Downlink calibration requirements for the TSUNAMI (II) adaptive antenna testbed [PDF]
The TSUNAMI (II) project is an investigation into the use of adaptive antenna technology. The field trial system has been developed for the purposes of investigating the feasibility of implementing such a system using a GSM-1800 base station system.

A robust adaptive beamformer based on the support vector machines is proposed to solve the rapid degradation of the performance of minimum variance distortionless response beamformer when the steering vector is mismatched. The proposed beamformer assumes

Uncertainty is typically linked to the need for cognitive control reflected in greater theta band activity. We manipulate uncertainty as a trigger for curiosity in a spatial cueing paradigm. Time–frequency and DICS beamforming results show that uncertainty is not always linked to greater theta band activity.

Impact of a moving noise masker on speech perception in cochlear implant users.
ObjectivesPrevious studies investigating speech perception in noise have typically been conducted with static masker positions. The aim of this study was to investigate the effect of spatial separation of source and masker (spatial release from masking ...

The Mismatch Negativity Compared: EEG, SQUID‐MEG, and Novel 4Helium‐OPMs
In this study, we compared the mismatch negativity (MMN), evoked by an auditory oddball paradigm, between EEG, cryogenic SQUID‐MEG, and a novel prototype Helium‐OPM system. Results show high similarity in the evoked time courses and signal‐to‐noise ratios, showing potential for reliable application of OPM‐MEG in MMN research, including routine clinical

Central Pathophysiology and Brain Network Changes Related to Camptocormia in Parkinson's Disease
ABSTRACT Background Studies on brain connectivity offer important insights into the changes that occur in central network diseases such as Parkinson's disease (PD). Camptocormia, a condition characterized by abnormal flexion of the trunk, often occurs in advanced PD, but its underlying mechanisms are not yet clear.

This study examined periodic and aperiodic EEG activity in schizophrenia spectrum disorder (SSD) using FOOOF across scalp and source‐level recordings. SSD patients showed increased theta power and aperiodic components, with dACC theta predicting cognitive impairment. Findings highlight altered excitation–inhibition dynamics and emphasize the utility of
