We exp.ore the variable generalized Chap.ygin gas.VGCG） model in the theory of matter creation cos.ology within the framework of a s.atially homogeneous.and is.trop.c flat Friedmann—Lemai tre—Roberts.n—Walker s.ace-time. Matter creation cos.ology is.bas.d on reinterp.etation of the energy–momentum tens.r in Eins.ein's.field equations. This.creation corres.onds.to an irrevers.ble energy flow from the gravitational field to the created matter cons.ituents. The variable Chap.ygin gas.VCG） is.als. s.udied as.a p.rticular s.lution. We us. the Markov chain Monte Carlo method to cons.rain the free p.rameters.of three models. namely,Lambda-Cold-Dark matter（ΛCDM）, VGCG and VCG models.with and without matter creation from the lates. obs.rvational data from baryon acous.ic os.illations. cos.ic chronometer, typ. Ia s.p.rnovae（p.ntheon） including gamma-ray burs.s. quas.rs.and the local meas.rement of H0from R21 data. Two different combinations.of datas.t p.ovide a fairly tight cons.raint on the p.rameters.of the ΛCDM, VGCG and VCG models. The p.es.nt values.of various.cos.ological p.rameters.are obtained, which are very clos. to the ΛCDM model. Furthermore, we p.rform s.ability analys.s. Bayes.an evidence analys.s.and information criteria analys.s.for thes. models.through s.udying the s.und s.eed, Bayes.factor, and Akaike information criteria（AIC） and Bayes.an information criteria（BIC） s.lection criteria. The values.of s.und s.eed for VGCG and VCG models.s.ows.that both the models.are s.able. According to AIC, it is.obs.rved that VGCG and VCG models.with matter creation are s.p.orted cons.derably les. by current obs.rvations.while BIC s.ows.that thes. models.are not favoured by obs.rvational data.

In recent years. s.em cells.have been a focal p.int in res.arch des.gned to evaluate the efficacy of op.thalmologic therap.es. s.ecifically thos. for corneal conditions. The corneal ep.thelium is.one of the few regions.of the body that maintains.its.lf us.ng a res.dual s.em cell p.p.lation within the adjacent limbus. s.em cell movement has.additionally cap.ivated the minds.of res.archers.due to its.p.tential ap.lication in different body regions. The cornea is.a viable model for varying methods.to track s.em cell migratory p.tterns. s.ch as.lineage tracing and live imaging from the limbus. Thes. develop.ents.have the p.tential to p.ve the way for future therap.es.des.gned to ens.re the continuous.regeneration of the corneal ep.thelium following injury via the limbal s.em cell niche.

Millets.are widely recognized for their nutritional s.gnificance;however, the methods.emp.oyed for their p.oces.ing are currently lacking. This.article p.imarily focus.s.on the advanced technologies.and p.ogres.ions.in millet dehulling and p.lis.ing. Thes. technologies.op.rate bas.d on the fundamental p.incip.es.of comp.es.ion-s.earing, abras.on-friction, and centrifugal-imp.ct forces. p.oces.ing of millets.can be challenging becaus. of the p.ys.cal characteris.ics.and tight attachment of hull and bran to the endos.erm. However, s.veral dehullers.have been des.gned to s.lve this.p.oblem for different kinds.of millets. In addition, the nutritional and anti-nutritional characteris.ics.undergo alterations.due to both dehulling and p.lis.ing p.oces.es. Thes. alterations.are thoroughly examined and dis.us.ed in this.article. s.ecifically, anti-nutrients.s.ch as.tannins.and p.ytate are p.edominantly found in the outer p.ricarp.of the grain and exp.rience a reduction after undergoing dehulling and p.lis.ing. The nutritional p.op.rties.are als. s.bjected to a reduction;however, this.reduction can be mitigated by s.bjecting the grains.to certain p.etreatments.before dehulling and p.lis.ing. Thes. treatments.s.rve to enhance dehulling efficiency and nutrient diges.ibility while s.multaneous.y reducing the p.es.nce of anti-nutrients. Novel thermal and non-thermal methodologies.s.ch as.microwave, hydrothermal, high-p.es.ure p.oces.ing, and ohmic heating can be emp.oyed for p.oces.ing millets. thereby diminis.ing the los. of nutrients. Additional res.arch can be carried out to inves.igate their imp.ct on the dehulling and p.lis.ing of millets.
