Introduction: Taking into account the influence of the psycho-emotional sphere and its disorders on the pathogenetic mechanisms of rosacea, a comparative assessment of the clinical efficacy of a standard therapy and the complex therapy using Cortexin in papulopustular rosacea patients with moderate severity and concomitant neurological pathology was performed. The therapy influence on changes in the patients’ psycho-emotional state was also studied.
 Materials and methods: The study involved 216 papulopustular rosacea outpatients with moderate severity with a concomitant neurological pathology, aged 20 to 60 years. The patients were divided into 2 groups: 109 people (37 men and 72 women) in the study group, and 107 people (37 men and 70 women) in the control. All the patients received a treatment according to the ”Standard of Medical Care for Patients with Rosacea” of the Ministry of Health of the Russian Federation. The study group patients additionally received Cortexin. The study was carried out using the Zung Self-Rating Anxiety Scale (SAS), the Taylor Manifest Anxiety Scale, the Spielberger State-Trait Anxiety Inventory, and the Eysenck Personality Questionnaire.
 Results and discussion: The patients showed an increase in somatic manifestations of anxiety, levels of trait and state anxiety, and neuroticism initially before the start of treatment. The inclusion of Cortexin in the rosacea treatment re­duced the somatic manifestations of anxiety more effectively than standard therapy against the background of a more considerable decrease in proportion of patients with its moderate and high levels. The severity of trait and stateanxiety, neuroticism was also significantly lower against the background of the Cortexin use than with the standard treatment.
 Conclusion: The Cortexin inclusion in the rosacea pharmacotherapy against the background of a concomitant neu­rological pathology contributes to a more pronounced correction of psychophysiological parameters, reflecting the neuroticism levels, trait and state anxiety, and somatic manifestations of anxiety, compared to standard treatment.

A structured gambling interview schedule, the Eysenck Personality Questionnaire, Spielberger's State-Trait Anxiety Inventory, Zuckerman's Sensation Seeking Scale and Beck Depression Inventory were administered to 63 out of 120 pathological gamblers who had 5 years previously completed a behavioural treatment for uncontrollable gambling behaviour. Results indicated that both abstinence and controlled gambling outcomes were associated with continued improvement in self-report and psychological indices of social functioning and psychopathology. Response to treatment was associated with a reduction in arousal levels, anxiety and depression. Uncontrolled gamblers failed to show post-treatment changes on parameters of improvement. It was concluded that abstinence is not the only possible therapeutic outcome in behavioural treatment and further, that controlled gambling is not a temporary response which is followed by a return to continued uncontrollable gambling.

Vision-based perception systems are widely used in unmanned platforms and have an important role in tasks such as object classification, object detection, and instance segmentation. The function and performance of visual perception system is not only related to the sensing hardware and recognition algorithm, but also influenced by the external environment. In this paper, the detection performance of the artificial intelligence model is used as a metric to study the impact of vibration-blurred images on the environmental adaptability of visual perception system. The structure and function of AI-baesd visual perception system are analyzed, and two vibration-blurred image generation methods, vibration test and vibration simulation, are introduced. The experiment quantitatively verified the effect of mechanical vibration stress on the performance of AI model during the operation of visual perception system.

Robustness of visual perception system in progressive challenging weather scenarios

Color-based indexing is an important tool in image database retrieval. Compared with other features of the image, color features are less sensitive to noise and background complication. Based on the human visual system's perception of color information, this paper presents a dependent scalar quantization approach to extract the characteristic colors of an image as color features. The characteristic colors are suitably arranged in order to obtain a sequence of feature vectors. Using this sequence of feature vectors, a dynamic matching method is then employed to match the query image with database images for a nonstationary identification environment. The empirical results show that the characteristic colors are reliable color features for image database retrieval. In addition, the proposed matching method has acceptable accuracy of image retrieval compared with existing methods.

Visual perception, as a core component of Intelligent Transportation Systems (ITS), plays a key role in enhancing safety and efficiency in urban mobility. While single-task visual perception methods have applications in areas like pedestrian detection and traffic sign recognition, the complexity of real-world scenarios necessitates a shift toward multi-task approaches. This paper introduces the Edge-assisted Multi-task Visual Perception (EMVP) system, which is specifically designed to address the computational intensity and dynamic concurrency challenges inherent to multi-task processing in edge environments. EMVP adopts a collaborative architecture that strategically partitions computational tasks between vehicles and Road-Side Units (RSUs). By integrating Convolutional Neural Networks (CNNs) and Vision Transformers (ViTs), the system achieves a lightweight yet efficient multi-task model for resource-constrained environments. To adapt to the dynamic and concurrent nature of multi-vehicle scenarios, EMVP incorporates a content-aware adaptive inference mechanism based on reinforcement learning, enabling dynamic task scheduling to improve Quality of Service (QoS). Experimental results demonstrate that, compared to the single-task baseline model, the multi-task model of EMVP reduces the computational cost by 86.59% on average while achieving a 4.32% improvement in accuracy. Additionally, in dynamic multi-access environments, EMVP’s adaptive scheduling mechanism, which leverages spatiotemporal content awareness, achieves an average QoS improvement of 7.36% over the sub-optimal method.

