PURPOSE Are eccentric hamstring strength and between-limb imbalance in eccentric strength, measured during the Nordic hamstring exercise, risk factors for hamstring strain injury (HSI)? METHODS Elite Australian footballers (n = 210) from five different teams participated. Eccentric hamstring strength during the Nordic exercise was obtained at the commencement and conclusion of preseason train...

The paper presents a comparative political economy theoretical framework of high-skilled immigration (HSI thereafter) policies in advanced industrial countries and seeks to explain differences in countries’ policies in terms of HSI openness. I take from the traditional partisanship approach that political parties will pursue policies consistent with the preferences of their major constituencies...

Heterosubtypic immunity (HSI), defined as protective cross-reactivity to lethal infection with influenza A virus of a serotype different from the virus initially encountered, is thought to be mediated by cross-reactive cytotoxic T lymphocytes (CTL). This study provides direct evidence for the role of effector CTL versus B cells in HSI in mice with a targeted disruption in the alpha chain of CD8...

BACKGROUND The disease burden due to heat-stress illness (HSI), which can result in significant morbidity and mortality, is expected to increase as the climate continues to warm. In the United States (U.S.) much of what is known about HSI epidemiology is from analyses of urban heat waves. There is limited research addressing whether HSI hospitalization risk varies between urban and rural areas,...

Habitat suitability index (HSI) models provide spatially explicit information on the capacity of a given habitat to support a species of interest, 2 and their prevalence has increased dramatically in recent years. Despite caution that the reliability of HSIs must be validated using independent, 4 quantitative data, most HSIs intended to inform terrestrial and marine species management remain un...

Most hyperspectral images (HSI) have important spectral features in specific combination of wave numbers or channels. Noise in these specific channels or bands can easily overwhelm these relevant spectral features. Maximum Noise Fraction (MNF) by Green et al. [1] has been extensively studied for noise removal in HSI data. The MNF transform maximizes the Signal to Noise Ratio (SNR) in feature sp...

With the development of deep learning, the performance of hyperspectral image (HSI) classification has been greatly improved in recent years. The shortage of training samples has become a bottleneck for further improvement of performance. In this paper, we propose a novel convolutional neural network framework for the characteristics of hyperspectral image data, called HSI-CNN. Firstly, the spe...

Hyperspectral image (HSI) denoising is essential for enhancing HSI quality and facilitating HSI processing tasks. However, the reduction of noise in HSI is a difficult work, primarily due to the fact that HSI consists much more spectral bands than other remote sensing images. Therefore, comparing with other image denoising jobs that rely primarily on spatial information, efficient HSI denoising...

We present a habitat suitability index (HSI) model for black bears (Ursus americanus) living in the southern Appalachians that was developed a priori from the literature, then tested using location and home range data collected in the Pisgah Bear Sanctuary, North Carolina, over a 12-year period. The HSI was developed and initially tested using habitat nd bear data collected over 2 years in the ...

The ability of hyperspectral image (HSI) data to provide estimates of soil electrical conductivity (ECa) and soil fertility levels without requiring extensive field data collection was investigated. The relationships between HSI spectral reflectance signatures and soil properties were analyzed to evaluate the usefulness of HSI for quantifying within -field spatial variability. Bare soil images ...
