Customer Churn Prediction In Telecommunication Industry Using Deep Learning, Samah Wael Fujo, Suresh Subramanian, Moaiad Ahmad Khder

Information Sciences Letters

Without proper analysis and forecasting, industries will find themselves repeatedly churning customers, which the telecom industry in particular cannot afford. A predictable model for customers will allow companies to retain current customers and to obtain new ones. Deep-BP-ANN implemented in this study using two feature selection methods, Variance Thresholding and Lasso Regression, in addition, our model strengthened by early stopping technique to stop training at right time and prevent overfitting. We compared the efficiency of minimizing overfitting between dropout and activity regularization strategies for two real datasets: IBM Telco and Cell2cell.

Asymptomatic And Pre-Symptoms Transmission Of Covid-19 In Heterogeneous Epidemic Network, H. A. A. El-Saka, Ayman Al-Dmour, Ibrahim Obaya

Information Sciences Letters

The diversity of the spread pattern of the Corona virus is one of the most important reasons for the seriousness of the virus. Therefore, in this paper, we present a fractional mathematical SEIAS model that studies many ways of spreading (asymptomatic and pre-symptoms transmission) with the hypothesis of the spread of the virus in a heterogeneous network of individuals. The system consists of nonlinear equations which formed in fractional order. And it turns out that the system has two equilibrium positions (free and endemic positions). We also calculated the disease prevalence threshold (R) within the network. The condition for the …

Direct Nose To The Brain Nanomedicine Delivery Presents A Formidable Challenge, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

This advanced review describes the anatomical and physiological barriers and mechanisms impacting nanomedicine translocation from the nasal cavity directly to the brain. There are significant physiological and anatomical differences in the nasal cavity, olfactory area, and airflow reaching the olfactory epithelium between humans and experimentally studied species that should be considered when extrapolating experimental results to humans. Mucus, transporters, and tight junction proteins present barriers to material translocation across the olfactory epithelium. Uptake of nanoparticles through the olfactory mucosa and translocation to the brain can be intracellular via cranial nerves (intraneuronal) or other cells of the olfactory epithelium, or extracellular …

Treatment Pattern Of Antiepileptic Drugs In Pediatric With Epilepsy, Dwajani S, Meghana Ks, Krithika S, Adarsh E

Pharmacology and Clinical Pharmacy Research

Studying drug utilization helps to develop twin concepts for therapeutic formulation and essential drug lists. The main preference of using Antiepileptic drug (AED) therapy is that patients can be seizure-free for their lifetime. Treating children with epilepsy remains a major challenge, despite having several AEDs. Hence, we aimed to study drug utilization patterns among pediatric patients with epilepsy. This prospective study was conducted on 150 patients lesser than 18 years of age, receiving antiepileptic drugs. A specially designed case record form was used to collect the data on socioeconomic status, disease data, and treatment details. The majority of the children …

Notas Para Una Teoría Glotopolítica, José Del Valle

Publications and Research

En este artículo se define la glotopolítica como perspectiva intelectual y se identifican sus posiciones teóricas en relación con el lenguaje. Esta definición, se afirma, supone una apuesta interdisciplinaria en la que la sociolingüística crítica busca activamente establecer relaciones dialógicas con disciplinas tales como la antropología, la filosofía, la historiografía o la sociología. En este sentido, el artículo aborda la visión del lenguaje del crítico literario y cultural galés Raymond Williams, y de las posibilidades metodológicas y teóricas que ofrece su concepto de palabras clave.

This article discusses the theoretical underpinnings of glottopolitical studies, defined as an intellectual perspective. Such …
