Article on the equivalence of dipole correction and Coulomb cutoff techniques in supercell calculations. In this work, the authors compare the dipole correction and Coulomb cutoff methods under the same conditions in the framework of plane-wave based density-functional theory.

This article investigates the pressure-induced phase transitions in SnSe using the first-principles density functional calculations.

The article investigates the pressure-induced phase transitions in tin selenide (SnSe). using the first-principles density functional calculations. The experimental results in the nanostructured SnSe revealed a phase transition at 4 GPa whereas that in the well-crystallized samples showed at 10 GPa.

This article explores Ultraviolet (UV) photoluminescence (PL) data taken on a double Au implanted Si matrix and studied over a wide temperature range of 28-220K. The results of this study at lower temperatures indicate the emission to be coming from Si nanoclusters (NCs) embedded in the matrix.

Article exploring the topology of black holes.

This article presents new ALMA band-7 data for a sample of six luminous quasars at z ≃ 4.8, powered by fast-growing supermassive black holes (SMBHs) with rather uniform properties.

This article discusses the long-term (≈15 years, observed frame) X-ray variability analyses of the 68 brightest radio-quiet active galactic nuclei (AGNs) in the 6 Ms Chandra Deep Field-South survey.

This article presents the results of a 2 year long optical monitoring program of the narrow-line Seyfert 1 galaxy Ark 564.

This article studies the hard X-ray spectral properties of 10 highly luminous radio-quiet active galactic nuclei at z = 1.3-3.2, including new XMM-Newton observations of four of these sources.

This article presents the results of an intensive 2 month campaign of approximately daily spectrophotometric monitoring of the narrow-line Seyfert 1 galaxy Ark 564 with the Hubble Space Telescope.

This is a Publisher's Note for the article 'Beyond the Death of Linear Response: 1/f Optimal Information Transport' [Phys. Rev. Lett. 105, 040601 (2010)].

This article reports the holographic fabrication of three types of 3D graded photonic super-crystals (GPSCs) through nine beam interferences and their characteristic diffraction patterns.

This article presents a technique to search for the presence of crucial events in music, based on the analysis of the music volume.

This article presents an approximate analytical solution for the connectivity of a network model with a "non-simultaneous" linking scheme.

This paper discusses research on acoustic cancellation in architecture.

Presentation for the 2008 University Scholars Day at the University of North Texas discussing research on the look of sound and acoustic cancellation in architecture.

Poster presentation for the 2008 University Scholars Day at the University of North Texas. This poster discusses research on Bose-Einstein condensates (BECs) and their possible applications in quantum computing and optical processing.

Article reports the discovery of an extreme X-ray flux rise (by a factor of ≳20) of the weak-line quasar Sloan Digital Sky Survey (SDSS) J153913.47+395423.4 (hereafter SDSS J1539+3954) at z = 1.935. SDSS J1539+3954 is the most-luminous object among radio-quiet type 1 active galactic nuclei (AGNs) where such dramatic X-ray variability has been observed.
