Survey Research Methods, 2020 Different factors are known to affect the comparability of multinational, multicultural and multiregional (‘3MC’) survey data. These include factors relevant to the design of the questionnaire in different contexts (such as cultural differences in how a

Frontiers in Psychology, 2021 Studies investigating differences in mental health problems between self-employed and employed workers have provided contradictory results. Many of the studies utilized scales validated for employed workers, without collecting validity evidence for ...

Invariant measures of the pair: state, approximate filtering process [PDF]
Colloquium Mathematicum, 1991 The paper contains a proof and discussion of a theorem related to a problem in discrete time filtering which may be summarized as follows. The state is a Markov process with an initial law \(\nu\). The filter is then also Markov. It is known that, if the state has a unique invariant measure, then, under certain conditions, the filter has in turn a ...

INVARIANT MEASURES OF STOCHASTIC PERTURBATIONS OF DYNAMICAL SYSTEMS USING FOURIER APPROXIMATIONS [PDF]
International Journal of Bifurcation and Chaos, 2011 We consider dynamical system τ : [0, 1] → [0, 1] and its stochastic perturbations [Formula: see text], N ≥ 1. Using Fourier approximation, we construct a finite dimensional approximation P N to a perturbed Perron–Frobenius operator.

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

High Order Numerical Approximation of the Invariant Measure of Ergodic SDEs
SIAM Journal on Numerical Analysis, 2014 We introduce new sufficient conditions for a numerical method to approximate with high order of accuracy the invariant measure of an ergodic system of stochastic differential equations, independently of the weak order of accuracy of the method. We then present a systematic procedure based on the framework of modified differential equations for the ...

FEBS Letters, EarlyView.Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

An Investigation of Bayesian Approximate Measurement Invariance with Longitudinal Data
, 2023 The Bayesian structural equation modeling approach was introduced by Muthén and Asparouhov (2013) to test measurement invariance (MI) across multiple groups or multiple time points.

An Approximation of the Invariant Measure for the Stochastic Navier-Stokes [PDF]
, 2009 Kolmogorov’s statistical theory of turbulence is based on the existence of the invariant measure of the Navier-Stokes flow. Recently the existence of the invariant measure was established in the three-dimensional case [2]. It was established for uni-directional flow in [1] and for rivers in [3].

Molecular Oncology, EarlyView.Enterotoxigenic Bacteroides fragilis is a gut bacterium linked to bowel cancer. We propose that its toxin acts along two routes: at the cell surface, cutting the adhesion protein E‐cadherin and triggering inflammation; and inside the cell, delivered by bacterial vesicles, switching on NOD1 and cancer stem cell programs.
