This paper presents a technique for obtaining an exact solution for the well-known Laguerre’s differential equations that arise in the modeling of several phenomena in quantum mechanics and engineering. We utilize an efficient procedure based on the modified Adomian decomposition method to obtain closed-form solutions of the Laguerre’s and the associated Laguerre’s differential equations. The proposed technique makes sense as the attitudes of the acquired solutions towards the neighboring singular points are correctly taken care of.

The incidence of esophageal adenocarcinoma (EAC) has dramatically increased in the United States as well as Western European countries. The majority of esophageal adenocarcinomas arise from a backdrop of Barrett’s esophagus (BE), a premalignant lesion that can lead to dysplasia and cancer. Because of the increased risk of EAC, GI society guidelines recommend endoscopic surveillance of patients with BE. The emphasis on early detection of dysplasia in BE through surveillance endoscopy has led to the development of advanced endoscopic imaging technologies. These techniques have the potential to both improve mucosal visualization and characterization and to detect small mucosal abnormalities which are difficult to identify with standard endoscopy. This review summarizes the advanced imaging technologies used in evaluation of BE.

A key requirement of today’s fast changing business outcome and innovation environment is the ability of organizations to adapt dynamically in an effective and efficient manner. Becoming a data-driven decision-making organization plays a crucially important role in addressing such adaptation requirements. The notion of “data democratization” has emerged as a mechanism with which organizations can address data-driven decision-making process issues and cross-pollinate data in ways that uncover actionable insights. We define data democratization as an attitude focused on curiosity, learning, and experimentation for delivering trusted data for trusted insights to a broad range of authorized stakeholders. In this paper, we propose a general indicator framework for data democratization by highlighting success factors that should not be overlooked in today’s data driven economy. In this practice-based research, these enablers are grouped into six broad building blocks: 1) “ethical guidelines, business context and value”, 2) “data leadership and data culture”, 3) “data literacy and business knowledge”, 4) “data wrangling, trustworthy & standardization”, 5) “sustainable data platform, access, & analytical tool”, 6) “intelligent data governance and privacy”. As an attitude, once it is planned and built, data democratization will need to be maintained. The utility of the approach is demonstrated through a case study for a Cameroon based start-up company that has ongoing data analytics projects. Our findings advance the concepts of data democratization and contribute to data free flow with trust.

Glucagon like peptide-1 is responsible for the incretin effect after a meal or an oral glucose load. Patients with type 2 diabetes mellitus have impairment of secretion and action of glucagon like peptide-1. This impairment can be overcome through pharmacological doses of glucagon like peptide-1 analogues. Aim of the Study: This study aimed at evaluation of the effect of treatment with glucagon like peptide-1 analogues;liraglutide and dulaglutide, in Emirati patients with type 2 diabetes mellitus. Glycemic control was the primary end point while the secondary end point was the effect on body mass index, blood pressure, heart rate, serum creatinine, lipid profile and estimated glomerular filtration rate. Patients & Methods: This is a retrospective study including 54 patients with type 2 diabetes mellitus. Patients used Liraglutide or Dulaglutide as add on therapy to oral antidiabetic medications for one year. Thirty-four patients used liraglutide 1.8 mg once daily and 20 patients used dulaglutide 1.5 mg once weekly. All patients were older than 18 years and had estimated glomerular filtration rate (>90 ml/min/1.73 m2). Body mass index, sitting blood pressure and heart rate were collected. Fasting plasma glucose, HbA1c, lipid panel and other biochemical parameters were also collected. Data were analysed before and at 6 and 12 months of glucagon like peptide-1 analogue treatment. Results: At 12 months of treatment, liraglutide significantly reduced fasting plasma glucose (11.3 ± 4 vs 7 ± 1.7, p < 0.001), HbA1c (8.55 ± 1.6 vs 7.18 ± 1.04, p < 0.001) and body mass index (39.4 ± 6.4 vs 37.6 ± 6.7, p < 0.0005). Dulaglutide did not significantly reduce fasting plasma glucose (15.4 ± 3.5 vs 9.5 ± 5.4 mmol/L, p = 0.053), significantly reduced HbA1c (8.84 ± 1.8 vs 7.5 ± 0.79, p = 0.007), body mass index (38.8 ± 6.8 vs 37.2 ± 6.6, p
