Two electron and two hole surface channels are simultaneously present in all channel current ranges. Output and transfer characteristics are computed over practical base and gate oxide thicknesses. The bipolar theory corroborates well with experimental data reported recently for FinFETs with metal/silicon and p/n junction source/drain contacts. Single-device realization of CMOS inverter and SRAM memory circuit functions are recognized.展开更多

Due to its crucial positive external effects, it is inevitable policy that non-commercial forestry should be invested by government, thereby formulates the non-commercial forestry compensation system. This paper first discusses the theoretical basis of non-commercial forestry compensation system and the process of establishment of non-commercial forestry compensation system in China, and then analyzes the deficiency in the current compensation system.展开更多

The autonomy of each unit was investigated in this foundation. The system unit was described using the Web Ontology Language (OWL) ontology. And the system semantics was also integrated. On these basics the communication among the system units was analyzed with an example of interaction between a machine and a warehouse. The control performances of information system units were investigated using Boolean matrix as a substitute for traditional process in RW theory, which reduced the computational complexity. This work established the foundation for the demand analysis, design and development of the distributed manufacture information system.展开更多

Secondly, it is to bring the irreducibility of the teleological to non-teleological into organic development to unprecedented light so as to show how the ontological predominance of the finality over the material necessity may be adequately expressed by a logical implication, if it is appropriately stated and well distinct from other similar logical connectives such as the material implication and the biconditional if-and-only-if.展开更多

The introduction of Practice Ontology Aesthetics occurred in the course of introspection of Practice Aesthetics in modem China, in which the existence dimension in Marxist concept of practice was of great significance to breaking the theoretical limitation of present Practice Aesthetics. Therefore, in terms of the distinctive context of Chinese contemporary aesthetics, the introduction of Practice Ontology Aesthetics from the theoretical perspective of Marxist existentialism offers a possible way to break the current aesthetics and represents a multiple academic pursuit of Marxist, Chinese and modem aesthetics.展开更多
"Emotion is a specific manner of apprehending the world" and transforming the world rather than an "accidental modification of a subject who is surrounded by an unchanged world," according to Jean-Paul Sartre. Bot..."Emotion is a specific manner of apprehending the world" and transforming the world rather than an "accidental modification of a subject who is surrounded by an unchanged world," according to Jean-Paul Sartre. Both Sketch for a Theory of the Emotions and Being and Nothingness set out to investigate these relationships in broadly two ways. One, consciousness of the world of others is experienced through our emotions (anger, fear, shame, and pride for instance) as a body that escapes our grasp in being-seen-by-another. Two, we apprehend the world through our emotions in the process of magical transformation (for example, fear, melancholy, and sadness). This paper examines emotions on two levels: how we experience our ontological state as being-for-itself-in-itself and being-in-the-world-for-others; and how we conceive emotions as "magic" changing its relationship with the world "so that the world should change its qualities." What is of critical interest here is the relationship between consciousness and emotions. Situating this discussion in the context of Satre's critique on psychology, it proceeds to advance his existential psychoanalysis, starting with establishing a place for emotions and concluding with its transformative power to escape their situations.展开更多

History is not an ideology. History cannot be ended, if by history we mean the past, which we remember and interpret for the purpose of orientating ourselves in the present and the future. Fukuyama has a right to declare the victory of liberal democracy, but other political ideologies have not become extinct. If we look at the thesis of the "end of history" from a scientific point of view, then we can conclude that such a thing is impossible: for after the "end of history", history continues. Therefore, there is no real end to history. It is continuing a quarter of a century after the Fukyama's thesis was published. Even if we can accept the thesis of the end of history as an ideology, we still cannot accept the end of philosophy. Phenomenology, Critical Realism, Existentialist Philosophy Hermeneutics, Structuralism, etc. are just some of the evidence that contemporary philosophy continues to exist and evolve despite the rising and falling of various ideologies in the twentieth century and the early twenty-first century. This can also be said about art, culture, and history as a science展开更多

The "material" in historical materialism is a social thing which is "perceptible and imperceptible by the senses" and connotes social relations; and the "history" in historical materialism is the realm in which contradictions between man and nature and between man and society are able to unfold, so historical materialism is "actually a critical view of the world" that inherently contains dialectics in a "rational form." The formulation of historical materialism opened a new path for the development of materialism and even philosophy as a whole. In the course of its critique of capitalist society, which unfolds with capital as a core category, historical materialism sublates abstract existence and discovers real social existence, thus putting an end to metaphysics, which is grounded in abstract ontology.展开更多

Our operator is of the most general form containing all previous ones and we also weaken assumptions on the operator and the nonlinearity to get the above results. Moreover, we do not impose the restricted condition on p(x) and the uniform monotonicity of the operator to show the existence of three distinct solutions.展开更多

The authors also investigate a related nonlinear eigenvalue problem obtaining an existence result which contains information about the location and multiplicity of eigensolutions. The proofs of the main results are obtained by using the critical point theory in Sobolev weighted spaces combined with a Caffarelli-Kohn-Nirenberg-type inequality and by using a specific minimax method, but without making use of the Palais-Smale condition.展开更多
