning social anxiety and to identify indicators of propaganda (defined as encouraging beliefs and actions with the least thought possible). They then re-read the same five articles using a propaganda index to note instances of propaganda. Convenience sample of individuals who review manuscripts for possible publication and sample of recent published reports of randomized controlled trials regarding social anxiety in five different journals by different authors, blinded by author and journal. Data showed that there was a high rate of propagandistic problem framing in reports of RCTs regarding social anxiety such as hiding well argued alternative views and vagueness. This occurred in 117 out of 160 opportunities over five research reports. A convenience sample of 17 academics spotted only 4.5 percent of propaganda indicators. This increased to 64 percent with use of the 32 item propaganda index. Use of a propaganda index increased recognition of related indicators. However many instances remained undetected. This propaganda index warrants further exploration as a complement to reporting guidelines such as CONSORT and PRISMA.
Probing the statistical properties of unknown texts: application to the Voynich Manuscript.

While the use of statistical physics methods to analyze large corpora has been useful to unveil many patterns in texts, no comprehensive investigation has been performed on the interdependence between syntactic and semantic factors. In this study we propose a framework for determining whether a text (e.g., written in an unknown alphabet) is compatible with a natural language and to which language it could belong. The approach is based on three types of statistical measurements, i.e. obtained from first-order statistics of word properties in a text, from the topology of complex networks representing texts, and from intermittency concepts where text is treated as a time series. Comparative experiments were performed with the New Testament in 15 different languages and with distinct books in English and Portuguese in order to quantify the dependency of the different measurements on the language and on the story being told in the book. The metrics found to be informative in distinguishing real texts from their shuffled versions include assortativity, degree and selectivity of words. As an illustration, we analyze an undeciphered medieval manuscript known as the Voynich Manuscript. We show that it is mostly compatible with natural languages and incompatible with random texts. We also obtain candidates for keywords of the Voynich Manuscript which could be helpful in the effort of deciphering it. Because we were able to identify statistical measurements that are more dependent on the syntax than on the semantics, the framework may also serve for text analysis in language-dependent applications.
The Appreciation and Study of Qur’an Manuscripts from Southeast Asia: Past, Present, and Future

Full Text Available The focus of this paper is not on theological aspects of the Qur’an, or on the study of the Qur’anic sciences in Southeast Asia over the past centuries, but rather to attempt to trace the path of the appreciation of old copies of the Qur’an in Southeast Asia as part of the historical record of the Islamic heritage of the region. In this light, Qur’an manuscripts are viewed as objects of material culture which can cast light on the societies which produced them, and as works of art which testify to the heights of artistic creativity in the region, for illuminated Qur’an manuscripts represent the pinnacle of achievements in the arts of the book in Southeast Asia. This historical record can be measured through a survey of how, where, when and by whom Qur’an manuscripts in Southeast Asia were collected, documented, studied and published, both in Southeast Asia itself and in the west.

Full Text Available The exhaustive comparison between Portuguese and the main modern languages is a late phenomenon. Only at the end of seventeenth century, did Portugal feel the need for a methodical learning of foreign languages and for didactic tools with a marked lexical component, in which we include the essential bilingual dictionaries. Nevertheless, it is in the first half of the eighteenth century that the first glossaries are published, while the first bilingual dictionaries with alphabetical order and an extensive nomenclature will appear only in the second half of the century. In order to overcome this lag, Vernacular-Latin dictionaries were imported and handwritten dictionaries were compiled and adapted according to the needs of each user. Research on the origins of Portuguese-Italian lexicography has provided important information on the development of the techniques used to compile dictionaries and the contrastive analysis of languages. The first printed dictionary is an addition to Caetano de Lima’s Grammatica Italiana (1734 and it contains an appendix of hard words (where semantic peculiarities and idiomatic expressions are explained and an onomasiologic dictionary of common words. It has been described as a basic albeit functional lexicographic tool, suitable for beginners’ needs. Recently, a manuscript version of this dictionary has been identified (Diccionario de Nomes Portuguezes e Italianos Dispostos por Materias, Biblioteca Pública de Évora, CXIII-1-33, as well as the manuscript of a larger general dictionary (Diccionario Italiano-Portuguez, Biblioteca Nacional de Portugal, cod. 3342. This impressive lexicographic corpus is compiled about fifty years before the first printed Italian-Portuguese dictionary. The analysis demonstrates that the author tried to compile a much wider dictionary than the version that was actually published. In the manuscript, we can identify problems in some areas, such as the definition of lexical domains (due

This work focused on the application of the most relevant spectroscopic techniques used for the characterization of illuminated manuscripts. The historical value of these unique and invaluable artworks, together with the increased awareness concerning the conservation of cultural heritage, prompted the application of analytical techniques to the study of these illuminations. This is essential for the understanding of the artist's working methods, which aids conservation–restoration. The characterization of the pigments may also help assign a probable date to the manuscript. For these purposes, the spectroscopic techniques used so far include those that provide information on the elemental content: X-ray fluorescence, total reflection X-ray fluorescence and scanning electron microscopy coupled with energy-dispersive spectroscopy and laser-induced breakdown spectroscopy. Complementary techniques, such as X-ray diffraction, Fourier transform infrared and Raman spectroscopy, reveal information regarding the compounds present in the samples. The techniques, suitability, technological evolution and development of high-performance detectors, as well as the possibility of microanalysis and the higher sensitivity of the equipment, will also be discussed. Furthermore, issues such as the necessity of sampling, the portability of the equipment and the overall advantages and disadvantages of different techniques will be analyzed. - Highlights: ► The techniques used for studying illuminated manuscripts are described and compared. ► For in situ, non-destructive analysis the most suitable technique is EDXRF. ► For quantitative analysis TXRF is more appropriate. ► Raman spectroscopy is mostly used for pigments identification. ► FTIR was used for the characterization of binders and parchment.

to assess the conversion rate of Plastic Surgery meeting abstract presentations to full manuscript publications and examine factors associated with this conversion. we assessed the abstracts presented at the 47th and 48th Brazilian Congresses of Plastic Surgery by cross-referencing with multiple databases. We analyzed the Abstracts' characteristics associated with full manuscript publications. of the 200 abstracts presented, 50 abstracts were subsequently published in full, giving the conference a conversion rate of 25%. The mean time to publish was 15.00±13.75 months. In total, there were 4.93±1.63 authors per abstract and 67.8±163 subjects per abstract; 43.5% of the abstracts were of retrospective studies; 69% comprised the plastic surgery topics head and neck, and chest and trunk, and 88.5% had no statistical analysis. Overall, 80% of the manuscripts were published in plastic surgery journals, 76% had no impact factor and 52% had no citations. Bivariate and multivariate analyses revealed the presence of statistical analysis to be the most significant (previstas de Cirurgia Plástica, 76% não exibiam fator de impacto e 52% não possuíam citações. As análises bivariada e multivariada revelaram que a presença de análise estatística foi o fator preditivo significativo (p<0,05) para a conversão de resumos em manuscritos completos. a taxa de conversão deste estudo bibliométrico foi inferior à tendência de conversão descrita em congressos internacionais de Cirurgia Plástica, e a presença de análise estatística foi um determinante para o sucesso de conversão.

Galileo's early inquiries on motion and free fall in Pisa (1588-1592) can be regarded as a case study of multiple knowledge transfer at the very basic roots of modern mechanics. The treatise De motu, unpublished until 1890, is an original but unsuccessful attempt to go beyond Aristotelian physics by extending Archimedean hydrostatics to the dynamics of natural motion and reappraising the late-medieval impetus theory to account for violent motion and acceleration. I will discuss in particular why Galileo was forced to abandon his project before moving to Padua and how the manuscripts De motu provided him with a "research agenda" for further theoretical and experimental investigation.

The problems of the direct composition of a biomedical manuscript on a personal computer are discussed. Most word processing software is unsuitable because literature references, once stored, cannot be rearranged if major changes are necessary. These obstacles have been overcome in Manuscript Manager, a combination of word processing and database software. As it follows Council of Biology Editors and Vancouver rules, the printouts should be technically acceptable to most leading biomedical journals.

In this paper we present a model based on the principles of Linked Data that can be used to describe the interrelationships of images, texts and other resources to facilitate the interoperability of repositories of medieval manuscripts or other culturally important handwritten documents. The model is designed from a set of requirements derived from the real world use cases of some of the largest digitized medieval content holders, and instantiations of the model are intended as the input to collection-independent page turning and scholarly presentation interfaces. A canvas painting paradigm, such as in PDF and SVG, was selected based on the lack of a one to one correlation between image and page, and to fulfill complex requirements such as when the full text of a page is known, but only fragments of the physical object remain. The model is implemented using technologies such as OAI-ORE Aggregations and OAC Annotations, as the fundamental building blocks of emerging Linked Digital Libraries. The model and implementation are evaluated through prototypes of both content providing and consuming applications. Although the system was designed from requirements drawn from the medieval manuscript domain, it is applicable to any layout-oriented presentation of images of text.
The role of food in the functional gastrointestinal disorders: introduction to a manuscript series.
Chey, William D
2013-05-01
Functional gastrointestinal disorders (FGIDs) are characterized by the presence of chronic or recurrent symptoms that are felt to originate from the gastrointestinal (GI) tract, which cannot be attributed to an identifiable structural or biochemical cause. Food is associated with symptom onset or exacerbation in a significant proportion of FGID patients. Despite this, the role of food in the pathogenesis of the FGIDs has remained poorly understood. For this reason, diet has largely played an adjunctive rather than a primary role in the management of FGID patients. In recent years, there has been a rapid expansion in our understanding of the role of food in GI function and sensation and how food relates to GI symptoms in FGID patients. In a series of evidence-based manuscripts produced by the Rome Foundation Working Group on the role of food in FGIDs, comprehensive reviews of the physiological changes associated with nutrient intake, and the respective roles of carbohydrates, fiber, protein, and fats are provided. The series concludes with a manuscript that provides guidance on proper clinical trial design when considering the role of food in FGIDs.

In order to classify the Otani Collection's Dunhuang and Turfan manuscripts, their trace elements were analyzed by PIXE. The paper samples of these manuscripts were fallen off when they were photographed for a CD-ROM catalog. These samples were very small and their size was less than several millimeters. In addition, some paper fragments dating from the late Edo-era of Japan and the late Qing Dynasty of China, and modern Japanese handmade paper were analyzed using PIXE and NAA. Quite interesting results were obtained when analyzing the trace elements - Na, Mg, Al, Si, S, Cl, K, Ca, Sc, Mn, Fe, Cu, Zn, As, Br, Sr, Ba, Pb, La, Sm. It was found that Dunhuang and Turfan papers of the Otani Collection were characterized by its highest iron and bromine content. The reason of the highest iron content probably originates in their making process and/or depends on their preservative environment. On the other hand, it became clear as for the highest bromine content that the origin is from fumigation of methyl bromide. (author)

Plagiarism is common and threatens the integrity of the scientific literature. However, its detection is time consuming and difficult, presenting challenges to editors and publishers who are entrusted with ensuring the integrity of published literature. In this study, the extent of plagiarism in manuscripts submitted to a major specialty medical journal was documented. We manually curated submitted manuscripts and deemed an article contained plagiarism if one sentence had 80 % of the words copied from another published paper. Commercial plagiarism detection software was utilized and its use was optimized. In 400 consecutively submitted manuscripts, 17 % of submissions contained unacceptable levels of plagiarized material with 82 % of plagiarized manuscripts submitted from countries where English was not an official language. Using the most commonly employed commercial plagiarism detection software, sensitivity and specificity were studied with regard to the generated plagiarism score. The cutoff score maximizing both sensitivity and specificity was 15 % (sensitivity 84.8 % and specificity 80.5 %). Plagiarism was a common occurrence among manuscripts submitted for publication to a major American specialty medical journal and most manuscripts with plagiarized material were submitted from countries in which English was not an official language. The use of commercial plagiarism detection software can be optimized by selecting a cutoff score that reflects desired sensitivity and specificity.

It is given the definition of the grammatical norm, summarized the point of view of well-known scientists who study the evolution of the norms of book-Slavic language at different stages of its development and in the establishment and description of the main characteristics of the «strict» and reduced norm of the Church Slavonic language. It is use/disuse of a complicated system of past tenses of verbs, the dual number, principles in the use of participle forms, formation of imperative, causal, conditional and temporary relations and other features. An analysis of the graphic-orthographic and grammatical features of the manuscript concluded that the language of the monument is in the center of the Church Slavonic language of the reduced standard of the XVII century with the appearance of dialectal features inherent to the southern Russian dialects.

A poorly chosen article title may make a paper difficult to discover or discourage readership when discovered, reducing an article's impact. Yet, it is unclear how the structure of a manuscript's title influences readership and impact. We used manuscript tracking data for all manuscripts submitted to the journal Functional Ecology from 2004 to 2013 and citation data for papers published in this journal from 1987 to 2011 to examine how title features changed and whether a manuscript's title structure was predictive of success during the manuscript review process and/or impact (citation) after publication. Titles of manuscripts submitted to Functional Ecology became marginally longer (after controlling for other variables), broader in focus (less frequent inclusion of genus and species names), and included more humor and subtitles over the period of the study. Papers with subtitles were less likely to be rejected by editors both pre- and post-peer review, although both effects were small and the presence of subtitles in published papers was not predictive of citations. Papers with specific names of study organisms in their titles fared poorly during editorial (but not peer) review and, if published, were less well cited than papers whose titles did not include specific names. Papers with intermediate length titles were more successful during editorial review, although the effect was small and title word count was not predictive of citations. No features of titles were predictive of reviewer willingness to review papers or the length of time a paper was in peer review. We conclude that titles have changed in structure over time, but features of title structure have only small or no relationship with success during editorial review and post-publication impact. The title feature that was most predictive of manuscript success: papers whose titles emphasize broader conceptual or comparative issues fare better both pre- and post-publication than do papers with organism

Near-infrared (NIR) or sometimes called black light is a waveform beyond visible light and it is not detectable by human eyes. However electronic sensors such as the type used in digital cameras are able to detect signals in the infrared band. To avoid distortion in the pictures obtained near-infrared is blocked by optical filters inserted in digital cameras. By carrying out minor modification allowing near-infrared signal to be imaged while blocking the visible signal, the camera is turned into a low-cost NIR imaging instrument. NIR imaging can be a useful tool in historical manuscript study or restoration. A few applications have been successfully demonstrated in laboratory experiment using the instrument available in MINT. However, due to unavailability of historical items, easily available texts and paintings are used in the demonstrations. This paper reports achievements of early work on the application of digital camera in the detection of damaged prints or writings. (Author)
Application of image processing technology to problems in manuscript encapsulation. [Codex Hammer
Glackin, D. L.; Korsmo, E. P.
1983-01-01
The long term effects of encapsulation individual sheets of the Codex Hammer were investigated. The manuscript was simulated with similar sheets of paper which were photographed under repeatable raking light conditions to enhance their surface texture, encapsulated in plexiglas, cycled in an environmental test chamber, and rephotographed at selected intervals. The film images were digitized, contrast enhanced, geometrically registered, and apodized. An FFT analysis of a control sheet and two experimental sheets indicates no micro-burnishing, but reveals that the ""mesoscale'' deformations with sizes 8mm are degrading monotonically, which is of no concern. Difference image analysis indicates that the sheets were increasingly stressed with time and that the plexiglas did not provide a sufficient environmental barrier under the simulation conditions. The relationship of these results to the Codex itself is to be determined.

