虽然这个较差的时间分辨率是fMRI与生俱来的,但我们仍然发展出了一些解决办法。 其中之一就是时间超敏度(Temporal hyperacuity)的方法,它的一种做法是将同一种事件都进行平均,那么我们就能够以100-200msec的延迟来检测到平均反应的差异。这种方法的出现得益于快速采样方法的出现,能够在100-200msec内得到整个大脑的图像。
a formal theory of spatial and temporal resolution of observations underlying geographic information. The theory has a dual importance: (i) at the theoretical level, it is to be taken as a small and necessary piece of the science of scale; (ii) at the practical level, the axioms of the t...

locations with fire activity associated with specific meteorological conditions that are not appreciable at the monthly temporal resolution, are probably not well identified. For example, a week of extremely high temperatures could be almost unnoticeable in the monthly mean temperature, but not in fire...

Understanding spatiotemporal variation in environmental conditions is important to determine how climate change will impact ecological communities. The spatial and temporal autocorrelation of temperature can have strong impacts on community structure and
9.1.2.4Temporal resolution Temporal resolution is the measure of frequency or repeat cycle where the sensor returns to the same part of Earth’s surface. Here, the characteristics of frequency are obtained by the satellite sensor and their orbit pattern. The frequency of the flyovers by plane or...
2.1. Meteorological and PM2.5 observation data Visibility, relative humidity and weather phenomena data were obtained from conventional ground meteorological observation dataset, with temporal resolution of 3 h from more than 2000 stations (Fig. 1). To exclude possible errors caused by observation of ...
datasets to 8-day temporal resolution and 0.05° spatial resolution, respectively. Then, the arithmetic mean values of the LAI datasets were calculated as the input of the PT-JPL model. Meteorological inputs. Meteorological forcing data such as net radiation, mean air temperature, and relative ...
