We report, for the first time, long-awaited detection of diffuse gamma rays with energies between 100 TeV and 1 PeV in Galactic disk. Particularly, all above 398 are observed apart from known gamma-ray sources compatible expectations hadronic emission scenario which originate decay $π^0$'s produced through interaction protons interstellar medium Galaxy. This is strong evidence that cosmic accelerated beyond our Galaxy spread over
We report on the highest energy photons from Crab Nebula observed by Tibet air shower array with underground water-Cherenkov-type muon detector array. Based criterion of a number measured in an shower, we successfully suppress 99.92% cosmic-ray background events energies E>100 TeV. As result, 24 photonlike TeV against 5.5 events, which corresponds to 5.6σ statistical significance. This is first detection astrophysical source.
Utilizing infrastructure and vehicle-side information to track forecast the behaviors of surrounding traffic participants can significantly improve decision-making safety in autonomous driving. However, lack real-world sequential datasets limits research this area. To address issue, we introduce V2X-Seq, first large-scale V2X dataset, which includes data frames, trajectories, vector maps, lights captured from natural scenery. V2X-Seq comprises two parts: perception more than 15,000 frames 95...
In this article, entropy generation of an Eyring–Powell nanofluid through a permeable stretching surface has been investigated. The impact magnetohydrodynamics (MHD) and nonlinear thermal radiation are also taken into account. governing flow problem is modeled with the help similarity transformation variables. resulting ordinary differential equations solved numerically combination Successive linearization method Chebyshev spectral collocation method. all emerging parameters such as Hartmann...
In this paper, the laminar forced convection heat transfer of nanofluid through a bent channel was numerically investigated. The lattice Boltzmann method used for solving governing equations in domain. effect different parameters such as Reynolds number (50 ≤ Re 150), vertical passage ratio (2.0 M 4.0), and nanoparticle solid volume fractions (Φ = 0, 0.01, 0.03, 0.05) are analyzed terms streamlines, isotherms, local Nusselt numbers. It concluded from study that average increased with...

Abstract We report on the analysis of 10–1000 TeV large-scale sidereal anisotropy Galactic cosmic rays (GCRs) with data collected by Tibet Air Shower Array from 1995 October to 2010 February. In this analysis, we improve energy estimate and extend decl. range down −30°. find that maps above 100 are distinct at a multi-TeV band. The so-called tail-in loss-cone features identified low energies get less significant, new component appears ∼100 TeV. spatial distribution GCR intensity an excess...
The wake dynamics of a rectangular flat-backed bluff body is studied using both the wind tunnel experiment and Improved Delayed Detached Eddy Simulation (IDDES) at Re = 9.2 × 104. Both approaches are systematically investigated in order to provide quantitative comparison. barycenter deficit base pressure gradient first characterize states. Second, known global such as long-term bi-stability, vortex shedding, pumping analyzed proper orthogonal decomposition. It found that globally well...
The flow around a seal-vibrissa-shaped cylinder (SVSC) is numerically investigated using the large eddy simulation framework at Reynolds number of 20 000. Compared with circular (CC), wake SVSC presents more stable three-dimensional separation, longer vortex formation length, and weaker strength. mean drag fluctuation lift coefficient are 59.5% 87.7% lower than those CC, respectively. Three-dimensional spectral proper orthogonal decomposition (SPOD) used to investigate turbulent these two...
Purpose This paper aims to numerically investigate the natural convection heat transfer of multi-wall carbon nanotubes (MWCNTs)-water nanofluid in U-shaped enclosure equipped with a hot obstacle by using lattice Boltzmann method.

We address a challenge of active flow control: the optimization many actuation parameters guaranteeing fast convergence and avoiding suboptimal local minima. This is addressed by new optimizer, called explorative gradient method (EGM). EGM alternatively performs one exploitive downhill simplex step an Latin hypercube sampling iteration. Thus, rate based guaranteed while, at same time, better minima are explored. For analytical multi-modal test function, shown to significantly outperform...
