The Mid-Infrared Extinction Law and its Variation in the Coalsack Nebula [PDF]

, 2013
In recent years the wavelength dependence of interstellar extinction from the ultraviolet (UV), optical, through the near- and mid-infrared (IR) has been studied extensively.

Is hybridisation with non‐native congeneric species a threat to the UK native bluebell Hyacinthoides non‐scripta?

Plants, People, Planet, 2023
Societal Impact Statement Hybridisation is an important evolutionary force in plants, but it can potentially lead to genetic swamping and extinction of one or both parental species.

The extinction of the dinosaurs [PDF]

Biological Reviews, 2014
ABSTRACTNon‐avian dinosaurs went extinct 66 million years ago, geologically coincident with the impact of a large bolide (comet or asteroid) during an interval of massive volcanic eruptions and changes in temperature and sea level. There has long been fervent debate about how these events affected dinosaurs.

Understanding Associative Learning Through Higher-Order Conditioning

Frontiers in Behavioral Neuroscience, 2022
Associative learning is often considered to require the physical presence of stimuli in the environment in order for them to be linked. This, however, is not a necessary condition for learning.

Impaired contextual modulation of memories in PTSD: an fMRI and psychophysiological study of extinction retention and fear renewal [PDF]

, 2014
Post-traumatic stress disorder (PTSD) patients display pervasive fear memories, expressed indiscriminately. Proposed mechanisms include enhanced fear learning and impaired extinction or extinction recall. Documented extinction recall deficits and failure

The strange history of atmospheric oxygen

Physiological Reports, 2022
Many of us think a lot about oxygen. This includes how the normal body handles oxygen in health, but particularly how this is complicated by lung disease. Few of us are aware that as human inhabitants of the earth, we have a unique privilege.

A Quantitative Comparison of SMC, LMC, and Milky Way UV to NIR Extinction Curves

, 2003
We present an exhaustive, quantitative comparison of all of the known extinction curves in the Small and Large Magellanic Clouds (SMC and LMC) with our understanding of the general behavior of Milky Way extinction curves.

Hurst Coefficient in long time series of population size: Model for two plant populations with different reproductive strategies [PDF]

, 2010
Can the fractal dimension of fluctuations in population size be used to estimate extinction risk? The problem with estimating this fractal dimension is that the lengths of the time series are usually too short for conclusive results.
