The ocean is an important part of the ecosystem and is closely related to our lives. Detecting the status of algae in the ocean contributes to the protection of the marine environment. With the continuous development of target detection technology, small target detection tasks are gradually applied to the task of monitoring marine organisms. We use two-stage cascade RCNN with Res2Net, ResNeSt, CBNet, ConvNeXt and DetectoRS backbone. Secondly, data pre-processing was used with blur, motion blur, MixUp, random rotation and other data enhancements. Then the pseudo label training model is used as a pre-training model. And model ensemble is used to improve the inference results. Finally Post-processing is performed using reduced bbox. We conduct extensive experiments on the dataset and achieve the performance of 0.562.

Nowadays, with the development of industrial production technology, defect detection has become an indispensable part of industrial production. However, due to various types of products and defects, it can be extremely difficult to identify and locate those defects precisely and accurately. The current major trend in defect detection is using convolutional neural networks and semantic segmentation techniques to better minimize the error rate of human eye recognition and highly improve efficiency. Our work is based on semantic segmentation method and combines it with transfer learning technique enabling our model to train on a relatively small dataset without compromising the performance, and use CNN to firstly classify input images in order to further reduce the number of images to improve computational efficiency and accuracy. Then through incorporating state-of-the-art semantic segmentation model U-Net++, our model achieves the best performance compared to UNet under transfer learning scenario. We compare our model with the state-of-the-art U-Net. Then we use mIOU and pixel accuracy to measure the models’ performance under two scenarios. Results illustrated that through transfer learning scenario, our model achieves the highest scores over other methods.

Primary hyperhidrosis (PH) is a rare inherited disorder characterized by excessive sweating. It can affect any part of the body, but most commonly affects the axilla, palms of the hands, groin, chest, and soles of the feet. This paper comprehensively overviews current and potential diagnosis and management methods of PH from both medical and engineering perspectives. We also investigate how patients and society can live better with PH by non-invasive medical treatments and propose potential engineering and social interventions.

The turning movement count (TMC) is a salient data source used for design and planning of intersections including sign, and signal installation, timing setup, as well as traffic and capacity analysis. This work presents a typical framework for utilizing the TMC data with simulation of Urban MObility (SUMO) software to mimic realistic traffic scenarios for intersection evaluation and analysis. Due to safety and mobility concerns regarding school campus zones, three intersections around the San Jose State university are selected and their corresponding turning movement data are ported into SUMO for intersection evaluation during peak hours occurred between 8:00 - 9:00 a.m. The traffic parameters extracted from each intersection simulation with realistic scenario are vehicles waiting time, speed and network flow links which imply the effectiveness of utilizing proposed approach for decision making and targeting intersections for signal optimization.

With the aging of population and the advance of technology, handwritten numeral recognition system is sophisticated and widely used. However, due to the presence of different writing surfaces, postures and other factors, the performance of handwritten numeral recognition is limited. In this paper, we propose a new supervised recurrent neural network, which combines time and space for target location prediction on handwritten datasets. Our method is based on the YOLO framework, and combines a long and short term memory (LSTM) mechanism. Moreover, our method not only locates handwritten images, but also improves the classification accuracy. Extensive comparison with the state-of-the-art methods demonstrates that our method achieves both accuracy and robustness on handwritten datasets. Meanwhile, our method is effective with low computational cost.

Pre-trained language models allowed us to process downstream tasks with the help of fine-tuning, which aids the model to achieve fairly high accuracy in various Natural Language Processing (NLP) tasks. Such easily-downloaded language models from various websites empowered the public users as well as some major institutions to give a momentum to their real-life application. However, it was recently proven that models become extremely vulnerable when they are backdoor attacked with trigger-inserted poisoned datasets by malicious users. The attackers then redistribute the victim models to the public to attract other users to use them, where the models tend to misclassify when certain triggers are detected within the training sample. In this paper, we will introduce a novel improved textual backdoor defense method, named MSDT, that outperforms the current existing defensive algorithms in specific datasets. The experimental results illustrate that our method can be effective and constructive in terms of defending against backdoor attack in text domain.

China is rapidly moving into an aging society. The fast aging population and lack of necessary elderly care resources and organizational capacity make it necessary for policymakers to amass information about current elderly care resources, either in the public or private sector, and elderly care service demands, and make informed and intelligent policies to enable collaborative efforts from different social entities to deal with this new challenge. This paper studies elderly care data resources management practices in Northeast China and analyzes how the studied capital cities build platforms, select, gather, manage, and utilize elderly care data for elderly care policy making and service provision. These data come from different sources, have other formats, are normalized differently, and are owned by various social entities. To enable their standardization, compatibility, and efficient use, skills, collaborative methods, principles, and institutions are needed to constitute the conceptual framework for collaborative governance. The study shall extract lessons and experiences from the studied cases in the context of this theoretical guidance and develop policy recommendations for future digital-enabled elderly care practice.
