The decay channel Ψ' → π+π− J/Ψ(J/Ψ γp) is studied using a sample of 1.06 × 108 events collected by the BESIII experiment at BEPCII. A strong enhancement threshold observed in p invariant mass spectrum. can be fitted with an S-wave Breit–Wigner resonance function resulting peak M = 1861+6−13 (stat)+7−26 (syst) MeV/c2 and narrow width that Γ < 38 90% confidence level. These results are consistent published BESII results. values do not match well established mesons.
The number of ψ' events accumulated by the BESIII experiment from March 3 through April 14, 2009, is determined counting inclusive hadronic events. result 106.41×(1.00±0.81%)×106. error systematic dominant; statistical negligible.
Remote sensing and deep learning are being widely combined in tasks such as urban planning disaster prevention. However, due to interference occasioned by density, overlap, coverage, the tiny object detection remote images has always been a difficult problem. Therefore, we propose novel TO–YOLOX(Tiny Object–You Only Look Once) model. TO–YOLOX possesses MiSo(Multiple-in-Single-out) feature fusion structure, which exhibits spatial-shift model balances positive negative samples enhances...
Frequent landslide disasters on the Loess Plateau in northwestern China have had a serious impact lives and production of people region due to fragile ecological environment severe soil erosion. The effective monitoring management hazards is hindered by wide range features scales remotely sensed imagery, coupled with shortage local information technology. To address this issue, we constructed loess dataset 11,010 images established detection network model. Coordinate Attention (CA)...
The exploration and development of marine geothermal energy is a field with significant potential, but it also one that presents considerable challenges costs. assessment reservoir potential currently based on subjective analysis, this study proposes an innovative clustering-based method to classify reservoirs systematically. Yingqiong Basin was analysed develop machine learning framework predict the (CPPOGR). integrated eight key features into unified dataset, employing dimensionality...
The increasing tensions between urban development and ecological environments in China, as evidenced by the country’s rapidly globalising urbanising society, pose significant challenges to implementation of sustainable strategies. In order evaluate coupled coordination degree (CCD) regional (RD) carrying capacity (ECC) within Chengdu-Chongqing Twin Cities Economic Circle, this study proposes a comprehensive CCD evaluation framework. This framework includes indicator analysis, quantitative...
We search for the M1 radiative transition \psi(3686) \to \gamma\eta_{c}(2S) by reconstructing exclusive \eta_{c}(2S) K_{S}^{0}K^{\pm}\pi^{\mp}\pi^{+}\pi^{-} decay using 1.06 \times 10^8 events collected with BESIII detector. The signal is observed a statistical significance of greater than 4 standard deviations. measured mass 3646.9 \pm 1.6(stat) 3.6(syst) MeV/c^2, and width 9.9 4.8(stat) 2.9(syst) MeV/c^2. product branching fraction to be B(\psi(3686) \gamma\eta_{c}(2S)) B(\eta_{c}(2S)...
Shale gas, a significant recoverable natural gas resource trapped in shale formations, represents energy reservoir. Although China has reserves, the challenge of controlling drilling costs remains critical barrier to efficient development. This study presents novel stacked ensemble learning model that integrates support vector machine (SVM) and long short-term memory (LSTM) networks improve accuracy cost prediction. The methodology consists three main phases. First, we constructed...
Using a data sample of $2.25\times10^{8}$ $J/ψ$ events collected with the BESIII detector, we present first observation decays $η_{c}$ mesons to $Σ^{+}\barΣ^{-}$ and $Ξ^{-}\barΞ^{+}$. The branching fractions are measured be $(2.11\pm0.28_{\rm stat.}\pm0.18_{\rm syst.}\pm0.50_{\rm PDG})\times10^{-3}$ $(0.89\pm0.16_{\rm stat.}\pm0.08_{\rm syst.}\pm0.21_{\rm for $η_{c} \to Σ^{+}\barΣ^{-}$ $Ξ^{-}\barΞ^{+}$, respectively. These provide important information on helicity selection rule in...
Ocean geothermal energy has significant potential for development, but it comes with higher exploration costs and greater development challenges. Therefore, pre-analysis simulation of offshore are imperative. Our study area is the Ying-Qiong Basin within South China Sea region, where we conducted a formal pre-development 102 marine reservoir data compiled in this region. We aim to utilize cluster analysis classify reservoirs found compare attributes each category. This process allows...
