In this study,we used thef(T) gravity framework with the energy-momentum tensor for a perfect fluid to derive key cosmological parameters,including the Hubble parameter H,deceleration parameter q and Statefinder diagnostics.Model parameters were optimized using an R^(2) test,resulting in β=1.312_(-0.014)^(+0.013),ξ=1.273_(-0.0071)^(+0.0065) and H_(0)=72.60_(-0.49)^(+0.50),with an R^(2) of 0.9527.Our model aligns closely with the ACDM model and shows good performance based on AIC and BIC criteria.Analyzing the q(z) curve revealed the transition from deceleration to acceleration in the universe's expansion.Additionally,we examined pressure,energy density,and equation of state parameter for two models,f(T)=λT and f(T)=T+βT^(2),both aligning well with observational data.The r-s and r-q diagnostics further confirm our model's consistency with ΛCDM,making it a strong alternative for explaining cosmic expansion.The evolution of Ω(z) shows strong consistency with the ΛCDM model,with the Om parameter approaching 0.3 at lower redshifts and parameter uncertainties highlighting the model's reliability. 展开更多

Candida albicans has ability to switch from yeast to hyphal form which is an important virulence factor. The objective of the research is to study the effect of Phenazine Methosulphate (PMS) on virulence factors and to study expression profile in yeast to hyphal form transition in C. albicans. Phenazine Methosulphate (PMS) acted as an inhibitor of yeast to hyphal form transition, adhesion and biofilm formation in C. albicans. RTPCR study demonstrated that PMS Modulate the expression of genes involved in Ras1-cAMP-Efg1 and Cek1-MAPK signal transduction pathways. Cell cycle of C. albicans was arrested at S phase on treatment of PMS. Hyphal suppressor genes like Tup1, Mig1 and Nrg1 were upregulated by PMS. Based on our data on expression of genes during yeast to hyphal form transition in presence and absence of PMS, we hypothesize that inhibition of hyphal formation may be due to the overexpression of negative regulators of hyphal growth. Targeting of hyphal specific genes involved in these pathways may be a promising strategy for anti-candida drug development. 展开更多

The topology of full Mesh has driven the Researchers in the field of wireless communication to claim that wireless mesh networks can be a significant change in the future of wireless communication. This paper presents a simulation process using Mesh routers which simulate wireless mesh network with multiple values to investigate its performance and how results can be optimized in such experience. During the process, we expand the area by assigning different values according to the number of routers needed for implementation. We create a proper centralized connectivity with more and less number of nodes using IEEE802.11a and g as a backbone and source of internet. We also study and observe its topology which provides multiple interfaces and paths between endpoints as well can control, self heal, configure and organizes itself. 展开更多
