Abstract： Among various methods to detect the ship targets in Synthetic Aperture Radar（SAR） image, the Constant False Alarm Rate (CFAR) detection algorithm with an adaptive detection threshold is the most important and extensively used one. In order to improve the detection performance of the ships in SAR image, various statistical distributions are used, with an attempt to accurately model the SAR clutter backgrounds, such as Gamma, K, log-normal, G0, the alpha-stable distribution, etc. In modern radar systems, the use of the CFAR technique is necessary to keep the false alarms at a suitably low rate in an a priori unknown time varying and spatially nonhomogeneous backgrounds, and to improve the detection probability as much as possible. The clutter background in SAR images is complicated and variable, when the actual clutter background deviates from the assumed statistical distribution, the performance of the parametric CFAR detectors will deteriorate, whereas the nonparametric CFAR method will exhibit its advantage. In this work, the Wilcoxon nonparametric CFAR scheme for ship detection in SAR image is proposed and analyzed. By comparison with several typical parametric CFAR schemes on 3 real SAR images of Radarsat-2, ICEYE-X6 and Gaofen-3, the robustness of the Wilcoxon nonparametric detector to maintain a good false alarm performance in these different detection backgrounds is revealed, and its detection performance for the weak ship is improved evidently. Moreover, the detection speed of the Wilcoxon nonparametric detector is fast and it has the simplicity of hardware implementation.

Abstract： Good human-pet relationship can bring many benefits to human beings, but the internal mechanism of intimate and important human-pet relationship is still unclear. It may be that due to prolonged close contact, pet owners will treat their pets as part of the family, and may even integrate pets into their self-concept, showing a processing advantage in the processing of pet-related information./t/nBased on this, this research adopts three studies to systematically investigate the relationship between pet owners and pets. Specifically speaking, in study 1, the IOS scale, self-concept questionnaire and anthropomorphic scale were used to examine the relationship between the self-concept of pets and pet owners. In study 2, R/K paradigm was used to investigate the processing characteristics of pet-related information by pet owners in terms of memory processing, and to confirm the existence of the reference effect of pets. Study 3 further used ERP technology to investigate the pet reference processing bias of pet owners from an electrophysiological perspective./t/nThe results showed that: (1) Compared with non-pet owners, pet owners would integrate pets into their self-concept and form the pet self, in which anthropomorphism played an intermediary role. (2) Pet owners have a stronger memory processing advantage for pet-related information, the recognition rate of the pet reference is significantly higher than celebrity reference and semantic reference, and is similar to self-reference and mother reference. (3) The induced LPC amplitude of pet reference was significantly higher than celebrity reference, but similar to mother reference, and significantly lower than self-reference./t/nIn conclusion, the present research demonstrated that pet owners will regard their pets as part of themselves, forming the pet self, and showing the pet reference effect on memory, but the pet self is essentially a relational self, and there is still a certain distance from the core self. Current research on the self focuses on significant others, but doesn’t involve the field of pets. More importantly, it is necessary for us to consider the impact of pets on individuals. Pet owners often treat their pets as important family members, creating a close bond that can help individuals recognize their pets as an extension of themselves and contribute to the positive impact that pets can have on their physical and mental health.

