Résumé :

AbstractBlock polymer structure-directing agents (SDA) enable the production of porous nanoscale materials. Most strategies rely upon polymer equilibration where diverse morphologies are realized in porous functional materials. This review details how solvent selectivity determines the polymer SDA behaviors, spanning from bulk-type to solution-type. Equilibrating behavior of either type, however, obscures nanostructure cause-and-effect since the resulting sample series convolve multiple spatial variations. Solution-type SDA behaviors include both dynamic and persistent micelles. Persistent micelle templates (PMT) use high solvent selectivity for kinetic entrapment. PMTs enable independent wall thickness control with demonstrated 2 Å precision alterations. Unimodal PMT pore size distributions have spanned from 11.8 to 109 nm and multimodal pore sizes up to 290 nm. The PMT method is simple to validate with diffraction models and is feasible in any laboratory. Finally, recent energy device publications enabled by PMT are reviewed where tailored nanomaterials provide a unique perspective to unambiguously identify nanostructure–property–performance relationships.

Résumé :

This paper presents the use of our multimodal mixed reality telecommunication system to support remote acting rehearsal. The rehearsals involved two actors, located in London and Barcelona, and a director in another location in London. This triadic audiovisual telecommunication was performed in a spatial and multimodal collaborative mixed reality environment based on the “destination-visitor” paradigm, which we define and put into use. We detail our heterogeneous system architecture, which spans the three distributed and technologically asymmetric sites, and features a range of capture, display, and transmission technologies. The actors' and director's experience of rehearsing a scene via the system are then discussed, exploring successes and failures of this heterogeneous form of telecollaboration. Overall, the common spatial frame of reference presented by the system to all parties was highly conducive to theatrical acting and directing, allowing blocking, gross gesture, and unambiguous instruction to be issued. The relative inexpressivity of the actors' embodiments was identified as the central limitation of the telecommunication, meaning that moments relying on performing and reacting to consequential facial expression and subtle gesture were less successful.

Résumé :

The New Jersey Department of Transportation (NJDOT) updates its long-range transportation plan every 5 years. The plan sets forth strategies, provides a framework for directing investment, and identifies financial resources needed to sustain the plan’s vision. Setting the direction of a long-range transportation program revolves around forecasting future transportation conditions and managing investments to address future needs. An analysis tool was needed to help assess the impact of growth on the statewide transportation system and predict system performance based on multimodal strategic investments. The development and use of an analysis tool based on a travel demand model to assess congestion and mobility issues in 2025 are described. The analysis tool linked the state’s three metropolitan planning organization (MPO) regional travel demand models to perform a statewide assessment. Although the models were run independently, methods were developed to provide a common basis for forecasting future travel conditions. The models used MPO-generated trend-based growth in population and employment through 2025. Multimodal transportation supply and demand strategies, including transit improvements, capacity improvements, transportation demand management strategies, and intelligent transportation systems-transportation system management strategies, were simulated and tested to assess what types and combinations of improvements would be needed to relieve congestion and improve mobility. The tool proved very helpful in defining transportation needs and providing input to a financial assessment. The testing indicated that no single strategy is likely to improve future travel conditions, but a combination of multimodal strategies offers significant improvements over congestion levels predicted for 2025 if no improvements are made.

Résumé :

This research investigates the level modality of Sukin skincare product advertisement in social media through the descriptive qualitative method. Kress and Van Leeuwen propose the theories supporting this thesis. The primary data sources in this thesis were ten visual advertisements. The steps passed in this analysis are selecting ten visual images, identifying the visual elements of the ten advertisements, categorizing the visual elements into visual contact, social distance, perspectives, modality, and putting them in the table. The result of this thesis shows there are 5 of demand images, 15 of offer images, 12 of far social distance, 7 of close personal distance, 1 of close social distance, 8 of high modality, 2 of low modality, 20 of frontal angle, and 20 of eye level. Thus, it can be concluded that far social distance is dominant, indicating that the company intends to show truthfulness and credibility in convincing the viewer to try the products. It is also demonstrated that the multimodal visual element plays a pivotal role in directing the advertisement's message towards the audience

Résumé :

The lyrics of 10CC’s ‘I’m Not in Love’ revolve around a musical persona asserting that he is not in love and directing his addressee not to mistake his behaviour as indicating that he is in love with her. However, despite the negative assertions and imperatives, the feel of the song is that the musical persona is in fact in love. This article examines how the complex multimodal context of a song interacts with the prototypical pragmatic processing of negation to allow listeners to reach an interpretation of the song that contradicts the assertions made by the musical persona. The article outlines the nature of negation and examines the language and musical features that create a context of mixed messages that interferes with pragmatic processing.

