TL;DR: The results suggest that the DDR complex acts in RdDM at a step upstream of the recruitment or activation of Pol V, suggesting that the mechanism(s) through which Pol V is targeted to specific genomic loci remains largely unknown.

TL;DR: A review of the main approaches to cross-covariance models can be found in this article, including the linear model of coregionalization, convolution methods, the multivariate Matern and nonstationary and space-time extensions of these among others.
Abstract: Continuously indexed datasets with multiple variables have become ubiquitous in the geophysical, ecological, environmental and climate sciences, and pose substantial analysis challenges to scientists and statisticians. For many years, scientists developed models that aimed at capturing the spatial behavior for an individual process; only within the last few decades has it become commonplace to model multiple processes jointly. The key difficulty is in specifying the cross-covariance function, that is, the function responsible for the relationship between distinct variables. Indeed, these cross-covariance functions must be chosen to be consistent with marginal covariance functions in such a way that the second-order structure always yields a nonnegative definite covariance matrix. We review the main approaches to building cross-covariance models, including the linear model of coregionalization, convolution methods, the multivariate Matern and nonstationary and space–time extensions of these among others. We additionally cover specialized constructions, including those designed for asymmetry, compact support and spherical domains, with a review of physics-constrained models. We illustrate select models on a bivariate regional climate model output example for temperature and pressure, along with a bivariate minimum and maximum temperature observational dataset; we compare models by likelihood value as well as via cross-validation co-kriging studies. The article closes with a discussion of unsolved problems.

01 Sep 2019TL;DR: In this paper, the authors discuss recent developments in anodes of SIB, including material synthesis, electrochemical performance, and sodium storage mechanisms, and analyze the critical issues, challenges, and future trends in SIB research, development, and commercialization.
Abstract: Lithium-ion batteries (LIBs) have been playing the leading role in energy storage modules of electric vehicles and hand-held electronics. The application of LIBs in future large-scale renewable energy storage may be hindered due to the cost and limited lithium resources in the earth crust. Sodium-ion battery (SIB) is considered to be an alternative for lithium-ion battery in large-scale renewable energy storage applications due to abundant sodium resources and similar electrochemical mechanisms. Compared with cathodes, the anodes of SIB show unstable performance and limited capacity, which has hindered the development and commercialization of SIBs. In this review, we discuss recent developments in anodes of SIB, including material synthesis, electrochemical performance, and sodium storage mechanisms. Additionally, we analyze the critical issues, challenges, and future trends in SIB research, development, and commercialization.

TL;DR: The models accurately predict growth phenotypes and known auxotrophies in CHO cells and show that the metabolic resources in CHO are more than three times more efficiently utilized for growth or recombinant protein synthesis following targeted efforts to engineer the CHO secretory pathway.
Abstract: Chinese hamster ovary (CHO) cells dominate biotherapeutic protein production and are widely used in mammalian cell line engineering research. To elucidate metabolic bottlenecks in protein production and to guide cell engineering and bioprocess optimization, we reconstructed the metabolic pathways in CHO and associated them with >1,700 genes in the Cricetulus griseus genome. The genome-scale metabolic model based on this reconstruction, iCHO1766, and cell-line-specific models for CHO-K1, CHO-S, and CHO-DG44 cells provide the biochemical basis of growth and recombinant protein production. The models accurately predict growth phenotypes and known auxotrophies in CHO cells. With the models, we quantify the protein synthesis capacity of CHO cells and demonstrate that common bioprocess treatments, such as histone deacetylase inhibitors, inefficiently increase product yield. However, our simulations show that the metabolic resources in CHO are more than three times more efficiently utilized for growth or recombinant protein synthesis following targeted efforts to engineer the CHO secretory pathway. This model will further accelerate CHO cell engineering and help optimize bioprocesses.

TL;DR: In this article, aqueous-processed CuSCN hole-transport layers (HTLs) are used to construct planar organometal halide perovskite solar cells.
Abstract: This study reports the development of copper(I) thiocyanate (CuSCN) hole-transport layers (HTLs) processed from aqueous ammonia as a novel alternative to conventional n-alkyl sulfide solvents. Wide bandgap (3.4–3.9 eV) and ultrathin (3–5 nm) layers of CuSCN are formed when the aqueous CuSCN–ammine complex solution is spin-cast in air and annealed at 100 °C. X-ray photoelectron spectroscopy confirms the high compositional purity of the formed CuSCN layers, while the high-resolution valence band spectra agree with first-principles calculations. Study of the hole-transport properties using field-effect transistor measurements reveals that the aqueous-processed CuSCN layers exhibit a fivefold higher hole mobility than films processed from diethyl sulfide solutions with the maximum values approaching 0.1 cm2 V−1 s−1. A further interesting characteristic is the low surface roughness of the resulting CuSCN layers, which in the case of solar cells helps to planarize the indium tin oxide anode. Organic bulk heterojunction and planar organometal halide perovskite solar cells based on aqueous-processed CuSCN HTLs yield power conversion efficiency of 10.7% and 17.5%, respectively. Importantly, aqueous-processed CuSCN-based cells consistently outperform devices based on poly(3,4-ethylenedioxythiophene) polystyrene sulfonate HTLs. This is the first report on CuSCN films and devices processed via an aqueous-based synthetic route that is compatible with high-throughput manufacturing and paves the way for further developments.
