Using e^(+)e^(−)annihilation data corresponding to an integrated luminosity of 2.93 fb^(−1)taken at the center-of-mass energy√s=3.773 GeV with the BESIII detector,a joint amplitude analysis is performed on the decays D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η).The fit fractions of individual components are obtained,and large interferences among the dominant components of the decays D^(0)→a_(1)(1260)π,D^(0)→π(1300)π,D^(0)→ρ(770)ρ(770),and D^(0)→2(ππ)_(S)are observed in both *** the obtained amplitude model,the CP-even fractions of D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η)are determined to be(75.2±1.1_(stat).±1.5_(syst.))%and(68.9±1.5_(stat).±2.4_(syst.))%,*** branching fractions of D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η)are measured to be(0.688±0.010_(stat.)±0.010_(syst.))%and(0.951±0.025_(stat.)±0.021_(syst.))%,*** amplitude analysis provides an important model for the binning strategy in measuring the strong phase parameters of D^(0)→4πwhen used to determine the CKM angleγ(ϕ_(3))via the B^(−)→DK^(−)decay.

Toughening additive manufactured Zr-based bulk metallic glass composites by martensite phase transformation

Additive manufacturing technology based on laser powder bed fusion(LPBF)offers a novel approach for fabricating bulk metallic glass(BMG)products without restriction in size and ***,the BMGs prepared by LPBF usually suffered from less plasticity and poorer fracture toughness as compared to their cast counterparts due to partial crystallization in heat-affected zones(HAZs).Since crystallization in HAZs is hard to avoid completely in LPBF BMGs,it is desirable to design a suitable alloy system,in which only ductile crystalline phase,instead of brittle intermetallics,is formed in *** unique structure could effectively increase the toughness/plasticity of the LPBF *** achieve this goal,a quaternary BMG system with a composition of Zr_(47.5)Cu_(45.5)Al_(5)Co_(2)is adopted and subjected to *** is found that nearly a single phase of B_(2)-ZrCu is precipitated in HAZs,while a fully amorphous phase is formed in molten pools(MPs).This B_(2)phase reinforced BMG composite exhibits excellent mechanical properties with enhanced plasticity and ***,it is easy to modulate the mechanical properties by altering the amount of the B_(2)phase via adjusting the laser energy ***,the best combination of strength,plasticity,and notch toughness is obtained in the BMG composite containing 27.4%B_(2)phase and 72.6%amorphous phase,which exhibits yield strength(σ_(s))of 1423 MPa,plastic strain(ε_(p))of 4.65%,and notch toughness(K_(q))of 53.9 MPa m 1/***,a notable strain-hardening is also *** improvement of plasticity/toughness and appearance of strain-hardening behavior are mainly due to the martensite phase transformation from the B_(2)phase to the Cm phase during plastic deformation(i.e.,the phase transformation-induced plasticity effect).The current work provides a guide for making advanced BMGs and BMG composites by additive manufacturing.

紫外光固化纳米压印是实现纳米结构批量复制的一种新技术．其特点是低成本和高分辨,而且可以达到极高的套刻精度．为了得到大面积图案的均匀复制,可用聚二甲基硅氧烷(PDMS)制备透光的压印软模板．其母版图案可由高分辨率电子束曝光和反应离子刻蚀的方法在硅片基底上获得,然后用浇注的方法将图案转移到PDMS上．本实验特别发展了紫外光固化纳米压印适用于软膜压印的双层膜图型转移技术．该双层膜由廉价的光胶和聚甲基丙烯酸甲脂(PMMA)构成．对光胶层的压印可用普通的光学曝光仪实现．然后再将图案用反应离子刻蚀的方法转移到PMMA层中．为了证明方案的可行性,在两种不同材料的半导体基片上压印了三角晶格的光子晶体和准晶结构的图案,并用剥离的方法将它们转移到金属薄膜上,最后成功地进行了硅片刻蚀实验．相信这一纳米制做方法对大面积纳米光子结构和光学集成芯片的制造是普遍适用的．

