Design of NML Circuits based on M-RAM
NanoMagnet Logic (NML) is an emerging technol- ogy that allows to design digital circuits using nanomagnets. Each magnet has only two possible states and encodes digital informa- tion without the need for currents or voltages. This behavior differentiates NML circuits from charge based technologies. The advantages provided by NML circuits are a possible very low power consumption, and the ability to mix logic and memory in the same device. While a rich experimental activity on NML circuits can be found in literature, the feasibility of a complete NML system remains to be demonstrated yet. In this work we explore the possibility of implementing NML logic circuits based on the physical structure of Magnetic RAM (M-RAM). The advantages are twofold: First, M-RAM is a well developed technology, ready for the commercial stage, second it intrinsically provides an interface toward the CMOS world. To demonstrate the feasibility of NML circuits based on M-RAM we have designed a 3-input Ex-OR gate, using two different physical layouts for control signals. The first solution is strictly based on the M-RAM structure; the second solution requires a more complex fabrication process but leads to a smaller area. Circuits are simulated using VHDL language, with the aid of a tool that we have developed which automatically generates the VHDL code starting from the circuit layout. Overall, the solution here presented is a considerable step-forward toward the development of a complete magnetic circui
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
M-RAM: a Mobile Risk Assessment Method for Enterprise Mobile Security
Mobile solutions seem to outrun the control and governance within enterprise organizations. The acceptance of smartphones and tablets in business has gone at such a high pace that organizations are no longer able to oversee the risks of their mobile usage. Traditional risk assessment methods do not consider usage of mobile devices— mobility—despite the fact that enterprise organizations struggle with managing mobile risks. We aim to fill this gap by introducing a Mobile Risk Assessment Method (M-RAM). The method is based on an evaluation of industry standard risk methods and 22 interviews with mobile security experts. Three components compose the method: (1) a risk assessment process that is customized for mobility, (2) involved entities that oppose risks, and (3) attention areas that can contain vulnerabilities as well as controls. Moreover, the study provides a practical work program to conduct the M-RAM and validates the approach by conducting a case study