Abstract： The identifiability of cognitive diagnosis models relies heavily on the completeness of the Q matrix. However, existing test designs primarily focus on dichotomously-scored items, neglecting the importance of polytomous cognitive diagnostic test design. Moreover, this limitation poses a significant obstacle to the advancement of cognitive diagnosis. To bridge this gap, this paper aimed to introduce novel designs for the construction of polytomous structured and unstructured simplest complete Q matrices (SSCQM/USCQM). Our proposed approach considered all ideal response patterns (IRPs) of knowledge states (KSs) on the reachability matrix as research objects, with the objective of minimizing the number of columns selected from the reachability matrix. This ensured one-to-one correspondence between the set of KSs and the set of IRPs, thereby enhancing the completeness of the SSCQM. Additionally, we derived a polytomous USCQM by considering the relationship between the SSCQM and the sub-matrix of the corresponding identity matrix while ensuring that each row contains at least one 1 . Interestingly, the construction process revealed that there were more USCQMs than SSCQMs. This innovative approach expanded the possibilities for polytomous cognitive diagnostic test design.
This study focused on the design and evaluation of cognitive diagnostic tests using polytomous structured and unstructured Q matrices (SSCQM/USCQM). We conducted two studies to comprehensively examine the influence of factors such as the number of attributes, attribute hierarchies, and item parameters on the precision of the SSCQM, USCQM, and reachability matrix. In the first study, variations in attribute structures and item parameter values were investigated to understand their impact on Q matrix accuracy. On the other hand, the second study explored the effects of attribute hierarchies and the number of attributes on the precision of the SSCQM, USCQM, and reachability matrix.
Both simulation studies and actual measurement data were utilized to assess the robustness and efficacy of the two methods. Firstly, the simulation results revealed several key findings. Notably, increasing the number of SSCQMs or USCQMs positively influenced the accuracy of the results. In the context of long tests, the USCQM demonstrated higher Pattern Match Ratio (PMR) and Marginal Match Ratio (MMR) compared to the SSCQM and the reachability matrix. This trend was particularly evident when there was an increase in item parameters, attribute numbers, or a change in attribute hierarchy. However, it is noteworthy that, regardless of these various factors, the PMR and MMR of the three tests exhibited minimal differences. On the other hand, in short tests with good item quality, the SSCQM achieved the best performance compared to other methods. This highlights the importance of considering specific test characteristics and item quality when selecting the appropriate Q matrix type. These findings provide valuable insights into the factors that influence the precision of Q matrices. They emphasize the benefits of increasing the number of matrices, understanding the impact of item parameters, and recognizing the performance disparities among different matrix types. Obtaining a comprehensive understanding of these relationships is vital for optimizing the design and implementation of cognitive diagnostic testing, ultimately guaranteeing accurate assessments of individual knowledge states. Secondly, analysis of the actual measurement data showed high identification repetition rates for the SSCQM and the reachability matrix, with a minimal difference in attribute mastery ratio.
In summary, both the SSCQM and the USCQM demonstrate adequate performance when compared to other Q matrices under similar conditions. These findings emphasize the significance of prioritizing completeness in cognitive diagnostic testing. This research seeks to contribute to the advancement of cognitive diagnosis by addressing the limitations of existing test designs and introducing new techniques for constructing polytomous Q matrices. In addition, the findings presented in this paper offer valuable insights for researchers and practitioners seeking to design high-quality cognitive diagnostic tests that accurately assess individual knowledge states.

Abstract： The emotional information conveyed through phonological prosody and facial expressions forms the foundation for human interpretation of others’ emotions and facilitates interpersonal interactions. Investigating how infants perceive, discriminate, and evaluate emotions embedded in these two modalities deepens our understanding of infants’ cognitive development and neural mechanisms. This paper comprehensively reviews emotion processing in infants, revealing that the temporal and frontal cortex play crucial roles in processing emotional speech and facial expressions. Although emotional processing involves both brain hemispheres, infants initially show a right-hemisphere advantage similar to adults. Within the first week after birth, infants can distinguish emotional information and exhibit a processing bias toward positive emotions. The bias gradually shifts to favor negative emotions around six months of age. By twelve months, infants’ negative emotional biases stabilize, and they can understand and respond to emotional cues from speech and facial expressions. Based on these findings, we propose the Developmental Theory of Emotional Bias. Importantly, cross-modal visual-auditory information significantly enhances infants’ ability to discern and understand specific emotions.

Abstract： In this paper, the gravitational lensing of a static neutron star with magnetic moment and magnetic charge is studied. In the spacetime of such a neutron star, the deflection angle of a photon is directly proportional to the neutron star’s magnetic charge and mass-to-distance ratio, while inversely proportional to the magnetic moment of the neutron star. Specifically, when the magnetic charge is 0.5, the deflection angle is constant, independent of changes in the magnetic moment. When both the magnetic moment and the magnetic charge approach zero, all parameters revert to the Schwarzschild case.

Abstract： We introduce a novel random integration algorithm that boasts both high con#2;
vergence order and polynomial tractability for functions characterized by sparse
frequencies or rapidly decaying Fourier coefficients. Specifically, for integration in
periodic isotropic Sobolev space and the isotropic Sobolev space with compact sup#2;
port, our approach attains a near-optimal root mean square error. In contrast to
previous nearly optimal algorithms, our method exhibits polynomial tractability,
ensuring that the number of samples does not scale exponentially with increasing
dimensions. Our integration algorithm also enjoys near-optimal bound for weighted
Korobov space. Furthermore, the algorithm can be applied without the need for
prior knowledge of weights, distinguishing it from component-by-component algo#2;
rithms. For integration in the Wiener algebra, the sample complexity of our algo#2;
rithm is independent of the decay rate of Fourier coefficients. The effectiveness of
the integration is confirmed through numerical experiments.

