China is one of the countries which have the most earthquake disasters in the world. A total of 23 M ≥ 8 earthquakes occurred in Mainland China from 1303 to 2010. The seismic activity of M ≥ 8 earthquakes has had an obvious self-organized orderliness. The main ordered values are 252~258 a, 108~112 a, 94~98 a, 44~47 a, 24~25 a, 16~19 a, and 11~14 a. According to the information forecasting theory of Wen-Bo Weng and combining ordered analysis with complex network technology, we build an informational ordered network structure of M ≥ 8 great earthquakes in Mainland China and try to explore the practical method for M ≥ 8 great earthquake prediction with Chinese characteristics. In this paper, we have summarized the prediction research on two great earthquakes (the 2001 Kunlunshan M8.1 and the 2008 Wenchuan M8.0 earthquake) during the beginning of the 21st century in western Mainland China. At last, with the method of ordered network structure, we present a new prediction opinion: the future M ≥ 8 great earthquakes will happen in 2026 and 2065 pre and post in Mainland China. The results show that a M ≥ 8 great earthquake could be predicted and the network feature is the formation mechanism of great earthquakes. The ordered network method has a unique effect on moderate term and long term prediction for M ≥ 8 great earthquakes.

The northern Xizang Plateau is a main seismic zone inWest China. Since 1700, M ≥ 7 earthquakes have had an obvious commensurability and orderliness in this region. The main ordered values are 106∼107a, 77∼78a, 53∼54a, 26∼27a, 11∼12a, and 3∼4a. According to the information forecasting theory ofWen-BoWeng (W. B.Weng, Fundamentals of Forecasting Theory. Petroleum Industry Press, Beijing 1984 (in Chinese)), combining ordered analysis with complex network technology, we try to explore the practical method for M ≥ 7 earthquake prediction with Chinese characteristics, and build a informational ordered network structure of M ≥7 earthquakes in the northern Xizang Plateau. In this paper, we study the prediction of three great earthquakes (the 2001 Kunlunshan M8.1, the 2008Wenchuan M8.0, and the 2010 M7.1 Yushu earthquake) during the beginning of the 21st century based on the method of ordered network structure, and give many famous earthquake examples in China and abroad. Meanwhile, the cause of formation about the Wenchuan and Yushu earthquake has been discussed primarily. At last, we present some new prediction opinions: the future M ≥7 earthquakes will happen in 2014 - 2015, 2026 - 2027, and 2030 pre and post in this region. The results show that this method has a unique effect on moderate term and long term prediction for great earthquakes.

According to the statistical data, a total of 23 M ≥ 8 earthquakes occurred in Mainland China from 1303 to 2012. The seismic activity of M ≥ 8 earthquakes has showed an obvious self-organized orderliness. It should be remarked especially that there were three ordered pairs of M ≥8 earthquakes occurred in West China during 1902 - 2001, of which the time interval in each pair of two earthquakes was four years. This is a unique and rare earthquake example in earthquake history of China and the world. In the guidance of the information forecasting theory of Wen-Bo Weng, based on previous research results, combining ordered analysis with complex network technology, this paper focuses on the summary of the ordered network structure of M ≥ 8 earthquakes, supplements new information, constructs and further optimizes the 2D- and 3D-ordered network structure of M ≥ 8 earthquakes to make prediction research. At last, a new prediction opinion is presented that the future ordered pair of great earthquakes will probably occur around 2022 and 2026 in Mainland China.

M ≥ 7 strong earthquakes have had an obvious commensurability and orderliness in Xinjiang, China, and its neighbourhood region since 1800. The main orderly values are 30a×k (k = 1,2, 3), 11 ~ 12a, 41 ~ 43a, and 18 ~ 19a. According to the informative forecasting theory of Wen-BoWeng and complex networks technology, we try to explore the practical methods for strong earthquake prediction with Chinese characteristics, and conceive the informational orderly network structure of M ≥ 7 strong earthquakes. Based on this, Yutian M7.3 strong earthquake was successful predicted in 2008. Meanwhile, the next strong earthquake with magnitude 7 or so will happen around 2014 - 2015 in this region. The results shows that strong earthquakes could be predicted. This method has an unique effect for mid-and-long term prediction of strong earthquakes.

