It is widely accepted that houses in better-designed neighborhoods are found to enjoy a price premium. Prior studies have mainly examined the impact of macro-level neighborhood attributes (e.g., park accessibility using land use data) on housing prices. More recently, research has investigated micro-level features street view imagery (SVI) data, though scholars limited scope objective indicators such as green index and sky index. The role subjectively measured qualities less discussed due...

Person re-identification is the task of identifying pedestrians across different cameras. Domain adaptation person involves transferring knowledge from labeled source domains to unlabeled target domains, with applications in security and surveillance. Challenges emerge due variations sample quality disparities distance distribution between positive negative pairs. To address these challenges, this paper proposes a guided metric learning approach for domain re-identification. We focus on...

The recognition accuracy of the pedestrian re-identification algorithm is affected by factors such as scale, posture, occlusion level, and appearance a in an image. These bring great challenges to further development deep learning theory field person re-identification. On one hand, existing model cannot accurately extract attention information containing contextual discriminative features. other images same taken with different cameras have problem degrees occlusion. Therefore, we introduce...

There are many studies on the advantages of using mesenchymal stem cells (MSCs) that secrete various paracrine factors for repairing endometrial injury. However, stability and effectiveness MSCs require improvement to become a viable therapy. Hepatocyte growth factor (HGF), one cytokines secreted by MSCs, promotes vascular repair epithelial transformation (MET). Therefore, HGF likely process endometrium. We prepared transfected with gene explore its effects mechanism damaged endometrium...