Young researchers may experience difficulties when writing scientific articles for publication in biomedical journals. Various methods may facilitate the writing process including outlining the paper before the actual writing and using dictation instead of writing the first draft. The aim of this study was to investigate the experiences and difficulties for young, experienced researchers when writing articles using a detailed outline and dictation of the first draft. We used qualitative focus group interviews and the study was reported according to the COnsolidated criteria for REporting Qualitative research guideline. Participants were sampled from a group of researchers participating in a writing retreat/course. The interviews were recorded on a digital recorder and transcribed. The text was analyzed according to content analysis and coded and condensed into themes and subthemes. Groups of participants were added until data saturation was reached. A total of 14 researchers participated (9 women and 5 men). Their clinical experience was median (range) of 6 (1-11) years since graduation from medical school. Two themes arose during the analyses of the data: "Process guidance with the outline as the map" and "arrival at dictation." The outline was used in the preparation phase leading up to the day of dictation and was used in collaboration with co-authors and supervisors. The participants found it to be a useful tool for preparing the manuscript and dictating their initial first full draft. Experienced young researchers found beneficial effects of using a structured outline to prepare for dictation of scientific articles. The outline was a tool that would develop in close collaboration with co-authors and mentors. With dictation, a full first draft of a manuscript can be produced in a few hours. Participants positively evaluated this structured and reproducible way of producing scientific articles.

The sequencing of whole genomes and the analysis of genetic information continues to fundamentally change biological and medical research. Unfortunately, the people best suited to interpret this data (biologically trained researchers) are commonly discouraged by their own perceived computational limitations. To address this, we developed a course to help alleviate this constraint. Remarkably, in addition to equipping our undergraduates with an informatic toolset, we found our course design helped prepare our students for collaborative research careers in unexpected ways. Instead of simply offering a traditional lecture- or laboratory-based course, we chose a guided inquiry method, where an instructor-selected research question is examined by students in a collaborative analysis with students contributing to experimental design, data collection, and manuscript reporting. While students learn the skills needed to conduct bioinformatic research throughout all sections of the course, importantly, students also gain experience in working as a team and develop important communication skills through working with their partner and the class as a whole, and by contributing to an original research article. Remarkably, in its first three semesters, this novel computational genetics course has generated 45 undergraduate authorships across three peer-reviewed articles. More importantly, the students that took this course acquired a positive research experience, newfound informatics technical proficiency, unprecedented familiarity with manuscript preparation, and an earned sense of achievement. Although this course deals with analyses of genetic systems, we suggest the basic concept of integrating actual research projects into a 16-week undergraduate course could be applied to numerous other research-active academic fields. © 2015 The International Union of Biochemistry and Molecular Biology.
For the study of the manuscript biblical tradition: a new proposal for the analysis of codex 2437

Full Text Available This article submitted to Horizonte Journal proposes a new way to study the codex 2437, a manuscript written in Greek between the centuries XII and XIII that brings the four Gospels of the canonical New Testament. The interest in this document is growing and it can be justified because it is part of the collection of the National Library of Rio de Janeiro, being considered the oldest manuscript in Latin America. The manuscript is, therefore, a cultural and material heritage that we need to preserve and study more. Our suggestion for the research aims to complement the traditional studies of textual criticism with a methodological framework that was extracted from the History of Writing Culture and contemporary literary studies, fields of knowledge that encourage us to take books not to deal only with its contents, but also to consider some aspects of materiality, paratexts and the history of their uses and readings.

Italian medieval and Renaissance manuscript cuttings and miniatures from the Victoria and Albert Museum were analyzed by Raman microscopy to compile a database of pigments used in different periods and different Italian regions. The palette identified in most manuscripts and cuttings was found to include lead white, gypsum, azurite, lazurite, indigo, malachite, vermilion, red lead, lead tin yellow (I), goethite, carbon, and iron gall ink. A few of the miniatures, such as the historiated capital "M" painted by Gerolamo da Cremona and the Petrarca manuscript by Bartolomeo Sanvito, are of exceptional quality and were analyzed extensively; some contained unusual materials. The widespread usage of iron oxides such as goethite and hematite as minor components of mixtures with azurite is particularly notable. The use of a needle-shaped form of iron gall ink as a pigment rather than a writing material was established by both Raman microscopy and x-ray fluorescence spectroscopy for the Madonna and Child by Franco de' Russi.

There is increasing need for peer reviewers as the scientific literature grows. Formal education in biostatistics and research methodology during residency training is lacking. In this pilot study, we addressed these issues by evaluating a novel method of teaching residents about biostatistics and research methodology using peer review of standardized manuscripts. We hypothesized that mentored peer review would improve resident knowledge and perception of these concepts more than non-mentored peer review, while improving review quality. A partially blinded, randomized, controlled multi-center study was performed. Seventy-eight neurology residents from nine US neurology programs were randomized to receive mentoring from a local faculty member or not. Within a year, residents reviewed a baseline manuscript and four subsequent manuscripts, all with introduced errors designed to teach fundamental review concepts. In the mentored group, mentors discussed completed reviews with residents. Primary outcome measure was change in knowledge score between pre- and post-tests, measuring epidemiology and biostatistics knowledge. Secondary outcome measures included level of confidence in the use and interpretation of statistical concepts before and after intervention, and RQI score for baseline and final manuscripts. Sixty-four residents (82%) completed initial review with gradual decline in completion on subsequent reviews. Change in primary outcome, the difference between pre- and post-test knowledge scores, did not differ between mentored (-8.5%) and non-mentored (-13.9%) residents ( p = 0.48). Significant differences in secondary outcomes (using 5-point Likert scale, 5 = strongly agree) included mentored residents reporting enhanced understanding of research methodology (3.69 vs 2.61; p = 0.001), understanding of manuscripts (3.73 vs 2.87; p = 0.006), and application of study results to clinical practice (3.65 vs 2.78; p = 0.005) compared to non

Hyperspectral imaging (HSI) is a fast non-invasive imaging technology recently applied in the field of art conservation. With the help of chemometrics, important information about the spectral properties and spatial distribution of pigments can be extracted from HSI data. With the intent of expanding the applications of chemometrics to the interpretation of hyperspectral images of historical documents, and, at the same time, to study the colorants and their spatial distribution on ancient illuminated manuscripts, an explorative chemometric approach is here presented. The method makes use of chemometric tools for spectral de-noising (minimum noise fraction (MNF)) and image analysis (multivariate image analysis (MIA) and iterative key set factor analysis (IKSFA)/spectral angle mapper (SAM)) which have given an efficient separation, classification and mapping of colorants from visible-near-infrared (VNIR) hyperspectral images of an ancient illuminated fragment. The identification of colorants was achieved by extracting and interpreting the VNIR spectra as well as by using a portable X-ray fluorescence (XRF) spectrometer.

I (the author), Tadahiko Matsumoto, who is a winner of the 2008 Japanese Society for Medical Mycology (JSMM) Award, was born in 1945 and graduated in 1969 from Kyushu University in Fukuoka, Japan with an M.D. degree. At the Department of Dermatology, Kyushu University I studied dermatology and medical mycology. In Tokyo (1970-1971) at the Department of Microbiology, National Institute of Hygienic Sciences I learned general mycology. During the period from 1981 to 1983 I further studied medical mycology at the Division of Mycotic Diseases (Director: Dr. Libero Ajello), Center for Infectious Diseases, Centers for Disease Control (CDC) in Atlanta, Georgia in the United States. During the period from 1991 to 2005 while working as Director of Dermatology of Toshiba Hospital in Tokyo I was affiliated with several medical schools as a clinical and adjunct professor. Being a unique physician-scientist eager to publish my manuscripts in highly-regarded mycology journals, my studies were accurately reported as to description, taxonomy, and identification. My articles were published in journals carefully chosen for my purposes. As I became better known, I was frequently invited to contribute review articles in leading journals and chapters in authoritative textbooks of dermatology, infectious diseases, and microbiology. I was also invited to be a member and/or chairperson of various symposia in international congresses and one of the lecturers in seminars. I have established many friendly personal relationships among scientists, and we are always ready to help each other whenever necessary.
[On the astrology and computation in the 12th century: new unpublished manuscripts ].
Caiazzo, Irene
2012-01-01
This article examines three so far unknown lemmatic commentaries on computus and on astrolabe topics, which are to be found in MS Stuttgart, Württembergische Landesbibliothek, Cod. math. 4 degrees 33 (second half of the twelfth-century). The commentaries are on the 'Compotus' by Gerlandus, on the 'De mensura astrolabii' by Hermann of Reichenau, and on the 'De utilitatibus astrolabii', which is sometimes attributed to Gerbert of Aurillac. No commentaries on the respective treatises have previously been identified as such. The commentaries of the Stuttgart manuscript are of special interest in that they allow us to understand how a twelfth-century scholar read works on computus and the astrolabe, namely works that date back to the eleventh century. Their author remains anonymous, but in all probability he wrote his commentary on the 'Compotus' by Gerlandus either in 1143 or in 1150. An appendix to the article includes transcriptions of the introductory texts on the computus and on the astrolabe as well as the beginnings of the commentaries.
Distributing Images and Information over the Web - a Case Study of the Pont Manuscript Maps

Full Text Available Technological changes in recent years have encouraged many libraries to deliver digital images of their materials over the Internet. For larger items, including maps, high resolution images of research quality can now be obtained from steadily cheaper equipment, computers can process larger images more comfortably, and newer compression formats have allowed these images to be viewed interactively online. The exponential growth of the Internet has also created a large body of users who wish to access these images from their homes or desktops. Within this context, this paper describes the scanning of the Pont manuscript maps of Scotland, the technology used to make these maps available over the Internet, and the initial stages of the construction of a website of associated information. This case study is not presented as a prescriptive example of best practice, but rather as an illustration of some of the main practical issues involved, using these to present arguments for and against current map digitisation and Web delivery work.

Full Text Available EXTENDED ABSTRACT:The paper gives a thorough examination of the Register of Slovenian-language manuscripts from the 17th and 18th centuries from different points of view: it is presented as a digital repository in humanities disciplines available for searching (digital library and as a methodological framework of further scholarly research and discoveries in the field. Manuscripts, especially the manuscripts of Slovenian literature, have not been sufficiently taken into consideration so far. They have always been given but a sketchy treatment serving merely to illustrate the general outlines of the nation’s literary and cultural development. They have rarely been dealt with in specialised studies or scientific publications. This is the reason why they have not been registered and recorded in archival and library collections. Different guides to manuscripts offer only basic and limited information from which it is often impossible to identify the language, the content, and the history of a manuscript. With regard to the state-of-the- art of Slovenian manuscript research in the field of Slavic studies, archival studies and codicology, it was indispensable to thoroughly record and research the preserved manuscripts by the use of a uniform, rational and consistent method. In reference to these premises a new research project has been started resulting in accurate, thorough and rigorously structured descriptions of manuscripts. The idea of Slovenian manuscript register was developed comprising manuscript descriptions complemented by digital images or facsimiles thus visually presenting the manuscripts and facilitating further research in the field.The 3-year work resulted in the portal: Unknown Slovenian-language manuscripts from the 17th and 18 th centuries. The main project result was the register of Slovenian-language manuscripts from the 17th and 18th centuries. To date, it contains detailed descriptions of the first 100 manuscripts and over 7

Full Text Available The roles of colonial museums in South Asia have been understood in terms of the dissemination of museology within the British Empire. This has often underplayed the participation of local intellectuals in the formation of museum collections, and thus has not recognized their agency in the creation of knowledge and of longstanding cultural assets. This article addresses this in part through an historical case study of the development of the palm-leaf manuscript collection at the Colombo Museum in nineteenth century Ceylon. The article focuses on the relationships between Government aims, local intellectuals and the Buddhist clergy. I argue that colonial museology and collecting activity in Ceylon ought to be understood as a negotiated process and a number of reasons for this are discussed. This article contributes to an area of museological research that is exploring the roles of indigenous actors in colonial collecting and museum practice in South Asia and broader geographical contexts.

By the time it was published in 1705, the Speculum Sapientiae claimed to have had a long history going back to 1672. However, the fact that exaggerated stories were commonplace in alchemical literature leads us to question its credibility. This paper explores the secret lives of this alchemical text prior to its print publication to clarify the roles of manuscripts in early-modern alchemy. Specifically, I argue that there were three aspects that could distinguish manuscript from print: provenance, materiality, and exclusivity. These can be seen at work in the fate of Johann Heinrich Vierordt, an itinerant alchemist and cavalry captain whose career is inextricably linked to the scribal dissemination of the Speculum Sapientiae. In addition to manuscript copies of that text at libraries across Europe, a significant cache of correspondence preserved in Gotha documents Vierordt's dealings with Duke Friedrich I of Saxe-Gotha. The verisimilitudinous provenance of Vierordt's alchemical secrets and tincture played a crucial role in allowing him to gain Friedrich's trust. Yet it was only after Vierordt presented him with a precious parchment manuscript of the Speculum Sapientiae that he truly succeeded in gaining the duke's patronage. Subsequently, reports of multiple conflicting copies surfacing in Amsterdam sealed Vierordt's fall from favour.

The objective of this study was to investigate the incidence of plagiarism in a sample of manuscripts submitted to the AJR using CrossCheck, develop an algorithm to identify significant plagiarism, and formulate management pathways. A sample of 110 of 1610 (6.8%) manuscripts submitted to AJR in 2014 in the categories of Original Research or Review were analyzed using CrossCheck and manual assessment. The overall similarity index (OSI), highest similarity score from a single source, whether duplication was from single or multiple origins, journal section, and presence or absence of referencing the source were recorded. The criteria outlined by the International Committee of Medical Journal Editors were the reference standard for identifying manuscripts containing plagiarism. Statistical analysis was used to develop a screening algorithm to maximize sensitivity and specificity for the detection of plagiarism. Criteria for defining the severity of plagiarism and management pathways based on the severity of the plagiarism were determined. Twelve manuscripts (10.9%) contained plagiarism. Nine had an OSI excluding quotations and references of less than 20%. In seven, the highest similarity score from a single source was less than 10%. The highest similarity score from a single source was the work of the same author or authors in nine. Common sections for duplication were the Materials and Methods, Discussion, and abstract. Referencing the original source was lacking in 11. Plagiarism was undetected at submission in five of these 12 articles; two had been accepted for publication. The most effective screening algorithm was to average the OSI including quotations and references and the highest similarity score from a single source and to submit manuscripts with an average value of more than 12% for further review. The current methods for detecting plagiarism are suboptimal. A new screening algorithm is proposed.

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, ...
The Heritage of Medieval Errors in the Latin Manuscripts of Johannes Hispalensis (John of Seville

Robinson, Maureen
2007-06-01
Full Text Available After the Christian reconquest of Islamic-held territory, many Arabic texts had to be translated into Latin in twelfth century Spain. Johannes Hispalensis (John of Seville knew both Arabic and Latin and worked alone, whereas others needed collaborators to complete the process. The duplication of Latin texts became popular and quickly spread. Over the following centuries, the medieval scribes involved made multiple copies of the manuscripts and during the reproduction process, many errors occurred. These contributed to confusion between the correct version of the translator's name and his identity. Consequently, Hispalensis appeared in later copies of his work with various titles such as “Master” or “Bishop”, or was coupled with a collaborator. Modern-day historians added to the complexities by creating one personality out of two diverse translators. At times, the ownership of some of the manuscripts rested solely on the names appearing in them, when only scribal errors had contributed them. An attempt is made to clarify the translations accredited to Johannes Hispalensis, working alone, and those working with collaborators.

