Faculty Research, Scholarly, and Creative Activity

The adaptive mechanical properties of soft and fibrous biological materials are relevant to their functionality. The emergence of the macroscopic response of these materials to external stress and intrinsic cell traction from local deformations of their structural components is not well understood. Here, we investigate the nonlinear elastic behavior of blood clots by combining microscopy, rheology, and an elastic network model that incorporates the stretching, bending, and buckling of constituent fibrin fibers. By inhibiting fibrin cross-linking in blood clots, we observe an anomalous softening regime in the macroscopic shear response as well as a reduction in platelet-induced clot contractility. Our …

Vehicular Traffic Flow Prediction Via Decentralized Federated Meta-Learning, Andrew Selvia, Ankur Singh, Wencen Wu

Faculty Research, Scholarly, and Creative Activity

Traffic flow prediction (TFP) has become a crucial problem for billions of people who rely on traffic predictions to optimize their travels every day. In this paper, we present a decentralized federated meta-learning (DFML) framework for traffic flow prediction. Within this framework, traffic detectors spread across a road system can form federations with nearby peers in order to predict traffic collaboratively. A node that assembles a federation assumes the role of receiver while the remainder are assigned as broadcasters. The broadcasters learn model parameters from local data and then broadcast those models to receivers, thereby enriching the available information from …

Library Philosophy and Practice (e-journal)

This study investigated the correlation between user satisfaction and library patronage among postgraduate students at Ladoke Akintola University of Technology, Ogbomoso, Oyo State, Nigeria. A questionnaire was developed for data collection and validated, demonstrating a good reliability, with a coefficient of 0.847 (84.7%) for library patronage and 0.823 (82.3%) for user satisfaction. 120 responses were obtained and analyzed based on descriptive statistics (percentage, mean, average mean, and standard deviation) as well as inferential (Pearson Product Moment Correlation) statistics. The findings revealed a significant correlation between library patronage and user satisfaction (r= 0.000c, N = 120, P < 0.05) among postgraduate students of the University. The study concluded that adequate library customer care services and prioritizing meeting the essential needs of postgraduate students would enhance their satisfaction and consequently increase their library patronage.
