Effects of physics beyond the standard model in the neutrino sector are conveniently incorporated through non-standard interaction parameters. Assuming new physics in the form of dimension-6 vector operators, a recent global analysis of neutrino oscillation data including results from COHERENT experiment suggests two favourable new physics scenarios. These are LMA-Light (with normal mass ordering) and LMA-Dark (with inverted mass ordering) sectors of parameters. In this work, we study the effects of new physics solutions on Leggett–Garg-type (LGtI) inequality which quantifies temporal correlations in the system along with flavour entropy and genuine tripartite entanglement which can be considered as measures of spatial correlations. We show that the violation of LGtI for $$\nu _{\mu }$$ ν μ energy around 3 GeV in the DUNE experimental set-up can not only be an indication of presence of new physics but such a new physics is expected to be in the form of LMA-Dark sector with inverted ordering. Further, we show that the LMA-Light solution, in general, decreases the values of all measures of quantum correlations in comparison to their SM predictions. On the other hand, the Dark solution can significantly enhance the values of these measures.

Non-local correlations in entangled systems are usually captured by measures such as Bell’s inequality violation. It was recently shown that in neutrino systems, a measure of non-local advantage of quantum coherence (NAQC) can be considered as a stronger measure of non-local correlations as compared to the Bell’s inequality violation. In this work, we analyze the effects of non standard interaction (NSI) on these measures in the context of two flavour neutrino oscillations for DUNE, MINOS, T2K, KamLAND, JUNO and Daya Bay experimental set-ups. We find that even in the presence of NSI, Bell’s inequality violation occurs in the entire energy range whereas the NAQC violation is observed only in some specific energy range justifying the more elementary feature of NAQC. Further, we find that NSI can enhance the violation of NAQC and Bell’s inequality parameter in the higher energy range of a given experimental set-up; these enhancements being maximal for the KamLAND experiment. However, the possible enhancement in the violation of the Bell’s inequality parameter over the standard model prediction can be up to 11% whereas for NAQC it is 7%. Thus although NAQC is a comparatively stronger witness of nonclassicality, it shows lesser sensitivity to NSI effects in comparison to the Bell’s inequality parameter.

Background: Dipeptidyl peptidase-4 (DPP-4) inhibitors are a new class of oral antidiabetic agents that increase endogenous levels of incretin hormones and lead to an increased insulin level and a reduced glucagon level in a glucose-dependent way. Gemigliptin, is a potent, selective, competitive, and long-acting DPP-4 inhibitor. The objective of our study was to evaluate the realworld efficacy and safety of gemigliptin. Materials and methods: A real-world prospective, observational, single-center study conducted in the Endocrinology Department, of a tertiary care hospital. 60 patients were included with 22 (36.7%) female patients. The treatment options consisted of uncontrolled metformin monotherapy, dual combination therapy, triple oral anti-hyperglycemic agents, metformin, and basal insulin combination. Weight, body mass index (BMI), fasting plasma glucose (FPG), 2 hours post postprandial glucose (PPG), HbA1c% were documented at baseline and followed up at 3 months. Results: The baseline HbA1c, FPG and PPG were 9.50 ± ± 2.24 %, 176.71 ± 67.076 mg/dL, 243.37 ± 93.97 mg/dl respectively. After 3 months of additional gemigliptin therapy, HbA1c, FPG, and PPG were significantly re-
