We introduce a one-step implicit iterative method for two finite families of asymptotically nonexpansive mappings in a hyperbolic space and use it to approximate common fixed points of these families. The results presented in this paper are new in the setting of hyperbolic spaces. On top, these are generalizations of several results in literature from Banach spaces to hyperbolic spaces. At the end of the paper, we give an example to validate our results.

The diagnosis of non-alcoholic fatty liver disease(NAFLD)and metabolic dysfunction-associated fatty liver disease only on the basis of laboratory parameter score such as Hepatic Steatosis Index which includes liver enzymes,gender,basal metabolic index,and presence of diabetic mellitus is not sufficient to exclude other causes of deranged liver enzymes especially medications and autoimmune related liver *** the guideline suggests ultrasound is the preferred first-line diagnostic procedure for imaging of NAFLD,as it provides additional diagnostic information and the combination of biomarkers/scores and transient elastography might confer additional diagnostic accuracy and evident from previous similar studies too.

This article proposes a new transceiver design for Single carrier frequency division multiple access(SCFDMA)system based on discrete wavelet transform(DWT). SCFDMA offers almost same structure as Orthogonal frequency division multiple access(OFDMA)with extra advantage of low Peak to Average Power Ratio(PAPR). Moreover,this article also suggests the application of Walsh Hadamard transform(WHT)for linear precoding(LP)to improve the PAPR performance of the system. Supremacy of the proposed transceiver over conventional Fast Fourier transform(FFT)based SCFDMA is shown through simulated results in terms of PAPR,spectral efficiency(SE)and bit error rate(BER).

Mango peel is an important agro-industrial waste that has high levels of polyphenols and dietary fiber. There is an obvious shortage of product variety in the food sector, making research into new product creation even more important. Nowadays, only mango pulp is utilized in commercial items, resulting in the loss of the fruit's other components, which contain important chemicals. Numerous investigations on the extraction of bioactive components from mango peel have been undertaken, covering both classic techniques (direct boiling, solvent macerating, distillation, and compression) and green extraction technology (ultrasound-assisted, enzymeassisted, and ultrasound-assisted enzyme technique). Several approaches may be used to extract carotenoids, dietary fiber, and phenolic compounds. Dietary fiber and polyphenol intake have been linked to improved gut health. Polyphenol bioactivity and the risk of metabolic disorders may be affected by gut microbiota. The gut microbiota is vital for human health because it affects many host defensive mechanisms by enhancing antioxidant activity, tripling lactic acid bacteria, and assisting in the production of a superior prebiotic product. This review provides an overview of the high-quality extraction of dietary fiber and polyphenols from mango peel and also the interactions of these dietary compounds with gut microflora and associated health benefits and underlying mechanisms.
