We report the first measurements of seventh and eighth-order cumulants net-proton distributions in Au+Au collisions at √S NN =27,54.4, 200 GeV. The are performed mid-rapidity | y < 0.5 within 0.4 p T 2.0 GeV/ c using Time Projection Chamber Time-of-Flight detector. Motivation for comes from lattice-QCD QCD based model calculations that predict their negative signs a crossover quark-hadron tr...

Ganji and Abdollahzadeh [D.D. Ganji, M. Abdollahzadeh, Appl. Math. Comput. 206 (2008) 438–444] derived three supposedly new travelling-wave solutions to Lax’s seventh-order KdV equation. Each solution was obtained by a different method. It is shown that any two of the solutions may be obtained trivially from the remaining solution. Furthermore it is noted that one of the solutions has been know...

We study the solutions of the one dimensional focusing NLS equation. Here we construct new deformations of the Peregrine breather of order 7 with 12 real parameters. We obtain new families of quasirational solutions of the NLS equation. With this method, we construct new patterns of different types of rogue waves. We recover triangular configurations as well as rings isolated. As already seen i...

Read/write channels for hard disk drives (HDD) require high-frequency continuous time filters (CTF) [1-5]. A 650 MHz current-mode seventh-order 0.05° equiripple linear phase low-pass filter for computer hard disk read/write channels with data rates up to 1Gbit/s is presented in this paper. It is implemented in CMOS using a leap-frog multiple loop feedback structure. The operational transconduct...