Purpose CMOS pixel sensor has become extremely attractive for future high-performance tracking *** has been proposed for the vertex detector at the Circular Electron Positron Collider,which will allow precision measurements of the properties of the Higgs *** meet the stringent requirements for low power consumption,it is necessary to optimize the pixel sensor diode geometry to reach a high charge-over-capacitance ratio that allows reduction in analog power *** Collection electrode size and footprint are two critical elements in sensor diode geometry and have deciding impacts on the charge collection performance.A prototype CMOS pixel sensor,named JadePix-1,has been developed with pixel sectors implemented with different electrode sizes and footprints,and its charge collection performance has been characterized with radioactive *** Charge-to-voltage conversion gains for pixel sectors under test have been calibrated with low-energy *** results have been obtained for equivalent noise charge(below 10e−),charge collection efficiency(around 40%),charge-over-capacitance ratio(above 0.015 V)and signal-to-noise ratio(higher than 55).Conclusion Small collection electrode size and large footprint are preferred to achieve high charge-over-capacitance ratio that promises low analog power *** studies on sensor performance before and after irradiation,combined with this work,will conclude the diode geometry optimization.

目的探讨血清Hsa_circ_0057362在糖尿病足溃疡(DFU)患者中的表达及其预测病情严重程度及预后的价值。方法为病例对照研究。回顾性选取2020年1月至2023年3月海南省第三人民医院收治的116例DFU患者作为DFU组,选择我院同期收治的90例单纯2型糖尿病(T2DM)患者作为T2DM组,另选择同期来我院体检的正常人群60名作为对照组。根据Wagner分级标准,116例DFU患者中1级25例、2~3级54例、4~5级37例。按DFU感染严重程分为1~2级55例(无或轻度感染),3~4级61例(中重度感染)。根据DFU患者6个月预后情况分为预后良好组(68例)和预后不良组(48例)。使用实时荧光聚合酶链反应技术检测Hsa_circ_0057362水平,化学发光免疫分析法检测降钙素原(PCT)水平,酶联免疫吸附法检测血清白细胞介素-6(IL-6)水平,采用方差分析、SNK-q检验和t检验比较血清各组IL-6、CRP及Hsa_circ_0057362水平的差异。应用二元logistic回归分析法分析DFU患者预后不良的影响因素。绘制受试者工作特征曲线(ROC)分析Hsa_circ_0057362、CRP及IL-6预测DFU患者预后不良的价值。采用Spearman相关分析法分析DFU患者血清Hsa_circ_0057362表达水平与感染分级和Wagner分级的相关性。结果DFU组和T2DM组血清PCT、IL-6及Hsa_circ_0057362水平均明显高于对照组,且DFU组高于T2DM组(P<0.05)。预后不良组DFU病程、Wagner分级、血肌酐、尿酸、PCT、IL-6及Hsa_circ_0057362水平均明显高于预后良好组(P<0.05)。3~4级感染DFU患者血清Hsa_circ_0057362表达水平明显高于1~2级(分别为4.36±2.08和3.25±1.57,P<0.001)。随着Wagner分级增加,DFU患者Hsa_circ_0057362表达水平逐渐升高(4~5级为4.95±2.37,2~3级为3.56±1.79,1级为2.70±0.95,P<0.001)。多因素logistic回归分析结果显示,PCT(OR=2.793,95%CI 1.966~7.104)、IL-6(OR=2.376,95%CI 1.584~5.710)及Hsa_circ_0057362(OR=3.106,95%CI 2.624~10.248)水平升高是DFU患者预后不良的影响因素(P<0.05)。ROC曲线显示,Hsa_circ_0057362≥3.80预测DFU患者预后不良的AUC最大(0.891,95%CI 0.828~0.953),灵敏度为88.4%,特异度为86.2%。Spearman相关分析结果显示,DFU患者血清Hsa_circ_0057362表达水平与Wagner分级呈正相关(r=0.782,P<0.001)。结论Hsa_circ_0057362在DFU患者中呈高表达,其水平升高与病情严重程度及预后不良有关,是预测DFU患者预后不良的有用指标。

设D为模4余0或1的负整数,令O=O_(D)为虚二次域K=q(√D)中判别式等于D的序.熟知Hilbert类多项式HD(x)是O的j不变量j_(D)=j(C/O)在K上的最小多项式.令n_(D)=(O_(q(j_(D))):Z[j_(D)])表示Z[j_(D)]在q(j_(D))的整数环O_(q(j_(D)))中的指数.设p为任意素数.如果p|n_(D),或者者p|D在K中惯性且n_(D)的p-进离散赋值v_(p)(n_(D))≤3,则本文完全确定了H_(D)(x)在多项式环F_(p)[x]中的因式分解.