This paper introduces the Bower Manuscript in Sanskrit written on birch bark excavated in Xinjiang, which was bought in Kuqa by a British India army lieutenant Bower, hence its title. Then, it was researched, annotated, and published in 7 volumes by a German British lieutenant and orientalist Honer. The first three volumes are devoted to medical prescriptions. It is first verified that its "Dazi Xiangye San" is the "Dujuan Dachen San" in Tibetan medicine. By comparing it with other traditional medical systems, such as Chinese, Tibetan, Mongolian, and Uyghur medical systems, we found that Bower Manuscript is closer to Tibetan medicine and Mongolian medicine, while it has less relation with Chinese medicine and Uyghur medicine. However, it also exerts some influence on TCM.

Full Text Available Introduction: Explicit teaching of generic conventions of a text genre, usually extracted from native-speaker (NS manuscripts, has long been emphasized in the teaching of Academic Writing inEnglish for Specific Purposes (henceforthESP classes, both in theory and practice. While consciousness-raising about rhetorical structure can be instrumental to non-native speakers(NNS, it has to be admitted that most works done in the field of ESP have tended to focus almost exclusively on native-speaker (NS productions, giving scant attention to non-native speaker (NNS manuscripts. That is, having outlined established norms for good writing on the basis of NS productions, few have been inclined to provide a descriptive account of NNS attempts at trying to produce a research article (RA in English. That is what we have tried to do in the present research. Methods: We randomly selected 20 RAs in dentistry and used two well-established models for results and discussion sections to try to describe the move structure of these articles and show the points of divergence from the established norms. Results: The results pointed to significant divergences that could seriously compromise the quality of an RA. Conclusion: It is believed that the insights gained on the deviations in NNS manuscripts could prove very useful in designing syllabi for ESP classes.

In recent years, several online tools have appeared capable of identifying potential plagiarism in science. While such tools may help to maintain or even increase the originality and ethical quality of the scientific literature, no apparent consensus exists among editors on the degree of plagiarism or self-plagiarism necessary to reject or retract manuscripts. In this study, two entire volumes of published original papers and reviews from Basic & Clinical Pharmacology & Toxicology were retrospectively scanned for similarity in anonymized form using iThenticate software to explore measures to predictively identify true plagiarism and self-plagiarism and to potentially provide guidelines for future screening of incoming manuscripts. Several filters were applied, all of which appeared to lower the noise from irrelevant hits. The main conclusions were that plagiarism software offers a unique opportunity to screen for plagiarism easily but also that it has to be employed with caution as automated or uncritical use is far too unreliable to allow a fair basis for judging the degree of plagiarism in a manuscript. This remains the job of senior editors. Whereas a few cases of self-plagiarism that would not likely have been accepted with today's guidelines were indeed identified, no cases of fraud or serious plagiarism were found. Potential guidelines are discussed. © 2016 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

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.

The American College of Foot and Ankle Surgeons (ACFAS) annual conference has served as a premiere platform to disseminate the latest innovations and research in the field of foot and ankle surgery. The quality of national society conferences is often assessed indirectly by analyzing the the journal publication rate of the abstracts presented. The purpose of this retrospective study was to assess the journal publication rate for abstracts (oral manuscripts and posters) accepted for presentation at the ACFAS conference from 2010 to 2014. All accepted abstracts from this period were compiled by the ACFAS office. PubMed, Google Scholar, and Scopus searches were performed using abstract titles and author names. Overall, the journal publication rate was 76.9% (83 of 108) for oral manuscripts and 23.2% (258 of 1113) for poster abstracts. The mean time to publication was 9.6 (range 0 to 44) months and 19.8 (range 0 to 66) months for oral and poster abstracts, respectively. The most common journal for abstract publication was The Journal of Foot and Ankle Surgery. Notably, the ACFAS oral manuscript publication rate from 2010 to 2014 (76.9%) exceeded its previously reported rate from 1999 to 2008 (67.5%) and the American Orthopaedic Foot and Ankle Society podium publication rate from 2008 to 2012 (73.7%). To the best of our knowledge, the publication incidence for oral abstracts presented at the ACFAS conference is now the highest reported of any national foot and ankle society conference to date.

Full Text Available The purpose of this paper is to analyze a particular linguistic register of the Nahua (Aztec people that has been classified as “magical-religious” because it was used for communication with the sacred realm. A hypothesis is developed that in the Mesoamerican pictographic calendar-religious manuscripts, which treat matters strictly linked to the supernatural world, a similar register should be evident. Far from considering the information presented in these resources as resulting from the direct transcription of oral language, the idea is that the graphic form represents elements emblematic of orality, although adapted to this particular context and mode for expression.
Soma, food of the immortals according to the Bower Manuscript (Kashmir, 6th century A.D.).
Leonti, Marco; Casu, Laura
2014-08-08
Food is medicine and vice versa. In Hindu and Ayurvedic medicine, and among human cultures of the Indian subcontinent in general, the perception of the food-medicine continuum is especially well established. The preparation of the exhilarating, gold-coloured Soma, Amrita or Ambrosia, the elixir and food of the 'immortals'-the Hindu pantheon-by the ancient Indo-Aryans, is described in the Rigveda in poetic hymns. Different theories regarding the botanical identity of Soma circulate, but no pharmacologically and historically convincing theory exists to date. We intend to contribute to the botanical, chemical and pharmacological characterisation of Soma through an analysis of two historical Amrita recipes recorded in the Bower Manuscript. The recipes are referred therein as panaceas (clarified butter) and also as a medicine to treat nervous diseases (oil), while no exhilarating properties are mentioned. Notwithstanding this, we hypothesise, that these recipes are related to the ca. 1800 years older Rigvedic Soma. We suppose that the psychoactive Soma ingredient(s) are among the components, possibly in smaller proportions, of the Amrita recipes preserved in the Bower Manuscript. The Bower Manuscript is a medical treatise recorded in the 6th century A.D. in Sanskrit on birch bark leaves, probably by Buddhist monks, and unearthed towards the end of the 19th century in Chinese Turkestan. We analysed two Amrita recipes from the Bower Manuscript, which was translated by Rudolf Hoernle into English during the early 20th century. A database search with the updated Latin binomials of the herbal ingredients was used to gather quantitative phytochemical and pharmacological information. Together, both Amrita recipes contain around 100 herbal ingredients. Psychoactive alkaloid containing species still important in Ayurvedic, Chinese and Thai medicine and mentioned in the recipe for 'Amrita-Prâsa clarified butter' and 'Amrita Oil' are: Tinospora cordifolia (Amrita, Guduchi), three

The main objective of the work was to establish the internal trends of the author’s ideas’ development in the novel. The tasks were to investigate the problem of studying intertextual relations in the works of Fyodor Dostoyevsky (since the theoretical aspects of the problem were not specifically addressed in previous studies and to analyze the literary material using the textual approach. The source text, which is important for the formation of intertextual relations, is examined not as an individual piece of writing but in the context of the The Raw Youth manuscripts that helps to clarify the nature of its artistic interpretation and the conjunction of folkloristic and biblical concepts in the novel.

Full Text Available The historical evolution of anatomical terms dates to antiquity, to the writings of Hippocrates. The historical development of Lithuanian anatomical terminology goes back to the seventeenth century. Anatomical terminology, as a comprehensive system of the names of human body parts is being compiled gradually. The originator of Lithuanian medical terminology was J. Basanavičius. The research paper aims to analyze anatomical terms used in J. Basanavičius’ manuscript Anatomijos ir medicinos vardyno medžiaga (further BM and to compare them with the terms in the Dictionary of Medical Terms ( Medicinos terminų žodynas 1980. The research focuses on the analysis of some aspects of differentiation and congruity of simple and multi-word anatomical terms of the manuscript and the dictionary. About 270 Lithuanian anatomical terms with Russian and Latin equivalents were collected by J. Basanavičius. The results show that the major part of the terms are different, the lesser part of the terms are identical.

The Miidera-gire is an ancient paper sheet with different, elegant calligraphy on both sides. One side contains a part of a Buddhist scripture from around the ninth to the twelfth century and written in cursive hand, while the other side contains a part of Monzen (an anthology of Chinese literary works). The paleographical style of this Monzen seems to be older than that of the Buddhist scripture and is similar to some Chinese manuscripts written in the Tang Dynasty (AD 618-907). However, amid these elegant calligraphic writings, there exist many copies and counterfeits that were written several centuries later. We, therefore, measured the radiocarbon age of the Miidera-gire by using accelerator mass spectrometry. The calibrated radiocarbon age indicated 666-776 [cal AD] (2{sigma} error), thus leading to the conclusion that the Monzen was first written on the obverse side, and long afterwards, the Buddhist scripture was written on the reverse side. Since only a few incomplete books of Monzen were written before the ninth century, this calligraphy is one of the oldest of the existing Monzen manuscripts. (orig.)

Full Text Available Introduction: Secondary aortoenteric fistula (SAF is an uncommon, but very important complication of abdominal aortic reconstruction. The complication often occurs months to years after aortic surgery. The clinical manifestation of the aortoenteric fistula is always upper gastrointestinal bleeding. Treatment of the disease is early surgical intervention. If operative treatment is not performed promptly, the mortality is high. Case Report: A case of secondary aortoduodenal fistula found 6 years after aortic reconstructive surgery, with the clinical presentation of upper gastrointestinal bleeding because of the increasing number of elective aortic aneurysm repairs in the aging population, it is likely that more patients with SAF will present to the clinical physicians in the future. Hence, a high index of suspicion is necessary for prompt diagnosis and treatment of this lifethreatening event. The patient treated medically and finally expiration of the patient and review of the literature currently available in Medline. Conclusion: The aim of this case report is to emphasize early diagnosis and management of all gastrointestinal bleeding in patients who have a history of aortic reconstructive surgery.

Full Text Available This work reports on the existence of seven manuscripts conserved in three different collections of Aleppo (Syria: the Greek-Catholic/Melkite, the Georges and Mathilde Salem Foundation and the Maronite libraries. These seven copies contain the Arabic translations of some mystical works written by two mystic women of the Spanish Golden Century, Teresa de Ávila and María de Ágreda. The history of these Arabic versions, translated right in the heart of the Ottoman Arabic provinces, constitutes an interesting object of study that is directly linked with the manner in which many European Western works passed to the Mediterranean Levant during the 16th and 17th centuries.

The authors surveyed 21 editors and reviewers from major psychology journals to identify and describe the statistical and design errors they encounter most often and to get their advice regarding prevention of these problems. Content analysis of the text responses revealed themes in 3 major areas: (a) problems with research design and reporting (e.g., lack of an a priori power analysis, lack of congruence between research questions and study design/analysis, failure to adequately describe statistical procedures); (b) inappropriate data analysis (e.g., improper use of analysis of variance, too many statistical tests without adjustments, inadequate strategy for addressing missing data); and (c) misinterpretation of results. If researchers attended to these common methodological and analytic issues, the scientific quality of manuscripts submitted to high-impact psychology journals might be significantly improved.
You can't rely on color, yet we all do 2.0 (Manuscript Only)
van Nes, Floris L.
2014-01-01
Everybody views and uses color from early childhood onwards. But this magnificent property of all objects around us turns out to be elusive if you try to specify it and communicate it to another person. Also, people often don't know what effects color may have under different conditions. However, color is so important and omnipresent, that people can hardly avoid to 'rely on it' - so they do, in particular on its predictability. Thus, there is a discrepancy between the seeming self-evidence of color and the difficulty in specifying it accurately, for the prevailing circumstances. In order to analyze this situation, and possibly remedy it, a short historic perspective of the utilization and specification of color is given. The 'utilization' includes the emotional effects of color, which are important in, for instance, interior decorating but also play a role in literature and religion. 'Specification' begins with the early efforts by scientists, philosophers and artists to bring some order and understanding in what was observed with and while using color. Color has a number of basic functions: embellishment; attracting attention; coding; and bringing order in text by causing text parts presented in the same color to be judged as belonging together. People with a profession that involves color choices for many others, such as designers and manufacturers of products, including electronic visual displays, should have a fairly thorough knowledge of colorimetry and color perception. Unfortunately, they often don't, simply because for 'practitioners' whose work involves different aspects, applying color being only one of those, the available tools for specifying and applying color turn out to be too difficult to use. Two consequences of an insufficient knowledge of the effects color may have are given here. The first of these consequences, on color blindness, relates to 8% of the population, but the second one, on reading colored text, bears on everyone. Practical

We present trace-element and composition analysis of azurite pigments in six illuminated manuscript leaves, dating from the thirteenth to sixteenth century, using synchrotron-based, large-area x-ray fluorescence (SR-XRF) and diffraction (SR-XRD) mapping. SR-XRF mapping reveals several trace elements correlated with azurite, including arsenic, zirconium, antimony, barium, and bismuth, that appear in multiple manuscripts but were not always detected by point XRF. Within some manuscript leaves, variations in the concentration of trace elements associated with azurite coincide with distinct regions of the illuminations, suggesting systematic differences in azurite preparation or purification. Variations of the trace element concentrations in azurite are greater among different manuscript leaves than the variations within each individual leaf, suggesting the possibility that such impurities reflect distinct mineralogical/geologic sources. SR-XRD maps collected simultaneously with the SR-XRF maps confirm the identification of azurite regions and are consistent with impurities found in natural mineral sources of azurite. In general, our results suggest the feasibility of using azurite trace element analysis for provenance studies of illuminated manuscript fragments, and demonstrate the value of XRF mapping in non-destructive determination of trace element concentrations within a single pigment.

The collection generally known as Qumran scrolls or Dead Sea Scrolls (DSS) comprises some 900 highly fragmented manuscripts (mainly written on parchment) from the Second Temple period. In the years since their manufacture the writing materials have undergone serious deterioration due to a combination of natural ageing and environmental effects. Therefore, understanding quantitatively state of conservation of such manuscripts is a challenging task and a deep knowledge of damage pathways on all hierarchical levels (from molecular up to macroscopic) results of fundamental importance for a correct protection and conservation strategy. However, the degradation of parchments is very complex and not well understood process. Parchment is a final product of processing of animal skin and consist mainly of type I collagen, which is the most abundant constituent of the dermal matrix. Collagen molecule is built by folding of three polypeptide α-chains into a right-handed triple helix. Every α-chain is made by a repetitive sequence of (Gly-X-Y)n, where X and Y are often proline and hydroxyproline. Parallel and staggered collagen triple helices associate into fibrils, which than assemble into fibers. Deterioration of parchment is caused by chemical changes due to gelatinization, oxidation and hydrolysis of the collagen chains, promoted by several factors, summarized as biological and microbiological (bacteria, fungi etc.), heat, light, humidity and pollutants (1, 2). In this work we have focused on studying the collagen within parchments on two different levels of organization (molecular and fibrilar) by applying polarized Raman spectroscopic technique. Beside spectral information related to chemical bonding, polarization anisotropy of some collagen bands (i.e. amide I) has been used to explore organization of collagen on higher levels (three-dimensional arrangement of the triple-helix molecules and their alignment within a fibril of collagen). To this aim we have compared

Culture in Catalonia and, specifically, science had an important rebirth in the second half of the 19th century. But, due to the lack of State support, development of earth physical sciences in Catalonia at the beginning of the 20th century was almost a private enterprise. This situation caused dispersion of the efforts that, in any case, were extensive. The study of the evolution of earth sciences and the recovery and study of the accumulated data in such circumstances requires relying heavily on manuscript information. The present study deals with the problems and possibilities of this situation, shows some study cases and extracts some conclusions of general interest from them.

