On coordinated development of oasis and environment in arid area

FU Xiao-feng,LI Zhe,

地理学报 , 2001,
Abstract: Based upon the formation and evolution of oasis and the factors restricting the coordinated development of oasis economy and environment, this paper presents a goal of the development in coordination. It suggests that the sustainable survival and development of oasis could be ensured only if the oasis-desert and water source ecology are managed in a combined way to form a macro system. In light with the above mentioned, the approach to the development of economy and environment of oasis in arid area should depend upon the establishment of an oasis ecological and economic system, which suits the arid environment and promotes the efficiency of resource configuration, stabilizes economic increment and benefits ecological development.

Xiao Xue,Zhe Wei,Zhifeng Zeng
Journal of Software , 2012, DOI: 10.4304/jsw.7.4.733-740
Abstract: In order to help small and medium enterprises (SMEs) cluster to face the global challenges, the definition of “cluster supply chain” is put forward as a new type of management pattern, which is the combination of industrial cluster and supply chain management. However, the related research on cluster supply chain is still in its infancy, and it is difficult to put theory results into practice. Based on the background, we give a case study of collaborative procurement in a textile & garment industry cluster to demonstrate the construction and development of cluster supply chain, in which the role of service system is described in detail. In the end, this paper summarizes an analytic framework to present the completed modeling process of collaborative procurement. The framework includes four views - business modeling, specification modeling, realization modeling, system evolution.

Journal of Software , 2011, DOI: 10.4304/jsw.6.11.2146-2153
Abstract: In order to help small and medium enterprises (SMEs) cluster to face the global challenges, the definition of “cluster supply chain” is put forward as a new type of management pattern, which is the combination of industrial cluster and supply chain management. However, the related research on cluster supply chain is still in its infancy, and it is difficult to put theory results into practice. Based on the background, this paper presents an analytic framework to bridge the gap between theory and practice in the field. The framework includes four views - business modeling, specification modeling, realization modeling, system evolution, and integrates methods from value network modeling, agent oriented modeling and service oriented analysis &design. In the end, we utilize a case study of China textile industry for demonstrating how to apply the framework to provide new insights into the construction and development of cluster supply chain.
Bis(μ-2′-carboxylatobiphenyl-2-carboxylic acid-κ2O2:O2′)bis[(2,2′-bipyridine-κ2N,N′)(2′-carboxylatobiphenyl-2-carboxylic acid-κO2′)zinc(II)]

Abstract: In the dimeric title compound, [Zn2(C14H9O4)4(C10H8N2)2], the ZnII ions are pentacoordinated by one 2,2′-bipyridyl ligand and by three O atoms from three 2′-carboxylatobiphenyl-2-carboxylic acid ligands. Two of the 2′-carboxylatobiphenyl-2-carboxylic acid ligands act as bridging ligands and, together with two zinc(II) cations, produce an 18-membered ring system. The remaining 2′-carboxylatobiphenyl-2-carboxylic acid ligands work as monodentate ligands. The crystal packing diagram is consolidated by O—H...O hydrogen bonds.

