Firstly, the paper, combining the characteristic of synchronous pulse bursts and inhibition with the modified pcnn model, presents a way of finding the foveation points in the images adaptively and effectively, and simulates the human vision system. secondly, pcnn is extended to pcnns, based on the properties of information couple and transmission, an algorithm that is used to fuse images of the same target got by several sensors to an image is presented to simulate the human vision system. thirdly, combining the properties of synchronous pulse bursts, capture, and transmission and competition of waves, the paper presents two ways of classification, one is an algorithm based on the properties of neuron to capture and inhibit to classify the data taking on any complex unlinear distribution robustly, the other is based on the restricted distance and modified of the former to remove the influence of inferior samples in classification ; fin ally, based on the accumulative difference pictures, and the forming and transmission of pcnn wave, selecting and controlling the direction of autowave by connecting the neighbouring neurons selectively, the paper presents a way to simulate the tracks of moving object and detect the moving direction
首先結合pcnn的同步脈沖發放和側抑制特性，提出了基於改進型pcnn的圖像凹點檢測演算法，該演算法是一種自適應而有效的圖像凹點檢測方法，並且較好地模擬了人類視覺系統；然後，結合信息傳遞和信息耦合特性，將pcnn擴展成pcnns （ pcnn網路群） ，提出了一種基於pcnns的圖像融合演算法，能夠將多個傳感器獲取的同一目標的圖像信息融合到一幅圖像中，有效模擬了人類視覺系統；另外，結合pcnn的同步脈沖發放特性、捕獲特性和波的傳播競爭特性，開拓地將pcnn用於模式分類中，提出了基於耦合神經元點火捕獲抑制特性的分類方法和改進的約束距離下的pcnn分類方法，前者可實現對樣本空間中任意復雜分佈訓練樣本的穩健非線性分類，而後者能夠消除訓練樣本中刺點對分類的影響；最後，結合累積差分圖像思想、 pcnn波的形成與傳播特性，通過各神經元之間連接取向來選擇與控制自動波的流向，將pcnn用於運動視覺分析中的運動軌跡模擬及運動方向檢測。In this paper the methods of chronically implanting microelectrodes, combined electrophysiology with behavioral learning in vivo, were used to study the effects of low frequency stimulation ( lfs ) of the dorsal norepinephrine bundle ( dneb ) on the learning - dependent long - term potentiation ( ld - ltp ) at the hippocampal mossy fiber synapses onto ca3 pyramidal neurons. paired - pulse technique at the intervals of 75 - ms, 150 - ms and 300 - ms was used as the test stimulation. the results showed as follows : 1

本研究的目的是要從理論上探討利用單電極雙向脈沖刺激實現哺乳動物神經纖維選擇性刺激， （即當刺激一束神經時，不興奮粗神經而興奮細神經）的可能性.雙向脈沖刺激可以降低刺激脈沖對神經纖維產生的電化學損傷.為研究哺乳動物有髓神經纖維的電特性，建立了一個基於簡單的無窮大、各向同性的容積導體模型的模擬系統.利用該模擬系統，採用「不對稱但電荷平衡」的雙向脈沖刺激，計算了神經纖維的興奮和阻斷閾值與纖維直徑、纖維-電極間距離的關系.結果表明：在距電極一定距離內採用該雙向脈沖刺激模式確實可以實現哺乳動物有髓神經纖維的選擇性興奮Under the influence of the submergence the turbulence intensity are quite high at the end stage of burning. however, the turbulence intensity decreases obviously at the medium stage and the preliminary stage of burning because the flow disturbance is eliminated by the mixture of injection flow and main flow

比較氧療開始或結束、睡前和睡眠期間、活動前和活動時、及抽吸分泌物后的動脈血氧飽和度。Exercise could lead to remodeling of icn, of which normal exercise load might lead to proportional increase of cardiac and icn, adapting oneself ot transmit of contractility between myocardial bundles and cardiac muscle cell ( cmc ) under conditions of myocardial hypertrophy ; and exercise overload might lead to increase of a large number of different collagen among myocardial bundles, cmc, arteriole and capillary, that could lead to increase of stiffness and descent of systolic and diastolic function of heart
運動可引起心肌間質膠原網路結構的重塑，一般運動負荷可使心肌與間質膠原網路同步增長，以適應心肌細胞肥大收縮力增加從而保證肌束間及心肌細胞間力的傳遞；運動超負荷可使心肌束間、心肌細胞間以及小動脈和毛細血管間不同類型膠原大量蓄積增生，導致心臟的僵硬度增加，舒縮功能降低。分享友人
