Application of power-law committee machine to combine five machine learning algorithms for enhanced oil recovery screening.

One of the main challenges in screening of enhanced oil recovery (EOR) techniques is the class imbalance problem, where the number of different EOR techniques is not equal. This problem hinders the generalization of the data-driven methods used to predict suitable EOR techniques for candidate reservoirs. The main purpose of this paper is to propose a novel approach to overcome the above challenge by taking advantage of the Power-Law Committee Machine (PLCM) technique optimized by Particle Swam Optimization (PSO) to combine the output of five cutting-edge machine learning methods with different types of learning algorithms.

Do Health Literacy and Awareness of Polycystic Ovary Syndrome Predict the Lifestyle Choices of Arabic-Speaking Female University Students.

Background: Considering the increasing prevalence of Polycystic Ovarian Syndrome (PCOS) and its related complications-such as obesity, cardiovascular diseases, and infertility-in the Middle East, it is imperative to create sufficient public awareness about this issue. Accordingly, the potential link between PCOS awareness and health literacy level with the lifestyle choices of Arabic-speaking female university students was examined in this cross-sectional study.

Materials And Methods: This research was conducted in the Sultanate of Oman and involved 446 Arabic-speaking female university students, who completed a self-administered online questionnaire, Single Item Literacy Screener, and PCOS Awareness Tool.

Upper Blepharoplasty: An Evidence-Based Assessment of Preoperative Considerations and Surgical Techniques.

Upper blepharoplasty is one of the most common facial plastic surgical procedures performed. Due to its growing popularity, an abundance of articles is available describing variations in the surgical technique and outcomes. As a result, it has become increasingly difficult to identify appropriate surgical literature validated by a high level of evidence.

Eyebrow Position Before and After Enucleation.

Methods: In this observational cohort study, medical records and photographs were reviewed in patients undergoing surgery between 2005 and 2020.

Development of large-scale microalgae production in the Middle East.

Microalgae in the Middle East can theoretically address food security without competing for arable land, but concerns exist around scalability and durability of production systems under the extreme heat. Large-scale Chlorella sorokiniana production was developed in outdoor raceway ponds in Oman and monitored for 2 years to gather data for commercial production. Biological and technical challenges included construction, indoor/outdoor preculturing, upscaling, relating productivity to water temperature and meteorological conditions, harvesting, drying, and quality control.

Smartphone-based Anterior Segment Imaging: A Comparative Diagnostic Accuracy Study of a Potential Tool for Blindness Prevalence Surveys.

Purpose: To determine if smartphone photography could be a useful adjunct to blindness prevalence surveys by providing an accurate diagnosis of corneal opacity.

Methods: A total of 174 patients with infectious keratitis who had undergone corneal culturing over the past 5 years were enrolled in a diagnostic accuracy study at an eye hospital in South India. Both eyes had an ophthalmologist-performed slit lamp examination, followed by anterior segment photography with a handheld digital single lens reflex (SLR) camera and a smartphone camera coupled to an external attachment that provided magnification and illumination.

Comparison of Smartphone Photography, Single-Lens Reflex Photography, and Field-Grading for Trachoma.

Conjunctival examination for trachomatous inflammation-follicular (TF) guides public health decisions for trachoma. Smartphone cameras may allow remote conjunctival grading, but previous studies have found low sensitivity.

Evaluation of the Efficacy and Safety of Switching to Pasireotide in Patients With Acromegaly Inadequately Controlled With First-Generation Somatostatin Analogs.

Acromegaly is a rare, serious endocrine disorder characterized by excess growth hormone (GH) secretion by a pituitary adenoma and overproduction of insulin-like growth factor I (IGF-I). Transsphenoidal surgery is the treatment of choice, although many patients require additional interventions. First-generation somatostatin analogs (SSAs) are the current standard of medical therapy; however, not all patients achieve control of GH and IGF-I.

Association between biochemical control and comorbidities in patients with acromegaly: an Italian longitudinal retrospective chart review study.

Purpose: Achieving biochemical control (normalization of insulin-like growth factor-1 [IGF-1] and growth hormone [GH]) is a key goal in acromegaly management. However, IGF-1 and GH fluctuate over time. The true potential impact of time-varying biochemical control status on comorbidities is unclear and relies on multiple, longitudinal IGF-1 and GH measurements.
