Summary: This study proposes a method combining deep learning and image analysis to accurately identify veraison in colored wine grapes under natural field growing conditions. The study utilizes semantic segmentation model for background removal and constructs a Mask R-CNN instance segmentation pipeline with optimized anchor parameters. The ResNet50-FPN backbone network performs the best in Mask R-CNN. Additionally, a method for characterizing berry veraison using the H component of HSV color space is proposed and an algorithm is developed to identify veraison progress based on the percentage of berries in different grades. The proposed method achieves high test accuracy and can provide important reference for automated monitoring and intelligent management decisions of grape growth.

Summary: The study utilized deep learning to predict the leaf phenology of deciduous broadleaf forests at 56 sites in North America using PhenoCam images. In the one-site experiment, high accuracy was achieved, but lower accuracies were observed in the all-site experiment. The model's accuracy improved when deep networks used region of interest images as inputs instead of entire images.

Summary: Chinese firms' increasing cross-border acquisitions challenge existing theories of multinational enterprise due to unique characteristics and government involvement. Our study shows that firms with more government ownership have better post-CBA performance, but this relationship is influenced by firm-level and country-level boundary conditions.

Summary: Australia, specifically the southern Murray-Darling Basin, has the most advanced water market in the world. This study identified five clusters of irrigators in the region, including those trying to expand the farm, diversify, downsize, transition, and save water. The findings suggest a trend of irrigation farm exit, particularly among older farmers facing financial and/or psychological stress, due to the predicted rise in temperature caused by climate change.

Summary: With the acceleration of urbanization, waste classification has become an inevitable factor threatening the environment and human health. Through a questionnaire survey, we found that the elderly, women, and people with higher education are more likely to participate in waste classification. Attitude, collaborative governance, and institutional pressure positively affect waste classification behavior, while subjective norm and infrastructure have a negative effect.

Summary: This study examines the convergence of telecommunication infrastructures in 205 countries from 2000 to 2018. The findings suggest that there is panel convergence for the full sample, developed, less developed, upper-middle and high-income countries, while low- and lower-middle-income countries diverge. The System GMM results further suggest that economic, human capital, financial deepening and demographic factors play a significant positive role in telecommunication infrastructure convergence across countries.

Summary: This study used machine learning algorithms to identify important variables associated with mortality risk in dementia patients. They found that age, sex, body mass index, mini-mental state examination score, time periods before and after diagnosis were significant predictors of mortality risk. The study also discovered new variables not previously reported to be associated with mortality in dementia. These findings demonstrate the potential of machine learning algorithms in predicting mortality risk in clinical settings.

Summary: Breast cancer is the most commonly diagnosed female malignancy worldwide. Recent developments in deep convolutional neural networks have shown promising performance for breast cancer detection and classification. However, biased features can be learned due to variations in appearance and small datasets. To address this issue, a densely connected convolutional network (DenseNet) was trained using texture features representing different physical morphological representations as inputs. The use of connectivity estimation and nearest neighbors improved the network's unbiased prediction. The approach achieved higher diagnostic accuracy and provided visual explanations for model predictions.

Summary: Learning-based super resolution has made remarkable progress in improving image quality, but the performance decreases when the degradation kernel changes. Blind SR networks can estimate the degradation kernel and adapt well in realistic scenarios, improving performance and runtime. This paper proposes a design that imposes constraints for the kernel estimation network in both the image domain and kernel domain, resulting in high-quality images and efficient runtime.
