Computing the Singularities of Rational Surfaces [PDF]
, 2011 Given a rational projective parametrization $\cP(\ttt,\sss,\vvv)$ of a rational projective surface $\cS$ we present an algorithm such that, with the exception of a finite set (maybe empty) $\cB$ of projective base points of $\cP$, decomposes the projective parameter plane as $\projdos\setminus \cB=\cup_{k=1}^{\ell} \cSm_k$ such that if $(\ttt_0:\sss_0:\

Scintillation Response of 0D Cs3Cu2I5 Thin Layers to Light‐ and Heavy‐Ion Irradiation
Advanced Photonics Research, EarlyView.Driven by increasing interest in uncovering the remarkable photoluminescence quantum yield of Cs3Cu2I5, polycrystalline thin layers are synthesized to investigate its radioluminescence response to energetic ions. Its spectroscopic capability is assessed in a wide range of ion mass and internal excitation processes are explored.

Advanced Electronic Materials, EarlyView.High‐quality epitaxial five‐layer Sr2Bi4Ti5O18Aurivillius films are grown on SrTiO3 by pulsed laser deposition. The electrocaloric effect derived from measurements of the in‐plane ferroelectric polarization reveals a maximum temperature change of ΔT ∼ 0.95 °C under an electric field of 150 kV cm⁻¹ at 135 °C.

Comunicación y desarrollo [PDF]
Chasqui, 1982 El rol de los medios de comunicación de masas y su eventual funcionamiento en un proceso de desarrollo económico y político de una región o país determinado, es la reflexión principal a la que se abocan los autores. Para ello parten de la base que los medios sólo son instrumentos para un proceso, ya que, en sí mismos, no pueden determinar casi nada ...

A Novel Ti12‐Based Metal‐Organic Framework for Photocatalytic Hydrogen Evolution
Advanced Energy Materials, EarlyView.MIP‐209(Ti) is a new microporous MOF built up from Ti₁₂O₁₅ clusters and substituted terephthalate linkers, enabling isoreticular chemistry and clusters tunability for photocatalytic applications. Cr3⁺ doping (≤5 at%) on Ti‐oxoclusters drastically enhances water stability and boosts hydrogen production from water under simulated solar light irradiation.

Proposal for a Correction to the Temporal Correlation Coefficient Calculation for Temporal Networks [PDF]
arXiv, 2014 Measuring the topological overlap of two graphs becomes important when assessing the changes between temporally adjacent graphs in a time-evolving network. Current methods depend on the fraction of nodes that have persisting edges. This breaks down when there are nodes with no edges, persisting or otherwise. The following outlines a proposed correction
