Ustnlp16 at SemEval-2025 Task 9: Improving Model Performance through Imbalance Handling and Focal Loss [PDF]

open access: yesarXiv
Classification tasks often suffer from imbal- anced data distribution, which presents chal- lenges in food hazard detection due to severe class imbalances, short and unstructured text, and overlapping semantic categories. In this paper, we present our system for SemEval- 2025 Task 9: Food Hazard Detection, which ad- dresses these issues by applying ...

Cyber Food Swamps: Investigating the Impacts of Online-to-Offline Food Delivery Platforms on Healthy Food Choices [PDF]

open access: yesarXiv
Online-to-offline (O2O) food delivery platforms have greatly expanded urban residents' access to a wide range of food options by allowing convenient ordering from distant food outlets. However, concerns persist regarding the nutritional quality of delivered food, particularly as the impact of O2O food delivery platforms on users' healthy food remains ...

Geometric Adjustment of T Cell‐Sensitive Nanorobots for Enhanced Stability

open access: yesAdvanced Healthcare Materials, EarlyView.
For the long‐term use of live dendritic cell (DC)‐based vaccines, nano bone marrow dendritic cell (BMDC) originated T cell activators (nano‐BOTs) are synthesized. The geometric properties of nanoparticles are precisely modulated, enhancing their stability and T cell activation capacity.
