White Matter, Cognition, and Electrophysiological Variables in Bipolar Disorder: Using Multimodal Integration of Biomarker Variables Associated With Bipolar Disorder to Elucidate Deficits

Bipolar Disorders, EarlyView.
ABSTRACT Aim This study aimed to evaluate associations in bipolar disorder (BD) across multimodal measures of white matter microstructure (using diffusion tensor imaging; DTI), cognitive, behavioral, and brain electrophysiological measures (using electroencephalography; EEG).

The generalized Hausman test for detecting non‐normality in the latent variable distribution of the two‐parameter IRT model

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract This paper introduces the generalized Hausman test as a novel method for detecting the non‐normality of the latent variable distribution of the unidimensional latent trait model for binary data. The test utilizes the pairwise maximum likelihood estimator for the parameters of the latent trait model, which assumes normality of the latent ...

Modelling non‐linear psychological processes: Reviewing and evaluating non‐parametric approaches and their applicability to intensive longitudinal data

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Psychological concepts are increasingly understood as complex dynamic systems that change over time. To study these complex systems, researchers are increasingly gathering intensive longitudinal data (ILD), revealing non‐linear phenomena such as asymptotic growth, mean‐level switching, and regulatory oscillations.

Measuring Productivity and Convergence Across Countries and Sectors

Bulletin of Economic Research, EarlyView.
ABSTRACT In an effort to understand the evolution of productivity growth across sectors and countries, this paper estimates total factor productivity (TFP) and TFP growth using a semiparametric method applied to 13 OECD countries, leveraging the EU KLEMS data at the industry level over the period 1995–2017.

Neural Geometry Processing via Spherical Neural Surfaces

Computer Graphics Forum, EarlyView.
Abstract Neural surfaces (e.g., neural map encoding, deep implicit, and neural radiance fields) have recently gained popularity because of their generic structure (e.g., multi‐layer perceptron) and easy integration with modern learning‐based setups. Traditionally, we have a rich toolbox of geometry processing algorithms designed for polygonal meshes to

Multiphysics Simulation Methods in Computer Graphics

Computer Graphics Forum, EarlyView.
Abstract Physics simulation is a cornerstone of many computer graphics applications, ranging from video games and virtual reality to visual effects and computational design. The number of techniques for physically‐based modeling and animation has thus skyrocketed over the past few decades, facilitating the simulation of a wide variety of materials and ...

The role of consumer sentiment in the transmission of monetary policy to consumer expenditure

Economica, EarlyView.
Abstract This paper shows that changes in consumer sentiment play a quantitatively important role in the transmission of monetary policy on economic activity. Specifically, the paper's empirical estimates indicate that changes in short‐term consumer sentiment may very well double the negative responses of consumer expenditure to contractionary monetary

Robust Trend Estimation From Temporally Irregular Recreational Fisheries Surveys: A Panel Modeling Framework for Sparse Time Series

Fisheries Management and Ecology, EarlyView.
ABSTRACT Monitoring of recreational fisheries faces ongoing challenges due to irregular data collection and sampling gaps. We used a robust statistical approach combining cross‐sectional panel modeling with generalized linear models to analyze discontinuous time series data.
