A Classifier-Driven Deep Learning Clustering Approach To Enhance Data Collection In Manets, Ali Abdullah Ali, Mohammed Khaleel Hussein, Mohammed Ahmed Subhi Sep 2024

A Classifier-Driven Deep Learning Clustering Approach To Enhance Data Collection In Manets, Ali Abdullah Ali, Mohammed Khaleel Hussein, Mohammed Ahmed Subhi

Mesopotamian Journal of CyberSecurity

The conventional clustering and routing approaches used in mobile ad hoc networks (MANETs) may fail to work effectively in a dynamic network environment where nodes are highly mobile and the traffic load may also vary significantly. These limitations result in negative effects such as high packet drop rates, delays in data transmission, and low delivery rates, which make these methods unfit for modern high-density networks. To overcome these issues, this paper proposes a new deep learning-based classifier for adaptive clustering in MANETs. Through the use of machine learning algorithms, the proposed method is able to adapt to node clustering through …

While both the insurrectionists and the OAS and its adherents were ultimately unsuccessful, for members of a stable, functioning military to even contemplate such dire political action, these events illustrated a profound breach of military …


Exploiting The Heavy Chain Glycans For The Improvement Of Radioimmunoconjugates, Cindy Rodriguez Sep 2024

Exploiting The Heavy Chain Glycans For The Improvement Of Radioimmunoconjugates, Cindy Rodriguez

Dissertations, Theses, and Capstone Projects

Radiolabeled antibodies have become indispensable tools in nuclear medicine. However, the natural roles of antibodies within the immune system mean that they have several intrinsic limitations as a platform for radiopharmaceuticals. A handful of recent preclinical studies suggest that binding by FcR and particularly FcyRI can affect the pharmacokinetic profiles of 89Zr-labeled radioimmunoconjugates. Fc receptors (FcR) are responsible for many of the interactions between immunoglobulins (IgG) and immune cells. In biomedicine, this interplay is critical to the activity of several types of immunotherapeutics; however, relatively little is known about how FcRs affect the in vivo performance of radiolabeled antibodies. Antibodies …
