The vis.ous.dis.ipation limit of weak s.lutions.is.cons.dered for the Navier-s.okes.equations.of compres.ible is.ntropic flows.confined in a bounded domain.We es.ablis. a Kato-type criterion for the validity of the invis.id limit for the weak s.lutions.of the Navier-s.okes.equations.in a function s.ace with the regularity index clos. to Ons.ger’s.critical thres.old.In particular,we prove that under s.ch a regularity as.umption,if the vis.ous.energy dis.ipation rate vanis.es.in a boundary layer of thicknes. in the order of the vis.os.ty,then the weak s.lutions.of the Navier-s.okes.equations.converge to a weak admis.ible s.lution of the Euler equations.Our approach is.bas.d on the commutator es.imates.and a s.btle foliation technique near the boundary of the domain.

s.rong evidence has.accumulated to s.ow a correlation between depres.ion s.mptoms.and inflammatory res.ons.s.Moreover,anti-inflammatory treatment has.s.own partial effectivenes. in alleviating depres.ion s.mptoms.Lycium barbarum polys.ccharide(LBP),derived from Goji berries.exhibits.notable antioxidative and anti-inflammatory properties.In our recent double-blinded randomized placebo-controlled trial,we found that LBP s.gnificantly reduced depres.ive s.mptoms.in adoles.ents.with s.bthres.old depres.ion.It is.pres.med that the antidepres.ant effect of LBP may be as.ociated with its.influence on inflammatory cytokines.In the double-blinded randomized controlled trial,we enrolled 29 adoles.ents.with s.bthres.old depres.ion and randomly divided them into an LBP group and a placebo group.In the LBP group,adoles.ents.were given 300 mg/d LBP.A 6-week follow up was.completed by 24 adoles.ents.compris.ng 14 adoles.ents.from the LBP group(15.36±2.06 years.3 men and 11 women)and 10 adoles.ents.from the placebo group(14.9±1.6 years.2 men and 8 women).Our res.lts.s.owed that after 6 weeks.of treatment,the interleukin-17A level in the LBP group was.lower than that in the placebo group.Network analys.s.s.owed that LBP reduced the correlations.and connectivity between inflammatory factors.which were as.ociated with the improvement in depres.ive s.mptoms.Thes. findings.s.gges. that 6-week adminis.ration of LBP s.ppres.es.the immune res.ons. by reducing interleukin-17A level,thereby exerting an antidepres.ant effect.

The Nutri-s.ore is.a 5-color front-of-pack nutrition label des.gned to provide cons.mers.with an eas.ly unders.andable guideline to the healthines. of food products.The impact that the Nutri-s.ore may have on cons.mers.choices.is.unclear s.nce different experimental paradigms.have found vas.ly different effect s.zes.In the pres.nt s.udy,we have inves.igated how s.udent participants.change a hypothetical pers.nal 1-daydietary plan after a learning phas. during which they learn about the Nutri-s.ores.of the available food items.Participants.were ins.ructed to compos. a healthy diet plan in order that the ques.ion of whether the Nutris.ore would improve their ability to compos. a healthy dietary plan could be inves.igated,independent of the ques.ion of whether they would apply this.knowledge in their ordinary lives.We found a s.bs.antial(Cohen's.d=0.86)pos.tive impact on nutritional quality(as.meas.red by the Nutrient Profiling s.s.em s.ore of the Food s.andards.Agency)and a medium-s.zed(Cohen's.d=0.43)reduction of energy content.Energy content reduction was.larger for participants.who had initially compos.d plans.with higher energy content.The res.lts.s.gges. that the Nutri-s.ore has.the potential to guide cons.mers.to healthier food choices.It remains.unclear,however,whether this.potential will be reflected in real-life dietary choices.

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.

One of the crucial is.ues.in the chemical looping technology lies.in its.bed material:the oxygen carrier.Particle s.ze analys.s.of an oxygen carrier is.important s.nce in a fluidized bed the material can only work well within a s.ecific s.ze range.While the favorable s.ze ranges.for oxygen carrier materials.have already been reported,none of the publis.ed s.udies.has.analyzed the particle s.ze and s.ape of oxygen carriers.in detail.Furthermore,the effect of oxygen carriers.oxidation degree on s.ch properties.has.not been cons.dered either.This.s.udy aimed to report the particle s.ze and s.ape analys.s.of five iron-bas.d oxygen carriers.one natural ore,one s.nthetic material,and three res.due products.at different oxidation degrees.us.ng dynamic image analys.s.DIA).The oxygen carriers.were prepared at different mas. convers.on degrees.in a fluidized bed batch reactor.The s.ze dis.ribution,s.hericity,and as.ect ratio of the oxygen carrier particles.were examined experimentally us.ng a Cams.zer ins.rument.Our res.lts.s.ow that the DIA method was.s.cces.fully able to analyze the particle s.ze and s.ape of our oxygen carriers.with s.tis.ying accuracy for comparis.n.The oxidation s.ate of the inves.igated materials.s.ems.to only affect the particle s.ze and s.ape of oxygen carriers.to a minor extent.However,expos.res.to redox cycles.in a fluidized bed reactor may alter the particle s.ze and s.ape of mos. oxygen carriers.

Fault movement during earthquakes.is.a geotechnical phenomenon threatening buried pipelines.and with the potential to caus. s.vere damage to critical infras.ructures.Therefore,effective prediction of pipe dis.lacement is.crucial for preventive management s.rategies.This.s.udy aims.to develop a fas.,hybrid model for predicting vertical dis.lacement of pipe networks.when they experience faulting.In this.s.udy,the complex behavior of s.il and a buried pipeline s.s.em s.bjected to a normal fault is.analyzed by us.ng an artificial neural network(ANN)to generate predictions.the behavior of the s.il when different parameters.of it are changed.For this.purpos.,a finite element model is.developed for a pipeline s.bjected to normal fault dis.lacements.The data bank us.d for training the ANN includes.all the critical s.il parameters.cohes.on,internal friction angle,Young’s.modulus.and faulting).Furthermore,a mathematical formula is.pres.nted,bas.d on bias.s.and weights.of the ANN model.Experimental res.lts.s.ow that the maximum error of the pres.nted formula is.2.03%,which makes.the propos.d technique efficiently predict the vertical dis.lacement of buried pipelines.and hence,helps.to optimize the upcoming pipeline projects.
