In humans, auditory processing differs physiologically between males and females, possibly true for SCA due to gender-specific disease pathophysiological changes. Objective: To investigate gender differences in psychoacoustical abilities, and speech perception in noise in SCA individuals and further compare with normal healthy(NH) population. Methods: 80 SCA and 80 NH normal-hearing participants aged 15-40 years were included and further grouped based on gender. Auditory discrimination for frequency, intensity, and duration at 500Hz and 4000Hz;temporal processing(Gap detection threshold & Modulation Detection Threshold) and Speech Perception In Noise(SPIN) at 0d BSNR tests were evaluated and compared between males and females of SCA and NH population. Results: SCA performed poorer compared to NH for all experimental measures. In the NH population, males performed poorer than females in psychoacoustical measures whereas within the SCA population, the reverse was true. Female participants performed better in the SPIN test in both populations. Conclusions: The adverse impact of SCA on the auditory system due to circulatory changes might cause poorer performance in SCA. Poorer performance by Female SCA is possibly due to the contrary impact of lower Hb level overlying Sickle disease.Estrogen levels and gender preference in auditory processing might lead to better performance by females within the NH population. SPIN performance depends on different attentional demands and sensorimotor processing strategies in noise beyond psychoacoustical processing may lead to better female performance in both populations.展开更多

Individuals from all of society, especially minority groups, feel that they are accepted and they show themselves in a way in the public space. Even though the perception and usage of public space have changed in time, people still feel free themselves in these areas. However, ‘terrorism’, which is a reality in today's world, is one of the cases which pose danger to the public spaces. Thus, the image of these areas has changed from “the areas where individuals they feel freer” to “the areas where people are vulnerable to many potential attacks”. This study tells you how the public perception has changed over time and examine the intended use of the public due to these changes. Terrorist activities increased all of the World and public spaces of the individual in the face of this reality, perception and Jane Jacobs, urban life and public relations with the charm of the terrorist phenomenon is one of the main problems the 21st century in the context of views on security are discussed.

However, to our knowledge, no objective test has been developed to quantify self-motion perception during clinical vestibular evaluation.ObjectiveThe main objective of the present study was to quantify vestibular perception during caloric vestibular stimulation using a tachometer.MethodsTwenty-two participants were divided into three groups: 1) younger healthy adults, 2) older healthy adults and 3) vestibular impaired adults. All participants performed bithermal water caloric irrigation during which slow-phase eye velocity (SPV) was measured using videonystagmography and self-motion velocity perception was assessed using a handheld tachometer (RPM).ResultsThe results revealed a significant difference in SPV between vestibular impaired ears and both healthy groups, and a significant difference in self-motion velocity perception between healthy young and vestibular impaired participants.ConclusionsThis study suggest that the SPV similarly to self-motion perception (RPM) can differentiate between vestibular impaired and young healthy participants. Future work is required to assess the influence of self-motion perception in aging.展开更多

Common among African-American women, patients suffering from them often arrive late to the hospital in our African regions. This study aimed to investigate the knowledge and perception of uterine fibroids among women who came to the gynecology-obstetrics department of the Regional Hospital Center (CHR) Tsévié. Methodology: It was a cross-sectional descriptive study, with data collection conducted from May 7th to 20th, 2024, using systematic sampling. The study included all women present in the Gynecology-Obstetrics Department of CHR Tsévié during the study period who willingly and informedly consented to participate in the survey. Results: 362 women participated in the study. Among them, 36.8% had a secondary level, and 72.9% were Christians. About 97.5% had heard of uterine fibroids. In 63.5% of cases, their entourage was the principal source of information. The diagnostic methods mentioned by the women were ultrasound in 94.6% of cases, while prayers and occultism were also cited in 28% and 33.3% of cases, respectively. While 91.9% of the women considered the hospital, the place for treatment, some indicated that treatment would require plant-based approaches (46.8%) and prayers (26%). The cost of treatment was an obstacle for 85.4% of women, and 61.3% expressed fear of dying during surgery. There was a statistically significant relationship between treatment choice and religion. Conclusion: The majority of women had heard of uterine fibroids but had incorrect information about the treatment.展开更多

