Bidirectional sampling gates allow signals to pass in both directions, enabling two-way communication, while unidirectional sampling gates permit signal flow in only one direction. This fundamental difference affects their applications; bidirectional gates are often used in scenarios requiring feedback or two-channel systems, whereas unidirectional gates are typically employed in simpler, one-way transmission systems. Additionally, bidirectional gates may introduce more complexity in design and control compared to their unidirectional counterparts.
Unidirectional TVS: A TVS device with asymmetrical current versus voltage (I−V) properties. A unidirectional TVS is best suited for protecting circuit nodes whose signals are unidirectional or always above or below the reference voltage, usually ground. Bidirectional TVS: A TVS device with symmetrical I−V properties. A bidirectional TVS is best suited for protecting electrical nodes whose signals are bidirectional or can have voltage levels both above and below the reference voltage, usually ground
Same, use bi if the gene products will be too big to resolve.
What is the difference between quota sampling and cluster sampling
a
Simple!
A bidirectional meter will meter power flowing in, and power flowing out separately. Unidirectional meters usually measure power (so flowing in will be added to power flowing out). If you're selling power and using power, you need to know how much you are producing (power flowing out), and how much power you are consuming (power flowing in) for correct billing.
sample is a noun and sampling is TO sample(verb)
The difference between convenience and incidental sampling is that convenience sampling chooses the easiest people to reach when a sampling is done, whereas incidental sampling is done at random.
Sampling error leads to random error. Sampling bias leads to systematic error.
Heat transfer can be unidirectional (one-way transfer of heat from one object to another), such as in conduction or convection, or bidirectional (two-way transfer of heat between two objects), such as in radiation. The direction of heat transfer depends on the temperature difference between the objects involved and the properties of the materials.

the difference is just that non-probability sampling does not involve random selection, but probability sampling does.
