The frequency,f,of the oscillation is the number of cycles which occur in a given unit of time ;the customary unit is cycles per second,cps,or hertz,Hz,It should be noted that the frequency is the reciprocal of the period,or,in equation form,f=1/T 震动的频率,f,是单位时间内所做的循...
one second. b. the number of cycles or completed alternations per unit time of a wave or oscillation. Symbol: F; Abbr.: freq. 4. Math. the number of times a value recurs in a unit change of the independent variable of a given function. 5. Statistics. the number of items ...
The Cortex-M3 RTL is delivered to licensees together with an "example" system testbench for simulation of a simple Cortex-M3 system, and a number of test programs including a Dhrystone test called "dhry". This program reports the average number of processor clock cycles per loop of the Dhrys...
Inheritance and clearance of maternal mRNAs are two of the most critical events required for animal early embryonic development. However, the mechanisms regulating this process are still largely unknown. Here, we show that together with maternal mRNAs, C
Compared to proteins, glycans, and lipids, much less is known about RNAs on the cell surface. We develop a series of technologies to test for any nuclear-encoded RNAs that are stably attached to the cell surface and exposed to the extracellular space, he
The vertebrate brain emerged more than ~500 million years ago in common evolutionary ancestors. To systematically trace its cellular and molecular origins, we established a spatially resolved cell type atlas of the entire brain of the sea lamprey—a jawl
Radiotherapy (RT) is delivered for purposes of local control, but can also exert systemic effect on remote and non-irradiated tumor deposits, which is called abscopal effect. The view of RT as a simple local treatment has dramatically changed in recent years, and it is now widely accepted th...
