Comprehensive cellular responses was found in human amnion fl cells following exposure to low concentration of mnng, such as the lowering of dna replication fidelity resulted from alteration of dna polymerase profile ; activation of a lot of transcription factors, such as api, creb, nf - kb etc ; clustering of egfr ( epidermal growth factor receptor ) and tnfr ( tumor necrosis factor receptor ) and activation of camp - pka - creb and jnk / sapk signal pathways
我們發現，低劑量mnng處理后的人羊膜fl細胞有廣泛的細胞反應，並有多個信號轉導通路的激活和基因表達的改變。例如dna復制保真度下降， dna聚合酶譜發生改變，應用報告基因技術和底物磷酸化檢出技術證明細胞一系列轉錄因子如ap1 、 creb 、 nf b等被激活，細胞表面受體如表皮生長因子受體、腫瘤壞死因子受體發生聚簇，細胞信號轉導通路camp - pka - creb和jnk sapk被激活。 -

However, the paralleling communication can meet the requirements of high speed and fidelity in underwater signal transmissions. ofdm is a kind of novel paralleling transmission technology. the principle of ofdm is that the whole bandwidth can be divided into some subchannels, the high - speed serial signal stream is modulated by some orthogonal subcarriers
正交頻分復用（ ofdm ）是近年來數字通信中流行的一種并行傳輸新技術，其核心思想是將整個可用頻帶分割成多個正交子通道，將待傳輸的高速串列碼流并行的調制在這些子通道載波上。 -

Utilizing entanglement, we can implement the disembodied transport of an unknown quantum state from one place to another remote place with high - fidelity, i. e. quantum teleportation. via entanglement, we can also improve the channel capacity of classical signal in quantum channel, i. e. quantum dense coding, even we can entangle two quantum systems that have never directly interacted with each other by means of entanglement swapping
利用量子糾纏，通訊雙方可以實現對一個量子態的高保真度遠程傳輸，即量子離物傳態；利用量子糾纏，通訊雙方可以實現經典信息的高通道容量傳輸，即量子密集編碼；甚至可以使原本不糾纏的量子系統產生糾纏，即糾纏交換。 -
The underwater acoustic channel is very complex where cochannel interference, doppler frequency offsets, narrow bandwidth and time and frequency selective deep fades obstructs the development of high speed and fidelity underwater data transmissions. thus projects of high speed and fidelity underwater signal transmissions become a hotspot in the fields of world academic circles. the conventional serial communication must use adaptive equalizer to combat the multipath in real - time
海洋水聲通道是一種極其復雜多變的時-空-頻變參通道，其通道窄，強多途干擾，信號起伏衰落嚴重，一直是水下信息可靠高速傳輸的主要障礙，因此如何在水聲通道中高速率準確地傳輸數據，就成為世界性的熱門課題。 -

In order to assess the performance of the proposed methods, we propose three types of image measures to quantify the performance compared to some other methods. the first type evaluates the fidelity of the reconstructed image by computing the peak signal - to - noise ratio and euclidean distance in cielab color space between the original and reconstructed image in smooth and edge regions respectively. the second type accounts for a major artifact ? zipper effect
為了評估演算法質量，本文採用了三類評估手段:一是分別計算原始圖像與重構圖像在平滑區域與邊界區域的峰值信噪比與cielab顏色空間的歐氏距離來分析重構圖像的保真度;二是利用數學手段對重構圖像的一類主要失真現象? ? zipper效應進行定量評估;三是對硬體實現的成本與實際可行性進行了分析。 -