Perception-driven rendering techniques generate images with minimal noise and distortion that are generally acceptable to the human visual system, thereby reducing rendering costs. In this paper, we introduce a perception-entropy-driven temporal reusing method to accelerate real-time ray tracing. We first build a just noticeable difference(JND) model to represent the uncertainty of ray samples and image space masking effects. Then, we expand the shading gradient through gradient max-pooling and gradient filtering to enlarge the visual receipt field. Finally, we dynamically optimize reusable time segments to improve the accuracy of temporal reusing. Compared with Monte Carlo ray tracing, our algorithm enhances frames per second(fps) by 1.93× to 2.96× at 8 to 16 samples per pixel, significantly accelerating the Monte Carlo ray tracing process while maintaining visual quality.展开更多

文摘Objectives:This study aimed to explore the perceptions and recommendations of multiparas and health-related professionals regarding appropriate birth intervals(Bis)and key determinants.Methods:In-depth semi-structured interviews were conducted between April 1 and June 30,2022.Nine multiparas and thirteen health-related professionals were purposefully sampled until data saturation was reached.A thematic analysis approach was applied to the interview transcripts,utilizing dual independent coding and consensus validation in NVivo 12.0.Results:The data generated two overarching categories:1)balanced decision-making on the appropriate birth intervals and 2)internal and external determinants integrated with health and societal considerations.Four key themes emerged following the two categories:1)consistency and discrepancy between the actual and recommended birth intervals of multiparas;2)health-and developmentoriented professional recommendations;3)internal determinants related to individual-level factors;and 4)external determinants related to child-related factors,family support,and social security.Weighing women's reproductive health and career development,multiparas and health-related professionals perceived a length between 18 and 36 months as the appropriate Bl.Conclusion:Multiparas and health-related professionals shaped their balanced recommendations on a relatively appropriate birth interval ranging from 18 to 36 months,which was influenced by women's individual-level factors,child-related factors,family support,and social security.Targeted social and healthcare services should be offered to women and their families during the Bls.
文摘This study explores the environmental sensitivity of first-year teacher education stu dents,focusing on the relationship between their Earth Science performance,demographic factors,and their cognitive and emotional responses to environmental challenges.Using a descriptive correlational design within a mixed-methods framework,the research incorporates tools such as the Environmental Sensitivity Test(EST),focus group discussions(FGDs),and eco-mapping to comprehensively collect and analyze data.The findings reveal that while students exhibit a general awareness of environmental issues,this awareness does not consistently translate into sustainable practices,particularly in areas such as water conservation and waste management.A weak and statistically insignificant correlation was identified between Earth Science performance and environmental sensitivity,indicating that academic achievement in the subject does not necessarily lead to environmentally responsible behaviors.The results underscore the importance of teacher education programs integrating principles of behavioral psychology,experiential learning,and focused environmental education.Specifically,secondary science teachers should be equipped with practical strategies,such as implementing project-based learning,organizing community-centered environmental initiatives,and fostering interdisciplinary approaches to sustainability.These interventions address the gap in preparing future educators to effectively advocate for and implement sustainable practices.Strengthening teacher preparation programs with these components ensures that science educators are better equipped to cultivate a new generation of environmentally responsible citizens.
文摘By comparing price plans offered by several retail energy firms,end users with smart meters and controllers may optimize their energy use cost portfolios,due to the growth of deregulated retail power markets.To help smart grid end-users decrease power payment and usage unhappiness,this article suggests a decision system based on reinforcement learning to aid with electricity price plan selection.An enhanced state-based Markov decision process(MDP)without transition probabilities simulates the decision issue.A Kernel approximate-integrated batch Q-learning approach is used to tackle the given issue.Several adjustments to the sampling and data representation are made to increase the computational and prediction performance.Using a continuous high-dimensional state space,the suggested approach can uncover the underlying characteristics of time-varying pricing schemes.Without knowing anything regarding the market environment in advance,the best decision-making policy may be learned via case studies that use data from actual historical price plans.Experiments show that the suggested decision approach may reduce cost and energy usage dissatisfaction by using user data to build an accurate prediction strategy.In this research,we look at how smart city energy planners rely on precise load forecasts.It presents a hybrid method that extracts associated characteristics to improve accuracy in residential power consumption forecasts using machine learning(ML).It is possible to measure the precision of forecasts with the use of loss functions with the RMSE.This research presents a methodology for estimating smart home energy usage in response to the growing interest in explainable artificial intelligence(XAI).Using Shapley Additive explanations(SHAP)approaches,this strategy makes it easy for consumers to comprehend their energy use trends.To predict future energy use,the study employs gradient boosting in conjunction with long short-term memory neural networks.

