Efficient Task Offloading in Vehicular Fog Networks
Ihsan Ullah,Byung-Seo Kim 대한전자공학회 2024 IEIE Transactions on Smart Processing & Computing Vol.13 No.1
Vehicular fog computing (VFC) has emerged as the key enabler in reducing computation processing delays and relieving base station (fog node) workload by utilizing the underutilized resources of vehicles during peak traffic hours. The base station distributes computation tasks among the available fog nodes. In VFC, efficient task placement and judicious resource utilization that can provide timely computations to delay-intolerant applications within the strict latency budget are highly challenging. Therefore, this paper proposes an efficient resource utilization and task placement strategy in VFC to reduce the computation latency and network resource utilization. The fog node adopts the weighted max-min fair share (WMMFS) to prioritize the received computation tasks and distribute the tasks among the available vehicles based on tasks’ priority. An efficient strategy is devised where the high-priority tasks are offloaded toward the most reliable vehicles to uphold the QoS and QoE application. Extensive simulations showed that the proposed offloading scheme outperformed the random offloading scheme.

Bacteria of the genus Photorhabdus are nematodes (Heterorhabditidae) symbiont and highly entomopathogenic in nature. Present study was concerned to investigate the effects of Photorhabdus temperata M1021 and Photorhabdus luminescens TT01 on plant morphology and physiology (‘Dongjin-beyo’ and ‘waitoc’). A significant (p<0.05) increase in the plant growth attributes including total plant length, root length, biomass,and chlorophyll contents were observed after treatment with culture extracts. Moreover indole-3-acetic acid (IAA)production by respective bacteria was confirmed by GCMS analysis. IAA production through tryptophan independent pathway was confirmed in P. temperata M1021 and P. luminescens TT01. Phosphate solubilization capability was also investigated by growing them on pikovskaya (PVK)agar as well as on PVK liquid medium with pH 7 at 28±2oC for 14 days. IAA production and phosphate solubilization capability of these bacteria could be the potential factors for plant growth promotion.

This study examines the determinants of the green entrepreneurship intention of university undergraduate students. Specifically, the undergraduate students’ risk-taking propensity, environmental vision, and university conceptual support for green entrepreneurship are investigated as determinants for green entrepreneurship intention. We surveyed 212 undergraduate students from different universities in Daejeon, Korea, in October 2022 to empirically test the proposed relationships. A partial least squared(PLS) based structural equation modeling was conducted to test the proposed hypotheses. We found that the risk-taking propensity, environmental vision, and university conceptual support for the green entrepreneurship of undergraduate students have a significant positive effect on green entrepreneurship intention. Since green entrepreneurship is one of the emerging issues in the area of the green economy, therefore, the findings of this study have contributed to the literature to understand the determinants of green entrepreneurship. Furthermore, the current study offers insights to the practitioners to leverage the factors such as university conceptual support for green entrepreneurship to increase the students’ green entrepreneurship intentions.
Breast Mass Detected During Cardiac Stress Testing Which Led to Correct Diagnosis and Treatment

The incidental findings/artifacts identified on myocardial perfusion imaging (MPI) often warrant further evaluation to rule out possible malignant pathologies. In this case report, we describe an elderly lady who was advised to undergo MPI for cardiac risk stratification prior to a non-cardiac surgery. Her MPI showed a large-sized infarct. In addition, a nodule on the left side of her chest that demonstrated increased isotope uptake was identified incidentally. Further evaluation of this lesion revealed a histopathological diagnosis of intraductal carcinoma of the breast. This case highlights the importance of reporting and investigating all suspicious incidental MPI findings.
