In ρ photoproduction in ultra-peripheral heavy ion collisions, either ion can be the photon emitter or the target. The two possibilities are indistinguishable, and they should be able to interfere, reducing rho production at low transverse momentum, pT < h̄/〈b〉, where 〈b〉 is the median impact parameter. The two ρ production points are separated by 〈b〉 ≈ 18−46 fm, while the ρ decay before travell...

The impregnation method was used to synthesize Pt and Pt3Co supported on MWCNTs applying NaBH4 as the reducing agent. The structure, morphology, and chemical composition of the electrocatalysts were characterized through SEM, XRD, and EDX. X-ray diffraction showed a good crystallinity of the supported Pt nanoparticles on the composites and showed the formation of Pt3<...

Attention-based Transformer models have been increasingly employed for automatic music generation. To condition the generation process of such a model with user-specified sequence, popular approach is to take that conditioning sequence as priming and ask decoder generate continuation. However, this prompt-based cannot guarantee would develop or even simply repeat itself in generated In p...
