Self-gravitating fluid flows with Gowdy symmetry near cosmological singularities

open access: yes, 2017
We consider self-gravitating fluids in cosmological spacetimes with Gowdy symmetry on the torus $T^3$ and, in this class, we solve the singular initial value problem for the Einstein-Euler system of general relativity, when an initial data set is ...

Item factor analysis with target rotation for the one hundred and twenty items of the Yatabe Guilford Personality Inventory [PDF]

open access: yes, 2020
The Yatabe Guilford Personality Inventory was developed for measuring the twelve traits of personality (Tsujioka, 1957). Although ten items for each trait were selected using the item analysis method (item-total correlation), some researchers have ...

Langevin dynamics of the glass forming polymer melt: fluctuations around the random phase approximation

open access: yes, 1997
In this paper the Martin-Siggia-Rose (MSR) functional integral representation is used for the study of the Langevin dynamics of a polymer melt in terms of collective variables: mass density and response field density. The resulting generating functional (

Spillovers across the crude oil and major currencies exchange rates using dynamic-quantile-frequency analysis

open access: yesInternational Review of Economics & Finance
This study examines the link between the daily price changes of WTI and major global currencies from 2000 to 2022. It utilizes mixed dynamic-frequency-quantile-based models to provide new insights into their interconnectedness.

Structure of Lanczos-Lovelock Lagrangians in Critical Dimensions

open access: yes, 2010
The Lanczos-Lovelock models of gravity constitute the most general theories of gravity in D dimensions which satisfy (a) the principle of of equivalence, (b) the principle of general co-variance, and (c) have field equations involving derivatives of the ...

BPS Partition Functions for Quiver Gauge Theories: Counting Fermionic Operators

open access: yes, 2007
We discuss a general procedure to obtain 1/2 BPS partition functions for generic N=1 quiver gauge theories. These functions count the gauge invariant operators (bosonic and fermionic), charged under all the global symmetries (mesonic and baryonic), in ...
