Introduction: Forestry modernization (FM) and High quality economic development (HED) are two major goals that must be achieved in the process of economic development from low to high, and they are closely related to each other in their respective internal development mechanisms.

Methods: Based on the analysis of the coupling coordination mechanism between FM and HED, this paper empirically studies the coupling coordination degree and influencing factors of "forestry modernization and high quality economic development" ("FM-HED") using panel data from 30 provinces and cities in China (except Xizang, Hong Kong, Macao and Taiwan) from 2012 to 2020. First, the entropy method and the coupling coordination degree model were used to analyze the temporal changes and spatial differentiation of the coupling coordination between FM and HED.

Polymorphism of Niobium Phosphate Bronze NaNbPO Deduced by the Packings of Structural Units: A Centrosymmetric Phase.

Herein, a new centrosymmetric phase NaNbPO (referred to as CS-NaNbPO) was obtained by a molten salt method, which is a polymorph of niobium phosphate bronze NaNbPO. CS-NaNbPO displays high structural similarity to the noncentrosymmetric NaNbPO phase (referred to as NCS-NaNbPO): Distorted NbO octahedra are corner-coordinated to form ReO-type layers, which are further joined together by isolated PO tetrahedra. However, two polymorphous phases adopt different packings of structural units, resulting in distinct symmetries.

Melatonin alleviates endoplasmic reticulum stress to improve ovarian function by regulating the mTOR pathway in aged laying hens.

Granular cell apoptosis is a key factor leading to follicular atresia and decreased laying rate in aged laying hens. Endoplasmic reticulum stress (ERS) induced cell apoptosis is a new type of apoptosis pathway. Previous studies have shown that the ERS pathway is involved in the regulation of follicular development and atresia, and can be regulated by mTOR.

Nanozymes sensor array for discrimination and intelligent sensing of phenolic acids in food.

Although nanozymes sensor arrays have the potential to recognize multiple target substances simultaneously, they currently rarely identify phenolic acids in food due to limited catalytic performance and complex preparation conditions of nanozymes. Here, inspired by the structure of polyphenol oxidase, we have successfully prepared a novel gallic acid-Cu (GA-Cu) nanozyme with laccase-like activity. Due to the different catalytic efficiency of GA-Cu nanozymes towards six common phenolic acids, a three-channel colorimetric sensor array was constructed using reaction kinetics as the sensing unit to achieve high-throughput detection and identification of six phenolic acids within a concentration range from 1 to 100 μM.
