A 3D‐Printed SFE‐Graded Alloy Mitigates Cryogenic Discontinuous Plastic Flow and Hydrogen Embrittlement

open access: yesAdvanced Science, EarlyView.
A novel strategy features gradient composition and stacking fault energy‐tuned (CoCrMn)100‐2xFexNix fabricated via in situ alloying additive manufacturing. This design circumvents cryogenic discontinuous plastic flow and hydrogen embrittlement of metallic materials under quasi‐static loading and hydrogen‐rich environment relevant to lunar polar ...

Hybrid Spring‐Coupled Broadband Energy Harvester Integrated with CuSCN Functionalized Triboelectric Vibration Sensor for Self‐Sustainable Vehicular IoTs

open access: yesAdvanced Science, EarlyView.
A self‐sustainable vehicular vibration and indoor environment monitoring IoT platform is developed which integrates a hybrid spring‐coupled broadband energy harvester with a machine learning‐assisted PAN‐CuSCN nanofiber triboelectric vibration sensor for subtle‐to‐wide‐range vibration detection and road/speed classification.

Disrupted Top‐Down Modulation as a Mechanism of Impaired Multisensory Processing in Autistic Children

open access: yesAdvanced Science, EarlyView.
In this work, we show that multisensory integration in autistic children is characterized by attenuated ERP responses and α‐band desynchronization, together with reduced theta‐band communication between parieto‐occipital and frontal regions. The intermediate neural profile observed in unaffected siblings raises the possibility that altered cortical ...

Voluntary Spatial Attention has Different Effects on Voluntary and Reflexive Saccades

open access: yesThe Scientific World Journal, 2003
Although numerous studies have investigated the relationship between saccadic eye movements and spatial attention, one fundamental issue remains controversial.

Different effects of double-pulse TMS of the posterior parietal cortex on reflexive and voluntary saccades

open access: yesFrontiers in Human Neuroscience, 2011
Gap and overlap tasks are widely used to promote automatic versus controlled saccades. This study examines the hypothesis that the right posterior parietal cortex (PPC) is differently involved in the two tasks. Twelve healthy students participated in the

Influence of retinal image shifts and extra-retinal eye movement signals on binocular rivalry alternations. [PDF]

open access: yesPLoS ONE, 2013
Previous studies have indicated that saccadic eye movements correlate positively with perceptual alternations in binocular rivalry, presumably because the foveal image changes resulting from saccades, rather than the eye movement themselves, cause ...

Learning the optimal control of coordinated eye and head movements [PDF]

open access: yes, 2011
Various optimality principles have been proposed to explain the characteristics of coordinated eye and head movements during visual orienting behavior.

Atomic‐Scale Mechanisms of Anisotropic Thermal Decomposition in GeSn Alloys With Stepwise Pinning

open access: yesAdvanced Electronic Materials, EarlyView.
Combining in situ TEM with DFT calculations, this work elucidates atomic‐scale anisotropic thermal decomposition in GeSn films, identifying laminar receding in defect‐free regions and stepwise pinning at stacking faults. Driven by crystallographic anisotropy and defect‐mediated energetic penalties, these findings establish a physical framework for ...

Monetary reward speeds up voluntary conditional saccades

open access: yesFrontiers in Integrative Neuroscience, 2014
Past studies have shown that reward contingency is critical for sensorimotor learning, and reward expectation speeds up saccades in animals. Whether monetary reward speeds up saccades in human remains unknown.

Saccadic momentum and facilitation of return saccades contribute to an optimal foraging strategy. [PDF]

open access: yesPLoS Computational Biology, 2013
The interest in saccadic IOR is funneled by the hypothesis that it serves a clear functional purpose in the selection of fixation points: the facilitation of foraging. In this study, we arrive at a different interpretation of saccadic IOR. First, we find
