The design of new strategies that exploit methods from machine learning to facilitate the resolution of challenging and large-scale mathematical optimization problems has recently become an avenue of prolific and promising research. In this paper, we propose a novel learning procedure to assist in the solution of a well-known computationally difficult optimization problem in power systems: The Direct Current Optimal Transmission Switching (DC-OTS) problem. The DC-OTS problem consists in finding the configuration of the power network that results in the cheapest dispatch of the power generating units.

Article Synopsis
  • The study investigates how various factors like gas exchange rates and vessel sizes influence the growth of high-quality in vitro potato plants across different landraces.
  • Results showed that using plastic vessels with HEPA filters improved plant characteristics such as thicker stems and increased leaf area when compared to standard culture vessels.
  • Higher planting densities negatively impacted some growth metrics but increased plant height, and significant differences in nutrient ion uptake were observed among the potato genotypes.

Article Synopsis
  • * Although treatment with doxycycline and azithromycin has been effective so far, antibiotic resistance is a growing concern due to the widespread use of these medications.
  • * This study found 12 genes linked to antibiotic resistance in various species of the genus, signaling a need for further research to explore if these genes are active in different types of the bacteria.

This experimental study analyzes the seismic behavior of rammed earth walls with Arundo donax natural fiber inclusions, also called "caña brava" (REWC), and without inclusions (REW). The experimental program consists of two stages: physical and mechanical characterization of materials, where properties such as particle size, density, Atterberg limits, and compressive and flexural strength were determined; and dynamic tests, which included compressive and cyclic load tests on REW and REWC walls. The walls were subjected to cyclic loading with derivatives between 0.
