The Virial Expansion of the Hydrogen Equation of State in Comparison to PIMC Simulations: The Quasiparticle Concept, IPD, and Ionization Degree

Contributions to Plasma Physics, EarlyView.
ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.

Inference about predictive ability when there are many predictors [PDF]

We enhance the theory of asymptotic inference about predictive ability by considering the case when a set of variables used to construct predictions is sizable.

The Prevention of Eating Disorders in Australian Adolescents: A Modeled Cost‐Effectiveness Study

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Prevention programs for eating disorders (EDs) have the potential to reduce the onset of these diseases and improve the mental health and well‐being of the general population. However, there is mixed evidence on whether routine implementation of such programs at the population level is cost‐effective.

Moment Tests for Window Length Selection in Singular Spectrum Analysis of Short- and Long-Memory Processes [PDF]

In this paper we propose a new methodology for selecting the window length in Singular Spectral Analysis in which the window length is determined from the data prior to the commencement of modeling.

A systematic review evaluating the performance of eDNA methods relative to conventional methods for biodiversity monitoring

Ecography, EarlyView.
The rapid adoption of environmental DNA (eDNA) methods has drastically changed biodiversity monitoring efforts. It is often claimed that eDNA methods are more sensitive and efficient than conventional biodiversity monitoring methods, but it is often unclear what metrics support this claim.

Ultimate 100m World Records Through Extreme-Value Theory [PDF]

We use extreme-value theory to estimate the ultimate world records for the 100m running, for both men and women. For this aim we collected the fastest personal best times set between January 1991 and June 2008.

Alpha, beta and gamma diversity in relatively natural, mixed and transformed landscape scenarios

Ecography, EarlyView.
Biodiversity losses and biotic homogenisation associated with human‐induced land‐cover changes are key issues for ecology. However, the effects of human‐caused land‐use changes on biodiversity change at the landscape scale are not well understood. Combining the PREDICTS global biodiversity database with MODIS satellite‐based land cover from 2001 to ...

Precipitation and tree biomass correlate with the diversity and functional composition of tropical rainforest cricket assemblages across climate and disturbance gradients

Ecography, EarlyView.
Disturbance‐driven changes in rainforest structure and environmental conditions can alter ecosystem functioning, yet the consequences for invertebrate communities – key contributors to decomposition, herbivory, and trophic interactions – are not fully understood, particularly in relation to structural changes in vegetation.

Identification Environment, School Identification and School Burnout: Multilevel Models

European Journal of Social Psychology, EarlyView.
ABSTRACT Most research on well‐being in social psychology has focused on individuals. Based on the social identity approach to health, we examined how the average strength of social identification within a group—a measure of the ‘identification environment’—affects group members’ burnout symptoms and moderates the association between their social ...

Sleep enhances gamma oscillations in the seizure onset zone and broadband activity in the irritative zone of focal cortical dysplasia

Epilepsia Open, EarlyView.
Abstract Objective Focal cortical dysplasia (FCD) is a leading cause of drug‐resistant epilepsy and is associated with sleep‐related seizures, yet the underlying electrophysiological mechanisms during different brain states remain poorly understood. We investigated whether fast oscillations (FOs) within the seizure onset zone (SOZ) and irritative zone (
