Global mapping of scientific information exchange using altmetric data

Quality and Quantity 2019年第2期53卷 935-955页

This study seeks to provide new insights into a hidden pattern in the cross-national scholarly network structure from an altmetric perspective. We investigate and visualize the dynamic and complex nature of altmetric-based referrals using a social network algorithm that measures societal use (via Twitter) and scientific impact (via Mendeley). We also use a variety of network indices and a QAP (quadratic assignment procedure) to validate the structural relationships between inter-country sharing networks. Finally, we identify several groups including Asia, Europe, and North America through a transcontinental sharing analysis. The findings suggest that policymakers need to track the international routes of word-of-mouth, which constitute socially mediated data-sharing, regarding scientific publications. © 2018, Springer Nature B.V.

In this paper, we investigate the average symbol error probability (SEP) of fixed decode-and-forward relay networks over independent but not identically distributed Nakagami-m fading channels. We have derived closed form expression of SEP for general rectangular quadrature amplitude modulation (QAM) under relay selection scheme where only the best relay forwards message from the source to the destination. The expressions are in terms of hypergeometric series which can be efficiently numerically evaluated. The numerical results are validated with Monte-Carlo simulations. ©2010 IEEE.

In this research, we propose a humming-to-instrument conversion system based on cycle-consistent adversarial networks (CycleGAN) to convert human humming to the sound of viola. This research adjusts the weight of cycle-consistency loss and identity loss to successfully convert the sound. From the experimental results of objective RMSE, the converted audio is more similar to viola compared to the similarity to humming. From the results of subjective MOS, the quality of the converted sound is fair to listeners. © 2021 IEEE.

A project conducted by faculty in Bagley College of engineering at Mississippi State University to improve the writing-evaluation of graduate teaching assistants (TAs) in charge of undergraduate laboratories in electrical and computer engineering (ECE). The project began by using writing tutors to work with lab TAs on quality and consistency of their lab-report grading. Results from early exam administrations showed the need for TA support both before and after the exam as well as ongoing performance evaluation. The results show that the every student who took the ESL course performed better on the exam the second time with an average improvement of 57%.

In this paper, we propose an extension to our previous work on food portion size estimation using a single image and a multi-view volume estimation method. The single-view technique estimates food volume by using prior information (segmentation and food labels) generated from food identification methods we described earlier. For multi-view volume estimation, we use "Shape from Silhouettes" to estimate the food portion size. The experimental results of our volume estimation methods demonstrate our results with respect to accuracy and reliability. © Copyright 2013 ACM.

One measure of continuous improvement in the Electrical and computer engineering Department (ECE) at the University of North Carolina at Charlotte is survey feedback from alumni on their workplace readiness. In a recent survey, alumni highlighted oral communication as an area of weakness in the curriculum. When a group of faculty teaching design courses learned about the University's communication Across the Curriculum (CAC) program, they formed a pilot team to focus on improving student oral presentation skills in the design courses. The CAC program focuses on the oral and written communication as playing an integral role in teaching students reasoning, critical thinking, and problem solving skills. And as faculty development program, it seeks to develop a communication enhanced curriculum (CEC) at the departmental level. The CAC program hosts an annual institute during which departmental teams gain professional development in the areas of oral and written communication. At the 2010 CAC Institute, a team of ECE faculty set the strategic goal to improve ECE students' ability to clearly convey technical information orally during design presentations. The ECE team then met with the CAC coordinator to develop an oral communication rubric for uniform implementation, thus establishing a cohesive assessment across the department's design sequence. Our goal with this approach was to improve oral communication skills among our graduates to increase their opportunities for success in their professional careers. We focused on three important skills in oral presentation: Audience analysis, message coherence / focus, and message delivery. A team of five faculty-four from ECE and the CAC director-worked together to develop a rubric to evaluate students oral presentation skills in the sophomore design (ECGR 2252), junior design (ECGR 3157) and senior design (ECGR3253 and ECGR3254) courses. The implementation of the process began by using the rubric in Appendix (a) to evaluate stu

Majorization theoretical approach to entanglement enhancement via local filtration

From the perspective of majorization theory, we study how to enhance the entanglement of a two-mode squeezed vacuum (TMSV) state by using local filtration operations. We present several schemes achieving entanglement enhancement with photon addition and subtraction, and then consider filtration as a general probabilistic procedure consisting in acting with local (nonunitary) operators on each mode. From this, we identify a sufficient set of two conditions for these filtration operators to successfully enhance the entanglement of a TMSV state, namely, the operators must be Fock orthogonal (i.e., preserving the orthogonality of Fock states) and Fock amplifying (i.e., giving larger amplitudes to larger Fock states). Our results notably prove that ideal photon addition, subtraction, and any concatenation thereof always enhance the entanglement of a TMSV state in the sense of majorization theory. We further investigate the case of realistic photon addition (subtraction) and are able to upper bound the distance between a realistic photon-added (-subtracted) TMSV state and a nearby state that is provably more entangled than the TMSV, thus extending entanglement enhancement to practical schemes via the use of a notion of approximate majorization. Finally, we consider the state resulting from k-photon addition (on each of the two modes) on a TMSV state. We prove analytically that the state corresponding to k=1 majorizes any state corresponding to 2≤k≤8 and we conjecture the validity of the statement for all k≥9.

Organic Transistor (OT) modeling, fabrication and applicability has undergone remarkable progress during last ten years. Organic Thin Film Transistors (OTFTs) have received significant attention recently because of their considerable utility. They can be fabricated at lower temperature and significantly reduced cost as compared to Hydrogenated Amorphous Silicon Thin Film Transistors (a-Si: H TFTs). Fabrication of OTFTs at low temperature allows utilization of wide range of substrates, thereby permitting usage of organic transistors as future candidate for many low-cost electronics applications that require flexible polymeric substrates such as RFID tags, smart cards, electronic paper, and active matrix flat panel displays. This paper provides detailed insight of OTFTs, their operating principles, device materials and various structures such as Top Gate Top Contact (TGTC), Top Gate Bottom Contact (TGBC), Bottom Gate Top Contact (BGTC) and Bottom Gate Bottom Contact (BGBC). Although OTFTs find tremendous and widespread applications, but is marred by few limitations related to factors such as speed, compatibility, stability, degradability and variability. This paper comprehensively discusses the performance and limitations of OTFTs. © 2012 Springer-Verlag GmbH.
