Perceiving China's Energy Development from the World Key Energy Statistics

As the world's authoritative organization on energy information, the International Energy Agency (IEA), which was founded in 1974, releases Key World Energy Statistics every year from 1997 (hereinafter referred to as the "Key Data"). The "Key Data" released in 2007 announced the 2005 statistics, and also provided the 1973 statistics for comparison. From the published data, we can clearly find the development path and trend of the world energy and power industry. Also, China's strong development momentum, high- speed growth of energy consumption and the enormous challenges in the sustainable energy supply are especially noticeable. This paper reviewed the "Key Data" to perceive China's Energy Development. The analysis and interpretation of these data are purely from the author's point of view.

Forkhead box protein P1, a key player in neuronal development?

Forkhead box protein P1（FOXP1）is a transcription factor belonging to the forkhead box（FOX）proteins,a family of transcriptional regulators sharing a highly conserved forkhead DNA-binding domain（Bacon and Rappold,2012）.Previous reports have proposed a role for FOXP1 in functionally regulating the central nervous system（CNS）,while mutations in FOXP1 have been implicated in cognitive abnormalities（Bacon and Rappold, 2012）.

Development Trends of Key Technologies for IPTV Systems

Fast growing IPTV services have become a major concern in China’s information industry. However,the IPTV service model has not been perfected yet after long-time trial made in a couple of Chinese cities. Selecting optimum technologies for IPTV is difficult to solve in the short term. So far most trial IPTV services in China are designed to provide a small number of local viewers with television and recorded programs. Accordingly,the technology used for the available IPTV services can hardly become a paradigm for future IPTV technology development. Therefore,with the ultimate goal of constructing a countrywide IPTV service network that can meet the requirements of commercial operation,it is necessary to conduct research into the design of countrywide IPTV network architecture,improvement of the bearer network,selection of video encoding technology,terminal structure,building of the Content Distribution Network (CDN),establishment of the open Digital Rights Management (DRM) platform,and construction of Media Asset Management (MAM) system.

Gene regulatory network inference based on causal discovery integrating with graph neural network

Gene regulatory network (GRN) inference from gene expression data is asignificant approach to understanding aspects of the biological system.Compared with generalized correlation-based methods, causality-inspiredones seem more rational to infer regulatory relationships. We proposeGRINCD, a novel GRN inference framework empowered by graph representationlearning and causal asymmetric learning, considering both linearand non-linear regulatory relationships. First, high-quality representation ofeach gene is generated using graph neural network. Then, we apply theadditive noise model to predict the causal regulation of each regulator-targetpair. Additionally, we design two channels and finally assemble them forrobust prediction. Through comprehensive comparisons of our frameworkwith state-of-the-art methods based on different principles on numerousdatasets of diverse types and scales, the experimental results show that ourframework achieves superior or comparable performance under variousevaluation metrics. Our work provides a new clue for constructing GRNs,and our proposed framework GRINCD also shows potential in identifyingkey factors affecting cancerdevelopment.

Phosphatidic acid plays key roles regulating plant development and stress responses

Phospholipids, including phosphatidic acid （PA）, phosphatidylcholine （PC）, phosphatidylethanolamine （PE）, phosphatidylglycerol （PC）, phosphatidylserine （PS） and phosphoinositides, have emerged as an important class of cellular messenger molecules in various cellular and physiological processes, of which PA attracts much attention of researchers. In addition to its effect on stimulating vesicle trafficking, many studies have demonstrated that PA plays a crucial role in various signaling pathways by binding target proteins and regulating their activity and subcellular localization. Here, we summarize the functional mechanisms and target proteins underlying PA-mediated regulation of cellular signaling, development, hormonal responses, and stress responses in plants.

Receptor-like protein kinases:Key regulators controlling root hair development in Arabidopsis thaliana

Root hairs are tubular outgrowths specifically differentiated from epidermal cells in a differentiation zone. The formation of root hairs greatly increases the surface area of a root and maximizes its ability to absorb water and inorganic nutrients essential for plant growth and development. Root hair development is strictly regulated by intracellular and intercellular signal communications. Cell surface-localized receptor-like protein kinases （P, LKs） have been shown to be important components in these cellular processes, tn this review, the functions of a number of key P, LKs in regulating Arabidopsis root hair development are discussed, especially those involved in root epidermal cell fate determination and root hair tip growth.
