Lithography simulation is key to the preparation of mask data and verification of mask patterns [1], which enhances design-to-wafer fidelity and minimizes distortions. However,the complexity of lithography simulation has tremendously increased with the decrease in feature size, prolonging the simulation cycle. Hence, an accurate and fast lithography simulation is in great demand.

Developing suitable anode materials for potassium-ion batteries(PIBs)remains a great challenge owing to the limited theoretical capacity of active materials and large radius of K+ion(1.38?).To solve these obstacles,by integrating the principles of multielectron transfer and rational porous crystal framework,we creatively propose the monoclinic Cu_(3)(OH)_(2)V_(2)O_(7)·2H_(2)O(CVO)as a novel anode for PIBs.Furthermore,inspired by the metastable nature of CVO under high temperature/pressure,we skillfully design a facile hydrothermal recrystallization strategy without the phase change and surfactants addition.Thus,for the first time,the porous composite of Cu_(3)(OH)_(2)V_(2)O_(7)·2H_(2)O nanobelts covered in situ by reduced graphene oxide(CVO NBs/r GO)was assembled,greatly improving the deficiencies of CVO.When used as a novel anode for PIBs,CVO NBs/r GO delivers large specific capacity(up to 551.4 m Ah g^(-1)at 50 m A g^(-1)),high-rate capability(215.3 m Ah g^(-1)at 2.5 A g^(-1))and super durability(203.6 m Ah g^(-1)at 500 m A g^(-1)even after 1000 cycles).The outstanding performance can be ascribed to the synergistic merits of desirable structural features of monoclinic CVO nanobelts and the highly conductive graphene 3D network,thus promoting the composite material stability and electrical/ionic conductivity.This work reveals a novel metal vanadate-based anode material for PIBs,would further motivate the subsequent batteries research on M_(3)(OH)_(2)V_(2)O_(7)-n H_(2)O(M;Co,Ni,Cu,Zn),and ultimately expands valuable fundamental understanding on designing other high-performance electrode materials,including the combined strategies of multielectron transfer with rational porous crystal framework,and the composite fabrication of 1D electrode nanostructure with conductive carbon matrix.

目的探究2型糖尿病(type 2 diabetes nephropathys,T2DM)合并肺结核患者空腹血糖(fasting plasma glucose,FPG)水平与痰涂片、结核分枝杆菌T细胞斑点实验(T-cell spot test for tuberculosis infection,T-SPOT.TB)结果的关系及结核分枝杆菌rpoB基因检测的临床意义。方法选取2022年1月—2023年1月昆明市第三人民医院收治102例T2DM合并肺结核患者作为研究组,另选同期在我院治疗的102例单纯肺结核患者作为对照组。比较2组临床资料、痰涂片和T-SPOT.TB检查结果,并对研究组不同FPG水平患者痰涂片阳性率、T-SPOT.TB阳性率进行比较,分析痰涂片阳性率、T-SPOT.TB阳性率与患者FPG水平的相关性。对2组进行结核分枝杆菌培养,分离利福平(rifampicin,RFP)耐药菌株和敏感菌株,比较2组2种菌株rpoB基因检测结果。结果研究组咳嗽、呼吸困难、厌食、盗汗、胸痛、咯血、发热发生率、痰涂片阳性率、T-SPOT.TB阳性率均高于对照组(P均<0.05)。不同FPG水平患者痰涂片阳性率比较,差异具有统计学意义(P=0.003);T-SPOT.TB阳性率比较,差异无统计学意义(P=0.262);痰涂片阳性率与T2DM合并肺结核患者FPG水平呈正相关(rs=0.386,P=0.015),T-SPOT.TB阳性率与FPG水平无明显相关性(rs=0.127,P=0.326)。研究组RFP耐药菌株多于对照组,研究组RFP耐药菌株rpoB基因突变率高于RFP敏感菌株(P均<0.05)。结论T2DM合并肺结核患者FPG水平与痰涂片结果呈正相关,但与T-SPOT.TB结果无相关性。与单纯肺结核患者相比,T2DM合并肺结核患者更易感染耐药株。通过检测耐药基因rpoB,可快速识别检测结核分枝杆菌对RFP耐药性,为临床治疗提供科学指导。

For the efficiency of image processing in traditional single-machine environment is low, and the image processing used Hadoop cluster has too large load of the main node. In this framework, the internal representation of images serialized in Hadoop and the image storage model named ImgBundleFile was designed, the OpenCV image processing library was introduced and the image processing interface using the Java development language was designed. In order to greatly shorten the image processing time of the framework, a MapTask load balancing strategy is proposed. Using framework for the face detection, experimental results show that the image parallel processing framework based on Hadoop has good stability and scalability, and the efficiency is significantly improved compared with the traditional single-machine environment.

In the face of intense global competition,the Chinese semiconductor industry grapples with unprecedented challenges.Addressing theissueeof“bottleneck technology”has become a paramount concern among experts from various domains in China.However,the trajectory of the global semiconductor sector is inexorably linked to the innovation of its business models and adherence to the tenets of technological evolution.It can be posited that,without business model innovation,Moore's Law would cease to exist.In the semiconductor arena,where the first-mover advantage wields immense influence,exclusive focus on“technological breakthroughs”froma technical standpoint would invariably constrict itself within existing technological paradigms,leaving it susceptible to external control.This paper undertakes an in-depth examination of pivotal case studies,particularly that of TSMC and Samsung,two enterprises which transcended1their latecomer status and shattered the“glass ceiling”by embracing“business model innovations.”Through a comprehensive analysis,it introduces and delineates two distinctive avenues of business model innovation:paper“reconstruction of the division of labor system”aand“mismatched demand.”Subsequently,tthe researchini vestigates two more cases,SiEn Integrated Circuits Co.,Ltd.and Changguangg Group,exploring specific business modelinnovation paths,“innovation consortium”and“differentiated demand,”pertinentto latecomer semiconductor companies operating in China.Drawing from these insightsand considering thecurrent international competitive landscape and the ramifications of the COVID-19 pandemic,this paper culminates in the synthesis of eight breakthrough trajectories for latecomer semiconductor firms.These pathways are examined through the lenses of technology paradigms(traditional and emerging),market contextss(globalized and deglobalized),and various types of business model innovation(original and secondary).Furthermore,this research offersa comprehensive analysis and discussion concerning the resources,capabiliti

采用分子动力学模拟计算方法,在10 MPa的压力条件下,对二氧化硫和乙烷水合物体系,分别在275、285、295、305 K等不同温度下的变化情况进行模拟研究。预测了二氧化硫、乙烷、水的扩散系数,探讨了密度、氢键数和配位数等结构性质。结果表明,水受到温度的影响较大,二氧化硫明显比乙烷更容易与水结合,乙烷被水和二氧化硫排挤而大量聚集,能够达到利用二氧化硫置换和收集乙烷的目的。
