Facial expression recognition using a multi-level convolutional neural network

Even though many breakthroughs have been made in image classification, especially in facial expression recognition, this research area is still challenging in terms of wild sampling environment. In this work, we carry out a study of multi-level features in a convolutional neural network for facial expression recognition. Based on our observations, we introduce a model by classification task. Our model was evaluated on the FER2013 dataset and achieved a comparable performance to the current state-of-the-art methods.
Der Capability Approach in der musikpädagogischen Teilhabeforschung. Empirische Anwendung eines capability-basierten Modells der Teilhabe an Musikkultur.

Das Entstehen zahlreicher musikalischer Bildungsangebote legitimiert sich nicht selten aus der Forderung nach mehr Teilhabegerechtigkeit. „Jedem Kind ein Instrument“ ist hierfür ein Beispiel. Der Artikel widmet sich der Entwicklung und Anwendung eines Modells der Teilhabe an Musikkultur auf der Basis des Capability Approach. In diesem auf das Individuum fokussierten Rahmen werden das domänenspezifische und das allgemeine well-being (i. S. von Lebenszufriedenheit) als individuelle Indikatoren für das Gelingen der Teilhabe an Musikkultur und für die Beurteilung von Teilhabegerechtigkeit einbezogen.Die empirische Anwendung des Modells erfolgt im Rahmen einer Analyse der Teilhabe an Musikkultur in Klassenstufe 7. Es kann gezeigt werden, dass sich auf der Basis von domänenspezifischem well-being und der Teilhabe an Musikkultur vier unterschiedliche Teilhabeprofile bilden lassen. Teilhaben und nicht-teilhaben nicht als einfache Dichotomie zu betrachten. Insgesamt können wichtige inhaltliche Annahmen des Teilhabe-Modells bestätigt werden, was die Produktivität des Capability Approach für die musikpädagogische Teilhabeforschung bestätigt. Schlagwörter: JeKi, Capability Approach, kulturelle Teilhabe, Teilhabegerechtigkeit, well-being
Two-Tier Performance Based Classification Model for Low Level NLP tasks

An error in classification can occur due to an error of omission, statistically known as a false negative or an error of commission, statistically known as a false positive. In order to build a perfect classifier, the false negatives and false positives have to be zero. With this in mind, we propose a two-tier model for the classifier. The first tier will reduce false negatives to zero and pass the results to the second tier. The second tier will reduce false positives to zero. We demonstrate the working of this model for the task of classifying sentences in Hindi as passive formations. The first tier will consist of a simple pattern matching system for filtering out sentences with likely passive formations without committing errors of omission. This will reduce the size of the corpus considerably. The second tier will work on the reduced corpus and make a complete grammatical analysis of these filtered sentences in order to reduce the false positives to a zero. The Anusaraka System [Bharati 1995] is a very good example of such a system. This paper concentrates on building the first tier. A hill climbing algorithm is proposed, where the start state is a list of patterns commonly found in passive formations. Each step up the hill will update the list of patterns such that the next state will bring down the number of false negatives, thereby reducing errors of omission. The hill climbing algorithm terminates when the false negatives are zero.
Evaluation of the SEE sensitivity and methodology for error rate prediction of applications implemented in Multi-core and Many-core processors

The present thesis aims at evaluating the SEE static and dynamic sensitivity of three different COTS multi-core and many-core processors. The first one is the Freescale P2041 multi-core processor manufactured in 45nm SOI technology which implements ECC and parity in their cache memories. The second one is the Kalray MPPA-256 many-core processor manufactured in 28nm TSMC CMOS technology which integrates 16 compute clusters each one with 16 processor cores, and implements ECC in its static memories and parity in its cache memories. The third one is the Adapteva Epiphany E16G301 microprocessor manufactured in 65nm CMOS process which integrates 16 processor cores and do not implement protection mechanisms. The evaluation was accomplished through radiation experiments with 14 Mev neutrons in particle accelerators to emulate a harsh radiation environment, and by fault injection in cache memories, shared memories or processor registers, to simulate the consequences of SEUs in the execution of the program. A deep analysis of the observed errors was carried out to identify vulnerabilities in the protection mechanisms. Critical zones such as address tag and general purpose registers were affected during the radiation experiments. In addition, The Code Emulating Upset (CEU) approach, developed at TIMA Laboratory was extended to multi-core and many core processors for predicting the application error rate by combining the results issued from fault injection campaigns with those coming from radiation experiments.
Techniques for Formulation of Nanoemulsion Drug Delivery System: A Review