Résumé :

Recent research on multimodal information processing has provided evidence for the existence of crossmodal links in spatial attention between vision, audition, and touch. The present study examined whether these links can be exploited to support attention allocation in workplaces that involve competing task demands and the potential for visual data overload. In particular, the effectiveness of tactile cues for guiding visual attention to the location of a critical event was tested in the context of an air traffic control simulation. Participants monitored a display depicting the flight paths of 40 aircraft and were presented with tactile cues indicating either just the occurrence, or both the occurrence and display location, of an event requiring a participant response. Tactile cuing, especially when combined with location information, resulted in significantly higher detection rates and faster response times to these events. These findings indicate that tactile cuing is a promising means of directing visual attention in a data-driven manner.

Résumé :

Background: Verbal Fluency (VF) tasks are known as multimodal measures clinically useful for monitoring cognitive decline during the aging process. Considering that the executive control observed along VF tasks calls for a set of functions directing the behavior toward a general goal, it may be assumed that there is a correspondence between VF ability and Functional Capacity (FC). Methods: With this assumption in mind, the author aimed at performing a literature research on VF ability and FC within aging. Results: Only four studies whose title/abstract presented the target key-terms, partially fulfilled the adopted criteria and were selected for discussion. Taken together, these articles attempted to correlate cognitive material to aspects of functionality, one of which not doing so directly with the elderly and another with no specific association with VF abilities. Conclusion: Theories suggest that VF might be associated with complex executive mechanisms. Still, a theoretical scheme and controlled researches possibly able to shed light on the underlying balance among the VF abilities and functionality within aging are as yet, unknown.

Résumé :

Thermal therapies such as radiofrequency ablation (RFA) are gaining widespread clinical adoption in the local treatment of skeletal metastases. RFA has been shown to successfully destroy tumor cells, yet the impact of RFA on the quality of the surrounding bone has not been well characterized. RFA treatment was performed on femora of rats with bone metastases (osteolytic and osteoblastic) and healthy age matched rats. Histopathology, second harmonic generation imaging and backscatter electron imaging were used to characterize changes in the structure, organic and mineral components of the bone after RFA. RFA treatment was shown to be effective in targeting tumor cells and promoting subsequent new bone formation without impacting the surrounding bone negatively. Mineralization profiles of metastatic models were significantly improved post-RFA treatment with respect to mineral content and homogeneity, suggesting a positive impact of RFA treatment on the quality of cancer involved bone. Evaluating the impact of RFA on bone quality is important in directing the growth of this minimally invasive therapeutic approach with respect to fracture risk assessment, patient selection, and multimodal treatment planning.

Résumé :

Event-related functional magnetic resonance imaging was used to identify brain areas involved in spatial attention and determine whether these operate unimodally or supramodally for vision and touch. On a trial-by-trial basis, a symbolic auditory cue indicated the most likely side for the subsequent target, thus directing covert attention to one side. A subsequent target appeared in vision or touch on the cued or uncued side. Invalidly cued trials (as compared with valid trials) activated the temporo-parietal junction and regions of inferior frontal cortex, regardless of target modality. These brain areas have been associated with multimodal spatial coding in physiological studies of the monkey brain and were linked to a change in the location that must be attended to in the present study. The intraparietal sulcus and superior frontal cortex were also activated in our task, again, regardless of target modality, but did not show any specificity for invalidly cued trials. These results identify a supramodal network for spatial attention and reveal differential activity for inferior circuits involving the temporo-parietal junction and inferior frontal cortex (specific to invalid trials) versus more superior intraparietal-frontal circuits (common to valid and invalid trials).

Résumé :

AbstractThe current study uses principles from Cognitive Grammar to better account for the symbolic integration of gesture and speech. Drawing on data collected from language use, we examine the use of two attention-directing strategies that are expressed through gesture, beats and pointing. It has been claimed that beats convey no semantic information. We propose that beat gestures are symbolic structures. It has also been noted that beats are often overlaid on other gestures. To date, however, no detailed explanation has been offered to account for the conceptual and phonological integration of beats with other co-expressed gestures. In this paper, we explore the integration of beats and pointing gestures as complex gestural expressions. We find that simple beat gestures, as well as beat gestures co-expressed with pointing gestures, are used to direct attention to meanings in speech that are associated with salient components of stancetaking acts. Our account further reveals a symbolic motivation for the apparent “superimposing” of beats onto pointing gestures. By closely examining actual usage events, we take an initial step toward demonstrating how the symbolic elements of both beats and points are integrated in multimodal constructions.

