—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)
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)
The balance between stem cell self-renewal and differentiation is controlled by intrinsic factors and niche signals. In the Drosophila melanogaster ovary, some intrinsic factors promote germline stem cell (GSC) self-renewal, whereas others stimulate differentiation. However, it remains poorly understood how the balance between self-renewal and(More)
Mutations in the sequestosome 1 gene (SQSTM1) have recently been identified in patients with amyotrophic lateral sclerosis, accounting for 1.11%-4.92% of familial ALS and 2.42%-4.37% of sporadic amyotrophic lateral sclerosis (SALS). The mutation spectrum of SQSTM1 in Chinese patients with SALS remains unknown. Three hundred and six patients with SALS from(More)
Glial fibrillary acidic protein (GFAP) is an intermediate filament protein that is highly expressed in reactive astrocytes. Increased production of GFAP is a hallmark of astrogliosis in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). However, the physiological and pathological roles of GFAP, particularly in chronic neurodegenerative(More)
Sequential computations can benefit from a distributed environment consisting of a network of workstations through the use of a mobile agent system. We found significant performance improvement when sequential algorithms for solving large industrial problems are implemented using mobile agents. This is because raw data is distributed so that the cost of(More)
