Heterogeneous aquatic robot systems, consisting of ROVs, AUVs, ASVs, and UAVs, are vital for environmental exploration, monitoring, and task execution. This paper presents advancements in critical technologies within these systems, focusing on communication (underwater acoustic, radio, and optical), multi-sensor fusion, and collaborative navigation techniques. It reviews control strategies like deep reinforcement learning, end-to-end control, and large model-based methods, addressing autonomous decision-making and adaptability in complex environments. The paper also discusses energy management strategies for efficient storage, utilization, and recovery. Furthermore, it explores the ethical and environmental impacts of deploying such systems, emphasizing sustainability and minimizing ecological disruptions. Finally, case studies and applications in ocean exploration and environmental monitoring are highlighted, showcasing the real-world utility and future potential of heterogeneous aquatic robot systems. This work provides valuable insights into the technological, ethical, and practical considerations for developing these systems.

Background Migraine is a common disorder in general population. Presence of white matter hyperintensities (WMHs) in brain MRI of migraine patients was not studied clearly. Detection of the prevalence of white matter hyperintensities in migraine patients determines its correlation with migraine severity, type and duration. Methods Cross sectional analytic study was conducted on migraine patients attending neurology clinic Suez Canal University Hospital. Sixty-five patients with migraine aged from 18 to 50 years were included. We excluded smokers and patients with hypertension, cardiac disease, diabetes mellitus, endocrine dysfunction, oncological and hematological diseases, infectious diseases, demyelinating disorders, and Alzheimer disease. Brain MRI and laboratory investigation was done for all patients. Results White matter hyperintensities were significant more frequent in migraine with aura than those without aura. According to MIGSEV scale, white matter hyperintensities were highly significantly more frequent in grade III severity than grades II and I. The number of white matter hyperintensities increases significantly with increase intensity of pain during attack. The number of white matter hyperintensities increases significantly with increase intensity of nausea, disability, tolerability during attack and age. Resistance to treatment also shows statistically significant difference in increase number of WMHs. Conclusions White matter hyperintensities are present in 43.1% of migraine patients. Age, presence of aura, nausea, disability during attack, resistance to treatment, and severity of headache and duration of migraine are considered a risk factor for development of white matter hyperintensities.
