Charge generation in organic solar cells: Journey toward 20% power conversion efficiency

Aggregate, Volume 3, Issue 6, December 2022., 2022
Herein, a photophysicist's views on charge generation in organic solar cells is discussed. Recent steady‐state and time‐resolved spectroscopic studies regarding the exciton diffusion to donor:acceptor interfaces, charge transfer at the donor:acceptor interface, and long‐range spatial dissociation of charge transfer states are highlighted.

The relationship between chlorophyllous spores and mycorrhizal associations in ferns: evidence from an evolutionary approach

American Journal of Botany, Volume 109, Issue 12, Page 2068-2081, December 2022., 2022
Abstract Premise Approximately 14% of all fern species have physiologically active chlorophyllous spores that are much more short‐lived than the more common and dormant achlorophyllous spores. Most chlorophyllous‐spored species (70%) are epiphytes and account for almost 37% of all epiphytic ferns.

Could a phase model help to improve translational animal research?

Animal Models and Experimental Medicine, Volume 5, Issue 6, Page 550-556, December 2022., 2022
Transferability of findings from animal research to the human organism is controversially discussed. We propose a phase model which refers to the well‐known process of clinical research in order to improve decision‐making regarding the evidence which is gained in translational animal research.

Genetic population structure of the critically endangered stellate sturgeon (Acipenser stellatus) in the Black Sea basin: Implications for conservation

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1926-1939, December 2022., 2022
Abstract Stellate sturgeon (Acipenser stellatus) is a species of great conservation concern throughout its range. Over the past century, it has experienced a dramatic decline in abundance and distribution in the Black Sea basin. Information regarding the genetic structure of the species is very limited in the region, despite its crucial importance for ...

A Markov chain Monte Carlo method family in incomplete data analysis [PDF]

Ekonomski Anali, 2003
A Markov chain Monte Carlo method family is a collection of techniques for pseudorandom draws out of probability distribution function. In recent years, these techniques have been the subject of intensive interest of many statisticians. Roughly speaking,

A Bayesian homogeneity test for comparing Poisson populations

Applied Stochastic Models in Business and Industry, Volume 38, Issue 6, Page 1158-1171, November/December 2022., 2022
Abstract For a wide class of daily applications in industrial quality control, there may be interest in comparing several Poisson means. A large catalogue of frequentist procedures for this hypothesis testing problem is available. However, some common drawbacks of them are their low power, interpretation of the p$$ p $$‐values for multiple comparison ...

Bayesian Parameterization of Continuum Battery Models from Featurized Electrochemical Measurements Considering Noise**

Batteries &Supercaps, Volume 6, Issue 1, January 2023., 2023
We introduce a computer algorithm that incorporates the experience of battery researchers to extract information from experimental data reproducibly. This enables the fitting of complex models that take up to a few minutes to simulate. For validation, we process full‐cell GITT measurements to characterize the diffusivities of both electrodes non ...

Goodness‐of‐fit tests in proportional hazards models with random effects

Biometrical Journal, Volume 65, Issue 1, January 2023., 2023
Abstract This paper deals with testing the functional form of the covariate effects in a Cox proportional hazards model with random effects. We assume that the responses are clustered and incomplete due to right censoring. The estimation of the model under the null (parametric covariate effect) and the alternative (nonparametric effect) is performed ...

Bayesian time‐varying autoregressive models of COVID‐19 epidemics

Biometrical Journal, Volume 65, Issue 1, January 2023., 2023
Abstract The COVID‐19 pandemic has highlighted the importance of reliable statistical models which, based on the available data, can provide accurate forecasts and impact analysis of alternative policy measures. Here we propose Bayesian time‐dependent Poisson autoregressive models that include time‐varying coefficients to estimate the effect of policy ...
