In this paper,we mainly discuss a discrete estimation of the average differential entropy for a continuous time-stationary ergodic space-time random field.By estimating the probability value of a time-stationary random field in a small range,we give an entropy estimation and obtain the average entropy estimation formula in a certain bounded space region.It can be proven that the estimation of the average differential entropy converges to the theoretical value with a probability of 1.In addition,we also conducted numerical experiments for different parameters to verify the convergence result obtained in the theoretical proofs. 展开更多

Underwater monopulse space-time adaptive track-before-detect method,which combines space-time adaptive detector(STAD)and the track-before-detect algorithm based on dynamic programming(DP-TBD),denoted as STAD-DP-TBD,can effectively detect low-speed weak targets.However,due to the complexity and variability of the underwater environment,it is difficult to obtain sufficient secondary data,resulting in a serious decline in the detection and tracking performance,and leading to poor robustness of the algorithm.In this paper,based on the adaptive matched filter(AMF)test and the RAO test,underwater monopulse AMF-DP-TBD algorithm and RAO-DP-TBD algorithm which incorporate persymmetry and symmetric spectrum,denoted as PSAMF-DP-TBD and PS-RAO-DP-TBD,are proposed and compared with the AMF-DP-TBD algorithm and RAO-DP-TBD algorithm based on persymmetry array,denoted as P-AMF-DP-TBD and P-RAO-DP-TBD.The simulation results show that the four methods can work normally with sufficient secondary data and slightly insufficient secondary data,but when the secondary data is severely insufficient,the P-AMF-DP-TBD and P-RAO-DP-TBD algorithms has failed while the PSAMF-DP-TBD and PS-RAO-DP-TBD algorithms still have good detection and tracking capabilities. 展开更多

In the context of the cultural development of the new era and the burgeoning spiritual demands of the people,there has been a remarkable surge in the proliferation of traditional Chinese cultural programs.The“Chinese Festivals”series,produced by Henan TV,standing out as an engaging TV program that showcases traditional Chinese culture,has rapidly captivated a diverse audience across different age groups,creating a rich,multi-dimensional,and cross-media cultural communication ecosystem.The program strategically selects symbolic elements by systematically categorizing and organizing traditional Chinese cultural symbols to create a rich cultural space.It employs cutting-edge scientific and technological methods to enrich viewer immersion,crafting media rituals with both temporal significance and a profound sense of media ritual.This approach boosts the program’s popularity and sets a benchmark for industry innovation.By fostering an interactive narrative between mainstream media and the public,the program continuously broadens the scope of the“story world,”fostering a harmonious and structured national cultural community through the creative interpretation of traditional Chinese culture and the evocative crafting of the aesthetic sensibilities inherent in Chinese art.It is worth noting that the phenomenon of aesthetic fatigue besets the development of this serial program.To address this issue and further improve the appeal of the program,a comprehensive approach is required to develop a cohesive narrative mode for the“story world.”This involves harmonizing the interplay between artistic endeavors and technological advancements,synchronizing sensory experiences with the foundational ritualistic elements,and enhancing the effectiveness of the media communication matrix to construct a brand of media culture that has social significance,aesthetic value,and economic profits in the new era. 展开更多

BACKGROUND Acute pancreatitis(AP),as a common acute abdomen disease,has a high incidence rate worldwide and is often accompanied by severe complications.Negative emotions lead to increased secretion of stress hormones,elevated blood sugar levels,and enhanced insulin resistance,which in turn increases the risk of AP and significantly affects the patient's quality of life.Therefore,exploring the intervention effects of narrative nursing programs on the negative emotions of patients with AP is not only helpful in alleviating psychological stress and improving quality of life but also has significant implications for improving disease outcomes and prognosis.AIM To construct a narrative nursing model for negative emotions in patients with AP and verify its efficacy in application.METHODS Through Delphi expert consultation,a narrative nursing model for negative emotions in patients with AP was constructed.A non-randomized quasi-experimental study design was used in this study.A total of 92 patients with AP with negative emotions admitted to a tertiary hospital in Nantong City of Jiangsu Province,China from September 2022 to August 2023 were recruited by convenience sampling,among whom 46 patients admitted from September 2022 to February 2023 were included in the observation group,and 46 patients from March to August 2023 were selected as control group.The observation group received narrative nursing plan,while the control group was given with routine nursing.Self-rating anxiety scale(SAS),self-rating depression scale(SDS),positive and negative affect scale(PANAS),caring behavior scale,patient satisfaction scale and 36-item short form health survey questionnaire(SF-36)were used to evaluate their emotions,satisfaction and caring behaviors in the two groups on the day of discharge,1-and 3-month following discharge.RESULTS According to the inclusion and exclusion criteria,a total of 45 cases in the intervention group and 44 cases in the control group eventually recruited and completed in the study.On the day of discharge,the intervention group showed significantly lower scores of SAS,SDS and negative emotion(28.57±4.52 vs 17.4±4.44,P<0.001),whereas evidently higher outcomes in the positive emotion score,Caring behavior scale score and satisfaction score compared to the control group(P<0.05).Repeated measurement analysis of variance showed that significant between-group differences were found in time effect,inter-group effect and interaction effect of SAS and PANAS scores as well as in time effect and inter-group effect of SF-36 scores(P<0.05);the SF-36 scores of two groups at 3 months after discharge were higher than those at 1 month after discharge(P<0.05).CONCLUSION The application of narrative nursing protocols has demonstrated significant effectiveness in alleviating anxiety,ameliorating negative emotions,and enhancing satisfaction among patients with AP. 展开更多

