Abstract: Water Cherenkov detector array (WCDA) is one of the key parts of the Large High Altitude Air Shower Observatory (LHAASO), the construction of which was completed by the end of 2020. The WCDA covers a 78 000-m2 area and there exist 3120 large size photomultiplier tubes (PMTs) in three ponds: 8-in PMTs are used in WCDA pond No. 1 and 20-in PMTs are used in ponds No. 2 and No. 3. The front-end electronics (FEE) system based on multigain measurement technique is designed to achieve both high-precision time and charge measurements over a large dynamic range from single photon electron (S.P.E.) to 4000 P.E. (for water pond No. 1)/1800 P.E. (for water ponds No. 2 and No. 3). To achieve a high-quality clock distribution and phase alignment as well as mixed transmission of data, clock, and commands in one fiber over a long distance, an enhanced white rabbit (WR) technique is used. Testing of all the 350 FEE modules for the WCDA is presented in this article. Test results indicate that the charge resolution is better than 20% at S.P.E. and 1% at 1800/4000 P.E. and the time resolution is better than 300 ps root mean square (rms), which successfully meets the application requirement. All the FEE modules have been fabricated and installed for the LHAASO WCDA from 2018 to 2020, and the initial commissioning operation indicates that the FEEs function well. more...

Abstract: Owing to the high strength of copper (Cu) and high in-plane thermal conductivity (Kr) of graphene (Gr), Gr/Cu composites are increasingly demanded as the advanced thermal management materials to ensure the heat dissipation. The heat transport performance is primarily influenced by two aspects: (1) Intrinsic parameters of Gr, including its crystallinity, layer number (N), coverage and spatial distribution and (2) Gr/Cu interface related properties, such as interface bonding, residual strain and defects near the interface. In this work, by combining roll-to-roll (R2R) chemical vapor deposition (CVD) and subsequent hot isostatic pressing (HIP) techniques, highly paralleled Gr reinforced Cu matrix composites with controllable N were fabricated. Experimental results show that ~5–6L Gr/Cu composites manifest the highest degree of anisotropy, including (1) the highest Kr (394 ± 5 W/mK, ~22% higher than pure Cu counterpart), and (2) the lowest through-plane thermal conductivity (Kz) (257 ± 4 W/mK, ~25% lower than pure Cu counterpart). When N varies from 1 to 5, the continuously increased Kr and decreased Kz are majority influenced by intrinsic properties of Gr, which is also validated by multiscale simulations and time-domain thermoreflectance analysis. When N increases to ~10, both Kr and Kz exhibit opposite trend, that may attribute to the reduced Gr coverage and large volume fraction of amorphous carbon. Moreover, the residual strain and defects at the interface could lower both Kr and Kz as well. This study suggests that advanced synthesis of high-crystallinity thick Gr may be promising to obtain superb Kr in Cu matrix composites. more...

Abstract: The first Water Cherenkov detector of the LHAASO experiment (WCDA-1) has been operating since April 2019. The data for the first year have been analyzed to test its performance by observing the Crab Nebula as a standard candle. The WCDA-1 achieves a sensitivity of 65 mCU per year, with a statistical threshold of 5 . To accomplish this, a 97.7% cosmic-ray background rejection rate around 1 TeV and 99.8% around 6 TeV with an approximate photon acceptance of 50% is achieved after applying an algorithm to separate gamma-induced showers. The angular resolution is measured using the Crab Nebula as a point source to be approximately 0.45° at 1 TeV and better than 0.2° above 6 TeV, with a pointing accuracy better than 0.05°. These values all match the design specifications. The energy resolution is found to be 33% for gamma rays around 6 TeV. The spectral energy distribution of the Crab Nebula in the range from 500 GeV to 15.8 TeV is measured and found to be in agreement with the results from other TeV gamma ray observatories. more...

Abstract: A reliable prediction of roof stability in stratiform or deteriorated rock banks remains a difficult problem in tunnel engineering, while it is still one of the most classical engineering issues needed to be investigated so as to provide relevant reference to practical projects. In previous research, homogeneous geomaterials were adopted to determine the analytic solutions of collapse profile in Hoek–Brown rock masses. However, when rock heterogeneities are considered in different rock layers, the results gained from existing collapse mechanisms would underestimate the dimensions of falling blocks. Thus in this paper, a new curved failure mechanism constructed with two continuous lines intersecting at the interface, namely progressive failure mechanism, is employed to derive the analytic solutions of the shape and region of roof collapse on the basis of upper bound theorem and variational approach. The corresponding results calculated are in well accordance with the existing findings, which shows sound agreement and validity of the proposed mechanism, and from which one can notice that additional detaching blocks would occur apart from the initial collapsing block when there exist various rock layers with different mechanical parameters, due to physical erosion or other factors, such as weathering process. To investigate the influence of different parameters on the range of roof failure, special attention is given to some examples of square and circular tunnels, and the results computed can give some instruction for practical engineering projects. more...

