Time-frequency analysis combining wavelets and the envelope technique for fault identification in rotary machines
(2013-03-18)
Nowadays the method based on demodulation by envelope finds wide application in industry as a technique for evaluation of bearings and other components in rotating machinery. In recent years the application of Wavelets for ...
Signal detection in high dimension: the multispiked case
(Inst Mathematical Statistics, 2014-02)
This paper applies Le Cam's asymptotic theory of statistical experiments to the signal detection problem in high dimension. We consider the problem of testing the null hypothesis of sphericity of a high-dimensional covariance ...

Autographa californica M nucleopolyhedrovirus open reading frame 109 affects infectious budded virus production and nucleocapsid envelopment in the nucleus of cells
(Elsevier, 2013-01-20)
Autographa californica M nucleopolyhedrovirus (AcMNPV) open reading frame 109 (ac109) is conserved in all known baculovirus genomes, suggesting a crucial role in virus replication. Although viruses lacking ac109 have been ...
Use of gravitational waves to probe the formation channels of compact binaries
(Iop Publishing Ltd, 2017-02-09)
With the discovery of the binary black hole coalescences GW150914 and GW151226, the era of gravitational-wave astrophysics has started. Gravitational-wave signals emitted by compact binary coalescences will be detected in ...
Comparative proteomic analysis of Xanthomonas citri ssp citri periplasmic proteins reveals changes in cellular envelope metabolism during in vitro pathogenicity induction
(Wiley-Blackwell, 2018-01-01)
Citrus canker is a plant disease caused by Gram-negative bacteria from the genus Xanthomonas. The most virulent species is Xanthomonas citri ssp. citri (XAC), which attacks a wide range of citrus hosts. Differential proteomic ...
The dense molecular envelope around the compact H II region G5.89 - 0.39 (W28 A2)
(The American Astronomical Society, 1991-08-20)
VLA observations of ammonia in the (J, K) = (2, 2) and (3, 3) inversion transitions toward the compact H II region G5.89 - 0.39 are presented. These observations reveal the presence of a massive and hot molecular envelope ...
