OBJECTIVE Gliomas are the most common type of primary intracranial tumor. Although tumor grade predicts the clinical course of most patients, molecular characteristics of individual tumors have emerged as important prognostic factors for patients with gliomas. Reduced expression of p27 protein is known as an independent prognostic marker in a large variety(More)
Forkhead box class O 3a (FOXO3a) is an important direct target of the phosphatidylinositol 3-kinase (PI3K)/protein B(Akt) pathway, mediating signal transduction in regulating cell survival and cell-cycle progression. Recent reports have shown that FOXO3a inhibits cell-cycle progression at the G1/S transition by controlling transcription of the(More)
The role of CDX2 in trophectoderm (TE) cells has been extensively studied, yet the results are contradictory and species specific. Here, CDX2 expression and function were explored in early porcine embryos. Notably, siRNA-mediated gene knockdown and lentivirus-mediated TE-specific gene regulation demonstrated that CDX2 is essential for the maintenance of(More)
A phased array is presented to extend array scanning range by using pattern reconfigurable patch antenna elements in this paper. The antenna structure consists of a driven element surrounded by four parasitic elements that act either as reflector or director depending on the switching arrangement. Beam reconfiguration is achieved by using four p-i-n diode(More)
A benign lymphoepithelial lesion (BLEL) is an idiopathic inflammation of the parotid gland, characterized by hyperplasia, lymphocyte infiltration and the formation of epimyoepithelial islands, as well as atrophy of the gland parenchyma. Common treatment methods include immunosup-pression and glucocorticoid therapies, in addition to surgical dissections.(More)
Data analysis is receiving considerable attention with the design of new graphics processing units (GPUs). Our study focuses on geostatistical data analysis, which is currently applied in diverse disciplines such as meteorology, oceanography, geography, forestry, environmental control, and agriculture. While geostatistical analysis algorithms are applied in(More)
Runtime system-level power estimation is essential for dynamic power adaptation in integrated circuits. Indirect power estimation using a CPU performance monitoring unit (PMU) is widely used in modern microprocessors for its low cost. However, the existing CPU PMUs only monitor the activities of core and cache, resulting in accuracy limitation in power(More)
With the development of manufacturing technology and increasing complexity of functionality, traditional IC design method has become difficult to meet the demands of limited time-to-market and researchers' interests have been concentrated on novel design methods such as high-level synthesis, in which operator design method is one of the most promising(More)
A hybrid method combining artificial neural network (ANN) with genetic algorithm (GA) is discussed in this paper. A new strategy of optimization on ANN structure and weights based on multi-population GA is proposed, and the quantitative optimization of ANN is realized. The Levenberg-Marquardt(LM) algorithm is used for further training the neural network,(More)
