A theory is proposed that combines the most basic features of conformal solution theory and scaled particle theory (SPT) . The treatment in essence provides a means for evaluating mixture properties from pure fluid data; however, two intermediate substances-the “infinitely polydisperse” (IP) mixture and the “one-and-a-half fluid”-are used to implement the mapping. Associated with the IP mixture...

Short-range entangled topological phases of matter are closely connected to Topological Quantum Field Theory. We use this connection to classify Symmetry Protected Topological Phases in low dimensions, including the case when the symmetry involves time-reversal. To accomplish this, we generalize Turaev’s description of equivariant TQFT to the unoriented case. We show that invertible unoriented ...

We study the problem of detecting, and infering astrophysical information from, gravitational waves from a pulsating neutron star. We show that the fluid f and p-modes, as well as the gravitational-wave w-modes may be detectable from sources in our own galaxy, and investigate how accurately the frequencies and damping rates of these modes can be infered from a noisy gravitational-wave data stre...

The Jean Delay Prize is the most important award of the WPA and is awarded to any individual who has made a major contribution to the integration of biological, psychological, and social aspects of psychiatry. The 2005 prize will be awarded at the opening ceremony of the next WPA World Congress in Cairo. The nomination form can be downloaded from the WPA website (http//www.wpanet.org or http//w...

Both GONG and MDI projects have measured p-mode frequencies of the Sun for more than 7 years. Here we review what we have learnt from the temporal variation of the oscillation frequencies and splitting coefficients.

Wireless networks are today an entire part of the Internet, and are often used by companies and particularies. Security of information is thus important, and protocols like WEP and WPA can be attacked. We present in this report the existent WLANs protocols, an overview of the most e cient attacks on them and two attacks we have found on WEP.

We employ tomographic observations of a small region of plage to study the propagation of waves from the solar photosphere to the chromosphere using a Fourier phase-difference analysis. Our results show the expected vertical propagation for waves with periods of 3 minutes. Waves with 5-minute periods, i.e., above the acoustic cut-off period, are found to propagate only at the periphery of the p...

Nonadiabatic effects associated with the transfer of energy and with turbulent stresses add small imaginary parts, wji> and w~2>, to solar p-mode eigenfrequencies. Numerical calculations have shown that these quite different processes make comparable contributions to W; at frequencies well below the acoustic cutoff at wac· We derive analytic expressions which reveal the connection between w~ 1 ...

The solar acoustic p-mode line profiles are asymmetric. Velocity spectra have more power on the low-frequency sides, whereas intensity profiles show the opposite sense of asymmetry. Numerical simulations of the upper convection zone have resonant p-modes with the same asymmetries and asymmetry reversal as the observed modes. The temperature and velocity power spectra at optical depth τ cont = 1...