The primary functions of peer reviewers are poorly defined. Thus far no body of literature has systematically identified the roles and tasks of peer reviewers of biomedical journals. A clear establishment of these can lead to improvements in the peer review process. The purpose of this scoping review is to determine what is known on the roles and tasks of peer reviewers. We will use the methodological framework first proposed by Arksey and O'Malley and subsequently adapted by Levac et al and the Joanna Briggs Institute. The scoping review will include all study designs, as well as editorials, commentaries and grey literature. The following eight electronic databases will be searched (from inception to May 2017): Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, Educational Resources Information Center, EMBASE, MEDLINE, PsycINFO, Scopus and Web of Science. Two reviewers will use inclusion and exclusion criteria based on the 'Population-Concept-Context' framework to independently screen titles and abstracts of articles considered for inclusion. Full-text screening of relevant eligible articles will also be carried out by two reviewers. The search strategy for grey literature will include searching in websites of existing networks, biomedical journal publishers and organisations that offer resources for peer reviewers. In addition we will review journal guidelines to peer reviewers on how to perform the manuscript review. Journals will be selected using the 2016 journal impact factor. We will identify and assess the top five, middle five and lowest-ranking five journals across all medical specialties. This scoping review will undertake a secondary analysis of data already collected and does not require ethical approval. The results will be disseminated through journals and conferences targeting stakeholders involved in peer review in biomedical research. © Article author(s) (or their employer(s) unless otherwise stated in the text of the

Multiple authorship is the universal solution to multi-tasking in the sciences. Without a team, each with their own set of expertise, and each involved mostly in complementary ways, a research project will likely not advance quickly, or effectively. Consequently, there is a risk that research goals will not be met within a desired timeframe. Research teams that strictly scrutinize their modus operandi select and include a set of authors that have participated substantially in the physical undertaking of the research, in its planning, or who have contributed intellectually to the ideas or the development of the manuscript. Authorship is not an issue that is taken lightly, and save for dishonest authors, it is an issue that is decided collectively by the authors, usually in sync with codes of conduct established by their research institutes or national ministries of education. Science, technology and medicine (STM) publishers have, through independent, or sometimes coordinated efforts, also established their own sets of guidelines regarding what constitutes valid authorship. However, these are, for the greater part, merely guidelines. A previous and recent analysis of authorship definitions indicates that the definitions in place regarding authorship and its validity by many leading STM publishers is neither uniform, nor standard, despite several of them claiming to follow the guidelines as set forward by the International Committee of Medical Journal Editors or ICMJE. This disparity extends itself to ghost and guest authorship, two key authorship-related issues that are examined in this paper to assess the extent of discrepancies among the same set of STM publishers and what possible influence they might have on publishing ethics.

The super Patalan numbers generalize the super Catalan numbers similarly to how the Patalan numbers generalize the Catalan numbers.

Despite a dramatic influx of female dermatologists during the last 30 years, women in academic dermatology departments remain relatively clustered in junior faculty positions. Research in other specialties showing a disparity in the academic productivity of women has led to many hypotheses regarding factors that may place them at a competitive disadvantage. It is unknown, however, whether similar differences in academic productivity might also serve as barriers to advancement in dermatology, or whether any productivity gap actually exists in this specialty that experienced a more substantial entry of women. Because publication in peer-reviewed journals is one of the core measures of academic productivity used in the promotion process, we evaluated trends in the prevalence of female authorship in top dermatology journals during the last 3 decades. We conducted an observational study of trends in the sex distribution of US authors in 3 prestigious general dermatology journals (in 1976, 1986, 1996, and 2006) and 3 subspecialty dermatology journals (in 2006 only). Journals were chosen based on published impact factors and citation half-lives. During the last 3 decades, the proportion of women authoring manuscripts in the 3 major general dermatology journals increased from 12% to 48% of US-affiliated first authors (P < .001) and from 6.2% to 31% of US-affiliated senior authors (P < .001). Separate analyses by journal and by article type showed similar increases. The prevalence of female authors in subspecialty journals in 2006 was slightly more variable. Although the publications selected for this study capture many of the most respected US journals in dermatology, they may not be representative of all journals in which dermatologists publish. Female dermatologists are authoring publications in growing numbers that match or exceed their prevalence in the academic and overall workforce. This suggests that other factors (differences in productivity outside of the

Its main objective was the implementation of the state program for the “village reconstruction” (Vladimir Lenin in the spirit of “raskrestyanivanie” [de-peasant-ring]. IWL archives (fund 156 contain rich materials on the history of the two periods of VOKP’s activity, its agendas as well as evidence of its creative and ideological work with aspiring village writers. In the first period, 1921–1927, the Society rendered real help to peasants, primarily in literary studies, within the framework of the so called struggle against the peasantry ignorance. After 1927, albeit VOKP was extended, the activity of the Society concentrated on the crusade against the kulak and petty-bourgeois ideology. While the All-Russian Peasants’ Union of Writers was being transformed into the Russian Society of Proletarian and Kolkhoz Writers, the Society tried to decide who was a “true” or “genuine” peasant writer and who therefore had the right to instruct beginners. The work of «kulak poets» such as S. A. Yesenin and N. A. Klyuyev was no longer considered appropriate for the poetical education of younger people. Drawing on the reviews of the poetical works from the VOKP fund, the essay seeks to understand how the Society evaluated ideology and aesthetics of these works, what kind of advice and recommendations it gave to the authors and eventually what were the criteria for publication and for the VOKP membership. The article argues that conformity to the so called Proletarian and Kolkhoz ideology was becoming into the defining principle of evaluation and

The decision-making process includes a series of activities undertaken in biomedical journals from the moment a manuscript is received until it is accepted or rejected. Firstly, the manuscript is evaluated by the members of the Editorial Board, who analyze both its suitability for the journal and its scientific quality. After this initial evaluation, the article is evaluated by peer reviewers, an essential process to guarantee its scientific validity. Both the Editorial Board and the peer reviewers usually use checklists which are of enormous help in this task. Once the biomedical article has been accepted, the publication process is started, which in turn includes a series of steps, beginning with technical and medical review of the article's contents and ending with the article's publication in the journal. The present article provides a detailed description of the main technical and ethical issues involved in the processes of decision-making and publication of biomedical articles.

In an effort to identify previously unrecognized aspects of editorial decision-making, we explored the words and phrases that one group of editors used during their meetings. We performed an observational study of discussions at manuscript meetings at JAMA, a major US general medical journal. One of us (KD) attended 12 editorial meetings in 2003 as a visitor and took notes recording phrases from discussion surrounding 102 manuscripts. In addition, editors attending the meetings completed a form for each manuscript considered, listing the reasons they were inclined to proceed to the next step in publication and reasons they were not (DR attended 4/12 meetings). We entered the spoken and written phrases into NVivo 2.0. We then developed a schema for classifying the editors' phrases, using an iterative approach. Our classification schema has three main themes: science, journalism, and writing. We considered 2,463 phrases, of which 87 related mainly to the manuscript topic and were not classified (total 2,376 classified). Phrases related to science predominated (1,274 or 54%). The editors, most of whom were physicians, also placed major weight on goals important to JAMA's mission (journalism goals) such as importance to medicine, strategic emphasis for the journal, interest to the readership, and results (729 or 31% of phrases). About 16% (n = 373) of the phrases used related to writing issues, such as clarity and responses to the referees' comments. Classification of editorial discourse provides insight into editorial decision making and concepts that need exploration in future studies.

Foundations of analysis over surreal number fields
Alling, NL
1987-01-01
In this volume, a tower of surreal number fields is defined, each being a real-closed field having a canonical formal power series structure and many other higher order properties. Formal versions of such theorems as the Implicit Function Theorem hold over such fields. The Main Theorem states that every formal power series in a finite number of variables over a surreal field has a positive radius of hyper-convergence within which it may be evaluated. Analytic functions of several surreal and surcomplex variables can then be defined and studied. Some first results in the one variable case are derived. A primer on Conway''s field of surreal numbers is also given. Throughout the manuscript, great efforts have been made to make the volume fairly self-contained. Much exposition is given. Many references are cited. While experts may want to turn quickly to new results, students should be able to find the explanation of many elementary points of interest. On the other hand, many new results are given, and much mathe...

Full Text Available The paper offers new arguments for the more exact dating – autumn-winter of 963 – of the manuscript of the treatise De cerimoniis aulae byzantinae (Leipzig, Univ. Bibl. Rep. I 17. At the end of the list of the tombs of the emperors in the Mausoleum of Constantine the Great in the Church of the Holy Apostles, included in this compilation treatise, the scribe missed three empty lines. The last emperor in the list of buried emperors is Constantine VII Porphyrogenitus; there is no sarcophagus of his son Roman II, known from the later lists of tombs. The list ends with a mention of the “small sarcophagus” (τὸ λαρνάκιον; and there is no indication, whether there was someone buried there. Judging by the chronicles of Yahya of Antioch and Leo Deacon, as well as The Brief History by Michael Psellos, since the death of Emperor Roman II there was a constant danger of the liquidation of his children – Basil, Constantine and Anna. Apparently, this small coffin was prepared for them, and the scribe of the codex left a place to finish the final distribution of the last representatives of the imperial house in the mausoleum. However, all the children saved their lives, and three blank lines in the manuscript were never filled. Consequently, the manuscript was already completed after August 16, 963, and it is unlikely that the work on it was completed much later than the autumn-winter of 963.

Full Text Available Electrical impedance tomography (EIT is used to monitor the regional distribution of ventilation in a transversal plane of the thorax. In this manuscript we evaluate the impact of different quantities of electrodes used for current injection and voltage measurement on the reconstructed shape of the lungs. Results indicate that the shape of reconstructed impedance changes in the body depends on the number of electrodes. In this manuscript, we demonstrate that a higher number of electrodes do not necessarily increase the image quality. For the used stimulation pattern, utilizing neighboring electrodes for current injection and voltage measurement, we conclude that the shape of the lungs is best reconstructed if 16 electrodes are used.

During his stay in Bessarabia, Wiegel wrote his famous essay “Observations on the present state of affairs in Bessarabia” (1823, which was nothing more than a pamphlet, a sarcastic satire on the Bessarabian society containing allusions to many representatives of local authorities who for various reasons were unpleasant to the author. Moreover, the notes are full of slander and contempt towards the natives. Apparently, Wigel intended to keep his pamphlet in secret, but could not resist distributing several copies among friends – a mistake that brought him a lot of misery later on in life. Wieghel’s memoirs are vast and can serve as a source of information for those wishing to know the atmosphere that prevailed at the beginning of the 19th century in the newly annexed province of the Russian Empire. Our study aims to determine the bibliophilic value of the manuscript relative to other valuable books stored in the Central Scientific Library of the Academy of Sciences of Moldova.

This article is an analysis of Derek Morgan's manuscript-'Coming Back to Life: The Normal Chaos of Medical Law', which remained unpublished at his death in 2011. Morgan made two claims in the manuscript: (1) medical practitioners and patients approach health from the different perspectives of 'reason' and 'emotion' respectively, while medical law treads the line between these ultimately resulting in 'normal chaos'. (2) In this respect, medical law ought to be coaxed 'back to life' so that it can address broader principles and values in respect to practical resolution; however, it has, in the face of this chaos, become dull in its ambitions. In this article, I first analyse these two claims in detail, before, second, illustrating the 'normal chaos' of medical law using the debate over ownership of human cells and tissues. I draw my own conclusions as to whether Morgan's final thesis was successful. © The Author [2014]. Published by Oxford University Press; all rights reserved.

Full Text Available The National Library of Norway is planning to digitise approximately 1,500 manuscript maps. Two years ago we started working on a pilot project, and for this purpose we chose 22 maps small enough to be photographed in one piece. We made slides 6 x 7 cm in size, converted the slides into PhotoCDs and used four different resolutions on JPEG-files. To avoid large file sizes, we had to divide the version with the biggest resolution into four pieces. The preliminary work was done in Photoshop, the database on the web is made in Oracle. You can click on the map to zoom. Norwegians and probably Swedes during the Great Northern War drew the 22 maps when the Swedish King Charles XII in 1716 and 1718 unsuccessfully attempted to conquer Norway. The database is now accessible on the National Library of Norway's web site. The database is in Norwegian, but we are working on an English version as well. The maps are searchable on different topics, countries, counties, geographical names, shelfmarks or a combination of these. We are planning to expand the database to other manuscript maps later. This is the reason why it is possible to search for obvious subjects as Charles XII and the Great Northern War.

Full Text Available The Talmud manuscripts Magl. coll. II.I.8 and 9 of the Biblioteca Nazionale Centrale of Florence contain marginal Talmud-translations in Latin which correspond to the 13th century translation Extractiones de Talmud. The two manuscripts are described and their textual evidence is compared both with the Latin manuscript tradition of the Extractiones and with the Hebrew/Aramaic Talmudic text which they contain, trying to answer the question of whether the Florence manuscripts are the Vorlage of the Latin translation of the Talmud. The matter reveals itself as complex: striking analogies seem to suggest an affirmative answer to the question at stake; however, evidence can also be found which rather supports the opposite conclusion. Nevertheless, the Florence manuscripts certainly belong to a Hebrew/Aramaic tradition which is very close to the Vorlage of the Extractiones. Moreover, the Latin text they offer in their magins reflects a prior stage of work in the production of the Extractiones, featuring unique variants and passages, which are corrected or omitted in the rest of the Latin manuscript tradition.

The set of asymptotic numbers A as a system of generalized numbers including the system of real numbers R, as well as infinitely small (infinitesimals) and infinitely large numbers, is introduced. The detailed algebraic properties of A, which are unusual as compared with the known algebraic structures, are studied. It is proved that the set of asymptotic numbers A cannot be isomorphically embedded as a subspace in any group, ring or field, but some particular subsets of asymptotic numbers are shown to be groups, rings, and fields. The algebraic operation, additive and multiplicative forms, and the algebraic properties are constructed in an appropriate way. It is shown that the asymptotic numbers give rise to a new type of generalized functions quite analogous to the distributions of Schwartz allowing, however, the operation multiplication. A possible application of these functions to quantum theory is discussed

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...

Number theory is the branch of mathematics concerned with the counting numbers, 1, 2, 3, … and their multiples and factors. Of particular importance are odd and even numbers, squares and cubes, and prime numbers. But in spite of their simplicity, you will meet a multitude of topics in this book: magic squares, cryptarithms, finding the day of the week for a given date, constructing regular polygons, pythagorean triples, and many more. In this revised edition, John Watkins and Robin Wilson have updated the text to bring it in line with contemporary developments. They have added new material on Fermat's Last Theorem, the role of computers in number theory, and the use of number theory in cryptography, and have made numerous minor changes in the presentation and layout of the text and the exercises.