Nanoemulsion drug delivery systems are advanced modes for delivering and improving the bioavailability of hydrophobic drugs and the drug which have high first pass metabolism. The nanoemulsion can be prepared by both high energy and low energy methods. High energy method includes high-pressure homogenization, microfluidization, and ultrasonication whereas low energy methods include the phase inversion emulsification method and the self-nanoemulsification method. Low energy methods should be preferred over high energy methods as these methods require less energy, so are more efficient and do not require any sophisticated instruments. However high energy methods are more favorable for food grade emulsion as they require lower quantities of surfactant than low energy methods. Techniques for formulation of nanoemulsion drug delivery system are overlapping in nature, especially in the case of low energy methods. In this review, we have classified different methods for formulation of nanoemulsion systems based on energy requirements, nature of phase inversion, and self-emulsification.
Creating a new “reality” for medical education: the Nexus Reality Lab for virtual reality

Background The Technology Team at the Ruth Lilly Medical Library, Indiana University (IU), first started exploring virtual reality (VR) in 2016. In 2017, we began offering weekly sessions dubbed VRidays (“VR Fridays”) to give students an opportunity to experience the technology. We also purchased a portable VR setup that allowed us to demonstrate VR at our regional campuses. Description To lower the entry barrier to VR, the Technology Team collaborated with the IU Advanced Visualization Lab to establish a reality lab in our collaborative learning space. The lab opened in the fall of 2018 and consists of four high-end VR stations that are accessible to students at any time, but they can also make an appointment for a more guided experience. Information and instructions are available on a LibGuide. Conclusion We are currently collecting data on the number of unique users and evaluating application usage. We are working on a feedback mechanism and looking to develop collaborative partnerships across the university.
Benchmarking veterinary librarians’ participation in systematic reviews and scoping reviews

Objectives The objectives of this study were to benchmark roles that veterinary librarians at universities and colleges play in systematic reviews (SRs) and scoping reviews that are conducted by faculty and students at their institutions, to benchmark the level of training that veterinary librarians have in conducting SRs, to identify barriers to their participation in SRs, and to identify other types of literature reviews that veterinary librarians participate in. Methods Sixty veterinary librarians in universities and colleges in Canada, the United States, England, Scotland, Ireland, Australia, and New Zealand were surveyed online about their roles and training in conducting SRs, barriers to participation in SRs, and participation in other types of literature reviews. Results Veterinary librarians’ highest participation was at an advising level in traditional librarian roles as question formulator, database selector, search strategy developer, and reference manager. Most respondents reported pretty good to extensive training in traditional roles and no or some training in less traditional roles. Sixty percent of respondents received few or no requests to participate in SRs, and only half of respondents had participated in SRs as a review team member. Sixty percent of respondents stated that their libraries had no policies regarding librarian roles and participation in SRs. Conclusions The surveyed veterinary librarians participated in SRs to a lesser degree than human health sciences librarians, experienced low demand from veterinary faculty and students to participate in SRs, and participated as review team members at significantly lower rates than human health sciences librarians. The main barriers to participation in SRs were lack of library policies, insufficient training, and lack of time.
Formation control of UAVs based on artificial potential field

The problem of UAVs’ formation control in the process of motion is investigated in this paper. A formation control method based on artificial potential field of UAVs is proposed, established on the collision avoidance, aggregation and speed matching rules of UAVs. First establish the UAVs’ kinetic model in accordance to the motion rules, then design the formation control algorithm based on artificial potential field function, which is used to control the formation during the movement of UAVs. Finally, the results of simulation experiment show that the proposed formation control method in this paper is effective and has the advantages of easy realization, good real-time performance and excellent robustness.
Nutritional Evaluation of Enhanced Unsieved Ogi Paste with Garlic and Ginger

Ogi is a cheap and readily available health-sustaining fermented food in Africa. This study assessed the effect of enhancing unsieved ogi paste with garlic and ginger (2% and 4%) both individually and together on organoleptic acceptability and nutritional changes. These pastes were subjected to seven treatments at ambient and refrigerated temperatures for 4 weeks during which sensory analysis was carried out, and mineral content, total antioxidant activities, and proximate composition were evaluated. Ogi (maize) enhanced with 2% garlic+2% ginger and ogi (sorghum) enhanced with 4% garlic+2% ginger were most preferred. There was no significant difference in organoleptic evaluation of the preferred enhanced ogi pastes compared to the control samples. Crude protein ranged between 7.73~9.19% and 9.83~10.08% for control ogi, and between 7.76~8.36% and 10.07~10.92% in the maize and sorghum enhanced ogi pastes, respectively. The fat contents of all pastes were significantly different at P<0.05. Antioxidant properties of ogi paste were enhanced by ginger and garlic. Ogi supplemented with 4% garlic+2% ginger showed the highest radical scavenging activity (0.75~0.97 IC50 mg/mL). The results show that garlic and ginger either alone or in combination have potential to enhance the nutritional value of ogi pastes, and demonstrate the acceptability of using maize or sorghum as primary raw materials.

