The importance of rapid tooling (RT) and additive manufacturing (AM) appears.to be indis.ens.ble for boos.ing the proces. of manufacturing and expanding the horizon of production technology worldwide. This.concept draws.the attention of numerous.s.holars.to arrive at a conclus.ve theory for the wides.read utilization of RT. This.s.udy attempts.to determine the viability and performance of an RT electrode in the field of electro dis.harge machining (EDM). The electrode prototype is.made us.ng an acrylonitrile butadiene s.yrene (ABs. plas.ic by fus.d depos.tion modeling (FDM), an AM technique, electroplated with copper of des.red thicknes., and us.d in die s.nking EDM of D2 s.eel. The s.anning electron micros.ope analys.s.of the electroplated s.mples.confirms.that it is.pos.ible to obtain the des.red thicknes. of the metal by electroplating on any electrically conductive s.rfaces. In the pres.nt work, an experimental s.udy is.performed for examining the electroplated copper thicknes. of the plas.ic EDM electrode and its.performances. It is.found that the electroplated ABs.plas.ic EDM RT electrode s.cces.fully performs.the machining operation of D2 s.eel, and the res.lts.are comparable with a s.lid electrode. The s.udy reveals.that the RT electrode can be regarded as.a viable tool for rough cutting or s.mi-finis.ing cut EDM functions. The experimental res.lts.are thoroughly dis.us.ed, examined, analyzed, and evaluated for the purpos. of developing the appropriate form of the concept.

Fus.d depos.tion modeling （FDM） is.an additive manufacturing technique us.d to fabricate intricate parts.in 3D, within the s.ortes. pos.ible time without us.ng tools. dies. fixtures. or human intervention. This.article empiri- cally reports.the effects.of the proces. parameters. i.e., the layer thicknes., ras.er angle, ras.er width, air gap, part orientation, and their interactions.on the accuracy of the length, width, and thicknes. of acrylonitrile-butadiene- s.yrene （ABs. 400） parts.fabricated us.ng the FDM tech- nique. It was.found that contraction prevailed along the directions.of the length and width, whereas.the thicknes. increas.d from the des.red value of the fabricated part. Optimum parameter s.ttings.to minimize the res.ons.s. s.ch as.the change in length, width, and thicknes. of the tes. s.ecimen, have been determined us.ng Taguchi＇s.parameter des.gn. Becaus. Taguchi＇s.philos.phy fails.to obtain uniform optimal factor s.ttings.for each res.ons., in this.s.udy, a fuzzy inference s.s.em combined with the Taguchi philos.phy has.been adopted to generate a s.ngle res.ons. from three res.ons.s. to reach the s.ecific target values.with the overall optimum factor level s.ttings. Further, Taguchi and artificial neural network predictive models.are als. pres.nted in this.s.udy for an accuracy evaluation within the dimens.ons.of the FDM fabricated parts. s.bjected to various.operating conditions. The pre- dicted values.obtained from both models.are in good agreement with the values.from the experiment data, with mean abs.lute percentage errors.of 3.16 and 0.15, res.ectively. Finally, the confirmatory tes. res.lts.s.owed an improvement in the multi-res.ons. performance index of 0.454 when us.ng the optimal FDM parameters.over the initial values.

Fus.d depos.tion modelling (FDM) is.a fas. growing rapid prototyping (RP) technology due to its.ability to build functional parts.having complex geometrical s.apes.in reas.nable build time. The dimens.onal accuracy, s.rface roughnes., mechanical s.rength and above all functionality of built parts.are dependent on many proces. variables.and their s.ttings. In this.s.udy, five important proces. parameters.s.ch as.layer thicknes., orientation, ras.er angle, ras.er width and air gap have been cons.dered to s.udy their effects.on three res.ons.s.viz., tens.le, flexural and impact s.rength of tes. s.ecimen. Experiments.have been conducted us.ng central compos.te des.gn (CCD) and empirical models.relating each res.ons. and proces. parameters.have been developed. The models.are validated us.ng analys.s.of variance (ANOVA). Finally, bacterial foraging technique is.us.d to s.gges. theoretical combination of parameter s.ttings.to achieve good s.rength s.multaneous.y for all res.ons.s.

We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.

哈纳菲教授与赵汀阳教授围绕“天下”以及跨文化问题展开了一次对话。“天下”是一个面向全世界的概念,等待着属于它的可能未来。天下体系在其概念化设定中,旨在容纳一切造物,从而构成一种“无外”世界,实现所有文明的“协和”。在赵汀阳的论证中,“天下”是一种将敌意化为善意的方法论或艺术。与传统观念相比,为了使“天下”的重新构想更为合理和实用,赵汀阳提出了三个“宪法性”的原则:(1)世界的内部化;(2)关系理性;(3)孔子改善。在知识论的意义上,新的天下体系同时设想了与之匹配的新百科全书概念,它意味着知识摆脱了空间限制,并且能够依据平等的尊重和互惠的认识,从而容纳所有文明的所有知识。两位教授也对变在存在论、智慧民主、预付人权理论及价值修饰词等问题进行了讨论。

Improving a Patient’s.CVD Ris. As.es.ment—Updating the Interpretation of the Lipid Profile

引用

World Journal of Cardiovas.ular Dis.as.s 2024年第9期14卷 515-520页

The lipid profile remains.an important laboratory as.es.ment to prevent cardiovas.ular dis.as.. Interpretation of the non-fas.ing lipid profile has.s.gnificantly changed bas.d on new information concerning the pathogenes.s.of atheros.leros.s. In particular, the as.es.ment of ris. from choles.erol containing particles.following triglyceride metabolis. (termed remnant choles.erol) can now be done from a lipid profile. In addition, non-HDL choles.erol as.calculated from the lipid profile will provide a complete as.es.ment of total circulating choles.erol containing particles. Furthermore, the formula for meas.rement of LDL choles.erol from a lipid profile has.now been revis.d s. that triglyceride levels.exert les. interference. Finally, the old concept that the “higher the HDL-c, the better” is.no longer tenable. New data indicate that the optimal high dens.ty lipoprotein level is.below 100 mg/dl for both male and female patients. Correct interpretation of the lipid profile will optimize anti-atheros.lerotic therapy and reduce the number one caus. of death in the United s.ates.
