Abstract

Based on the nickel-base alloy production platform of Fushun Special Steel Co.， LTD.， this paper studies the feasibility of "30 t non-vacuum induction furnace-external furnace refining-electroslag remelting" process instead of the traditional high cost process to smelt nickel-base alloys with high molybdenum content， and analyzes the production efficiency and cost advantages combined with the production practice. The results show that by degassassing smelting process scheme with 30 t non-vacuum induction furnace was used to melt molten steel ， VOD blowing oxygen and decarbonized after vacuum to below 67 Pa， and the smelting of nickel-base alloy N06625 and N10276 products with high molybdenum content was successfully realized.The steel ingot produced after electroslag is 204 mm forging products， the chemical composition and non-metallic inclusions meet the industry standard requirements， and further improve the production guarantee and cost control ability of high molybdenum nickel-base alloy.

Abstract

Salted duck egg yolk, a key ingredient in various specialty foods in China, frequently contains broken eggshell fragments embedded in the yolk due to high-speed shell-breaking processes, which pose significant food safety risks. This paper presents an online detection method, YOLOv7-SEY-DeepSORT (salted egg yolk, SEY), designed to integrate an enhanced YOLOv7 with DeepSORT for real-time and accurate identification of salted egg yolks with impurities on production lines. The proposed method utilizes YOLOv7 as the core network, incorporating multiple Coordinate Attention (CA) modules in its Neck section to enhance the extraction of subtle eggshell impurities. To address the impact of imbalanced sample proportions on detection accuracy, the Focal-EIoU loss function is employed, adaptively adjusting bounding box loss values to ensure precise localization of yolks with impurities in images. The backbone network is replaced with the lightweight MobileOne neural network to reduce model parameters and improve real-time detection performance. DeepSORT is used for matching and tracking yolk targets across frames, accommodating rotational variations. Experimental results demonstrate that YOLOv7-SEY-DeepSORT achieves a mean average precision (mAP) of 0.931, reflecting a 0.53% improvement over the original YOLOv7. The method also shows enhanced tracking performance, with Multiple Object Tracking Accuracy (MOTA) and Multiple Object Tracking Precision (MOTP) scores of 87.9% and 73.8%, respectively, representing increases of 17.0% and 9.8% over SORT and 2.9% and 4.7% over Tracktor. Overall, the proposed method balances high detection accuracy with real-time performance, surpassing other mainstream object detection methods in comprehensive performance. Thus, it provides a robust solution for the rapid and accurate detection of defective salted egg yolks and offers a technical foundation and reference for future research on the automated and safe processing of egg products.

Abstract

The plant hormone abscisic acid (ABA) is able to regulate the expression of ABA-responsive genes via signaling transduction, and thus plays an important role in regulating plant responses to abiotic stresses. Hence, characterization of unknown ABA response genes may enable us to identify novel regulators of ABA and abiotic stress responses. By using RT-PCR analysis, we found that the expression levels of ABA-induced Serine-rich Repressor 1 (ASR1)and ASR2, two closely related unknown function genes, were increased in response to ABA treatment. Amino acid sequence analyses show that ASR1 contains an L×L×L motif and both ASR1 and ASR2 are enriched in serine. Transfection assays in Arabidopsis leaf protoplasts show that ASR1 and ASR2 were predominantly localized in the nucleus and were able to repress the expression of the reporter gene. The roles of ASRs in regulating ABA responses were examined by generating transgenic Arabidopsis plants over-expressing ASR1 and ASR2, respectively, and CRISPR/Cas9 gene-edited single and double mutants for ASR1 and ASR2. In both the seed germination and cotyledon greening assays, ABA sensitivity remained largely unchanged in the over-expression transgenic plants and the single mutants of ASR1 and ASR2, but greatly increased ABA sensitivity was observed in the asr1 asr2 double mutants. In root elongation assays, however, decreased ABA sensitivity was observed in the 35S:ASR1 and 35S:ASR2 transgenic plants, whereas increased ABA sensitivity was observed in the asr1 and asr2 single mutants, and ABA sensitivity was further increased in the asr1 asr2 double mutants. Transcriptome analysis show that the differentially expressed genes (DEGs) down-regulated in the 35S:ASR1 transgenic plant seedlings, but up-regulated in the asr1 asr2 double mutant seedlings were highly enriched in processes including responses to plant hormones and stress stimuli. Taken together, our results show that ASR1 and ASR2 are closely related ABA response genes, ASR1 and ASR2 are serine-rich novel transcription repressors, and they negatively regulate ABA responses in Arabidopsis in a redundant manner.
