We forecast the constraints on single-field inflation from bispectrum of future high-redshift surveys such as MegaMapper. Considering non-local primordial non-Gaussianity (NLPNG), we find that current methods will yield order σ(fNLeq)≈23, σ(fNLorth)≈12 in a joint power-spectrum and analysis, varying both nuisance parameters cosmology, including conservative range scales. Fixing cosmological qua...

Using a data sample of (1310.6±7.0)×106 J/ψ events taken with the BESIII detector at center-of-mass energy 3.097 GeV, we search for first time lepton number violating decay Σ−→pe−e− and rare inclusive Σ−→Σ+X, where X denotes any possible particle combination. The Σ− candidates are tagged in J/ψ→Σ¯(1385)+Σ− decays. No signal found, upper limits on branching fractions 90% confidence level determi...

In this study, the notion of isotopy generalized Bol loop is characterized. A isotope a σ-generalized shown to be σ’-generalized if σ’ fixes its (isotope) identity element where some conjugate σ. and only image isotope’s under right nuclear (where σ). It that can constructed using group subgroup it. conjugacy closed central loop.

In this research, Quantum-mechanical calculations were performed at the HF method with the 6-31+G*basis set and at the B3LYP method with the 6-31+G* basis set in the gas phase and five solvents such as water, DMSO, methanol, ethanol and dichloromethane at six temperatures. According to these theoretical results of IR, we extracted thermo chemical parameters such as enthalpy (∆H Kcal/mol), Gibbs...

in this research at the first enalapril drug and its fullerene derivative were optimized. nbo calculations and nmr for the complexes were carried out at the b3lyp/6-31g* quantum chemistry level. different parameters such as energy levels, the amount of chemical shift in different atoms, the amount of homo/lumo, chemical potential (µ ), chemical hardness (η), the coefficients of hybrid bonds (π,...

Wing rock phenomenon is an undesired motion appears in high angles of attack where a rolling in the aircraft in positive and negative roll angles with specified amplitude and frequency is occurred. In this paper two adaptive controllers suggested to control the rolling dynamics under wing rock phenomenon for a delta wing aircraft with presence of disturbance. Disturbance was considered as unmat...