Süskind’s “Perfume” constructs the story frame of the text through three sets of contradictory narratives, exploring the process of Grenouille, who is regarded as an alien by others, trying to find and construct true meaning of being a human being from three aspects: human smell, emotion, and discourse. This process constantly encounters deconstruction from its own smelllessness, senselessness and aphasia, thereby implying the lack of human subjectivity and value through Grenouille’s failure to find identity. It also uses the image of perfume to express the author’s deep concerns about the loss of subjectivity, the disillusionment of classical morality, and the violence of industrial civilization in France and even Europe in the eighteenth century. 展开更多

This paper presents a physically plausible and somewhat illuminating first step in extending the fundamental principles of mechanical stress and strain to space-time. Here the geometry of space-time, encoded in the metric tensor, is considered to be made up of a dynamic lattice of extremely small, localized fields that form a perfectly elastic Lorentz symmetric space-time at the global (macroscopic) scale. This theoretical model of space-time at the Planck scale leads to a somewhat surprising result in which matter waves in curved space-time radiate thermal gravitational energy, as well as an equally intriguing relationship for the anomalous dispersion of light in a gravitational field. 展开更多

The emerging virtual coupling technology aims to operate multiple train units in a Virtually Coupled Train Set(VCTS)at a minimal but safe distance.To guarantee collision avoidance,the safety distance should be calculated using the state-of-the-art space-time separation principle that separates the Emergency Braking(EB)trajectories of two successive units during the whole EB process.In this case,the minimal safety distance is usually numerically calculated without an analytic formulation.Thus,the constrained VCTS control problem is hard to address with space-time separation,which is still a gap in the existing literature.To solve this problem,we propose a Distributed Economic Model Predictive Control(DEMPC)approach with computation efficiency and theoretical guarantee.Specifically,to alleviate the computation burden,we transform implicit safety constraints into explicitly linear ones,such that the optimal control problem in DEMPC is a quadratic programming problem that can be solved efficiently.For theoretical analysis,sufficient conditions are derived to guarantee the recursive feasibility and stability of DEMPC,employing compatibility constraints,tube techniques and terminal ingredient tuning.Moreover,we extend our approach with globally optimal and distributed online EB configuration methods to shorten the minimal distance among VCTS.Finally,experimental results demonstrate the performance and advantages of the proposed approaches. 展开更多

In the Heart of the Country,the second novel by J.M.Coetzee,has been traditionally read as a disembodied writing that focuses on the problem of writing per se instead of the reality.This paper contends that the work is actually a body narrative that explores the visceral pain suffered by Magda whose infertile body impedes her being a qualified subject.As the heroine in a postcolonial novel,Magda is not just a body that is restricted and constructed by the politics of the body,but also a thinking and writing body that consciously questions and resists the gendered bodily norms under whose yardstick her subjecthood is barred.Written in the metafictional manner,Magda’s narrative of the body is not just a record of her corporeal experience,but also a self-conscious negotiation with,and challenge of,the bodily norms under whose yardstick her body has been debased or,in terms of Judith Butler,abjected.Taking her female bodily experience as the starting point,Magda writes a feminine text that values passion,fluidity and non-linearity to disrupt the patriarchal discourse underpinned with logical reasoning.The feminine body narrative endeavors to achieve a new way of communication through which a reciprocal cross race/gender relationship might be established. 展开更多

A new scheme combining a scalable transcoder with space time block codes (STBC) for an orthogonal frequency division multiplexing (OFDM) system is proposed for robust video transmission in dispersive fading channels. The target application for such a scalable transcoder is to provide successful access to the pre-encoded high quality video MPEG-2 from mobile wireless terminals. In the scalable transcoder, besides outputting the MPEG-4 fine granular scalability (FGS) bitstream, both the size of video frames and the bit rate are reduced. And an array processing algorithm of layer interference suppression is used at the receiver which makes the system structure provide different levels of protection to different layers. Furthermore, by considering the important level of scalable bitstream, the different bitstreams can be given different level protection by the system structure and channel coding. With the proposed system, the concurrent large diversity gain characteristic of STBC and alleviation of the frequency-selective fading effect of OFDM can be achieved. The simulation results show that the proposed schemes integrating scalable transcoding can provide a basic quality of video transmission and outperform the conventional single layer transcoding transmitted under the random and bursty error channel conditions. 展开更多
