A Numerical Method Combining Cubic Interpolated Propagation and Shifted Grünwald–Letnikov for Fractional Advection–Dispersion Equations

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Recent advances in the numerical solution of fractional partial differential equations have yielded promising results. In particular, the Shifted Grünwald–Letnikov (SGL) approach allows for a generalization of the traditional finite difference method to the context of fractional differential equations.

Analysis of Trajectories of Anxiety Behaviors During Induction of Anesthesia in Children With Multiple Encounters: A Secondary Analysis of a Multicenter Retrospective Cohort Study

open access: yesPediatric Anesthesia, EarlyView.
ABSTRACT Background Preoperative anxiety is a significant stressor for children and is associated with negative postoperative outcomes. Although the incidence of difficult inductions during a single anesthetic encounter is well documented, the longitudinal trajectory of anxiety behaviors in children undergoing repeated anesthesia remains poorly ...

Prediction of Cure‐Induced Wrinkles Aimed at the Manufacturing of Large Wind Turbine Blades

open access: yesPolymer Composites, EarlyView.
The step‐wise progression of the development of cure‐induced wrinkles. Before curing, at room temperature the laminate is resting at the mould face. In the next step, the wrinkle is developing due to thermal gradients. At the end of curing, the composite has cooled down and the undulation is left in, byt the increase in resin stiffness across the ...

Developing a Heterogeneous Attenuation Model for Fiber Reinforced Thermoplastic Composites in the Kilohertz Region of the Ultrasonic Spectrum

open access: yesPolymer Composites, EarlyView.
Acquisition, filtering and modeling by genetic programming (tree pattern) of the acoustic signal for fiber‐filled composites. ABSTRACT This study experimentally investigated the discrete phase contributions of fibers and entrapped air on the attenuation spectrum of a fiber‐filled thermoplastic composite and derives a mathematical expression for sound ...

The Macroeconomic Drivers of Carbon Emissions in East Africa: Capital‐Driven Versus Trade‐Driven Globalization

open access: yesSustainable Development, EarlyView.
ABSTRACT East Africa has recorded strong economic growth over the past three decades alongside a steady rise in carbon emissions, raising concerns about whether the region can sustain growth without worsening environmental pressures. This study incorporates key macroeconomic drivers of carbon emissions using panel data for 9 countries from 1990 to 2023,

Modeling the Thermal Properties of Hydrogen‐Based Direct Reduced Iron Using Computational Thermodynamics and Machine Learning

open access: yessteel research international, EarlyView.
Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.

Promotion in the Australian Public Service: Improvements for Women and Stagnation for Cultural and Linguistic Minorities*

open access: yesEconomic Record, EarlyView.
We investigate whether being female, Indigenous, from a non‐English speaking background (NESB) or having a disability affects career advancement in the Australian Public Service. Over the past 20 years, women have become more likely to get promoted at senior ranks than similar men and just as likely at junior ranks. NESB staff have much lower promotion

Does the All‐Star Award Affect Chinese Analysts' Performance? Evidence From a Regression Discontinuity Design and the Field Le prix All‐Star influence‐t‐il le rendement des analystes chinois ? Données probantes issues d'une régression sur discontinuité et du terrain

open access: yesContemporary Accounting Research, EarlyView.
ABSTRACT This paper examines the effect of the All‐Star award on the performance of Chinese financial analysts. Leveraging unique voting data from 2007 to 2016 and a regression discontinuity design (RDD), we find that the All‐Star award significantly enhances recipients' fundamental analysis. Awarded analysts issue more accurate earnings forecasts, and

Complementarity in alliances: How strategic compatibility and hierarchy promote efficient cooperation in international security

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract How can defense alliances reap the efficiency gains of working together when coordination and opportunism costs are high? Although specializing as part of a collective comes with economic and functional benefits, states must bargain over the distribution of those gains and ensure the costs of collective action are minimized.
