Spectrum sharing disruption in cognitive radio networks (CRNs) can significantly degrade network performance.Most sharing disruption attacks in the literature focus on orthogonal multiple access (OMA) or higher layers, such as medium access control (MAC).However, this paper focuses on multi-copyright cognitive radio non-orthogonal multiple access (
Background/Objective: Collision tumors composed of craniopharyngiomas and Turners pituitary adenomas are extremely rare.We report a collision tumor formed by a papillary craniopharyngioma and a growth hormone-secreting pituitary adenoma, which is the first report of such a tumor, to the best of our knowledge.Case Report: A 49-year-old man presented
Longwall gateroad entries are subject to changing horizontal and vertical stress induced by redistribution of loads around the extracted panel.The stress changes can result in significant deformation of the entries that may include roof sag, rib dilation, and floor heave.Mine operators install different types of supports to control the ground respo
