This paper proposes a CDE-MPR methodology designed to forecast and analyze container throughput volumes. The proposed methodology includes: a container throughput module which considers both interactions among ports and other influence factors, a demand demand-oriented module which provides additional information and chance events effect had on the maritime industries. It is applied to forecast...
Despite implications for carcinogenesis and other chronic diseases, basic mechanisms of p53 and its variants in suppressing Bcl-2 levels are poorly understood. Bcl-2 sustains mucous cell metaplasia, whereas p53(-/-) mice display chronically increased mucous cells. Here we show that p53 decreases bcl-2 mRNA half-life by interacting with the 5' untranslated region (UTR). The p53-bcl-2 mRNA intera...
The Drosophila pair-rule gene paired is required for the correct expression of the segment polarity genes wingless, engrailed and gooseberry. It encodes a protein containing three conserved motifs: a homeodomain (HD), a paired domain (PD) and a PRD (His/Pro) repeat. We use a rescue assay in which paired (or a mutated version of paired in which the functions of the conserved motifs have been alt...
Although the cities in Pearl River Delta (PRD) China are amongst world’s most exposed to flooding due climate change, surprisingly little is done address this problem. This article explores barriers emergence of policies adapting growing flood risk two PRD cities, Guangzhou and Shenzhen, underlining importance Chinese territorial governance system for adaptive capacity at local level. Focusing ...
Increasing numbers of patients with different types of dementia have resulted in the increasing medical care loads. It is not known whether explanatory factors for recurrent or prolong hospitalization were driven by the subtypes of dementia. We analyzed 203 dementia patients aged >65-year-old with a clinical diagnosis of Alzheimer disease (AD), vascular dementia (VaD), or Parkinsonism-related d...
A new hybrid two-stage electrocardiogram (ECG) signal compression method based on the modified discrete cosine transform (MDCT) and discrete wavelet transform (DWT) is proposed. The ECG signal is partitioned into blocks and the MDCT is applied to each block to decorrelate the spectral information. Then, the DWT is applied to the resulting MDCT coefficients. Removing spectral redundancy is achie...
The data on the heavy metal content at different soil depths derived from a multi-purpose regional geochemical survey in the Pearl River Delta (PRD) were analyzed using ArcGIS 10.0. By comparing their spatial distributions and areas, the sources of heavy metals (Cd, Hg, As and Pb) were quantitatively identified and explored. Netted measuring points at 25 ×25 km were set over the entire PRD acco...
The ancient origin of sleep is evidenced by deeply conserved signaling pathways regulating sleep-like behavior, such as signaling through the Epidermal growth factor receptor (EGFR). In Caenorhabditis elegans, a sleep-like state can be induced at any time during development or adulthood through conditional expression of LIN-3/EGF. The behavioral response to EGF is mediated by EGFR activity with...
The immune receptor signaling pathway is used by nonimmune cells, but the molecular adaptations that underlie its functional diversification are not known. Circulating platelets use the immune receptor homologue glycoprotein VI (GPVI) to respond to collagen exposed at sites of vessel injury. In contrast to immune cell responses, platelet activation must take place within seconds to successfully...
Phytochromes are red and far-red photoreceptors that regulate plant growth and development in response to environmental light cues. Phytochromes exist in two photo-interconvertible conformational states: an inactive Pr form and an active Pfr form. The alteration of phytochromes' subcellular location functions as a major regulatory mechanism of their biological activities. Whereas phytochromes i...
