Pathogenic potential of ornithogenic <i>Escherichia coli</i> strains detected in the Earth's polar regions by Batyrbek I. Aslanov, Daniil V. Azarov, Maria A. Makarova, Elizaveta G. Marysheva, Lyudmila A. Kraeva, Aleksey S. Mokhov, Ekaterina A. Lebedeva, Nikita E. Goncharov, Natalya V. Lebedeva, Dmitry A. Starikov, Victoria V. Kolodzhieva, Dmitry E. Polev, Artemy E. Goncharov

“…At the same time, the phylogeography of E. coli in relation to the presence of natural foci of colibacillosis in polar regions remains virtually unstudied. The aim of this study was to assess the pathogenic potential of E. coli strains from the polar regions of the Earth, based on the analysis of the genomes of these bacteria from typical ornithogenic ecosystems of the Arctic and Antarctic. …”

Design of CubeSat-Based Multi-Regional Positioning Navigation and Timing System in Low Earth Orbit by Georgios Tzanoulinos, Nori Ait-Mohammed, Vaios Lappas

“…The importance of Low Earth Orbit (LEO) PNT systems lies in their ability to enhance the GNSS by implementing signals in additional frequency bands, offering increased signal strength, reduced latency, and improved accuracy and coverage, particularly in challenging environments such as urban canyons or polar regions, thereby addressing the limitations of the traditional Medium Earth Orbit (MEO) GNSS. …”

Analyzing the observational capabilities of a Moon-based platform for monitoring Earth’s outgoing radiation by Guang Liu, Runbo Dong, Yin Jin, Mengxiong Zhou, Hanlin Ye, Rui Song, Jan-Peter Muller, Huadong Guo

“…The results show that: 1) the lowest daily ground coverage rate is about 88.8% and global coverage including polar regions can always be achieved within a month; 2) the sampling interval needs to be less than 4 hours to ensure the accuracy of reconstruction; 3) the image captured by a multi-spectral camera is capable of reconstructing the distribution of the Earth’s outgoing radiation, while the data obtained from a radiometer facilitates the reconstruction of the global Earth’s outgoing radiation, thereby enabling a comprehensive assessment of the Earth’s outgoing radiation. …”

Latitudinal Dependence of Cosmic Rays Modulation at 1 AU and Interplanetary Magnetic Field Polar Correction by P. Bobik, G. Boella, M. J. Boschini, C. Consolandi, S. Della Torre, M. Gervasi, D. Grandi, K. Kudela, S. Pensotti, P. G. Rancoita, D. Rozza, M. Tacconi

“…Since the whole transport is strongly related to the interplanetary magnetic field (IMF) structure, a better understanding of his description is needed in order to reproduce the cosmic rays intensity at the Earth, as well as outside the ecliptic plane. In this work an interplanetary magnetic field model including the standard description on ecliptic region and a polar correction is presented. …”