Great earthquakes and tsunami can have a tremendous societal impact. The Lisbon earthquake and tsunami of 1755 caused tens of thousands of deaths in Portugal, Spain and NW Morocco. Felt as far as Hamburg and the Azores islands, its magnitude is estimated to be 8.5–9. However, because of the complex tectonics in Southern Iberia, the fault that produced the earthquake has not yet been clearly identified. Recently acquired data from the Gulf of Cadiz area (tomography, seismic profiles, high-resolution bathymetry, sampled active mud volcanoes) provide strong evidence for an active east dipping subduction zone beneath Gibraltar. Eleven out of 12 of the strongest earthquakes (M>8.5) of the past 100 years occurred along subduction zone megathrusts (including the December 2004 and March 2005 Sumatra earthquakes). Thus, it appears likely that the 1755 earthquake and tsunami were generated in a similar fashion, along the shallow east-dipping subduction fault plane. This implies that the Cadiz subduction zone is locked (like the Cascadia and Nankai/Japan subduction zones), with great earthquakes occurring over long return periods. Indeed, the regional paleoseismic record (contained in deep-water turbidites and shallow lagoon deposits) suggests great earthquakes off South West Iberia every 1500–2000 years. Tsunami deposits indicate an earlier great earthquake struck SW Iberia around 200 BC, as noted by Roman records from Cadiz. A written record of even older events may also exist. According to Plato's dialogues The Critias and The Timaeus, Atlantis was destroyed by ‘strong earthquakes and floods … in a single day and night’ at a date given as 11,600 BP. A 1 m thick turbidite deposit, containing coarse grained sediments from underwater avalanches, has been dated at 12,000 BP and may correspond to the destructive earthquake and tsunami described by Plato. The effects on a paleo-island (Spartel) in the straits of Gibraltar would have been devastating, if inhabited, and may have formed the basis for the Atlantis legend.

Single-walled carbon nanotubes (SWNTs) are expected to be a promising nanomaterial because of their outstanding electronic, mechanical, and thermal properties. For macroscopic device applications, an assembly of SWNTs is a critical issue. We propose a self-organized micro-honeycomb network structure of SWNTs obtained by water vapor treatment of as-synthesized vertically-aligned SWNTs (VA-SWNT) for solar cell devices with higher performance. The micro-honeycomb structure was realized by simply exposing VA-SWNT to water vapor and drying in ambient condition. Honeycomb cell walls consist of capillary-aggregated vertically aligned SWNTs with heavily bundled top part. Within each cell, collapsed spaghetti-like SWNTs make contact to the substrate. The SWNT/n-Si heterojunction solar cell was built by placing the micro-honeycomb SWNTs network film on top of the substrate which has a 3 mm × 3 mm bare n-type silicon contact window in the center. The contact window is surrounded by SiO2 as insulating layer and Pt as electrode. Our preliminary tests showed that optimal photovoltaic conversion efficiency (PCE) under AM1.5 was 5.91%, with the fill factor of 72%. The open-circuit voltage and short-circuit current are 0.53V and 15.5 mA/cm2, respectively. This showed a substantial improvement compared with heterojunction solar cells using spaghetti-like SWNTs. Furthermore, the superior performance of dye-sensitized solar cells with the micro-honeycomb SWNTs was demonstrated.

AbstractM ≥7 earthquakes have showed an obvious commensurability and orderliness in Xinjiang of China and its adjacent region since 1800. The main orderly values are 30 a × k (k = 1,2,3), 11 ~ 12 a, 41 ~ 43 a, 18 ~ 19 a, and 5 ~ 6 a. In the guidance of the information forecasting theory of Wen-Bo Weng, based on previous research results, combining ordered network structure analysis with complex network technology, we focus on the prediction summary of M ≥ 7 earthquakes by using the ordered network structure, and add new information to further optimize network, hence construct the 2D- and 3D-ordered network structure of M ≥ 7 earthquakes. In this paper, the network structure revealed fully the regularity of seismic activity of M ≥ 7 earthquakes in the study region during the past 210 years. Based on this, the Karakorum M7.1 earthquake in 1996, the M7.9 earthquake on the frontier of Russia, Mongol, and China in 2003, and two Yutian M7.3 earthquakes in 2008 and 2014 were predicted successfully. At the same time, a new prediction opinion is presented that the future two M ≥ 7 earthquakes will probably occur around 2019 - 2020 and 2025 - 2026 in this region. The results show that large earthquake occurred in defined region can be predicted. The method of ordered network structure analysis produces satisfactory results for the mid-and-long term prediction of M ≥ 7 earthquakes.

This essay offers an analysis of the relationship of Sino-Christian theology, a cultural qua theological movement flourishing in contemporary China, with the Bible. Based on a survey of the articles published in Logos & Pneuma: Chinese Journal of Theology (Dao Feng), the organ journal of Sino-Christian theology, and some other relevant publications, it argues that due to the political atmosphere, the institutional restriction, and the intellectual as well as religious orientations of the relevant scholars, Sino-Christian theology had made very limited efforts in developing biblical studies as an academic discipline in mainland China until the mid-2000s or so. Since then, the publications related to biblical studies proliferated dramatically in mainland China, and some approaches to biblical studies with certain Chinese characteristics have been developed. It is expected that some innovative approaches to the Bible as well as biblical studies will be further developed in the Chinese-speaking world.
