De et al. 1 focus their study on cells that can be approximated to first order as contractile force dipoles in which the cell axis z is oriented at an angle θ with respect to the direction of an ...

In a 2014 study published in Nature, scientists in Australia, India, China and Japan modelled the effects of CO2 on extreme Indian Ocean dipoles, such as those in 1961, 1994 and 1997. Assuming ...

研究者在一种参与脂肪醛氧化的酶附近发现了一种假定的因果变异，并在酵母中测试了这种基因，以确认其产生色素变化的能力。研究中广泛的生化和遗传学工作有助于人们了解非模式生物的颜色，为未来对鹦鹉和其他鸟类色素沉着的研究打开大门。

As far as hobbies go, ham radio tends to be on the more expensive side. A dual-band mobile radio can easily run $600, and a ...

Ideally, if you are going to transmit, you want a properly-tuned resonant antenna. But, sometimes, it isn’t practical. [Ham Radio Rookie] knew about random wire antennas but didn’t want a wire ...

An introduction to properties of individual antennas and arrays of antennas. Retarded potentials, dipoles of arbitrary length, radiation pattern, gain, directivity, radiation resistance. The loop ...

The components that go into the latest antennas have become reliant on the latest innovations… from using ceramic, rather ...

This contrasts with the much more commonly used magnetic dipoles, which have two poles and resemble tiny bar magnets. Using ...

Researchers have developed a way to produce static electricity from motion and wind. The invention made from waste polystyrene by RMIT University in collaboration with Riga Technical University in ...