Résumé :

In recent years, companies have been seeking communication skills from their employees. Increasingly more companies have adopted group discussions during their recruitment process to evaluate the applicants’ communication skills. However, the opportunity to improve communication skills in group discussions is limited because of the lack of partners. To solve this issue as a long-term goal, the aim of this study is to build an autonomous robot that can participate in group discussions, so that its users can repeatedly practice with it. This robot, therefore, has to perform humanlike behaviors with which the users can interact. In this study, the focus was on the generation of two of these behaviors regarding the head of the robot. One is directing its attention to either of the following targets: the other participants or the materials placed on the table. The second is to determine the timings of the robot’s nods. These generation models are considered in three situations: when the robot is speaking, when the robot is listening, and when no participant including the robot is speaking. The research question is: whether these behaviors can be generated end-to-end from and only from the features of peer participants. This work is based on a data corpus containing 2.5 h of the discussion sessions of 10 four-person groups. Multimodal features, including the attention of other participants, voice prosody, head movements, and speech turns extracted from the corpus, were used to train support vector machine models for the generation of the two behaviors. The performances of the generation models of attentional focus were in an F-measure range between 0.4 and 0.6. The nodding model had an accuracy of approximately 0.65. Both experiments were conducted in the setting of leave-one-subject-out cross validation. To measure the perceived naturalness of the generated behaviors, a subject experiment was conducted. In the experiment, the proposed models were compared. They were based on a data-driven method with two baselines: (1) a simple statistical model based on behavior frequency and (2) raw experimental data. The evaluation was based on the observation of video clips, in which one of the subjects was replaced by a robot performing head movements in the above-mentioned three conditions. The experimental results showed that there was no significant difference from original human behaviors in the data corpus and proved the effectiveness of the proposed models.

Résumé :

Previous ERP studies have uncovered cross-modal interactions in endogenous spatial attention. Directing attention to one side to judge stimuli from one particular modality can modulate early modality-specific ERP components not only for that modality, but also for other currently irrelevant modalities. However, past studies could not determine whether the spatial focus of attention in the task-irrelevant secondary modality was similar to the primary modality, or was instead diffuse across one hemifield. Here, auditory or visual stimuli could appear at any one of four locations (two on each side). In different blocks, subjects judged stimuli at only one of these four locations, for an auditory (Experiment 1) or visual (Experiment 2) task. Early attentional modulations of visual and auditory ERPs were found for stimuli at the currently relevant location, compared with those at the irrelevant location within the same hemifield, thus demonstrating within-hemifield tuning of spatial attention. Crucially, this was found not only for the currently relevant modality, but also for the currently irrelevant modality. Moreover, these within-hemifield attention effects were statistically equivalent regardless of the task relevance of the modality, for both the auditory and visual ERP data. These results demonstrate that within-hemifield spatial attention for one task-relevant modality can transfer cross-modally to a task-irrelevant modality, consistent with spatial selection at a multimodal level of representation.

Background Management of ADHD requires multimodal treatments. Parental participation is one of the most important factors for effective ADHD treatment.Objective To investigate the effectiveness of behavioral parent training combined with routine clinical care, in reducing ADHD symptoms in children.Methods Quantitative and qualitative methods were combined in this study. This study was conducted at 3 growth and developmental clinics in Central of Java, on June-July 2016. The quantitative aspect was assessed by comparing ADHD quotient scores at pre- and post-intervention, while the qualitative aspect by intensive parental interviews. Parents of children with ADHD were randomized with block random sampling. In the treatment group, parents received behavioral training for 7 weeks, along with weekly routine clinical care for their children. The control group received only routine clinical care of the children. Six parents in the treatment group were randomly selected for intensive interviews.Results A total of 67 parents with their children were involved. Both groups’ ADHD quotient scores improved post-intervention. The treatment group ADHD quotient score was reduced from 120.53 to 116.41 (effect size Cohen’s d 0.68). The control group ADHD quotient score was reduced from 121.74 to 119.83 (effect size Cohen’s d 0.23). Mean difference post-intervention in both group was not significant (p=.161). After behavioral parent training, communication between parents and children increased and parents’ capability in directing their children’s daily activity increased.Conclusion Behavioral parent training can not enhacing effectiveness of routine clinical care to reduce ADHD symptoms in children.

