The DBM strain utilized in this study was obtained from Yichun, Jiangxi Province, in 2019 and was reared for more than 30 generations at the Jiangxi Key Laboratory of Crop Growth Regulation, Yichun University. The DBMs were maintained at a relative humidity of 70% and a constant temperature of 27 ± 1 °C, following a light:dark cycle of 14 h to 10 h. Adult insects were provided with a 5% honey solution, while the larvae were fed with Chinese kale (Brassica oleracea var. alboglabra). The I.

AbstractIn aquaculture, real-time and rapid detection of dead fish is important for early risk warning and improving aquaculture efficiency. However, the complex actual environment and uncontrollable fish movement have brought great challenges to the detection of dead fish. Therefore, this paper proposes a high-precision and lightweight dead fish-detection transformer (DF-DETR) based on machine vision and original RT-DETR (real-time detection transformer).

AbstractIn recirculating aquaculture system, precise estimation of perch size from images is essential for developing intelligent management system. However, variations in fish postures and visual field lead to different fish sizes in RGB images, posing challenges for accurate fish detection and localization. To address the above issues, this paper proposes a nondestructive target detection and size measurement method for perch, based on depth information and RGB-D images.

To investigate the mechanism of seed vigor in hybrid and parents, artificial aging treatment was performed. Then we measured the germination index parameters of artificially accelerated aging treated seeds, including germination rate (GR), germination potential (GP), germination index (GI) and vigor index (VI). The results showed that the hybrid exhibited a higher GR than its parents (Fig.

AbstractThe occurrence of frugivorous bird species is strongly associated with the occurrence of fruit tree species in natural environments. However, the presence of a similar relationship in urban areas has not been explored. In this study, we used citizen science and field data to test for the existence of this relationship in 24 urban parks in Beijing, China.

In the presence of physical noise of all platforms for quantum computation, quantum error correction (QEC) becomes a critical way to realize quantum algorithms with large quantum volumes. In order to understand the influence of quantum noise on QEC codes and further improve the performance of logical circuits, the noises should be accurately analyzed with proper models. Here we focus on the trapped-ion system.

The ability to perform entangling operations in parallel with a low error is essential for a large-scale fault-tolerant quantum computer. However, for trapped-ion systems, it is a challenging task due to the crosstalk resulting from the collective motional modes. Here, we develop a highly paralleled quantum circuit demonstrating a logical qubit based on the Steane code and study the impact of the crosstalk error on the performance of the fault-tolerant protocol.
