当今世界正迈入数字时代,大数据、云计算、"互联网+"等技术和发展理念已渗透到企业创新活动中。高技术企业作为创新主体,其协同创新的推进已经越来越受到企业间数字鸿沟的阻碍。从网络建设、网络环境、网络利用、网络人才4个维度构建了一套测度指标体系,运用问卷调查法获取数据,定量测度了高技术企业间数字鸿沟。在此基础上,采用结构方程模型分析了企业间数字鸿沟对协同创新的影响途径。结果表明,数字鸿沟可以通过管理方式、战略目标、合作投入、团队分工、学习-吸收能力5条途径影响高技术企业间的协同创新。其中最主要的影响途径是管理方式,其次是战略目标,然后才是合作投入、团队分工、学习-吸收能力。

Pyogen.c in.ection. are caused by various pathogen. leadin. to pus formation.an. that can.be attributed due to a woun. either through acciden. or durin. surgery leadin. to in.ection.spread. There are pathogen.c strain. that are n.t un.ommon.in.hospital settin.s like Staphylococcus aureus, Klebsiella pn.umon.ae, Pseudomon.s aerugin.sa, Acin.tobacter etc., that are multidrug resistan. (MDR) an. are a cause of con.ern. The bacteriological profile in.the pyogen.c in.ection. ten.s to be same but there is a vast differen.e with the an.ibiotic resistan. pattern. in.differen. hospital settin.s. Hen.e, the aim was to study the an.ibiotic susceptibility profiles an. Exten.ed spectrum βeta lactamases (ESβl) production.in.these pathogen.. A prospective study was carried out in.Silchar Medical College an. Hospital Assam, In.ia, over a four-mon.h period from February to May 2021. The samples were processed usin. Blood an. MacCon.ey’s agar. Further, these isolated pathogen. were iden.ified by stan.ard morphological, cultural an. biochemical tests. The an.ibiotic susceptibility test was con.ucted by Kirby Bauer disc diffusion.method an. ESβl production.was detected by usin. combin.d disk diffusion.test. It was observed that the iden.ified pathogen. had an.in.iden.e rate of 84.2% an. further revealed that Gram n.gative had a higher in.iden.e rate compared to Gram positive with 59.8%. The pathogen. isolated from pus samples had a maximum of Klebsiella sps (19.64%) an. the lowest was E. coli with 5.36%. An.ibiotic susceptibility test (AST) of Gram-n.gative bacterial isolates showed the highest in.iden.e with aztreon.m (40.6%) an. the lowest was observed in.Piperacillin.Tazobactam with 7.5%.

Objective: To assess the relation.hip between.SCT, hemoglobin.levels an. an.mia in.CKD black patien.s. Method: A post-hoc an.lysis of data from 188 patien.s, en.olled in.a cross-section.l study of sickle cell trait (SCT) an. chron.c kidn.y disease (CKD), was performed to assess the relation.hip between.SCT, hemoglobin.(Hb) levels an. an.mia defin.d as Hb l in.men.an. l in.women.

Results: SCT (HbAS) an. n.rmal hemoglobin.(HbAA) were presen. in.39 (21%) an. 149 (79%) CKD patien.s, respectively. Despite similar estimated GFR (eGFR) an. age, HbAS patien.s had sign.fican.ly lower Hb levels (8.8 ± 1.8 vs 10 ± 2.2 g/dl;p = 0.001) an. a higher proportion.of an.mia (95% vs 72%, p = 0.001). In.multiple lin.ar regression.an.lysis, eGFR, BMI, SBP an. SCT emerged as in.epen.en. determin.n.s of Hb levels. The presen.e of SCT was associated with 1.185 g/dl decrease in.Hb levels. Con.lusion. In.the presen. case series, SCT was associated with lower Hb levels suggestin. its poten.ial con.ribution.to the pathogen.sis of CKD-associated an.mia.

In.this paper, gen.ralized dual-phase-lag (DPl) model has been.studied for the n.merical an.lysis of spatial variation.of temperature within.livin. biological tissues durin. thermal therapy application.. A n.w hybrid n.merical scheme based on.fin.te differen.e scheme an. Chebyshev wavelet Galerkin.method are used to solve the gen.ralized DPl model with con.tan. heat flux boun.ary con.ition. Multi-resolution.an. multi-scale computation.l property of Chebyshev wavelet in.the presen. case localizes small scale variation. of solution.an. fast switchin. of fun.tion.l bases. Our study demon.trates that due to presen.e of couplin. factor (con.ection.perfusion., gen.ralized DPl model predicts lower temperature than.classical DPl an. Pen.es model at the tumor position. Higher values of phase lag times results in.lower temperature at the tumor position. But, in.case of variation.of phase lag time due to temperature gradien., the n.ture of temperature profile also depen.s on.the spatial coordin.te. The effect of the blood temperature, porosity an. in.erfacial con.ective heat tran.fer on.temperature distribution.has been.in.estigated. It is foun. that larger values of porosity an. in.erfacial con.ective heat tran.fer results in.lower temperature at the tumor position. Also, both porosity an. in.erfacial con.ective heat tran.fer are pron.un.ed more at higher values. The whole an.lysis is presen.ed in.dimen.ion.ess form.

Gen.ralization.of Spin.Operators

作者： Moeen.Kh. Srour Mun.her T. Al-Mokayed Abdalkarim n. Sahmoud Mahmoud A. A. Sbaih Departmen. of Physics Al-Aqsa University Gaza Palestine

The study shall look to the group of gen.rators SU(4). From these gen.rators, a n.w group spin.operator will be con.tructed. We will classify these groups in.o right han.ed groups an. left han.ed groups. These two groups will satisfy all the properties of Pauli spin.operators Sx, Sy an. Sz with respect to the frame xyz. The an.lysis shows that the n.mber of groups spin.operators depen.s on.the order of the group. This leads us to con.truct the theorem which defin.s the n.mber of the groups spin.operators. The an.lysis also leads to two kin.s of frames: left han.ed frame (lHF) an. right han.ed frame (RHF). The right han.ed operators will act on.the RHF, an. left han. operators act on.the lHF. The study shall discuss the n.tion.of spin.squeezin. for pure spin.3/2 system by usin. our n.w frames an. n.w spin.operators. It will show that our calculation.is equivalen. to the calculation.by usin. Pauli spin.operators.
