We studied the DD¯⁎/D¯D⁎, D⁎D¯⁎, D¯sD⁎/D¯s⁎D, BB¯⁎/B¯B⁎ and B⁎B¯⁎ di-hadron interactions in chiral effective field theory (χEFT) up to next-to-leading (NLO) order. The above-threshold tetraquark states Zc(3900), Zc(4020), Zcs(3985), Zb(10610), Zb(10650) can be explained as corresponding resonances, respectively. also Σc(⁎)D¯(⁎) investigate three hidden-charm pentaquarks Pc(4312), Pc(4440) Pc(44...

In this article, we analyze the impact of off-axis noncanonical vortex on dynamics 3D energy flux. The results reveal that properties flux are significantly influenced by anisotropy parameter σc vortex. It is demonstrated adjusting parameter, can control transverse flux, from position tornado and distribution strength to rotation direction as beam propagates. interesting phenomenon, reversed al...

We study the diversity of the density profiles of dark matter halos based on a large set of high-resolution cosmological simulations of 256 particles. The cosmological models include four scale-free models and three representative cold dark matter models. The simulations have good force resolution. In each cosmological model, there are about 400 massive halos which have more than 10 particles w...

In a discrete-event framework, we define the concept of a coordinable language and show that it is the necessary and sufficient existence condition of coordination modules for distributed agents to achieve conformance to a given inter-agent constraint language. We also present a synthesis algorithm to compute near optimal coordination modules. Background & Notation We use the following notation...

Inspired by the LHCb observation of hidden-charm pentaquarks, i.e., Pc(4312), Pc(4440), and Pc(4457) in J/ψp invariant mass spectrum, a calculation scattering cross-section was performed using quark-delocalization color screening model. The results show that Pc(4312) can be identified as molecular state ΣcD with JP=12−. two-peak structure reproduced around 4450 MeV, which corresponds to Pc(4440...

We investigate cylindrical and spherical solitons in electron-ion (EI) plasma that contains hot (cold) electrons with stationary ions. The magneto-hydrodynamic equations are solved the aid of reductive perturbation (RP) technique, leading to modified Korteweg–De Vries (mKdV) equation for non-linear behaviour solitary waves EI plasma. By employing reduced differential transform method (RDTM), an...

We present ultra-deep Spitzer 70μm observations of GOODS-North (Great Observatories Origins Deep Survey). For the first time, the turn-over in the 70μm Euclidean-normalized differential source counts is observed. We derive source counts down to a flux density of 1.2mJy. From the measured source counts and fluctuation analysis, we estimate a power-law approximation of the faint 70μm source count...

We investigate the differences in the M• −σ relation derived recently by Ferrarese & Merritt and by Gebhardt and collaborators. The shallower slope found by the latter authors (3.75 vs. 4.8) is due partly to the use of a regression algorithm that ignores measurement errors, and partly to the value of the velocity dispersion adopted for a single galaxy, the Milky Way. A steeper relation is shown...
