Time-resolved extinction rates of stochastic populations

open access: yes, 2010
Extinction of a long-lived isolated stochastic population can be described as an exponentially slow decay of quasi-stationary probability distribution of the population size.

Single prazosin infusion in prelimbic cortex Fosters extinction of amphetamine-induced conditioned place preference [PDF]

open access: yes, 2017
Exposure to drug-associated cues to induce extinction is a useful strategy to contrast cue-induced drug seeking. Norepinephrine (NE) transmission in medial prefrontal cortex has a role in the acquisition and extinction of conditioned place preference ...

Context and behavioral processes in extinction.

open access: yesLearning & memory (Cold Spring Harbor, N.Y.), 2004
This article provides a selective review and integration of the behavioral literature on Pavlovian extinction. The first part reviews evidence that extinction does not destroy the original learning, but instead generates new learning that is especially ...

Tailoring Redox Active Sites with Dual‐Interfacial Electric Fields for Concurrent Photocatalytic Biomass Valorization and H2 Production

open access: yesAdvanced Functional Materials, EarlyView.
A rationally engineered bifunctional photocatalyst is reported, which achieves simultaneous selective oxidation of biomass‐derived 5‐hydroxymethylfurfural (HMF) to 2,5‐diformylfuran (DFF) and efficient H2 evolution. By precisely positioning Au and Co3O4 on Zn3In2S6 nanosheet, dual interfacial electric fields are well constructed to spatially separate ...

Performance Art in the Age of Extinction

open access: yesPhilosophies
This paper aims to map out the transformations in contemporary performance art during the current ‘age of extinction’. The first section extends Claire Bishop’s notion of “delegated performance” in order to categorize a turn towards the inclusion of ...

The Near-Infrared Extinction Law in Regions of High Av

open access: yes, 2005
We present a spectroscopic study of the shape of the dust-extinction law between 1.0 and 2.2um towards a set of nine ultracompact HII regions with Av > 15 mag.

Harnessing Non‐Covalent Protein–Protein Interaction Domains for Production of Biocatalytic Materials Systems

open access: yesAdvanced Functional Materials, EarlyView.
Non‐covalent protein–protein interactions mediated by SH3, PDZ, or GBD domains enable the self‐assembly of stable and biocatalytically active hydrogel materials. These soft materials can be processed into monodisperse foams that, once dried, exhibit enhanced mechanical stability and activity and are easily integrated into microstructured flow ...

Island biogeography: colonization, evolution, and excitation; analogy and potential implication to oncology

open access: yesFrontiers in Ecology and Evolution
Life on islands and cancer evolves under unique environmental pressures and acquire distinctive features. This manuscript is an attempt to find analogies between carcinogenesis and island biota colonization, evolution, and extinction.

The extinction law from photometric data: linear regression methods

open access: yes, 2012
Context. The properties of dust grains, in particular their size distribution, are expected to differ from the interstellar medium to the high-density regions within molecular clouds.