文摘Background:It has been reported that factors such as age and vestibular pathology (i.e. vestibular migraine) could impact self-motion perception during vestibular stimulation. However, to our knowledge, no objective test has been developed to quantify self-motion perception during clinical vestibular evaluation.ObjectiveThe main objective of the present study was to quantify vestibular perception during caloric vestibular stimulation using a tachometer.MethodsTwenty-two participants were divided into three groups: 1) younger healthy adults, 2) older healthy adults and 3) vestibular impaired adults. All participants performed bithermal water caloric irrigation during which slow-phase eye velocity (SPV) was measured using videonystagmography and self-motion velocity perception was assessed using a handheld tachometer (RPM).ResultsThe results revealed a significant difference in SPV between vestibular impaired ears and both healthy groups, and a significant difference in self-motion velocity perception between healthy young and vestibular impaired participants.ConclusionsThis study suggest that the SPV similarly to self-motion perception (RPM) can differentiate between vestibular impaired and young healthy participants. Future work is required to assess the influence of self-motion perception in aging.
文摘Aiming at the problems of traditional guide devices such as single environmental perception and poor terrain adaptability,this paper proposes an intelligent guide system based on a quadruped robot platform.Data fusion between millimeter-wave radar(with an accuracy of±0.1°)and an RGB-D camera is achieved through multisensor spatiotemporal registration technology,and a dataset suitable for guide dog robots is constructed.For the application scenario of edge-end guide dog robots,a lightweight CA-YOLOv11 target detection model integrated with an attention mechanism is innovatively adopted,achieving a comprehensive recognition accuracy of 95.8% in complex scenarios,which is 2.2% higher than that of the benchmark YOLOv11 network.The system supports navigation on complex terrains such as stairs(25 cm steps)and slopes(35°gradient),and the response time to sudden disturbances is shortened to 100 ms.Actual tests show that the navigation success rate reaches 95% in eight types of scenarios,the user satisfaction score is 4.8/5.0,and the cost is 50% lower than that of traditional guide dogs.

文摘It is significant to process textures with special functions similar to animal surfaces based on bionics and improve the friction stability and contact comfort of contact surfaces for the surface texture design of tactile products.In this paper,a bionic hexagonal micro-convex texture was prepared on an acrylic surface by laser processing.The friction mechanism of a finger touching the bionic hexagonal micro-convex texture under different touch speeds and pressures,and the effect of the height of the texture on tactile perception were investigated by finite element,subjective evaluation,friction,and EEG tests.The results showed that the deformation friction was the main friction component when the finger touched the bionic hexagonal texture,and the slipperiness and friction factor showed a significant negative correlation.As the touch speed decreased or the touch force increased,the hysteresis friction of the fingers as well as the interlocking friction increased,and the slipperiness perception decreased.The bionic hexagonal texture with higher convexity caused a higher friction factor,lower slipperiness perception,and lower P300 peak.Hexagonal textures with lower convexity,lower friction factor,and higher slipperiness perception required greater brain attentional resources and intensity of tactile information processing during tactile perception.

文摘This study constructed a moderated mediation model to examine how the social support received by teachers is associated with their work pay fairness perception in relation to their job satisfaction and job performance.Data were collected from 2411 preschool teachers in China(female=98.01%;mean age=29.12 years,SD=6.28 years).These data were analyzed using structural equation modelling,bootstrapping and latent moderate structural equations.The results indicated that teachers’perception of pay fairness is directly associated with self-rated job performance.Additionally,pay fairness perceptions have an indirect effect on higher job performance through job satisfaction.The social support that teachers perceive moderates the relationship between pay fairness perception and job satisfaction:the more social support teachers receive,the weaker the impact of pay fairness perception on job satisfaction.Thesefindings suggest that teachers’perception of pay fairness is related to their sense of quality of work life,as indicated by their job satisfaction and performance.

