Eyeblink Classical Conditioning and Post Traumatic Stress Disorder – A Model Systems Approach

Frontiers in Psychiatry, 2015
Not everyone exposed to trauma suffers flashbacks, bad dreams, numbing, fear, anxiety, sleeplessness, hyper-vigilance, hyperarousal, or an inability to cope, but those who do may suffer from post traumatic stress disorder (PTSD).

Extinction of cue-evoked drug-seeking relies on degrading hierarchical instrumental expectancies

, 2014
There has long been need for a behavioural intervention that attenuates cue-evoked drug-seeking, but the optimal method remains obscure. To address this, we report three approaches to extinguish cue-evoked drug-seeking measured in a Pavlovian to ...

Rethinking Extinction [PDF]

Neuron, 2015
Extinction serves as the leading theoretical framework and experimental model to describe how learned behaviors diminish through absence of anticipated reinforcement. In the past decade, extinction has moved beyond the realm of associative learning theory and behavioral experimentation in animals and has become a topic of considerable interest in the ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Facilitating evolutionary rescue from a wildlife health threat with cross-sectoral strategies: a case study on white-nose syndrome

Ecology and Society
Evolutionary rescue, the ability of a species to evolve under new selective pressures and rebound from threats, occurs within a social-ecological system.

Activation of dopamine receptors in the nucleus accumbens promotes sucrose-reinforced cued approach behavior

Frontiers in Behavioral Neuroscience, 2016
Dopamine receptor activation in the nucleus accumbens (NAc) promotes vigorous environmentally-cued food-seeking in hungry rats. Rats fed ad libitum, however, respond to fewer food-predictive cues, particularly when the value of food reward is low.

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

Advanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

The conservation impact of botanical drones: Documenting and collecting rare plants from vertical cliffs and other hard‐to‐reach areas

Ecological Solutions and Evidence
A high percentage of island floras are at risk of extinction and have been reduced to relic populations, often in remote hard‐to‐reach areas. Uncrewed aircraft systems (UAS aka drones) are now being utilized to assist in the survey and collection of rare

Numerical model for estimating contribution of different components of crystalline cloud to extinction of optical radiation. Part 1. Scheme of qualitative estimation

Известия Томского политехнического университета: Промышленная кибернетика
An analytical expression for extinction coefficient of optical radiation is proposed, taking into account various microphysical parameters of dispersed medium. The formula is product of the extinction factor and modified geometric value.

The fossil record of early tetrapods: Worker effort and the end-Permian mass extinction [PDF]

, 2010
It is important to understand the quality of the fossil record of early tetrapods (Tetrapoda. minus Lissamphibia and Amniota) because of their key role in the transition of vertebrates from water to land, their dominance of terrestrial faunas for over ...
