Purpose To determine if skin intrinsic fluorescence (SIF), a noninvasive measure of advanced glycation endproducts and oxidative stress in skin is associated with AMD. Methods SIF was measured with the SCOUT DS skin fluorescence spectrometer in a cross-sectional cohort study of 969 persons aged 68 to 102 years from the 1181 who participated in the 25-year follow-up examination in the Beaver D...

RATIONALE AND OBJECTIVES Subchondral insufficiency fractures (SIF), previously termed spontaneous osteonecrosis of the knee, are marked by a sudden onset of severe pain. Other than the size of the lesion, prediction for progression to joint replacement is difficult. The objective was to determine if quantitative analysis of bone texture using digital tomosynthesis imaging would be useful in pre...

We present a tool, called sif, for finding all similar files in a large file system. Files are considered similar if they have significant number of common pieces, even if they are very different otherwise. For example, one file may be contained, possibly with some changes, in another file, or a file may be a reorganization of another file. The running time for finding all groups of similar fil...

In this study, we evaluated chlorophyll fluorescence (CF) under two extreme 13 illumination conditions at plant scale with a passive spectroradiometer. Fluorescence (F) was 14 estimated by reading directly from radiance spectra of a variety of plants illuminated with 15 light-emitting diode (LED) grow lights in the laboratory. Solar-induced fluorescence (SIF) was 16 estimated from spectral meas...

Welded joints are prone to fatigue cracking with the existence of welding defects and bending stress. Fracture mechanics is a useful approach in which the fatigue life of the welded joint can be predicted. The key challenge of such predictions using fracture mechanics is how to accurately calculate the stress intensity factor (SIF). An empirical formula for calculating the SIF of welded joints ...

INTRODUCTION Cutaneous injection-related infections (CIRI) are a primary reason injection drug users (IDU) access the emergency department (ED). METHODOLOGY Using Cox proportional hazard regression, we examined predictors of ED use for CIRI, stratified by sex, among 1083 supervised injection facility (SIF) users. RESULTS Over a four-year period, 289 (27%) visited the ED for CIRI, yielding a...

Near-infrared (near-IR) excitation produces little background signal from biological molecules, making nearIR fluorescence technology highly useful in proteomic and genomic applications. To increase the emissions of near-IR fluorophores, we examined the use of metal-enhanced fluorescence on these longer wavelength dyes. IRDye700and IRDye800-labeled DNA oligonucleotides and proteins were spotted...

In the framework of the candidate EE-8 ESA/FLEX mission, different Solar-Induced Fluorescence (SIF) retrieval algorithms are under implementation and testing. The Spectral Fitting Method is the baseline for the fluorescence retrievals for FLEX, since it is a powerful technique to decouple canopy reflected radiance and SIF by exploiting the high-resolution observations in the red/far-red spectra...

SIF (Servlet Information Flow) is a novel software framework for building high-assurance web applications, using language-based information-flow control to enforce security. Explicit, end-to-end confidentiality and integrity policies can be given either as compile-time program annotations, or as run-time user requirements. Compile-time and run-time checking efficiently enforce these policies. I...

INTRODUCTION Correct choice of osteosynthesis method is a very important factor in providing the optimal conditions for appropriate healing of the fracture. There are still disagreements about the method of stabilization of some long bone fractures. Critically observed, no method of fracture fixation is ideal. Each osteosynthesis method has both advantages and weaknesses. OBJECTIVE The object...
