Regularized-renormalized-resummed loop corrected power spectrum of non-singular bounce with Primordial Black Hole formation

European Physical Journal C: Particles and Fields
We present a complete and consistent exposition of the regularization, renormalization, and resummation procedures in the setup of having a contraction and then non-singular bounce followed by inflation with a sharp transition from slow-roll (SR) to ...

Optimal Generalized Quasi-Polycyclic Codes over ${\mathbb{F}}_{\mathit{q}}+\mathit{u}{\mathbb{F}}_{\mathit{q}}$

Mathematics
This paper develops a structural and constructive theory of right generalized quasi-polycyclic (GQPC) codes over the finite chain ring R=Fq+uFq with u2=0, extending the existing field-based GQPC framework to a ring-theoretic setting.

Dold-Kan Type Theorem for Γ-Groups

, 1998
Introduction \Gamma-spaces were introduced by Segal [S], who proved that they are combinatorial models for connective spectra (see also [A], [BF]). Based on Kan-Thurston theorem we show that any \Gamma-space is stably weak equivalent to a discrete \Gamma-

A characterization of prime Noetherian P. I. rings and a theorem of Mori-Nagata

, 1979
Let R be a noetherian prime p.i. ring, C the center of R and C ¯ \bar C its normalization. It is proved that R is integral over its center iff C ¯ \bar

Evaluating Forecasts at Multiple Horizons: An Extension of the Diebold–Mariano Approach

Journal of Forecasting, EarlyView.
ABSTRACT Forecast accuracy tests are fundamental tools for comparing competing predictive models. The widely used Diebold–Mariano (DM) test assesses whether differences in forecast errors are statistically significant. However, its standard form is limited to pairwise comparisons at a single forecast horizon.

Tokuyama’s Theorem

, 2011
This chapter introduces the Tokuyama's Theorem, first by writing the Weyl character formula and restating Schur polynomials, the values of the Whittaker function multiplied by the normalization constant.

Creation of a Landslide Susceptibility Map Using Short‐Term Data From the July 2018 Heavy Rainfall in Southern Hiroshima Prefecture

Geological Journal, EarlyView.
This work advances landslide susceptibility mapping by incorporating short‐term trigger data with landscape susceptibility mapping. We also examine the importance of downsampling, watershed delineation and geospatial correlations in evaluating outcomes.

Strong Normalization of a Typed Lambda Calculus for Intuitionistic Bounded Linear-time Temporal Logic

, 2015
Linear-time temporal logics (LTLs) are known to be useful for verifying concurrent systems, and a simple natural deduction framework for LTLs has been required to obtain a good computational interpretation.

Impact of Geography on Institutions in Agricultural and Nomadic Societies

International Studies of Economics, EarlyView.
ABSTRACT How geography affects the choice of institutions is studied in a theoretical model. In this model, nations are located around a circle. Rulers compete through choosing tax rates, the level of military spending, and the degree of formality of institutions. Geographic condition is captured by population density.
