Fixed start method for repetitive project scheduling with simulated annealing.

This research deals with the high project completion variability by presenting a new method to decrease such variability in repetitive construction projects. To achieve this, a Fixed Start Method (FSM) -where the starts of each activity with a high level of probabilistic confidence for the planned project duration are fixed- was applied, where the high level of probabilistic confidence obtained was optimized with the use of the metaheuristic algorithm called Simulated Annealing (SA). This procedure evaluated the project completion in a case study based on the coefficient of variance (COV) of the resulting standard deviation, mean, and temperature selected for the SA.

Intrapericardial Corticosteroids and Colchicine Prevent Pericarditis and Atrial Fibrillation After Epicardial Ablation of Ventricular Arrhythmias.

Background: Postprocedural pericarditis (PP) can occur in up to 29.4% of patients undergoing epicardial catheter ablation of ventricular tachycardia (VT). Despite several proposed strategies to mitigate this adverse outcome, rates of PP and pericarditic pain remain high.

Refractance Window Drying: A New Approach For Producing High-Quality Powdered Dairy Products.

Refractance window drying is an emerging technology that allows the development of new dried foods with an acceptable shelf life from products widely consumed in the world with high nutritional content and health benefits, such as Dairy products. The present study aimed to determine the effect of temperature and product thickness during Refractance window drying in a laboratory scale dryer on the physicochemical properties of whole bovine milk and commercial flavored yogurt, using an optimal design model. The drying temperature range was between 40°C and 80°C, while the evaluated thickness ranged from 1 to 3 mm.

Molecular Profiling of Endocrine Resistance in HR+/HER2-Metastatic Breast Cancer: Insights from Extracellular Vesicles-Derived DNA and ctDNA in Liquid Biopsies.

Standard treatments in hormone receptor-positive (HR+)/HER2-metastatic breast cancer (mBC) typically involve endocrine therapy (ET) combined with CDK4/6 inhibitors, yet resistance to ET remains a persistent challenge in advanced cases. A deeper knowledge of the use of liquid biopsy is crucial for the implementation of precision medicine in mBC with real-time treatment guidance. Our study assesses the prognostic value of and mutations in DNA derived from extracellular vesicles (EV-DNA) in longitudinal plasma from 59 HR+/HER2-mBC patients previously exposed to aromatase inhibitors, with a comparative analysis against circulating tumor DNA (ctDNA).
