Article describes how forests are generally extracted from remotely sensed images based on the spectral features, ignoring other important auxiliary information, and the techniques of precise extraction need to be further improved. By using the Sentinel–2 image and auxiliary factors (AFs) including site conditions (SCs) and vegetation indices (VIs), the random forest model with AFs (RF–AFs) was adopted for the extraction of the economic forests in Lancang County, which is a mountainous area with rich biodiversity and is witnessing rapid development of economic forests in Yunnan province of China.

Article discusses how lipid droplets, also known as oil bodies or lipid bodies, are plant organelles that compartmentalize neutral lipids as a hydrophobic matrix covered by proteins embedded in a phospholipid monolayer. The authors review the growing body of knowledge about lipid droplets in plant cells, describe the evolutionary similarity and divergence in their associated subcellular machinery, and point to gaps that deserve future attention.
Article on lipid profiling revealing tissue-specific differences for N-acylethanolamines and their precursors in mice lacking fatty acid amide hydrolase.
Article states that mass-spectrometry-based screening of lipid extracts of wounded and unwounded leaves from a collection of 364 Arabidopsis thaliana T-DNA insertion lines produced lipid profiles that were scored on the number and significance of their differences from the leaf lipid profiles of wild-type plants. The analysis identified Salk_109175C, which displayed alterations in leaf chloroplast glycerolipid composition, including a decreased ratio between two monogalactosyldiacylglycerol (MGDG) molecular species, MGDG(18:3/16:3) and MGDG(18:3/18:3).

Study explores whether chronic inflammatory processes in systemic lupus erythematosus (SLE) are in part due to hypothalamic-pituitary-adrenal (HPA) axis dysfunction by challenging female control and SLE mice with lipopolysaccharide (LPS) and measuring c-Fos expression as an index of neuronal activation, plasma adrenocorticotrophic hormone (ACTH) as an index of anterior pituitary function, and plasma corticosterone as an index of adrenal function.
Article hypothesizing that lipoxygenase (LOX) participated in the metabolism of PU-NAEs through the formation of NAE-oxylipins. The data suggests that Arabidopsis LOXs indeed compete with FAAH to metabolize PU-NAEs during seedling establishment. Identification of endogenous amide-conjugated oxylipins suggests potential significance of these metabolites in vivo, and FAAH mutants may offer opportunities to address this in the future.
The cordial glass consists of two pieces which are similar in form. The ebony base holds the sterling silver vessel portion. At the top and bottom of the piece are similar thin silver bands.
These two cordial glasses are designed in the shape of an angular animal's horn or cornucopia, one piece in wood acts as the stand and the smaller one in metal acts as the drinking vessel portion.
This article describes a new methodology for monitoring sucrose labeling using liquid chromatography tandem mass spectrometry (LC-MS/MS). To date, the most commonly used method to monitor sucrose labeling is by nuclear magnetic resonance, which requires substantial amounts of biological sample.

Article describes how Li-CO2 batteries with a theoretical energy density of 1,876 Wh kg−1 are attractive as a promising energy storage strategy and as an effective way to reduce greenhouse gas emissions by CO2 reduction and the formation of discharge product Li2CO3 and carbon. This article provides critical perspectives on the development of Li-CO2 batteries as well as a description of current issues and challenges associated with cathode catalysts, electrolyte, and anode for Li-CO2 batteries.

The vertically oriented painting consists of many textures, colors and motifs. The dark ground is richly textured and covered with words, numbers and calculations sometimes partially obliterated. Two large heart shapes face each other, one in the bottom half of the canvas and the other in the top half. They are also richly covered in texture with letters and numbers. About a dozen forks are attached across the surface of the painting; they tumble from the top to the bottom. Flanking the top and bottom edges are some large X marks with thick top and bottom bars.
This article reports that local application of light stress to one rosette leaf of bolting Arabidopsis (Arabidopsis thaliana) plants resulted in a metabolic response that encompassed local, systemic and transport tissues, demonstrating a high degree of physical and metabolic continuity between different tissues throughout the plant.
This article argues that responsiveness, multi-level governance, and public entrepreneurship theories offer a fuller explanation for local government policy decision-making.

In this article, the author proves the existence of an infinite number of radial solutions of Δu+f(u)=0 on the exterior of the ball of radius R>0 centered at the origin and f is odd with f<0 on (0,β), f>0 on (β,δ), and f≡0 for u>δ. The primitive F(u)=∫u0f(t)dt has a "hilltop" at u=δ which allows one to use the shooting method and ODE techniques to prove the existence of solutions.

This review article summarizes the involvement and interaction between long-distance systemic acquired resistance (SAR) signals and details the recently discovered role of lysine catabolite pipecolic acid (Pip) in defense amplification and priming that allows plants to acquire immunity at the systemic level.
Article states that chiral materials, similarly to human hands, have distinguishable right-handed and left-handed enantiomers which may behave differently in response to external stimuli, so for the first time the authors use an approach based on the density functional theory (DFT)+PAOFLOW calculations to quantitatively estimate the so-called collinear Rashba–Edelstein effect (REE) that generates spin accumulation parallel to charge current and can manifest as chirality-dependent charge-to-spin conversion in chiral crystals. The authors reveal that the spin accumulation induced in the bulk by an electric current is intrinsically protected by the quasi-persistent spin helix arising from the crystal symmetries present in chiral systems with the Weyl spin–orbit coupling.
Article analyzing dispersion of sound in a solid-fluid layered structure and found a flex point on the isofrequency curve where D vanishes for given direction of propagation and frequency. Nonspreading propagation is experimentally observed in a water steel lattice of 75 periods (~1 meter long) and occurs in the regime of anomalous dispersion and strong acoustic anisotropy when the effective mass along periodicity is close to zero. Under these conditions the incoming beam experiences negative refraction of phase velocity leading to backward wave propagation. The observed effect is explained using a complete set of dynamical equations and our effective medium theory.
