Urban traffic situation information is the basis of effective traffic guidance and traffic control. In order to promote communication and practical applications of traffic information, then can provide full, accurate, real time and sufficient traffic information service to public, government and correlative enterprises, in this paper, the authors proposed the dynamic traffic information collection and processing methods of intelligent transportation systems (ITS) common information platform (CIP) based on floating car technology. According to the characteristics of the ITS CIP data collection, they were required large scale, accurate and dynamic data collecting. A complete set of dynamic traffic information processing methods based on floating car technology were studied, including road data storage by two queues, error data elimination by taximeter, map matching by region dividing method and boundary rectangle, and traffic condition calculation by circle queues and A* algorithm. The application of the methods in the ITS CIP of Guangzhou City proved that the methods were quite effective and valuable to be popularized.

<h3>Objective:</h3> Utilize augmented reality (AR) to create military specific scenarios that can be objectively quantified and used to facilitate the detection of and return-to-duty (RTD) following mild traumatic brain injury (mTBI). <h3>Background:</h3> Methods of detecting military mTBI are rooted in neuropsychological tests that measure a construct of executive or motor function. This approach does not lend itself to accurate detection or appropriate RTD. We have demonstrated the HoloLens 2 AR device provides accurate biomechanical data. Placing digital assets in a user’s real-world via AR technology creates an ecological environment to evaluate function. An AR Rifle qualification test (RQT) to evaluate dynamic movement, information processing, shooting performance and decision-making was developed. To evaluate performance in the context of a group or military unit, a room clearing assessment was created. <h3>Design/Methods:</h3> Data were gathered from 157 active-duty service members. The RQT was performed under single- and dual-task conditions. Five room clearing scenarios in which information processing and motor demands were manipulated were completed. Kinematic data from the HoloLens 2 provided biomechanical outcomes characterizing cognitive and motor performance. <h3>Results:</h3> Reaction time (RT) to firing and accuracy of target acquisition in the RQT did not differ between single- and dual-task conditions (<i>p&lt;0.05)</i>. Transition time from kneel to stand did not differ between conditions; however, dual-task sway path (41.2±17.5 cm) post-transition was increased compared to single-task (35.1±14.2 cm). There was a significant increase in processing time as the complexity of the room clearing scenarios increased. <h3>Conclusions:</h3> The objective quantification of information processing (RT) and motor (postural sway and movement time) function while performing ecological AR military tasks can enhance the detection of mTBI using objective functional metrics. The use of AR to deliver realistic digital experiences will facilitate appropriate RTD to ensure the safety of the service member and their unit. <b>Disclosure:</b> Mr. Kaya has nothing to disclose.

IntroductionFederal agencies are increasingly expected to adopt enterprise risk management (ERM). However, public sector adoption of ERM has typically focused on the economic efficiency of tax-financed activities based on control-based practices. This reflects an emphasis on quantifiable concerns that invariably directs attention to risk, that (by definition) relates to identifiable and measurable events, thereby downplaying uncertain and unknown aspects of public exposures. This is a potentially serious shortcoming as government entities often act as society's risk managers of last resort. When extreme events happen what were previously considered private matters can quickly turn into public obligations. Hence, there is a need for proactive assessments of the evolving public risk landscape to discern unpredictable-even unknowable-developments.MethodsThe article reviews recent empirical studies on public risk management practices, effects of digitalization in public sector institutions, current strategic management research, and insights uncovered from a recent study of risk management practices in federal agencies. On this basis, the article explains how the ability to generate value from ERM can be enhanced when it intertwines with local responsive initiatives and central strategic risk analyses. It can form a dynamic adaptive risk management process where insights from dispersed actors inform updated risk analyses based on local autonomy and open exchange of information. This approach builds on specific structural features embedded in culture-driven aspirations to generate collaborative solutions. Its functional mode is an interactive control system with open discussions across levels and functions in contrast to conventional diagnostic controls that monitor predetermined key performance indicators (KPIs) and key risk indicators (KRIs).FindingsBacked by theoretical rationales and empirical research evidence, it is found that applications of ERM frameworks can produce positive results but is unable to deal with a public risk landscape characterized by uncertain unpredictable conditions with potentially extreme outcome effects. It is shown how interactive exchange of fast local insights and slow integrated strategic risk analyses supported by digitized data processing can form a dynamic adaptive system that enable public sector institutions to deal with emergent high-scale exposures. It is explained how the requirement for conducive organizational structures and supportive values require a new strategic risk leadership approach, which is contrasted to observed practices in federal agencies that are constrained by prevailing public governance requirements.DiscussionThe need to deal with uncertainty and unknown conditions demands a cognitive shift in current thinking from a primary focus on risk to also appraise complexity and prepare for the unexpected where data-driven methods can uncover emergent exposures through dynamic information processing. This requires strategic risk leaders that recognize the significance of complex public exposures with many unknowns and a willingness to facilitate digitalized information processing rooted in a collaborative organizational climate. If handled properly, adoption of ERM in public risk management can consider emergent dimensions in complex public exposures applying interactive information processing as a dynamic adaptive risk management approach incorporating digitized methods to solicit collective intelligence for strategic risk updating.