Résumé :

Abstract Modern burns surgery is multidisciplinary, multimodal and includes a dermal preservation approach. The management of the surgical wound starts in the pre-hospital environment with stabilization and assessment of the burn injured patient according to protocols of trauma resuscitation with special emphasis in the assessment of the burn depth and surface area. A large burn requires fluid resuscitation and physiological support, including counterbalancing hyper metabolism, fighting infection and starting a long burns intensive care journey. A deep burn may impose the need for surgical debridement and cover through a staged approach of excision of devitalized tissue depending on its extension and patient circumstances. These methodologies warrant patients survivability and require professionals integrated in a multidisciplinary team sharing decisions and directing management. Burns Multimodality involves multiple techniques used according to patient’s needs, wound environment, operators experience and available resources. Traditional practices used together with new techniques may reduce morbidity and operative time but also challenge stablished practice. The concept of using the best teams with the best techniques combines with the need for selective and judicious surgery that preserves tissue architecture and spares as much as possible dermal component, therefore reducing the possibility of functional impairment and cosmetic embarrassment caused by pathological scars. Who is best placed to perform these tasks, the appropriate or best timing of surgery and the different practices used to achieve best results will be discussed, together with a reflection on what the future holds for these fundamental steps in the management of the burn injured patient turning into a functional burn survivor.

Résumé :

Multimodal analysis examines how different modes, such as space, gesture, and language, instantiate meaning together. In this paper, a Systemic Functional-Multimodal Discourse Analysis demonstrates how teachers enact their pedagogy with their students across modes through what is represented experientially, how relationships between people are construed interpersonally, and how coherent texts are realized textually. This paper is a preliminary study of classroom data from a larger project looking at the multimodal pedagogy of Japanese secondary school teachers of English through the paired lenses of Systemic Functional-Multimodal Discourse Analysis and Legitimation Code Theory. It demonstrates how methods from these perspectives may be productively combined. How this teacher builds cumulative knowledge multimodally can be uncovered through the analysis of pedagogic register (Rose, 2018) and exchange (Berry, 1981; Martin and Rose, 2007), as well as classroom space and representing and textual action (Amundrud, 2017; Martin and Zappavigna, 2019). How both gesture and dialogic exchange between the teacher and students modulate the contextual relation of the knowledge construed in class is also explored via semantic gravity, which looks at how closely connected knowledge practices are to their context (Maton, 2014). As a preliminary study, the paper closes with limitations and future directions for this pedagogic multimodality research.

Résumé :

Trip generation estimates are integral to assessing the transport impacts of land use developments. However, past efforts have predominantly focused on vehicle trips only. This paper provides an international literature review of multimodal trip generation associated with land use developments. A total of 153 publications were sourced as relevant to the review. The results show that although multimodal trip generation studies have been relatively scant, they have received greater attention in the last 10 years. A range of issues was identified with estimating and applying multimodal trip generation rates, not least was a lack of sufficient data and higher complexity in data collection compared with vehicle trip generation studies. Current knowledge gaps highlight opportunities to move toward greater international coordination and sharing of multimodal trip generation data, along with exploring the use of technology to assist with data collection. Key directions for the future include a fundamental change in paradigm to consistently account for multimodal trip generation, the development of an international multimodal trip generation database, and greater sensitivity testing in assessing the multimodal impacts of new land use developments.

Résumé :

Managing classroom activities in children has become a challenge for English as a Foreign Language (EFL) teachers. Teachers usually use gestures in class activities, such as giving directions and pointing at students. This study explores the multimodal representation of the teacher's gestures when managing classroom activities in the EYL context. Data were collected through non-participant observation and analyzed by Systemic Functional Multimodal Discourse Analysis (SFMDA). The findings show that four meanings are multimodally represented in teacher gestures, namely (1) building student-teacher relationships through clapping and thumbs up, (2) emphasizing instruction through raising hands, pointing and lifting class objects, (3) encouraging involvement of students in academic tasks through finger pointing and counting down, and (4) warning of disruptive behavior of students through pulling gestures. Pedagogically, this research provides a paradigm shift that classroom-based communication does not have to use a single semiotic source but also a combination of other semiotic sources to help students understand teacher instructions easily.

