This three-dimensional (3D) vector can be represented by three numbers. It can also be represented by the distance travelled and the direction, angles made to the floor and the angle made to the wall. Velocity is an example of a vector quantity. This can be described by two things, the...
The magnetic flux (measured in Webers) is also one of the scalar quantities that are used in several applications. While the magnetic field is a vector quantity, has a direction, and is defined at each point; the magnetic flux measures how much the magnetic field acts upon a certain area ...

The current theories of quantum physics and general relativity on their own do not allow us to study situations in which the gravitational source is quantum. Here, we propose a strategy to determine the dynamics of objects in the presence of mass configurations in superposition, and hence an ind...
This quantity is time dependent because of dispersal. We distinguish the average range of a species, which is its range averaged over its lifetime, and its maximum range, i.e. the largest range that it occupied during its lifetime. Distance: We measure the distance between two habitats as ...
Velocity: Velocity is a physical quantity which is defined as the rate of change in the position of an object in a certain direction. Since it has both magnitude and direction, it is a vector. In a simple form, v = d/t where v is velocity, d is displacement (change ...
Thus the gradient vector of the NLL is: \begin{aligned} \nabla_{\boldsymbol{w}} \mathrm{NLL}(\boldsymbol{w}) & =-\frac{1}{N} \sum_{n=1}^N\left[y_n\left(1-\mu_n\right) \boldsymbol{x}_n-\left(1-y_n\right) \mu_n \boldsymbol{x}_n\right] \\ & \left.=-\frac{...
Refractivity is defined as the macroscopic response of a system of charged particles to an externally applied electric field, where a positive refractivity implies a polarization parallel to the field, while a negative refractivity indicates an antiparallel polarization observed in certain materials at spe...
For periodic systems, the displacement field is again defined with respect to a reference ‘equilibrium’ configuration, this time a lattice of reciprocal vector K0. The analogous quantity to the roughness is then the translational order correlation function CK0(r) defined as (5)CK0(r)≡〈eiK0...
Self-testing is the most accurate form of certification of quantum devices. While self-testing in bipartite Bell scenarios has been thoroughly studied, self-testing in the more complex multipartite Bell scenarios remains largely unexplored. We present a simple and broadly applicable self-testing scheme...
