Scale-invariance of human EEG signals in sleep [PDF]

open access: yes, 2007
We investigate the dynamical properties of electroencephalogram (EEG) signals of human in sleep. By using a modified random walk method, We demonstrate that the scale-invariance is embedded in EEG signals after a detrending procedure.

Liquid‐Locked Bassanites for Scalable Fabrication of High‐Temperature Micro‐Supercapacitors Working at 300 °C

open access: yesAdvanced Functional Materials, EarlyView.
A “liquid locking” strategy is proposed and implemented for scalable printing of crack‐free bassanite ceramic frameworks with interlocking microstructures to host ionic liquids as effective electrolytes for high‐temperature micro‐supercapacitors (HT‐MSCs).

On Distinguishing Non-Standard Interactions from Radiative Corrections in Neutrino-Electron Scattering

open access: yes, 2003
We present a contribution of higher order to neutrino-electron scattering that is a charged-current counterpart of both the anomalous axial-vector triangle and possible non-standard interaction contributions.

Choline Ionic Liquid for Long‐Term Stable Organic Electrochemical Transistors

open access: yesAdvanced Materials, EarlyView.
Choline‐based ionic liquid integrated organic electrochemical transistors (Chol‐OECTs) for improvement of performance and prolonged lifetime is demonstrated. Introduction of the ionic liquid into PEDOT:PSS and gelatin creates choline acetate ionic liquid‐infused PEDOT:PSS (CLiPS) and choline acetate‐gelatin (CAGel) electrolyte.

How Relevant Are Non-Use Values and Perceptions in Economic Valuations? The Case of Hydropower Plants

open access: yesEnergies, 2019
The construction of hydropower plants, particularly of large ones, is far from being a consensual decision: advocates defend their construction based on the unquestionable benefits hydropower provides, while critics argue that these facilities are far ...