Résumé :

Molecular imaging has emerged at the end of the last century as an interdisciplinary method involvingin vivoimaging and molecular biology aiming at identifying living biological processes at a cellular and molecular level in a noninvasive manner. It has a profound role in determining disease changes and facilitating drug research and development, thus creating new medical modalities to monitor human health. At present, a variety of different molecular imaging techniques have their advantages, disadvantages, and limitations. In order to overcome these shortcomings, researchers combine two or more detection techniques to create a new imaging mode, such as multimodal molecular imaging, to obtain a better result and more information regarding monitoring, diagnosis, and treatment. In this review, we first describe the classic molecular imaging technology and its key advantages, and then, we offer some of the latest multimodal molecular imaging modes. Finally, we summarize the great challenges, the future development, and the great potential in this field.

Résumé :

Photoacoustic ophthalmoscopy (PAOM) is a novel, hybrid, non-ionizing, and non-invasive imaging technology that has been used to assess the retina. PAOM can provide both anatomic and functional retinal characterizations with high resolution, high sensitivity, high contrast, and a high depth of penetration. Thus, ocular diseases can be precisely detected and visualized at earlier stages, resulting in an improved understanding of pathophysiology, improved management, and the improved monitoring of retinal treatment to prevent vision loss. To better visualize ocular components such as retinal vessels, choroidal vessels, choroidal neovascularization, retinal neovascularization, and the retinal pigment epithelium, an advanced multimodal ocular imaging platform has been developed by a combination of PAOM with other optical imaging techniques such as optical coherence tomography (OCT), scanning laser ophthalmoscopy (SLO), and fluorescence microscopy. The multimodal images can be acquired from a single imaging system and co-registered on the same image plane, enabling an improved evaluation of disease. In this review, the potential application of photoacoustic ophthalmoscopy in both research and clinical diagnosis are discussed as a medical screening technique for the visualization of various ocular diseases. The basic principle and requirements of photoacoustic ocular imaging are introduced. Then, various photoacoustic microscopy imaging systems of the retina in animals are presented. Finally, the future development of PAOM and multimodal imaging is discussed.

Résumé :

Multimodal transportation is an important component of the transport system. The development of multimodal transportation requires coordination of various modes of transport and their integration into a single organizational system that operates on the basis of the formation of logistics centers. The article considers the problem of forming an ecosystem of multimodal transportation in Ukraine, reveals the peculiarities of its taxation and interaction in the digital economy. The existing regulatory and legal support of logistic activities in Ukraine is also analyzed. At present, multimodal transportation is of great importance for the economy of Ukraine. This is one of the important innovative directions in the development of the transport system at both the national and the international levels. Despite the fact that this direction is actively developing, today there is no clear legal and contractual support for this institution. The article analyzes the role of tax regulation of multimodal transportation along with the risks of environmental burden. It is noted that in Ukraine, amendments to the legislation in the field of regulation of multimodal transportation are extremely important, as well as the need to adopt a separate law that would allow to develop modern methods of cargo delivery, improve the quality of service for consumers of transport services, and reduce transportation costs. Among the main reasons that hinder the development of mixed transportation are the following: imperfection of the regulatory and legal settlement of multimodal transportation issues and the disparity between the levels of development of the capacity of ports for processing goods and railway infrastructure. The prospect of further research is the development of a theoretical and methodological approach to the choice of strategies and instruments for the development of transport infrastructure and tax regulation of multimodal transportation.

This research was conducted to explore the value of multimodal magnetic resonance imaging (MRI) based on the alternating direction algorithm in the diagnosis of early cervical cancer. 64 patients diagnosed with early cervical cancer clinicopathologically were included, and according to the examination methods, they were divided into A group with conventional multimodal MRI examination and B group with the multimodal MRI examination under the alternating direction algorithm. The diagnostic results of two types of multimodal MRI for early cervical cancer staging were compared with the results of clinicopathological examination to judge the application value in the early diagnosis of cervical cancer. The results showed that in the 6 randomly selected samples of early cervical cancer patients, the peak signal-to-noise ratio (PSNR) and structural similarity image measurement (SSIM) of multimodal MRI images under the alternating direction algorithm were significantly higher than those of conventional multimodal MRI images and the image reconstruction was clearer under this algorithm. By comparing MRI multimodal staging, statistical analysis showed that the staging accuracy of B group was 75%, while that of A group was only 59.38%. For the results of postoperative medical examinations, the examination consistency of B group was better than that of A group, with a statistically significant difference ( P < 0.05). The area under the receiver operating characteristic (ROC) curve (AUC) of B group was larger than that of A group; thus, sensitivity was improved and misdiagnosis was reduced significantly. Multimodal MRI under the alternating direction algorithm was superior to conventional multimodal MRI examination in the diagnosis of early cervical cancer, as the lesions were displayed more clearly, which was conducive to the detection rate of small lesions and the staging accuracy. Therefore, it could be used as an ideal MRI method for the assistant diagnosis of cervical cancer staging.

