Correlation between topological band character and chemical bonding in a $\mathbf{Bi_{14}Rh_{3}I_{9}}$-based family of insulators [PDF]

Scientific Reports 2016, 6, 20645, 2015
Recently the presence of topologically protected edge-states in Bi$_{14}$Rh$_3$I$_9$ was confirmed by scanning tunnelling microscopy consolidating this compound as a weak 3D topological insulator (TI). Here, we present a density-functional-theory-based study on a family of TIs derived from the Bi$_{14}$Rh$_3$I$_9$ parent structure via substitution of ...

A Rasch Re-Analysis of the Partnership Questionnaire

Sage Open, 2015
The Partnership Questionnaire (PFB) is used favorably in the German language area to measure partnership quality. The goal of the present study is to re-analyze the subscales of the PFB ( Conflict Behavior, Tenderness, Communication) via the Rasch model.

Fixed-node errors in quantum Monte Carlo: interplay of electron density and node nonlinearities [PDF]

, 2013
We elucidate the origin of large differences (two-fold or more) in the fixed-node errors between the first- vs second-row systems for single-configuration trial wave functions in quantum Monte Carlo calculations. This significant difference in the fixed-node biases is studied across a set of atoms, molecules, and also Si, C solid crystals. The analysis

D-Optimal Design for the Rasch Counts Model with Multiple Binary Predictors [PDF]

British Journal of Mathematical and Statistical Psychology Volume 73, 2020, Issue 3, p. 541-555, 2018
In this paper, we derive optimal designs for the Rasch Poisson counts model and the Rasch Poisson-Gamma counts model incorporating several binary predictors for the difficulty parameter. To efficiently estimate the regression coefficients of the predictors, locally D-optimal designs are developed. After an introduction to the Rasch Poisson counts model

Analysis of biology midterm exam items using a comparison of the classical theory test and the Rasch model

JPBI (Jurnal Pendidikan Biologi Indonesia)
In biology learning, test instruments are essential for assessing students' understanding of complex concepts. A test instrument is a crucial factor in learning evaluation; however, its implementation remains minimal.
