(Abridged) The WMAP 5-year data strongly limit deviations from the minimal LCDM model. We constrain physics of inflation via Gaussianity, adiabaticity, power spectrum shape, gravitational waves, and spatial curvature. also properties dark energy, parity-violation, neutrinos. detect no convincing parameters model, derived combined with distance measurements Type Ia supernovae (SN) Baryon Acoustic Oscillations (BAO), are: Omega_b=0.0456+-0.0015, Omega_c=0.228+-0.013, Omega_Lambda=0.726+-0.015,...
We present full sky microwave maps in five bands (23 to 94 GHz) from the WMAP first year survey. Calibration errors are <0.5% and low systematic error level is well specified. The 21 per mode l=658. temperature-polarization cross-power spectrum reveals both acoustic features a large angle correlation reionization. optical depth of reionization 0.17 +/- 0.04, which implies epoch 180+220-80 Myr (95% CL) after Big Bang at redshift 20+10-9 for range ionization scenarios.

We present cosmological parameter constraints based on the final nine-year Wilkinson Microwave Anisotropy Probe (WMAP) data, in conjunction with a number of additional data sets. The WMAP alone, and combination, continue to be remarkably well fit by six-parameter ΛCDM model.

The Wilkinson Microwave Anisotropy Probe WMAP has mapped the entire sky in five frequency bands between 23 and 94 GHz with polarization sensitive radiometers. We present three-year full-sky maps of analyze them for foreground emission cosmological implications. These observations open up a new window understanding universe. observes significant levels polarized due to both Galactic synchrotron radiation thermal dust emission. least contaminated channel is at 61 GHz. Informed by model...
We present the final nine-year maps and basic results from WMAP mission. provide new full sky temperature that were processed to reduce asymmetry of effective beams. Temperature polarization are examined separate CMB anisotropy foreground emission, both types signals analyzed in detail. The mission has resulted a highly constrained LCDM cosmological model with precise accurate parameters agreement host other measurements. When data combined finer scale CMB, baryon acoustic oscillation,...
This paper focuses on cosmological constraints derived from analysis of WMAP data alone. A simple ΛCDM model fits the five-year temperature and polarization data. The basic parameters are consistent with three-year now better constrained: Ωbh2 = 0.02273 ± 0.00062, Ωch2 0.1099 0.0062, ΩΛ 0.742 0.030, ns 0.963+0.014−0.015, τ 0.087 0.017, σ8 0.796 0.036, h 0.719+0.026−0.027. With five years data, we have measured optical depth to reionization, τ>0, at 5σ significance. redshift an instantaneous...
We present new full-sky temperature and polarization maps in five frequency bands from 23 to 94 GHz, based on data the first years of Wilkinson Microwave Anisotropy Probe (WMAP) sky survey. The are consistent with previous more sensitive. five-year incorporate several improvements processing made possible by additional a complete analysis instrument calibration in-flight beam response. tests for systematic errors conclude that W-band is not yet suitable cosmological studies, but we suggest...
The WMAP mission has produced sky maps from seven years of observations at L2. We present the angular power spectra derived seven-year and discuss cosmological conclusions that can be inferred data alone. With data, temperature (TT) spectrum measurement a signal-to-noise ratio per multipole exceeds unity for l < 919; in band powers width Δl = 10, up to 1060. third acoustic peak TT is now well measured by WMAP. In context flat ΛCDM model, this improvement allows us place tighter constraints...