Abstract: Under the assumption that the earth movement tendency is a sphere, the author does research about the earthquakes occurrence between 2001 and 2010 which over 6 scales of magnitude on occurred time (UTC), magnitude, longitude, latitude and other data, then give out the causal relationship of earthquakes and the co-planarity and symmetry theory of earthquake occurrence. Also, the author does empirical analysis in the paper.
The Law of Genetic Inheritance  [PDF]
Yin Zhe
Open Journal of Genetics (OJGen) , 2012, DOI: 10.4236/ojgen.2012.21005
Abstract: In this paper, based on binomial formula, a law of genetic inheritance is proposed, and it would have certain reference value for future genetic inheritance research. Besides, a recursive algorithm for recessive inheritance is also proposed. Given any two of the male parent, female parent and filial generation, the genomic information of the third one can be calculated uniquely.
PD Power-Level Control Design for MHTGRs  [PDF]
Zhe Dong
Journal of Power and Energy Engineering (JPEE) , 2014, DOI: 10.4236/jpee.2014.24019
Abstract: Due to its inherent safety feature, the modular high temperature gas-cooled reactor (MHTGR) has been seen as one of the best candidates in building next generation nuclear plants (NGNPs). Since the MHTGR dynamics has high nonlinearity, it is necessary to develop nonlinear power-level controller which is not only beneficial to the safe, stable, efficient and autonomous operation of the MHTGR but also easy to be implemented practically. In this paper, based on the concept of shiftedectropy
and the physically-based control design approach, it is proved theoretically that the simple proportional-differential (PD) output-feedback power-level control can provide globally asymptotic closed-loop stability. Numerical simulation results verify the theoretical results and show the influence of the controller parameters to the dynamic response.
Information Fusion-Based Storage and Retrieve Algorithms for WSNs in Disaster Scenarios
Zhe Xiao,Ming Huang,Jihong Shi,Wenwei Niu,Jingjing Yang
International Journal of Distributed Sensor Networks , 2012, DOI: 10.1155/2012/524543
Abstract: Sensor networks are especially useful in catastrophic or disaster scenarios such as abysmal sea, floods, fires, or earthquakes where human participation may be too dangerous. Storage technologies take a critical position for WSNs in such scenarios since the sensor nodes may themselves fail unpredictably, resulting in the loss of valuable data. This paper focuses on fountain code-based data storage and recovery solutions for WSNs in disaster scenarios. A review on current technologies is given on challenges posed by disaster environments. Two information fusion-based distributed storage (IFDS) algorithms are proposed in the “few global knowledge” and “zero-configuration” paradigm, respectively. Correspondingly, a high-efficient retrieve algorithm is designed for general storage algorithms using Robust Soliton distribution. We observe that the successful decoding probability can be provisioned by properly selecting parameters—the ratio of number of source node and total nodes, and the storage capacity M in each node.
Rare earth elements and carbon isotope geochemistry of the Doushantuo Formation in South China: Implication for middle Ediacaran shallow marine redox conditions
ChuanMing Zhou,ShaoYong Jiang,ShuHai Xiao,Zhe Chen,XunLai Yuan
Chinese Science Bulletin , 2012, DOI: 10.1007/s11434-012-5082-6
Abstract: The middle Ediacaran Shuram excursion, the largest negative δ 13Ccarb excursion in Earth history, has been interpreted as indirect evidence for episodic oxidation and remineralization of deep ocean DOC (dissolved organic carbon). It has been hypothesized that such oxidation event may have occurred when anoxic DOC-laden deep water was brought to shallow shelves during oceanic upwelling, which is expected to cause localized anoxia in shallow environments. To test this prediction, we systematically analyzed rare earth elements (REE) and δ 13Ccarb of the upper Doushantuo Formation carbonates in the Yangtze Gorges area of South China, which were deposited in an inner shelf environment and record a large negative δ 13Ccarb excursion correlated to the Shuram event. The REE data show a significant positive shift in Ce/Ce* values, synchronous with a pronounced negative δ 13Ccarb shift. This positive Ce/Ce* shift is interpreted to represent an oceanic anoxia event in shallow shelf environments, which may have been caused by the upwelling or impingement of oxygen-depleted and 12C-enriched deep water onto shelves. This anoxia event coincides with a sharp decline in the abundance and diversity of Ediacaran acanthomorphic acritarchs, raising the possibility that these two geobiological events may be causally related.
Sponge fossil assemblage from the Early Cambrian Hetang Formation in southern Anhui

Chinese Science Bulletin , 2004, DOI: 10.1007/BF03184133
Abstract: Abundant well-preserved large articulated sponge fossils and isolated spicules have been reported from the Early Cambrian Hetang Formation, southern Anhui Province. This unique epifaunal fossil assemblage dominated by articulated sponge fossils is called the Xidi Sponge Fauna. The sponge fauna lived in a quiet oxygenic environment below the storm wave base. Bloom of phytoplankton and rapid sedimentation rate resulted in the deposition of the black shales. Sufficient food supply, lack of other competitors, abundant ecological niches, and demand for oxygen during early Cambrian were in favor of the diversification and evolution of large sponges in the Early Cambrian.
