Gain Modulation by Corticostriatal and Thalamostriatal Input Signals during Reward-Conditioned Behavior. [PDF]

open access: yes, 2019
The cortex and thalamus send excitatory projections to the striatum, but little is known about how these inputs, either individually or collectively, regulate striatal dynamics during behavior.

Variation in the perception of an L2 contrast : a combined phonetic and phonological account [PDF]

open access: yes, 2009
The present study argues that variation across listeners in the perception of a non-native contrast is due to two factors: the listener-specic weighting of auditory dimensions and the listener-specic construction of new segmental representations.

Comparison of a linear and a nonlinear washout for motion simulators utilizing objective and subjective data from CTOL transport landing approaches [PDF]

open access: yes
Objective and subjective data gathered in the processes of comparing a linear and a nonlinear washout for motion simulators reveal that there is no difference in the pilot performance measurements used during instrument landing system (ILS) approaches ...

Spatiotemporal Dynamics and Future Projections of Carbon Use Efficiency on the Mongolian Plateau: A Remote Sensing and Machine Learning Approach

open access: yesRemote Sensing
The Mongolian Plateau, a critical area for global climate change response, faces increasing vulnerability from climate change and human activities impacting its arid ecosystems. This study integrates GeoDetector and machine learning to predict vegetation

Use of the tilt cue in a simulated heading tracking task [PDF]

open access: yes, 1978
The task was performed with subjects using visual-only cues and combined visual and roll-axis motion cues. Half of the experimental trials were conducted with the simulator rotating about the horizontal axis; to suppress the tilt cue, the remaining ...

Changes in global carbon use efficiency in the 21st century and the potential controlling factors

open access: yesEnvironmental Research Letters
Extensive studies have demonstrated the spatiotemporal changes in carbon use efficiency (CUE) and its driving factors over the past three decades. However, how the global CUE will change and to what extent the CUE is affected by the dominant factor in ...

Pseudo-random operators of the circular ensembles

open access: yes, 2004
We demonstrate quantum algorithms to implement pseudo-random operators that closely reproduce statistical properties of random matrices from the three universal classes: unitary, symmetric, and symplectic.

Effect of time delay on feedback control of a flashing ratchet

open access: yes, 2007
It was recently shown that the use of feedback control can improve the performance of a flashing ratchet. We investigate the effect of a time delay in the implementation of feedback control in a closed-loop collective flashing ratchet, using Langevin ...

Vapor pressure deficit shapes the distributions of carbon use efficiency across Siberia

open access: yesCarbon Balance and Management
As a key indicator of terrestrial carbon cycle, carbon use efficiency (CUE) represents the efficiency of carbon fixation and carbon allocation strategy, shaping ecosystem function and services.

Metacognition of visual short-term memory: Dissociation between objective and subjective components of VSTM

open access: yesFrontiers in Psychology, 2013
The relationship between the objective accuracy of visual-short term memory (VSTM) representations and their subjective conscious experience is unknown.
