Multi-object tracking is a fundamental problem in computer vision， and DeepOCSORT， due to its reliance on the 2D image position information of targets， tends to exhibit prediction drift. To enhance the tracking stability of DeepOCSORT， this paper proposes a novel multi-sensor data fusion-based multi-object tracking method. Specifically， we build upon the DeepOCSORT foundation and additionally integrate target velocity information directly measured by LiDAR. The introduction of this velocity information is conducted from three perspectives: firstly， during data association， a penalty term is constructed based on the differences in target velocities to constrain generating matches with consistent velocities; secondly， using LiDAR velocity for initialization and online updating of the velocity state within the tracker， making tracking predictions more stable; thirdly， controlling the degree of dependence on velocity information by adjusting the process noise covariance matrix. Evaluation results on the KITTI dataset demonstrate that compared to the original DeepOCSORT， the proposed improved multi-source heterogeneous information fusion method significantly enhances tracking performance， with maximum improvements of 3.35， 3.26， and 3.71 on the HOTA， MOTA， and IDF1 metrics， respectively. This study provides an effective approach to building a more stable and accurate multi-object tracking system.

Sexual maturation heterosis has been widely exploited in animal crossbreeding. However, the underlying mechanism has been rarely explored in chicken. In the present study, we performed the reciprocal crossing between White Leghorn and Beijing You chicken to evaluate the phenotypes related to sexual maturation,and profiled the ovary circRNAs of purebreds(WW, YY) and crossbreds(WY, YW) to elucidate the molecular mechanism underlying heterosis for sexual maturation. Pubic space and oviduct length exhibited positive heterosis,and age at first egg(AFE) exhibited negative heterosis in the crossbreds. We identified 3,025 known circRNAs and 624 putative circRNAs, which were mainly derived from the exons. Among these circRNAs, 141 and 178circRNAs were specially expressed in WY and YW, respectively. There were 52.38 and 64.63% of total circRNAs in WY and YW exhibited non-additive expression pattern, respectively. GO enrichment and KEGG pathway analysis showed that the host genes of non-additive circRNAs were mainly involved in TGF-beta signaling pathway, oocyte development, ATPase activator activity, oocyte meiosis, progesterone-mediated oocyte maturation and GnRH signaling pathway. Weighted gene co-expression network analysis identified that 4 modules were significantly(P<0.05) correlated with oviduct length and pubic space. The host genes of non-additive circRNAs harbored in the 4 modules were associated with MAPK signaling pathway and Wnt signaling pathway. Furthermore, competing endogenous RNAs(ceRNA) network analysis characterized non-additive circRNAs gal-FGFR2＿0005 and galMAPKAP1＿0004 could interact with gga-miR-1612 and gga-miR-12235-5p to regulate CNOT6, COL8A1, and FHL2,which were essential for ovary development, indicating that the non-additive circRNAs involved in the formation of sexual maturation heterosis through regulating genes related to the reproductive and developmental process. The findings would provide a deeper understanding of the molecular mechanism u

加快数字关键核心技术突破式创新是形成数字经济国际竞争力以及迈向高水平科技自立自强的必由之路。然而,集群视角下数字关键核心技术突破式创新的机理尚不清晰。本文立足数字产业集群视角,探究数字关键核心技术突破式创新的作用机制,将数字产业集群试点政策视为准自然实验,探析其对数字关键核心技术领域突破式创新的作用机制与路径。研究结果表明,数字产业集群政策促进了数字关键核心技术突破式创新,这一作用有赖于集群内主体间协同专业化创新、数字技术扩散以及数字创新要素配置效率提升机制。在路径分析方面,数字产业集群政策通过协同专业化创新路径发挥作用的效应约为43.54%,数字技术扩散路径效应约为26.18%,数字创新要素配置效率提升路径效应约为16.60%。异质性分析发现,对于经济活跃度与数字经济发展活跃度较高的地区以及数字基础设施相对完善的地区而言,数字产业集群政策的作用效果更好。进一步地,供应链关联与集群政策之间发挥互补性作用,二者形成相互渗透的合力促进数字关键核心技术突破式创新;创新链关联与集群政策之间体现为替代作用,对于创新链关联强度较弱的地区,政策作用效果更明显。

OBJECTIVE: To explore if Hewei Jiangni granule（和胃降逆颗粒, HWJNG） could regulate esophageal hypersensitivity via stromal interaction molecule 1（STIM1）/transient receptor potential vanilloid subfamily member 1（TRPV1） pathway. METHODS: Qualitative analysis of HWJNG was analysis by high performance of liquid and gas chromatography. In vivo, animal model of non-erosive reflux disease（NERD） was established by fructose intake and restraint stress. HWJNG and Omeprazole were administered by gavage to the drug intervention group. Reflux and visceral hypersensitivity were analyzed by pathological changes, PH value test, mechanical paw withdrawal threshold, thermal withdrawal latency and mast cells（MCs） degranulation. In vitro, substance P（SP）-induced P815 cells and dorsal root ganglion（DRG） cells were cocultured. Expression in both mice and cells of STIM1, TRPV1, and esophageal visceral hypersensitivity-related gastrointestinal neurochemicals were validated by enzyme linked immunosorbent assays, quantitative realtime polymerase chain reaction（qRT-PCR） and Western blot. Moreover, overexpression and small interfering RNA against STIM1 were utilized to verify of the role of HWJNG in DRG cells. RESULTS: HWJNG significantly suppressed intercellular space widening, injury of mitochondrial, MCs degranulation, mechanical allodynia and heat neuropathic sensory and increased pH value of esophageal mucosa in NERD mice. HWJNG inhibited expression of visceral hypersensitivityrelated gastrointestinal neurochemicals in esophageal mucosa and activated P815 cells, and expression of the STIM1, TRPV1 and related neurotransmitters in DRG and DRG cells. STIM1 siRNA and HWJNG both reduced P815 cells adhesion to DRGs cells and Ca2+flow into the cytoplasmic space of DRG cells. Furthermore, HWJNG could reversed STIM1 overexpression induced upregulation of TRPV1. CONCLUSION: HWJNG suppressed intercellular space widening in NERD mice, stabilized MCs and restored neuronal hyperexcitability by regulating vis
