Abstract In this work, we propose to search for the exotic doubly charmed meson $$T_{cc}^+$$ T cc + and its analog $$T_{cc\bar{s}}^+$$ c s ¯ in $$B_...

This paper, as part of the activities developed in scope a R&D+I, review is carried out fundamentals switched, average and small-signal models DC-DC converters, order to provide clear objective concepts. Starting from PWM modulator, concepts switching function its Fourier series decomposition are presented obtain switched model converter. Based on averaging operator, averaged stationary states ...

‎A finite group $G$ is called a $CC$-group ($Gin CC$) if the centralizer of each noncentral element of $G$ is cyclic‎. ‎In this article we determine all finite $CC$-groups.

Deep eutectic solvents (DESs) is a newly developed green solvent with low cost, easy preparation and regeneration. Because of its excellent solubility swelling effect in lignocellulose, it has received widespread attention recognition. In this study, choline-based deep (DESs)—choline chloride-urea (CC-U), choline chloride-ethylene glycol (CC-EG), chloride-glycerol (CC-G), chloride-lactic acid (...
