Process‐Induced Anisotropy and Fracture Behavior of Pellet‐3D Printed PLA and PLA/Flax Biocomposites

open access: yesPolymer Composites, EarlyView.
Fused Granular Fabrication of PLA and PLA/flax biocomposites, followed by tensile testing and fracture surface analysis to evaluate the effects of raster orientation and layer number on anisotropy and fracture behavior. ABSTRACT Fused granular fabrication (FGF) enables cost‐effective, large‐scale polymer additive manufacturing; however, the mechanical ...

Perched groundwater simulation using the picard iteration‐based always active cell method

open access: yesRiver, EarlyView.
Abstract Aquitards within the vadose zone impede vertical infiltration, leading to the formation of saturated perched groundwater. Perched groundwater flows laterally along aquitards, resulting in a heterogeneous spatial distribution of groundwater recharge that significantly influences groundwater formation and evolution.

Robust Estimation of Mean and Dispersion Functions in Extended Generalized Additive Models [PDF]

open access: yes
Generalized Linear Models are a widely used method to obtain parametric es- timates for the mean function. They have been further extended to allow the re- lationship between the mean function and the covariates to be more flexible via Generalized ...

Climate Crisis, Human Mobility and Security Challenges in the MENA Region: Implications for Sustainable Development and Regional Stability

open access: yesSustainable Development, EarlyView.
ABSTRACT This study examines the interplay between climate change, violent conflict and forced migration in the Middle East and North Africa (MENA), focusing on asylum flows to the European Union (EU). By integrating high‐resolution climate, conflict and socioeconomic data spanning 2000 to 2023, we develop a comprehensive empirical framework to ...

Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates

open access: yesThe Economic Journal, EarlyView., 2018
The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Twin Transition Priorities Within the Sustainable Development Goals and Economic Freedom in the European Union: A Pillar‐Level Analysis

open access: yesSustainable Development, EarlyView.
ABSTRACT Europe's twin green and digital transition seeks to align sustainability with digitalization, yet it remains unclear whether progress in twin transition‐relevant SDGs coincides with changes in economic freedom dimensions. Using an EU‐27 panel from 2000 to 2024, we examine the link between the Heritage Index of Economic Freedom and a specific ...

Deepening the real options debate: Real options as dynamic optimization

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Is real option theory useful for management research? This topic was hotly debated two decades ago. Real options were said to be inapplicable to management research and to lack conceptual distinctiveness. Whereas responses to the claim about the non‐distinctiveness of real options were disparate, the concern about the theory's

Learning, realizability and games in classical arithmetic [PDF]

open access: yes, 2011
PhDAbstract. In this dissertation we provide mathematical evidence that the concept of learning can be used to give a new and intuitive computational semantics of classical proofs in various fragments of Predicative Arithmetic.
