We measure cosmological parameters using the three-dimensional power spectrum $P(k)$ from over 200 000 galaxies in Sloan Digital Sky Survey (SDSS) combination with Wilkinson Microwave Anisotropy Probe (WMAP) and other data. Our results are consistent a ``vanilla'' flat adiabatic cold dark matter model constant without tilt ${(n}_{s}=1),$ running tilt, tensor modes, or massive neutrinos. Adding SDSS information more than halves WMAP-only error bars on some parameters, tightening...
We perform a detailed analysis of the latest cosmic microwave background (CMB) measurements (including BOOMERaNG, DASI, Maxima and CBI), both alone jointly with other cosmological data sets involving, e.g., galaxy clustering Lyman Alpha Forest. first address question whether CMB are internally consistent once calibration beam uncertainties taken into account, performing series statistical tests. With few minor caveats, our answer is yes, we compress all single set 24 bandpowers associated...
Twenty-one centimeter tomography is emerging as a powerful tool to explore the end of cosmic dark ages and reionization epoch, but it will only be good our ability accurately model remove astrophysical foreground contamination. Previous treatments this problem have focused on angular structure signal foregrounds what can achieved with limited spectral resolution (bandwidths in 1 MHz range). In paper we introduce evaluate ``blind'' method extract multifrequency 21cm by taking advantage smooth...
Abstract Preterm‐born neonates are prone to impaired neurodevelopment that may be associated with disrupted whole‐brain structural connectivity. The present study aimed investigate the longitudinal developmental pattern of network from preterm birth term‐equivalent age (TEA), and identify how prematurity influences topological organization properties local brain regions. Multi‐shell diffusion‐weighted MRI 28 preterm‐born scanned a short time after (PB‐AB) at TEA (PB‐TEA), matched term‐born...
Cosmic shear measurements have now improved to the point where they deserve be treated on par with cosmic microwave background (CMB) and galaxy clustering data for cosmological parameter analysis, using full measured aperture mass variance curve rather than a mere phenomenological parametrization thereof. We perform detailed 9-parameter analysis of recent lensing [the Red Sequence Cluster Survey (RCS)], CMB (up Archeops) (2dF Collaboration) data, both separately jointly. 2dF are consistent...
Abstract Neural progenitor cells have shown the effectiveness in treatment of Parkinson's disease, but therapeutic efficacy remains variable. One important factors that determine is necessity pre‐differentiation into dopaminergic neurons before transplantation. This study therefore investigated mesencephalon‐derived human neural with or without alleviating a rat model disease. We found combination 50 ng/ml fibroblast growth factor 8, 10 glial cell line‐derived neurotrophic and μM forskolin...
An energy selective electron (ESE) refrigerator with heat leaks is established in a one-dimensional system. Based on the theory of electronic transport, expressions flux into hot and cold reservoirs are derived. When between two via phonons taken account, cooling rate, coefficient performance (COP) input power obtained. The characteristic curves such as rate versus COP, COP center position resonance level plotted by numerical calculation. influence width ESE analyzed detail. Lastly, average...
We construct a simple but self-consistent analytic ionization model for rapid exploration of 21 cm power spectrum observables in redshift space. It is fully described by the average fraction xe(z) and H II patch size R(z) has flexibility to accommodate various reionization scenarios. The associates regions with dark matter halos number density required recover xe treats space distortions self-consistently virial velocity such halos. Based on this model, we study line-of-sight structures...
This paper establishes the energy selective electron (ESE) engine with double resonances as a refrigerator in one dimensional (1D) system. It consists of two infinitely large reservoirs different temperatures and chemical potentials, they are perfectly thermally insulated from each other interaction only via 'idealized filter' whose widths all finite. Taking advantage density state Fermi distribution 1D system, heat flux into reservoir may then be calculated. Moreover, coefficient...
Abstract Fractal phenomena may be widely observed in a great number of complex systems. In this paper, motivated by the well-known Vicsek fractal, we propose generalized fractal whose seed is not necessarily single edge but an arbitrary tree, and study random walks on it for purpose understanding how underlying topology influences dynamic behaviors. Meanwhile, determine exact solution to mean first-passage time version more convenient mapping-based manner, while other methods suitable...
Here, we propose a class of scale-free networks G(t;m) with intriguing properties, which cannot be simultaneously held by all the theoretical models power-law degree distribution in existing literature, including following: (i) average degrees 〈k〉 generated are no longer constant limit large graph size, implying that they not sparse but dense; (ii) parameters γ these precisely calculated equal to 2; and (iii) their diameters D invariant growth process models. While our have deterministic...
Microglia are believed to participate in the mediation of neurodegeneration through producing a variety cytotoxic factors upon activation. Pharmacological intervention microglial activation may therefore exert neuroprotective effect. In exploring pharmacological agents that can affect activation, we found this study triptolide possesses powerful inhibitory influence over microglia. Pretreatment with was able dose-dependently reduce lipopolysaccharide (LPS)-induced nitrite accumulation and...
While previous works have shown that an overwhelming number of scale-free networks are sparse, there still exist some real-world including social networks, urban information which by observation dense. In this paper, we propose a novel framework for generating graphs with dense feature using two simple yet helpful operations, first-order subdivision and Line-operation. From the theoretical point view, our method can be used not only to produce desired density feature, i.e. power-law exponent...
Degree distribution, or equivalently called degree sequence, has been commonly used to study a large number of complex networks in the past few years. This reveals some intriguing results, for instance, popularity power-law distribution most these under consideration. Along such research line, this paper, we generate an ensemble random graphs with identical P(k)∼k-γ (γ=3) as proved shortly, denoted graph space N(p,q,t), where probability parameters p and q hold on p+q=1. Next, topological...

Two-dimensional (2D) correlation spectroscopy provides an important approach to the study of subtle spectral variations caused by intermolecular interactions. In our previous work, DAOSD (Double Asynchronous Orthogonal Sample Design) scheme was intro
Emotion recognition plays an important part in interpersonal interaction, especially for Human-Computer Interaction (HCI). Emotions are not only tightly intertwined neurologically with the mechanisms responsible cognition, but that they also play a pivotal role decision making, problem solving, communicating, negotiating, and adapting to unpredictable environments. can be recognized by many measurements such as gesture, facial images, neuro imaging physiological signals. Among which,...
