The Thermal Sunyaev Zel’dovich effect: a powerful probe for missing baryons
, 2001
"... Abstract. About 90 % of baryons in the universe have thus far escaped direct observation. This is known as the missing baryon problem. The Sunyaev Zel’dovich effect (SZ effect) has the potential to directly measure the state of the majority of these missing baryons. The next generation CMB experimen ..."

experiments such as AMIBA will provide an unbiased sample of the intergalactic medium through the SZ effect. The existing and upcoming simulations and analytical studies provide a quantitative understanding of the SZ effect. All these make the SZ effect a powerful baryon probe. We present an overview
First year Wilkinson Microwave Anisotropy Probe (WMAP) observations: implications for inflation. Astrophys
 J. Suppl
"... We describe our methodology for comparing the WMAP measurements of the cosmic microwave background (CMB) and other complementary data sets to theoretical models. The unprecedented quality of the WMAP data, and the tight constraints on cosmological parameters that are derived, require a rigorous anal ..."

with the Lyman α forest. These last two data sets complement the CMB measurements by probing the matter power spectrum of the nearby universe. Combining CMB and 2dFGRS requires
published research findings are false.
, 2005
"... Summary There is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relation ..."

RADIAL ARC STATISTICS: A NEW POWERFUL PROBE OF THE CENTRAL DENSITY PROFILE OF GALAXY CLUSTERS
, 2000
"... We show that an expected number ratio of radial arcs (gravitationally lensed images whose major axes lie in the radial direction of a clusterlens potential) to tangential arcs (gravitationally lensed images whose major axes lie in the tangential direction) has strong dependence on the central densi ..."

We show that an expected number ratio of radial arcs (gravitationally lensed images whose major axes lie in the radial direction of a clusterlens potential) to tangential arcs (gravitationally lensed images whose major axes lie in the tangential direction) has strong dependence on the central density profile of galaxy clusters and has little dependence on other parameters, e.g. cluster temperature, background source galaxy redshift etc.. A comparison of the expected number ratios with observed ratios provides a robust test to constrain the central density profile of galaxy clusters. A tentative comparison with the observational data shows that the central density profile of galaxy clusters is ρ(r) ∝ r−1∼−1.5. This result indicates that the dark matter is collisionless at least on cluster scale. Our result gives an upper limit on a collision crosssection of selfinteraction of dark matter (σcoll) as σcoll/m < 0.1 cm 2 /g where m is a dark matter particle mass. Subject headings: galaxies: clusters: general — dark matter — gravitational lensing 1.

"... An adaptive (n, m, s, t)scheme is a deterministic scheme for encoding a vector X of m bits with at most n ones by a vector Y of s bits, so that any bit of X can be determined by t adaptive probes to Y. A nonadaptive (n, m, s, t)scheme is defined analogously. The study of such schemes arises in th ..."

Load balancing and the power of preventive probing
"... Consider a randomized load balancing problem consisting of a large number n of server sites each equipped with K servers. Under the greedy policy, clients randomly probe a site to check whether there is still a server available. If not, d − 1 other sites are probed and the task is assigned to the si ..."
