An Independent Component Analysis Based Tool for Exploring Functional Connections in the Brain [PDF]

, 2007
This thesis describes the use of independent component analysis (ICA) as a measure of voxel similarity, which allows the user to find and view statistically independent maps of correlated voxel activity. The tool developed in this work uses a specialized

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

VIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.

CW_ICA: an efficient dimensionality determination method for independent component analysis

Scientific Reports
Independent component analysis (ICA) is a widely used blind source separation method for signal pre-processing. The determination of the number of independent components (ICs) is crucial for achieving optimal performance, as an incorrect choice can ...

Speech Recognition Deficits in Presbyacusis: Links to Cortical Structural and Functional Alterations

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To characterize speech recognition in presbyacusis and its associated neurophysiological and cortical structural features, and to explore structure‐function‐behavior relationships within the presbyacusis phenotype. Methods Thirty elderly patients with presbyacusis(HI) and thirty‐three healthy young controls(NH) completed a behavioral

Climate exposure drives firm political behavior: Evidence from earnings calls and lobbying data

American Journal of Political Science, EarlyView.
Abstract When and how do firms engage in climate politics? We argue that regulatory concerns, business opportunities, and physical risks activate policy preferences and lobbying efforts. We measure firm‐level exposure to opportunity, regulatory, and physical aspects of climate change based on discussion in quarterly earnings call transcripts for 11,705
