This paper presents a novel method for estimating a spectral reflectance from two kinds of input images: an image including both visible light components and near-infrared (NIR) components, and an image including only NIR components. From these input images, we estimate the spectral reflectance based on the Non-negative Matrix Factorization algorithm using(More)
Polysilsesquioxane (PSQ) liquids have been prepared from propyltrimethoxysilane-water and trimethoxy(3-sulfanylpropyl)silane-water binary systems without the use of organic solvents through hydrolytic polycondensation followed by aging. By introducing the aging step, the viscosity of the as-prepared PSQ liquid is decreased by more than an order of(More)
AIM Not only cardiovascular disease (CVD) itself, but also subclinical major electrocardiographic (ECG) abnormalities are related to frailty in older adults. We investigated whether major ECG abnormality was associated with first support/care-need certification in Long-Term Care Insurance or death in community-dwelling older adults. METHODS We analyzed(More)