Considered an institution mainly devoted to astrology and medicine by Simon de Phares and by some historians who believe that he was reliable, the college founded in 1371 by Charles V's first physician, Gervais Chrétien, was in fact primarily dedicated to theological students. It was not before 1377 that there were created there two bursaries for scholares regis, specialising in 'licit mathematical sciences', and two medical fellowships. Yet the influence of the activity of these fellows seems to have been rather moderate and-as far as we can learn from the material still extant, notably from manuscripts that belonged to Maître Gervais' College and to some of its members-this institution was devoted much more to theological studies than to medicine and the quadrivium.

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

We investigate the ‘law of small numbers’ using a data set on lotto gambling that allows us to measure players’ reactions to draws. While most players pick the same set of numbers week after week, we find that those who do change react on average as predicted by the law of small numbers...... as formalized in recent behavioral theory. In particular, players tend to bet less on numbers that have been drawn in the preceding week, as suggested by the ‘gambler’s fallacy’, and bet more on a number if it was frequently drawn in the recent past, consistent with the ‘hot-hand fallacy’....

"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 ...
Intuitive numbers guide decisions

Full Text Available Measuring reaction times to number comparisons is thought to reveal a processing stage in elementary numerical cognition linked to internal, imprecise representations of number magnitudes. These intuitive representations of the mental number line have been demonstrated across species and human development but have been little explored in decision making. This paper develops and tests hypotheses about the influence of such evolutionarily ancient, intuitive numbers on human decisions. We demonstrate that individuals with more precise mental-number-line representations are higher in numeracy (number skills consistent with previous research with children. Individuals with more precise representations (compared to those with less precise representations also were more likely to choose larger, later amounts over smaller, immediate amounts, particularly with a larger proportional difference between the two monetary outcomes. In addition, they were more likely to choose an option with a larger proportional but smaller absolute difference compared to those with less precise representations. These results are consistent with intuitive number representations underlying: a perceived differences between numbers, b the extent to which proportional differences are weighed in decisions, and, ultimately, c the valuation of decision options. Human decision processes involving numbers important to health and financial matters may be rooted in elementary, biological processes shared with other species.

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

Full Text Available The issue of ismat al-anbiya (preservation of the Prophets from sin is one of the subjects made its presence felt in the history of Islamic thought since the early periods. Shihabuddîn Ahmed b. Muhammed al-Hamawî’s (d. 1098/1687 manuscript called Ithâf al-azkiyâ bi tahqiqi mes’eleti ʻismat al-anbiyâ is one of the detach works in this field. The alleged idea of “some prophets committing sin sometimes” suggested by Muhtâr b. Mahmûd al-Zâhidî (d. 658/1260, one of the scholars of Mutazilî-Hanafî, drew a specific attention because this idea was mentioned in al-Ashbâh ve’n-nazâir, a significant work of Sunni-Hanafi world. The work in your hand presents the critical editon of the work and the examination as to the manuscript of Hamawi in which he discussed the relevant idea. The author assesses the concept of sin related to the subject under the classification of blasphemy, lie, and other sins and looks for a solution of the subject gradually by separating the sins into big or small, on purpose or by mistake, based on gloss or not, disgraceful/injuring the respectability or not, have a legal sanction or not, begun or continued, before or after revelation. In other words, on the way to the solution, a more concrete basis is formed on the practical responses of the mentioned idea.

The subject of random number generation is currently controversial. Differing opinions on this subject seem to stem from implicit or explicit differences in philosophy; in particular, from differing ideas concerning the role of probability in the real world of physical processes, electronic computers, and Monte Carlo calculations. An attempt is made here to reconcile these views. The role of stochastic ideas in mathematical models is discussed. In illustration of these ideas, a mathematical model of the use of random number generators in Monte Carlo calculations is constructed. This model is used to set up criteria for the comparison and evaluation of random number generators. (U.S.)

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.

Full Text Available A powerful number is a positive integer n satisfying the property that p2 divides n whenever the prime p divides n; i.e., in the canonical prime decomposition of n, no prime appears with exponent 1. In [1], S.W. Golomb introduced and studied such numbers. In particular, he asked whether (25,27 is the only pair of consecutive odd powerful numbers. This question was settled in [2] by W.A. Sentance who gave necessary and sufficient conditions for the existence of such pairs. The first result of this paper is to provide a generalization of Sentance's result by giving necessary and sufficient conditions for the existence of pairs of powerful numbers spaced evenly apart. This result leads us naturally to consider integers which are representable as a proper difference of two powerful numbers, i.e. n=p1−p2 where p1 and p2 are powerful numbers with g.c.d. (p1,p2=1. Golomb (op.cit. conjectured that 6 is not a proper difference of two powerful numbers, and that there are infinitely many numbers which cannot be represented as a proper difference of two powerful numbers. The antithesis of this conjecture was proved by W.L. McDaniel [3] who verified that every non-zero integer is in fact a proper difference of two powerful numbers in infinitely many ways. McDaniel's proof is essentially an existence proof. The second result of this paper is a simpler proof of McDaniel's result as well as an effective algorithm (in the proof for explicitly determining infinitely many such representations. However, in both our proof and McDaniel's proof one of the powerful numbers is almost always a perfect square (namely one is always a perfect square when n≢2(mod4. We provide in §2 a proof that all even integers are representable in infinitely many ways as a proper nonsquare difference; i.e., proper difference of two powerful numbers neither of which is a perfect square. This, in conjunction with the odd case in [4], shows that every integer is representable in

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.

Since reflection or transmission of a quantum particle on a beamsplitter is inherently random quantum process, a device built on this principle does not suffer from drawbacks of neither pseudo-random computer generators or classical noise sources. Nevertheless, a number of physical conditions necessary for high quality random numbers generation must be satisfied. Luckily, in quantum optics realization they can be well controlled. We present an easy random number generator based on the division of weak light pulses on a beamsplitter. The randomness of the generated bit stream is supported by passing the data through series of 15 statistical test. The device generates at a rate of 109.7 kbit/s.

Some art objects being small and very precious prevents conservators and conservation scientists from whatever kind of sampling, so that only completely non-invasive (n.i.) studies are permitted. Besides, also moving the object is sometimes forbidden: this happens for jewels as well as for manuscripts, illuminated codices, drawings and paintings. Some important physical n.i. analyses, such as PIXE and PIGE, therefore cannot be used in many cases. With these limitations, only imaging techniques in X, UV, Visible and IR bands, and a few spectroscopic methods that can be carried out with portable instruments can be applied, i.e. molecular spectroscopies like Fourier transform infrared (FTIR), Raman, UV visible and near IR reflectance spectrometry (UV-Vis-NIR RS) and atomic spectroscopy like energy dispersive X-ray fluorescence (EDXRF). The use of only one or two of these techniques is usually far from giving all the information required to achieve a full characterization of materials used by the artist or during restorations, and to understand some conservative problems of the object. On the contrary, a joined use of n.i. analyses can supply a larger set of data, allowing for cross checks. With this aim we show a fully integrated spectroscopic approach to polychrome objects, and, in particular, to drawings and illuminated manuscripts, using portable instruments, specifically μ-FTIR, μ-Raman, Vis-RS and EDXRF, where also the Raman signal does not suffer fluorescence caused by varnish coating and from binder. We propose the joined use of all these four physical analyses to characterize materials - support, pigments, dyes, binders, etc. - on a complex case: a painted and drawn parchment of the late 15th century, or the beginning of the 16th, partly attributed to Andrea Mantegna. The collected spectroscopic data have been compared to proper spectral databases, some of which specifically realized in our laboratories. Also, mixtures of pigments and their stratigraphical

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

Full Text Available Given the widespread use of English for the international dissemination of scholars’ research results, numerous intercultural analyses have been undertaken in the field of English for Academic Purposes in diverse genres. Rhetorical and discursive conventions across languages and cultures have been studied to help non-native English scholars to be successful in the difficult endeavour of being granted publication in international English-medium publications. The increasing competition to get one’s research published in international journals in English has resulted in the authors’ need to clearly spell out what their contribution to their discipline is, a rhetorical convention which seems to be currently crucial especially in some fields. It is the aim of this paper to trace statements of contribution in the Introduction and Conclusion sections of research articles published in two international journals in finance and to compare the results with those obtained from an analysis of three manuscripts written in English by a team of Spanish scholars sent to the same journals but which received major revision or rejection reports. Reference to these statements made by reviewers in their reports will also be analysed to explore to what extent (non compliance with this rhetorical convention may influence their final decision (not to recommend publication.

In this study we sought to validate the discriminant ability of the Evaluation Tool of Children's Handwriting-Manuscript in identifying children in Grades 2-3 with handwriting difficulties and to determine the percentage of change in handwriting scores that is consistently detected by occupational therapists. Thirty-four therapists judged and compared 35 pairs of handwriting samples. Receiver operating characteristic (ROC) analyses were performed to determine (1) the optimal cutoff values for word and letter legibility scores that identify children with handwriting difficulties who should be seen in rehabilitation and (2) the minimal clinically important difference (MCID) in handwriting scores. Cutoff scores of 75.0% for total word legibility and 76.0% for total letter legibility were found to provide excellent levels of accuracy. A difference of 10.0%-12.5% for total word legibility and 6.0%-7.0% for total letter legibility were found as the MCID. Study findings enable therapists to quantitatively support clinical judgment when evaluating handwriting. Copyright © 2012 by the American Occupational Therapy Association, Inc.

The round figure for the current year has stirred people's minds in anticipation. Numbers have acquired great significance also in today's medical science. The Paris physician Pierre Charles Alexandre Louis (1787-1872) is considered the founding father of the numerical method in medicine. At first the principle of aggregating data from different individuals aroused much resistance and even disgust: Claude Bernard was a leading figure among those who warned that one will never find a mean in nature, and that grouping findings together obscures the true relationship between biological phenomena. True enough, statistical significance is not a characteristic of nature itself. Significant differences or risk reductions do not necessarily imply clinical relevance, and results obtained in a group of patients are rarely applicable to an individual patient in the consultation room. Likewise, the health of a human being cannot be captured in biochemical, radiological or other technical measures, nor in disease-specific scales that reduce well-being to one or two digits. The editors of this journal will remain keen on publishing numerical studies that contribute to evidence-based medicine, but at the same time they will continue to foster the art of reporting illness from the point of view of the sick person.
Lepton family number violation
International Nuclear Information System (INIS)
Herczeg, P.
1999-01-01
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 τ, 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 India, since ancient times Tri-phalā (meaning "three fruits" in Sanskrit) has been considered to be a combination of the following fruits: -Harītakī (Terminalia chebula, Retz.), Āmalaka (Embelica officinalis Gaertn), and Vibhītaka (Terminalia belerica Roxb.). These plants are also listed in the Ayurvedic Pharmacopoeia of India. Harītakī and Āmalaka have also been used for medicinal purposes since ancient times in Japan under the Japanese names of (see text) (Kariroku) and (see text) (Annmaroku), respectively. Both have been carefully preserved as treasured drugs in the nationally important Shosoin treasure storehouse. This study attempts to clarify the description of Tri-phalā in the Nāvanītaka, which is the second part of the Bower Manuscript (Bower Ms.), and examines the reasons why these plants were combined. This paper begins with a summary description of Tri-phalā in the context of traditional Asian medicine, followed by the delineation of drug selection principles in Ayurveda. Tri-phalā formulas in the Nāvanītaka are then examined. The Carakasamhitā (CS) treats Tri-phalā as a purifier and tonic (rasāyana), describing it as a formula for rejuvenation and longevity. On the other hand, the Susrutasamhitd (SS) regards Tri-phalā as having the efficacy of balancing kapha (phlegm) and pitta (bile), and also as being a medicine to promote excretion and enhance digestive functions for better nutritional intake. It is described to have an effect of curing diseases by keeping the tridhāu (theree element) valance. Tri-phalā is thus used as an ingredient of laxatives for diseases that result from kapha imbalance and tonic. The Aşţāngahŗdayasamhitā (AHS) considers Tri-phalā to have a particular superiority among cure-all medicines with the power to dispel illness. It controls kapha and overcomes blood diseases. Tri-phalā formulas found in the Nāvanītaka were prescribed for the treatment of abdominal tumors induced by vāyu (wind) disorder

The preservation of manuscripts and archive materials is a serious problem for librarians and restorers. Paper manuscript is subjected to numerous degradation factors affecting their conservation state. This research represents an attempt to evaluate the conservation restoration process applied in Moroccan libraries, especially the alkaline treatment for strengthening weakened paper. In this study, we focused on six samples of degraded and restored paper taken from three different Moroccan manuscripts aged 150, 200 and 800 years. In addition, the Japanese paper used in restoration has been characterized. A modern paper was also analyzed as reference. A three-step analytical methodology based on infrared spectroscopy (ATR-FTIR), X-ray diffraction (XRD) and scanning electron microscopy coupled to energy dispersive spectrometry (SEM-EDS) analysis was developed before and after restoration in order to determine the effect of the consolidation treatment on the paper structure. The results obtained by XRD and ATR-FTIR disclosed the presence of barium sulfate (BaSO4) in all restored paper manuscripts. The presence of calcium carbonate (CaCO3) in all considered samples was confirmed by FTIR spectroscopy. The application of de-acidification treatment causes significant changes connected with the increase of intensity mostly in the region 1426 cm(-1), assigned to the asymmetric and symmetric CO stretching mode of calcite, indicating the effectiveness of de-acidification procedure proved by the rise of the alkaline reserve content allowing the long term preservation of paper. Observations performed by SEM magnify the typical paper morphology and the structure of fibbers, highlighting the effect of the restoration process, manifested by the reduction of impurities.

Analysis of entropy extraction efficiencies in random number generation systems
Wang, Chao; Wang, Shuang; Chen, Wei; Yin, Zhen-Qiang; Han, Zheng-Fu
2016-05-01
Random numbers (RNs) have applications in many areas: lottery games, gambling, computer simulation, and, most importantly, cryptography [N. Gisin et al., Rev. Mod. Phys. 74 (2002) 145]. In cryptography theory, the theoretical security of the system calls for high quality RNs. Therefore, developing methods for producing unpredictable RNs with adequate speed is an attractive topic. Early on, despite the lack of theoretical support, pseudo RNs generated by algorithmic methods performed well and satisfied reasonable statistical requirements. However, as implemented, those pseudorandom sequences were completely determined by mathematical formulas and initial seeds, which cannot introduce extra entropy or information. In these cases, “random” bits are generated that are not at all random. Physical random number generators (RNGs), which, in contrast to algorithmic methods, are based on unpredictable physical random phenomena, have attracted considerable research interest. However, the way that we extract random bits from those physical entropy sources has a large influence on the efficiency and performance of the system. In this manuscript, we will review and discuss several randomness extraction schemes that are based on radiation or photon arrival times. We analyze the robustness, post-processing requirements and, in particular, the extraction efficiency of those methods to aid in the construction of efficient, compact and robust physical RNG systems.
[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.

Our fascination with numbers begins when we are children and continues throughout our lives. We start counting our fingers and toes and end up balancing checkbooks and calculating risk. So powerful is the appeal of numbers that many people ascribe to them a mystical significance. Other numbers go beyond the supernatural, working to explain our universe and how it behaves. In Cosmic Numbers , mathematics professor James D. Stein traces the discovery, evolution, and interrelationships of the numbers that define our world.

The two known methods for introducing a conserved fermion number into supersymmetric models are discussed. While the introduction of a conserved fermion number often requires that the Lagrangian be massless or that bosons carry fermion number, a model is discussed in which masses can be introduced via spontaneous symmetry breaking and fermion number is conserved at all stages without assigning fermion number to bosons.

