s.ftware tes.ing is.a critical phas. due to m.s.onceptions.about am.iguities.in the requirem.nts.during s.ecification, which affect the tes.ing proces.. Therefore, it is.difficult to identify all faults.in s.ftware. As.requirem.nt changes.continuous.y, it increas.s.the irrelevancy and redundancy during tes.ing. Due to thes. challenges. fault detection capability decreas.s.and there aris.s.a need to im.rove the tes.ing proces., which is.bas.d on changes.in requirem.nts.s.ecification. In this.res.arch, we have developed a m.del to res.lve tes.ing challenges.through requirem.nt prioritization and prediction in an agile-bas.d environm.nt. The res.arch objective is.to identify the m.s. relevant and m.aningful requirem.nts.through s.m.ntic analys.s.for correct change analys.s. Then com.ute the s.m.larity of requirem.nts.through cas.-bas.d reas.ning, which predicted the requirem.nts.for reus. and res.ricted to error-bas.d requirem.nts. Afterward, the apriori algorithm.m.pped out requirem.nt frequency to s.lect relevant tes. cas.s.bas.d on frequently reus.d or not reus.d tes. cas.s.to increas. the fault detection rate. Furtherm.re, the propos.d m.del was.evaluated by conducting experim.nts. The res.lts.s.owed that requirem.nt redundancy and irrelevancy im.roved due to s.m.ntic analys.s. which correctly predicted the requirem.nts. increas.ng the fault detection rate and res.lting in high us.r s.tis.action. The predicted requirem.nts.are m.pped into tes. cas.s. increas.ng the fault detection rate after changes.to achieve higher us.r s.tis.action. Therefore, the m.del im.roves.the redundancy and irrelevancy of requirem.nts.by m.re than 90% com.ared to other clus.ering m.thods.and the analytical hierarchical proces., achieving an 80% fault detection rate at an earlier s.age. Hence, it provides.guidelines.for practitioners.and res.archers.in the m.dern era. In the future, we will provide the working prototype of this.m.del for proof of concept.

Ferroelectric HfO2 has.attracted m.ch attention owing to its.s.perior ferroelectricity at an ultra-thin thicknes. and good com.atibility with s.-bas.d com.lem.ntary m.tal-oxide-s.m.conductor (Cm.s. technology. However, the crys.allization of polar orthorhom.ic phas. (o-phas.) HfO2 is.les. com.etitive, which greatly lim.ts.the ferroelectricity of the as.obtained ferroelectric HfO2 thin film.. Fortunately, the crys.allization of o-phas. HfO2 can be therm.dynam.cally m.dulated via interfacial s.res. engineering. In this.paper, the growth of im.roved ferroelectric Al doped HfO2 (HfO2:Al) thin film. on (111)-oriented s. s.bs.rate has.been reported. s.ructural analys.s.has.s.gges.ed that nonpolar m.noclinic HfO2:Al grown on (111)-oriented s. s.bs.rate s.ffered from.a s.rong com.res.ive s.rain, which prom.ted the crys.allization of (111)-oriented o-phas. HfO2 in the as.grown HfO2:Al thin film.. In addition, the in-plane lattice of (111)-oriented s. s.bs.rate m.tches.well with that of (111)-oriented o-phas. HfO2, which further therm.lly s.abilizes.the o-phas. HfO2. Accordingly, an im.roved ferroelectricity with a rem.ant polarization (2P(r)) of 26.7 m. C/cm.2) has.been obtained. The res.lts.s.own in this.work provide a s.m.le way toward the preparation of im.roved ferroelectric HfO2 thin film..

Breas. cancer is.a type of cancer res.ons.ble for higher m.rtality rates.am.ng wom.n. The cruelty of breas. cancer always.requires.a prom.s.ng approach for its.earlier detection.

s.ybean is.a broadly popular and extens.vely cultivated crop, however, m.ny high-yield and high-quality varieties.require s.ecific growth conditions. res.ricting their wides.read adoption. The appropriate light conditions.and photoperiod m.s. be attained for thes. varieties.to thrive in new environm.nts. In this.s.udy, we em.loyed CRIs.R/Cas. to des.gn two s.RNAs.aim.d at knocking out the m.turity-related gene E4 in a m.jor Am.rican s.ybean variety called ''Jack'', which belongs.to m.turity group m.II. E4 gene is.prim.rily involved in the photoperiodic flowering and m.turity in s.ybean, m.king it an ideal candidate for genetic m.nipulation. We s.cces.fully obtained 1 hom.zygous.E4-s.1 m.tant type with 1-bp ins.rtion, and 4 hom.zygous.E4-s.2 m.tants.type with 2-bp deletion, 7-bp deletion, 61-bp deletion, and 1-bp ins.rtion, res.ectively. The hom.zygous.e4 m.tant plants.contained early term.nation codons.devoid of trans.enic elem.nts. Additionally, no potential off-target s.tes.of the E4 gene were detected. A com.arative analys.s.revealed that, unlike the wild-type, the m.turity tim. of hom.zygous.e4 m.tants.was.early under both s.ort-day and long-day conditions. Thes. m.tants.offer novel germ.las.0}res.urces.that m.y be us.d to m.dify the photoperiod s.ns.tivity and m.turity of s.ybean, enhancing its.adaptability to high-latitude regions. © 2024 the Oil Crop Res.arch Ins.itute, Chines.
