Imprinting in plants

Chinese Science Bulletin 2009年第14期54卷 2383-2389页

作者： GUTIERREZ-MARCOS jose Warwick HRI University of WarwickWellesbourneCV35 9EF UK

Genomic imprinting leads to the differential expression of parental alleles after fertilization. Imprinting appears to have evolved independently in mammals and flowering plants to regulate the development of nutrient-transfer placental tissues. In addition, the regulation of imprinting in both mammals and flowering plants involves changes in dNA methylation and histone methylation, thus suggesting that the epigenetic signals that regulate imprinting have been co-opted in these distantly related species.

1 Introduction The fact that most of the world’s population lives in cities(UN-Habitat 2016)has increased interest in urban *** models,such as the Weather Research and Forecasting(WRF)model(***/weather-research-and-forecasting-model),are used to reproduce the meteorology and climatology over cities and around them,where the complex interactions between the atmosphere and urban surfaces(buildings,vegetation,urban obstacles,etc.)induce strong heterogeneity in the flow properties within the urban canopy layer(UCL)(di Sabatino et al.2013;Lateb et al.2016;Tominaga and Stathopoulos 2016).

A multilayer perceptron(MLP) artificial neural network(ANN) model has been optimized by the multi-objective ant colony optimization(MOACO) algorithm, which uses three objective functions. A sensitivity analysis to choose MOACO parameter values is carried out by calculating hypervolume metric, and the proposed approach adopts the Vlsekriterijumska Optimizacija I Kompromisno Resenje(VIKOR) decision method to choose final compromised solution on the Pareto front obtained from MOACO. As a result, we used the MLP-MOACO developed model to estimate the value of engine emissions of NOxin a four stroke, spark ignition(SI) gasoline engine and observed acceptable correlation coefficient(R^2) of 0.99978.

The constant need for high-strength materials in the construction industry promotes the research of additives that improve the properties of masonry materials. The use of allophane as an additive in concrete and mortar mixtures was implemented to improve their strength and waterproofing, respectively, using compression and water absorption tests according to their corresponding standards (ASTM C1231, ASTM d2938, and ASTM C1585). The samples were evaluated at different concentrations and curing ages. In addition, different sand/cement ratios were considered for the mortar. The results revealed that there was a 9.4% increase in compressive strength in concrete and a 23.7% reduction in water absorption in mortar for the 5:1 ratio. These changes would be the result of the interaction of the nanoporous additive in the atomic crystal structure of the material demonstrating the nanotechnological nature of allophane.

THE SWI/SNF COMPLEXESIn plants, as well as in metazoans, the execution of devel- opmental programs and the response to environmental stimuli depend on changes in gene transcription programs that require extensive chromatin modifications of basically two types： posttranslational modification of histones and ATP-dependent reorganization of histones-dNA interac- tions. Many different nuclear machineries are necessary to carry out chromatin modifications at the appropriate time and place.

Underground salt cavern CO2storage（SCCS） offers the dual benefits of enabling extensive CO2storage and facilitating the utilization of CO2resources while contributing the regulation of the carbon *** economic and operational advantages over traditional carbon capture, utilization, and storage（CCUS） projects make SCCS a more cost-effective and flexible option. despite the widespread use of salt caverns for storing various substances, differences exist between SCCS and traditional salt cavern energy storage in terms of gas-tightness, carbon injection, brine extraction control, long-term carbon storage stability, and site selection criteria. These distinctions stem from the unique phase change characteristics of CO2and the application scenarios of SCCS. Therefore, targeted and forward-looking scientific research on SCCS is imperative. This paper introduces the implementation principles and application scenarios of SCCS, emphasizing its connections with carbon emissions, carbon utilization, and renewable energy peak shaving. It delves into the operational characteristics and economic advantages of SCCS compared with other CCUS methods, and addresses associated scientific challenges. In this paper, we establish a pressure equation for carbon injection and brine extraction, that considers the phase change characteristics of CO2,and we analyze the pressure during carbon injection. By comparing the viscosities of CO2and other gases,SCCS's excellent sealing performance is demonstrated. Building on this, we develop a long-term stability evaluation model and associated indices, which analyze the impact of the injection speed and minimum operating pressure on stability. Field countermeasures to ensure stability are proposed. Site selection criteria for SCCS are established, preliminary salt mine sites suitable for SCCS are identified in China, and an initial estimate of achievable carbon storage scale in China is made at over 51.8–77.7 million tons, utilizing only 20%–30

In this paper we modify the EBdF method using the NdFs as predictors instead of BdFs. This modification, that we call ENdF, implies the local truncation error being smaller than in the EBdF method without losing too much stability. We will also introduce two more changes, called ENBdF and EBNdF methods. In the first one, the NdF method is used as the first predictor and the BdF as the second predictor. In the EBNdF, the BdF is the first predictor and the NdF is the second one. In both modifications the local truncation error is smaller than in the EBdF. Moreover, the EBNdF method has a larger stability region than the EBdF.
