Coexistence Analysis between Radar and Cellular System in LoS Channel

open access: yes, 2016
Sharing spectrum with incumbents such as radar systems is an attractive solution for cellular operators in order to meet the ever growing bandwidth requirements and ease the spectrum crunch problem.

Lock-in detection for pulsed electrically detected magnetic resonance [PDF]

open access: yes, 2011
We show that in pulsed electrically detected magnetic resonance (pEDMR) signal modulation in combination with a lock-in detection scheme can reduce the low-frequency noise level by one order of magnitude and in addition removes the microwave-induced non ...

A Quantitative Analysis of Pulsed Signals Emitted by Wild Bottlenose Dolphins.

open access: yesPLoS ONE, 2016
Common bottlenose dolphins (Tursiops truncatus), produce a wide variety of vocal emissions for communication and echolocation, of which the pulsed repertoire has been the most difficult to categorize.

Similar Expectation Effects for Immediate and Delayed Stimulus Repetitions

open access: yesFrontiers in Neuroscience, 2019
A prior cue or stimulus allows prediction of the future occurrence of an event and therefore reduces the associated neural activity in several cortical areas.

Time-Based Transition Expectancy in Task Switching: Do We Need to Know the Task to Switch to?

open access: yesJournal of Cognition, 2021
Recent research has shown that humans are able to implicitly adapt to time-transition contingencies in a task-switching paradigm, indicated by better performance in trials where the task transition (switch vs.

Efficient transfer entropy analysis of non-stationary neural time series

open access: yes, 2014
Information theory allows us to investigate information processing in neural systems in terms of information transfer, storage and modification. Especially the measure of information transfer, transfer entropy, has seen a dramatic surge of interest in ...

Fast and User-friendly Quantum Key Distribution [PDF]

open access: yes, 1999
Some guidelines for the comparison of different quantum key distribution experiments are proposed. An improved 'plug & play' interferometric system allowing fast key exchange is then introduced.

The relationship between task repetition and language proficiency [PDF]

open access: yesApplied Research on English Language, 2014
Task repetition is now considered as an important task-based implementation variable which can affect complexity, accuracy, and fluency of L2 speech. However, in order to move towards theorizing the role of task repetition in second language acquisition,

Does repetitive task training improve functional activity after stroke? A Cochrane systematic review and meta-analysis. [PDF]

open access: yes, 2010
Repetitive task training resulted in modest improvement across a range of lower limb outcome measures, but not upper limb outcome measures. Training may be sufficient to have a small impact on activities of daily living.