Common research in the field of Virtual Reality (VR) considers acoustic stimulation as a highly important necessity for enhanced immersion into virtual scenes. However, most common VR toolkits do only marginally support the integration of sound for the application programmer. Furthermore, the quality of stimulation that is provided usually ranges from system sounds (e.g. beeps while selecting a menu) to simple 3D panning. In the latter case, these approaches do only allow the user to correctly detect sounds that are at quite a distance from his current position. Binaural synthesis is an interesting way to allow the spatial auditory representation by using few loudspeakers or headphones. This paper describes a system that combines the efforts of creating a binaural representation for the listener who is interacting in a common visual VR application in real-time, thus allowing the research on interaction between visual and auditory human perception systems. It will describe the theoretical background to establishing a binaural representation of a sound and the necessary hardware set-up for this. Afterwards, the infrastructure and software interface which will allow the connection of the audio renderer to a visual VR toolkit is discusse

The visual, vestibular, and haptic perceptual systems are each able to detect self-motion. Such information can be integrated during locomotion to perceive traversed distances. The process of distance integration is referred to as odometry. Visual odometry relies on information in optic flow patterns. For haptic odometry, such information is associated with leg movement patterns. Recently, it has been shown that haptic odometry is differently calibrated for different types of gaits. Here, we use this fact to examine the relative contributions of the perceptual systems to odometry. We studied a simple homing task in which participants travelled set distances away from an initial starting location (outbound phase), before turning and attempting to walk back to that location (inbound phase). We manipulated whether outbound gait was a walk or a gallop-walk. We also manipulated the outbound availability of optic flow. Inbound reports were performed via walking with eyes closed. Consistent with previous studies of haptic odometry, inbound reports were shorter when the outbound gait was a gallop-walk. We showed that the availability of optic flow decreased this effect. In contrast, the availability of optic flow did not have an observable effect when the outbound gait was walking. We interpreted this to suggest that visual odometry and haptic odometry via walking are similarly calibrated. By measuring the decrease in shortening in the gallop-walk condition, and scaling it relative to the walk condition, we estimated a relative contribution of optic flow to odometry of 41%. Our results present a proof of concept for a new, potentially more generalizable, method for examining the contributions of different perceptual systems to odometry, and by extension, path integration. We discuss implications for understanding human wayfinding.

Crushing of blasted ore is an essential phase in extraction of valuable minerals in mining industry. It is typically performed in multiple stages with each stage producing finer fragmentation. Performance and throughput of the first stage of crushing is highly dependent on the size distribution of the blasted ore. In the crushing plant, a metal grate prevents oversized boulders from getting into the crusher jaws, and a human‐controlled hydraulic manipulator equipped with a rock hammer is required to break oversized boulders and ensure continuous material flow. This secondary breaking task is event‐based in the sense that ore trucks deliver boulders at irregular intervals, thus requiring constant human supervision to ensure continuous material flow and prevent blockages. To automatize such breaking tasks, an intelligent robotic control system along with a visual perception system (VPS) is essential. In this manuscript, we propose an autonomous breaker system that includes a VPS capable of detecting multiple irregularly shaped rocks, a robotic control system featuring a decision‐making mechanism for determining the breaking order when dealing with multiple rocks, and a comprehensive manipulator control system. We present a proof of concept for an autonomous robotic boulder breaking system, which consists of a stereo‐camera‐based VPS and an industrial rock‐breaking manipulator robotized with our retrofitted system design. The experiments in this study were conducted in a real‐world setup, and the results were evaluated based on the success rates of breaking. The experiments yielded an average success rate of 34% and a break pace of 3.3 attempts per minute.

Although only three years have elapsed since the Wassermann-Neisser-Bruck reaction for the diagnosis of syphilis was described, it has become in this time a well-established diagnostic method and it, or its modifications, are now in use in all large medical centers. During this period, which must be considered as a stage of experimentation and testing, a number of modifications of the original method, and also several practically new methods for serum diagnosis have been devised. Several of these have been subjected to critical examination by various investigators, and although from the mass of evidence the original method, with a slight modification, appears to be the most satisfactory, it has seemed to me advisable to carry out a comparative, critical study of the more important modifications. The methods selected for study are the following : Wassermann's original method. Noguchi's precipitation method for spinal fluids, with a discussion of the precipitation reactions of Forges, Fornet, Klausner and Noguchi for blood serum. Bauer's simplification of the Wassermann reaction, with a discussion of Tschernogubow's modification. Noguchi's complement deviation method.

