Objectives: In conditional automation for automated vehicles (AVs), drivers are tasked with remaining vigilant and ready to assume control should the system encounter a malfunction. However, little to no information is provided to the driver either about the AV's intended maneuvers or the AV's awareness of potential threats in the surrounding environment. To address this research gap, the present study proposes 2 human-machine interaction (HMI) concepts: Firstly, the shared intended pathway (SIP), which presents a forecast of the AV's intended maneuvers and, secondly, object recognition bounding boxes (ORBBs), which place transparent blue squares around other road users likely to contribute to a crash.

Metformin (MET) can be an alternative therapeutic strategy for managing ocular burn primarily because of its pleiotropic mechanism. Longer retention on the ocular surface and sustained release are necessary to ensure the efficacy of MET for ocular application. Although the high aqueous solubility of MET is good for formulation and biocompatibility, it makes MET prone to high nasolacrimal drainage.

Article Synopsis
  • Cisplatin is a common chemotherapy treatment for advanced-stage oral squamous cell carcinoma (OSCC), but it can lead to the cancer coming back or spreading because cells can become resistant to it.
  • Scientists are investigating a substance called piperlongumine (PL) that could help make cancer cells more sensitive to cisplatin, but it has some challenges with being used as a medicine.
  • To make it work better, researchers created special nanoparticles (smart PL-NPs) that can deliver PL directly to cancer cells, helping to stop drug resistance and reduce tumor growth in models like mice and zebrafish.
