Canton Fair:Foreign Trade Enterprises Fight Against Difficulties

The 110th Chinese Export Commodities Fair, also called Canton Fair, was held in Pazhou International Exhibition Center in October this year which marks the tenth anniversary of China’s accession to the WTO. China’s foreign trade enterprises are facing a grim situation

The 98th Canton Fair Ended with Ample Fruits

Three countries and areas take a leading role in the transaction.The top three are the European Union(EU),the Middle East and the USA,the transaction amounts were respectively US$2.32 billion,US$931 billion and US$927 million.

A Pragmatics Analysis on Cross-cultural Business Negotiation——Based on Canton Fair Cases

Accurate and appropriate pragmatics strategies play a significant role in cross-cultural business negotiation between exhibitors and buyers.Through the analysis of cross-cultural business negotiation dialogue between exhibitors and buyers in Canton Fair Cases,pragmatics strategies,on the basis of Cooperative Principle,Politeness Principle and Face Theory,can be obtained as follows.When negotiating over product,although Cooperative Principle is expected to be followed,exhibitors are more likely to break it and thus buyers are supposed to identify the authenticity of exhibitors'presentations.When negotiating over quote,both ex-hibitors and buyers are more likely to flout Cooperative Principle under some circumstances and therefore they should follow Politeness Principle and care of the other's face for win-win cooperation.

To Witness the Development of Canton Fair

Chinese import and export commodities fair,also called Canton Fair,founded in the spring of 1957,is a comprehensive international trade and commercial event with the longest history,the highest level,the largest scale,the most types of goods,the most complete varieties,whose high reputation attracts buyers from all over the world to purchase

A Formal Model for Analyzing Fair Exchange Protocols Based on Event Logic

Fair exchange protocols play a critical role in enabling two distrustful entities to conduct electronic data exchanges in a fair and secure manner.These protocols are widely used in electronic payment systems and electronic contract signing,ensuring the reliability and security of network transactions.In order to address the limitations of current research methods and enhance the analytical capabilities for fair exchange protocols,this paper proposes a formal model for analyzing such protocols.The proposed model begins with a thorough analysis of fair exchange protocols,followed by the formal definition of fairness.This definition accurately captures the inherent requirements of fair exchange protocols.Building upon event logic,the model incorporates the time factor into predicates and introduces knowledge set axioms.This enhancement empowers the improved logic to effectively describe the state and knowledge of protocol participants at different time points,facilitating reasoning about their acquired knowledge.To maximize the intruder’s capabilities,channel errors are translated into the behaviors of the intruder.The participants are further categorized into honest participants and malicious participants,enabling a comprehensive evaluation of the intruder’s potential impact.By employing a typical fair exchange protocol as an illustrative example,this paper demonstrates the detailed steps of utilizing the proposed model for protocol analysis.The entire process of protocol execution under attack scenarios is presented,shedding light on the underlying reasons for the attacks and proposing corresponding countermeasures.The developedmodel enhances the ability to reason about and evaluate the security properties of fair exchange protocols,thereby contributing to the advancement of secure network transactions.

Canton Fair:not so Satisfactory

During the past years, it is just through the Canton Fair, China has been reputed as the World Apparel Processing Factory. However, after the busy Canton Fair this year, textile and apparel exhibitors have suffered unheard-of chill markedly, just like the unexpected cold winter in Guangdong Province in early 2008.

Trading in the Cloud The first online Canton Fair brings new impetus to Sino-African trade ties

The China Import and Export Fair, also known as the Canton Fair, is China’s oldest trade fair. It is also the largest, as it covers an area equivalent to 166 football pitches. Due to the COVID-19 pandemic, the 127 th edition of this biannual trade fair was held online from June 15 to 24 for the first time since its creation in 1957.

Aerodynamic Analysis and Optimization of Pantograph Streamline Fairing for High-Speed Trains

A pantograph serves as a vital device for the collection of electricity in trains.However,its aerodynamic resistance can limit the train’s running speed.As installing fairings around the pantograph is known to effectively reduce the resistance,in this study,different fairing lengths are considered and the related aerodynamic performances of pantograph are assessed.In particular,this is accomplished through numerical simulations based on the k-ωShear Stress Transport(SST)two-equation turbulence model.The results indicate that the fairing diminishes the direct impact of high-speed airflow on the pantograph,thereby reducing its aerodynamic resistance.However,it also induces interferences in the flow field around the train,leading to variations in the aerodynamic resistance and lift of train components.It is shown that a maximum reduction of 56.52%in pantograph aerodynamic resistance and a peak decrease of 3.38%in total train aerodynamic resistance can be achieved.

Ada-FFL:Adaptive computing fairness federated learning

As the scale of federated learning expands,solving the Non-IID data problem of federated learning has become a key challenge of interest.Most existing solutions generally aim to solve the overall performance improvement of all clients;however,the overall performance improvement often sacrifices the performance of certain clients,such as clients with less data.Ignoring fairness may greatly reduce the willingness of some clients to participate in federated learning.In order to solve the above problem,the authors propose Ada-FFL,an adaptive fairness federated aggregation learning algorithm,which can dynamically adjust the fairness coefficient according to the update of the local models,ensuring the convergence performance of the global model and the fairness between federated learning clients.By integrating coarse-grained and fine-grained equity solutions,the authors evaluate the deviation of local models by considering both global equity and individual equity,then the weight ratio will be dynamically allocated for each client based on the evaluated deviation value,which can ensure that the update differences of local models are fully considered in each round of training.Finally,by combining a regularisation term to limit the local model update to be closer to the global model,the sensitivity of the model to input perturbations can be reduced,and the generalisation ability of the global model can be improved.Through numerous experiments on several federal data sets,the authors show that our method has more advantages in convergence effect and fairness than the existing baselines.

Dilemmas and Optimization of Third-Party Assessment System in Chinese Fair Competition Review

The current predominant self-review mechanism by policy-making bodies suffers from deficiencies such as insufficient motivations, limited review capabilities, and weak external supervision. Third-party assessment, characterized by independence and specialization, is designed to mitigate these shortcomings. However, the implementation of third-party assessment faces challenges too. This paper intends to improve the third-party assessment system and to realize the legislative purpose of the system. Based on social research, discussions and exchanges with relevant parties, and the existing research results, this paper analyzes the challenges and possible optimization measures for the third-party assessment. The challenges include repulsion from policy-making bodies, insufficient independence of assessment bodies, disparity of assessment quality, and limited application of assessment outcomes. Possible optimization measures include promoting fair competition culture, increasing the acceptance of third-party assessment from policy-making bodies, enhancing the quality of third-party assessment, clarifying the relationship between policy-making bodies and assessment bodies, ensuring the independence of third-party assessments, and promoting the application of assessment results.
