Detection And Recognition

Facial expressions are a vital way for humans to show their perceived emotions. It is convenient for detecting and recognizing expressions or micro-expressions by annotating a lot of data in deep learning. However, the study of video-based expressions or micro-expressions requires that coders have professional knowledge and be familiar with action unit (AU) coding, leading to considerable difficulties. This paper aims to alleviate this situation. We deconstruct facial muscle movements from the motor cortex and systematically sort out the relationship among facial muscles, AU, and emotion to make more people understand coding from the basic principles: We derived the relationship between AU and emotion based on a data-driven analysis of 5,000 images from the RAF-AU database, along with the experience of professional coders.We discussed the complex facial motor cortical network system that generates facial movement properties, detailing the facial nucleus and the motor system associated with facial expressions.The supporting physiological theory for AU labeling of emotions is obtained by adding facial muscle movements patterns.We present the detailed process of emotion labeling and the detection and recognition of AU.Based on the above research, the video's coding of spontaneous expressions and micro-expressions is concluded and prospected.

When individuals are presented with emotional facial expressions they spontaneously react with brief, distinct facial movements that ‘mimic’ the presented faces. While the effects of facial mimicry on emotional perception and social bonding have been well documented, the role of facial attractiveness on the elicitation of facial mimicry is unknown. We hypothesized that facial mimicry would increase with more attractive faces. Facial movements were recorded with electromyography upon presentation of averaged and original stimuli while ratings of attractiveness and intensity were obtained. In line with existing findings, emotionally congruent responses were observed in relevant facial muscle regions. Unexpectedly, the strength of observers’ facial mimicry responses decreased with more averaged faces, despite being rated perceptually as more attractive. These findings suggest that facial attractiveness moderates the degree of facial mimicry muscle movements elicited in observers. The relationship between averageness, attractiveness and mimicry is discussed in light of this counterintuitive finding.

The purpose of this study was to examine the effect of singers’ physical movement on observers’ perception of musical quality at varying levels of physical expressivity during a choral performance. In addition, the relationship between observers’ levels of formal music training and their perception of musical quality was of interest. All observers ( N = 164) viewed and rated a set of three video scenarios of a choral performance. Each scenario was designed to represent three levels of physical movement: minimal (minimal body and facial movement), moderate (moderate head and facial movement), and high level (full body and facial movement). Results indicated that differing levels of singers’ physical movement and facial expressions were strongly related to observers’ perception of the musical quality. However, when analyzing this effect by observers’ formal musical background, no significant relationship was found between ratings of the musical quality and physical movement among musically trained observers across all three conditions, suggesting that musically trained observers may be less influenced by their visual perception when evaluating a music performance.

ABSTRACTRevolutionary struggle in order to compete for the independence of Indonesia has been a source of inspiration Indonesian artists, including Bambang Soelarto who wrote drama Domba-domba Re- volusi (DDR). DDR studied drama is quite interesting because it tries to criticize the freedom fight- ers. This study aims to: first to know the theme and the problem plays DDR; second to determine the relationship of the socio - historical struggle in 1948 with the sociological elements of drama DDR themes and issues. This study uses sociological theory of art. The basic principles of the sociology of art is the fact that the creation of works of art influenced by the historical social conditions where the work was created. Research using content analysis of Krippendorf, the methods used to examine the symbolic phenomena with the aim to explore and express the observed phenomenon which is the content, meaning, and an essential element of the literary work. Based results of this research is that Bambang Soelarto as the author tries to capture di?erence between fighters during the struggle for the political aspirations for 1948 are expressed in a work of drama. Historical events inspired the creation of drama DDR. Soelarto want to respond to the political aspirations of the di?erence between historical figures and wanted to provide an assessment and outlook through DDR.Keywords: themes, drama, sociology of art, social historical ABSTRAKRevolusi perjuangan dalam rangka memperebutkan kemerdekaan Indonesia telah men- jadi sumber inspirasi para seniman Indonesia, termasuk Bambang Soelarto yang menulis drama Domba-domba Revolusi (DDR). Drama DDR cukup menarik diteliti karena mencoba mengkritisi para pejuang kemerdekaan. Penelitian ini bertujuan untuk: pertama, mengeta- hui tema dan permasalah drama DDR; kedua, mengetahui hubungan kondisi sosio-histo- ris perjuangan pada tahun 1948 dengan unsur-unsur sosiologis terimplisir pada unsur tema dan masalah drama DDR. Penelitian ini menggunakan teori sosiologi seni. Prinsip dasar dari sosiologi seni adalah adanya fakta bahwa penciptaan karya seni dipengaruhi oleh kon- disi sosial historis tempat karya itu diciptakan. Penelitian ini menggunakan metode con- tent analysis dari Krippendorf, yakni metode yang dipergunakan untuk meneliti fenome- na-fenomena simbolik dengan tujuan untuk menggali dan mengungkapkan fenomena yang teramati yang merupakan isi, makna, dan unsur esensial karya sastra. Berdasarkan hasil penelitian dapat diketahui bahwa Bambang Soelarto sebagai penulis mencoba un- tuk menangkap perbedaan antara pejuang aspirasi politik selama perjuangan tahun 1948 untuk diekspresikan dalam sebuah karya drama. Peristiwa sejarah mengilhami penciptaan drama DDR. Soelarto ingin menanggapi aspirasi politik perbedaan antara tokoh-tokoh se- jarah dan ingin memberikan penilaian dan pandangan pandangannnya melalui DDR.Kata kunci: tema, drama, sosiologi seni, sosial historis

