We exp.ore the variable generalized Chap.ygin gas（VGCG） model in the theory of matter creation cosmology within the framework of a sp.tially homogeneous and isotrop.c flat Friedmann—Lemai tre—Robertson—Walker sp.ce-time. Matter creation cosmology is based on reinterp.etation of the energy–momentum tensor in Einstein's field equations. This creation corresp.nds to an irreversible energy flow from the gravitational field to the created matter constituents. The variable Chap.ygin gas（VCG） is also studied as a p.rticular solution. We use the Markov chain Monte Carlo method to constrain the free p.rameters of three models, namely,Lambda-Cold-Dark matter（ΛCDM）, VGCG and VCG models with and without matter creation from the latest observational data from baryon acoustic oscillations, cosmic chronometer, typ. Ia sup.rnovae（p.ntheon） including gamma-ray bursts, quasars and the local measurement of H0from R21 data. Two different combinations of dataset p.ovide a fairly tight constraint on the p.rameters of the ΛCDM, VGCG and VCG models. The p.esent values of various cosmological p.rameters are obtained, which are very close to the ΛCDM model. Furthermore, we p.rform stability analysis, Bayesian evidence analysis and information criteria analysis for these models through studying the sound sp.ed, Bayes factor, and Akaike information criteria（AIC） and Bayesian information criteria（BIC） selection criteria. The values of sound sp.ed for VGCG and VCG models shows that both the models are stable. According to AIC, it is observed that VGCG and VCG models with matter creation are sup.orted considerably less by current observations,while BIC shows that these models are not favoured by observational data.

In recent years, stem cells have been a focal p.int in research designed to evaluate the efficacy of op.thalmologic therap.es, sp.cifically those for corneal conditions. The corneal ep.thelium is one of the few regions of the body that maintains itself using a residual stem cell p.p.lation within the adjacent limbus. Stem cell movement has additionally cap.ivated the minds of researchers due to its p.tential ap.lication in different body regions. The cornea is a viable model for varying methods to track stem cell migratory p.tterns, such as lineage tracing and live imaging from the limbus. These develop.ents have the p.tential to p.ve the way for future therap.es designed to ensure the continuous regeneration of the corneal ep.thelium following injury via the limbal stem cell niche. This literature review aims to analyze the various methods of imaging used to understand the limbal stem cell niche and p.ssible future directions that might be useful to consider for the better treatment and p.evention of disorders of the cornea and corneal ep.thelium. .

Millets are widely recognized for their nutritional significance;however, the methods emp.oyed for their p.ocessing are currently lacking. This article p.imarily focuses on the advanced technologies and p.ogressions in millet dehulling and p.lishing. These technologies op.rate based on the fundamental p.incip.es of comp.ession-shearing, abrasion-friction, and centrifugal-imp.ct forces. p.ocessing of millets can be challenging because of the p.ysical characteristics and tight attachment of hull and bran to the endosp.rm. However, several dehullers have been designed to solve this p.oblem for different kinds of millets. In addition, the nutritional and anti-nutritional characteristics undergo alterations due to both dehulling and p.lishing p.ocesses. These alterations are thoroughly examined and discussed in this article. Sp.cifically, anti-nutrients such 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.lishing. The nutritional p.op.rties are also subjected to a reduction;however, this reduction can be mitigated by subjecting the grains to certain p.etreatments before dehulling and p.lishing. These treatments serve to enhance dehulling efficiency and nutrient digestibility while simultaneously reducing the p.esence of anti-nutrients. Novel thermal and non-thermal methodologies such as microwave, hydrothermal, high-p.essure p.ocessing, and ohmic heating can be emp.oyed for p.ocessing millets, thereby diminishing the loss of nutrients. Additional research can be carried out to investigate their imp.ct on the dehulling and p.lishing of millets.
