Performance Based Scheduling In Distributed Mixed Criticality Systems, Amjad Ali, Saud Wasly, Asad Masood Khattak, Ihsan Ali, Shahid Iqbal, Bashir Hayat

All Works

With a focus on computationally intensive, distributed, and parallel workloads, scheduling in mixed-criticality distributed systems presents significant challenges due to shared memory and resources, as well as the diverse demands of tasks. The system’s efficiency is heavily dependent on the overall scheduling duration (make span), while individual task deadlines impose strict timing constraints. When the tasks need to simultaneously access the shared memory, then these tasks interfere the execution of one another. For managing the scheduling of interfering tasks in distributed mixed-criticality systems, a novel Interference-Aware Partitioning Fixed Priority (IAP-FP) approach is proposed, which effectively handles task partitioning among cores …

The Discovery Of P62-Dependent Processing Bodies, Elizabeth Barrow

Peninsula Medical School Theses

The cellular degradation process autophagy can be a selective process during which, cellular components, such as excess proteins, can be marked for degradation by the post translational modification ubiquitination. Proteins that act as selective autophagy receptors can recognise the ubiquitinated substrates and target them to the selective autophagy pathway, facilitating their degradation and thereby mediating cellular homeostasis. The selective autophagy receptor Sequestome 1 (p62) undergoes liquid-liquid phase separation (LLPS) to form p62 bodies to mediate the autophagic degradation of ubiquitinated proteins. At the time of this research, it was unknown whether p62 could exist in a differential droplet form to …
