A novel nano-particle strengthened titanium alloy with exceptional specific strength (open access)

A novel nano-particle strengthened titanium alloy with exceptional specific strength

This article microstructurally tailors an exceptionally high-strength titanium alloy, Ti-6Al-2Sn-4Zr-6Mo (Ti6246) through friction stir processing (FSP) in order to provide enhanced weight savings and improved fuel efficiency. The specific strength attained in one of the conditions is close to 450 MPa m³/mg, which is about 22% to 85% greater than any commercially available metallic material. This novel nano particle strengthened Ti alloy is a potential replacement for many structural alloys, enabling significant weight reduction opportunities.

LBD29-Involved Auxin Signaling Represses NAC Master Regulators and Fiber Wall Biosynthesis (open access)

LBD29-Involved Auxin Signaling Represses NAC Master Regulators and Fiber Wall Biosynthesis

This article uses a large-scale mutant screening to identify a dominant activation-tagging mutant, fiberless-d (fls-d), showing defective SCW development in stem fibers, similar to that of the nac secondary wall thickening promoting factor1-1 (nst1-1)nst3-3 double mutant. The results demonstrate auxin is upstream of LBD29 in repressing NAC master regulators, and therefore sheds new light on the regulation of SCW biosynthesis in Arabidopsis.

Correlation consistent basis sets designed for density functional theory: Second-row (Al-Ar) (open access)

Correlation consistent basis sets designed for density functional theory: Second-row (Al-Ar)

Article presenting cc-pV(n+d)Z correlation consistent basis sets of double- through quintuple-ζ quality for the atoms Al-Ar that have been modified for use with density functional theory (DFT). These basis set modifications include truncation of high-angular momentum basis functions, recontraction of the s- and p-functions, and reoptimization of basis function exponents with generalized gradient approximation and hybrid-DFT functionals. The effects of basis set truncation, recontraction, and reoptimization are shown to improve convergence behavior in atomic energies as well as dissociation energies and enthalpies of formation.

Persistent spin helix in Rashba-Dresselhaus ferroelectric CsBiNb2O7 (open access)

Persistent spin helix in Rashba-Dresselhaus ferroelectric CsBiNb2O7

Article reporting that CsBiNb₂O₇, a layered perovskite of Dion-Jacobson type, is a robust ferroelectric with sufficiently strong spin-orbit coupling and spin texture reversible by electric field. The study reveals that its topmost valence band's spin texture is quasi-independent from the momentum, as a result of the low symmetry of its ferroelectric phase. The peculiar spin-polarization pattern in the momentum space may yield the so-called “persistent spin helix,” a specific spin-wave mode which protects the spin from decoherence in the diffusive transport regime, potentially ensuring a very long spin lifetime in this material.

Influence of coherent population trapping on Raman scattering (open access)

Influence of coherent population trapping on Raman scattering

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.

A gene based approach to test genetic association based on an optimally weighted combination of multiple traits (open access)

A gene based approach to test genetic association based on an optimally weighted combination of multiple traits

In this article, the authors propose a statistical method by Testing an Optimally Weighted Combination of Multiple traits (TOW-CM) to test the association between multiple traits and multiple variants in a genomic region (a gene or pathway). They investigate the performance of the proposed method through extensive simulation studies. Their simulation studies show that the proposed method has correct type I error rates and is either the most powerful test or comparable with the most powerful tests. Additionally, they illustrate the usefulness of TOW-CM based on a COPDGene study.
