BACKGROUND Among women who practice breast self-examination (BSE), breast cancers may be detected when they are at an earlier stage and are smaller than in women who do not practice BSE. However, the efficacy of breast self-examination for decreasing breast cancer mortality is unproven. This study was conducted to determine whether an intensive program of(More)
As the fast development of GPU, people tend to use it for more general purposes than its original graphic related work. The high parallel computation capabilities of GPU are welcomed by programmers who work at medical image processing which always have to deal with a large scale of voxel computation. The birth of NVIDIAreg CUDAtrade technology and(More)
—We propose a Smart Trend-Traversal (STT) protocol for RFID tag arbitration, which effectively reduces the collision overhead occurred in the arbitration process. STT, a Query Tree-based scheme, dynamically issues queries according to the online learned tag density and distribution; and therefore, it significantly reduces delay and energy consumption(More)
BACKGROUND Currently, several studies assessed the role of Tai Chi (TC) in management of chronic obstructive pulmonary disease, but these studies have wide variation of sample and convey inconclusive results. We therefore undertook a meta-analysis to assess the effects of TC. METHODS A computerized search through electronic databases was performed to(More)
Hydrogen peroxide (H(2)O(2)) plays important roles in plant biotic and abiotic stress responses. However, the effect of H(2)O(2) stress on the bread wheat transcriptome is still lacking. To investigate the cellular and metabolic responses triggered by H(2)O(2), we performed an mRNA tag analysis of wheat seedlings under 10 mM H(2)O(2) treatment for 6 hour in(More)
A Prioritized Medium Access Control (PMAC) protocol is proposed for wireless sensor networks, based on a binary count down approach. PMAC effectively eliminates data collision and optimizes channel allocation. Moreover, as many networks nowadays compose traffic with several priorities, the simple yet effective design of PMAC offers strict service(More)
This thesis explores three issues which are essential for economic development: poverty, risk and insurance. Risk, which is one of the causes and aspects of poverty, is the main issue investigated. The analyses are from a micro point of view and in the setting of rural areas in developing countries. It is found in the thesis that rural households in(More)
Amyotrophic lateral sclerosis (ALS) is a heterogeneous group of incurable motor neuron diseases (MNDs) characterized by a selective loss of upper and lower motor neurons in the brain and spinal cord. Most cases of ALS are sporadic, while approximately 5-10% cases are familial. More than 16 causative genes for ALS/MNDs have been identified and their(More)
OBJECTIVE To examine the associations of combined lifestyle factors and physical conditions with cerebrovascular diseases (CBVD) mortality, after accounting for competing risk events, including death from cardiovascular diseases, cancers and other diseases. METHODS Data on 2010 subjects aged over 55 years were finally analyzed using competing risk models.(More)
