“…It is noteworthy to mention here that our results coincide with the findings from the reconstructed quantum chromodynamics ghost model in f (T ) gravity [61] and the f (R, T ) theory [62]. We would like to emphasize that our results coincide with the latest theoretical observational data examined by Myrzakulov et al [59].…”

Diabetes and hypertension are non-communicable diseases. Diabetes is a significant cause of early death and debility globally. The objective of the present study is to find out the percentage incidence of diabetes and hypertension in young females of Lahore College for Women University Jail Road, Lahore. This cross-sectional study was conducted, January 2017 to June 2017. It was included 200 subjects. The average age of the population under study was 20 ± 0.17 years. About 4.5% (n=9) of the population was pre-diabetic and all were obese. While, 36% (n=73) of population was suffering from prehypertension and 5% (n=10) with hypertension. Among a total of 83 subjects with elevated systolic blood pressure (SBP), 41 were overweight and obese. According to diastolic blood pressure (DBP) 7% (n=14) of the population was suffering from pre-hypertension and 6% (n=12) with hypertension. 26 subjects had elevated diastolic blood pressure and among these, 20 subjects were overweight and obese. The whole population is divided among 4 groups according to the age groups. Body mass index was moreprevalent in the age group 25-27 years. It is stated that overweight and obesity are strongly associated with diabetes and hypertension. It was concluded that increased BMI was the main predictor of diabetes and hypertension. However no diabetic patient were found in population and the prevalence of pre-diabetic subjects were 4.5 % and according to SBP and DBP 5% and 6 % of the population were hypertensive.

“…This has been explored in previous studies [13,14]. As part of this approach, a version of GR called the symmetric teleparallel equivalent of GR (ST EGR) was suggested [15][16][17][18][19][20][21][22][23][24][25][26][27]. This model utilizes a non-metric connection for spacetime geometry, but with the constraint that the total curvature and torsion are both zero.…”

This article investigates the effects of Tree Level Higgs Potential on reheating in f (Q) gravity. We examine the formalism of tree level inflation in a modified f (Q) model, finding that the slow roll and e-folds number during inflation depend on the f (Q) model α parameter. Additionally, we calculate the reheating as a function of the decay rate, constraining the inflationary parameters and reheating temperature. Our study reveals that the Tree Level Higgs Potential influences the reheating temperature and decay rate. We conclude that increasing the decay rate energy leads to higher reheating temperature, and the chosen α parameter affects the reheating temperature curve. This research advances our understanding of the interplay between Tree Level Higgs inflation, matter production, and modified gravity in f (Q) gravity.

“…This recent class of modification of f (Q) gravity, has attracted a lot of interest in the literature. From its application to cosmology and astrophysics [34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52], to interesting cosmological phenomenology at the background level [39,44,48,50,[53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72]. Additionally, it can fit observations in a very satisfactory way, through its confrontation with various background and perturbation observational data [36,42,45,49,[73]…”

Motivated by the exciting features and a recent proposed general form of the function of non-metricity scalar Q, we investigate the cosmological implications in f (Q) gravity, through the resulting effective dark energy sector, extracting analytical expressions for the dark energy density, equation-of-state parameter and the deceleration parameters. We show that even in the absence of a cosmological constant, the universe exhibits the usual thermal history, with the sequence of matter and dark energy eras, and the dark-energy equation-of-state parameter always lie in the phantom regime. Additionally, calculating the age of the universe, through the extracted analytical equations of the scenario at hand, we show that the result coincide with the value corresponding to ΛCDM scenario within 1σ. Moreover, we show the excellent agreement of the scenario at hand with Supernovae type Ia observational data. Lastly, comparing the cosmological behavior in the case of the absence of an explicit cosmological constant, with the one of the presence of a cosmological constant we show that f (Q) gravity can mimic the cosmological constant in a very efficient way, providing very similar behavior, revealing the advantages and capabilitites of the scenario at hand.
