West Nile virus (WNV) was first detected in North America in 1999 during an outbreak of encephalitis in New York City. Since then the virus has spread across North America and into Canada, Latin America, and the Caribbean. The largest epidemics of neuroinvasive WNV disease ever reported occurred in the United States in 2002 and 2003. This paper reviews new information on the epidemiology and cl...
In this paper, a reduced-rank scheme with joint iterative optimization is presented for direction of arrival estimation. A rank-reduction matrix and an auxiliary reduced-rank parameter vector are jointly optimized to calculate the output power with respect to each scanning angle. Subspace algorithms to estimate the rank-reduction matrix and the auxiliary vector are proposed. Simulations are per...
We consider the direction finding problem in time-varying arrays composed of identically oriented subarrays displaced by unknown vector translations. A new eigenstructure-based estimator is proposed for such a class of partly calibrated sensor arrays.
Introduction: The present study aimed to investigate the change of air pollutants in 2020 in Qom compared to the same period in 2019 in five scenarios. Materials and Methods: The hourly air quality data was obtained from air quality monitoring stations of Qom Environmental Protection Organization (EPO). The meteorological parameters were obtained from Iranian Meteorological Organization websi...
BHR (Badan Hisab Rukyat) North Sumatra Province revealed that it is oftentimes for qibla direction of mosques in Medan City which does not face the Ka’bah or Masjidil Haram, but to west and South Africa. This attracted author's attention examine City, especially As Salam Mosque Sunggal. research aims find out how measure Qibla using Kompas Kiblat RHI instrument so known as azimuth uses a qualit...
Introduction & Objectives: A laboratory study was carried out to investigate the insecticidal, irritant and anti-feeding effects of nets treated with various pyrethroids against susceptible and highly pyrethroid resistant strains of An. stephensi. Materials & Methods: Tests were carried out inside a mosquito cage measuring 25×25×25 cm where mosquitoes were offered the opportunity to feed blo...
The present paper discuss on spatial and temporal distribution of chlorophyll-a (Chl-a) in the coastal and offshore waters of northeastern Arabian Sea, using Advanced Earth Observation Satellite OCTS data. The Chla concentration found high all along the western Indian coastal waters, with significant variations at Gulf of Cambay and Gulf of Kutch regions, ranging from 0.05 to 4.0 mg m. Several ...
To determine the cause of an unprecedented outbreak of encephalitis among horses in New South Wales, Australia, in 2011, we performed genomic sequencing of viruses isolated from affected horses and mosquitoes. Results showed that most of the cases were caused by a variant West Nile virus (WNV) strain, WNV(NSW2011), that is most closely related to WNV Kunjin (WNV(KUN)), the indigenous WNV strain...
A serosurvey for neutralizing antibodies against West Nile virus (WNV) in common coots (Fulica atra) was conducted in Doñana, Spain. Antibody prevalence was highest in 2003, intermediate in 2004, and lowest in 2005. Some birds seroreverted <1 year after first capture. Seroconversion of birds suggests local circulation of the virus.
