Can ChatGPT support clinical coding using the ICD-10-CM/PCS?
Teixeira, B. N.; Leitão, A.; Nascimento, G.; Campos-Fernandes, A.; Cercas, F.Introduction: With the growing development and adoption of artificial intelligence in healthcare and across other sectors of society, various user-friendly and engaging tools to support research have emerged, such as chatbots, notably ChatGPT. Objective: To investigate the performance of ChatGPT as an assistant to medical coders using the ICD-10-CM/PCS. Methodology: We conducted a prospective exploratory study ...
An optimized planning tool for microwave terrestrial and satellite link design
Ferreira, E.; Sebastião, P.; Cercas, F.; Costa, C. S.; Correia, A.Today, the internet is fundamental to social inclusion. There are many people that live in remote areas, and the only way to supply internet services is through the use of microwave terrestrial and satellite systems. Thus, it is important to have efficient tools to design and optimize these systems. In this paper, a tool with the objective to shorten the time spent in the design process of microwave terrestrial...
Increasing reliability on UAV fading scenarios
Viana, J.; Madeira, J.; Nidhi; Sebastião, P.; Cercas, F.; Mihovska, A.; Dinis, R.Unmanned aerial vehicles (UAVs) are the next technology to be incorporated into a telecommunications network to improve command and control on a large scale in both line-of-sight (LOS) and non-line-of-sight (NLOS) conditions. However, there is still room for improvement in terms of reliability. This paper investigates Constant Packet Combining (CPC) and Adaptive Packet Combining (APC) techniques applied to Unma...
Low-complexity channel codes for reliable molecular communication via diffusion
Sofia Figueiredo; Souto, N.; Cercas, F.It is envisioned that healthcare systems of the future will be revolutionized with the development and integration of body-centric networks into future generations of communication systems, giving rise to the so-called “Internet of Bio-nano things”. Molecular communications (MC) emerge as the most promising way of transmitting information for in-body communications. One of the biggest challenges is how to minim...

IoT-based systems for soil nutrients assessment in horticulture
Postolache, S.; Sebastião, P.; Viegas, V.; Postolache, O.; Cercas, F.Soil nutrients assessment has great importance in horticulture. Implementation of an information system for horticulture faces many challenges: (i) great spatial variability within farms (e.g., hilly topography); (ii) different soil properties (e.g., different water holding capacity, different content in sand, sit, clay, and soil organic matter, different pH, and different permeability) for different cultivated...

Two methods for jamming identification in UAV networks using new synthetic dataset
Viana, J.; Farkhari, H.; Campos, L. M.; Sebastião, P.; Cercas, F.; Bernardo, L.; Dinis, R.Unmanned aerial vehicle (UAV) systems are vulnerable to jamming from self-interested users who utilize radio devices to disrupt UAV transmissions. The vulnerability occurs due to the open nature of air-to-ground (A2G) wireless communication networks, which may enable network-wide attacks. This paper presents two strategies to identify Jammers in UAV networks. The first strategy is based on a time series approac...
