The charge transfer efficiency of a CCD is based on the average level of signal lost per pixel over a number of transfers. This value can be used to directly compare the relative performances of different structures, increases in radiation damage or to quantify improvements in operating parameters. This number does not however give sufficient detail to(More)
We are developing algorithms for semi-automated simplification of medical text. Based on lexical and grammatical corpus analysis, we identified a new metric, term familiarity, to help estimate text difficulty. We developed an algorithm that uses term familiarity to identify difficult text and select easier alternatives from lexical resources such as(More)
Measuring text difficulty is prevalent in health informatics since it is useful for information personalization and optimization. Unfortunately, it is uncertain how best to compute difficulty so that it relates to reader understanding. We aim to create computational, evidence-based metrics of perceived and actual text difficulty. We start with a corpus(More)
OBJECTIVE To assess whether hearing aids improve the quality of life of elderly persons with hearing loss. SETTING Primary care clinics at a Bureau of Veterans Affairs hospital. PATIENTS One hundred and ninety-four elderly veterans who were identified as being hearing impaired from a screening survey involving 771 consecutive clinic patients. Of the(More)
Hearing impairment is one of the most common chronic health problems of elderly Americans. Although adverse effects on quality of life are thought to be considerable, they have not been rigorously evaluated. This study was designed to identify the types and extent of dysfunction experienced by elderly individuals with hearing loss, and to define the most(More)
The Schizosaccharomyces pombe cell cycle-regulatory protein suc1, named as the suppressor of cdc2 temperature-sensitive mutations, is essential for cell cycle progression. To understand suc1 structure-function relationships and to help resolve conflicting interpretations of suc1 function based on genetic studies of suc1 and its functional homologs in both(More)
BACKGROUND Adequate health literacy is important for people to maintain good health and manage diseases and injuries. Educational text, either retrieved from the Internet or provided by a doctor's office, is a popular method to communicate health-related information. Unfortunately, it is difficult to write text that is easy to understand, and existing(More)
With increasing text digitization, digital libraries can personalize materials for individuals with different education levels and language skills. To this end, documents need meta-information describing their difficulty level. Previous attempts at such labeling used readability formulas but the formulas have not been validated with modern texts and their(More)
