Exploration of artworks is enjoyable but often time consuming. For example, it is not always easy to discover the favorite types of unknown painting works. It is not also always easy to explore unpopular painting works which looks similar to painting works created by famous artists. This paper presents a painting image browser which assists the explorative discovery of user-interested painting works. The presented browser applies a new multidimensional data visualization technique that highlights particular ranges of particular numeric values based on association rules to suggest cues to find favorite painting images. This study assumes a large number of painting images are provided where categorical information (e.g., names of artists, created year) is assigned to the images. The presented system firstly calculates the feature values of the images as a preprocessing step. Then the browser visualizes the multidimensional feature values as a heatmap and highlights association rules discovered from the relationships between the feature values and categorical information. This mechanism enables users to explore favorite painting images or painting images that look similar to famous painting works.

Although there has been an increased focus on reducing HIV prevalence in Black MSM, little attention has been given to how and why Black MSM are able to remain HIV-negative, beyond believing that they are lucky. The purpose of this qualitative study was to explore how Black MSM try to stay HIV-negative. Guided by constructivist grounded theory and a strengths-based approach, we conducted in-depth interviews to explicate how Black MSM demonstrate resilience by staying seronegative amidst high seroprevalence. Results from this study suggest that it is their perceptions of HIV risk that translate into protective strategies that enable them to prevent infection. Our study offers insight into their reasoning processes that guide their efforts to stay HIV-negative.The novel coronavirus has upended many traditional research procedures as universities and other research entities have closed to activate social distancing. Some social and behavioral research activities (e.g. data analysis, manuscript preparation) can be continued from other environments with appropriate security protocols in place. For studies involving in-person interactions, continuity may be more difficult. Phone-based interactions provide a low-tech solution that may suffice in some cases. Yet, videoconferencing platforms can nearly replicate in-person interactions, activating both auditory and visual senses and potentially resulting in more substantial engagement. Staff can meet with participants individually or in groups, each seeing and hearing one another in real time. This paper provides guidance for researchers transitioning in-person assessments and interventions to a synchronous videoconferencing platform. Best practices, key considerations, examples from the field, and sample protocols are presented to ease transition for ongoing studies and maximize the potential of videoconferencing-and social distancing.Anti-angiogenesis effect of ascorbic acid (AA) is still controversial. However, most of the scientific evidence suggests that AA has anti-angiogenesis effects on a number of test systems, including laboratory animals, human beings, and their derived cell lines. The information provided in this paper suggests that AA may be a hopeful angiostatic agent for the treatment of cancer.With the rapid development of deep learning technology, behavior recognition based on video streams has made great progress in recent years. However, there are also some problems that must be solved (1) In order to improve behavior recognition performance, the models have tended to become deeper, wider, and more complex. However, some new problems have been introduced also, such as that their real-time performance decreases; (2) Some actions in existing datasets are so similar that they are difficult to distinguish. To solve these problems, the ResNet34-3DRes18 model, which is a lightweight and efficient two-dimensional (2D) and three-dimensional (3D) fused model, is constructed in this study. The model used 2D convolutional neural network (2DCNN) to obtain the feature maps of input images and 3D convolutional neural network (3DCNN) to process the temporal relationships between frames, which made the model not only make use of 3DCNN's advantages on video temporal modeling but reduced model complexity. Compared with state-of-the-art models, this method has shown excellent performance at a faster speed. Furthermore, to distinguish between similar motions in the datasets, an attention gate mechanism is added, and a Res34-SE-IM-Net attention recognition model is constructed. The Res34-SE-IM-Net achieved 71.85%, 92.196%, and 36.5% top-1 accuracy (The predicting label obtained from model is the largest one in the output probability vector. If the label is the same as the target label of the motion, the classification is correct.) respectively on the test sets of the HMDB51, UCF101, and Something-Something v1 datasets.PURPOSE To investigate the functional and structural biomarkers and their correlation with Usher syndrome (USH). METHODS Medical records, imaging and electrophysiology test results of USH patients attending the Save Sight Institute between 2012 and 2017 were reviewed. Best corrected visual acuity (BCVA), ultra-widefield autofluorescence (UW-FAF), spectral-domain optical coherence tomography (SD-OCT), full-field electroretinogram and pattern electroretinogram (pERG) were performed. SD-OCT scans assessed central macular thickness (CMT), greatest linear diameter of preserved outer retinal layers-macular island (MI) and presence of cystoid macular edema (CME). UW-FAF images were qualitatively graded to identify hypo/hyperfluorescence patterns in the peripheral fundus. RESULTS Thirty-six eyes from 18 subjects were included. Mean BCVA was 0.22 ± 0.3 LogMAR. MI extent was significantly associated with better vision (β = - 0.175 per 1000 µm; R2 = 0.487; P = 0.002; Fig. 4). A higher pERG P50 was associated with a larger macular island (β = 782 per µV; R2 = 0.
