TL;DR: In this paper, the authors studied the evolution of the photoemission line shape as a function of momentum, temperature, and doping, and found that the peak-dip-hump structure arises from the interaction of electrons with a collective mode of wave vector (pi, pi).
Abstract: The photoemission line shape near (pi, 0) in Bi(2)Sr(2)CaCu(2)O(8+delta) below T(c) is characterized by a sharp peak, followed at higher energy by a dip and hump. We study the evolution of this line shape as a function of momentum, temperature, and doping. We find the hump scales with the peak and persists above T(c) in the pseudogap state. We present strong evidence that the peak-dip-hump structure arises from the interaction of electrons with a collective mode of wave vector (pi, pi). The inferred mode energy and its doping dependence agree well with a magnetic resonance observed by neutron scattering.

TL;DR: It is shown here that nucleophosmin/B23 functions as a histone chaperone protein such as nucleoplasmin, TAF‐I, and NAP‐I as a stimulatory factor for replication from the adenovirus chromatin.

TL;DR: In this paper, a measurement of the production processes of the recently discovered Higgs boson is performed in the two-photon final state using 4.5 fb(-1) of proton-proton collisions data at root s = 7 TeV and 20.4 GeV.
Abstract: A measurement of the production processes of the recently discovered Higgs boson is performed in the two-photon final state using 4.5 fb(-1) of proton-proton collisions data at root s = 7 TeV and 20.3 fb(-1) at root s = 8 TeV collected by the ATLAS detector at the Large Hadron Collider. The number of observed Higgs boson decays to diphotons divided by the corresponding Standard Model prediction, called the signal strength, is found to be mu = 1.17 +/- 0.27 at the value of the Higgs boson mass measured by ATLAS, m(H) = 125.4 GeV. The analysis is optimized to measure the signal strengths for individual Higgs boson production processes at this value of m(H). They are found to be mu(ggF) = 1.32 +/- 0.38, mu(VBF) = 0.8 +/- 0.7, mu(WH) = 1.0 +/- 1.6, mu(ZH) = 0.1(-0.1)(+3.7), and mu t (t) over barH = 1.6(-1.8)(+2.7), for Higgs boson production through gluon fusion, vector-boson fusion, and in association with a W or Z boson or a top-quark pair, respectively. Compared with the previously published ATLAS analysis, the results reported here also benefit from a new energy calibration procedure for photons and the subsequent reduction of the systematic uncertainty on the diphoton mass resolution. No significant deviations from the predictions of the Standard Model are found.

TL;DR: A signal design is proposed for a CDMA system that is approximately synchronized with ideal autocorrelation for small shifts and zero cross correlation for all shifts, and the system works without cochannel interference, even when the signals are modulated by data.
Abstract: A signal design is proposed for a CDMA system that is approximately synchronized. The signals are called pseudoperiodic sequences. The set of pseudoperiodic polyphase sequences are introduced from a set of periodic polyphase sequences with ideal autocorrelation for small shifts and zero cross correlation for all shifts. The system works without cochannel interference, even when the signals are modulated by data. >

TL;DR: The measured absorption spectra agreed well with the ab initio calculations of band structure based on the local density function approximation, and the absorption bands are assigned to the dipole transitions between the Van Hove singularities.
Abstract: We report the polarized optical absorption spectra of single-walled $4\AA{}$ carbon nanotubes arrayed in the channels of an $\mathrm{AlPO}{}_{4}\ensuremath{-}5$ single crystal. When the light electric field $(E)$ is polarized parallel to the tube direction $(c)$, the spectra display a sharp peak at 1.37 eV, with two broadbands at 2.1 and 3.1 eV. In the $E\ensuremath{\perp}c$ configuration, the tube is nearly transparent in the measured energy region 0.5--4.1 eV. The optical dipole selection rules are discussed, and the absorption bands are assigned to the dipole transitions between the Van Hove singularities. The measured absorption spectra agreed well with the ab initio calculations of band structure based on the local density function approximation.
