Abstract. Since 2000, CO2 emissions from emerging economies have outstripped those of developed economies. To limit global warming to under 1.5 ∘C by 2100, over 100 proposed net-zero carbon targets. Yet the supportive data are lacking – no inventory emission outlines detailed sources sector or distribution at subnational level for these Here, we redress balance establishing a dataset an energy-related that covers 47 sectors and eight energy types in 40...

Abstract Economic growth is principally powered by energy fuels. While the potential transition pathways in developed countries are clear, they have not been well explored for developing countries. Here, we study average annual rate of consumption 12 aggregated regions during 2001–2017 and driving factors behind that growth. The with high rates were concentrated Asia North Africa four top five Asia, while was stable or even declined period. Therefore, based on a comprehensive consideration...

Based on a monthly drought index, the Standardized Precipitation Index (SPI), we investigate multifractality of areas in seven major regions China from 1961 to 2012 using multifractal detrended fluctuation analysis. The results show that is evident time series for all regions, but its strength varies between areas. From numerical results, further examine stationarity and persistence characteristics variance big small fluctuations are also analyzed. spectra used distinguish features...

<title>Abstract</title> <bold>Background: </bold>Chemotherapy is regularly recommended for surgically rectal neuroendocrine carcinoma (NEC) patients. However, the additional benefit of perioperative radiotherapy these patients unclear to date. This study aims evaluate outcome in NECs who treated with surgery and chemotherapy. <bold>Methods: </bold>This a retrospective controlled based on SEER database. Propensity score matching (PSM) was applied reduce baseline bias. Rectal underwent...

Based on the NCEP/NCAR reanalysis data and Chinese observational during 1961–2013, atmospheric circulation patterns over East Asia in summer their connection with precipitation surface air temperature eastern China as well associated external forcing are investigated. Three of identified, all quasi-barotropic structures: (1) Asia/Pacific (EAP) pattern, (2) Baikal Lake/Okhotsk Sea (BLOS) (3) China/northern Okhotsk (ECNOS) pattern. The positive EAP pattern significantly increases Yangtze River...

Abstract. In this study, we propose an optimized long short-term memory (LSTM)-based approach which is applied to early warning and forecasting of ponding in the urban drainage system. This can quickly identify locate with relatively high accuracy. Based on approach, a model developed, constructed by two tandem processes utilizes multi-task learning mechanism. The superiority developed was demonstrated comparing widely used neural networks (LSTM convolutional networks). Then, further revised...

ABSTRACT Drainage modeling that accurately captures urban storm inundation serves as the foundation for flood warning and drainage scheduling. In this paper, we proposed a novel coupling ideology that, by integrating 2D-1D 1D-2D unidirectional processes, overcomes drawback of conventional approach fails to properly represent rainfall surface catchment dynamics, provides more coherent hydrological implications compared bidirectional concept. This paper first referred laboratory experimental...

The three summer drought patterns of the middle-lower reaches Yangtze River basin (MLRYRB) and their associated atmospheric circulation were investigated before after 1980. For whole-basin wide pattern during 1961–1979, anomalous high ridge over Japan blocked northerly flow from Siberia to southern China. Further, western Pacific subtropical (WPSH) was weaker than normal shifted eastward. northern flood zonal straight an anticyclonic located Japan. Less moisture transported China with...

By using the multi-fractal detrended fluctuation analysis method, we analyze nonlinear property of drought in southwestern China. The results indicate that occurrence China is and long-range correlated, these properties are indifferent to timescales. A power-law decay distribution well describes return interval events auto-correlation. Furthermore, a risk exponent based on correlation presented. This can give useful information about whether may or not occur future, provide guidance function...

Low air pressure is a feature of high-altitude regions. Domestic wastewater from such regions typically has low carbon-to-nitrogen ratio (C/N ratio). These factors combine to make traditional biological nitrogen removal in inefficient and more energy-intensive. The partial denitrification-anaerobic ammonium oxidation (PD/A) process was reported remove ammonia municipal sewage, consuming fewer carbon sources requiring no aeration supply. In this study, we set up laboratory-scale reactors...

<title>Abstract</title> Despite repeated calls to reduce CO2 emissions, asset managers continue invest heavily in carbon-intensive assets, creating hidden carbon bombs within their equity portfolios. Timely tracking of portfolio footprints is essential as a dynamic tool for monitoring companies' efforts reduction. However, the availability and quality firm-level emissions data present significant challenges measuring financed emissions. As result, potential climate-related risks are likely...

Abstract. An optimized LSTM-based approach applied to early warning and forecasting of ponding in the urban drainage system is proposed this study. This can identify locations process quickly with relatively high accuracy. The model constructed two tandem processes a multi-task learning mechanism introduced. results are compared those widely used neural networks (LSTM, CNN) validate its advantages. Then, revised available monitoring data study area achieve higher accuracy, influence number...

In autotrophic nitrogen removal, heterotrophic denitrifiers compete for nitrite/nitrate with in the presence of organic matter, leading to a decline denitrifiers. this study, combined process hydrolysis and chemically enhanced primary treatment (CEPT) was used sewage pretreatment that removed chemical oxygen demand (COD) but reserved total (TN). When raw water hydrolyzed 19 min, approximately 19% TN converted NH4+─N amino acid hydrolysate, resulting accounting about 75% water. FeCl3...

The Hengduan Mountains (HM) are located on the southeastern edge of Tibetan Plateau (TP) and feature high mountain ridges (&gt; 6000 m a.s.l.) separated by deep valleys. HM region also features an exceptionally biodiversity, believed to have emerged from topography interacting with climate. To investigate role regional climate, we conduct simulations climate model COSMO at horizontal resolutions (at ~12 km a convection-permitting scale ~4.4 km) for present-day We one control simulation...

Unified Job-Description Language on Chemical-Grid (UDLC) is a domain-specific language designed to write full-function chemical jobs quickly by providing common language. It frees chemists focus problem-solving rather than the details of various scripting languages (CSLs) and target runtime platform associated middleware. UDLC can directly invoke grid services without dealing with interaction grid, such as job submission, monitoring. Thus, it interesting meaningful for translate scripts in...
