Frequent itemset mining is a popular and important first step in the analysis of data arising in a broad range of applications. The traditional " exact " model for frequent itemsets requires that every item occurs in each supporting transaction. Real data is typically subject to noise and measurement error. To date, the effects of noise on exact frequent(More)
Frequent itemset mining is a popular and important first step in analyzing data sets across a broad range of applications. The traditional, " exact " approach for finding frequent itemsets requires that every item in the itemset occurs in each supporting transaction. However, real data is typically subject to noise, and in the presence of such noise,(More)
OBJECTIVE Active or passive immunisation can mitigate plaque pathology in murine models of Alzheimer's disease (AD). Recently, it has been shown that antibodies against beta-amyloid (Abeta) are present in human immunoglobulin preparations (IVIgG), which specifically recognise and inhibit the neurotoxic effects of Abeta. This study reports the results from a(More)
As part of a research project, a behavior therapy-oriented cognitive training program, designed to improve the cognitive ability of middle-aged employees (50 to 59 years), was implemented and evaluated. The goal of the training program was to analyze the cognitive, affective and behavior-related conditions of memory deficits in the workplace. The training(More)
OBJECTIVE To determine faculty perceptions about an evidence-based peer teaching assessment system. METHODS Faculty members who served as instructors and assessors completed questionnaires after year 1 (2002-2003) and year 4 (2005-2006) of the peer assessment program. Factors were evaluated using a Likert scale (1 = strongly disagree; 5 = strongly agree)(More)
Due to aging of the population and a possible rise in retirement age, the cognitive capacity of older people is gaining great importance. As evidenced by the increase in early retirement due to psychosomatic disease, many employees are not capable of working at a higher age. Decreasing cognitive abilities have usually been studied in subjects over 65 years(More)
It is shown from molecular statistical considerations that a demixing instability exists in the moment space of a microbial protein expression profile. Although avoidance of demixing is generally requisite for biological function, a comparison with proteomic and genomic data suggests that many microbes lie close to the onset of this instability. Over(More)
