Quantitative Analysis of Size‐Dependent Structural Disorder in Ruthenium Nanoparticles by Crystal PDF Full‐Space Refinement

Small Methods, EarlyView.
A crystal PDF full‐space refinement approach integrates Bragg diffraction and total scattering to evaluate stacking faults and PDF degradation caused by point defects in ruthenium nanoparticles. This method unveils distinct size‐dependent stacking evolution in fcc‐ and hcp‐based systems, providing a unified and quantitative approach for nanoscale ...

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

Structural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Key features of observational research data preparation for evidence synthesis

Реальная клиническая практика: данные и доказательства
Relevance. Observational studies (OS) play a key role in the healthcare system because they provide real-world data (RWD). Unlike randomized controlled trials (RCTs), such studies better reflect routine medical practice.

Environmental drivers of metapopulation dynamics throughout the full annual cycle in a declining Arctic‐nesting migratory herbivore

Journal of Animal Ecology, EarlyView.
We provide a framework for extending commonly used integrated population models to a metapopulation framework for testing novel ecological hypotheses about how changing environmental conditions within and among subpopulations drive changes in animal abundance.

Mitigating policy uncertainty: What financial markets reveal about firm‐level lobbying

American Journal of Political Science, EarlyView.
Abstract Elections can lead to substantial policy changes and, thus, are a significant source of risk. Firms can respond to such policy uncertainty by lobbying, but it is hard to quantify whether they do so and, if so, how much lobbying benefits them. We construct a new dataset and leverage investors’ expectations of variability in stock returns in the

Historical fishing regimes uncover deep-sea productivity hotspots in the SW Atlantic Ocean

Frontiers in Marine Science
In the deep-sea, abundant and diverse biological communities tend to occur in areas where combinations of geological, physical and biological processes locally enhance trophic-wide productivity, sustaining aggregations of consumers and top predators ...

The slow emergence of the rational investor: Grain markets and grain storage of rural estates in western Germany, eighteenth and early nineteenth centuries

The Economic History Review, EarlyView.
Abstract We develop new datasets of monthly grain prices in 14 urban markets and of the storage and marketing of grain by 5 rural estates located in western Germany between the late seventeenth century and c. 1860. We explore whether observed patterns of monthly prices, sales, and storage of grain are consistent with the rational competitive storage ...

Dynamics of High‐Growth Young Firms and the Role of Venture Capitalists

International Economic Review, EarlyView.
ABSTRACT Motivated by the substantial growth and upfront investments of venture capital (VC)‐backed firms observed in administrative US Census data, this study develops a life‐cycle firm dynamics model. In the model, startups choose the source of financing from VC, angel investors, or banks, depending on their growth potential, and invest in innovation.
