Phase shifts in high-beta- and low-gamma-band local field potentials predict the focus of visual spatial attention.The local field potential (LFP) contains rich information about activity in local neuronal populations. However, it has ... VL Mock,KL Luke,JR Hembrook-Short,... - 《Journal ...
利用空矩阵(Ⅱ]得到[low_in high_in]或[low_out high_out],将导致结果都默认为[01]。如果high_out小于low_out,输出灰度将反转。 参数gamma指明了由f映射生成图像g时曲线的形状。如果gamma的值小于1,映射被加权至较高(较亮)的输出值,如图2-2(a)所示。如果gamma的值大于1,映射加权至较低(较暗)的输出值。
25–50 Hz, broadband high-gamma activity: BHA, 80–150 Hz)53. Despite these precautions, we cannot expect that the theta/beta and low-beta/gamma phase-amplitude CFCs to be fully represented due to the limited bandwidth we can afford for the modulated frequency. The band-pass filter wa...
通过对该井泥浆侵入分析,3 960～4 000 m地层在泥浆中浸泡后,复测电阻率P40H明显低于随钻电阻率P40H,复测电阻率A40H与随钻电阻率A40H无差异(图2),指示地层受到泥浆侵入明显,泥浆侵入深度大于P40H探测深度,小于A40H探测深度(地层电阻率为30 Ωm时,A40H径向探测深度为62 in(约157 cm),P40H径向探测深度为35 ...
Neural frequency bands were isolated from raw LFP using band-pass filtering (delta: 1–4 Hz, theta: 4–8 Hz, alpha: 8–13 Hz, beta: 13–30 Hz, low gamma: 35–55 Hz, high gamma: 65–120 Hz), and power spectral density was computed in baseline and post-injection conditions for ...
Parametrisation of F_2^gamma at low Q^2 and of sigma(gamma,gamma) and sigma(gamma^*,gamma) at high energies A parametrisation of the real photon structure function F_2^gamma in the low Q^2, low x region is formulated. It includes both the VMD and the QCD componen... B Badelek,...

We include among them light-tail distributions, such as the exponential (EXP), the normal (NRM) or the gamma (GAM) distributions; and long-tail (heavy-tail) distributions, such as the Log-Normal (LN) and Generalized Pareto (GPa) distributions. Some of them are more general distributions, ...
In fetuses and infants, beta chains are not common and the hemoglobin molecule is made up of two alpha chains and two gamma chains. As the infant grows, the gamma chains are gradually replaced by beta chains, forming the adult hemoglobin structure. Each globulin chain contains an important iro...