The imbalanced state of free-to-play game research: A literature review

As free-to-play games have increased their economic value, the research interest on them has increased as well. This article looks at free-to-play game research conducted so far through a systematic literature review and an explorative analysis of the documents included in the review. The results highlight an excessive focus especially on behavioral economic studies trying to maximize the player bases and profits, while other aspects, such as meaningful game experiences, cultural and societal implications, or critical review of the phenomena have been left in the marginal. Based on the review results, this article suggests four future agendas to reinforce the lacking areas of free-to-play game research.
Information seeking and evaluation: a multi-institutional survey of veterinary students

Objective To practice evidence-based medicine, clinicians must be competent in information literacy (IL). Few studies acknowledge the critical role that reading strategies play in IL instruction and assessment of health professional students. The purpose of this study was to understand the information-seeking and evaluation behaviors of doctor of veterinary medicine (DVM) students in regard to scientific papers. Methods The authors studied DVM student behaviors across eight programs in North America using a web-based survey of closed- and open-ended questions about finding and evaluating scientific papers, including a task to read a linked scientific paper and answer questions about it. Results A total of 226 individuals responded to the survey. The sections of a scientific paper that were most commonly read were the abstract, introduction, and conclusions. Students who reported reading a higher proportion of scientific papers were more likely to feel confident in their abilities to interpret them. A third of respondents answered open-ended questions after the paper reading task. Respondents felt the least amount of confidence with one of the final steps of evidence-based medicine, that of interpreting the significance of the paper to apply it in veterinary medicine. Conclusions DVM students may lack the skills needed to evaluate scientific literature and need more practice and feedback in evaluating and interpreting scientific papers. Librarians who support DVM students can (1) help DVM students to efficiently evaluate scientific literature, (2) seek training opportunities in alternative modes of teaching and learning IL skills, and (3) partner with veterinary faculty and clinicians to provide students with practice and feedback in information evaluation.
Different Frames of Players and the Motivation of Prosocial Behaviors in Digital Games

In digital games, players may behave as they do in the real world. In-game behaviors may have multiple complex motivations, like in the real world, or they may be inspired by the rules of the game. How in-game behaviors are motivated may differ between different players. The current study focuses on the difference between players who interpret the game as a mere rule-based play and players who perceive the game as a world with its own rules and norms. Among different in-game behaviors, this study specifically focuses on players’ prosocial behaviors. A survey was conducted to look at the relationship between the attitude toward prosocial behaviors, its motivation, and how each player frames the gameplay. The findings of this study revealed that the different frames of players were significantly related to the motivation of the players’ prosocial behavior toward other characters.
High and Very High Frequency Power Supplies for Industrial Applications

ecently, with the continuous development of industrial electronics technologies, small-size and high-powerdensity designs became a development trend. Thus, high and very high frequency power supplies received widespread attention. One major advantage of improving the working frequency is to achieve total volume reduction of passive components, and therefore effectively reduce system size and improve power density. Moreover, in some cases, even parasitic parameters of a system working at high and very high frequency can also be used as the passive element. Besides, electrolytic capacitors can be removed thereby greatly extending the system lifetime. The dynamic response can also be accelerated. At the same time, the third generation of wide bandgap semiconductors such as SiC and GaN with material properties superior to their Si counterparts, creates new opportunity and challenges for innovation of power converters such as compact design, thermal management, electromagnetic interference etc. With the maturity of these devices, it provides a broad space for development of high and very high frequency power supplies. Nevertheless, topologies, driving methods, control strategies and many aspects require deep investigation with the increment of switching frequencies. We encourage all researchers working in this area to submit papers to this Special Section. Editors invite original manuscripts presenting recent advances in these fields with special reference to the following topics:
Studies on Closing Time in Measuring Greenhouse Gas Emission from Dry Cropland by Static Chamber Method

By using continuous-automatic measurement system,the emission fluxes of different greenhouse gases from winter wheat fields in the North China Plain under typical climate conditions were continuously measured by the static chamber method.The process of emission flux changes of different greenhouse gases and closing time in the static chamber were analyzed.The results showed that the closing time in the static chamber should be within 25 minutes by measuring CO_2 emission,15~30 minutes by measuring N_2O emission and less than 30 minutes by measuring CH_4 emission respectively.These results have a significant reference to measurement of greenhouse gases emitted from cropland by using the static chamber method.
Assessing the Validity of the Verification Method as a Design Tool

