This paper presents the details of our system designed for the Task 1 of Multimodal Information Based Speech Processing (MISP) Challenge 2021. The purpose of Task 1 is to leverage both audio and video information to improve the environmental robustness of far-field wake word spotting. In the proposed system, firstly, we take advantage of speech enhancement algorithms such as beamforming and weighted prediction error (WPE) to address the multi-microphone conversational audio. Secondly, several

For the video information, the provided region of interest (ROI) is used to obtain visual representation. Then the multi-layer CNN is proposed to learn audio and visual representations, and these representations are fed into our two-branch attention-based network which can be employed for fusion, such as transformer and conformed. The focal loss is used to fine-tune the model and improve the performance significantly. Finally, multiple trained models are integrated by casting vote to achieve our final 0.091 score.

SE-Harris and eSUSAN: Asynchronous Event-Based Corner Detection Using Megapixel Resolution CeleX-V Camera [article]

Jinjian Li, Chuandong Guo, Li Su, Xiangyu Wang, Quan Hu
2021 arXiv   pre-print
Event cameras are novel neuromorphic vision sensors with ultrahigh temporal resolution and low latency, both in the order of microseconds. Instead of image frames, event cameras generate an asynchronous event stream of per-pixel intensity changes with precise timestamps. The resulting sparse data structure impedes applying many conventional computer vision techniques to event streams, and specific algorithms should be designed to leverage the information provided by event cameras. We propose a

The proposed eSUSAN extracts the univalue segment assimilating nucleus from the circle kernel based on the similarity across timestamps and distinguishes corner events by the number of pixels in the nucleus area. Moreover, eSUSAN is fast enough to be applied to CeleX-V, the event camera with the highest resolution available. Based on eSUSAN, we also propose the SE-Harris corner detector, which uses adaptive normalization based on exponential decay to quickly construct a local surface of active events and the event-based Harris detector to refine the corners identified by eSUSAN. We evaluated the proposed algorithms on a public dataset and CeleX-V data. Both eSUSAN and SE-Harris exhibit higher real-time performance than existing algorithms while maintaining high accuracy and tracking performance.

English

Fengling Guo, Jie Zhou, Chuandong Qi, Jiaping Fu, Jinping Wu
2022 African Journal of Microbiology Research  
In the springs of 2020 and 2021, with a temperature of 15°C, root rot on garlic were widespread in Enshi, Hubei Province, China. Based on micro-morphological and cultural characteristics, the pathogen was identified as a Fusarium sp. Further, based on multilocus (ITS, EF-1α) phylogenic data, the strains were identified as Fusarium oxysporum. Koch's postulates were thus fulfilled by pathogenicity tests on garlic seedlings cultured in vitro.

BoALMT1, an Al-Induced Malate Transporter in Cabbage, Enhances Aluminum Tolerance in Arabidopsis thaliana

Lei Zhang, Xin-Xin Wu, Jinfang Wang, Chuandong Qi, Xiaoyun Wang, Gongle Wang, Mingyue Li, Xingsheng Li, Yang-Dong Guo
2018 Frontiers in Plant Science  
Aluminum (Al) is present in approximately 50% of the arable land worldwide and is regarded as the main limiting factor of crop yield on acidic soil. Al-induced root malate efflux plays an important role in the Al tolerance of plants. Here, the aluminum induced malate transporter BoALMT1 (KF322104) was cloned from cabbage (Brassica oleracea). BoALMT1 showed higher expression in roots than in shoots. The expression of BoALMT1 was specifically induced by Al treatment, but not the trivalent cations
more » ... lanthanum (La), cadmium (Cd), zinc (Zn), or copper (Cu). Subcellular localization studies were performed in onion epidermal cells and revealed that BoALMT1 was localized at the plasma membrane. Scanning Ion-selective Electrode Technique was used to analyze H + flux. Xenopus oocytes and Arabidopsis thaliana expressing BoALMT1 excreted more H + under Al treatment. Overexpressing BoALMT1 in transgenic Arabidopsis resulted in enhanced Al tolerance and increased malate secretion. The results suggested that BoALMT1 functions as an Al-resistant gene and encodes a malate transporter. Expressing BoALMT1 in Xenopus oocytes or A. thaliana indicated that BoALMT1 could increase malate secretion and H+ efflux to resist Al tolerance.

