Video visual scene displays (Babb et al., 2021)
No full textPurpose: Social interaction poses many challenges for adolescents with autism spectrum disorder (ASD) and complex communication needs. The purpose of this study was to investigate the impact of video visual scene displays (video VSDs) on communication during interactions between adolescents with ASD and peer partners.Method: This study used an across-participant multiple-baseline single-case experimental design. Four adolescents with ASD and complex communication needs were taught to use video VSDs, presented on a tablet-based app, during social interactions with peer partners in a high school setting. The video VSDs used during the interactions were selected (and programmed with vocabulary) based on the interests of the adolescent with ASD and their peer partner.Results: Following the introduction of the video VSD intervention, all four adolescents with ASD demonstrated an increase in communicative turns compared to baseline (Tau-U = 1.0, 95% CI [0.56, 1]), and all four increased in modes of communication used. Increased use of speech also was observed for the three participants who made use of speech prior to the intervention. All participants with ASD (and their peer partners) expressed an interest in continued use of the video VSD app to support social interaction.Conclusion: The use of video VSDs may be a viable option to increase the participation and communication of adolescents with ASD during social interactions with peer partners.Supplemental Material S1.

Schematic comparison of BabA, BabB, and BabC.
No full text<p>The representative structures of BabA and BabB are based on the J99 amino acid sequence, whereas the structure of BabC is based on the consensus sequence defined in this study. The N-HR indicates N-terminal homology region, M-VR indicates middle variable region, which is characterized by sequence difference among the three Bab proteins. Note that the M-VR is conserved for each of the Bab proteins. The C-HR indicates C-terminal homologous region that shows >90% identity. The CT-R present at the N-terminus of BabB refers to the CT repeat region. VR-1 and VR-2 in BabC indicate regions of variability among the BabC amino acid sequences analyzed in this study (n = 15).</p
Towards Software Defined Radio (SDR) Bluetooth and IEEE802.11b Modem Integration
No full textThis paper describes Complementary Code Keying with Differential Quadrature Phase Shift Keying (CCK+DQPSK) modulation, as used, for example, in the IEEE802.11b standard, and Gaussian Frequency Shift Keying (GFSK) modulation, as used, ofr example, in the Bluetooth standard. It indicates how the different types of modulation schemes might be more efficiently integrated to produce a modem capable of working with either modulation scheme. The paper presents a novel Multi Mode integrated Modem architecture, making use of: 1) programmable soft circuits 2) adaptive switching 3) adaptive FIR configuration 4) adaptive FIR functionality (same FIR, different function, e.g. correlation/matched filtering) 5) extended look-up table functionality Results are presented, indicating the performance of the integrated modem. Finally, implementation issues are discussed together with a way forward for further work in this area
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
