Patterns of Interactions of the Complex City System:Emotional Urban Objects as Triggering Agents-A Secondary Publication

This article presents an analysis of the patterns of interactions resulting from the positive and negative emotional events that occur in cities,considering them as complex systems.It explores,from the imaginaries,how certain urban objects can act as emotional agents and how these events affect the urban system as a whole.An adaptive complex systems perspective is used to analyze these patterns.The results show patterns in the processes and dynamics that occur in cities based on the objects that affect the emotions of the people who live there.These patterns depend on the characteristics of the emotional charge of urban objects,but they can be generalized in the following process:(1)immediate reaction by some individuals;(2)emotions are generated at the individual level which begins to generalize,permuting to a collective emotion;(3)a process of reflection is detonated in some individuals from the reading of collective emotions;(4)integration/significance in the community both at the individual and collective level,on the concepts,roles and/or functions that give rise to the process in the system.Therefore,it is clear that emotions play a significant role in the development of cities and these aspects should be considered in the design strategies of all kinds of projects for the city.Future extensions of this work could include a deeper analysis of specific emotional events in urban environments,as well as possible implications for urban policy and decision making.

Number of parous events affects the association between physical exercise and glycemic control among women with gestational diabetes mellitus:A prospective cohort study

Background:Multiparous women are at a higher risk of gestational diabetes mellitus(GDM) than primiparas.Physical activity during pregnancy has been shown to be beneficial for GDM,but there is little evidence on the association between physical activity and glycemic control among women with GDM,whether primiparas or multiparas.Thus,the objective of the present study was to examine the association between physical activity and glycemic control in women with GDM and to determine what,if any,effects result from number of parous events.Methods:A prospective cohort of 1162 women with GDM was recruited,with 604 multiparas(51.98%).The general linear model was used to calculate the risk difference and its 95% confidence interval(95%CI) to quantify the impact of parous events on glycemic control in pregnancy as well as the association between physical activity time and glycemic control.Results:Among 1162 women with GDM,the median daily activity time was 65 mm(interquartile range(IQR):45-90 min),and the abnormal plasma glucose(PG) percentage,calculated as number of abnormal PG tests divided by the total number of PG tests,was 40.00%(IQR:22.22%-66.67%).The percentage of abnormal PG was stabilized and statistically lower with daily physical activity time exceeding 60 min among primiparas(IQR:30.89%-44.43%) and exceeding 90 min among multiparas(ranged from 27.76% to 38.82%).After adjusting for potential confoumders,primiparas tended to have a lower percentage of abnormal PG than do multiparas(rate difference=-0.39,95%CI:-3.61 to2.84).The same amount of physical activity time was significantly less effective for multiparas than for primiparas(trend p-value <0.01).Conclusion:In women with GDM,being multiparous is associated with less effective glycemic control through physical activity,such that multiparas need more physical activity to achieve glycemic control at a similar level to primiparas.

The Influence Factors on Regret Emotion Responsibility and Perceived Control

When people realize or imagine that ＂if you have not taken the same choices as before, the result will be better＂, which kind of experience is called a regret emotion. The purpose of this study is to prove the relationship between regret emotions and a sense of responsibility and control. The results show that the individual＇s sense of responsibility and regret that there is a positive correlation and there is a negative correlation between the control and regret, which is not match the previous part of the study so as to be further explored. At the same time, we found that the regret tendencies in the personality can be explained as some of the regret experiencing in the specific situation. When people realize or imagine that ＂if the choice is not the same as before that things are getting better now＂, they will feel regret.

Potential control of climatic changes on flood events in the Yangtze Delta during1100-2002

