On the two-loop contributions to the pion mass [PDF]
, 2007 We derive a simplified representation for the pion mass to two loops in three-flavour chiral perturbation theory. For this purpose, we first determine the reduced expressions for the tensorial two-loop 2-point sunset integrals arising in chiral ...

Analytic representation of $F_K/F_π$ in two loop chiral perturbation theory [PDF]
Phys. Rev. D 97, 091502 (2018), 2017 We present an analytic representation of $F_K/F_\pi$ as calculated in three-flavour two-loop chiral perturbation theory, which involves expressing three mass scale sunsets in terms of Kamp\'e de F\'eriet series. We demonstrate how approximations may be made to obtain relatively compact analytic representations. An illustrative set of fits using lattice

An Analysis of Protein Crystals Grown under Microgravity Conditions
CrystalsMicrogravity has been shown to be an excellent tool for protein crystal formation. A retrospective analysis of all publicly available crystallization data, including many that have not yet been published, clearly demonstrates the value of the ...

Lottery Ticket Search on Untrained Models with Applied Lottery Sample Selection
Machine Learning and Knowledge Extraction, 2023 In this paper, we present a new approach to improve tabular datasets by applying the lottery ticket hypothesis to tabular neural networks. Prior approaches were required to train the original large-sized model to find these lottery tickets. In this paper

Numerical evaluation of a two loop diagram in the cutoff regularization [PDF]
, 2003 The sunset diagram of $\lambda\phi^4$ theory is evaluated numerically in cutoff scheme and a nonzero finite term (in accordance with dimensional regularization (DR) result) is found in contrast to published calculations. This finding dramatically reduces

Nature, 1884 I NOTE in NATURE of July 3 (p. 229) an abstract of a communication of M. Gay to the Paris Academy of Sciences, made on June 23, in which he suggests a connection between the red sunsets and the frequent rains. During the latter half of the past winter the rains were incessant in the Atlantic States of America, and the writer suggested that they were ...

Hypergeometric resummation of self-consistent sunset diagrams for electron-boson quantum many-body systems out of equilibrium [PDF]
, 2015 A newly developed hypergeometric resummation technique [H. Mera et al., Phys. Rev. Lett. 115, 143001 (2015)] provides an easy-to-use recipe to obtain conserving approximations within the self-consistent nonequilibrium many-body perturbation theory.