Title of Thesis: ASSESSING THE VALIDITY OF THE VERIFICATION METHOD AS A DESIGN TOOL Maibritt Tulin Antonsen, Master of Science, 2017 Thesis Directed By: Professor, Dr. José L. Torero Department of Fire Protection Engineering The Verification Method (VM) as a design tool is becoming more widespread, resulting in a need for a critique of the concepts behind the method. This project provides the critique by extracting examples from the design processes and solutions of a building being designed using three different approaches: Performance-Based Design, Prescriptive Methods and the VM. The main perceived advantages of the VM is its time efficiency, accessibility and flexibility, while the observed weaknesses include substitution of the designer, the level of underand over-design and its lack of robustness of the performance criteria and guidance in areas such as fire modeling. It is uncovered how the VM is a design method rather than a tool to demonstrate compliance with the performance requirements of building codes, which was the original objective of the VM. The Verification Method must return to its original intentions in order to ensure its validity as a
In Vitro Antidiabetic and Antiobesity Activities of Traditional Kochujang and Doenjang and Their Components

In this study we investigated the antidiabetic and antiobesity effects of aqueous ethanol extracts of traditional kochujang and doenjang. The average α-glucosidase inhibitory activity and adipogenesis inhibitory activity for the kochujang samples were 29.6% and 20.8%, respectively, while those of the doenjang samples were 46.3% and 11.6%, respectively. Therefore, antidiabetic activity is high in doenjang and antiobesity activity is high in kochujang. Kochujang and doenjang components responsible for suppressing the functional effects were investigated by metabolomic analysis. For kochujang, p-coumaric acid, N6,N6,N6-trimethyllysine, threonine, and methionine positively correlated with inhibition of adipogenesis activity, whereas for doenjang, betaine and betaine aldehyde were thought to be responsible for the antidiabetic effects. As p-coumaric acid and betaine were the most probable candidates with functional effects, these two compounds were selected for further analysis. Inhibition of adipogenesis was shown to be 14.0±1.85% for betaine chloride and 38.3±3.27% for p-coumaric acid, suggesting that p-coumaric acid is more effective than betaine against obesity. However, betaine exhibited higher α-glucosidase inhibitory activity than p-coumaric acid. Our results suggest that both kochujang and doenjang can be used against diabetes and obesity. However, clinical trials are necessary to support these results.
MicroRNA-205-5p inhibits three-dimensional spheroid proliferation of ErbB2-overexpressing breast epithelial cells through direct targeting of CLCN3

We previously reported that microRNA-205-5p (miR-205-5p) is significantly decreased in the ErbB2-overexpressing breast epithelial cell line MCF10A-ErbB2 compared with control cells. In this study, we identified a direct target of miR-205-5p, chloride voltage-gated channel 3 (CLCN3). CLCN3 expression was induced by ErbB2 overexpression; this induced expression was then reduced to control levels by the transfection of the miR-205-5p precursor. In RNA-binding protein immunoprecipitation with Ago1/2/3 antibody, CLCN3 was significantly enriched in 293T embryonic kidney cells with miR-205-5p mimic transfection compared with negative control mimic transfection. In luciferase reporter assays using CLCN3 3′-UTR constructs, the miR-205-5p mimic significantly decreased reporter activity of both wild-type and partial mutant constructs in MCF10A-ErbB2 cells. In contrast, no inhibitory effects of the miR-205-5p mimic were detected using the complete mutant constructs. Since miR-205-5p expression in exosomes derived from MCF10A-neo cells was substantially higher than in exosomes derived from MCF10A-ErbB2 cells, we next investigated whether an exosome-mediated miR-205-5p transfer could control CLCN3 expression. To this end, exosomal miR-205-5p derived from MCF10A-neo cells was functionally transferred to MCF10A-ErbB2 cells, which served to decrease the expression of CLCN3. To assess the roles of CLCN3 in breast cancer, we next performed three-dimensional (3D) spheroid proliferation analyses using MCF10A-ErbB2 cells treated with MCF10A-neo-derived exosomes or CLCN3 shRNA stably expressing SKBR3 and MDA-MB-453 breast cancer cells. Our results showed that both treatment with MCF10A-neo-derived exosome and CLCN3 shRNA expression suppressed 3D spheroid proliferation. Collectively, these novel findings suggest that CLCN3 may be a novel direct target of miR-205-5p and this CLCN3/miR-205-5p interaction may serve a pivotal role in regulating breast cancer cellular proliferation under physiological conditions.
The "not so" Beautiful Game: a study on Brazilian players of the fantasy soccer game Cartola FC

Fantasy sports games exist for over 50 years and are popular in North America and in European countries. In Brazil, the sports fans only recently took interest in those games with Cartola FC, an online fantasy soccer game. This study aims to investigate the Brazilian players’ behavior and consumption in Cartola FC through a qualitative approach. Semi-structured interviews were conducted and the discussion was supported by Game Studies and consumer behavior theoretical approaches. The results pointed to the game boundaries’ permeability, where the actions performed by the players occur mainly outside of it. Although Cartola FC is an online game, the social ties with local friends and work colleagues are reinforced and, as in previous researches carried on in other countries, the act of playing deepened the players’ relationship with the sport. It was also found an expressive informal market of League betting, created to transgress the Brazilian legislation.
