Dynamics of Earth's Hadley Circulation [PDF]

open access: yes, 2013
This thesis advances our understanding of the mechanisms controlling the Hadley circulation, and its interaction with eddies on planetary scales in particular. On Earth, and more generally in a rapidly rotating and differentially heated planet, planetary

Multi-Approach Investigation Regarding the West Nile Virus Situation in Hungary, 2018

open access: yesViruses, 2020
The West Nile virus is endemic in multiple European countries and responsible for several epidemics throughout the European region. Its evolution into local or even widespread epidemics is driven by multiple factors from genetic diversification of the ...

West Nile Virus and Usutu Virus Co-Circulation in Europe: Epidemiology and Implications

open access: yesMicroorganisms, 2019
West Nile virus (WNV) and Usutu virus (USUV) are neurotropic mosquito-borne flaviviruses that may infect humans. Although WNV is much more widespread and plays a much larger role in human health, the two viruses are characterized by similar envelope ...

The location of diapycnal mixing and the meridional overturning circulation [PDF]

open access: yes, 2002
The large-scale consequences of diapycnal mixing location are explored using an idealized threedimensional model of buoyancy-forced flow in a single hemisphere. Diapycnal mixing is most effective in supporting a strong meridional overturning circulation (

Co-circulating microorganisms in questing Ixodes scapularis nymphs in Maryland [PDF]

open access: yesJournal of Vector Ecology, 2007
Ixodes scapularis can be infected with Borrelia burgdorferi, Anaplasma phagocytophilum, Bartonella spp., Babesia microti, and Rickettsia spp., including spotted-fever group Rickettsia. As all of these microorganisms have been reported in Maryland, the potential for these ticks to have concurrent infections exists in this region. To assess the frequency

Co-circulation of multiple genotypes of ARV in poultry in Anhui, China

open access: yesAvian Pathology, 2023
Poultry production in China has been experiencing a high incidence of broiler arthritis /tenosynovitis caused by avian orthoreovirus (ARV) since 2013. In the spring of 2020 severe arthritis cases from broiler flocks were identified in a large-scale commercial poultry company in Anhui Province, China.

Does Avian Coronavirus Co-Circulate with Avian Paramyxovirus and Avian Influenza Virus in Wild Ducks in Siberia?

open access: yesViruses, 2023
Avian coronaviruses (ACoV) have been shown to be highly prevalent in wild bird populations. More work on avian coronavirus detection and diversity estimation is needed for the breeding territories of migrating birds, where the high diversity and high ...

Co-circulation and persistence of multiple A/H3N2 influenza variants in China [PDF]

open access: yesEmerging Microbes & Infections, 2019
The spread of influenza A/H3N2 variants possessing the hemagglutinin 121 K mutation and the unexpectedly high incidence of influenza in the 2017-2018 northern hemisphere influenza season have raised serious concerns about the next pandemic. We summarized the national surveillance data of seasonal influenza in China and identified marked differences in ...

Residual circulation trajectories and transit times into the extratropical lowermost stratosphere [PDF]

open access: yes, 2010
Transport into the extratropical lowermost stratosphere (LMS) can be divided into a slow part (time-scale of several months to years) associated with the global-scale stratospheric residual circulation and a fast part (time-scale of days to a few months)

Evaluation of co-circulating pathogens and microbiome from COVID-19 infections [PDF]

open access: yesPLOS ONE, 2022
Co-infections or secondary infections with SARS-CoV-2 have the potential to affect disease severity and morbidity. Additionally, the potential influence of the nasal microbiome on COVID-19 illness is not well understood. In this study, we analyzed 203 residual samples, originally submitted for SARS-CoV-2 testing, for the presence of viral, bacterial ...
