We consider a correspondence between the tachyon dark energy model and Barrow holographic (BHDE). The latter is modified scenario based on application of principle with entropy instead usual Bekenstein–Hawking one. reconstruct dynamics scalar field T in curved Friedmann–Robertson–Walker universe both presence absence interactions matter. As result, we show that exhibits non-trivial dynamics. In flat universe, T˙2 must always be vanishing, independently existence interaction. This implies...
Knowledge graphs (KGs) often contain various errors. Previous works on detecting errors in KGs mainly rely triplet embedding from graph structure. We conduct an empirical study and find that these struggle to discriminate noise semantically-similar correct triplets. In this paper, we propose a KG error detection model CCA integrate both textual structural information reconstruction for better distinguishing semantics. design interactive contrastive learning capture the differences between...
The process J/ψ--> p \bar{p} is studied using 57.7 X 10^6 J/ψevents collected with the BESII detector at Beijing Electron Positron Collider. branching ratio determined to be Br(J/ψ--> \bar{p})=(2.26 +- 0.01 0.14) 10^{-3}, and angular distribution well described by \frac{dN}{d cosθ_p}=1+α\cos^2θ_p α= 0.676 0.036 0.042, where θ_p angle between proton beam directions. value of αobtained in good agreement predictions first-order QCD.
The mechanism of regulating hydrogen bond organization for polyamide 6,6 (PA 6,6) by nigrosine was investigated temperature-dependent FTIR and in situ synchrotron X-ray diffraction during cooling/heating processes. intermolecular interaction between amide groups verified the spectroscopy method. Upon melt cooling, formation H-bonds is promoted at initial stage (regime I) with increased enthalpy change (ΔH1), which results from denser molecular coils as increases ability to form adjacent...
The DArk Matter Particle Explorer (DAMPE) is a space-borne high-energy particle detector launched on 17 December 2015. It can observe the $\gamma$-ray sky from $\sim 2$ GeV to 10 TeV with acceptance at most $1800~\rm cm^2\,sr$. With over 7.5 years of continuous operation, DAMPE has surveyed whole for about 15 times and collected more than 300,000 candidate photon events. In last few years, understanding payload been improved instrumental response functions have calibrated on-board data....
Neutron scattering instruments play an important role in studying the inner structure of materials. A neutron beam monitor is a detector commonly used instrument. The detection efficiency for most monitors quite low (10-4-10-6). However, some experiments with flux, such as small angle (SANS) and inelastic experiments, higher (∼1% thermal neutrons) required to reduce duration experiment. To meet this requirement, ceramic gas electron multiplier-based equipped 1 µm 10B4C converter was...
We report the test results of several independent foreground-cleaning pipelines used in Ali CMB Polarization Telescope experiment (AliCPT-1), a high-altitude imager Northern hemisphere with thousands detectors dedicated to search for primordial polarization $B$-mode signature. Based on simulated data from 4 detector modules and single season observation, which we refer as DC1 data, employ different examine robustness effectiveness estimates foreground parameters detection. The strategies...
Political and theoretical education forms the core of socialist development, with Graduate medical serving as vital arenas for talent cultivation educational advancement. As practical skills gain prominence in curricula, it's imperative to enhance quality ideological political instruction. Presently, there's a lack standardized evaluation criteria such courses. This study addresses key issues at university level proposes systematic framework. Through analytic hierarchy process, we...
The widespread use of diffusion methods enables the creation highly realistic images on demand, thereby posing significant risks to integrity and safety online information highlighting necessity DeepFake detection. Our analysis features extracted by traditional image encoders reveals that both low-level high-level offer distinct advantages in identifying produced various methods. Inspired this finding, we aim develop an effective representation captures detect diffusion-based DeepFakes. To...
The CODEX-$\beta$ apparatus is a demonstrator for the proposed future CODEX-b experiment, long-lived-particle detector foreseen operation at IP8 during HL-LHC data-taking. project, intended to collect data in 2025, described, with particular focus on design, construction, and installation of new apparatus.
We investigate the effect of quantum correction on Hawking radiation for Schwarzschild black holes. consider temperature and entropy to order G^2 find that area law holes should be modified. think as tunneling at certain frequency {\omega} spectrum can pure blackbody spectrum. Therefore, it is possible break down information conservation. In ensure conservation any energy scales, we suggest cannot release all they have. briefly discuss bound greybody factors well. Since modification horizon...
Neutron imaging technology as a means of non-destructive detection materials is complementary to X-ray imaging. Silicon photomultiplier (SiPM), new type optical readout device, has overcome some shortcomings traditional tube (PMT), such high-power consumption, large volume, high price, uneven gain response, and inability work in strong magnetic fields. Its application the field neutron will be an irresistible general trend. In this paper, thermal detector based on 6LiF/ZnS scintillation...

Galactic cosmic rays are mostly made up of energetic nuclei, with less than 1% electrons (and positrons). Precise measurement the electron and positron component requires a very efficient method to reject nuclei background, mainly protons. In this work, we develop an unsupervised machine learning identify positrons from ray protons for Dark Matter Particle Explorer (DAMPE) experiment. Compared supervised used in DAMPE experiment, relies solely on real data except background estimation...
