We study thermal entanglement in a two-superconducting-qubit system in two cases,either identical or *** calculating the concurrence of system,we find that the entangled degree of the system is greatly enhanced in the case of very low temperature and Josephson energies for the identical superconducting qubits and our result is in a good agreement with the experimental data.

在全面从严治党向基层延伸背景下,基层小微权力的腐败问题却屡禁不止。现阶段,农村微腐败问题主要表现为腐败主体以村两委成员为主、利益目标多重复合、涉事领域众多、贪腐金额巨大,究其原因,是由于腐败机会成本低廉、村干部“边际人”心态、农村社会资本弱化、激励保障措施缺位、组织信息沟通不畅。有鉴于此,在“五治融合”视域下,应从政治引领、自治强基、依法治国、德治教化、智治赋能等五个维度有效治理“微腐败”,营造更加风清气正的农村政治生态。

To identify systems with non-uniformly sampled input data, a recursive Bayesian identification algorithm with covariance resetting is proposed. Using estimated noise transfer function as a dynamic filter, the system with colored noise is transformed into the system with white noise. In order to improve estimates, the estimated noise variance is employed as a weighting factor in the algorithm. Meanwhile, a modified covariance resetting method is also integrated in the proposed algorithm to increase the convergence rate. A numerical example and an industrial example validate the proposed algorithm.

A new Co（ll） polymer [Co（tdc）（l,4-bimb）]n 1 （H2tdc = thiophene-2,3-dicarboxy- lic acid, 1,4-bimb -- 1,4-bis（imidazol-1 ＇-yl）butane） was synthesized under hydrothermal conditions The compound crystallizes in the monoclinic system, space group C2/c with a = 15.643（9）, b = 8.839（5）, c=12.952（7） A, β = 105.964（6）°, V= 1721.8（16） A3, Z = 4, Mr = 419.32, Dc= 1.618 Mg/m3,μ = 1.149 mm-1, F（000） = 860, the final R = 0.0243 and wR =0.0613 for 1460 observed reflections with I 〉 2σ（I）. The compound presents a three-dimensional （3D） network extended by both tdc2- anions and 1,4-bimb ligands in which the tdc2- anions employ a chelating coordination mode. From the topology point of view, the structure could be described as a 3D 4-connected 65.8 CdSO4-type net. Infrared spectroscopy, elemental analyses, thermogravimetric analysis and powder X-ray diffraction properties of 1 are also investigated.

Rational design of low-cost, highly electrocatalytic activity, and stable bifunctional electrocatalysts for oxygen reduction reaction(ORR) and oxygen evolution reaction(OER) has been a great significant for metal–air batteries. Herein, an efficient bifunctional electrocatalyst based on hollow cobalt oxide nanoparticles embedded in nitrogen-doped carbon nanosheets(Co/N-Pg) is fabricated for Zn–air batteries. A lowcost biomass peach gum, consisting of carbon, oxygen, and hydrogen without other heteroatoms, was used as carbon source to form carbon matrix hosting hollow cobalt oxide nanoparticles. Meanwhile, the melamine was applied as nitrogen source and template precursor, which can convert to carbon-based template graphitic carbon nitride by polycondensation process. Owing to the unique structure and synergistic effect between hollow cobalt oxide nanoparticles and Co-N-C species, the proposal Co/N-Pg catalyst displays not only prominent bifunctional electrocatalytic activities for ORR and OER, but also excellent durability. Remarkably, the assembled Zn–air battery with Co/N-Pg air electrode exhibited a low discharge-charge voltage gap(0.81 V at 50 mA cm^-2) and high peak power density(119 mW cm^-2) with long-term cycling stability. This work presents an effective approach for engineering transition metal oxides and nitrogen modified carbon nanosheets to boost the performance of bifunctional electrocatalysts for Zn–air battery.