Sufficient Oxygen

Hypoxia is a condition in which cells, tissues, or organisms are deprived of sufficient oxygen supply. Aerobic organisms have a hypoxic response system, represented by hypoxia-inducible factor 1-α (HIF1A), to adapt to this condition. Due to publication bias, there has been little focus on genes other than well-known signature hypoxia-inducible genes. Therefore, in this study, we performed a meta-analysis to identify novel hypoxia-inducible genes. We searched publicly available transcriptome databases to obtain hypoxia-related experimental data, retrieved the metadata, and manually curated it. We selected the genes that are differentially expressed by hypoxic stimulation, and evaluated their relevance in hypoxia by performing enrichment analyses. Next, we performed a bibliometric analysis using gene2pubmed data to examine genes that have not been well studied in relation to hypoxia. Gene2pubmed data provides information about the relationship between genes and publications. We calculated and evaluated the number of reports and similarity coefficients of each gene to HIF1A, which is a representative gene in hypoxia studies. In this data-driven study, we report that several genes that were not known to be associated with hypoxia, including the G protein-coupled receptor 146 gene, are upregulated by hypoxic stimulation.

AbstractIn the project I-CARE a technical system for tablet devices is developed that captures the personal needs and skills of people with dementia. The system provides activation content such as music videos, biographical photographs and quizzes on various topics of interest to people with dementia, their families and professional caregivers. To adapt the system, the activation content is adjusted to the daily condition of individual users. For this purpose, emotions are automatically detected through facial expressions, motion, and voice. The daily interactions of the users with the tablet devices are documented in log files which can be merged into an event list. In this paper, we propose an advanced format for event lists and a data analysis strategy. A transformation scheme is developed in order to obtain datasets with features and time series for popular methods of data mining. The proposed methods are applied to analysing the interactions of people with dementia with the I-CARE tablet device. We show how the new format of event lists and the innovative transformation scheme can be used to compress the stored data, to identify groups of users, and to model changes of user behaviour. As the I-CARE user studies are still ongoing, simulated benchmark log files are applied to illustrate the data mining strategy. We discuss possible solutions to challenges that appear in the context of I-CARE and that are relevant to a broad range of applications.

The Relationship

Deficiency in long-chain omega-3 polyunsaturated fatty acids, in particular eicosapentaenoic acid (EPA), is implicated in aggression and callous-unemotional (CU) traits. A violence inhibition mechanism (VIM) has been proposed to regulate aggression through responding to expressions of distress. However, it remains unclear whether EPA intake is related to the VIM, and if so, whether this pathway can mediate relationships between EPA intake and deviant personality traits. The current investigation documents two, independently-sampled studies that tested relationships between EPA intake, personality (aggression, CU traits), and electrophysiological indices of the VIM (motor extinction cued by facial expressions of distress). In study one, 98 participants completed a food-frequency questionnaire, the inventory of callous-unemotional traits, and an aggression questionnaire. EPA intake was negatively correlated with physical aggression, even after controlling for age and sex. In study two, 47 participants completed the same measures in addition to having electroencephalography recorded during a novel paradigm assessing the distinct processing stages of the VIM. Stop-P300 (motor extinction) responses to facial expressions of distress mediated the relationship between EPA intake and physical aggression. For the first time, we have evidenced an association between EPA intake and indices of distress-induced motor extinction proficiency. Findings are in line with a proposed role of EPA in regulating aggression, possibly through associations with networks involved in distress-cued executive control over behaviour. Results are discussed in terms of the potential benefit of nutritional supplementation in clinical and forensic arenas.

Age Perception

We form impressions of others by observing their constant and dynamically-shifting facial expressions during conversation and other daily life activities. However, conventional aging research has mainly considered the changing characteristics of the skin, such as wrinkles and age-spots, within very limited states of static faces. In order to elucidate the range of aging impressions that we make in daily life, it is necessary to consider the effects of facial movement. This study investigated the effects of facial movement on age impressions. An age perception test using Japanese women as face models was employed to verify the effects of the models’ age-dependent facial movements on age impression in 112 participants (all women, aged 20–49 years) as observers. Further, the observers’ gaze was analyzed to identify the facial areas of interests during age perception. The results showed that cheek movement affects age impressions, and that the impressions increase depending on the model’s age. These findings will facilitate the development of new means of provoking a more youthful impression by approaching anti-aging from a different viewpoint of facial movement.

Cross Fertilization

The relationship between “language change” and “language evolution” has recently become subject to some debate regarding the scope of both concepts. It has been claimed that while the latter used to refer to language origins in the first place, both terms can now, to a certain extent, be used synonymously. In this paper, I argue that this can partly be explained by parallel develop-ments both in historical linguistics and in the field of language evolution research that have led to a considerable amount of convergence between both fields. Both have adopted usage-based approaches and data-driven methods, which entails similar research questions and similar perspectives on the phenomena under investigation. This has ramifications for current models and theories of language change (or evolution). Two approaches in particular – the concept of com-plex adaptive systems and construction grammar – have been combined in integrated approaches that seek to explain both language emergence and language change over historical time. I discuss the potential and limitations of this integrated approach, and I argue that there is still some unex-plored potential for cross-fertilization.