Wide collection on the historic records of the climatic changes and flood events is performed in the Yangtze Delta. Man-Kendall (MK) method is applied to explore the changing trends of the time series of the flood discharge and the maximum high summer temperature. The research results indicate that the flood magnitudes increased during the transition from the medieval warm interval into the early Little Ice Age. Fluctuating climate changes of the Little Ice Age characterized by arid climate events followed by the humid and cold climate conditions give rise to the frequent flood hazards. Low-lying terrain made the study region prone to the flood hazards, storm tide and typhoon. MK analysis reveals that the jumping point of the time series of the flood discharge changes occurred in the mid-1960s, that of the maximum summer temperature changes in the mid-1990s, and the exact jump point in 1993. The flood discharge changes are on negative trend before the 1990s, they are on positive tendency after the 1990s; the maximum high summer temperature changes are on negative trend before the 1990s and on positive tendency after the 1990s. These results indicate that the trend of flood discharge matches that of the maximum high summer temperature in the Yangtze Delta. The occurrence probability of the maximum high summer temperature will be increasing under the climatic warming scenario and which will in turn increase the occurrence probability of the flood events. More active solar action epochs and the higher sea surface temperature index (SST index) of the south Pacific Ocean area lying between 4 o N-4 o S and 150 o W-90 o W correspond to increased annual precipitation, flood discharge and occurrence frequency of floods in the Yangtze Delta. This is partly because the intensified solar activities and the higher SST index give rise to accelerated hydrological circulation from ocean surface to the continent, resulting in increased precipitation on the continent.

Emotion recognition and inhibitory control in manifest and pre-manifest Huntington’s disease: evidence from a new Stroop task

Huntington’s disease(HD)is a genetic neurodegenerative disorder that affects not only the motor but also the cognitive domain.In particular,cognitive symptoms such as impaired executive skills and deficits in recognizing other individuals’mental state may emerge many years before the motor symptoms.This study was aimed at testing two cognitive hypotheses suggested by previous research with a new Stroop task created for the purpose:1)the impairment of emotion recognition in HD is moderated by the emotions’valence,and 2)inhibitory control is impaired in HD.Forty manifest and 20 pre-manifest HD patients and their age-and gender-matched controls completed both the traditional“Stroop Color and Word Test”(SCWT)and the newly created“Stroop Emotion Recognition under Word Interference Task”(SERWIT),which consist in 120 photographs of sad,calm,or happy faces with either congruent or incongruent word interference.On the SERWIT,impaired emotion recognition in manifest HD was moderated by emotion type,with deficits being larger in recognizing sadness and calmness than in recognizing happiness,but it was not moderated by stimulus congruency.On the SCWT,six different interference scores yielded as many different patterns of group effects.Overall our results corroborate the hypothesis that impaired emotion recognition in HD is moderated by the emotions’valence,but do not provide evidence for the hypothesis that inhibitory control is impaired in HD.Further research is needed to learn more about the psychological mechanisms underlying the moderating effect of emotional valence on impaired emotion recognition in HD,and to corroborate the hypothesis that the inhibitory processes involved in Stroop tasks are not impaired in HD.Looking beyond this study,the SERWIT promises to make important contributions to disentangling the cognitive and the psychomotor aspects of neurological disorders.The research was approved by the Ethics Committee of the“Istituto Leonarda Vaccari”,Rome on January 24,2018.

Propofol sedation in routine endoscopy:A case series comparing target controlled infusion vs manually controlled bolus concept

BACKGROUND Many studies have addressed safety and effectiveness of non-anaesthesiologist propofol sedation(NAPS)for gastrointestinal(GI)endoscopy Target controlled infusion(TCI)is claimed to provide an optimal sedation regimen by avoiding under-or oversedation.AIM To assess safety and performance of propofol TCI sedation in comparison with nurse-administered bolus-sedation.METHODS Fouty-five patients undergoing endoscopy under TCI propofol sedation were prospectively included from November 2016 to May 2017 and compared to 87 patients retrospectively included that underwent endoscopy with NAPS.Patients were matched for age and endoscopic procedure.We recorded time of sedation and endoscopy,dosage of medication and adverse events.RESULTS There was a significant reduction in dose per time of propofol administered in the TCI group,compared to the NAPS group(8.2±2.7 mg/min vs 9.3±3.4 mg/min;P=0.046).The time needed to provide adequate sedation levels was slightly but significantly lower in the control group(5.3±2.7 min vs 7.7±3.3 min;P<0.001),nonetheless the total endoscopy time was similar in both groups.No differences between TCI and bolus-sedation was observed for mean total-dosage of propofol rate as well as adverse events.CONCLUSION This study indicates that sedation using TCI for GI endoscopy reduces the dose of propofol necessary per minute of endoscopy.This may translate into less adverse events.However,further and randomized trials need to confirm this trend.

