OBJECTIVE The objective was to evaluate the association of peripheral and central hearing abilities with cognitive function in older adults. METHODS Recruited from epidemiological studies of aging and cognition at the Rush Alzheimer's Disease Center, participants were a community-dwelling cohort of older adults (range 63-98 years) without diagnosis of dementia. The cohort contained roughly eq...

the nonlinear static procedures (nsps) proposed by design codes do not lead to reliable results especially for tall buildings. they generally provide inconsistent estimates of inelastic seismic demands, especially for the top floors due to their inabilities in considering the higher modes effects. in this paper, a new enhanced pushover procedure is proposed which is based on the envelope of the...

Linewidth roughness (LWR) remains a difficult challenge for improvement in resist materials. We intend to review work that focused on the impact of key components LWR by analyzing unbiased power spectral density (PSD) curves. studied systematic changes ArF formulations and correlated these overall PSD In this manner, we could extract 3σ values correlation length low/high-frequency components. a...

Species distribution, spatial distance, and neighboring interact6ions are among the most important drivers of global variation in plant species diversity. However, effects climate change on relationship between interactions diversity remain unknown. Here, we applied 12 machine learning models to assess responses spectral (indicating diversity) forests seven protected forest areas China. Changes...

          Spectral target detection could be regarded as one of the strategic applications of hyperspectral data analysis. The presence of targets in an area smaller than a pixel’s ground coverage has led to the development of spectral un-mixing methods to detect these types of targets. Usually, in the spectral un-mixing algorithms, the similar weights have been assumed for spectral bands. Howe...
