Veronica paczoskiana is no more than a pine forest ecotype of V. spicata that evolved independently in forest‐steppes of Ukraine and the Altai region

Nordic Journal of Botany, EarlyView.
The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.

Why Active Representation Varies: Cultural Stereotypes and Differential Treatment by Street‐Level Bureaucrats

Public Administration and Development, EarlyView.
ABSTRACT How do cultural stereotypes influence the likelihood that minority street‐level bureaucrats (SLBs) will actively represent marginalized subgroups within their ethnocultural community? While existing scholarship on representative bureaucracy has focused on the conditions under which minority SLBs engage in active representation, this study ...

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

Pest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

The role of identification in data‐driven policy iteration: A system theoretic study

International Journal of Robust and Nonlinear Control, EarlyView.
Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

A Systems Thinking Approach to Mitigating Xenophobia in South Africa for Socio‐Economic Development

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Economic growth in South Africa has led to significant influx of migrants, especially from the African continent, searching for greener pastures. The influx of migrants in South Africa has given rise to competition for scarce resources between locals and migrants.

Influence of steel reinforced grout configuration, and reinforcement ratio on the flexural performance of strengthened continuous RC beams

Structural Concrete, EarlyView.
Abstract The field of reinforced concrete (RC) strengthening continues to evolve as the construction industry seeks cost‐effective and sustainable alternatives to structural replacement. This study, therefore, aimed to comprehensively investigate the pioneering application of steel‐reinforced grout (SRG) for strengthening large‐scale, 3.5‐meter‐long ...

An enhanced analytical model for predicting shear strength in reinforced concrete beams with corroded reinforcement

Structural Concrete, EarlyView.
Abstract This paper presents an analytical model to predict the shear strength of RC beams affected by corrosion within the Level IIb framework of fib Model Code 2020. Corrosion is accounted for by (i) reducing the area of longitudinal reinforcement, (ii) degrading the yield strength of stirrups according to Imperatore's law, and (iii) reducing the ...
