We present the implementation of a novel economic model predictive control (E-MPC) strategy for froth flotation, the largest tonnage mineral separation process. A previously calibrated and validated dynamic model incorporating froth physics was used,

We analyze a bright and rare burst, GRB20221009A, showing through NED data that the angular distance between GRB221009A and the supernova SN 2022xiw is almost the same angular separation with galactic objects, i.e., the SN-GRB connection at z = 0.151

This work describes the development and validation of a digital twin for a semi-autogenous grinding (SAG) mill controlled by an expert system. The digital twin consists of three modules emulating a closed-loop system: fuzzy logic for the expert contr

Brugada syndrome (BrS) is a non-structural cardiac disease that affects cardiac ion channels; it is characterized by clinical manifestations such as arrhythmias, tachycardia, syncope and sudden death, among others. Its diagnosis is mainly electrocard

The introduction of nonlinearities in the Schr\"odinger equation has been considered in the literature as an effective manner to describe the action of external environments or mean fields. Here, in particular, we explore the nonlinear effects induce

We show evidence of particle acceleration at GEV energies associated directly with protons from the prompt emission of a long-duration M6-class solar flare on July 17, 2023, rather than from protons acceleration by shocks from its associated Coronal

Abstract Background Negative dysphotopsias (ND) are visual aberrations associated with in-the-bag optic intraocular lens (IOL) placement, causing arc-shaped or linear shadows. Reverse optic capture (ROC) is employed to prevent ND, yet it poses the ri

Abstract Microglia-driven neuroinflammation plays an important role in the development of Alzheimer’s disease. Microglia activation is accompanied by the formation and chronic expression of TLR4 inflammarafts, defined as enlarged and cholesterol-ri

Although most superior vena cava (SVC) syndromes are due to intrathoracic malignancies, some are iatrogenic, such as those following the intravenous implantation of pacemaker wires. To date, the occurrence of this syndrome after epicardial pacemaker

We look for a diurnal anisotropy in the cosmic ray flow, using the Mexico-City Neutron Monitor (NM) detector, due to the Earth's orbital motion and predicted by Compton-Getting (C-G) in 1935, as a first-order relativistic effect. The Mexico-City NM's
