Scalar quantities can be manipulated by the laws of arithmetic applicable to natural numbers. For example if I add 20 grams of sugar to a recipe and then add 20 grams more the result is 40 grams of sugar in the recipe. If I buy a liter (1000ml) bottle of water and drink 250 ml, ...
D is a diagonal self-decay matrix, ψα(⋅) is an element-wise sigmoidal nonlinearity whose steepness is determined by each element of the vector α (which is also the same size as x), and \({{{\mathcal{H}}}(q)\) is a scalar linear HRF that is the same and fixed a priori...
Using the complete parameter space of the Standard Model extended by a real scalar singlet with a Z2 symmetry as a test, we explore the properties of the electroweak phase transition in general Rξ and covariant gauges, OS and MS renormalisation schemes, and for common treatments of the ...
Social conventions change when individuals collectively adopt an alternative over the status quo, in a process known as social diffusion. Our repeated trials of a multi-round experiment provided data that helped motivate the proposal of an agent-based mo
Considering above one may suppose for instance the scalar strain variable E as such a process, i.e. E(,t) E0() E () t (25) where superscript 0 denotes here the initial random distribution of the given parameter and dotted quantities stand for the random ...
The Bayesian model has two regression coefficient parameters, {wage:age} and {wage: cons}, and a positive scalar parameter, {sigma2}, representing the variance of the error term. The model sum- mary shows the default priors used for the model parameters: normal(0, 10000) for the ...
where the index X can be either X = D or X = P, which indicates quantities depending on the correlations with data and pilot local code replicas respectively; N is the number of samples used in the evaluation of the correlations between the received and local signals. The in-phase and ...
When we measure things in Science - we not only must know how much (magnitude) but in what direction. This is important - Direction Matters!! To add two (or more) vectors together graphically using the head-to-tail method you simply draw the first vector anywhere you wish, then draw the...
Among the commonalities of the challenges are that the DNA from protozoan transmission stages in faecal samples or environmental samples is not always easily accessible for amplification, and may be in small quantities or be of low quality. This encourages researchers to use multicopy genes, such ...
