Modeling the Infrared Extinction toward the Galactic Center [PDF]
, 2013 We model the ~1--19$\mum$ infrared (IR) extinction curve toward the Galactic Center (GC) in terms of the standard silicate-graphite interstellar dust model. The grains are taken to have a power law size distribution with an exponential decay above some size.

Evolution of dust extinction curves in galaxy simulation
, 2017 To understand the evolution of extinction curve, we calculate the dust evolution in a galaxy using smoothed particle hydrodynamics simulations incorporating stellar dust production, dust destruction in supernova shocks, grain growth by accretion and ...

Public Understanding of Science, 2015 Mistrust of science has seeped into public perception of the most fundamental aspect of conservation— extinction. The term ought to be straightforward, and yet, there is a disconnect between scientific discussion and public views. This is not a mere semantic issue, rather one of communication.

Vivid Structural Coloration in Transparent MXene‐Cellulose Nanocrystals Composite Films
Advanced Functional Materials, EarlyView.Vivid structural coloration in reflectance and high transparency in transmittance modes are observed in biopolymer‐layered composite films. The ultrathin multilayered structures have unique optical appearance, near‐infrared bandgap, and strong optical reflection caused by alternating MXene and cellulose nanocrystals layers with high refractive index ...

Nitrogen Pollution and the Meltdown of Urban Ecosystems
Land, 2016 Urban ecosystems are carrying an extinction debt. Mitigating this debt will require the development of a predictive framework that improves our understanding of the factors causing decline of native biodiversity in urban areas. I argue that nitrogen is a

Journal of Biological Dynamics, 2020 In this paper, we first investigate a stochastic two-predators one-prey model with Lévy noise and distributed delays. The global dynamical behaviour is discussed.

A 3D extinction map of the Northern Galactic Plane based on IPHAS photometry [PDF]
, 2014 We present a three dimensional map of extinction in the Northern Galactic Plane derived using photometry from the IPHAS survey. The map has fine angular ($\sim 10$ arcmin) and distance (100 pc) sampling allied to a significant depth ($\gtrsim 5$ kpc). We construct the map using a method based on a hierarchical Bayesian model as previously described by ...

Environmental enrichment facilitates cocaine-cue extinction, deters reacquisition of cocaine self-administration and alters AMPAR GluA1 expression and phosphorylation [PDF]
, 2017 This study investigated the combination of environmental enrichment (EE) with cocaine‐cue extinction training on reacquisition of cocaine self‐administration.

Near‐Infrared Circularly Polarized Electroluminescence with Switchable Handedness in Organic LEDs
Advanced Functional Materials, EarlyView.The first fully‐organic circularly polarized near‐infrared OLED, using a co‐assembled active layer of ITIC and a chiral inducer, exhibits dissymmetry values up to 0.074 and 1.65 Wsr−1m−2 radiance. The circular polarization sign can be switched by manipulating the position of the recombination zone, resulting in enhanced device performance and stability.

Frontiers in Molecular Neuroscience, 2018 Extracellular regulated kinase 1/2 (ERK1/2) has been strongly implicated in several cellular processes. In the brain ERK1/2 activity has been primarily involved in long-term memory (LTM) formation and expression.
