The expansion dynamics of the universe in $f(Q)$ gravity is examined with the Gong-Zhang kind of dark energy equation of state parameter. By considering the $f(Q)$ gravity form $f(Q)=Q+ \alpha Q^{n}$, we obtain the Hubble parameters in terms of redshift $z$. Using Bayesian statistical methods based on the $\chi^{2}$ minimization methodology, we constrain the model parameters by using the supernovae Pantheon sample with cosmic chronometer sample. The evolution of equation of state parameter, energy density, pressure with the statefinder diagnostic are thoroughly investigated to examine the universe evolution in model. We have also obtained the universe's current age for these models. The considered models may exhibit either the quintom evolution or the future decelerating universe evolution., Comment: 20 pages, 16 figures

This study examines the radiative capture of a neutron by $^{10}$Be using the Coulomb dissociation approach within the FRDWBA theory. We analyze the elastic Coulomb breakup of $^{11}$Be on a $^{208}$Pb target at 72 MeV/A to determine the photodisintegration cross-section and radiative capture cross-section. Utilizing the Maxwell-averaged velocity distribution, we calculate the resulting radiative neutron capture reaction rate for the $^{10}$Be(n,$\gamma$)$^{11}$Be reaction. Comparative analyses are conducted with experimental data, theoretical results from direct radiative capture methods, and transfer reaction calculations. Additionally, we contrast our findings with the existing $^{10}$Be($\alpha$,$\gamma$)$^{14}$C reaction rate and conclude the dominance of neutron capture over $\alpha$ capture by $^{10}$Be., Comment: 20 pages, 5 figures, accepted for publication in The European Physical Journal Special Topics "Nuclear Astrophysics: Recent Progress in Understanding Element Formation in the Universe"

In this study, we construct a theoretical framework based on the generalized Hubble parameter form which may arise within the particle creation, viscous and $f(R)$ gravity theory. The Hubble parameter is scrutinized for its compatibility with the observational data relevant to the late-time universe. By using Bayesian statistical techniques based on $\chi^{2}$ minimization method, we determine model parameters's best fit values for the cosmic chronometer and supernovae Pantheon datasets. For the best fit values, the cosmographic and physical parameters are analyzed to understand the cosmic dynamics in model., Comment: 16 pages, 10 figures

While forming an ($A$+2) nucleus from a nucleus $A$ via a two-neutron transfer reaction, the constructive interference of the many possible reaction channels favors significant pairing enhancement through the continuum of the intermediate ($A$+1) nucleus [Phys. Lett. B \textbf{834} 137413 (2022)]. I analyse this situation in more generality, from the point of view of a varying pairing field and different continua leading to the formation of ($A$+2) nucleus. I consider $^6$He and $^{22}$C, described as housing two-neutrons in orbitals of $^5$He and $^{21}$C, respectively. The different possible situations manifest that the continuum correlations are extremely crucial to the extension of the pairing enhancement observed in the system., Comment: 11 pages, 6 figures

We calculate the $^{11}$B$(n,\gamma)^{12}$B reaction rate, an important constituent in nucleosynthesis networks, contributed by resonant as well as non-resonant capture. For the resonant rate, we use the narrow resonance approximation whereas the non-resonant contribution is calculated with the Coulomb dissociation method for which we use finite-range distorted wave Born approximation theory. We then compare our calculated rate of $^{11}$B$(n,\gamma)^{12}$B reaction with those reported earlier and with other charged particle reactions on $^{11}$B.

In this paper, we examine the universe's expansion in $ f(R, L_{m}) $ gravity for a particular form of $ f(R, L_{m})=\frac{R}{2}+L_{m}^{n}$. The field equations for flat FLRW metric with matter Lagrangian $ L_{m}=\rho$ are derive. Hubble parameter in terms of red-shift$(z)$ are derived using the linear form of Equation of State (EoS) parameter $ \omega=w_{0}+w_{1}z $. By using Bayesian statistical techniques based on $ \chi^{2}$-minimization technique, we have obtained the best fit values of the model parameters of this model for cosmic chronometer and supernovae Pantheon datasets. The evolution of the equation of state parameter$(\omega)$, energy density $ (\rho) $, pressure $\mathit{(p)}$ cosmographic parameters, and the impact of the energy conditions with best-fit values of the model parameters are all thoroughly examined. We have also analyze Om diagnostic's behavior and determine the present age of universe for this model., Comment: Accepted Manuscript, 27 pages, 13 figures

We aim to explore the bubble nature of the exotic nucleus $^{20}$N within the microscopic antisymmetrized molecular dynamics (AMD) approach. Constraining its structural parameters, we analyse its static properties. Subsequently, we use the AMD infused finite-range distorted-wave Born approximation theory to calculate the Coulomb breakup of $^{20}$N as an indirect approach to estimate the $^{19}$N$(n,\gamma)^{20}$N radiative capture rate., Comment: 8 pages, 4 figures

In the wake of the COVID-19 pandemic, World Health Organization (WHO) recommended the use of face-masks to combat the disease. A fraction of the population has been vocal about their disapproval, especially on social media. Motivated by the need to understand their opinions, an international online survey in English was shared to the community /r/SampleSize in Reddit. The results obtained were summarized; binomial and multinomial confidence intervals were constructed for variables of interest; Pearson's Chi-squared test was used to test whether relationship exists between two variables of interest. A second, smaller survey was conducted to cross-validate the results. The study demonstrates that despite the digital polarization of public opinion, opinions from both sides of the spectrum are not ubiquitous.