Résumé :

Computational thinking (CT) is in the midst of an ongoing debate about its scope and definitions. There is a trend away from a “traditional” computer science-inspired agenda towards a focus on universal competences for today’s labor market. However—and this is the motivation behind the research—the shift described is just an unconscious attempt to reveal the immanent nature of CT as an evolving semiotic phenomenon. The aim of this study is to explore directions and perspectives for the further development of CT and related methodological design approaches. As a research strategy, this article utilizes a case study on the presented set of resources dedicated to CT early education and reveals it in terms of multimodal discourse analysis. As a result, a landscape of future CT trends is presented, uncovering CT from a multimodal semiotic perspective. This article discusses various issues related to CT and its multimodal semiotics nature, perspectives on the design of CT-related resources and additional educational issues such as the perspectives on instructional approaches for CT teaching. We conclude that CT as a social phenomenon is in the process of an evolutionary transformation of its constitutive structure in the direction of further revealing its agentive semiotic nature.

Résumé :

Diagnosis of complex engineering systems requires the use of multiple sensor sources to acquire information. In this paper we present a survey of multimodal data acquisition systems for nondestructive testing (NDT) and engineering analysis. We begin with a summary of the relative strengths and weaknesses of individual NDT modalities. Thereafter we present existing multimodal inspection hardware systems that use complementary NDT sensors. The advantages of such multimodal data acquisition over conventional single modality sensors in inspection and analysis are highlighted. Possible approaches to fuse complementary multimodal sensor data are discussed. We conclude with possible directions for the future development of multimodal inspection systems.

Résumé :

Maps have been used to facilitate travellers in wayfinding and they are normally read at different orientations. A multimodal map has been introduced to enable blind people to learn maps. However, such maps usually enable them to explore maps in a fixed orientation. The effect of exploring maps in such way on user cognitive maps and sense of directions is unknown. Therefore, this paper investigates the effect on blind people’s cognitive maps and their sense of directions. Results showed that in the rotatable condition, some blind people have the ability to build accurate cognitive maps of the tested maps as accurate as in the static condition. Blind people were found able to point to the direction accurately in the rotatable condition than in the static condition. This was supported by their scores when reconstructing maps. However, there were no correlations found between user sense of directions and their pointing accuracy.

Résumé :

Multimodal fusion is one of the popular research directions of multimodal research, and it is also an emerging research field of artificial intelligence. Multimodal fusion is aimed at taking advantage of the complementarity of heterogeneous data and providing reliable classification for the model. Multimodal data fusion is to transform data from multiple single-mode representations to a compact multimodal representation. In previous multimodal data fusion studies, most of the research in this field used multimodal representations of tensors. As the input is converted into a tensor, the dimensions and computational complexity increase exponentially. In this paper, we propose a low-rank tensor multimodal fusion method with an attention mechanism, which improves efficiency and reduces computational complexity. We evaluate our model through three multimodal fusion tasks, which are based on a public data set: CMU-MOSI, IEMOCAP, and POM. Our model achieves a good performance while flexibly capturing the global and local connections. Compared with other multimodal fusions represented by tensors, experiments show that our model can achieve better results steadily under a series of attention mechanisms.

Résumé :

With the continuous development of portable noninvasive human sensor technologies such as brain–computer interfaces (BCI), multimodal emotion recognition has attracted increasing attention in the area of affective computing. This paper primarily discusses the progress of research into multimodal emotion recognition based on BCI and reviews three types of multimodal affective BCI (aBCI): aBCI based on a combination of behavior and brain signals, aBCI based on various hybrid neurophysiology modalities and aBCI based on heterogeneous sensory stimuli. For each type of aBCI, we further review several representative multimodal aBCI systems, including their design principles, paradigms, algorithms, experimental results and corresponding advantages. Finally, we identify several important issues and research directions for multimodal emotion recognition based on BCI.

