Communication infrastructure is damaged by disasters and it is difficult to support communication services in affected areas. UAVs play an important role in the emergency communication system. Due to the limited airborne energy of a UAV, it is a critical technical issue to effectively design flight routes to complete rescue missions.

Indoor localization problems are difficult due to that the information, such as WLAN and GPS, cannot achieve enough precision for indoor issues. This paper presents a novel indoor localization algorithm, GeoLoc, with uncertainty eliminate based on fusion of acceleration, angular rate, and magnetic field sensor data. The algorithm can be deployed in edge devices to overcome the problems of insufficient computing resources and long delay caused by high complexity of location calculation.

Article Synopsis
  • - The study investigated infection rates in patients with systemic lupus erythematosus (SLE) undergoing different dosages of intravenous cyclophosphamide (IV-CYC) treatment.
  • - Out of 1022 SLE patients, those on a lower-dose, short-interval IV-CYC regimen showed a significantly reduced infection rate compared to those on a higher-dose regimen (13.04% vs 22.27%).
  • - Key findings indicated that respiratory and skin infections were less common in the lower-dose group, and infections were more likely in patients with certain risk factors, such as lower white blood cell counts and higher glucocorticoid doses.

Article Synopsis
  • - The study aimed to explore how glucosides of chaenomeles speciosa (GCS) impact brain injury caused by ischemia/reperfusion in mice, assessing various factors like cell morphology, neurological activity, and apoptosis.
  • - Fifty C57BL/C mice were divided into five groups to receive different treatments, showing that GCS significantly improved brain tissue condition by reducing cell damage and inflammation, especially at a dosage of 60 mg/kg.
  • - Results indicated that GCS works by inhibiting specific inflammatory pathways (NF-κB P65 and TNF-α), leading to decreased oxidative stress and cell death in the brain injury model, suggesting its potential as a therapeutic agent.
