Semantic SLAM with Multi-Modal Perception: Survey on Robust Long-Term Localization for Autonomous Vehicles

Álvaro Navarro-Pérez · Bladimir Bacca-Cortés · Eduardo Caicedo-Bravo

Long-term localization in dynamic and changing environments remains a key challenge for autonomous vehicles. Semantic Simultaneous Localization and Mapping (SLAM) enhances traditional SLAM by integrating high-level semantic understanding, enabling robust mapping and localization even under complex scenarios. In this co...

Franck Morais de Oliveira · Verónica González Cadavid · Jairo Alexander Osorio Saraz · Felipe Andrés Obando Vega · y 2 más

Pig weighing is an essential procedure for monitoring growth and animal health; however, conventional methods are often labor-intensive, costly, and potentially stressful. In this context, this study proposes a non-invasive approach for estimating the body weight of pigs during the growing stage based on computer visio...

Validation of SpO2/FiO2 as a Non-Invasive Surrogate of PaO2/FiO2 in Mechanically Ventilated COVID-19 Patients at High Altitude

Guillermo Ortiz-Ruiz · Manuel Garay-Fernández · Eduardo Tuta-Quintero · Alirio Bastidas · y 5 más

Background: The ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (PaO2/FiO2) is central to the classification of acute respiratory distress syndrome (ARDS). However, its assessment requires arterial blood gas analysis, which may be limited by availability, cost, and invasiveness. Consequently...

Ontogenetic thresholds in larval development, azadirachtin susceptibility, and survival dynamics of Spodoptera frugiperda under high-mountain Andean conditions: an integrated framework for altitude-adapted IPM

Humberto Giraldo-Vanegas · Sanly Natalia Núñez-García · Selena Marily Velásquez-López · Mayda Yarely Reatiga-Pulido · y 2 más

Abstract Background: Spodoptera frugiperda (J.E. Smith, 1797) is a globally invasive pest whose developmental biology and responses to botanical insecticides have been characterized almost exclusively under lowland tropical conditions, leaving a critical knowledge gap for high-mountain Andean agroecosystems. This study...
