Audio Files in Binary Format and Corresponding .wav File for Payload Data in Communication Systems
No full textThis dataset contains audio files (in both binary uint8 format and .wav) used as the payload data for a communication system simulated as part of the project titled "Stochastic Spectrum Prediction via Diffusion Probabilistic Models and Representation Learning" by Chaoyi He, Arya Menon, and Linda Katehi.
Audio files in .wav format were randomly selected from the internet sources below, trimmed to a length between 1e6 and 8e6 samples, and converted into binary unit8 format using MATLAB software. The binary files and the corresponding audio files are available for download via this dataset.
Sources for the original audio files are listed below:

Ideal Baseband HE-SU 802.11 ax Downlink WiFi Signals with 20 MHz Bandwidth
No full textThis dataset consists IQ samples of ideal, single-user (HE-SU), 20 MHz bandwidth, downlink 802.11ax WiFi signals. The signals are generated using the WLAN toolbox in MATLAB (version R2021b). The sampling rate used for data generation is 20 MHz. The payload consists of random bits and each signal (data file) consists of five packets with no idle time between each packet. The IQ samples from each signal are stored as complex column vector in file WLAN802-11ax_data_#, where # is an integer used to index the file name. The corresponding file WLAN802-11ax_parameters_# consists of the unique configuration parameters used to generate the data file. If multiple transmit antennas (multiple data streams) are present, then each data stream is entered as a column vector in the data file. Details on the configuration settings are listed in the Readme available with this dataset
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
No full textWe 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
