Singular spectrum analysis is developed as a nonparametric spectral decomposition of a time series. It can be easily extended to the decomposition of multidimensional lattice-like data through the filtering interpretation. In this viewpoint, the singular spectrum analysis can be understood as the adaptive and optimal generation of the filters and their two-step point-symmetric operation to the ...

A 45MHz-2.5GHz broadband CMOS up-conversion mixer implemented in a conventional 0.18µm technology is presented this letter. The offered employs bisymmetric class-AB input stage order to provide high linearity and match the IF impedance over 0.3-20.15MHz frequency range. draws 3mA current from 1.8V supply voltage, core chip dimension of 0.05*0.08mm2. At range 45MHz-2.5GHz, output third-order int...

Abstract. The reaction of serpentinized peridotite with CO2-bearing fluids to form listvenite (quartz–carbonate rock) requires massive fluid flux and significant permeability despite an increase in solid volume. Listvenite serpentinite samples from Hole BT1B the Oman Drilling Project help understand mechanisms feedbacks during vein formation this process. Samples analyzed study contain abundant...

S OF PAPERS SUBMITTED FOR PRESENTATION TO THE SOCIETY The following papers have been submitted to the Secretary and the Associate Secretaries of the Society for presentation at meetings of the Society. They are numbered serially throughout this volume. Cross references to them in the reports of the meetings will give the number of this volume, the number of this issue, and the serial number of ...

Giant radio galaxies are thought to be massive ellipticals powered by accretion of interstellar matter onto a supermassive black hole. Interactions with gas rich galaxies may provide the interstellar matter to feed the active galactic nucleus (AGN). To power radio lobes that extend up to distances of hundreds of kiloparsecs, gas has to be funneled from kiloparsec size scales down to the AGN at ...

We characterize the solutions of the equation D(G(x, y), G(u, v)) = G(D(x, u), T (y, v)) (1) where D, G and T are quasigroups. We also discuss the particular case when D = T .

The joint receipt of x and y is the fact of receiving them both. If x and y are objects that are valued, their joint receipt is valued as well. Assumming joint receipt is a binary operation that satisfies the conditions of extensive measurement, there is a numerical representation that is additive over joint receipt. We consider the case where x and y are quantities of the same infinitely divis...

We have performed a statistical analysis of a sample of 1100 extra-galactic rotation measures (RMs) obtained from the literature. Using a subsample of approximately 800 reliable RMs we compute a rotation measure sky and determine reliable large scale features for the line of sight Galactic magnetic field. We find that the influence of the Milky Way can be seen up to roughly 30◦ on either side o...

The large scale magnetic fields of our Galaxy have been mostly revealed by rotation measures (RM s) of pulsars and extragalactic radio sources. In the disk of our Galaxy, the average field strength over a few kpc scale is about 1.8 µG, while the total field, including the random fields on smaller scales, has a strength of about 5 µG. The local regular field, if it is part of the large scale fie...