Abstract: Using the data sets taken at center-of-mass energies above 4 GeV by the BESIII detector at the BEPCII storage ring, we search for the reaction e+eââÎ³ISRX(3872)âÎ³ISRÏ+ÏâJ/Ï via the Initial State Radiation technique. The production of a resonance with quantum numbers JPC=1++ such as the X(3872) via single photon e+eâ annihilation is forbidden, but is allowed by a next-to-leading order box diagram. We do not observe a significant signal of X(3872) , and therefore give an upper limit for the electronic width times the branching fraction ÎeeX(3872)B(X(3872)âÏ+ÏâJ/Ï) more...

Abstract: We study D0D¯0 pairs produced in e+e− collisions at s=3.773 GeV using a data sample of 2.92 fb −1 collected with the BESIII detector. We measured the asymmetry AKπCP of the branching fractions of D→K−π+ in CP -odd and CP -even eigenstates to be (12.7±1.3±0.7)×10−2 . AKπCP can be used to extract the strong phase difference δKπ between the doubly Cabibbo-suppressed process D¯0→K−π+ and the Cabibbo-favored process D0→K−π+ . Using world-average values of external parameters, we obtain cosδKπ=1.02±0.11±0.06±0.01 . Here, the first and second uncertainties are statistical and systematic, respectively, while the third uncertainty arises from the external parameters. This is the most precise measurement of δKπ to date. more...

Abstract: Using 2917 pb−1 of data accumulated at 3.773 GeV , 44.5 pb−1 of data accumulated at 3.65 GeV and data accumulated during a ψ(3770) line-shape scan with the BESIII detector, the reaction e+e−→pp¯ is studied considering a possible interference between resonant and continuum amplitudes. The cross section of e+e−→ψ(3770)→pp¯ , σ(e+e−→ψ(3770)→pp¯) , is found to have two solutions, determined to be (0.059−0.020+0.070±0.012) pb with the phase angle ϕ=(255.8−26.6+39.0±4.8)° ( <0.166 pb at the 90% confidence level), or σ(e+e−→ψ(3770)→pp¯)=(2.57−0.13+0.12±0.12) pb with ϕ=(266.9−6.3+6.1±0.9)° both of which agree with a destructive interference. Using the obtained cross section of ψ(3770)→pp¯ , the cross section of pp¯→ψ(3770) , which is useful information for the future PANDA experiment, is estimated to be either (9.8−3.9+11.8) nb ( <27.5 nb at 90% C.L.) or (425.6−43.7+42.9) nb . more...

Abstract: We present the first upper-limit measurement of the branching fractions of the isospin-violating transitions ?c0,2 ? ?0?c. The measurements are performed using 106×106?(3686) events accumulated with the BESIII detector at the BEPCII e+e- collider at a center-of-mass energy corresponding to the ?(3686) mass. We obtained upper limits on the branching fractions at a 90% confidence level of B(?c0? ?0?c), NSF more...

Abstract: Objective: Using ethology and functional magnetic resonance imaging (fMRI) to explore mild cognitive dysfunction and spatial working memory (WM) impairment in patients with systemic lupus erythematosus (SLE) without overt neuropsychiatric symptoms (non-NPSLE) and to study whether any clinical biomarkers could serve as predictors of brain dysfunction in this disease., Methods: Eighteen non-NPSLE patients and 18 matched subjects were all tested using the Montreal cognitive assessment scale test and scanned using blood-oxygen-level dependent fMRI while performing the n-back task to investigate the activation intensity of some cognition-related areas., Results: Ethology results showed that non-NPSLE patients had mild cognitive dysfunction and memory dysfunction (p < 0.05). The fMRI scan confirmed a neural network consisting of bilateral dorsolateral prefrontal cortex (DLPFC), premotor area, parietal lobe, and supplementary motor area (SMA)/anterior cingulate cortex (ACC) that was activated during the n-back task, with right hemisphere dominance. However, only the right SMA/ACC showed a load effect in the non-NPSLE group; the activation intensity of most WM-related brain areas for the non-NPSLE group was lower than for the control group under 3 memory loads. Further, we found that the activation intensity of some cognition-related areas, including the bilateral caudate nucleus/insula and hippocampus/parahippocampal gyrus were lower than the control group under the memory loads. An inverse correlation existed between individual activation intensity and disease duration., Conclusion: Non-NPSLE-related brain damage with right DLPFC-posterior parietal lobe and parahippocampal gyrus default network causes impairment of spatial WM and mild cognitive dysfunction. Patients with longer disease duration would be expected to exhibit increased central nervous system damage. more...