Ejersbo, Lisser Rye; Misfeldt, Morten
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 th......, a second, regular set of number names is introduced in primary school. The study’s findings suggest that the regularity of number names influences the development of number concepts and creates a positive impact on the understanding of the base-10 system....

Generalized Bernoulli-Hurwitz numbers and the universal Bernoulli numbers
International Nuclear Information System (INIS)
Ônishi, Yoshihiro
2011-01-01
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.

Photon number projection using non-number-resolving detectors

2007-01-01
Number-resolving photo-detection is necessary for many quantum optics experiments, especially in the application of entangled state preparation. Several schemes have been proposed for approximating number-resolving photo-detection using non-number-resolving detectors. Such techniques include multi-port detection and time-division multiplexing. We provide a detailed analysis and comparison of different number-resolving detection schemes, with a view to creating a useful reference for experimentalists. We show that the ideal architecture for projective measurements is a function of the detector's dark count and efficiency parameters. We also describe a process for selecting an appropriate topology given actual experimental component parameters
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.
Dynamic Virtual Credit Card Numbers
Molloy, Ian; Li, Jiangtao; Li, Ninghui
Theft of stored credit card information is an increasing threat to e-commerce. We propose a dynamic virtual credit card number scheme that reduces the damage caused by stolen credit card numbers. A user can use an existing credit card account to generate multiple virtual credit card numbers that are either usable for a single transaction or are tied with a particular merchant. We call the scheme dynamic because the virtual credit card numbers can be generated without online contact with the credit card issuers. These numbers can be processed without changing any of the infrastructure currently in place; the only changes will be at the end points, namely, the card users and the card issuers. We analyze the security requirements for dynamic virtual credit card numbers, discuss the design space, propose a scheme using HMAC, and prove its security under the assumption the underlying function is a PRF.
Number-unconstrained quantum sensing
Mitchell, Morgan W.
2017-12-01
Quantum sensing is commonly described as a constrained optimization problem: maximize the information gained about an unknown quantity using a limited number of particles. Important sensors including gravitational wave interferometers and some atomic sensors do not appear to fit this description, because there is no external constraint on particle number. Here, we develop the theory of particle-number-unconstrained quantum sensing, and describe how optimal particle numbers emerge from the competition of particle-environment and particle-particle interactions. We apply the theory to optical probing of an atomic medium modeled as a resonant, saturable absorber, and observe the emergence of well-defined finite optima without external constraints. The results contradict some expectations from number-constrained quantum sensing and show that probing with squeezed beams can give a large sensitivity advantage over classical strategies when each is optimized for particle number.
Schmidt number for quantum operations

Huang Siendong
2006-01-01
To understand how entangled states behave under local quantum operations is an open problem in quantum-information theory. The Jamiolkowski isomorphism provides a natural way to study this problem in terms of quantum states. We introduce the Schmidt number for quantum operations by this duality and clarify how the Schmidt number of a quantum state changes under a local quantum operation. Some characterizations of quantum operations with Schmidt number k are also provided
Random number generation and creativity.
Bains, William
2008-01-01
A previous paper suggested that humans can generate genuinely random numbers. I tested this hypothesis by repeating the experiment with a larger number of highly numerate subjects, asking them to call out a sequence of digits selected from 0 through 9. The resulting sequences were substantially non-random, with an excess of sequential pairs of numbers and a deficit of repeats of the same number, in line with previous literature. However, the previous literature suggests that humans generate random numbers with substantial conscious effort, and distractions which reduce that effort reduce the randomness of the numbers. I reduced my subjects' concentration by asking them to call out in another language, and with alcohol - neither affected the randomness of their responses. This suggests that the ability to generate random numbers is a 'basic' function of the human mind, even if those numbers are not mathematically 'random'. I hypothesise that there is a 'creativity' mechanism, while not truly random, provides novelty as part of the mind's defence against closed programming loops, and that testing for the effects seen here in people more or less familiar with numbers or with spontaneous creativity could identify more features of this process. It is possible that training to perform better at simple random generation tasks could help to increase creativity, through training people to reduce the conscious mind's suppression of the 'spontaneous', creative response to new questions.
Unsolved problems in number theory
Guy, Richard K
1994-01-01
Unsolved Problems in Number Theory contains discussions of hundreds of open questions, organized into 185 different topics. They represent numerous aspects of number theory and are organized into six categories: prime numbers, divisibility, additive number theory, Diophantine equations, sequences of integers, and miscellaneous. To prevent repetition of earlier efforts or duplication of previously known results, an extensive and up-to-date collection of references follows each problem. In the second edition, not only extensive new material has been added, but corrections and additions have been included throughout the book.
Complex numbers in n dimensions
Olariu, Silviu
2002-01-01
Two distinct systems of hypercomplex numbers in n dimensions are introduced in this book, for which the multiplication is associative and commutative, and which are rich enough in properties such that exponential and trigonometric forms exist and the concepts of analytic n-complex function, contour integration and residue can be defined. The first type of hypercomplex numbers, called polar hypercomplex numbers, is characterized by the presence in an even number of dimensions greater or equal to 4 of two polar axes, and by the presence in an odd number of dimensions of one polar axis. The other type of hypercomplex numbers exists as a distinct entity only when the number of dimensions n of the space is even, and since the position of a point is specified with the aid of n/2-1 planar angles, these numbers have been called planar hypercomplex numbers. The development of the concept of analytic functions of hypercomplex variables was rendered possible by the existence of an exponential form of the n-complex numbe...

Full Text Available Recently, many mathematicians have studied different kinds of the Euler, Bernoulli, and Genocchi numbers and polynomials. In this paper, we give another definition of polynomials Ũn(x. We observe an interesting phenomenon of “scattering” of the zeros of the polynomials Ũn(x in complex plane. We find out some identities and properties related to polynomials Ũn(x. Finally, we also derive interesting relations between polynomials Ũn(x, Stirling numbers, central factorial numbers, and Euler numbers.
BKP and projective Hurwitz numbers
Natanzon, Sergey M.; Orlov, Aleksandr Yu.

We consider d-fold branched coverings of the projective plane RP^2 and show that the hypergeometric tau function of the BKP hierarchy of Kac and van de Leur is the generating function for weighted sums of the related Hurwitz numbers. In particular, we get the RP^2 analogues of the CP^1 generating functions proposed by Okounkov and by Goulden and Jackson. Other examples are Hurwitz numbers weighted by the Hall-Littlewood and by the Macdonald polynomials. We also consider integrals of tau functions which generate Hurwitz numbers related to base surfaces with arbitrary Euler characteristics sc {e}, in particular projective Hurwitz numbers sc {e}=1.

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)

From natural numbers to quaternions
Kramer, Jürg
2017-01-01
This textbook offers an invitation to modern algebra through number systems of increasing complexity, beginning with the natural numbers and culminating with Hamilton's quaternions. Along the way, the authors carefully develop the necessary concepts and methods from abstract algebra: monoids, groups, rings, fields, and skew fields. Each chapter ends with an appendix discussing related topics from algebra and number theory, including recent developments reflecting the relevance of the material to current research. The present volume is intended for undergraduate courses in abstract algebra or elementary number theory. The inclusion of exercises with solutions also makes it suitable for self-study and accessible to anyone with an interest in modern algebra and number theory.
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.
Low energy fermion number violation
International Nuclear Information System (INIS)
Peccei, R.D.
1989-01-01
After a brief aside on charge quantization in the standard electroweak theory, I concentrate on various aspects of anomaly induced fermion number violation in the standard model. A critical analysis of the role of sphalerons for the universe's baryon asymmetry is presented and the importance of calculating directly fermion number violating Green's functions is stressed. A physical interpretation of the recent observation of Ringwald, that coherent effects in the electroweak theory lead to catastrophic fermion number violation at 100 TeV, is discussed. Possible quantum effects which might spoil this semi-classical picture are examined

After listing functional constraints on what numbers in the brain must do, I sketch the two's complement fixed-point representation of numbers because it has stood the test of time and because it illustrates the non-obvious ways in which an effective coding scheme may operate. I briefly consider its neurobiological implementation. It is easier to imagine its implementation at the cell-intrinsic molecular level, with thermodynamically stable, volumetrically minimal polynucleotides encoding the remembered numbers, than at the circuit level, with plastic synapses encoding them.This article is part of a discussion meeting issue 'The origins of numerical abilities'. © 2017 The Author(s).

Additive theory of prime numbers
Hua, L K
2009-01-01
Loo-Keng Hua was a master mathematician, best known for his work using analytic methods in number theory. In particular, Hua is remembered for his contributions to Waring's Problem and his estimates of trigonometric sums. Additive Theory of Prime Numbers is an exposition of the classic methods as well as Hua's own techniques, many of which have now also become classic. An essential starting point is Vinogradov's mean-value theorem for trigonometric sums, which Hua usefully rephrases and improves. Hua states a generalized version of the Waring-Goldbach problem and gives asymptotic formulas for the number of solutions in Waring's Problem when the monomial x^k is replaced by an arbitrary polynomial of degree k. The book is an excellent entry point for readers interested in additive number theory. It will also be of value to those interested in the development of the now classic methods of the subject.

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.

The MIXMAX random number generator
Savvidy, Konstantin G.
2015-11-01
In this paper, we study the randomness properties of unimodular matrix random number generators. Under well-known conditions, these discrete-time dynamical systems have the highly desirable K-mixing properties which guarantee high quality random numbers. It is found that some widely used random number generators have poor Kolmogorov entropy and consequently fail in empirical tests of randomness. These tests show that the lowest acceptable value of the Kolmogorov entropy is around 50. Next, we provide a solution to the problem of determining the maximal period of unimodular matrix generators of pseudo-random numbers. We formulate the necessary and sufficient condition to attain the maximum period and present a family of specific generators in the MIXMAX family with superior performance and excellent statistical properties. Finally, we construct three efficient algorithms for operations with the MIXMAX matrix which is a multi-dimensional generalization of the famous cat-map. First, allowing to compute the multiplication by the MIXMAX matrix with O(N) operations. Second, to recursively compute its characteristic polynomial with O(N2) operations, and third, to apply skips of large number of steps S to the sequence in O(N2 log(S)) operations.

Philanthropy aimed at helping medical research has been around for a long time. In the 19th century, cash awards were distributed by the French Academy of Medicine according to criteria determined by each generous donor. It was thus that Mrs. Bernard de Civrieux endowed the Academy each year with the task of supporting one or more laureates whose work furthered understanding of "nervous diseases". In 1903, Raymond Cestan (1872-1933) and Claudien Philippe (1866-1903) were selected for their dissertation on "cerebral disturbances" during multiple sclerosis with clinical as well as anatomical-pathological effects. Never published, this innovative manuscript, taken from the library of Fulgence Raymond (1844-1910), will be analysed here after a brief biography of each author.

Full Text Available Manuscript Évora, Biblioteca Pública, Cód. CLI/1-3 is a small volume made up of two originally independent manuscripts datable respectively to c.1615 and c.1575, which were bound together sometime in the seventeenth century. The second part of the volume contains what is possibly the oldest, most persistent and widely-circulated of Holy Week series of responsories in extant late-sixteenth- and seventeenth-century Portuguese sources of polyphony. The first part is dominated by the works of Manuel Mendes, a composer whose considerable reputation rested especially on his abilities as a teacher, but whose works are among the most widespread pieces in Portuguese and American colonial manuscripts in the years around 1600. In this paper I will determine the origin of Évora Cód. CLI/1-3 by following the steps of Mendes’s career, and establish the relationship between this source and several other important manuscripts as to the transmission of two exemplary pieces through the study of variant readings and the rates of agreement of the sources in the points of variation, proposing a general stemmata for pieces in late-sixteenth and earlyseventeenth- century Portuguese sources of polyphony.

Experimental determination of Ramsey numbers.
Bian, Zhengbing; Chudak, Fabian; Macready, William G; Clark, Lane; Gaitan, Frank
2013-09-27
Ramsey theory is a highly active research area in mathematics that studies the emergence of order in large disordered structures. Ramsey numbers mark the threshold at which order first appears and are extremely difficult to calculate due to their explosive rate of growth. Recently, an algorithm that can be implemented using adiabatic quantum evolution has been proposed that calculates the two-color Ramsey numbers R(m,n). Here we present results of an experimental implementation of this algorithm and show that it correctly determines the Ramsey numbers R(3,3) and R(m,2) for 4≤m≤8. The R(8,2) computation used 84 qubits of which 28 were computational qubits. This computation is the largest experimental implementation of a scientifically meaningful adiabatic evolution algorithm that has been done to date.

Sequences, groups, and number theory
Rigo, Michel
2018-01-01
This collaborative book presents recent trends on the study of sequences, including combinatorics on words and symbolic dynamics, and new interdisciplinary links to group theory and number theory. Other chapters branch out from those areas into subfields of theoretical computer science, such as complexity theory and theory of automata. The book is built around four general themes: number theory and sequences, word combinatorics, normal numbers, and group theory. Those topics are rounded out by investigations into automatic and regular sequences, tilings and theory of computation, discrete dynamical systems, ergodic theory, numeration systems, automaton semigroups, and amenable groups. This volume is intended for use by graduate students or research mathematicians, as well as computer scientists who are working in automata theory and formal language theory. With its organization around unified themes, it would also be appropriate as a supplemental text for graduate level courses.
Negative numbers and antimatter particles
International Nuclear Information System (INIS)
Tsan, Ung Chan
2012-01-01
Dirac's equation states that an electron implies the existence of an antielectron with the same mass (more generally same arithmetic properties) and opposite charge (more generally opposite algebraic properties). Subsequent observation of antielectron validated this concept. This statement can be extended to all matter particles; observation of antiproton, antineutron, antideuton … is in complete agreement with this view. Recently antihypertriton was observed and 38 atoms of antihydrogen were trapped. This opens the path for use in precise testing of nature's fundamental symmetries. The symmetric properties of a matter particle and its mirror antimatter particle seem to be well established. Interactions operate on matter particles and antimatter particles as well. Conservation of matter parallels addition operating on positive and negative numbers. Without antimatter particles, interactions of the Standard Model (electromagnetism, strong interaction and weak interaction) cannot have the structure of group. Antimatter particles are characterized by negative baryonic number A or/and negative leptonic number L. Materialization and annihilation obey conservation of A and L (associated to all known interactions), explaining why from pure energy (A = 0, L = 0) one can only obtain a pair of matter particle antimatter particle — electron antielectron, proton and antiproton — via materialization where the mass of a pair of particle antiparticle gives back to pure energy with annihilation. These two mechanisms cannot change the difference in the number of matter particles and antimatter particles. Thus from pure energy only a perfectly symmetric (in number) universe could be generated as proposed by Dirac but observation showed that our universe is not symmetric, it is a matter universe which is nevertheless neutral. Fall of reflection symmetries shattered the prejudice that there is no way to define in an absolute way right and left or matter and antimatter

The visible light photon counter (VLPC) has the capability to discriminate photon number states, in contrast to conventional photon counters which can only detect the presence or absence of photons. We use this capability, along with the process of parametric down-conversion, to generate photon number states. We experimentally demonstrate generation of states containing 1, 2, 3 and 4 photons with high fidelity. We then explore the effect the detection efficiency of the VLPC has on the generation rate and fidelity of the created states

