The impact of emotional valence and stimulus habituation on fMRI signal reliability during emotion generation

open access: yesNeuroImage, 2023
Background: The emotional domain is often impaired across many neurological diseases, for this reason it represents a relevant target of rehabilitation interventions.

Relatedness influences signal reliability in evolving robots. [PDF]

open access: yesProc Biol Sci, 2011
Communication is an indispensable component of animal societies, yet many open questions remain regarding the factors affecting the evolution and reliability of signalling systems. A potentially important factor is the level of genetic relatedness between signallers and receivers.

Early warning signal reliability varies with COVID-19 waves. [PDF]

open access: yesBiol Lett, 2021
Early warning signals (EWSs) aim to predict changes in complex systems from phenomenological signals in time series data. These signals have recently been shown to precede the emergence of disease outbreaks, offering hope that policymakers can make ...

Diet-Mediated Pheromones and Signature Mixtures Can Enforce Signal Reliability

open access: yesFrontiers in Ecology and Evolution, 2017
Diet is arguably the most significant environmental factor shaping chemical signals in animals. In rare cases, dietary components are converted directly into pheromones or signature mixtures but more generally variation in an individual’s diet influences

Comparison of oxyhemoglobin and deoxyhemoglobin signal reliability with and without global mean removal for digit manipulation motor tasks

open access: yesNeurophotonics, 2017
. Functional near-infrared spectroscopy (fNIRS) could be well suited for clinical use, such as measuring neural activity before and after treatment; however, reliability and specificity of fNIRS signals must be ensured so that differences can be ...

Maynard Smith: amplifying the reasons for signal reliability.

open access: yesJournal of Theoretical Biology, 2006
One of the many questions to which John Maynard Smith contributed was that of why most animal signals are reliable. He initially rejected the "handicap" argument but gradually accepted it, a process I briefly describe.

A novel arc signal and motor power synchronization-based method for precise contact fault diagnosis of GIS disconnector [PDF]

open access: yesScientific Reports
Gas-insulated switchgear (GIS) disconnectors play an important role in power systems, and their mechanical condition is critical for operational reliability. However, existing diagnostic methods frequently fail to accurately identify critical operational

Subjective perception of objects depends on the interaction between the validity of context-based expectations and signal reliability.

open access: yesVision Research, 2023
Predictive coding theories of visual perception assume that expectations based on prior knowledge modulate the processing of information. However, the underlying mechanisms remain debated. Some accounts propose that expectations enhance the perception of
