Abstract Using the intermediate coordinate--momentum representation $|x\rangle_{s,r}$, we introduce a new Hadamard transform. It is found that the operator U corresponding to this transform can be considered as a combination of the Fresnel operator $F(r,s)$ and the Fourier transform operator $\mathcal{F}$ by decomposing U. We also find that the matrix element ${}_{s,r}\langle x|U|f\rangle$ just corresponds to an optical scaled Fresnel--Fourier transform.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
