Decision fusion for the classification of hyperspectral data: outcome of the 2008 GRS-S Data Fusion Contest
The 2008 Data Fusion Contest organized by the IEEE Geoscience and Remote Sensing Data Fusion Technical Committee deals with the classification of high-resolution hyperspectral data from an urban area. Unlike in the previous ...
IR-UWB radar demonstrator for ultra-fine movement detection and vital-sign monitoring
In this paper an impulse-radio ultra-wideband (IR-UWB) hardware demonstrator is presented, which can be used as a radar sensor for highly precise object tracking and breath-rate sensing. The hardware consists of an impulse ...
PKCalpha is genetically linked to memory capacity in healthy subjects and to risk for posttraumatic stress disorder in genocide survivors
Strong memory of a traumatic event is thought to contribute to the development and symptoms of posttraumatic stress disorder.
Age-related changes in neural functional connectivity and its behavioral relevance
Background: Resting-state recordings are characterized by widely distributed networks of coherent brain activations. Disturbances of the default network - a set of regions that are deactivated by cognitive tasks and activated ...
Plasmonic titania photocatalysts active under UV and visible light irradiation: influence of gold amount, size and shape
Plasmonic titania photocatalysts were prepared by titania modification with gold by photodeposition. Photodeposition method was found to be profitable since during only 15 minutes of irradiation the complete gold precursor ...
A 60 to 77 GHz switchable LNA in an RF-MEMS embedded BiCMOS technology
In this letter, a 60 to 77 GHz switchable low-noise amplifier is presented. The IC is realized in a radio frequency microelectro-mechanical systems embedded 0.25 µm SiGe-C BiCMOS technology. Measured results show that the ...
Multi-Gb/s analog synchronous QPSK demodulator with phase-noise suppression
In this paper, an IF quadrature phase-shift keying demodulator is presented, which performs phase and frequency synchronization in the analog domain. The presented demodulator can be utilized for short-range ultra-wideband ...
This article presented the possibilities of making microwave and mm-wave ICs more intelligent through a combination of established Si/SiGe BiCMOS technologies, which allow for complex ICs combining a multitude of high-speed ...
Changes in cortical slow wave activity in healthy aging
Enhanced slow wave activity has been found in stroke patients, schizophrenia, depression, Alzheimer´s disease and post-traumatic stress disorder, but the relationship between slow wave activity and healthy aging is as yet ...
Spreading of amyloid, tau, and microvascular pathology in Alzheimer´s disease: findings from neuropathological and neuroimaging studies
Primary pathologies including amyloid-beta (Abeta) plaques and neurofibrillary tangles (NFT) develop many years before the onset of dementia symptoms in Alzheimer’s disease (AD). Age-related small vessel disease (SVD) is ...