文摘Neuromorphic devices,inspired by the intricate architecture of the human brain,have garnered recognition for their prodigious computational speed and sophisticated parallel computing capabilities.Vision,the primary mode of external information acquisition in living organisms,has garnered substantial scholarly interest.Notwithstanding numerous studies simulating the retina through optical synapses,their applications remain circumscribed to single-mode perception.Moreover,the pivotal role of temperature,a fundamental regulator of biological activities,has regrettably been relegated to the periphery.To address these limitations,we proffer a neuromorphic device endowed with multimodal perception,grounded in the principles of light-modulated semiconductors.This device seamlessly accomplishes dynamic hybrid visual and thermal multimodal perception,featuring temperature-dependent paired pulse facilitation properties and adaptive storage.Crucially,our meticulous examination of transfer curves,capacitance–voltage(C–V)tests,and noise measurements provides insights into interface and bulk defects,elucidating the physical mechanisms underlying adaptive storage and other functionalities.Additionally,the device demonstrates a variety of synaptic functionalities,including filtering properties,Ebbinghaus curves,and memory applications in image recognition.Surprisingly,the digital recognition rate achieves a remarkable value of 98.8%.
文摘Introduction: Uterine fibroids are benign tumors that develop from the connective and muscular tissues of the uterus. Common among African-American women, patients suffering from them often arrive late to the hospital in our African regions. This study aimed to investigate the knowledge and perception of uterine fibroids among women who came to the gynecology-obstetrics department of the Regional Hospital Center (CHR) Tsévié. Methodology: It was a cross-sectional descriptive study, with data collection conducted from May 7th to 20th, 2024, using systematic sampling. The study included all women present in the Gynecology-Obstetrics Department of CHR Tsévié during the study period who willingly and informedly consented to participate in the survey. Results: 362 women participated in the study. Among them, 36.8% had a secondary level, and 72.9% were Christians. About 97.5% had heard of uterine fibroids. In 63.5% of cases, their entourage was the principal source of information. The diagnostic methods mentioned by the women were ultrasound in 94.6% of cases, while prayers and occultism were also cited in 28% and 33.3% of cases, respectively. While 91.9% of the women considered the hospital, the place for treatment, some indicated that treatment would require plant-based approaches (46.8%) and prayers (26%). The cost of treatment was an obstacle for 85.4% of women, and 61.3% expressed fear of dying during surgery. There was a statistically significant relationship between treatment choice and religion. Conclusion: The majority of women had heard of uterine fibroids but had incorrect information about the treatment.

文摘Although ray tracing produces high-fidelity, realistic images, it is considered computationally burdensome when implemented on a high rendering rate system. Perception-driven rendering techniques generate images with minimal noise and distortion that are generally acceptable to the human visual system, thereby reducing rendering costs. In this paper, we introduce a perception-entropy-driven temporal reusing method to accelerate real-time ray tracing. We first build a just noticeable difference(JND) model to represent the uncertainty of ray samples and image space masking effects. Then, we expand the shading gradient through gradient max-pooling and gradient filtering to enlarge the visual receipt field. Finally, we dynamically optimize reusable time segments to improve the accuracy of temporal reusing. Compared with Monte Carlo ray tracing, our algorithm enhances frames per second(fps) by 1.93× to 2.96× at 8 to 16 samples per pixel, significantly accelerating the Monte Carlo ray tracing process while maintaining visual quality.

文摘With the increasing importance of multimodal data in emotional expression on social media,mainstream methods for sentiment analysis have shifted from unimodal to multimodal approaches.However,the challenges of extracting high-quality emotional features and achieving effective interaction between different modalities remain two major obstacles in multimodal sentiment analysis.To address these challenges,this paper proposes a Text-Gated Interaction Network with Inter-Sample Commonality Perception(TGICP).Specifically,we utilize a Inter-sample Commonality Perception(ICP)module to extract common features from similar samples within the same modality,and use these common features to enhance the original features of each modality,thereby obtaining a richer and more complete multimodal sentiment representation.Subsequently,in the cross-modal interaction stage,we design a Text-Gated Interaction(TGI)module,which is text-driven.By calculating the mutual information difference between the text modality and nonverbal modalities,the TGI module dynamically adjusts the influence of emotional information from the text modality on nonverbal modalities.This helps to reduce modality information asymmetry while enabling full cross-modal interaction.Experimental results show that the proposed model achieves outstanding performance on both the CMU-MOSI and CMU-MOSEI baseline multimodal sentiment analysis datasets,validating its effectiveness in emotion recognition tasks.