Résumé :

Abstract The article analyzes the dynamics and structure of freight transport in Ukraine. It is established that container transportation in Ukraine occupies a small share in the total volume of cargo transportation compared to EU countries. In order to optimize the realization of trade, economic and transit potential of the country, multimodal schemes of cargo transportation are considered. One of the key issues in ensuring the sustainable development of the country’s transport system is to reduce emissions of CO2 and other pollutants. To achieve a set of environmental goals in Ukraine, it is necessary to intensify the formation of a sustainable transport system based on the development of multimodal container transportation with the involvement of “clean” modes of transport, primarily rail. Conceptual requirements for the formation of an environmentally sustainable system of multimodal container transportation in Ukraine are determined. Based on the calculations of the scenario, it was proved that the development of container rail transportation allows to obtain environmental and economic effects as a result of reducing CO2 emissions.

Résumé :

Multimodal sensory integration facilitates the generation of a unified and coherent perception of the environment. It is now well established that unimodal sensory perceptions, such as vision, are improved in multisensory contexts. Whereas multimodal integration is primarily performed by dedicated multisensory brain regions such as the association cortices or the superior colliculus, recent studies have shown that multisensory interactions also occur in primary sensory cortices. In particular, sounds were shown to modulate the responses of neurons located in layers 2/3 (L2/3) of the mouse primary visual cortex (V1). Yet, the net effect of sound modulation at the V1 population level remained unclear. In the present study, we performed two-photon calcium imaging in awake mice to compare the representation of the orientation and the direction of drifting gratings by V1 L2/3 neurons in unimodal (visual only) or multimodal (audiovisual) conditions. We found that sound modulation depended on the tuning properties (orientation and direction selectivity) and response amplitudes of V1 L2/3 neurons. Sounds potentiated the responses of neurons that were highly tuned to the cue’s orientation and direction but weakly active in the unimodal context, following the principle of inverse effectiveness of multimodal integration. Moreover, sound suppressed the responses of neurons untuned for the orientation and/or the direction of the visual cue. Altogether, sound modulation improved the representation of the orientation and direction of the visual stimulus in V1 L2/3. Namely, visual stimuli presented with auditory stimuli recruited a neuronal population better tuned to the visual stimulus orientation and direction than when presented alone. NEW & NOTEWORTHY The primary visual cortex (V1) receives direct inputs from the primary auditory cortex. Yet, the impact of sounds on visual processing in V1 remains controverted. We show that the modulation by pure tones of V1 visual responses depends on the orientation selectivity, direction selectivity, and response amplitudes of V1 neurons. Hence, audiovisual stimuli recruit a population of V1 neurons better tuned to the orientation and direction of the visual stimulus than unimodal visual stimuli.

The aim of this paper is to provide a comprehensive narrative review of extant scientific knowledge on the effectiveness of performance-enhancement-based interventions in youth sport settings. Specifically, the authors explore the effects of psychological interventions on the sport performance of young athletes (18 yr of age or under). Drawing on over 80 published studies that have attempted to enhance young athletes’ performances using a range of methodological and strategic approaches, four main clusters of research are presented. These clusters include single-strategy psychological-skills-training (PST) interventions, multimodal PST interventions, alternative single-strategy interventions, and alternative multimodal interventions. In each of these clusters, the landscape of work is overviewed and papers of particular methodological interest are highlighted before the authors draw out critical reflections, future research directions, and recommendations for supporting further scholarship and practice with young athletes.

Résumé :

Multimodal sentiment analysis and emotion recognition represent a major research direction in natural language processing (NLP). With the rapid development of online media, people often express their emotions on a topic in the form of video, and the signals it transmits are multimodal, including language, visual, and audio. Therefore, the traditional unimodal sentiment analysis method is no longer applicable, which requires the establishment of a fusion model of multimodal information to obtain sentiment understanding. In previous studies, scholars used the feature vector cascade method when fusing multimodal data at each time step in the middle layer. This method puts each modal information in the same position and does not distinguish between strong modal information and weak modal information among multiple modalities. At the same time, this method does not pay attention to the embedding characteristics of multimodal signals across the time dimension. In response to the above problems, this paper proposes a new method and model for processing multimodal signals, which takes into account the delay and hysteresis characteristics of multimodal signals across the time dimension. The purpose is to obtain a multimodal fusion feature emotion analysis representation. We evaluate our method on the multimodal sentiment analysis benchmark dataset CMU Multimodal Opinion Sentiment and Emotion Intensity Corpus (CMU-MOSEI). We compare our proposed method with the state-of-the-art model and show excellent results.

