This article is a response to an article by M. Adell et al. [Phy. Rev. Lett. 94, 139701 (2005)] about semiconductor-based spintronics research.

This paper from the 23rd Conference on Application of Accelerators in Research and Industry conference proceedings describes an experiment that could be carried out at the CERN Antiproton Decelerator facility to determine the direction of acceleration of antihydrogen in the earth's gravitational field.

Article presents a reliable, scalable, and inexpensive technology for the fabrication of ordered arrays of metal nanoparticles with large areal coverage on various substrates. Using a simple model, the experimental results were interpreted and supported by numerical estimations.

Article on the activation of water on the TiO2 (110) surface.

This article discusses an analysis of multiple ignition sites, primary circuits, and burst phase delay distributions.

This article, using calculations from first principles, reveals for the first time giant intrinsic spin Hall conductivities (SHC) in these materials. In particular, the article shows that the SHC resonances can be easily tuned by combination of strain and doping and, in some cases, strain can be used to induce semiconductor to metal transition that makes a giant spin Hall effect possible even in absence of doping.

Article discussing linear response and fluctuation dissipation theorem for non-Poissonian renewal processes.

This article studies low-energy interactions of positrons with xenon experimentally and theoretically. Results are compared with previous literature.

This article discusses the relationship between metallicity and luminosity in active galactic nuclei by introducing new metallicity measurements for a sample of narrow-line Seyfert 1 galaxies.

Article studying high light absorption in two devices: a stack of Au-pattern/insulator/Au-film and a stack of Au-pattern/weakly-absorbing-material/Au-film where the Au-pattern was structured in graded photonic super-crystal. Multiple-band absorption, including one near 1500 nm, in a stack of Au-pattern/spacer/Au-film was observed.

This article presents the biological effects of a novel hydrogel based quantum dot nano-structure on E. coli bacteria.

This article presents Gemini-North K-band spectra of two representative members of the class of high-redshift quasars with exceptionally weak rest-frame ultraviolet emission lines.

This article presents Chandra observations of nine high-redshift quasars discovered by the Sloan Digital Sky Survey with weak or undetectable high-ionization emission lines in their UV spectra.

This article discusses a dynamical origin of memory and renewal.

Article on the first principles theory of artificial metal chains on NiAl(110) surface.

This article discusses low-level copper concentration measurements in silicon wafers using trace-element accelerator mass spectrometry.

Article on carrier-envelope phase effect on atomic excitation by few-cycle rf pulses.

This article presents near-infrared spectroscopy of 18 luminous quasars at 2.15 < z < 3.70 that allows the authors to obtain reliable systemic redshifts for these sources.

Article develops a homogenization theory, representing the low-frequency limit for a phononic crystal of cylinders embedded in a viscous fluid.

Article considering the Raman scattering in molecular media. Applying two laser fields in a two-photon resonance with vibrational transition, the authors study the role of rotational levels for excitation of vibrational coherence. It is shown that the molecular vibrational coherence strongly depends on the effect of coherent population trapping for rotational levels. The obtained results are important for applications of Raman spectroscopy to molecular detection in engineering, chemical, and biological applications.

Article introducing the quasiharmonic approximation three-phonon method to calculate the thermodynamic properties of both nonmetallic and metallic compounds. This study demonstrates that QHA3P is an ideal framework for the high-throughput prediction of finite-temperature material properties, combining the accuracy of QHA with the computational efficiency of SC-QHA.

Authors of the article assert that they studied the ensemble X-ray variability properties of active galactic nuclei (AGN) over large ranges of timescale (20 ks ≤ T ≤ 14 yr), redshift (0 ≤ z ≲ 3), luminosity (1040 erg s−1 ≤ LX ≤ 1046 erg s−1), and black hole (BH) mass (106 ≤ M⊙ ≤ 109). The authors show that the data collected from archival observations and previous literature studies are fully consistent with a universal PSD form, which does not show any evidence for systematic evolution of shape or amplitude with redshift or luminosity, even if there may be differences between individual AGN at a given redshift or luminosity.
