Remark on approximation in the calculation of the primordial spectrum generated during inflation [PDF]
, 2000 We re-examine approximations in the analytical calculation of the primordial spectrum of cosmological perturbation produced during inflation. Taking two inflation models (chaotic inflation and natural inflation) as examples, we numerically verify the ...

Forecasting Inflation in a Data-Rich Environment: The Benefits of Machine Learning Methods
Journal of business & economic statistics, 2019 Inflation forecasting is an important but difficult task. Here, we explore advances in machine learning (ML) methods and the availability of new datasets to forecast U.S. inflation.

Frontiers in Astronomy and Space Sciences, 2018 The properties of the recently discovered Higgs boson together with the absence of new physics at collider experiments allows us to speculate about consistently extending the Standard Model of particle physics all the way up to the Planck scale.

Physical Review D, 1999 Inflationary solutions are constructed in a specific five-dimensional model with boundaries motivated by heterotic M-theory. We concentrate on the case where the vacuum energy is provided by potentials on those boundaries. It is pointed out that the presence of such potentials necessarily excites bulk Kaluza-Klein modes.

Molecular Oncology, EarlyView.Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

Identifying Universality in Warm Inflation
, 2018 Ideas borrowed from renormalization group are applied to warm inflation to characterize the inflationary epoch in terms of flows away from the de Sitter regime. In this framework different models of inflation fall into universality classes.

Remote Inflation: Hybrid-like inflation without hybrid-type potential [PDF]
, 2009 A new scenario of hybrid-like inflation is considered without using hybrid-type potential. Radiation raised continuously by a dissipating inflaton field keeps symmetry restoration in a remote sector, and the false-vacuum energy of the remote sector ...

The Relationship between Inflation and Inflation Uncertainty in the Short- and Long-run: State Space Models with Markov Regime Switching Heteroskedasticity [PDF]
فصلنامه پژوهشهای اقتصادی ایران, 2013 In this study by using Markov Regime Heteroscedasticity method (MRSH) In the form of state-space model the relationship between inflation and uncertainty of inflation in Iranian economics is examined.

Hybrid inflation followed by modular inflation
, 2007 Inflationary models with a superheavy scale F-term hybrid inflation followed by an intermediate scale modular inflation are considered. The restrictions on the power spectrum P_R of curvature perturbation and the spectral index n_s from the recent data ...
