Molecular epidemiological study of enterovirus D68 in hospitalised children in Hong Kong in 2014–2015 and their complete coding sequences
Autor: Haichao Wang, Kinpong Tao, Cheuk Yin Leung, Kam Lun Hon, C M Apple Yeung, Zigui Chen, K S Paul Chan, Ting-Fan Leung, W Y Renee Chan
Publikováno v: BMJ Open Respiratory Research, Vol 6, Iss 1 (2019)
Background Human enterovirus D68 (EV-D68) was first isolated in 1962 and has aroused public concern recently because of a nationwide outbreak among children in 2014–2015 in the USA. The symptoms include fever, runny nose, sneezing, cough and muscle

Characteristics of equatorial ionization anomaly (EIA) in relation to transionospheric satellite links around the northern crest in the Indian longitude sector
Autor: A. Das, K. S. Paul, S. Halder, K. Basu, A. Paul
Publikováno v: Annales Geophysicae, Vol 32, Pp 91-97 (2014)
The poleward gradient of the equatorial ionization anomaly (EIA) introduces more intense propagation effects on transionospheric satellite links in comparison to the equatorward gradient. Characterization of the poleward gradient was performed dur

Investigation of Satellite Trace (ST) and Multi-reflected Echo (MRE) ionogram signatures and its possible correlation to nighttime spread F development from Cyprus over the solar mini-max (2009–2016)
Autor: K. S. Paul, Ashik Paul, Haris Haralambous, Christina Oikonomou
Publikováno v: Advances in Space Research. 67:1958-1967
Multi-reflected echoes (MREs) and satellite traces (STs) are referred in literature as ionogram signatures of Travelling Ionospheric Disturbances (TIDs) which is a phenomenon that apparently drives spread F development mainly at nighttime mid-latitud

Long-term aspects of nighttime spread F over a low mid-latitude European station
Autor: Haris Haralambous, K. S. Paul, Ashik Paul, Christina Oikonomou
Publikováno v: Advances in Space Research. 64:1199-1216
In an effort to explore the morphology of nighttime spread F at the lower mid-latitude European station of Nicosia, Cyprus (35°N, 33°E geographic; magnetic dip. 29.38°N), all ionograms recorded by the DPS-4D digisonde during the interval 2009–20

Assessment of GPS Multifrequency Signal Characteristics During Periods of Ionospheric Scintillations from an Anomaly Crest Location
Autor: K. S. Paul, Ashik Paul, Samiddha Goswami
Publikováno v: Radio Science. 52:1214-1222
Multi-frequency GPS transmissions have provided the opportunity for testing the applicability of the principle of frequency diversity for scintillation mitigation. Published results addressing this issue with quantified estimates are not available in

Relation of decorrelated transionospheric GPS signal fluctuations from two stations in the northern anomaly crest region with equatorial ionospheric dynamics
Autor: K. S. Paul, Ashik Paul
Publikováno v: Radio Science. 52:677-692
The ionosphere around the northern crest of the equatorial ionization anomaly (EIA) and beyond exhibits rapid temporal as well as spatial development of ionization density irregularities during postsunset hours. A GPS campaign was conducted during Se

Impact of multiconstellation satellite signal reception on performance of satellite-based navigation under adverse ionospheric conditions
Autor: K. S. Paul, Ashik Paul, A. Das
Publikováno v: Radio Science. 52:416-427
Application of multi-constellation satellites to address the issue of satellite signal outages during periods of equatorial ionospheric scintillations could prove to be an effective tool for maintaining the performance of satellite-based communicatio

Study of the effect of 17–18 March 2015 geomagnetic storm on the Indian longitudes using GPS and C/NOFS
Autor: B. Roy, Ashik Paul, Haris Haralambous, Christina Oikonomou, S. Ray, Samiddha Goswami, Babita Chandel, K. S. Paul
Publikováno v: Journal of Geophysical Research: Space Physics. 122:2551-2563
The largest geomagnetic storm in solar cycle 24 occurred during March 17-18, 2015 where the main phase of the storm commenced from 07:00 UT of March 17, 2015 and reached the Dst negative minimum at 22:00 UT. The present paper reports observations of
