The text provides an analysis of various studies and applications of augmented reality (AR) and virtual reality (VR) in the educational context, with a focus on their use in Brazil and a comparative study of the technologies. It discusses the implementation of AR and VR in teaching the solar system, the development of a virtual planetarium, and the use of e-learning for teaching natural sciences. The text also reviews the advantages and disadvantages of AR and VR in education, citing works that emphasize the need for digital infrastructure and trained teachers, and the potential for technology addiction. The studies highlight the positive impact of these technologies on student motivation and understanding of material, despite some challenges with hardware limitations.

Red Sea Global (RSG) has conducted one of the world's largest environmental surveys along 125 miles of Saudi Arabia's northwestern coastline, aiming to deliver a net conservation benefit of 30 percent by 2040 through regenerative tourism projects. The survey, led by a team including Dr. Luis Silva, recorded diverse marine life, including endangered species, and utilized advanced technologies like Coral Net and Structure from Motion photogrammetry. The findings will help track the impact of marine protection efforts and contribute to global scientific knowledge.

The paper explores the control of chaos in one-dimensional dynamical systems through the use of flat-topped maps, known as simple limiter control. The study introduces limiters in the tent map according to a binary sequence iteration pattern, defining local and Milnor attractors in a non-autonomous context. The existence and coexistence of these attractors are examined in relation to the limiter value and the iteration pattern. Symbolic dynamics are utilized to characterize and describe the attractor families. The research finds that non-autonomous systems exhibit a variety of behaviors not possible in autonomous cases, including the potential coexistence of multiple attractors. The findings have implications for controlling chaos in various fields, such as cardiac dynamics, telecommunications, and market dynamics, with potential for reducing implementation costs.

5G technology is transforming Houston into a smart city, enhancing public safety and efficiency. Firefighters use drones, infrared tech, and live video for rescue operations, while paramedics share medical records in real-time and are guided by traffic signals for faster hospital transport. AT&T's 5G+ at Toyota Center and FirstNet for first responders are examples of this tech in action. 5G's capacity for Massive IoT and ultra-low latency is crucial for these advancements, potentially leading to autonomous cars, improved utility grids, and reduced traffic congestion.