Influence of Unconscious Emotional Control Goals Priming on Anticipatory Anxiety and Physiological Activity

Individuals frequently generate emotion during the anticipation process and the anticipatory emotion has an important adaptive significance, especially the negative anticipative emotion. Many researches used conscious emotion regulation strategy and successfully reduced negative anticipatory emotion. However, it is costly for our limited cognition. In the present study, we used sentence unscrambling tasks to prime unconscious emotion control goal and investigated its effect on anticipatory anxiety, including experience and physiological activity. The results showed that 1) relative to anticipating neutral images, participations’ anxiety experience and skin conductance level were higher when anticipating negative and unknown images;2) participants who had a unconscious emotion control goal primed achieved the same decrease in skin conductance as those explicitly instructed to reappraise, compared to a control group;3) heart rate was not affected by experiment condition and anticipation type. Together, these findings suggest that unconscious emotion regulation may provide an effective mean of regulating negative anticipatory emotion.

The History, Trend, Types, and Mitigation of Distributed Denial of Service Attacks

Over time, the world has transformed digitally and there is total dependence on the internet. Many more gadgets are continuously interconnected in the internet ecosystem. This fact has made the Internet a global information source for every being. Despite all this, attacker knowledge by cybercriminals has advanced and resulted in different attack methodologies on the internet and its data stores. This paper will discuss the origin and significance of Denial of Service (DoS) and Distributed Denial of Service (DDoS). These kinds of attacks remain the most effective methods used by the bad guys to cause substantial damage in terms of operational, reputational, and financial damage to organizations globally. These kinds of attacks have hindered network performance and availability. The victim’s network is flooded with massive illegal traffic hence, denying genuine traffic from passing through for authorized users. The paper will explore detection mechanisms, and mitigation techniques for this network threat.

Control Emotion Intensity for LSTM-Based Expressive Speech Synthesis

To improve the performance of human-computer interaction interfaces, emotion is considered to be one of the most important factors. The major objective of expressive speech synthesis is to inject various expressions reflecting different emotions to the synthesized speech. To effectively model and control the emotion, emotion intensity is introduced for expressive speech synthesis model to generate speech conveyed the delicate and complicate emotional states. The system was composed of an emotion analysis module with the goal of extracting control emotion intensity vector and a speech synthesis module responsible for mapping text characters to speech waveform. The proposed continuous variable “perception vector” is a data-driven approach of controlling the model to synthesize speech with different emotion intensities. Compared with the system using a one-hot vector to control emotion intensity, this model using perception vector is able to learn the high-level emotion information from low-level acoustic features. In terms of the model controllability and flexibility, both the objective and subjective evaluations demonstrate perception vector outperforms one-hot vector.

Framework for Preventive Control of Power Systems to Defend Against Extreme Events

Enhancing power system resilience against extreme events is becoming increasingly critical. This paper discusses a unified framework for preventive control of power systems to enhance system resilience, which includes three parts: resilience assessment, resilience grading, and resilience enhancement. First, the resilience assessment contains facility-level and system-level resilience assessment. The concept of fragility curve is used in the facility-level resilience assessment. Various resilience indices are developed in system-level resilience assessment to roundly depict the impacts of extreme events on power systems and determine the system resilience. On this basis, the resilience is divided into different levels by resilience grading strategy, which can efficiently quantify the severity of the impact of extreme events and provide decision-making for the resilience enhancement strategies. Then, control strategies for enhancing power system resilience are also divided according to different resilience levels. A controlled islanding based preventive control is proposed to enhance system resilience, which aims to strengthen the first defensive line of power systems to deal with extreme events. Finally, taking the typhoon disaster in extreme events as an example, two tests carried out with two typhoons demonstrate the efficiency of the proposed method.

Controller Design of DES Petri Nets with Mixed Constraint

The problem of constructing a Petri net feedback controller, which enforces the conjunction of a set of linear inequalities on the reachable marking of the place and transition modeled by Petri net, is discussed. A new method of controller design with mixed constraint is presented, and a net reduction technique of Petri net fuses all the constrained places into one place whose marking is equal to the sum of the markings of the constrained places, and then compared with the constrained transitions. The net reduction eases the design of controller and holds remarkable advantages especially for systems with large scale. The method is proved to be simpler and more efficient than the method presented by Yamalidou, et al, using an applied case used by Yamalidou, et al.

