AcrOSS platform: Advancing safe UAS operations in critical areas
2025-04-29
(Press-News.org)
In a recent development in the field of unmanned aircraft systems (UAS), a research team from the University of Salento in Italy has designed and tested a novel platform named AcrOSS. The details of this platform are published in Engineering, aiming to enhance the safety and efficiency of UAS operations in critical areas.
The widespread use of UAS in civil airspace, especially for beyond visual line-of-sight (BVLOS) operations, faces numerous challenges. The AcrOSS project, funded by the Italian Ministry for Research, focuses on developing a comprehensive UAS traffic management (UTM) platform. This platform is designed to manage access to low-altitude airspace, facilitate BVLOS operations, and ensure the safe integration of UAS into both controlled and uncontrolled airspace.
The AcrOSS platform features a three-layer architecture, including the air traffic management and control (ATM/ATC) layer, the UAS Service Supplier (USS) layer, and the UAS layer. Each layer has distinct responsibilities. For example, the ATM/ATC layer manages manned aircraft and relevant airspace, while the USS layer is in charge of UAS operations. Key components of the platform include a Notification/Authorization (N&A) platform, which coordinates airspace operations; an advanced UAS platform with an augmented reality (AR) component to improve pilots’ situation awareness; and a contingency manager that suggests actions in case of unexpected events.
During the experimental tests at the Grottaglie–Taranto airport in Italy, the platform’s functionality was thoroughly examined. The UAS chosen for testing was the DJI Mavic 2 Enterprise Dual quadcopter. The tests covered various aspects, such as flight parameter monitoring, geofence functionality, and the response to contingency scenarios. The results showed that the platform could accurately display flight parameters in real time, and the geofence effectively signaled potential violations.
Operators involved in the tests provided valuable feedback. They positively evaluated the detection system based on the Drone Box and the flight plan submission system of the N&A platform for its user-friendly interface. However, they also suggested several improvements. These include integrating weather forecast information into the flight plan submission process, extending the cartographic map, and enhancing the interface of the AR headset.
Although the AcrOSS platform represents a significant step forward in UAS traffic management, it has some limitations. The ergonomics of the AR headset, such as potential fatigue during long-term use and visibility issues in bright light, need to be addressed. Additionally, the integration between certain components could be optimized, and more comprehensive tests with a larger number of UAS pilots are required.
Looking ahead, the research team plans to test the platform in different critical scenarios and integrate weather forecast information obtained from public application program interface (APIs). This will further improve the platform’s performance and contribute to the safe and efficient operation of UAS in various environments.

A new study published in Engineering presents an innovative approach to building energy management that combines quantum computing with model predictive control (MPC), aiming to enhance energy efficiency and drive decarbonization in buildings.
Buildings are major energy consumers, contributing significantly to global energy use and greenhouse gas emissions. To address these issues, researchers Akshay Ajagekar and Fengqi You from Cornell University developed an adaptive quantum approximate optimization-based MPC strategy. This strategy is designed for buildings equipped with battery energy storage and renewable energy generation systems, such as photovoltaic (PV) panels.

PHOENIX, Ariz. — April 30, 2025 — HonorHealth Research Institute’s new downtown Phoenix laboratory has produced its first study, centered on a promising new treatment for pancreatic cancer, one of the most aggressive and difficult to treat of all malignancies.
Study results were presented April 29 in Chicago at the annual meeting of the 58,000-member American Association for Cancer Research (AACR), the world’s largest professional organization of cancer investigators, caregivers and patient advocates.
Study findings indicate that a newly discovered drug, RMC-6236, also known as Daraxonrasib, is a powerful inhibitor of RAS (including KRAS, NRAS and HRAS). These ...

SCOTTSDALE, Ariz. — April 29, 2025 — HonorHealth Research Institute recently treated the first patient in a 50-site international clinical trial that will test a new type of therapy aimed at difficult-to-treat melanoma, an aggressive type of skin cancer.
This new therapy targets PRAME, a peptide commonly found in melanoma tumors. The therapy uses the patient’s own manufactured and enhanced immune system T cells to create billions of new patient specific cells to attack melanoma, even after the cancer has spread to other parts of the body.
“We are excited about the potential of this new type of cellular therapy,” said Justin Moser, M.D., an associate ...

WASHINGTON, April 29, 2025 – The beloved Italian pasta cacio e pepe is perhaps best known for two things: being delicious and being frustratingly difficult to cook. At first glance, it looks like a simple recipe, containing only three ingredients: pasta, pecorino romano cheese, and black pepper. But as anyone who has tried to make it will know, the cheese will often clump when added to the hot pasta water, turning what is supposed to be a smooth, creamy sauce into a stringy, sticky mess.

About The Study: Semaglutide and tirzepatide prescriptions within Epic-affiliated health care systems increased slightly between 2021 and 2024, but their uptake remained limited, with only 3% of eligible patients having ever received a prescription during that period. Furthermore, there were disparities in prescribing of varying magnitude based on race and ethnicity, social vulnerability, and urbanicity, although the absolute differences were small compared with the overall underutilization.