The β-subunit of RNA polymerase, which is involved in rifampin binding, is highly conserved among prokaryotes, and Rile mutants detected in many bacteria are the result of amino acid changes. Spontaneous rifampin resistance mutations resulting in amino acid replacement （L420R） and deletion （1258-66 9 bp deletion） have been previously isolated in the rpoB gene of Deinococcus radiodurans. In this study, a β-subunit mutation in D. radiodurans resulted in a unique effect on growth rate. We used DNA microarrays and biochemical assays to investigate how the Rif mutation in the β-subunit led to changes in growth rate via altered regulation of multiple genes. The expression of genes with predicted functions in metabolism, cellular processes and signaling, and information storage and processing were significantly altered in the 9 bp-deletion rpoB mutant. The consensus promoter sequence of up-regulated genes in the 9 bp-deletion rpoB mutant was identified as an AT-rich sequence. Greater levels of reactive oxygen species accumulated in the L420R and 9 bp-deletion rpoB mutants compared with wild type. These results provide insight into the molecular mechanism of how the β-subunit Rif mutation alters the regulation of multiple genes.

Emergy analysis is effective for analyzing ecological economic systems. However, the accuracy of the approach is af- fected by the diversity of economic level, meteorological and hydrological parameters in different regions. The present study evalu- ated the economic benefits, environmental impact, and sustainability of indoor, semi-intensive and extensive farming systems of sea cucumber （Apostichopus japonicus） in the same region. The results showed that A. japonicus indoor farming system was high in input and output （yield） whereas pond extensive farming system was low in input and output. The output/input ratio of indoor fann- ing system was lower than that of pond extensive farming system, and the output/input ratio of semi-intensive farming system fell in between them. The environmental loading ratio of *** extensive fanning system was lower than that of indoor farming sys- tem. In addition, the emergy yield and emergy exchange ratios, and emergy sustainability and emergy indexes for sustainable devel- opment were higher in extensive farming system than those in indoor farming system. These results indicated that the current exten- sive farming system exerted fewer negative influences on the environment, made more efficient use of available resources, and met more sustainable development requirements than the indoor farming system. A. japonicus farming systems showed more emergy benefits than fish fanning systems. The pond fanning systems ofA. japonicus exploited more free local environmental resources for production, caused less potential pressure on the local environment, and achieved higher sustainability than indoor farming system.

目的:探讨维奈克拉联合去甲基化药物与强化疗方案治疗急性髓系白血病(AML)的疗效及安全性。方法:回顾性分析2019年1月至2024年3月在山东大学齐鲁医院德州医院接受治疗且可评估疗效的76例AML患者的临床资料,将患者分为观察组(38例)和对照组(38例),观察组接受维奈克拉联合去甲基化药物(地西他滨或阿扎胞苷)治疗,对照组接受“3+7”强化疗方案。临床观察主要终点为完全缓解(CR)、完全缓解伴血液学不完全恢复(CRi)、部分缓解(PR)、未缓解(NR)、总反应率(ORR),次要终点是总生存期(OS)及药物安全性。结果:观察组与对照组在2疗程后CR+CRi率分别为71.05%、65.79%,ORR分别为81.58%、78.95%;在对应方案全部疗程结束后观察组与对照组的CR+CRi率分别为73.68%、78.95%,ORR分别为81.58%、84.21%,两组差异均无统计学意义(P>0.05)。在1疗程后两组发生治疗后骨髓抑制比例、程度及中性粒细胞减少持续时间、血小板减少持续时间上的差异均有统计学意义(P0.05)。非血液学不良反应以感染(以肺部感染为主)和胃肠道反应发生率最高。在众多不良反应中,两组仅感染及低钾血症的比较有统计学意义(P<0.05),观察组与对照组低钾血症发生率分别为42.11%、15.79%,观察组与对照组感染率分别为73.68%、94.74%。观察组患者的中位OS为13.13(1.67-53.63)个月,对照组患者的中位OS为16.60(0.57-59.67)个月。结论:维奈克拉联合去甲基化药物组发生治疗后骨髓抑制程度低,但恢复时间长,其缓解率不亚于“3+7”强化疗,且感染率更低,但是“3+7”强化疗方案组低钾血症发生率低,且该方案明显改善患者长期结局。
