The security of natural gas supply and demand has always been an important topic, and as a result, analyzing and predicting the supply and demand of natural gas has received considerable attention from researchers. Numerous studies have extensively researched the supply and demand of natural gas. The main purpose of this study is to explore the supply‐demand balance mechanism for natural gas security. A system dynamics model is constructed to assess the supply and demand of natural gas in Sichuan Province, China. A new system dynamics model based on domestic gas, production gas, ecological environment and natural gas supply is proposed. The study considers four scenarios: natural development, economic priority development, environmental priority development and coordinated development. The results show that the rapid economic development has led to an excessive environmental carrying capacity, a larger gap between natural gas supply and demand, a decline in the quality of life of residents, and even affected the energy security of Sichuan Province and China. The findings also show that people's overprotection of the environment can lead to slow economic development, which prevents it from achieving its desired goals. The coordinated development scenario in this paper not only ensures the production of natural gas and the quality of life of residents, but also is an optimal scheme with low energy consumption and pollution. According to the research conclusions, considering the overall situation of China's energy security and the situation in Sichuan Province, the author proposes reforms from the supply and demand sides of natural gas.

On the basis of morphological examination, field investigation, observation of cultivated accessions and statistical analysis, the genus Miscanthus s.l. (Poaceae) from China was taxonomically revised. Two subgenera ( Miscanthus subgenus Miscanthus and Miscanthus subgenus Diandranthus), two sections [ Miscanthus subgenus Miscanthus section Miscanthus and Miscanthus subgenus Miscanthus section Triarrhena (Maximowicz) Honda], six species, two subspecies and four varieties in this genus were recognized in this report. Miscanthus sacchariflorus ssp. lutarioriparius and Miscanthus nudipes var. yunnanensis were also recognized. A key to the taxa of Miscanthus from China is provided. A morphological description, distribution, and habit and phenology are summarized for each species. Distribution maps and morphological illustrations of each species are also provided. © 2010 The Linnean Society of London, Botanical Journal of the Linnean Society, 2010, 164, 178-220.

Multi-temporal Interferometric Synthetic Aperture Radar (MT-InSAR) technique has proven to be a powerful tool for the monitoring of time-series ground deformations along the line-of-sight (LOS) direction. However, the one-dimensional (1-D) measurements cannot provide comprehensive information for interpreting the related geo-hazards. Recently, a novel method has been proposed to map the three-dimensional (3-D) deformation associated with underground fluid flows based on single-track InSAR LOS measurements and the deformation modeling associated with the Green's function. In this study, the method is extended in temporal domain by exploiting the MT-InSAR measurements, and applied for the first time to investigate the 3-D time series deformation over Sebei gas field in Qinghai, Northwest China with 37 Sentinel-1 images acquired during October 2014-July 2017. The estimated 3-D time series deformations provide a more complete view of ongoing deformation processes as compared to the 1-D time series deformations or the 3-D deformation velocities, which is of great importance for assessing the possible geohazards. In addition, the extended method allows for the retrieval of time series of fluid volume changes due to the gas extraction in the Sebei field, which agrees well with those from the PetroChina Qinghai Oilfield Company Yearbooks (PQOCYs). This provides a new way to study the variations of subsurface fluids at unprecedented resolution. [ABSTRACT FROM AUTHOR]

The article reports that acute myeloid leukaemia is a heterogeneous disease that has been explored in depth using cytogenetic and molecular techniques. Topics include examines allogeneic haematopoietic stem cell transplantation is a curative therapy for AML and considered relapse remains an important problem as extensive evidence has shown that Wilms' tumor gene 1 expression is a useful biomarker for measurable/minimal residual disease monitoring in AML.