Efficacy and safety of transcutaneous auricular vagus nerve stimulation combined with conventional rehabilitation training in acute stroke patients: a randomized controlled trial conducted for 1 year involving 60 patients

Transcutaneous auricular vagus nerve stimulation(ta-VNS)is a novel noninvasive treat-ment for stroke that directly stimulates the peripheral auricular branch of the vagus nerve.There have been recent reports that ta-VNS combined with conventional rehabilitation training promotes the recovery of neurological function of patients with acute stroke.However,these were small-sample-sized studies on the recovery of neurological function in patients after percutaneous vagus nerve stimulation in the subacute and chronic phases after stroke.This double-blinded randomized controlled trial involved 60 acute ischemic or hemorrhagic stroke patients aged 18-80 years who received treatment in the Second Affiliated Hospital of Chongqing Medical University.The subjects were randomly assigned to receive ta-VNS or sham ta-VNS combined with conventional rehabilitation training.The follow-up results over 1 year revealed that ta-VNS combined with conventional rehabilitation training greatly improved the recovery of motor and sensory functions and emotional responses compared with sham ta-VNS combined with conventional rehabilitation training.There were no obvious side effects.These findings suggest that ta-VNS combined with conventional rehabilitation training for the treatment of acute ischemic or hemorrhagic stroke patients is safe and effective.

Integration of Fault Analysis and Interlock Controller Synthesis for Batch Processes

Integration amongst various decision-making processes, such as planning, design, and operation is necessary to dynamic and flexible batch production. To achieve a batch production integration, utilization of common models used for various decision-making processes is an effective approach. From this point of view, a batch system common model as described by a Petri net is proposed. In this article, a fault diagnosis technique for batch processes is presented using information about fault propagation and the possibilities of integration of fault analysis and controller synthesis are discussed on the basis of the Petri net based common models.

Burstiness-Aware Congestion Control Protocol for Wireless Sensor Networks

In monitoring Wireless Sensor Networks(WSNs),the traffic usually has bursty characteristics when an event occurs.Transient congestion would increase delay and packet loss rate severely,which greatly reduces network performance.To solve this problem,we propose a Burstiness-aware Congestion Control Protocol(BCCP) for wireless sensor networks.In BCCP,the backoff delay is adopted as a congestion indication.Normally,sensor nodes work on contention-based MAC protocol(such as CSMA/CA).However,when congestion occurs,localized TDMA instead of CSMA/CA is embedded into the nodes around the congestion area.Thus,the congestion nodes only deliver their data during their assigned slots to alleviate the contention-caused congestion.Finally,we implement BCCP in our sensor network testbed.The experiment results show that BCCP could detect area congestion in time,and improve the network performance significantly in terms of delay and packet loss rate.

Control of Non-Deterministic Systems With μ-Calculus Specifications Using Quotienting

The supervisory control problem for discrete event system(DES) under control involves identifying the supervisor, if one exists, which, when synchronously composed with the DES,results in a system that conforms to the control specification. In this context, we consider a non-deterministic DES under complete observation and control specification expressed in action-based propositional μ-calculus. The key to our solution is the process of quotienting the control specification against the plan resulting in a new μ-calculus formula such that a model for the formula is the supervisor. Thus the task of control synthesis is reduced a problem of μ-calculus satisfiability. In contrast to the existing μ-calculus quotienting-based techniques that are developed in deterministic setting, our quotienting rules can handle nondeterminism in the plant models. Another distinguishing feature of our technique is that while existing techniques use a separate μ-calculus formula to describe the controllability constraint(that uncontrollable events of plants are never disabled by a supervisor), we absorb this constraint as part of quotienting which allows us to directly capture more general state-dependent controllability constraints. Finally, we develop a tableau-based technique for verifying satisfiability of quotiented formula and model generation. The runtime for the technique is exponential in terms of the size of the plan and the control specification. A better complexity result that is polynomial to plant size and exponential to specification size is obtained when the controllability property is state-independent. A prototype implementation in a tabled logic programming language as well as some experimental results are presented.

