Scalp‐negative medial temporal interictal epileptic discharges alter large‐scale brain networks: A simultaneous high‐density electroencephalographic and intracranial electroencephalographic study

Epilepsia, EarlyView.
Abstract Objective Interictal epileptiform discharges (IEDs) observed on scalp electroencephalography (EEG) serve as a diagnostic hallmark of epilepsy. However, only a small fraction of IEDs recorded by intracranial EEG (iEEG) are detectable on the scalp; the vast majority remain invisible on scalp recordings.

On the possibility of measuring relativistic gravitational effects with a LAGEOS-LAGEOS II-OPTIS-mission

, 2002
In this paper we wish to preliminary investigate if it would be possible to use the orbital data from the proposed OPTIS mission together with those from the existing geodetic passive SLR LAGEOS and LAGEOS II satellites in order to perform precise ...

Scalp fast oscillations detected by high‐density EEG as a noninvasive predictor of surgical outcome in temporal lobe epilepsy with hippocampal sclerosis

Epilepsia Open, EarlyView.
Abstract Objective To evaluate whether scalp oscillatory patterns—particularly scalp fast oscillations (SFOs) (>30 Hz) detected using 256‐channel high‐density EEG (HD‐EEG)—are associated with and can predict surgical outcomes in patients with drug‐resistant temporal lobe epilepsy with hippocampal sclerosis (TLE‐HS) undergoing anterior temporal ...

Measurements on the Absolute 2-D and 3-D Localization Accuracy of TerraSAR-X

Remote Sensing, 2018
The German TerraSAR-X radar satellites TSX-1 and TDX-1 are well-regarded for their unprecedented geolocation accuracy. However, to access their full potential, Synthetic Aperture Radar (SAR)-based location measurements have to be carefully corrected for ...

Experimental and Numerical Study on Enhancing the Performance of a Stepped Solar Still Using Porous Sponge Materials

Energy Science &Engineering, EarlyView.
Three designs were built and tested: a single‐slope still, a six‐stepped still, and a six‐stepped still with 5 mm sponge sheets. The novelty lies in fixing porous sponge sheets to the vertical faces of the steps. Yield of freshwater and instantaneous efficiency were determined in various combinations, that is, base, stepped, and stepped‐cum‐sponge ...

Infant frontal alpha asymmetry predicts social attention and transdiagnostic risk for emotional reactivity

JCPP Advances, EarlyView.
Abstract Background Differences in Frontal Alpha Asymmetry (FAA), derived from the electroencephalogram (EEG), have been associated with approach‐withdrawal behavior, although inconsistently. The current study examined how early patterns of FAA during the first 2 years of life relate to various socioemotional characteristics (at 2 years) and ultimately
