概述了铸坯与结晶器间的保护渣传热,总结了国内外近年来关于保护渣传热检测方法和传热计算的研究现状,并指出现有保护渣传热性能检测方法为一维传热原理,可以反映保护渣的基本传热性能并作为选择保护渣的依据。认为目前的研究只对保护渣的渣膜结构进行了简单的处理或忽略了结晶器弯月面区域的保护渣传热,需进一步加强铸坯与结晶器间保护渣的传热计算。

We report the radio observations of the eclipsing black widow pulsar J1720-0534, a 3.26 ms pulsar in orbit with a low mass companion of mass 0.029 to 0.034 M⊙. We obtain the phase-connected timing ephemeris and polarization profile of this millisecond pulsar(MSP) using the Five-hundred-meter Aperture Spherical radio Telescope(FAST), the Green Bank Telescope(GBT), and the Parkes Telescope. For the first time from such a system, an oscillatory polarization angle change was observed from a particular eclipse egress with partial depolarization, indicating 10-milliGauss-level reciprocating magnetic fields oscillating in a length scale of 5 ×10^(3)km(assuming an orbital inclination angle of 90°) outside the companion's magnetosphere. The dispersion measure variation observed during the ingresses and egresses shows the rapid raising of the electron density in the shock boundary between the companion's magnetosphere and the surrounding pulsar wind. We suggest that the observed oscillatory magnetic fields originate from the pulsar wind outside the companion's magnetosphere.

Recently, Worobey et al.(2022) published a report entitled ‘The Huanan Seafood Wholesale Market in wuhan was the early epicenter of the COVID-19 pandemic’ that succinctly summarizes their study [1]. A pre-print version of this study had earlier elicited a series of highprofile media coverages [2,3]. All these reports deliver a social-political message that the Huanan market is the epicenter of COVID-19.

Mammalian target of rapamycin(m TOR) inhibitor as an attractive drug target with promising antitumor effects has been widely investigated. High quality clinical trial has been conducted in liver transplant(LT) recipients in Western countries. However, the pertinent studies in Eastern world are paucity. Therefore, we designed a clinical trial to test whether sirolimus can improve recurrence-free survival(RFS) in hepatocellular carcinoma(HCC) patients beyond the Milan criteria after LT. This is an open-labeled, single-arm, prospective, multicenter, and real-world study aiming to evaluate the clinical outcomes of early switch to sirolimus-based regimens in HCC patients after LT. Patients with a histologically proven HCC and beyond the Milan criteria will be enrolled. The initial immunosuppressant regimens are center-specifc for the frst 4-6 weeks. The following regimens integrated sirolimus into the regimens as a combination therapy with reduced calcineurin inhibitors based on the condition of patients and centers. The study is planned for 4 years in total with a 2-year enrollment period and a 2-year follow-up. We predict that sirolimus conversion regimen will provide survival benefts for patients particular in the key indicator RFS as well as better quality of life. If the trial is conducted successfully, we will have a continued monitoring over a longer follow-up time to estimate indicator of overall survival. We hope that the outcome will provide better evidence for clinical decision-making and revising treatment guidelines based on Chinese population data.

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

Background:Disease-modifying therapy is the standard treatment for patients with multiple sclerosis (MS)in *** primary objective of the current analysis was to assess the efficacy and safety of two teriflunomide doses (7mg and 14mg)in the subgroup of Chinese patients with relapsing MS included in the TOWER study. Methods:TOWER was a multicenter,multinational,randomized, double-blind,parallel-group (three groups),placebo-controlled *** subgroup analysis includes 148 Chinese patients randomized to receive either teriflunomide 7mg (n =51), teriflunomide 14mg (n=43),or placebo (n=54). Results:Of the 148patients in the intent-to-treat population, adjusted annualized-relapse rates were 0.63(95% confidence interval [CI]:0.44,0.92)in the placebo group,0.48(95%CI:0.33, 0.70)in the teriflunomide 7mg group,and 0.18(95%CI:0.09,0.36)in the terifltmomide 14mg group;this corresponded to a significant relative risk reduction in the teriflunomide 14mg group versus placebo (-71.2%,P =0.0012).Terifiunomide 14mg also tended to reduce 12-week confirmed disability worsening by 68.1% compared with placebo (hazard ratio:0.319,P =0.1194).There were no differences across all treatment groups in the proportion of patients with treatment-emergent adverse events (TEAEs;72.2% in the placebo group,74.5%in the teriflunomide 7mg group,and 69.8% in the teriflunomide 14mg group);corresponding proportions for serious adverse events were 11.1%,3.9%,and 11.6%,*** most frequently reported TEAEs with teriflunomide versus placebo were neutropenia,increased alanine aminotransferase,and hair thinning. Conclusions:Teriflunomide was as effective and safe in the Chinese subpopulation as it was in the overall population of patients in the TOWER *** has the potential to meet unmet medical needs for MS patients in China.
