    Abstract Background: The outbreak of a new coronavirus, COVID-19, which was earliest reported in Wuhan, China, is now transmitting throughout the world. The aim of this study was to articulate the clinical characteristics of COVID-19 and to reveal possible factors that may affect the persistent time of positive SARS-CoV-2 nucleic acid test, so as to identify which patients may deteriorate or have poor prognoses as early as possible.
    Methods: Retrospective cohort study was carried out on 47 patients with confirmed COVID-19 infection admitted to XinYu People's Hospital of JiangXi Province. Epidemiological, demographic, clinical, laboratorial, management, treatment, and outcome data were also collected and analyzed.
    Results: In this study, patients were divided into two groups based on whether their SARS-CoV-2 nucleic acid tests in respiratory specimens turn negative within (Group Rapid or Group R) or over (Group Slow or Group S) a week. There was no significant difference in age, sex, travel or exposure history, and smoking history between the two groups. Forty-two patients had been observed with comorbidities. Similar clinical manifestations, for instance fever, cough, sputum, and fatigue, have been observed among patients in both groups, except that patients in Group S were obviously more likely to get fatigue than patients in Group R. Both groups had shown decrease in white blood cell or lymphocyte counts. Chest X-ray or computed tomography scan showed unilateral or bilateral infiltrates. High proportion in both groups has used nasal cannula (89.47% vs. 85.71%) to inhale oxygen. 10.53% of Group S have applied high-flow nasal cannula, while Group R used none. The current treatment is mainly antibiotics, antiviral, and traditional Chinese medicine, while a couple of patients has used methylprednisolone. Only 1 patient out of both groups got even worse despite this active treatment.
    Conclusion: Clinical characteristics of COVID-19 include the exposure history and typical systemic symptoms such as fever, cough, fatigue, decreased WBC and lymphocyte counts, and infiltration in both lower lobes on CT imaging. Among them, fatigue appears to be an important factor that affects the duration of positive SARS-CoV-2 nucleic acid test in respiratory specimens.

    Abstract With the rapid development of deep neural networks(DNNs), many robust blind watermarking algorithms and frameworks have been proposed and achieved good results. At present, the watermark attack algorithm can not compete with the watermark addition algorithm. And many watermark attack algorithms only care about interfering with the normal extraction of the watermark, and the watermark attack will cause great visual loss to the image. To this end, we propose DiffWA, a conditional diffusion model with distance guidance for watermark attack, which can restore the image while removing the embedded watermark. The core of our method is training an image-to-image conditional diffusion model on unwatermarked images and guiding the conditional model using a distance guidance when sampling so that the model will generate unwatermarked images which is similar to original images. We conducted experiments on CIFAR-10 using our proposed models. The results shows that the model can remove the watermark with good effect and make the bit error rate of watermark extraction higher than 0.4. At the same time, the attacked image will maintain good visual effect with PSNR more than 31 and SSIM more than 0.97 compared with the original image.

    Abstract Music information retrieval (MIR) has gone through an explosive development with the advancement of deep learning in recent years. However, music genres like electronic dance music (EDM) has always been relatively less investigated compared to others. Considering its wide range of applications, we present a Python package for automated EDM audio generation as an infrastructure for MIR for EDM songs, to mitigate the difficulty of acquiring labelled data. It is a convenient tool that could be easily concatenated to the end of many symbolic music generation pipelines. Inside this package, we provide a framework to build professional-level templates that could render a well-produced track from specified melody and chords, or produce massive tracks given only a specific key by our probabilistic symbolic melody generator. Experiments show that our mixes could achieve the same quality of the original reference songs produced by world-famous artists, with respect to both subjective and objective criteria. Our code is accessible in this repository: https://github.com/Gariscat/loopy and the official site of the project is also online https://loopy4edm.com .
