Quantum dialogue(QD)enables two communication parties to directly exchange secret messages simultaneously.In conventional QD protocols,photons need to transmit in the quantum channel for two rounds.In this paper,we propose a one-step QD protocol based on the hyperentanglement.With the help of the non-local hyperentanglement-assisted Bell state measurement(BSM),the photons only need to transmit in the quantum channel once.We prove that our one-step QD protocol is secure in theory and numerically simulate its secret message capacity under practical experimental condition.Compared with previous QD protocols,the one-step QD protocol can effectively simplify the experiment operations and reduce the message loss caused by the photon transmission loss.Meanwhile,the non-local hyperentanglement-assisted BSM has a success probability of 100%and is feasible with linear optical elements.Moreover,combined with the hyperentanglement heralded amplification and purification,our protocol is possible to realize long-distance one-step QD. 展开更多

This paper explores the Major National Dialogue organised by Paul Biya from the 30th of September to the 4th of October,2019 as a panacea to the Anglophone.The paper also seeks to find out if this dialogue has been the panacea Cameroonians as a whole and the people of Southern Cameroons in particular have been waiting for to end this conflict.This research uses a qualitative research design.This is because the researcher culled information from Jeune Afrique Economie(2019a),Cameroon Tribune,and from Phoenix.Descriptive analysis was used to analyse the collected data.Descriptive analysis is used to get the views of the public whether the Major National Dialogue was really a panacea to the Anglophone crisis.The analysis revealed that there were two opposing opinions on the holding of this dialogue.The government thinks the dialogue was a panacea to put an end to this crisis because there is ongoing construction work in the war zones,and economic activities have witnessed an increase in the regions as the various production units of the Cameroon Development Corporation(CDC)and Pamol plantations have regained agricultural activities.The Ndawara tea estate now functions without problems.Trans-border trade is on the rise and transportation is fluid,except in the rural areas where the state of the road network is poor to name but these.On the other hand,politicians,political parties like the Social Democratic Front,activists,religious leaders,the affected populations,and Cameroonians at large think that the Major National Dialogue was a monologue and therefore was bound to fail because first,key actors arrested and detained in connection to this crisis were not part of this dialogue.For this reason,they are calling for a genuine and an inclusive dialogue.In addition,they argue that we cannot be talking of peace when fighting is still raging on and people are being killed,houses and schools are being burnt,and people are being kidnapped every day for ransom to mention but these. 展开更多

At the end of the Ming Dynasty and at the beginning of the Qing Dynasty,a new theory of learning was created-Muslim Confucian Study(Chinese Islamic Philosophy)-on the basis of Islamic philosophy and under the influence of Confucianism.Wang Daiyu(1570-1660)and Liu Zhi(1660-1739)were two great Huiru(Muslim Confucian)scholars at that time.They published Zhengjiao zhenquan(The real commentary on the tire teaching),Tianfang xingli(Nature and principle in Islam)major books.Their approach is distinguished from that of other Muslim scholars in that they addressed the basic articles of Islamic thought with Confucian terminology and categories.The study deals with the Islamic worldview,and with the practices that make it possible for people to bring themselves into conformity with that worldview.However,the teaching of the Muslim Confucian was continuous with those of Mainstream Islam.In my research,I attempted to answer two questions:(a)How did Muslim Confucian Study Inherit the Mainstream Islamic Thought?(b)What is the value and contribution of the World Islamic philology and civilization? 展开更多

In this paper a quantum dialogue scheme is proposed by using N batches of single photons. The same secret message is encoded on each batch of single photons by the sender with two different unitary operations, and then the N batches of single photons are sent to the receiver. After eavesdropping check, the message is encoded on the one remaining batch by the receiver. It is shown that the intercept-and-resend attack and coupling auxiliary modes attack can be resisted more efficiently, because the photons are sent only once in our quantum dialogue scheme. 展开更多