Research on Distributed Cooperative Control Strategy of Microgrid Hybrid Energy Storage Based on Adaptive Event Triggering

Distributed collaborative control strategies for microgrids often use periodic time to trigger communication,which is likely to enhance the burden of communication and increase the frequency of controller updates,leading to greater waste of communication resources.In response to this problem,a distributed cooperative control strategy triggered by an adaptive event is proposed.By introducing an adaptive event triggering mechanism in the distributed controller,the triggering parameters are dynamically adjusted so that the distributed controller can communicate only at a certain time,the communication pressure is reduced,and the DC bus voltage deviation is effectively reduced,at the same time,the accuracy of power distribution is improved.The MATLAB/Simulink modeling and simulation results prove the correctness and effectiveness of the proposed control strategy.

Characteristics of Xiao Chai Hu decoction based on randomized controlled trials: A bibliometric analysis

Objective:To explore the characteristics of Xiao Chai Hu(XCH)decoction in randomized controlled trials(RCTs)using a bibliometric method.Methods:Seven databases including PubMed,Web of Science,Embase,Cochrane library,China National Knowledge Infrastructure(CNKI),Chinese Scientific Journal Database(VIP)and Wanfang database were retrieved from inception to May 27,2022.In the study,XCH decoction(or modified)used alone or combined with conventional Western medicine as an intervention measure was included.The basic characteristics,funding support,relevant diseases,intervention methods,and adverse events(AEs)were analyzed.Data analysis was performed using SPSS 26.0 software.Results:A total of 813 RCTs were included,published from 1989 to 2022.There was only one Englishlanguage literature with the recent impact factor of 5.374.There were 147 studies were from Chineselanguage core journals,with the highest impact factor of 2.414.Only 6.15%of the literatures mentioned funding support.96.31%of the included literature reported the statistical significance of using XCH decoction.The diseases treated mainly included chronic hepatitis B(9.35%),cough variant asthma(5.66%),dizziness(5.54%),bile reflux gastritis(4.43%),and fever(4.18%).However,the overall research design of the included literature was poor,and large sample size,multicenter RCTs are needed.The incidence of AEs of XCH decoction alone was 8.86%,which was significantly lower than that of conventional Western medicine treatment.The combination of XCH decoction and conventional Western medicine treatment could reduce the incidence of AEs,and no serious adverse event was reported.Conclusion:Although the included studies show that XCH decoction is widely used,and has good efficacy and few AEs.Due to the low quality of the included RCTs,there may be some bias,and its rational use based on the specific conditions is recommended in clinical practice.

Chinese emotional words in patients with major depressive disorder during a subliminal Stroop task An event-related potential study

Patients with major depressive disorder （MDD） develop a negative cognitive bias, but how they respond to information in Chinese emotional words is unclear. Here we used a Stroop paradigm with subliminal Chinese emotional words to explore the event-related potential components of abnormal emotional processing Jn patients with MDD. The correct rate was similar in MDD and normal control groups, but MDD reaction time was longer than the normal controls, especially to the negative and neutral stimuli. In N270, repeated-measure analysis of variance demonstrated a significant main effect of the relation electrode and valence on peak amplitude and interactions between valence and electrode site. The peak amplitudes of the three kinds of words were different in the two groups （positive 〉 negative 〉 neutral）. The topography of the difference waves indicated that the difference distributed in the frontal and left parietal-temporal sites across the scalp. In N400, there was a significant main effect of the relation electrode and valence on peak amplitude, and the latency showed a main effect of the electrode and an interaction between electrode and group. The amplitudes induced by type of words were significantly different from each other in both groups （positive 〉 negative 〉 neutral）. The topography of the difference waves indicated that the effect of relation type was primarily at left and right frontal and central and left parietal-temporal regions. Both MDD patients and normal controls exhibited significant emotional Stroop effects during the processing of positive/negative Chinese emotional words. MDD patients showed interference in emotional stimuli in early cognitive processing that induced psychological resource intervention during late emotional information processing.
