Abstract

A critical requirement for automated driving systems is enabling situational awareness in dynamically changing environments. To that end vehicles will be equipped with diverse sensors, e.g., LIDAR, cameras, mmWave radar, etc. Unfortunately the sensing `coverage' is limited by environmental obstructions, e.g., other vehicles, buildings, people, objects etc. A possible solution is to adopt collaborative sensing amongst vehicles possibly assisted by infrastructure. This paper introduces new models and performance analysis for vehicular collaborative sensing and networking. In particular, coverage gains are quantified, as are their dependence on the penetration of vehicles participating in collaborative sensing. We also evaluate the associated communication loads in terms of the Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) capacity requirements and how these depend on penetration. We further explore how collaboration with sensing capable infrastructure improves sensing performance, as well as the benefits in utilizing spatio-temporal dynamics, e.g., collaborating with vehicles moving in the opposite direction. Collaborative sensing is shown to greatly improve sensing performance, e.g., improves coverage from 20% to 80% with a 20% penetration. In scenarios with limited penetration and high coverage requirements, infrastructure can be used to both help sense the environment and relay data. Once penetration is high enough, sensing vehicles provide good coverage and data traffic can be effectively `offloaded' to V2V connectivity, making V2I resources available to support other in-car services.

Abstract

Propolis is a sticky substance produced by honeybees (Apis mellifera) through the collection of plant resins, which they mix with secretions from their palate and wax glands. Propolis can inhibit tumor invasion and metastasis, thereby reducing the proliferation of tumor cells and inducing cell apoptosis. Previous research has shown that propolis has an inhibitory effect on skin squamous cell carcinoma A431 cells. Nevertheless, its inhibitory mechanism is unclear because of many significantly different Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways between the ethanol extract of the propolis (EEP) group and the control group of cells. In this study, the main components of EEP and the antitumor mechanism at an IC50 of 29.04 μg/mL EEP were determined via untargeted metabolomics determined using ultra high-performance liquid chromatography tandem mass spectrometry (UHPLC‒MS/MS), respectively. The results revealed 43 polyphenolic components in the EEP and 1052 metabolites, with 160 significantly upregulated and 143 significantly downregulated metabolites between cells treated with EEP and solvent. The KEGG enrichment results revealed that EEP significantly inhibited A431 cell proliferation via the steroid hormone biosynthesis and linoleic acid metabolism pathways. These findings may provide valuable insights for the development of targeted therapies for the treatment of cutaneous squamous cell carcinoma. [ABSTRACT FROM AUTHOR]

Abstract

Background: The purpose of this study was to explore the relationship between atrial fibrillation (AF), cerebral small vessel disease (CSVD), and ischemic stroke. Methods: Data were extracted from China's Third National Stroke Registry (CNSR‐III), which registered 15,166 patients in China. A total of 12,180 ischemic stroke patients were included excluding those diagnosed with TIA or without MRI. Logistic regression was to explore the relationship between AF, CSVD, and poor functional outcomes at 12‐month follow‐up. Cox regression is to explore AF, CSVD, and stroke recurrence as well as all‐cause mortality at 12‐month follow‐up. Results: The average age was 62.40 ± 11.22 years old, and 8362 (68.65%) were men at baseline. Patients with AF had an increased risk of stroke recurrence and all‐cause mortality at 12‐month follow‐up. Those with AF and CSVD imaging such as lacunes, white matter hyperintensity (WMH), and the presence of cerebral microbleeds (CMBs) had an increased risk of poor prognosis. And those with both AF and CSVD burden had an increased risk of worse prognosis at 12‐month follow‐up. Conclusion: Among Chinese patients with acute ischemic stroke, those with AF were associated with a higher risk of 12‐month mortality and stroke recurrence. When AF was combined with some CSVD imaging features such as lacunes, WMH, presence of CMBs or burdens, the 12‐month poor prognosis worsened. [ABSTRACT FROM AUTHOR]

Abstract

An electrochemical CO2 reduction reaction (CO2RR) is an effective way to reduce greenhouse gases by converting CO2 into high-value-added chemical products using electricity generated from renewable energy. In this paper, a Cu2O spherical catalyst was prepared by ascorbic acid reduction. The precipitated Cu-Ag spherical catalyst (P-CuO-Ag) was successfully prepared by calcining Cu2O-Ag with the introduction of an Ag component as the substrate. During the electrochemical reduction of CO2, the FE of the P-CuO-Ag catalyst for C2H4 at a potential of −1.1 V vs. RHE was as high as 39.8%, which was nearly twice that of the CuO catalyst, while the local current density JC2H4 for C2H4 reached 6 mA cm−2. The incorporation of Ag gives the spherical CuO catalyst higher electrochemical activity and better kinetic performance than the catalyst without Ag. [ABSTRACT FROM AUTHOR]