We propose that the behavior of nonlinear media can be controlled dynamically through coevolutionary systems. In this study, a light-sensitive subexcitable Belousov-Zhabotinsky reaction is controlled using a heterogeneous cellular automaton. A checkerboard image comprising of varying light intensity cells is projected onto the surface of a catalyst-loaded gel resulting in rich spatiotemporal chemical wave behavior. The coevolved cellular automaton is shown to be able to either increase or decrease chemical activity through dynamic control of the light intensity within each cell in both simulated and real chemical systems. The approach is then extended to construct a number of simple logical functions.

The development of the Metaverse nowadays has sparked widespread emotions among researchers, and correspondingly, many technologies have been derived to improve the human's sense of reality in the Metaverse. Especially, Extended Reality (XR), as an indispensable and important technology and research direction in the study of the metaverse, aims to bring seamless transformation between the virtual world and the real-world immersion to the experiential world. However, the technology we currently lack is the ability to simultaneously separate, classify, and locate dynamic human sound information to enhance human sound perception in complex noise environments. This article proposes a framework that utilizes FCNN for separation, algebraic models for positioning to obtain estimated distances, and SVM for classification. The dataset is built to simulates distance-related changes with accurate ground truth labels. The results show that our method can effectively separate, separate, and locate mixed sound data, providing users with comprehensive information about the content, gender, and distance of the speaking object in complex sound environments, enhancing their immersive experience and perception ability. Our innovation lies in the combination of three audio processing technologies and the framework proposed may well inspire future work on related topics.

In-sensor processing of dynamic and static information of visual objects avoids exchanging redundant data between physically separated sensing and computing units, holding promise for computer vision hardware. To this end, gate-tunable photodetectors, if built in a highly scalable array form, would lend themselves to large-scale in-sensor visual processing because of their potential in volume production and hence, parallel operation. Here we present two scalable in-sensor visual processing arrays based on dual-gate silicon photodiodes, enabling parallelized event sensing and edge detection, respectively. Both arrays are built in CMOS compatible processes and operated with zero static power. Furthermore, their bipolar analog output captures the amplitude of event-driven light changes and the spatial convolution of optical power densities at the device level, a feature that helps boost their performance in classifying dynamic motions and static images. Capable of processing both temporal and spatial visual information, these retinomorphic arrays suggest a path towards large-scale in-sensor visual processing systems for high-throughput computer vision.

Objective: ADHD has been repeatedly linked to problems in social functioning. Although some theories assume that the emotion recognition deficits are explained by general attentional deficits, mounting evidence suggests that they may actually constitute a distinct impairment. However, it remains unclear whether the deficient processing affects specific emotional categories or may generalize to all basic emotions. The present study aims to investigate these questions by assessing the sensitivity to all six basic emotions in adults with ADHD. Method: The participants judged the emotion onset in animated morph clips displaying facial expressions that slowly changed from neutral to emotional. Results: ADHD participants exhibited an impaired recognition of sad and fearful facial expressions. Conclusion: The present findings indicate that ADHD is possibly associated with a specific deficit in the recognition of facial emotions signaling negative social feedback.

Nowadays mobile positioning devices, sensor technologies, machine learning methods and cloud computing allow an efficient collection, processing and analysis of dynamic position information (trajectories), which can be used for various applications. Currently, data owners (e.g. vehicle producers or service operators) are reluctant to share data due to data privacy rules or because of the risk of sharing information with competitors, which could jeopardize the data owner's competitive advantage. In this paper, we compare various state-of-the-art anomaly detection methods like one-class support vector machine, isolation forest and bidirectional generative adversarial networks towards the detection of abnormal vehicle trajectories at intersections solving one-class classification problem with unsupervised learning algorithms. The experiments show that the selected models allow to identify anomalies with 98%-99% accuracy for the centralized approach. However, data exists mostly fragmented in form of isolated islands throughout the whole industry. Thus, we focus on a general concept of collaborative learning which provides with an increasing number of partners more accurate anomaly detection models than local models of each partner without exchanging raw data, but only synchronizing model parameters. We propose a federated learning algorithm for an one-class support vector machine model towards the detection of anomalies. The federated collaborative approach allows to construct comparable accuracy with the centralized approach, reduces the local data labeling load and keeps individual data private.

