Matsunchi, who also proposed one class of the nonlinear Schrdinger equation system with wave operator. We also obtain the same type of equations, which are satisfied by transverse velocity of higher frequency electron, as we study soliton in plasma physics. In this paper, under some condition we study the existence and nonexistence for this equations in the cases possessing different signs in nonlinear term. 展开更多

The author considers the global existence and global nonexistence of the initial-boundary value problem for some degenerate hyperbolic equation of the form utt- div(|△↓|^P-2 △↓u)=|u|^m u, (x,t)∈[0, +∞) ×Ω with p 〉 2 and m 〉 0. He deals with the global solutions by D.H.Sattinger's potential well ideas. At the same time, when the initial energy is positive, but appropriately bounded, the global nonexistence of solutions is verified by using the analysis method. 展开更多

At present,the West overrides the east in international human rights discourse.In order to break through the shackles,it is imperative to provide legal support for China’s human rights discourse.taking the concept of“human existence”as the fulcrum and comparing it with nature,otherness,and community as the reference,the human being showcases triple facets:“individual person”,“person in relations”,and“person with rights”,which correspond to the three personal perspectives and progressively deduce the subjectivity of human beings,the world history of human rights,and the comprehensive and free development of human rights discourse.the concept of“individual person”is the starting point of human rights,and the harmonious,moral concept of subjectivity provides an orderly basis for the importance of the“right to subsistence and right to development”.“person in relations”represents the externality of human rights,and the world-historical view of time and space has laid the value foundation for the unity of“universality and particularity of human rights”.“person with rights”is the goal of human rights,and the concept of cooperation for the well-rounded and free development of human rights paves the conceptual way for the realization of people’s well-being. 展开更多

Human rights are of great concern to the international community, as they focus on the survival of all people and people’s right to development. The right to life is a prerequisite for the right to development. For countries of the Global South, the right to life is fundamental to development. Thus the Belt and Road Initiative put forward by the Chinese government in 2013 presents opportunities for the human rights development of Global South countries. However, several factors such as the large poverty-stricken populations, economic backwardness, and the cultural difference present challenges to the promotion of human rights ideology and culture. South-South Countries should strive to address this challenge by eliminating poverty, and strengthening communication and cooperation with developed countries promoting inter-cultural exchanges, and finally promoting South-South human rights development cooperation. 展开更多

In his short story collection Lost in the Funhouse, John Barth attempts to deal with the existential plights that fictional writing and human beings are faced with."Title", the most postmodern story in the collection, centers on the issue of"filling in the blank,"in which Barth leads readers to solve the problem and create the story with him. To examine Barth's postmodern experiment in"Title", this paper mainly focuses on the following three questions: what is the"blank"? How to fill in it? Why to fill in it in that way? By answering them, we may see how Barth reconciles the conflict between the urgency of"filling in the blank"and the failure of filling them. 展开更多

First, we obtain the existence of local Wkp solutions. Then, we prove that, if f(s) ∈ Ck+1(R) is nondecreasing, f(0) = 0 and |f(u)| ≤ C1|u|∫0uf(s)ds + C2, u0(x),u1(x) ∈ WkP(Ω) ∩ W01,P(Ω), k≥ 1, 1 〈 p≤ ∞, then for any T 〉 0 the problem admits a unique solution u(x, t) ∈ W2,∞(0, T; WkP(Ω) ∩ W01,P(Ω)). Finally, the finite time blow-up of solutions and global Wkp solution of generalized IMBo equations are discussed. 展开更多

This paper is a continue work of [4, 5]. In the previous two papers, we studied the Cauchy problem of the multi-dimensional compressible Euler equations with time-depending damping term --u/(1+t)λpu, where λ≥ 0 and μ 〉 0 are constants. We have showed that, for all λ ≥ 0 andμ 〉 0 the smooth solution to the Cauchy problem exists globally or blows up in finite time. In the present paper, instead of the Cauchy problem we consider the initial- boundary value problem in the half space R+^d with space dimension d = 2, 3. With the help of the special structure of the equations and the fluid vorticity, we overcome the difficulty arisen from the boundary effect. We prove that there exists a global smooth solution for 0 ≤λ 〈 1 when the initial data is close to its equilibrium state. In addition, exponential decay of the fluid vorticity will also be established. 展开更多

The liberation of women is the historical process in which women have striven for gender equality, freedom from oppression, confinement and discrimination, and are becoming the masters of the society and their own destinies. According to the diversity in history and the state, the process can be divided into a serial of correlated phases, with each phase focusing on different issues. Sexism order in China had remained stable in the traditional society for centuries through a set of institutions. Women had believed in a sexual order and the rules of propriety, which advocated that men were superior to women. After the People’s Republic of China was founded in 1949, women’s rights in politics, economy, society, and even family were recognized and secured by the Constitution and laws just as men’s during a short period. Women’s liberation in China has made a significant progress. 展开更多