The new results consistent with previous results, but have improved due to reduced noise the additional integration time, knowledge instrument performance, analysis procedures. improvements described in detail. seven-year set is well fit by a minimal six-parameter flat ΛCDM model. parameters for this model, using conjunction baryon acoustic oscillation Sloan Digital Sky Survey priors H0...
The WMAP mission has mapped the full sky to determine geometry, content, and evolution of universe. Full-sky maps are made in five microwave frequency bands separate temperature anisotropy cosmic background (CMB) from foreground emission, including diffuse Galactic emission extragalactic point sources. We define masks that excise regions high so CMB analyses can be carried out with minimal contamination. also present spectra individual components, leading an improved understanding...
We present new full-sky temperature maps in five frequency bands from 23 to 94 GHz, based on the first three years of WMAP sky survey. The maps, which are consistent with first-year and more sensitive, incorporate improvements data processing made possible by additional a complete analysis polarization signal. These include refinements gain calibration beam response models. employ two forms multi-frequency separate astrophysical foreground signals CMB, each improves our analyses. First, we...
We present the angular power spectrum derived from first-year Wilkinson Microwave Anisotropy Probe (WMAP) sky maps. study a variety of estimation methods and data combinations demonstrate that results are robust. The modestly contaminated by diffuse Galactic foreground emission, but we show simple template model is sufficient to remove signal. Point sources produce modest contamination in low frequency data. After masking ~700 known bright maps, estimate residual contribute ~3500 uK^2 at 41...
Summary In continuation of a previous paper (Bishop and Hill 1951) it is conjectured that the work done in plastically deforming polycrystal approximately equal to which would be if grains were free deform equally. conjunction with principle maximum plastic work, this enables yield function an aggregate calculated. This for isotropic face-centred cubic crystals, following determination stresses needed produce multi-slip. The theoretical criterion lies between those Tresca von Mises, good...
To find inherited causes of autism-spectrum disorders, we studied families in which parents share ancestors, enhancing the role factors. We mapped several loci, some containing large, inherited, homozygous deletions that are likely mutations. The largest implicated genes, including PCDH10 (protocadherin 10) and DIA1 (deleted autism1, or c3orf58), whose level expression changes response to neuronal activity, a marker genes involved synaptic underlie learning. A subset NHE9 (Na+/H+ exchanger...
Abstract The plasticity of metal polycrystals with preferred orientations is considered from a phenomenological standpoint. Some new general theorems are proved, in particular the existence work-equivalent function tensor strain-rate over any yield surface. status classical theory plastic anisotropy re-appraised light recent experiments, which themselves critically reviewed. A type proposed to account for so-called anomalous behaviour some materials.
(Abridged) A simple six-parameter LCDM model provides a successful fit to WMAP data, both when the data are analyzed alone and in combination with other cosmological data. Even so, it is appropriate search for any hints of deviations from now standard cosmology, which includes inflation, dark energy, matter, baryons, neutrinos. The community has subjected extensive varied analyses. While there widespread agreement as overall success model, various "anomalies" have been reported relative that...
We present updated estimates of Galactic foreground emission using seven years WMAP data. Using the power spectrum differences between multi-frequency template-cleaned maps, we find no evidence for contamination outside (KQ85y7) mask. place a 15 μK upper bound on rms in cleaned maps used cosmological analysis. Further, cleaning process requires only three power-law foregrounds polarized beyond those from soft (steep-spectrum) synchrotron and thermal dust emission; particular indication...
Brinell tests have long been the preferred method of assaying hardness metals during forming operations. The general significance test has codified in empirical laws, especially those Meyer, O’Neill and Tabor. On other hand, indentation elastoplastic media by a ball never thoroughly analysed context modern mechanics continua; this is objective here. actual boundary-value problem non-steady but can be made steady terms reduced variables when material response suitably modelled. Namely, strain...
Although there is increasing recognition of the role somatic mutations in genetic disorders, prevalence neurodevelopmental disease and optimal techniques to detect mosaicism have not been systematically evaluated.Using a customized panel known candidate genes associated with brain malformations, we applied targeted high-coverage sequencing (depth, ≥200×) leukocyte-derived DNA samples from 158 persons including double-cortex syndrome (subcortical band heterotopia, 30 persons), polymicrogyria...
We present the temperature and polarization angular power spectra of cosmic microwave background derived from first five years Wilkinson Microwave Anisotropy Probe data. The five-year spectrum is variance limited up to multipole ℓ = 530, individual ℓ-modes have signal-to-noise ratio S/N >1 for < 920. best-fitting six-parameter ΛCDM model has a reduced χ2 33–1000 χ2/ν 1.06, with probability exceed 9.3%. There now significantly improved data near third peak which leads cosmological...
Possible restrictions on isotropic constitutive laws for finitely deformed elastic solids are examined from the standpoint of Hill (1968). This introduced notion conjugate pairs stress and strain measures, whereby families contending inequalities can be generated. A typical member inequality stipulates that scalar product rates change certain variables is positive in all circumstances. Interrelations between various explored, some statical implications established. The discussion depends...