The most critical steps during the conservation-restoration treatment applied in Moroccan libraries are the deacidification using immersion in a saturated aqueous calcium hydroxide (Ca(OH)2) solution and the consolidation of degraded manuscripts using Japanese paper. The present study aims to assess the efficiency of this restoration method using a multi-analytical approach. For this purpose, three ancient Arabic Moroccan manuscript papers dating back to the 16th, 17th, and 18th centuries were investigated to characterize the paper support and make a comparative study between pre-restoration and post-restoration states. Three structural and molecular characterization techniques including solid-state nuclear magnetic resonance spectroscopy on (13)C with cross-polarization and magic-angle spinning nuclear magnetic resonance ((13)C CP-MAS NMR), attenuated total reflectance Fourier transform infrared spectroscopy (ATR FT-IR), and X-ray diffraction (XRD) were used to elucidate the cellulose main features, to identify the inorganic composition of the papers, and to study the crystallinity of the samples. Inductively coupled plasma atomic emission spectrometry (ICP-AES) allowed us to obtain a qualitative and quantitative characterization of the mineral fillers used in the manufacturing of the papers. Scanning electron microscopy coupled to energy dispersive spectrometry (SEM-EDS) ascertained the state of conservation of the different papers and helped us to study the elemental composition of the samples. After restoration, it was shown that the deacidification improved the stability of papers by providing an important alkaline buffer, as demonstrated using FT-IR and energy dispersive spectrometry (EDS) results. However, XRD and ICP-AES did not confirm the pertinence of the treatment for all samples because of the unequal distribution of Ca on the paper surface during the restoration. The consolidation process was studied using SEM analysis; its effectiveness in restoring

Residual number processing in dyscalculia.
Cappelletti, Marinella; Price, Cathy J
2014-01-01
Developmental dyscalculia - a congenital learning disability in understanding numerical concepts - is typically associated with parietal lobe abnormality. However, people with dyscalculia often retain some residual numerical abilities, reported in studies that otherwise focused on abnormalities in the dyscalculic brain. Here we took a different perspective by focusing on brain regions that support residual number processing in dyscalculia. All participants accurately performed semantic and categorical colour-decision tasks with numerical and non-numerical stimuli, with adults with dyscalculia performing slower than controls in the number semantic tasks only. Structural imaging showed less grey-matter volume in the right parietal cortex in people with dyscalculia relative to controls. Functional MRI showed that accurate number semantic judgements were maintained by parietal and inferior frontal activations that were common to adults with dyscalculia and controls, with higher activation for participants with dyscalculia than controls in the right superior frontal cortex and the left inferior frontal sulcus. Enhanced activation in these frontal areas was driven by people with dyscalculia who made faster rather than slower numerical decisions; however, activation could not be accounted for by response times per se, because it was greater for fast relative to slow dyscalculics but not greater for fast controls relative to slow dyscalculics. In conclusion, our results reveal two frontal brain regions that support efficient number processing in dyscalculia.

An introduction to Catalan numbers
Roman, Steven
2015-01-01
This textbook provides an introduction to the Catalan numbers and their remarkable properties, along with their various applications in combinatorics. Intended to be accessible to students new to the subject, the book begins with more elementary topics before progressing to more mathematically sophisticated topics. Each chapter focuses on a specific combinatorial object counted by these numbers, including paths, trees, tilings of a staircase, null sums in Zn+1, interval structures, partitions, permutations, semiorders, and more. Exercises are included at the end of book, along with hints and solutions, to help students obtain a better grasp of the material. The text is ideal for undergraduate students studying combinatorics, but will also appeal to anyone with a mathematical background who has an interest in learning about the Catalan numbers. “Roman does an admirable job of providing an introduction to Catalan numbers of a different nature from the previous ones. He has made an excellent choice o...
Strouhal number for free swimming
Saadat, Mehdi; van Buren, Tyler; Floryan, Daniel; Smits, Alexander; Haj-Hariri, Hossein
2015-11-01
In this work, we present experimental results to explore the implications of free swimming for Strouhal number (as an outcome) in the context of a simple model for a fish that consists of a 2D virtual body (source of drag) and a 2D pitching foil (source of thrust) representing cruising with thunniform locomotion. The results validate the findings of Saadat and Haj-Hariri (2012): for pitching foils thrust coefficient is a function of Strouhal number for all gaits having amplitude less than a certain critical value. Equivalently, given the balance of thrust and drag forces at cruise, Strouhal number is only a function of the shape, i.e. drag coefficient and area, and essentially a constant for high enough swimming speeds for which the mild dependence of drag coefficient on the speed vanishes. Furthermore, a dimensional analysis generalizes the findings. A scaling analysis shows that the variation of Strouhal number with cruising speed is functionally related to the variation of body drag coefficient with speed.

Full Text Available Suppose X, Y are manifolds, f,g:XÃ¢Â†Â’Y are maps. The well-known coincidence problem studies the coincidence set C={x:f(x=g(x}. The number m=dimÃ¢Â€Â‰XÃ¢ÂˆÂ’dimÃ¢Â€Â‰Y is called the codimension of the problem. More general is the preimage problem. For a map f:XÃ¢Â†Â’Z and a submanifold Y of Z, it studies the preimage set C={x:f(xÃ¢ÂˆÂˆY}, and the codimension is m=dimÃ¢Â€Â‰X+dimÃ¢Â€Â‰YÃ¢ÂˆÂ’dimÃ¢Â€Â‰Z. In case of codimension 0, the classical Nielsen number N(f,Y is a lower estimate of the number of points in C changing under homotopies of f, and for an arbitrary codimension, of the number of components of C. We extend this theory to take into account other topological characteristics of C. The goal is to find a Ã¢Â€Âœlower estimateÃ¢Â€Â of the bordism group ÃŽÂ©p(C of C. The answer is the Nielsen group Sp(f,Y defined as follows. In the classical definition, the Nielsen equivalence of points of C based on paths is replaced with an equivalence of singular submanifolds of C based on bordisms. We let Sp'(f,Y=ÃŽÂ©p(C/Ã¢ÂˆÂ¼N, then the Nielsen group of order p is the part of Sp'(f,Y preserved under homotopies of f. The Nielsen number Np(F,Y of order p is the rank of this group (then N(f,Y=N0(f,Y. These numbers are new obstructions to removability of coincidences and preimages. Some examples and computations are provided.
Gaussian distribution of LMOV numbers

Full Text Available Recent advances in knot polynomial calculus allowed us to obtain a huge variety of LMOV integers counting degeneracy of the BPS spectrum of topological theories on the resolved conifold and appearing in the genus expansion of the plethystic logarithm of the Ooguri–Vafa partition functions. Already the very first look at this data reveals that the LMOV numbers are randomly distributed in genus (! and are very well parameterized by just three parameters depending on the representation, an integer and the knot. We present an accurate formulation and evidence in support of this new puzzling observation about the old puzzling quantities. It probably implies that the BPS states, counted by the LMOV numbers can actually be composites made from some still more elementary objects.

We propose that the stability of dark matter is ensured by a discrete subgroup of the U(1){sub B-L} gauge symmetry, Z{sub 2}(B-L). We introduce a set of chiral fermions charged under the U(1){sub B-L} in addition to the right-handed neutrinos, and require the anomaly-cancellation conditions associated with the U(1){sub B-L} gauge symmetry. We find that the possible number of fermions and their charges are tightly constrained, and that non-trivial solutions appear when at least five additional chiral fermions are introduced. The Fermat theorem in the number theory plays an important role in this argument. Focusing on one of the solutions, we show that there is indeed a good candidate for dark matter, whose stability is guaranteed by Z{sub 2}(B-L).

Large number discrimination by mosquitofish.
Directory of Open Access Journals (Sweden)
Christian Agrillo
Full Text Available BACKGROUND: Recent studies have demonstrated that fish display rudimentary numerical abilities similar to those observed in mammals and birds. The mechanisms underlying the discrimination of small quantities (<4 were recently investigated while, to date, no study has examined the discrimination of large numerosities in fish. METHODOLOGY/PRINCIPAL FINDINGS: Subjects were trained to discriminate between two sets of small geometric figures using social reinforcement. In the first experiment mosquitofish were required to discriminate 4 from 8 objects with or without experimental control of the continuous variables that co-vary with number (area, space, density, total luminance. Results showed that fish can use the sole numerical information to compare quantities but that they preferentially use cumulative surface area as a proxy of the number when this information is available. A second experiment investigated the influence of the total number of elements to discriminate large quantities. Fish proved to be able to discriminate up to 100 vs. 200 objects, without showing any significant decrease in accuracy compared with the 4 vs. 8 discrimination. The third experiment investigated the influence of the ratio between the numerosities. Performance was found to decrease when decreasing the numerical distance. Fish were able to discriminate numbers when ratios were 1:2 or 2:3 but not when the ratio was 3:4. The performance of a sample of undergraduate students, tested non-verbally using the same sets of stimuli, largely overlapped that of fish. CONCLUSIONS/SIGNIFICANCE: Fish are able to use pure numerical information when discriminating between quantities larger than 4 units. As observed in human and non-human primates, the numerical system of fish appears to have virtually no upper limit while the numerical ratio has a clear effect on performance. These similarities further reinforce the view of a common origin of non-verbal numerical systems in all
DISCRETE MATHEMATICS/NUMBER THEORY

Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous. In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics such as integers, graphs, and statements do not vary smoothly in this way, but have distinct, separated values. Discrete mathematics therefore excludes topics in "continuous mathematics" such as calculus and analysis. Discrete objects can often be enumerated by ...

Highlights: ► A chaotic pseudorandom number generator (C-PRNG) poorly explores the key space. ► A C-PRNG is finite and periodic when implemented on a finite precision computer. ► We present a method to determine the period lengths of a C-PRNG. - Abstract: Because of the mixing and aperiodic properties of chaotic maps, such maps have been used as the basis for pseudorandom number generators (PRNGs). However, when implemented on a finite precision computer, chaotic maps have finite and periodic orbits. This manuscript explores the consequences finite precision has on the periodicity of a PRNG based on the logistic map. A comparison is made with conventional methods of generating pseudorandom numbers. The approach used to determine the number, delay, and period of the orbits of the logistic map at varying degrees of precision (3 to 23 bits) is described in detail, including the use of the Condor high-throughput computing environment to parallelize independent tasks of analyzing a large initial seed space. Results demonstrate that in terms of pathological seeds and effective bit length, a PRNG based on the logistic map performs exponentially worse than conventional PRNGs.

The proposed swimmer can swim with a special type of motion, which breaks the time-reversal symmetry. We also show that an ellipsoidal membrane with tangential travelling wave on it can also propel itself in the direction preferred by the travelling wave.

Fedosov's geometrical fixed-point equation for a differential is rewritten in a form similar to the functional equation for the generating function of Catalan numbers. This allows us to guess the solution. An adapted example for Kaehler manifolds of constant sectional curvature is considered in detail.

Full Text Available In reply to a problem of Jean Leray (application of the Nielsen theory to differential equations, two main approaches are presented. The first is via Poincaré's translation operator, while the second one is based on the Hammerstein-type solution operator. The applicability of various Nielsen theories is discussed with respect to several sorts of differential equations and inclusions. Links with the Sharkovskii-like theorems (a finite number of periodic solutions imply infinitely many subharmonics are indicated, jointly with some further consequences like the nontrivial -structure of solutions of initial value problems.

Signals of lepton number violation

The production of like-sign-dileptons (LSD), in the high energy lepton number violating ( Delta L=+2) reaction, pp to 2jets+l/sup +/l /sup +/, (l=e, mu , tau ), of interest for the experiments to be performed at the forthcoming Large Hadron Collider (LHC), is reported, taking up a composite model scenario in which the exchanged virtual composite neutrino is assumed to be a Majorana particle. Numerical estimates of the corresponding signal cross-section that implement kinematical cuts needed to suppress the standard model background, are presented which show that in some regions of the parameter space the total number of LSD events is well above the background. Assuming non-observation of the LSD signal it is found that LHC would exclude a composite Majorana neutrino up to 700 GeV (if one requires 10 events for discovery). The sensitivity of LHC experiments to the parameter space is then compared to that of the next generation of neutrinoless double beta decay ( beta beta /sub 0 nu /) experiment, GENIUS, and i...

Intersection numbers of spectral curves
Eynard, B.
2011-01-01
We compute the symplectic invariants of an arbitrary spectral curve with only 1 branchpoint in terms of integrals of characteristic classes in the moduli space of curves. Our formula associates to any spectral curve, a characteristic class, which is determined by the laplace transform of the spectral curve. This is a hint to the key role of Laplace transform in mirror symmetry. When the spectral curve is y=\\sqrt{x}, the formula gives Kontsevich--Witten intersection numbers, when the spectral curve is chosen to be the Lambert function \\exp{x}=y\\exp{-y}, the formula gives the ELSV formula for Hurwitz numbers, and when one chooses the mirror of C^3 with framing f, i.e. \\exp{-x}=\\exp{-yf}(1-\\exp{-y}), the formula gives the Marino-Vafa formula, i.e. the generating function of Gromov-Witten invariants of C^3. In some sense this formula generalizes ELSV, Marino-Vafa formula, and Mumford formula.

Full Text Available BACKGROUND: Research on human infants, mammals, birds and fish has demonstrated that rudimentary numerical abilities pre-date the evolution of human language. Yet there is controversy as to whether animals represent numbers mentally or rather base their judgments on non-numerical perceptual variables that co-vary with numerosity. To date, mental representation of number has been convincingly documented only for a few mammals. METHODOLOGY/PRINCIPAL FINDINGS: Here we used a training procedure to investigate whether mosquitofish could learn to discriminate between two and three objects even when denied access to non-numerical information. In the first experiment, fish were trained to discriminate between two sets of geometric figures. These varied in shape, size, brightness and distance, but no control for non-numerical variables was made. Subjects were then re-tested while controlling for one non-numerical variable at a time. Total luminance of the stimuli and the sum of perimeter of figures appeared irrelevant, but performance dropped to chance level when stimuli were matched for the cumulative surface area or for the overall space occupied by the arrays, indicating that these latter cues had been spontaneously used by the fish during the learning process. In a second experiment, where the task consisted of discriminating 2 vs 3 elements with all non-numerical variables simultaneously controlled for, all subjects proved able to learn the discrimination, and interestingly they did not make more errors than the fish in Experiment 1 that could access non-numerical information in order to accomplish the task. CONCLUSIONS/SIGNIFICANCE: Mosquitofish can learn to discriminate small quantities, even when non-numerical indicators of quantity are unavailable, hence providing the first evidence that fish, like primates, can use numbers. As in humans and non-human primates, genuine counting appears to be a 'last resort' strategy in fish, when no other

Using the Prime Focus CCD Camera at the Isaac Newton Telescope we have determined the form of the B and R galaxy number-magnitude count relations in 12 independent fields for 21 m ccd m and 19 m ccd m 5. The average galaxy count relations lie in the middle of the wide range previously encompassed by photographic data. The field-to-field variation of the counts is small enough to define the faint (B m 5) galaxy count to ±10 per cent and this variation is consistent with that expected from galaxy clustering considerations. Our new data confirm that the B, and also the R, galaxy counts show evidence for strong galaxy luminosity evolution, and that the majority of the evolving galaxies are of moderately blue colour.

