Placa de ateroma da bifurcacao carotidea: como identificar a lesao "activa"?

The identification of carotid atheromatous plaques associated to a higher neurologic risk may be important in therapeutic decision making for asymptomatic patients and symptomatic patients with 50%-70% stenosis. The introduction of high-definition ultrasonography (HDU) and computer-assisted image analysis provides the possibility of a standard, objective and detailed characterization of the struct

Analysis of the interaction of Aeromonas caviae, A. hydrophila and A. sobria with mucins

Aeromonas species are known to be involved in human gastrointestinal diseases. These organisms colonize the gastrointestinal tract. Aeromonas hydrophila, A. caviae, and A. sobria have been demonstrated microscopically to adhere to animal cell lines that express mucous receptors, but quantitative studies of adherence to mucosal components such as mucin have not been published to date. Purified bovi

Heart Failure Management in the Elderly. Focus on Health Economics and Quality of Life

The incidence and prevalence of heart failure (HF) has increased successively over the past decade. Mortality and morbidity is high. It is the most common cause of hospitalisation in the elderly and has been estimated to account for 1-3% of health care costs in many countries. There is a need therefore, to improve care for HF patients. However, due to limited economic resources, this must be done

Improved Scheduling of Control Tasks

The paper considers the implementation of digital controllers as real-time tasks in priority-preemptive systems. The performance of a digital feedback control system depends critically on the timing of its sampling and control actions. It is desirable to minimize the computational delay in the controller, as well as the sampling jitter and the control jitter. It is shown that by scheduling the two

fMRI activation mapping using wavelet-based SPM (WSPM) integrated with gray-matter graphs

In many fMRI task-evoked studies, localized brain activity can be detected by GLM fitting and statistical hypothesis testing. Statistical parametric mapping (SPM) is the classical method that requires Gaussian pre-smoothing of the data. Instead, the wavelet transform provides a compact representation of activation patterns. Wavelet based SPM (WSPM) is an extension of SPM that combines wavelet proc

Self-Identification and Self-Reference

Wittgenstein once made a distinction between two uses of "I". The first use, as object, as in "I have broken my arm" or "The wind is blowing in my hair", involves the recognition of a particular person, and there is the possibility of error concerning the identity of the person. In the other use, as subject, as in "I think it will rain" or "I am trying to lift my arm", no person is recognised. No

A Compressed Depth Cache

We propose a depth cache that keeps the depth data in compressed format, when possible. Compared to previous work, this requires a more flexible cache implementation, where a tile may occupy a variable number of cache lines depending on whether it can be compressed or not. The advantage of this is that the effective cache size increases proportionally to the compression ratio. We show that the dep