Animals must strike a balance between anti-predation behavior and other essential behaviors,such as foraging.Within the same species,strategies may vary on individuals’risk-taking preferences,and in this process the environment is a determinant,in addition to predator regime.The Crested Ibis(Nipponia nippon)exhibits such tendency.This is an endangered species,once inhabiting exclusively in China’s Qinling Mountain.This used to be the sole remaining wild population.However,over recent decades,this population has expanded.A portion has relocated to breed in the lower plain area,which is characterized by elevated level of human activities and landscape complexity.We used flight initiation distance(FID)as an indicator of the ibises’risk-taking preference,particularly their response to human proximity.Additionally,we examined the environmental factors influencing their foraging site selection,including altitude,terrain openness,human activity intensity and human construction.Our findings revealed a significantly shorter FID among individuals relocating to plain habitats,indicating a higher tolerance of human proximity.The results showed that FID decreased with distance to the nearest human settlement.Another finding is that FID was independent of instant human activity intensity and environmental factors(altitude and terrain openness).These different may arise from various combinations of human activity,predation risk,and food abundance within the two habitats.These results provide insights into the in situ conservation of the threatened species within the context of global urbanization. 展开更多

Interpreting the Universal Declaration of Human Rights from political,juridical and philosophical perspectives is es-sential for promoting the guiding principles of the Declaration,build-ing consensus on human rights,and advancing human rights practice in the new historical context.To conduct an academic,systematic in-terpretation of the Declaration that conforms to the trends of the times and answers the fundamental questions of the world,it is necessary to find a new research paradigm.The common values of humanity,namely peace,development,equity,justice,democracy and freedom,put forward by Xi Jinping,general secretary of the Communist Party of China(CPC)Central Committee,provide the most explanatory and penetrating scientific paradigm for reaching the issue.This paper an-alyzes and reflects on the views,value foundation and principled(con-tractual)consensus of human rights in the Declaration,and narrates and foresees the far-reaching significance of the three global initia-tives(namely,the Global Development Initiative,the Global Security Initiative,and the Global Civilization Initiative)with the common val-ues of humanity as the soul in advancing the modernization of global human rights governance and building a new form of human rights civilization. 展开更多

In fluid mechanics and astrophysics,relativistic Euler equations can be used to describe the effects of special relativity which are an extension of the classical Euler equations.In this paper,we will consider the initial value problem of relativistic Euler equations in an initial bounded region of R N.If the initial velocity satisfies max→x 0∈∂Ω(0)N∑i=1 v_(i)^(2)(0,→x 0)<c^(2)A_(1)/2,where A 1 is a positive constant depend on some sufficiently large T^(*),then we can get the non-global existence of the regular solution for the N-dimensional relativistic Euler equations. 展开更多

Objective To analyze the relationship between malignant transformation and abnormal expression of eukaryotic initiation factor 3 (eIF3 p36) in human bronchial epithelial (16HBE) cells induced by cadmium chloride (CdCl2). Methods 16HBE cells were treated several times with different concentrations of CdCl2. Tumorigenic potential of transformed cells was identified by assays for anchorage-independent growth in soft agar and for tumorigenicity in nude mice after the 35th passage. Total RNA was isolated from 16HBE cells induced by CdC12, including non-transformed, Cd-transformed, and Cd-tumorigenic cell lines. Special primers for eIF3 p36 were designed and the expression of eIF3 mRNA in different cell lines was detected with fluorescent quantitative-polymerase chain reaction technique (FQ-PCR). Results The 35th passage of 16HBE cells transformed by CdCl2 exhibited overlapping growth. Compared with the non-transformed cells, colonies of transformed cell lines in soft agar showed statistically significant increases and dose-dependent effects (P〈0.01). All Cd-induced transformed cell lines formed rumors in nude mice within 2 weeks of inoculation, but none of the mice injected with non-transformed cells showed tumors even after 3 weeks. All tumors were pathologically identified as poorly differentiated squamous cell carcinoma. The eIF3 p36 genes in different stages of 16HBE cells transformed by CdCl2 were elevated as compared with the non-transformed control (P〈0.01), and the eIF3 expression increased with the degree of cell malignancy. Conclusion CdCl2 is capable of inducing morphological transformation in 16HBE cells and transformed cells are potentially tumorigenic. Over-expression of eIF3 p36 is positively correlated with malignant transformation of 16HBE cells induced by CdCl2 and may be one of the molecular mechanisms potentially responsible for carcinogenesis due to Cd. 展开更多