Remarkable technological developments for efficient image recognition (i.e., image acquisition and image data processing) have been reported in the past decade. Such advances in imaging and image processing technologies have driven significant progress in mobile electronics and machine vision applications. In particular, for image acquisition devices, two types of natural eyes (i.e., chambered and compound eyes) have inspired the development of novel multifunctional imaging devices with unique optical geometries. For image data processing devices, novel computing devices based on memristor crossbar arrays, such as electronic synapses, have been developed. More recently, the integration of imaging and image processing devices in a single unit further enhances the system‐level efficiency. Herein, such recent advances in the bio‐inspired artificial vision and neuromorphic image processing devices, aimed at providing efficient image recognition, are reviewed. First, various imaging devices inspired by the structural and functional features of natural eyes are introduced. Second, artificial synapses and their operation principles are thoroughly discussed. Third, the neuromorphic vision sensor that integrates the imaging and image processing devices is reviewed. Finally, a brief summary and future outlook are presented.

Organic–inorganic and polymer-based non-volatile resistive switching memory devices have gained increasing attention because of their excellent data storage capacity, flexibility, low power consumption, durability and widely used in modern electronics. Among the materials, 2D layered nanomaterial and polymer nanocomposites have attracted increasing attention because they can easily be integrated into electronic and optoelectronic devices due to their easy fabrication process, high storage capacity and promising structural properties. Fabrication of bistable memory devices based on organic–inorganic nanohybrid with charge blocking materials and polymer nanocomposite has been broadly elucidated for their extraordinary material properties. Recent enhancement in flexible memory devices based on organic–inorganic semiconductor dispersed in ferroelectric blend polymer has been investigated thoroughly in this review paper. Recent advancement in 2D layered material, ferroelectric polymer and the development of non-volatile memristive devices is extensively explained to understand their importance in flexible devices. Outstanding memory characteristics such as current on/off ratio, Vset, Vreset retention time, endurance of nanohybrid embedded polymer nanocomposite are also discussed meticulously. Next-generation memristor devices based on 2D nanomaterial and ferroelectric polymer with high speed and high density for developing neuromorphic computing system have been demonstrated.

Objective. Schizophrenia (SCZ) is a severe mental disorder associated with persistent or recurrent psychosis, hallucinations, delusions, and thought disorders that affect approximately 26 million people worldwide, according to the World Health Organization. Several studies encompass machine learning (ML) and deep learning algorithms to automate the diagnosis of this mental disorder. Others study SCZ brain networks to get new insights into the dynamics of information processing in individuals suffering from the condition. In this paper, we offer a rigorous approach with ML and deep learning techniques for evaluating connectivity matrices and measures of complex networks to establish an automated diagnosis and comprehend the topology and dynamics of brain networks in SCZ individuals. Approach. For this purpose, we employed an functional magnetic resonance imaging (fMRI) and electroencephalogram (EEG) dataset. In addition, we combined EEG measures, i.e. Hjorth mobility and complexity, with complex network measurements to be analyzed in our model for the first time in the literature. Main results. When comparing the SCZ group to the control group, we found a high positive correlation between the left superior parietal lobe and the left motor cortex and a positive correlation between the left dorsal posterior cingulate cortex and the left primary motor. Regarding complex network measures, the diameter, which corresponds to the longest shortest path length in a network, may be regarded as a biomarker because it is the most crucial measure in different data modalities. Furthermore, the SCZ brain networks exhibit less segregation and a lower distribution of information. As a result, EEG measures outperformed complex networks in capturing the brain alterations associated with SCZ. Significance. Our model achieved an area under receiver operating characteristic curve (AUC) of 100% and an accuracy of 98.5% for the fMRI, an AUC of 95%, and an accuracy of 95.4% for the EEG data set. These are excellent classification results. Furthermore, we investigated the impact of specific brain connections and network measures on these results, which helped us better describe changes in the diseased brain.
