Philosophy of zero: Zero and its Interactions; O-rigin of 0 and 1. Consciousness: Classification of Consciousness: Consciousness of Stones, Conscious ness of Amoeba, Consciousness of Man, Conscious ness of Angels, Consciousness of God (Monadism of Leibniz). Relations between Man and Consciousness: Logical, birth of Logic, i.e. Deduction, discovered in Greece and perfected by Aristotle. Quantitative, birth of numbers, discovered by Arabians. Discovery of 0, the greatest World Mathematician, supposed to be the Hindus, mentioned by Bramagupta. Birth of Interac tions: Example: Interaction of 0 and 0: 0 + 0, 0 - 0, 0x0,0-^0, the last term indefinite, birth of something new. Discoverer of the Calculus is Newton. Besides, he discovered Universal Gravitation. Interaction of and 2: 1 Absolute; 2 Relative. Relativeness + Universal Gravitation = birth of Einstein's Relativity. Which is greater, Einstein or Newton? Answer: Einstein is greater since he discovered both Relativity and Quantum Theory which changed our entire view of the universe.

Two multiparty simultaneous quantum identity authentication (MSQIA) protocols based on secret sharing are presented. All the users can be authenticated by a trusted third party (TTP) simultaneously. In the first protocol,the TTP shares a random key K with all the users using quantum secret sharing. The ith share acts as the authentication key of the ith user. When it is necessary to perform MSQIA,the TTP generates a random number R secretly and sends a sequence of single photons encoded with K and R to all the users. According to his share,each user performs the corresponding unitary operations on the single photon sequence sequentially. At last,the TTP can judge whether the impersonator exists. The sec-ond protocol is a modified version with a circular structure. The two protocols can be efficiently used for MSQIA in a network. They are feasible with current technol-ogy.

An approach to inspecting massive numbers of moving seeds was studied based on the techniques of dynamic inspection and machine vision. A progressive scanning CCD camera with external trigger function was used for real-time capture of dynamic images of seeds. The methods based on R channel of RGB (Red, Green and Blue) and region-dependent segmentation were adopted to reduce the data size of image processing and improve the efficiency of seeds inspection. All the seeds were sorted into four grades according to their morphological characteristics, such as surface area, perimeter, major axis, minor axis, circularity and eccentricity. The detection experiments indicated that the eligible ratio of the classifications was about 81.90% by this real-time inspection system.

Using a small quantity of DNA molecules and little experimental time to solve complex problems successfully is a goal of DNA computing. Some NP-hard problems have been solved by DNA computing with lower time complexity than conventional computing. However, this advantage often brings higher space complexity and needs a large number of DNA encoding molecules. One example is graph coloring problem. Current DNA algorithms need exponentially increasing DNA encoding strands with the growing of problem size. Here we propose a new DNA algorithm of graph coloring problem based on the proof of four-color theorem. This algorithm has good properties of needing a relatively small number of operations in polynomial time and needing a small number of DNA encoding molecules (we need only 6R DNA encoding molecules if the number of regions in a graph is R).

Statistical analysis was conducted on sow stillbirth traits of three mating types with 1686 litters including Erhualian, Large White and F1. The number of stillborn piglets per litter (NSB) in Erhualian, Large White and F1 averaged 0.87, 0.3., 0.72, and the percentage born alive (PBA) averaged 95.1%, 97.1% , 95.7% , respectively. The Erhualian pig with a higher litter size also had a higher stillbirth rate. The results of the variance analysis indicated that the mating type, parity, farrowing year X farrowing season interaction and the total number born had highly significant effects on both NSB and PBA in sows (P 0.05), and highly significant effects on PBA (P 3. the genetic correlation, phenotypic correlation and environmental correlation between them were -0.985, -0.947 and -0.942, respectively.

This paper is concerned with the theoretical foundation of support vector machines (SVMs). The purpose is to develop further an exact relationship between SVMs and the statistical learning theory (SLT). As a representative, the standard C-support vector classification (C-SVC) is considered here. More precisely, we show that the decision function obtained by C-SVC is just one of the decision functions obtained by solving the optimization problem derived directly from the structural risk minimization principle. In addition, an interesting meaning of the parameter C in C-SVC is given by showing that C corresponds to the size of the decision function candidate set in the structural risk minimization principle.

In this paper, a new ergodic property analysis model of hydrological process is proposed based on fuzzy-rough c-means clustering (FRCM), autocorrelogram, and fuzzy least absolute regression (FLAR). A precipitation time series (1951―2004) from Shanghai Hydrology Station is then analyzed with the model. The results show that the precipitation time series of April, May, June, and September has er-godic property. We conclude that in the long run, the precipitation of April, May, June, and September will not keep decreasing; it will converge to its mean value in some period.

A quasi-secure quantum dialogue protocol using single photons was proposed. Different from the previous entanglement-based protocols, the present protocol uses batches of single photons which run back and forth between the two parties. A round run for each photon makes the two parties each obtain a classical bit of information. So the efficiency of information transmission can be increased. The present scheme is practical and well within the present-day technology.