Purpose: Osteosarcoma is the most common primary malignancy of bone, and typically occurs among children and adolescence. This study aims to evaluate treatment outcomes among children, adolescents and young adults with osteosarcoma over the three decades by the changes in the long-term relative survival. Methods: Osteosarcoma incidence and relative survival data from Surveillance, Epidemiology, and End Results (SEER) registries during 1984-2013 were analyzed. The survival differences over three
more » ... decades, age, sex, race, and socioeconomic status (SES) were assessed by comparing Kaplan-Meier curves. Results: The overall incidence of osteosarcoma kept relatively stable with 0.4 per 100 000 in the three decades with the peak incidence occurring in the aged 10-19 group. The 10-year relative survival rate (RSR) increased from 57.7% to 61.0% in the three decades, with the greatest increase in the aged 0-9 group from 48.2% to 65.7%. The 10-year RSR improved from 54.1% to 61.5% in males, and from 62.4% to 63.0% in females, respectively, in the three decades. Furthermore, survival dramatically improved from 30% to 60% in the high-poverty group over the three decades. Conclusion: This study demonstrated that the overall incidence of osteosarcoma remained stable, with an improvement in survival in the three decades. The improved survival was greater in males than in females in the three decades. Furthermore, the survival significantly increased in high-poverty group, which was attributed to increasing improved health care system and patients with low finance can also have access to receiving effective and consistent treatment without distinction.

Organic acids promote phosphorus release from Mollisols with different organic matter contents

Xiaoyan Yang, Chuandong Zhang, Haiping Gu, Xiangwei Chen, Erhui Guo
2020 Soil and Water Research  
Organic acids could improve the phosphorus (P) availability through enhancing the release of inorganic phosphorus (P<sub>i</sub>) in the soil. However, the effects of organic acids on the P<sub>i</sub> release are still poorly understood, especially from soils with different organic matter contents. Here, a biochemically produced humic acid and P fertiliser were added to the soil to modify the content of the soil organic matter (SOM) and soil P, respectively. And then the soil samples were

The release of P<sub>i</sub> fractions (such as H<sub>2</sub>O-P<sub>i</sub>, NaHCO<sub>3</sub>-P<sub>i</sub>, NaOH-P<sub>i</sub>, HCl-P<sub>i</sub>, and Residual-P) from the soils with different organic matter contents in the presence of citric, oxalic, and malic acids was evaluated using a sequential chemical fractionation method. The results showed that the release of the NaHCO<sub>3</sub>-P<sub>i</sub>, NaOH-P<sub>i</sub>, and HCl-P<sub>i</sub> fractions also showed a decreasing trend with an increasing content of soil organic matter, and more NaOH-P<sub>i</sub> than the other P<sub>i</sub> fractions was generally released in the presence of organic acids. Considering the types of organic acids, oxalic acid and malic acid most effectively and least effectively released P<sub>i</sub>, respectively. The path analysis indicated that the NaOH-P<sub>i</sub> release had the highest direct and indirect effects on the total inorganic P (TP<sub>i</sub>) release. NaOH-P<sub>i</sub> was, therefore, the most effective source of P<sub>i</sub> in the Mollisols.

2012 Oncology Reports  
Lapatinib is highly active against breast cancer with HER2 overexpression in preclinical and clinical settings. Constitutive activation of NF-κB is linked to proliferation and apoptosis in breast cancer cells. NF-κB can be activated by HER2 in breast cancer cells. However, the effect of lapatinib on NF-κB activity is not completely clear. In this study, we showed that lapatinib potently inhibited activation of NF-κB in HER2-overexpressing breast cancer cells, including SKBR3 and MDA-MB-453; but
more » ... not in non-HER2-overexpressing breast cancer cells, MDA-MB-231, MDA-MB-468 and MDA-MB-435. In addition, we established a model of acquired resistance to lapatinib by chronically challenging SKBR3 breast cancer cells with increasing concentrations of lapatinib. EMSA assays showed that there was decreased NF-κB activity in the resistant cells. Western blot analysis showed that lapatinib reduced the phosphorylation of IκB-α in a time-and dose-dependent manner in SKBR3 cells. Furthermore, the expression level of p-IκB-α protein was markedly decreased in the resistant cells, compared with the parental SKBR3 cells. Additionally, treatment with the PI3K inhibitor LY294002 dramatically inhibited activation of NF-κB in HER2overexpressing breast cancer cells. Moreover, LY294002 inhibited phosphorylation of Akt and IκB-α in SKBR3 cells. Our results suggest that lapatinib potently inhibits the activation of NF-κB in HER2-overexpressing breast cancer cells. Lapatinib appears to inactivate NF-κB through reducing phosphorylation of IκB-α via blocking the PI3K/Akt cascade.
