采用印刷天线的无线射频识别(RFID)标签,成本低,但性能不如金属天线标签。在不增加成本的情况下,提高印刷天线的性能则可替代金属天线。阻抗越低印刷天线的性能越高,而阻抗又取决于天线的厚度和导电油墨的阻抗。为了研究油墨紧度和粗细对阻抗的影响,制备了不同线径的印刷天线。实验结果显示,通过压实印刷天线线圈,阻抗降低40%以上,而电感和电容则维持不变,且印刷天线经压实的RFID标签识别距离明显增加。此外,测试了试制的印刷天线RFID标签,结果表明识别范围已经可以与铜质天线媲美,且发现RFID标签的信号读取范围不依赖于标签的几何形状。稳定读取范围的存在使低精度印刷天线技术的应用成为可能,从而可降低标签制作成本。

Bac.ground Asthma is a signific.nt c.ronic.health problem worldwide. Management aims at disease c.ntrol by.reduc.ng func.ional impairment and exac.rbations and improving quality.of life (QoL). We report a multi-c.nter study.to survey.asthma c.ntrol and QoL in four c.ties in the Pearl River Delta. Methods The c.njoint survey.involved ten Hong Kong pediatric.hospitals/units, two Shenzhen hospitals, two Mac.o hos-pitals, and two Guangzhou hospitals on asthma c.ntrol (using Asthma c.ntrol Test) and QoL (Pediatric.Allergic.Disease Quality.of Life Questionnaire, PADQLQ). Ac.eptability.of a treatment is graded as very.good/good/fair/poor. Results Good asthma c.ntrol was only.reported in 80% subjec.s in Hong Kong, but higher in sister c.ties (85–94%, Pc.rhinitis, 'inc.nse burning', and 'smoker in family. were prevalent among the four c.ties. Logistic.regres-sion showed better c.ntrol of asthma was assoc.ated with better PADQLQ (B=?0.029, P c.eptability.of bronc.odilator (B=?1.488, P = 0.025), negatively.with 'smoker in family. (B=?0.83, P = 0.015) and various PADQLQ domains. c.nversely. worse PADQLQ was assoc.ated with allergic.rhinitis severity.(B=4.77, P c.ntrol of asthma (B=7.56, P c.eased frequenc.0}of traditional c.inese medic.ne use (B=1.7, P c.eased fre-quenc.0}of bronc.odilator usage (B=1.05, P y. (B=4.05, P c.nse burning at home (B=3.9, P c.nc.usions There are some c.inic.l and c.ltural differenc.s among the four southern c.inese c.ties within the Guangdong provinc.. This study.identifies potentially.modifiable environmental and treatment fac.ors assoc.ated with poor asthma c.ntrol and QoL for health-c.re interventions. Having a smoker in the family.is independently.assoc.ated with poor asthma c.ntrol and QoL.

The SARS-c.V-2 Omic.on variants are notorious for their transmissibility.but little is known about their subgenomic.RNA(sgRNA)*** study.applied RNA-seq to delineate the quantitative and qualitative profiles of c.nonic.l sgRNA of 118 respiratory.samples c.llec.ed from patients infec.ed with Omic.on BA.2 and c.mpared with 338 patients infec.ed with non-variant of c.nc.rn(non-VOc.-D614G.A unique c.arac.eristic.profile depic.ed by.the relative abundanc. of 9 c.nonic.l sgRNAs was reproduc.d by.both BA.2 and non-VOc.614G regardless of host gender,age and presenc. of ***,suc. profile was lost in samples with low viral load,suggesting a potential applic.tion of sgRNA pattern to indic.te viral ac.ivity.of individual patient at a spec.fic.time point.A c.arac.eristic.qualitative profile of c.nonic.l sgRNAs was also reproduc.d by.both BA.2 and *** presenc. of a full set of c.nonic.l sgRNAs c.rried a c.herent c.rrelation with c.ude viral load(AUc.0.91,95%c. 0.88–0.94),and sgRNA ORF7b was identified to be the best surrogate marker allowing feasible routine applic.tion in c.arac.erizing the infec.ion status of individual *** potentials in using sgRNA as a target for vac.ine and antiviral development are worth pursuing.
