Abstract

Digital transformation (DT), government intervention (GI) and carbon emissions (CE) have always been the focus of academic attention, and arguments on the relationship amongst them exist. This study seeks to introduce the degree of political connection and government subsidies (GS) as GI into the relationship between DT and CE at the micro-level and aims to provide a new perspective for resolving previous arguments. By using a difference-in-differences model, the impact of DT on reducing CE is measured by taking a sample of 3925 observations from listed enterprises in China and dividing them according to the following degrees of political connection: none, moderate and high. Results show that DT is effective in reducing CE. Additionally, DT of enterprises with moderate political connections has had the greatest effect on reducing CE, followed by the effect of enterprises with high political connections. The effect of enterprises with no political connections is insignificant. If enterprises with a moderate or no political connections gains more GS, then the negative impact of DT on CE will be stronger. This study provides new evidence that DT reduces CE at the micro-level and presents a new perspective on reaching a consensus by introducing GS and the degrees of political connection.

80. A Systematic Trajectory Tracking Framework for Robot Manipulators: An Observer-Based Nonsmooth Control Approach

Author

Han, Linyan, Mao, Jianliang, Zhang, Chuanlin, Kay, Robert W., Richardson, Robert C., and Zhou, Chengxu

Abstract

The mechanical design of a robot often influences the choice of control strategy, especially for high-dimensional manipulator systems with multiple inputs and outputs. Striking a balance between hardware and software, it remains a significant challenge to design a control framework that is both easy to implement and high performing. This article addresses this concern by developing a systematic control architecture for trajectory tracking problems, focusing solely on position measurements. The approach involves constructing a dynamic model of the manipulator in the joint space through parameter identification techniques. A nonsmooth observer is then devised to estimate unmeasured states, unknown disturbances, and uncertain nonlinear functions in real time, which are incorporated into a nonsmooth feedback control design to provide a control solution. The stability of the system is ensured using the homogeneous system theory and Lyapunov theorems. To validate the effectiveness and feasibility of the proposed tracking control approach, extensive evaluations are conducted on a six-degree-of-freedom manipulator, including tests for tracking performance and repeatability.

Abstract

We describe the new species Gomphonemopsis sieminskae from brackish waters of the East China Sea littoral near Ningbo, China. Two diatom strains isolated from Ulva sp. were successfully grown, then analyzed by light (LM) and scanning electron (SEM) microscopy. The new species is compared to known Gomphonemopsis species, and similarities to G. pseudoexigua and G. obscurum are emphasized. Although the size metric data overlap and the external views are fairly similar, the two taxa differ in their valve interior. Molecular barcoding strongly discriminated G. sieminskae from G. cf. exigua, while rbcL gene-based phylogeny showed G. sieminskae to be sister to Phaeodactylum tricornutum. In this respect our results confirm the recent discovery, based on molecular data, that Gomphonemopsis is a close-relative taxon to Phaeodactylum, and place it in Phaeodactylaceae instead of Rhoicospheniaceae as inferred solely from morphology.