Polynomials formalism of quantum numbers
International Nuclear Information System (INIS)
Kazakov, K.V.
2005-01-01
Theoretical aspects of the recently suggested perturbation formalism based on the method of quantum number polynomials are considered in the context of the general anharmonicity problem. Using a biatomic molecule by way of example, it is demonstrated how the theory can be extrapolated to the case of vibrational-rotational interactions. As a result, an exact expression for the first coefficient of the Herman-Wallis factor is derived. In addition, the basic notions of the formalism are phenomenologically generalized and expanded to the problem of spin interaction. The concept of magneto-optical anharmonicity is introduced. As a consequence, an exact analogy is drawn with the well-known electro-optical theory of molecules, and a nonlinear dependence of the magnetic dipole moment of the system on the spin and wave variables is established [ru

Radio frequency microelectromechanical system (RF MEMS) devices are microscale devices that achieve superior performance relative to other technologies by taking advantage of the accuracy, precision, materials, and miniaturization available through microfabrication. To do this, these devices use their mechanical and electrical properties to perform a specific RF electrical function such as switching, transmission, or filtering. RF MEMS has been a popular area of research since the early 1990s, and within the last several years, the technology has matured sufficiently for commercialization and use in commercial market systems.

Full Text Available While examining the genre of “The Stories of the Prophets” (Qiṣaṣ al-Anbiyā’ as background to my dissertation about Abraham in Islamic literature, I received from Prof. J. Sadan a manuscript that he found in the British Library that is related to this genre. Later I found similar versions of the same composition, which led me to try to find how this compilation emerged. The composition is very close to the preaching literature (wa‘ẓ, which deals mainly with moral education, but it also includes stories. I wondered if this is a literary genre, standing by itself, which started out as an aid, auxiliary material for understanding the oral tradition and religious studies, and then became an independent genre, closer to edifying literature, known as Paraenetica, or to the genre of Specula Regis (Mirrors of kings. I describe the manuscript in order to try to reach a conclusion: is this a different literary genre? Is it an educational genre or only a simplified version of stories for a child or a non-Arab ruler whose education was in Arabic language? Or did the writer perhaps want an original name for his compilation, and as the name Qiṣaṣ al-Anbiyā’ was already in use he chose a different name, using a word which also intimates the collection’s small size?

Multi-particle Anderson Localisation: Induction on the Number of Particles

This paper is a follow-up of our recent papers Chulaevsky and Suhov (Commun Math Phys 283:479-489, 2008) and Chulaevsky and Suhov (Commun Math Phys in press, 2009) covering the two-particle Anderson model. Here we establish the phenomenon of Anderson localisation for a quantum N-particle system on a lattice with short-range interaction and in presence of an IID external potential with sufficiently regular marginal cumulative distribution function (CDF). Our main method is an adaptation of the multi-scale analysis (MSA; cf. Froehlich and Spencer, Commun Math Phys 88:151-184, 1983; Froehlich et al., Commun Math Phys 101:21-46, 1985; von Dreifus and Klein, Commun Math Phys 124:285-299, 1989) to multi-particle systems, in combination with an induction on the number of particles, as was proposed in our earlier manuscript (Chulaevsky and Suhov 2007). Recently, Aizenman and Warzel (2008) proved spectral and dynamical localisation for N-particle lattice systems with a short-range interaction, using an extension of the Fractional-Moment Method (FMM) developed earlier for single-particle models in Aizenman and Molchanov (Commun Math Phys 157:245-278, 1993) and Aizenman et al.

Principal Component Analysis (PCA) is widely used in analytical chemistry, to reduce the dimensionality of a multivariate data set in a few Principal Components (PCs) that summarize the predominant patterns in the data. An accurate estimate of the number of PCs is indispensable to provide meaningful interpretations and extract useful information. We show how existing estimates for the number of PCs may fall short for datasets with considerable coherence, noise or outlier presence. We present here how Angle Distribution of the Loading Subspaces (ADLS) can be used to estimate the number of PCs based on the variability of loading subspace across bootstrap resamples. Based on comprehensive comparisons with other well-known methods applied on simulated dataset, we show that ADLS (1) may quantify the stability of a PCA model with several numbers of PCs simultaneously; (2) better estimate the appropriate number of PCs when compared with the cross-validation and scree plot methods, specifically for coherent data, and (3) facilitate integrated outlier detection, which we introduce in this manuscript. We, in addition, demonstrate how the analysis of different types of real-life spectroscopic datasets may benefit from these advantages of ADLS. Copyright © 2018 The Authors.

Hyperreal Numbers for Infinite Divergent Series

Treating divergent series properly has been an ongoing issue in mathematics. However, many of the problems in divergent series stem from the fact that divergent series were discovered prior to having a number system which could handle them. The infinities that resulted from divergent series led to contradictions within the real number system, but these contradictions are largely alleviated with the hyperreal number system. Hyperreal numbers provide a framework for dealing with divergent serie...

Fibonacci number of the tadpole graph
Directory of Open Access Journals (Sweden)
Joe DeMaio
2014-10-01
Full Text Available In 1982, Prodinger and Tichy defined the Fibonacci number of a graph G to be the number of independent sets of the graph G. They did so since the Fibonacci number of the path graph Pn is the Fibonacci number F(n+2 and the Fibonacci number of the cycle graph Cn is the Lucas number Ln. The tadpole graph Tn,k is the graph created by concatenating Cn and Pk with an edge from any vertex of Cn to a pendant of Pk for integers n=3 and k=0. This paper establishes formulae and identities for the Fibonacci number of the tadpole graph via algebraic and combinatorial methods.

Many basic ideas of algebra and number theory intertwine, making it ideal to explore both at the same time. Certain Number-Theoretic Episodes in Algebra focuses on some important aspects of interconnections between number theory and commutative algebra. Using a pedagogical approach, the author presents the conceptual foundations of commutative algebra arising from number theory. Self-contained, the book examines situations where explicit algebraic analogues of theorems of number theory are available. Coverage is divided into four parts, beginning with elements of number theory and algebra such as theorems of Euler, Fermat, and Lagrange, Euclidean domains, and finite groups. In the second part, the book details ordered fields, fields with valuation, and other algebraic structures. This is followed by a review of fundamentals of algebraic number theory in the third part. The final part explores links with ring theory, finite dimensional algebras, and the Goldbach problem.

Employing concepts from additive number theory, together with results on binary evaluations and partial series, we establish bounds on the density of 1's in the binary expansions of real algebraic numbers. A central result is that if a real y has algebraic degree D > 1, then the number {number_sign}(|y|, N) of 1-bits in the expansion of |y| through bit position N satisfies {number_sign}(|y|, N) > CN{sup 1/D} for a positive number C (depending on y) and sufficiently large N. This in itself establishes the transcendency of a class of reals {summation}{sub n{ge}0} 1/2{sup f(n)} where the integer-valued function f grows sufficiently fast; say, faster than any fixed power of n. By these methods we re-establish the transcendency of the Kempner--Mahler number {summation}{sub n{ge}0}1/2{sup 2{sup n}}, yet we can also handle numbers with a substantially denser occurrence of 1's. Though the number z = {summation}{sub n{ge}0}1/2{sup n{sup 2}} has too high a 1's density for application of our central result, we are able to invoke some rather intricate number-theoretical analysis and extended computations to reveal aspects of the binary structure of z{sup 2}.
Interaction of Number Magnitude and Auditory Localization.

The interplay of perception and memory is very evident when we perceive and then recognize familiar stimuli. Conversely, information in long-term memory may also influence how a stimulus is perceived. Prior work on number cognition in the visual modality has shown that in Western number systems long-term memory for the magnitude of smaller numbers can influence performance involving the left side of space, while larger numbers have an influence toward the right. Here, we investigated in the auditory modality whether a related effect may bias the perception of sound location. Subjects (n = 28) used a swivel pointer to localize noise bursts presented from various azimuth positions. The noise bursts were preceded by a spoken number (1-9) or, as a nonsemantic control condition, numbers that were played in reverse. The relative constant error in noise localization (forward minus reversed speech) indicated a systematic shift in localization toward more central locations when the number was smaller and toward more peripheral positions when the preceding number magnitude was larger. These findings do not support the traditional left-right number mapping. Instead, the results may reflect an overlap between codes for number magnitude and codes for sound location as implemented by two channel models of sound localization, or possibly a categorical mapping stage of small versus large magnitudes. © The Author(s) 2015.

This report is studied on CT number and CT images of the eight cases with fatty liver. Five of these cases showed the reversal of densities of the liver and vessels. In these cases, the diagnoses of the fatty liver were easible. In other cases, the diagnoses were possible only by comparison of the CT number of the liver and spleen because the CT number of normal liver were higher than those of the spleen. In the results which we examined the correlation of the CT number and specific gravities of the blood, normal saline, distilled water, mayonnaise, eatable iol, ethyl alcohol and lard, we observed the linear relationship between CT number and specific gravities. And so, we think that the diagnosis of the fatty liver and the degree of fatty infiltration can be guessed by the CT number of the liver and spleen. (author)

Full Text Available Dewey Decimal Classification is a most popular classification system in the world because of its completeness and most up-to-date. There are many optional number in this classification system, although it rarely to be discussed even it is important to known well about that optional number, especially for a librarian as classifier. This paper is a literature study about Dewey Decimal Classification Edition 23, to describe about optional numbers, particularly the number in relationship with Indonesia’s subject and discipline. This paper is to avoid misunderstanding in interpreted about optional number among librarians, especially for who that does not understand well about optional numbers.
Self-correcting random number generator
Humble, Travis S.; Pooser, Raphael C.
2016-09-06
A system and method for generating random numbers. The system may include a random number generator (RNG), such as a quantum random number generator (QRNG) configured to self-correct or adapt in order to substantially achieve randomness from the output of the RNG. By adapting, the RNG may generate a random number that may be considered random regardless of whether the random number itself is tested as such. As an example, the RNG may include components to monitor one or more characteristics of the RNG during operation, and may use the monitored characteristics as a basis for adapting, or self-correcting, to provide a random number according to one or more performance criteria.
Relativistic theory of tidal Love numbers

In Newtonian gravitational theory, a tidal Love number relates the mass multipole moment created by tidal forces on a spherical body to the applied tidal field. The Love number is dimensionless, and it encodes information about the body's internal structure. We present a relativistic theory of Love numbers, which applies to compact bodies with strong internal gravities; the theory extends and completes a recent work by Flanagan and Hinderer, which revealed that the tidal Love number of a neutron star can be measured by Earth-based gravitational-wave detectors. We consider a spherical body deformed by an external tidal field, and provide precise and meaningful definitions for electric-type and magnetic-type Love numbers; and these are computed for polytropic equations of state. The theory applies to black holes as well, and we find that the relativistic Love numbers of a nonrotating black hole are all zero.

Distinct functional pathways for processing words and numbers have been hypothesized from the observation of dissociated impairments of these categories in brain-damaged patients. We aimed to identify the cortical areas involved in Arabic number reading process in patients operated on for various brain lesions. Direct cortical electrostimulation was prospectively used in 60 brain mappings. We used object naming and two reading tasks: alphabetic script (sentences and number words) and Arabic number reading. Cortical areas involved in Arabic number reading were identified according to location, type of interference, and distinctness from areas associated with other language tasks. Arabic number reading was sustained by small cortical areas, often extremely well localized (area (Brodmann area 45), the anterior part of the dominant supramarginal gyrus (Brodmann area 40; p area (Brodmann area 37; p areas.

Stereological cell counting was applied to post-mortem neocortices of human brains from 31 normal individuals, age 18-93 years, 18 females (average age 65 years, range 18-93) and 13 males (average age 57 years, range 19-87). The cells were differentiated in astrocytes, oligodendrocytes, microglia...... while the total astrocyte number is constant through life; finally males have a 28% higher number of neocortical glial cells and a 19% higher neocortical neuron number than females. The overall total number of neocortical neurons and glial cells was 49.3 billion in females and 65.2 billion in males...... and neurons and counting were done in each of the four lobes. The study showed that the different subpopulations of glial cells behave differently as a function of age; the number of oligodendrocytes showed a significant 27% decrease over adult life and a strong correlation to the total number of neurons...
THE DISCOUNTED REPRODUCTIVE NUMBER FOR EPIDEMIOLOGY
Reluga, Timothy C.; Medlock, Jan; Galvani, Alison
2009-01-01
The basic reproductive number, , and the effective reproductive number, , are commonly used in mathematical epidemiology as summary statistics for the size and controllability of epidemics. However, these commonly used reproductive numbers can be misleading when applied to predict pathogen evolution because they do not incorporate the impact of the timing of events in the life-history cycle of the pathogen. To study evolution problems where the host population size is changing, measur...

The pseudo-random number generator (RNG) was written to match needs of nuclear and high-energy physics computation which in some cases require very long and independent random number sequences. In this random number generator the repetition period is about 10 36 what should be sufficient for all computers in the world. In this article the test results of RNG correlation, speed and identity of computations for PC, Sun4 and VAX computer tests are presented

An exact number conserving approach is formulated in the quasiparticle representation to show the effect of the particle-number projection on the ground and the first 0+ excited states. It is applied to the two-level pairing model, which allows an exact solution and a comparison to other approaches. The present method has proved to be an advantageous alternative as compared to the BCS and to the usual methods used to restore the particle number symmetry. (author)

A new approach is suggested for the anomalous nonconservation of baryon number in the electroweak theory at high temperatures. Arguments are presented in support of the idea that the baryon-number changing reactions may be viewed as random Markov processes. Making use of the general theory of Markov processes, the Fokker--Planck equation for the baryon-number distribution density is obtained and kinetic coefficients are calculated

Asymptotics of quantum weighted Hurwitz numbers
Harnad, J.; Ortmann, Janosch
2018-06-01
This work concerns both the semiclassical and zero temperature asymptotics of quantum weighted double Hurwitz numbers. The partition function for quantum weighted double Hurwitz numbers can be interpreted in terms of the energy distribution of a quantum Bose gas with vanishing fugacity. We compute the leading semiclassical term of the partition function for three versions of the quantum weighted Hurwitz numbers, as well as lower order semiclassical corrections. The classical limit is shown to reproduce the simple single and double Hurwitz numbers studied by Okounkov and Pandharipande (2000 Math. Res. Lett. 7 447–53, 2000 Lett. Math. Phys. 53 59–74). The KP-Toda τ-function that serves as generating function for the quantum Hurwitz numbers is shown to have the τ-function of Okounkov and Pandharipande (2000 Math. Res. Lett. 7 447–53, 2000 Lett. Math. Phys. 53 59–74) as its leading term in the classical limit, and, with suitable scaling, the same holds for the partition function, the weights and expectations of Hurwitz numbers. We also compute the zero temperature limit of the partition function and quantum weighted Hurwitz numbers. The KP or Toda τ-function serving as generating function for the quantum Hurwitz numbers are shown to give the one for Belyi curves in the zero temperature limit and, with suitable scaling, the same holds true for the partition function, the weights and the expectations of Hurwitz numbers.

Full Text Available Given a graph $G$, the total dominator coloring problem seeks a proper coloring of $G$ with the additional property that every vertex in the graph is adjacent to all vertices of a color class. We seek to minimize the number of color classes. We initiate to study this problem on several classes of graphs, as well as finding general bounds and characterizations. We also compare the total dominator chromatic number of a graph with the chromatic number and the total domination number of it.
