Wavelet invariants for statistically robust multi-reference alignment

Information and Inference: A Journal of the IMA, 2020
AbstractWe propose a nonlinear, wavelet-based signal representation that is translation invariant and robust to both additive noise and random dilations. Motivated by the multi-reference alignment problem and generalizations thereof, we analyze the statistical properties of this representation given a large number of independent corruptions of a target

Measurement invariance of the Hopkins Symptoms Checklist: a novel multigroup alignment analytic approach to a large epidemiological sample across eight conflict-affected districts from a nation-wide survey in Sri Lanka

Conflict and Health, 2017
Background The alignment method, a novel psychometric approach, represents a more flexible procedure for establishing measurement invariance in geographically, ethnically, or linguistically diverse samples, especially in large epidemiological surveys ...

Hydrodynamic theory for nematic shells: the interplay among curvature, flow and alignment [PDF]

, 2016
We derive the hydrodynamic equations for nematic liquid crystals lying on curved substrates. We invoke the Lagrange-Rayleigh variational principle to adapt the Ericksen-Leslie theory to two-dimensional nematics in which a degenerate anchoring of the ...

NLO electroweak corrections in extended Higgs Sectors with RECOLA2 [PDF]

, 2017
We present the computer code RECOLA2 along with the first NLO electroweak corrections to Higgs production in vector-boson fusion and updated results for Higgs strahlung in the Two-Higgs-Doublet Model and Higgs-Singlet extension of the Standard Model.

Accounting for cross-country-cross-time variations in measurement invariance testing. A case of political participation

Survey Research Methods, 2022
"In many works involving measurement invariance testing, researchers concentrate on one type of grouping only, such as countries, even when the comparisons they make involve multiple types of grouping, such as countries and years.

Time-odd components in the mean field of rotating superdeformed nuclei [PDF]

, 1995
Rotation-induced time-odd components in the nuclear mean field are analyzed using the Hartree-Fock cranking approach with effective interactions SIII, SkM*, and SkP.

Measurement Invariance of the Short Home Attachment Scale: A Cross-Cultural Study

Frontiers in Psychology, 2022
The home environment is a particularly significant part of life that is supposed to satisfy inhabitants’ needs, form their identity, and contribute to psychological wellbeing. The construct of home attachment is especially relevant for students as a most

Studying the comparability of student perceptions of teaching quality across 38 countries

International Journal of Educational Research Open, 2023
Student perceptions are rarely used to compare teaching quality across countries due to the challenge of ensuring a comparable construct or achieving exact measurement invariance. The present study aims to evaluate the extent to which student perceptions

Flavor Structure of Soft SUSY Breaking Parameters [PDF]

, 1996
Flavor structure of soft supersymmetry breaking parameters is studied in a certain type of effective supergravity theory derived from moduli/dilaton dominated supersymmetry breaking. Some interesting sum rules for soft scalar masses are presented.
