[Spatiotemporal Characteristics and Configuration Paths of the Coupling Coordinated Development between Digital Economy and Green Logistics under the Background of "Dual Carbon"].

The coupling coordinated development between digital economy and green logistics is of great significance in promoting the integration of Digital China and Beautiful China and realizing the goal of "Double Carbon." For the purpose of clarifying the mechanism of coupling coordinated development between the digital economy and green logistics， this study applied the vertical and horizontal scatter degree method， modified coupling coordination degree model， cold-hot spot analysis， and dynamic aggregated fuzzy set qualitative comparative analysis （fsQCA） method to reveal the spatiotemporal characteristics and configuration paths of the coupling coordinated development between China's digital economy and green logistics during the period from 2013 to 2021. The findings showed that： ① In terms of temporal change， the development level of China's digital economy and green logistics fluctuated in an upward trend.

Research on transformer fault diagnosis method based on ACGAN and CGWO-LSSVM.

This paper proposes a transformer fault diagnosis method based on ACGAN and CGWO-LSSVM to address the problem of misjudgment and low diagnostic accuracy caused by the small number and uneven distribution of some fault samples in transformer fault diagnosis. Firstly, generate adversarial networks through auxiliary classification conditions, The ACGAN method expands a small and imbalanced number of samples to obtain balanced and expanded data; Secondly, the non coding ratio method is used to construct the characteristics of dissolved gases in oil, and kernel principal component analysis is used, KPCA method for feature fusion; Finally, using the improved cubic gray wolf optimization algorithm, CGWO for least square support vector machines, optimize the parameters of the LSSVM model and construct a transformer fault diagnosis model. The results show that the proposed method has a low false alarm rate and a diagnostic accuracy of 97.

The Discovery of Novel PGK1 Activators as Apoptotic Inhibiting and Neuroprotective Agents.

Stroke is the second leading cause of death worldwide and the leading cause of long-term disability that seriously endangers health and quality of human life. Tissue-type fibrinogen activator is currently the only drug approved by FDA for the treatment of ischemic stroke. Neuroprotection is theoretically a common strategy for the treatment of both ischemic and hemorrhagic stroke; therefore, the development of neuroprotective agent has been the focus of research.

[Chemical constituents from roots of Stelleropsis tianschanica].

The constituents from 95% ethanol extract of the roots of Stelleropsis tianschanica were purified by column chromatography techniques, leading to the isolation of 17 compounds. Their structures were elucidated by spectroscopic dataas 5'-methoxy lariciresinol(1), pinoresinol(2), daphnoretin(3), acutissimalignan B(4),(+)-secoisolariciresinol(5),(+)-epipinoresinol(6), 7-methyi-daphnoretin(7), thero-8S-7-methoxysyringylglycerol(8), 1-O-methyl-guaiacylglycerol(9), 2R-22'-ferulic acid ester-2,3-dihydroxypropyl ester(10), vesiculosin(11), 4β,5βH-guai-9,7(11)-dien-12,8-olide-1α,8α-diol(12),(-)-nortrachelogenin(13), 4α,5βH-guai-9,7(11)-dien-12,8-olide-1α,8α-diol(14), matairesinol(15), lariciresinol(16)and isolariciresinol(17). Among them, compounds 1-13 wereobtained for the first time fromthe genus Stelleropsis.

New Cassane Diterpenoids from Caesalpinia sappan and their Antiplasmodial Activity.

One new cassane diterpene possessing an unusual bridge between C-19 and C-20 named caesalsappanin R (), as well as another new diterpene caesalsappanin S (), were isolated from the seeds of with methanol extract. Their structures were determined by spectroscopic analysis and examined alongside existing data from prior studies. Their biological activities were profiled by their antiplasmodial activity.

[A new triterpenic acid from the roots of Rosa laevigata].

This study was designed to investigate triterpenoids from the roots of Rosa laevigata Michx. The silica gel column chromatography was used to separate the chemical constituents from the roots of Rosa laevigata Michx. HPLC was used to analyze its purity and chemical constitution.
