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.
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...
Cosmic rays are hampered by the Moon and a deficit in its direction is expected (the so-called shadow). The shadow an important tool to determine performance of air shower array. Indeed, westward displacement center, due bending effect geomagnetic field on propagation cosmic rays, allows setting absolute rigidity scale primary particles inducing showers recorded detector. In addition, shape permits detector point spread function, while position at high energies evaluation pointing accuracy....

The proton-air cross section in the energy range 1--100 TeV has been measured by ARGO-YBJ cosmic ray experiment. analysis is based on primary flux attenuation for different atmospheric depths (i.e. zenith angles) and exploits detector capabilities of selecting shower development stage means hit multiplicity, density lateral profile measurements at ground. effects fluctuations, contribution heavier primaries uncertainties hadronic interaction models, have taken into account. results used to...

We report on a clear solar-cycle variation of the Sun's shadow in 10 TeV cosmic-ray flux observed by Tibet air shower array during full solar cycle from 1996 to 2009. In order clarify physical implications variation, we develop numerical simulations shadow, using potential field source surface model and current sheet (CSSS) for coronal magnetic field. find that intensity deficit simulated is very sensitive structure, better reproduced CSSS model. This first successful attempt evaluate models flux.
In 2008, the blazar Markarian 421 entered a very active phase and was one of brightest sources in sky at TeV energies, showing frequent flaring episodes. Using data ARGO-YBJ, full coverage air shower detector located Yangbajing (4300 m a.s.l., Tibet), we monitored source gamma-ray energies E>0.3 during whole year. The observed flux variable, with strongest flares March June, correlation X-ray enhanced activity. While specific episodes could be several times larger than Crab Nebula one,...

We report observations of gamma-ray emissions with energies in the 100 TeV energy region from Cygnus our Galaxy. Two sources are significantly detected directions OB1 and OB2 associations. Based on their positional coincidences, we associate one a pulsar PSR J2032+4127 other mainly wind nebula PWN G75.2+0.1 moving away its original birthplace situated around centroid observed emission. This work would stimulate further studies particle acceleration mechanisms at these sources.
Abstract Innate immune activation is critical for initiating hepatic inflammation during nonalcoholic steatohepatitis (NASH) progression. However, the mechanisms by which immunoregulatory molecules recognize lipogenic, fibrotic, and inflammatory signals remain unclear. Here, we show that high-fat diet (HFD)-induced oxidative stress activates Foxo1, YAP, Notch1 signaling in macrophages. Macrophage Foxo1 deficiency (Foxo1 M-KO ) ameliorated inflammation, steatosis, fibrosis, with reduced...

A total 3560 participants aged 18-60 years from various provinces cities mainland China were included. Sample 1 (n = 3316) was used for CFA, MI, internal consistency, convergent, criterion-related validity, difference analysis. 2 244) employed test-retest reliability over a four-week interval. The validated robust 23-item, five-factor structure...
Transformer-based models have recently achieved outstanding performance in image matting. However, their application to high-resolution images remains challenging due the quadratic complexity of global self-attention. To address this issue, we propose MEMatte, a memory-efficient matting framework for processing images. MEMatte incorporates router before each attention block, directing informative tokens while routing other Lightweight Token Refinement Module (LTRM). Specifically, employs...
We report on the search for gamma ray bursts (GRBs) in energy range 1–100 GeV coincidence with prompt emission detected by satellites using Astrophysical Radiation Ground-based Observatory at YangBaJing (ARGO-YBJ) air shower detector. Thanks to its mountain location (Yangbajing, Tibet, People's Republic of China, 4300 m above sea level), active surface (∼6700 m2 Resistive Plate Chambers), and large field view (∼2 sr, limited only atmospheric absorption), ARGO-YBJ detector is particularly...
The Sun blocks cosmic-ray particles from outside the solar system, forming a detectable shadow in sky map of cosmic rays detected by ARGO-YBJ experiment Tibet. Because are positively charged, magnetic field between and Earth deflects them straight trajectories results shift true location Sun. Here, we show that measures intensity is transported wind to Earth.
Cosmic ray antiprotons provide an important probe to study the cosmic propagation in interstellar space and investigate existence of dark matter. Acting Earth-Moon system as a magnetic spectrometer, paths primary are deflected opposite sense with respect those protons their way Earth. This effect allows, principle, search for antiparticles direction observed deficit rays due Moon (the so-called "Moon shadow"). The ARGO-YBJ experiment, located at Yangbajing Ray Laboratory (Tibet, P.R. China,...
A 100 m2 muon detector (MD) was successfully constructed under the existing Tibet air shower (AS) array in late fall of 2007. The sensitivity AS to cosmic gamma rays can be improved by selecting muon-poor events with MD. Our MC simulation MD response reasonably agrees experimental data terms charge distribution for one-muon and background rejection power. Using collected taken from 2008 March 2010 February, we search continuous gamma-ray emission Crab Nebula above ∼100 TeV. No significant...