The visual perception system is the most important system for human learning since it receives over 80% of the learning information from the outside world. With the exponential growth of artificial intelligence technology, there is a pressing need for high-energy and area-efficiency visual perception systems capable of processing efficiently the received natural information. Currently, memristors with their elaborate dynamics, excellent scalability, and information (e.g., visual, pressure, sound, etc.) perception ability exhibit tremendous potential for the application of visual perception. Here, we propose a fully memristor-based artificial visual perception nervous system (AVPNS) which consists of a quantum-dot-based photoelectric memristor and a nanosheet-based threshold-switching (TS) memristor. We use a photoelectric and a TS memristor to implement the synapse and leaky integrate-and-fire (LIF) neuron functions, respectively. With the proposed AVPNS we successfully demonstrate the biological image perception, integration and fire, as well as the biosensitization process. Furthermore, the self-regulation process of a speed meeting control system in driverless automobiles can be accurately and conceptually emulated by this system. Our work shows that the functions of the biological visual nervous system may be systematically emulated by a memristor-based hardware system, thus expanding the spectrum of memristor applications in artificial intelligence.

Visual and auditory systems interact at both cortical and subcortical levels. Studies suggest a highly context-specific cross-modal modulation of the auditory system by the visual system. The present study builds on this work by sampling data from 17 young healthy adults to test whether visual speech stimuli evoke different responses in the auditory efferent system compared to visual non-speech stimuli. The descending cortical influences on medial olivocochlear (MOC) activity were indirectly assessed by examining the effects of contralateral suppression of transient-evoked otoacoustic emissions (TEOAEs) at 1, 2, 3 and 4 kHz under three conditions: (a) in the absence of any contralateral noise (Baseline), (b) contralateral noise + observing facial speech gestures related to productions of vowels /a/ and /u/ and (c) contralateral noise + observing facial non-speech gestures related to smiling and frowning. The results are based on 7 individuals whose data met strict recording criteria and indicated a significant difference in TEOAE suppression between observing speech gestures relative to the non-speech gestures, but only at the 1 kHz frequency. These results suggest that observing a speech gesture compared to a non-speech gesture may trigger a difference in MOC activity, possibly to enhance peripheral neural encoding. If such findings can be reproduced in future research, sensory perception models and theories positing the downstream convergence of unisensory streams of information in the cortex may need to be revised.

Providing information via the tactile sensory system allows the pilot to increase awareness without further taxing the visual and auditory perceptual systems. In this study, tactile cues were presented to pilots for target orientation during a simulated helicopter extraction over a moving target. The efficacy of the cues provided by the tactile system was assessed under various conditions (rested vs. fatigued, clear vs. degraded visual environment). This study employed a mixed-model 2(4) factorial design, including one between-subjects variable (training amount: minimal, additional) and three within-subjects variables (state: rested, fatigued; visual environment: clear, degraded; tactile cue belt: active, inactive). Across 2 d under the 4 test conditions, 16 UH-60 rated, healthy aviators completed 8 sessions of 10-min stabilized hovering maneuvers over a moving target. All flights were conducted in a UH-60 flight simulator. Subjects were able to stay closer to the target when the tactile cuing system was active (M = 31.14 ft, SE = 3.17 ft) vs. inactive (M = 36.33 ft, SE = 2.84 ft). Likewise, subjects rated their situation awareness as greater when the tactile system was active vs. inactive. The results support the efficacy of the tactile system in providing directional cues for maintaining pilot performance during a hover maneuver over a moving target.

The method of radiographic diagnosis of pneumoconiosis has been internationally standardized; namely, each film is evaluated according to the profusion, shape, and size of small opacities with reference to preselected standard X-ray films of typical pneumoconiosis [1, 2]. Recently, new diagnostic technologies such as computed tomography (CT) have been introduced, although they are still in the experimental stage [3–5]. In this chapter, we report the results of an objective study performed by many specialists on the applicability of the computed radiography (CR) system in the diagnosis of pneumoconiosis, a field which has a long history.

Serious games are designed and built for an educational primary purpose other than pure entertainment. While team planning and cooperation is essential for the success of the goal of the game, it also plays an essential role in enhancing the believability of the game. Our serious game is in the domain of emergency management, fire fighters in accidents situations. Two contributions are presented in this paper, firstly, enhanced visual perception system that mimic center of attention in humans eye for each NPC along with a short-term memory (working memory) so that NPCs will have access to only limited information and have to build their plans and make their decisions based on what they can perceive from their surrounding environment. Secondly, a distributed HTN planning approach is implemented based on SHOP for the domain of our serious game. Five modules were developed in this part, Controller, World Model, Domain, Interface and HTN Planner. There is two level of planning, team level plans and individual level plans. Plans are generated online based on the information gathered from the visual perception system and stored in the working memory. Our experiment shows The effectiveness of the proposed approach to generate plans.