Abstract： Abstract: Public toilets reflect human civilization, embodying not only social efficiency but also gender equality. However, the current widespread issue of insufficient and mismatched toilet spaces persists. The demand for toilet facilities by men and women is not simply a matter of population ratios. Due to differences in wait times, arrival time distributions, and the ability for men to switch to urinals, the traditional queuing theory is not precise enough for this issue. This study investigates the usage of public toilets and constructs a simulation system based on agent-based modeling. Using this system, the toilet space requirements for gender-segregated and non-segregated toilets are measured under different satisfaction rates, foot traffic volumes, and toilet usage frequencies. Additionally, the consistency between the real distribution of time spent entering and exiting toilets and the simulation system is verified, demonstrating the robustness of the conclusions drawn. The study concludes that under a fixed satisfaction rate, the number of toilet stalls satisfies a specific function of foot traffic volume. The agent-based modeling approach demonstrated in this study can be extended to address other complex real-world optimization problems.

Abstract： Background Acute rheumatic feve and post-streptococcal reactive arthritis are known to be immune mediated consequences of streptococcal infection，whereas the dangers of streptococcal infection in rheumatoid arthritis have rarely been reported，and the present study evaluated the relationship of streptococcal infection on readmission in patients with RA. Objective The aim of this study was to investigate the relationship between traditional Chinese medicine and the readmission rate of patients with rheumatoid arthritis combined with streptococcal infection（RA-ASO）through a retrospectivecohort study. Methods We used the information system（HIS）database of the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine in the past to select the data of RA patients from June 2013 to June 2021. A total of 1233 RA patients were included，and patients were categorized into RA-only group（989 patients）and RA-ASO group（244 patients）according to whether they were combined with ASO（streptococcus>50 kU/L）. The RA-ASO patients were then divided into the herbal medicine group（113 cases）and the non-herbal medicine group（113 cases）using the 1:1 propensity score matching principle. Univariate and multivariate Cox regression analyses and Kaplan-Meier survival curve analyses were used to explore the risk factors for readmission in RA-ASO patients. The top 20 herbal medicines used in 113 patients in the TCM group were also clustered by clustering and analyzed by association rule with the reduction of readmission. Results The results showed that the mean age of patients and the percentage of elderly people aged 60-89 years were lower in the RA-ASO group than in the RA-only group，and the rates of slow-acting antirheumatic drugs，glucocorticoid use，readmission，and streptococci were higher than in the RA only group（P<0.05）. One-way Cox proportional risk regression analysis showed that men（HR=1.01，95%CI=1.01-1.01，P<0.01），osteoarthritis（HR=1.65，95%CI=1.07-2.54，P=0.02），and interstitial pneumonia（HR=1.63，95%CI=1.11-2.39，P=0.01），RA-ASO patients with glucocorticoid use （HR=1.51，95%CI=1.02-2.22，P=0.04）had an elevated risk of readmission，and the use of traditional Chinese medicine（HR=0.57，95%CI=0.39-0.83，P<0.01）of RA-ASO patients had a reduced risk of readmission. Multifactorial Cox proportional risk regression analysis showed that RA-ASO patients with interstitial pneumonia（HR=1.54，95%CI=1.02-2.32，P=0.04）and elevated erythrocyte sedimentation rate（HR=1.78，95%CI=1.06-3.00，P=0.03）had an increased risk of readmission；patients with traditional Chinese medicine（HR=0.48，95%CI=0.31-0.75，P<0.01）had a decreased risk of readmission in RA-ASO patients. The results of Kaplan-Meier survival curve analysis showed that the readmission rate of RA-ASO patients in the Chinese medicine group was lower than that in the non-Chinese medicine group（χ2 =10.989，P<0.001），and that the readmission rate of RA-ASO patients in the Chinese medicine group was lower than that of female patients in the non-Chinese medicine group（χ2 =4.118，P=0.042）. Among them，the reduction of readmission was strongly associated with the Chinese medicines of zedoary，peach kernel，and dandelion. Conclusion This study found that TCM treatment may be associated with a lower readmission rate in RA-ASO patients. For patients with RA-ASO，TCM treatment may be considered to reduce patient readmission.
