摘要 ：
该文首先探讨了模型化的中微子在物质中振荡和混合的分析解,然后让中微子的CP违反相位旋转360°获得中微子振荡和混合的几何相位,发现几何相位随能量的振动具有非对称性几何结构.几何相位是描述中微子传播过程中内禀属性,故这种非对称结构起源于中微子振荡和混合的CP违反现象.因此,几何相位为中微子传播过程中的CP违反现象提供了线索.

摘要 ：
We present the exact analytic solution to the nonlinear dynamic system describing the information propagation process in complex networks. The method is to switch to the dynamic system of equations for the new variables defined according to the nonlinear terms appearing in the original dynamic system, and then, after combining relevant consistent condition of solution to reduce the dynamic system of equations for the newly defined variables to the knownly solvable nonlinear Bernoulli differential equation. Numerical comparisons between the purely numerical solution and the exact analytic solution confirm the crosscheck and mutual proof for both of the solutions. The presented exact analytic solution, which does not restrict the coefficients in the original dynamic system to merely constants, is thus suitable for the study of information propagation in networks with evolving structure and changing properties.

摘要 ：
This paper shows anthropic principle's predicting symmetric distribution matter strata, their physics laws, and verifications, concretely deduces characteristic time, energy, and temperature expressions at different scales, discovers four interesting invariant quantities, shows homeomorphic theorem of space map, and naturally presents a supersymmetric scale energy. We further discover that any infinitesimal space has the same proportional structure space; namely, they have renormalization group invariance. Consequently, this paper shows that the region of any nth level Plank-scope is from the nth level Planck scale to the (n+1)th level Planck scale, where the different matters of the nthlevel Planck scale build up the (n+1)th level Planck scale matter. The branches of physics science for this region include the nth level Planck scale matter dynamics and the nth level Planck scale matter group dynamics. The nth level Planck scale matter group dynamics describe how the nth level Planck scale matter constructs the (n+1)th level Planck scale matter and how the different matters of the nth level Planck scale evolve in the group system. This paper discovers that the different matters below Planck scale can exist with our matter world at the same time and same place and may be some candidates for dark matter; furthermore, this paper shows a relative theorem of matter scale: for the world of any nth level, the matters' sizes are relative, not absolute. Evidently, the discoveries of both the symmetrical distribution scales and the relations among the corresponding different physics laws from infinitesimal to infinitely large scales give a scientific solid development platform for formation of new scientific branches and deeper development of old scientific branches, because we can precisely construct many kinds of scientific theories relevant to all the corresponding matter strata. All the branch sciences of different matter strata up to now naturally need to be included in the framework of the new scientific system of physics.

摘要 ：
The curvaton scenario received much attention recently. It provides an alternative way to generate scale-invariant perturbations for the observed universe, besides the standard inflation paradigm. This paper studies the preheating in the nonminimal derivative coupling curvaton model with a nonstandard kinetic matter term, as a consequence of the large scale power spectrums of curvature perturbation. It is found that the nonstandard kinetic matter term is able to modify the behavior of the preheating, compared to the nonminimal derivative coupling curvaton model with standard kinetic matter term. Our result may provide an insight to the preheating process for bouncing cosmology or brane-inspired cosmology.

摘要 ：
For the (n-1)-domain wall universe induced by n-dimensional charged dilaton black hole, observers on the domain wall interpret its movement in the bulk as the expansion or collapsing of universe. By analyzing, we found that in this static AdS space, the cosmologic behavior of domain wall is particularly single. Even more surprising, there is an anomaly that the domain wall has a motion area outside the horizon, which cannot be explained by our classical theory.

摘要 ：
In this paper, we revisit the tunneling of charged particles from Kerr-Newman black holes by using Parikh and Wilczek's method, and obtain the general tunneling spectrum of emitted particles with arbitrary energy, charge and angular momentum. Based on the methods in Refs. [13-15], we find that, for the tunneling spectrum obtained, there exist correlations among sequential emissions, and the information that formerly was perceived to be lost is leaked out through such correlations. Thus, we resolve the black hole information loss paradox in a general case. (C) 2019 The Authors. Published by Elsevier B.V.

摘要 ：
In order to reduce the operation instability of rail transit station, optimize the structure of rail transit network and improve the efficiency of network operation, the stability of rail transit operation under the impact of large passenger flow was studied. Taking Beijing rail transit network as an example, Beijing rail transit network model with rail stations as nodes and adjacent stations as edges was constructed by using Space L method. The characteristic parameters and distribution rules of node degree, average path length, clustering coefficient, network diameter and network efficiency were simulated and analyzed. According to the type of accidents, these stations were divided into site operation weakened and operation disrupted, respectively. Base on passenger-flow propagation model and network efficiency model, the simulation quantified the network stability under the background of different event types. The results show that Beijing rail transit network is a scale-free network. The accessibility of rail transit network is better and clustering coefficient of it is small, but connectivity of it should be improved. And when site operation is weakened because of the large passenger flow in Beijing transit network, if the number of adjacent station is not more than 7, passenger-flow propagation state in network can regress, or negative correlation is observed between the number of adjacent station and the fading time. When transfer station is disrupted, the value of network efficiency will decrease significantly. The importance coefficient of the damaged site has the greatest impact on network efficiency in the range of (0.75, 1], and the least in the range of (0, 0. 5]. The research results provide a basis for timely finding the key points and weak links of rail network, ensuring the safety operation of urban rail transit network under the background of super passenger flow, and providing a decision support for the development of emergency plan of Beijing rail transit network under the impact of large passenger flow. 5 tabs, 5 figs, 16 refs. © 2018, Editorial Department of Journal of Chang'an University (Natural Science Edition).

摘要 ：
Based on the characteristics of rumor spreading in online social networks, this paper proposes a new rumor spreading model. This is a SIS rumor spreading model in online social networks that combines the transmission dynamics and population dynamics so that the impact of changing number of online social network users and user activity is considered. We numerically simulate the rumor spreading process. The results of numerical simulation show that the improved SIS model can successfully characterize the rumor spreading behavior in online social networks. We also give the effective strategies of curbing the rumor spreading in online social networks.

摘要 ：
Based on the characteristics of rumor spreading in online social networks, this paper proposes a new rumor spreading model. This is an improved SIS rumor spreading model in online social networks that combines the transmission dynamics and population dynamics with consideration of the impact of both of the changing number of online social network users and different levels of user activity. We numerically simulate the rumor spreading process. The results of numerical simulation show that the improved SIS model can successfully characterize the rumor spreading behavior in online social networks. We also give the effective strategies of curbing the rumor spreading in online social networks.
