Analiza tedenske umrljivosti starostnikov: primerjava med Slovenijo in državami članicami EU27 (= Analysis of weekly mortality of seniors: a comparison between Slovenia and the member states of the EU27) [PDF]

Geodetski Vestnik, 2022
We analysed data on the weekly mortality of seniors aged 65 and older in the member states of the EU27. We aimed to model normal mortality in the time before covid-19 and use this model to analyse the deviations of true values from model predictions in ...

Jacobi sigma models

Journal of High Energy Physics, 2021
We introduce a two-dimensional sigma model associated with a Jacobi manifold. The model is a generalisation of a Poisson sigma model providing a topological open string theory.

Constraints on the generalized Chaplygin gas model including gamma-ray bursts via a Markov Chain Monte Carlo approach [PDF]

, 2011
We investigate observational constraints on the generalized Chaplygin gas (GCG) model including the gamma-ray bursts (GRBs) at high redshift obtained directly from the Union2 type Ia supernovae (SNe Ia) set.

Remarks on the f_0(400-1200) scalar meson as the dynamically generated chiral partner of the pion [PDF]

, 2002
The quark-level linear sigma model is revisited, in particular concerning the identification of the f_0(400-1200) (or \sigma(600)) scalar meson as the chiral partner of the pion.

GAUGED HETEROTIC SIGMA-MODELS [PDF]

Modern Physics Letters A, 1994
The gauging of isometries in general sigma-models which include fermionic terms which represent the interaction of strings with background Yang-Mills fields is considered. Gauging is possible only if certain obstructions are absent. The quantum gauge anomaly is discussed, and then the (1, 0) supersymmetric generalization of the gauge action given.

Application of biological variation and six sigma models to evaluate analytical quality of six HbA1c analyzers and design quality control strategy

Artificial Cells, Nanomedicine, and Biotechnology, 2019
Objective To apply biological variation and six Sigma models to evaluate analysis performance of 6 HbA1c analyzers and design the new quality control strategy.Method We collected data of imprecision and inaccuracy from routine internal quality control ...

Supersymmetric Sigma Model Geometry [PDF]

Symmetry, 2012
This is a review of how sigma models formulated in Superspace have become important tools for understanding geometry. Topics included are: The (hyper)kähler reduction; projective superspace; the generalized Legendre construction; generalized Kähler geometry and constructions of hyperkähler metrics on Hermitian symmetric spaces.
