Somatic stem cells （SSCs）, being essential in maintaining homeostasis of normal tissue, replenish dying cells and regenerate damaged tissues for organism. On the other hand, with the self-renewed ability, SSCs are ideal cellular targets to be acquired in multiple mutations transforming SSCs to cancer stem cells （CSCs） which cause malignancies and even recurrence after cancer treatment if CSCs fail to be eradicated （1）.

We apply the notion of discrete supersymmetry based on matrix factorization to quantum systems consisting of coupled bosonic oscillators to construct isospectral bosonic quantum networks. By using the algebra that arises due to the indistinguishability of bosonic particles, we write down the Schr?dinger equations for these oscillators in the different boson-number sectors. By doing so, we obtain, for every partner quantum network, a system of coupled differential equations that can be emulated by classical light propagation in optical waveguide *** mathematical scheme allows us to build quasi-two-dimensional optical arrays that are either isospectral or share only a subset of their spectrum after deliberately omitting some chosen eigenstates from the spectrum. As an example, we use this technique(which we call bosonic discrete supersymmetry or BD-SUSY) to design two optical, silica-based waveguide arrays consisting of six and three elements, respectively, with overlapping eigenspectrum.

目的探讨表观扩散系数(ADC)值在宫颈癌评估中的潜在价值。方法共112例宫颈癌病人及67例正常对照者在治疗前行常规3.0TMR成像及扩散加权成像(DWI)。所有ADC值分别用b=0,600s/mm2和b=0,1000s/mm2进行计算。结果两组ADC图均显示子宫颈癌的ADC值显著低于正常宫颈。高/中分化(G1/2)和低分化(G3)肿瘤的ADC值之间、鳞状细胞癌和腺癌的ADC值之间、根治性子宫切除术后复发或转移和术后无瘤生存者的术前ADC之间差异均有统计学意义。当子宫颈癌按其他特征(FIGO、淋巴结是否转移、肿瘤大小和年龄段)进行分组时,两组ADC图差异均无统计学意义。结论 ADC值在子宫颈癌和正常宫颈的鉴别诊断中有很高的诊断准确率。尽管存在一些重叠,ADC值仍可预示宫颈癌的组织学类型和分级。G3级肿瘤和较低的ADC值预示预后较差。两组ADC图的诊断准确性相同。要点①DWI为子宫颈癌提供了新的信息。②ADC值可以鉴别宫颈癌和正常宫颈。③治疗前ADC值可以预测根治性子宫切除术病人的预后。④ADC值有助于预示子宫颈癌的组织学类型和分级。⑤G3级肿瘤和较低ADC值病人可以从术前放化疗中受益。

Galvanic, compatibility between graphite epoxy composite materials (GECM) and LY12CZ aluminum alloy was evaluated in different atmospheric corrosion environments and by laboratory electrochemical measurements. Open circuit potential electrochemical measurements showed a relatively large potential difference about 1 volt between the GECM and LY12CZ aluminum alloy, and this difference provided the driving force for galvanic corrosion of the LY12CZ aluminum alloy as an anode. Having been exposed for 1, 3 or 5 years in Beijing, Tuandao and Wanning station, GECM/LY12CZ couples showed significant losses of strength and elongation. Protective coatings and non-conductive barriers breaking the galvanic corrosion circuit were evaluated under the same atmospheric corrosive conditions. Epoxy primer paint, glass cloth barriers and LY12CZ anodizing were effective in galvanic corrosion control for GECM/LY12CZ couples.

A series of simulating experimental studies on the rheological behavior and its influential factors of aluminum alloy in continuous roll-casting process have been explored in this paper with a Gleeble-1500 Thermal-Mechanical Simulation Tester and a set of special clamp system. Relevant rheological rules in the process of coupling transient solidification and continuous deformation of roll-casting conditions are obtained. Experimental results indicate that four different characteristic stages exist in the whole rheological process, and relative constitutive models suitable for the given conditions of continuous roll casting process have been established through multivariable linear regression analysis of the experimental data.

TiC_(x)is an excellent composite strengthening particle and grain refiner for Al ***,the stability of TiC_(x)is poor when solute Si exists in Al alloy melts,which significantly depresses its strengthening and grain refining *** this work,the destabilization mechanisms of the TiC_(x)particles in Al-Si alloy melt with a composition of Al-7Si-7.5TiC were explored via experiments,first-principles calculations and thermodynamic *** experimental results show that Si atoms diffuse into TiC_(x)and Ti atoms are released into the Al melt to form a Ti-rich transition zone during the insulation of TiC_(x)in Al-Si melt,and the TiAlySiz and Al_(4)C_(3)phases are solidified in the Ti-rich zone and at Ti-rich zone/TiC_(x)interface,*** first principles calculations show that the low formation energy of C vacancies facilitates the rapid diffusion of Si atoms in TiC_(x),while the doping of Si atoms reduces the energy barrier of diffusion of Ti atoms in TiC_(x)and promotes the formation of Ti-rich *** thermodynamic calculations show that the wide crystallization temperature range of the destabilized product TiAlySiz phase is the key to continuous decomposition of TiC_(x)*** addition,the driving force of the main destabilization reaction of TiC_(x)in the Al-Si alloys is about 44 times higher than that in the Al alloys without Si *** indicates that the presence of solute Si remarkably promotes the subsequent decomposition process of TiC_(x)in the Al-Si alloy melts.
