Russian Universities as Actors of Arctic Science Diplomacy
Abstract. This article examines the role of Russian universities in emerging and further developing Arctic science diplomacy (ASD). According to authors, in the current geopolitical conditions Russian universities are significant ASD actors which perform a number of important functions for the organization of international scientific cooperation with foreign countries and making a positive image of Russia in the world. The paper uses a systemic approach to identify Russian universities’ contribution to the ASD development through various mechanisms: joint research projects and publications with foreign partners, the organization of international events on the Arctic issues and participation in prestigious international conferences on the Arctic research area, joint polar expeditions (land and maritime), and participation of Russian scientists in international Arctic scientific organizations, etc. The university ASD is exemplified by the Russian leading universities – St. Petersburg State University, Moscow State University, Northern (Arctic) Federal University, etc. The study demonstrated that maintaining a dialogue on an ongoing basis within the framework of research and educational activities of universities can contribute to the systematic establishment of cooperation in other areas of international relations, the search for innovative solutions for the benefit of the development of the entire Arctic region

Automated melanoma diagnosis system
An automated melanoma diagnosis system, the so-called Skin Polar-probe, was developed to improve the chances of early detection of skin cancers and help save the lives of melanoma victims. The system will offer unique benefits to aid early detection of melanoma - the key to reducing deaths caused by this cancer
The performance of solarscan : an automated dermoscopy image analysis instrument for the diagnosis of primary melanoma
Objective To describe the diagnostic performance of SolarScan (Polartechnics Ltd, Sydney, Australia), an automated instrument for the diagnosis of primary melanoma.Design Images from a data set of 2430 lesions (382 were melanomas; median Breslow thickness, 0.36 mm) were divided into a training set and an independent test set at a ratio of approximately 2:1. A diagnostic algorithm (absolute diagnosis of melanoma vs benign lesion and estimated probability of melanoma) was developed and its performance described on the test set. High-quality clinical and dermoscopy images with a detailed patient history for 78 lesions (13 of which were melanomas) from the test set were given to various clinicians to compare their diagnostic accuracy with that of SolarScan.Setting Seven specialist referral centers and 2 general practice skin cancer clinics from 3 continents. Comparison between clinician diagnosis and SolarScan diagnosis was by 3 dermoscopy experts, 4 dermatologists, 3 trainee dermatologists, and 3 general practitioners.Patients Images of the melanocytic lesions were obtained from patients who required either excision or digital monitoring to exclude malignancy.Main Outcome Measures Sensitivity, specificity, the area under the receiver operator characteristic curve, median probability for the diagnosis of melanoma, a direct comparison of SolarScan with diagnoses performed by humans, and interinstrument and intrainstrument reproducibility.Results The melanocytic-only diagnostic model was highly reproducible in the test set and gave a sensitivity of 91% (95% confidence interval [CI], 86%-96%) and specificity of 68% (95% CI, 64%-72%) for melanoma. SolarScan had comparable or superior sensitivity and specificity (85% vs 65%) compared with those of experts (90% vs 59%), dermatologists (81% vs 60%), trainees (85% vs 36%; P =.06), and general practitioners (62% vs 63%). The intraclass correlation coefficient of intrainstrument repeatability was 0.86 (95% CI, 0.83-0.88), indicating an excellent repeatability. There was no significant interinstrument variation (P = .80).Conclusions SolarScan is a robust diagnostic instrument for pigmented or partially pigmented melanocytic lesions of the skin. Preliminary data suggest that its performance is comparable or superior to that of a range of clinician groups. However, these findings should be confirmed in a formal clinical trial.<br /
