Hybrid fuzzy inference rules of descent method and wavelet function for volatility forecasting.

This research employs the gradient descent learning (FIR.DM) approach as a learning process in a nonlinear spectral model of maximum overlapping discrete wavelet transform (MODWT) to improve volatility prediction of daily stock market prices using Saudi Arabia's stock exchange (Tadawul) data. The MODWT comprises five mathematical functions and fuzzy inference rules.

Traumatic Enthesophyte From a Chronic Pectoralis Major Tendon Rupture: A Case Report.

Case: A 24-year-old active duty soldier with a chronic pectoralis major tendon rupture presented a year later with a bony lesion consistent with an enthesophyte at the humeral insertion. The patient continued to have pain that was affecting his activities of daily living and underwent surgical intervention.

Conclusion: Operative management with enthesophyte excision and pectoralis major tendon repair provided relief to the patient's symptoms and return to preinjury levels of function as evaluated with Tegner, single assessment numeric evaluation, and visual analog scale scores at the 2-year follow-up.

A novel investigation of the influence of corporate governance on firms' credit ratings.

Corporate governance is the way of governing a firm in order to increase its accountability and to avoid any massive damage before it occurs. The aim of this paper is to investigate the impact of capital structure, firms' size, and competitive advantages of firms as control variables on credit ratings. We investigate the role of corporate governance in improving the firms' credit rating using a sample of Jordanian listed firms.

Predicting success: A comparative analysis of student performance on the surgical clerkship and the NBME surgery subject exam.

Background: The National Board of Medical Examiners surgery shelf is a well-established terminal measure of student medical knowledge. No study has explored the correlation between intraclerkship quizzes and shelf exam performance.

Methods: Weekly quiz and National Board of Medical Examiners scores were collected from 156 third-year students who participated in a 12-week surgical clerkship from 2015 to 2017.

A 5-Year History of Laparoscopic Gastric Band Removals: an Analysis of Complications and Associated Comorbidities.

Objective: This study was undertaken to examine the factors contributing to laparoscopic adjustable gastric band (LAGB) removals among adults > 18 years of age. We hypothesized that female patients with multiple comorbidities would have increased removals.

Design: This retrospective exploratory study uses internal records and standard statistical methods of analysis.