Résumé :

The rapid development of the internet and multimedia technology in recent years has continued to push foreign language education in the direction of modern education. Multimodal education is becoming more and more important in the field of English education as an advanced educational concept in the field of language education. As a result, many English teachers have begun to emphasize the use of multimodal teaching theory in their classrooms. This paper investigates a multimodal model that incorporates text and image features, based on multimodal discourse theory, systemic functional linguistics theory, and foreign language teaching theory. This paper develops a multimodal model that can search for images and texts from various perspectives. We use an image feature bias term in the log-bilinear natural language model to influence the probability of predicting the next word based on the context, resulting in a multimodal model. The experimental results show that the proposed model, as an image-text relationship evaluation index system, has a slower search speed than other models but better search accuracy.

Résumé :

This article reviews 26 empirical studies on digital multimodal composing (DMC) published in well-established journals between 2010 and 2020. It provides a holistic overview of these studies in terms of context and participants, multimodal tasks, technology, and research data. Research strands and themes are also identified. This review shows that most studies on DMC were conducted in tertiary ESL/EFL contexts. The research was informed by various theoretical/pedagogical frameworks across multiple disciplines. The multimodal writing tasks included digital storytelling, digital video production, and multimodal presentation. Data were analyzed to address three main strands: 1) L2 students' DMC process, 2) students' perceptions of DMC, and 3) effects of DMC. Of note, DMC practices were reported to have benefited L2 students, such as enhancing audience and genre awareness, learner autonomy, language learning investment, identity development, multimodal communicative competence, and L2 competence. This article ends with pedagogical recommendations and directions for future research.

Résumé :

The article is aimed at defining the key difference between multimodal and intermodal transportations, as well as studying the role of transport operators in the organization of multimodal transportations. In the course of the study, it was identified that both in the scientific field and in practice, mixed transportation is often understood as synonymous with the concept of «multimodal transportation», but it is determined that all integrated (multimodal, intermodal, combined) and separate (segment) transportations are part of mixed ones, which complement each other. It is noted that multimodal and intermodal transportations have a certain difference between themselves, which consists in the presence of the number of contracts and the responsibility borne by the transportation operator. It is proposed to take into account all the conditions that cause influence on the result of the decision on the implementation of multimodal transportation. In the study of theoretical and practical aspects it was possible to allocate the operators of multimodal transportation as follows: operators who operate with sea vessels; operators who do not operate with sea vessels, but may own other rolling stock, warehouses, etc.; forwarders who are not always multimodal operators and can be agents of some part of a transportation and cooperate with the main operator. Their special role in the organization of multimodal transportation is substantiated, taking into account all the factors and elements that must closely interact with each other in the delivery process. Prospects for further research in this direction are the construction of an algorithm for choosing a multimodal operator, taking into account various conditions.

Résumé :

Multimodal images refer to images obtained by different sensors, and there are serious nonlinear radiation differences (NRDs) between multimodal images for photos of the same object. Traditional multimodal image matching methods cannot achieve satisfactory results in most cases. In order to better solve the NRD in multimodal image matching, as well as the rotation and scale problems, we propose a two-step matching method based on co-occurrence scale space combined with the second-order Gaussian steerable filter (G-CoFTM). We first use the second-order Gaussian steerable filter and co-occurrence filter to construct the image’s scale space to preserve the image’s edge and detail features. Secondly, we use the second-order gradient direction to calculate the images’ principal direction, and describe the images’ feature points through improved GLOH descriptors. Finally, after obtaining the rough matching results, the optimized 3DPC descriptors are used for template matching to complete the fine matching of the images. We validate our proposed G-CoFTM method on eight different types of multimodal datasets and compare it with five state-of-the-art methods: PSO-SIFT, CoFSM, RIFT, HAPCG, and LPSO. Experimental results show that our proposed method has obvious advantages in matching success rate (SR) and the number of correct matches (NCM). On eight different types of datasets, compared with CoFSM, RIFT, HAPCG, and LPSO, the mean SRs of G-CoFSM are 17.5%, 6.187%, 30.462%, and 32.21%, respectively, and the mean NCMs are 5.322, 11.503, 8.607, and 16.429 times those of the above four methods.