Quantum system is inevitably affected by the external environment in the real world.Two controlled quantum dialogue protocols are put forward based on logicalχ-type states under collective noise environment.One is against collectivedephasing noise,while the other is against collective-rotation noise.Compared with existing protocols,there exist several outstanding advantages in our proposed protocols:Firstly,theχ-type state is utilized as quantum channels,it possesses better entanglement properties than GHZ state,W state as well as cluster state,which make it difficult to be destroyed by local operations.Secondly,two kinds of logicalχ-type states are constructed by us in theory,which can be perfectly immune to the effects of collective noise.Thirdly,the controller can be offline after quantum distribution and permission announcement,without waiting for all the participants to complete the information coding.Fourthly,the security analysis illuminates that our protocols can not only be free from the information leakage,but also resist against the interceptand-resend attack,the entanglement-and-measure attack,the modification attack,the conspiring attack,and especially the dishonest controller’s attacks. 展开更多

The link between chronic inflammation and colorectal cancer has been well established. The events proceeding along tumorigenesis are complicated and involve cells activated at the cancer microenvironment, tumor infiltrating polymorphonuclears, immune cells including lymphocyte subtypes and peripheral blood mononuclear cells(PBMC), as well as tumor-associated macrophages. The immune cells generate inflammatory cytokines, several of them playing a crucial role in tumorigenesis. Additional factors, such as gene expression regulated by cytokines, assembling of tumor growth- and transforming factors, accelerated angiogenesis, delayed apoptosis, contribute all to initiation, development and migration of tumor cells. Oxygen radical species originating from the inflammatory area promote cell mutation and cancer proliferation. Tumor cells may over-express pro-inflammatory mediators that in turn activate immune cells for inflammatory cytokines production. Consequently, an immune dialogue emerges between immune and cancer cells orchestrated through a number of activated molecular pathways. Cytokines, encompassing migration inhibitory factor, transforming growth factor beta 1, tumor necrosisfactor-α, Interleukin(IL)-6, IL-10, IL-12, IL-17, IL-23 have been reported to be involved in human cancer development. Some cytokines, namely IL-5, IL-6, IL-10, IL-22 and growth factors promote tumor development and metastasis, and inhibit apoptosis via activation of signal transducer activator transcription-3 transcription factor. Colon cancer environment comprises mesenchymal, endothelial and immune cells. Assessment of the interaction between components in the tumor environment and malignant cells requires a reconsideration of a few topics elucidating the role of chronic inflammation in carcinogenesis, the function of the immune cells expressed by inflammatory cytokine production, the immunomodulation of cancer cells and the existence of a cross-talk between immune and malignant cells leading to a balance in cytokine production. It is conceivable that the prevalence of anti-inflammatory cytokine production by PBMC in the affected colonic mucosa will contribute to the delay, or even to halt down malignant expansion. Targeting the interplay between immune and cancer cells by mediators capable to alter cytokine secretion toward increased anti-inflammatory cytokine release by PBMC and tumor associated macrophages, may serve as an additional strategy for treatment of malignant diseases. This review will focus on the inflammatory events preceding tumorigenesis in general, and on a number of modulators capable to affect colon cancer cell-induced production of inflammatory cytokines by PBMC through alteration of the immune crosstalk between PBMC and cancer cells. 展开更多

Teacher-student collaborative assessment(TSCA)aims to address the challenges of responding to students’work in the Production-Oriented Approach:low efficiency and poor effectiveness.As part of a bigger project carried out in a Chinese university over a period of three years,the present study explored how the teacher prepared and implemented TSCA in class,especially with a focus on how she determined the assessing objective and worked collaboratively with her students in class to achieve it,using the students’written and translated texts as examples.By adopting the dialectical research(DR)method,this paper collected qualitative data such as teaching plans,classroom recordings,and reflective journals of the teacher-researcher(the author),along with students’written drafts and translated texts.TSCA theory and classroom practice have been refined simultaneously by means of putting theory into practice and reflecting upon it.The optimized pre-class and in-class procedures may shed some light on applying TSCA to L2 classrooms. 展开更多

A protocol for quantum dialogue is proposed to exchange directly the communicator's secret messages by using a three-dimensional Bell state and a two-dimensional Bell state as quantum channel with quantum superdence coding, local collective unitary operations, and entanglement swapping. In this protocol, during the process of trans- mission of particles, the transmitted particles do not carry any secret messages and are transmitted only one time. The protocol has higher source capacity than protocols using symmetric two-dimensional states. The security is ensured by the unitary operations randomly performed on all checking groups before the particle sequence is transmitted and the application of entanglement swapping. 展开更多
