Social media sites have appeared during the last 10 years and their use has exploded all over the world. Twitter is a microblogging service that has currently 320 million user profiles and over 100 million daily active users. Many celebrities and leading politicians have a verified profile on Twitter, including Justin Bieber, president Obama, and the Pope. In this paper we investigate the '‘hun...

the study was designed to investigate the comparative analysis of agricultural credit users and non-users among cassava farmers in ohafia local government area of abia state. a sample of 50 credit users and 50 non-credit user cassava-based farmers were selected by multistage random sampling technique. data were collected with a well structured questionnaire administered to a total of 100 random...

I thank Dean Martin for his very flattering introduction. I thank the College for bestowing a chair to me and the Mathematics Department for providing a wonderful atmosphere for my work. I thank Don Lewis and my current and former colleagues for their support. I take this opportunity to also thank my family, friends, and collaborators. My mathematical horizon has widened considerably after join...

We derive diierent representations of compact QED xed to Lan-dau gauge by the lattice Faddeev-Popov procedure. Our analysis nds that (A)Nielsen-Olesen vortices arising from the compactness of the gauge-xing action are quenched , that is, the Faddeev-Popov determinant cancels them out and they do not innuence correlation functions such as the photon propagator; (B)Dirac strings are responsible f...

Upon release, Pokemon Go, an augmented reality technology based game garnered tremendous interest in the public, with an average of 20 million daily active users. The game combines geo-spatial elements along with gamification practices to incentivize it’s users movement in the physical world. Such incentives can have potential externalities to businesses associated with them. Using online revie...

This study analyzes mobile phone data derived from 10 million daily active users across the United States to better understand the spatio-temporal activity patterns of users in Central Park, New York. The aim of this initial investigation is to create quantifiable measures for understanding public space usage in regions of the city that have no natural data source for measuring activity. We ana...

We prove that for any positive integers n and k such that n≥ k≥ 1, there exists an [n, k] generalized Reed-Solomon (GRS) code that has a sparsest and balanced generator matrix (SBGM) over any finite field of size q ≥ n+ ⌈ k(k−1) n ⌉, where sparsest means that each row of the generator matrix has the least possible number of nonzeros, while balanced means that the number of nonzeros in any two c...
