Optimal extinction rates for the fast diffusion equation with strong absorption [PDF]
, 2017 Optimal extinction rates near the extinction time are derived for non-negative solutions to a fast diffusion equation with strong absorption, the power of the absorption exceeding that of the diffusion.

Aerosol studies in mid-latitude coastal environments in Australia [PDF]
, 1986 The results of the evaluation of several inversion procedures that were used to select one which provides the most accurate atmospheric extinction profiles for small aerosol extinction coefficients (that often predominate in the maritime airmass) are ...

, 2017 Understanding the effects of dust extinction is important to properly interpret observations. The optical total-to-selective extinction ratio, Rv = Av/E(B-V), is widely used to describe extinction variations in ultraviolet and optical bands. Since the Rv=

Enhanced Terahertz Spectroscopy of a Monolayer Transition Metal Dichalcogenide
Advanced Functional Materials, EarlyView.An ad‐hoc engineered metallic surface is employed to perform enhanced terahertz spectroscopy of a monolayer transition metal dichalcogenide (TMD). Thanks to a local absorption boost of 104, this technique allows for the extraction of the phonon resonance features and effective permittivity of the 2D material, paving the way for the rational design of ...

Advanced Functional Materials, EarlyView.The plasma edge of transparent conducting oxide SrNbO3 shifts from ∼2 eV in the visible range to 1.37 eV in the near‐infrared region by off‐stoichiometry using the vacancy sites as quasi‐substitutional virtual elements. This work advances the stoichiometry engineering of perovskite oxides using oxide molecular beam epitaxy, allowing synthesis beyond ...

Branching random walks with uncountably many extinction probability vectors [PDF]
arXiv, 2018 Given a branching random walk on a set $X$, we study its extinction probability vectors $\mathbf q(\cdot,A)$. Their components are the probability that the process goes extinct in a fixed $A\subseteq X$, when starting from a vertex $x\in X$. The set of extinction probability vectors (obtained letting $A$ vary among all subsets of $X$) is a subset of ...

FUSE Measurements of Far Ultraviolet Extinction. I. Galactic Sight Lines
, 2005 We present extinction curves that include data down to far ultraviolet wavelengths (FUV; 1050 - 1200 A) for nine Galactic sight lines. The FUV extinction was measured using data from the Far Ultraviolet Spectroscopic Explorer. The sight lines were chosen

Advanced Functional Materials, EarlyView.The non‐fullerene acceptor o‐IDT‐BT‐DCV is used in both binary and ternary blends to investigate the role that it plays in each device architecture. The charge generation pathways are found to differ between the binary and ternary blends with o‐IDT‐BT‐DCV becoming a second donor in the ternary blend.

Critical Domain Problem for the Reaction–Telegraph Equation Model of Population Dynamics
Mathematics, 2018 A telegraph equation is believed to be an appropriate model of population dynamics as it accounts for the directional persistence of individual animal movement.
