In this abstract, we present a beamforming method for estimating the directions and locations of multiple sources and separating each source’s spectrum from field data collected by a wireless acoustic sensor network. Each acoustic sensor is equipped with four microphones that receive acoustic signals in a timesynchronized manner. The difference in time-of-arrival of proximal signals depends on ...

the lernaea parasite was reported in alburnus hohenackeri kessler, 1870, collected from the char-nimeh (or chahnimeh) lake, eastern iran. three fishes were infected with l. intestinalis having 3 to 22 parasites increasing with fish size. the maximum and minimum of parasite lengths were 138.02 mm and 24.54 mm respectively. the prevalence, mean intensity and abundance of infection by plerocercoid...

GTI-2501 is a 20-mer oligonucleotide that is complementary to a coding region in the mRNA of R1, the large subunit of ribonucleotide reductase (RNR). In vitro studies, have demonstrated that GTI-2501 decreases mRNA and protein levels of R1 in a sequence-specific and dosedependent manner. Furthermore, GTI-2501 inhibits the growth of human lung, liver, ovary, brain, melanoma, breast and pancreati...

To evaluate the effects of the juvenile hormone analogue pyriproxyfen on colonies of the Pharaoh ant Monomorium pharaonis (L.), peanut oil containing different concentrations (0.3, 0.6, or 0.9%) of pyriproxyfen was fed to monogynous (1 queen, 500 workers, and 0.1 g of brood) and polygynous (8 queens, 50 workers, and 0.1 g of brood) laboratory colonies of M. pharaonis. Due to its delayed activit...

As we have entered the information age and developed a digital economy, with the rapid development of satellite communications, the universal penetration of the internet, and the emergence of intelligent industries, ‘speed’ and ‘innovation’ have become the main factors spurring industrial development. Taiwan, with its universal education, highly educated citizenry, high-quality workforce, and f...

Wie schwer ist es zu multiplizieren? Jeder hat in der Schule die Methode zum ” schriftlichen“ Multiplizieren – die sog. ” Schulmethode der Multiplikation“ – kennen gelernt. Unsere Schulkenntnisse reichen also aus, einen effizienten Algorithmus zum Multiplizieren von langen Zahlen anzugeben. Um zwei n-stellige Zahlen zu multiplizieren, benötigt man mit der Schulmethode Θ(n) Additionen und Multip...
