Is There a Brazilian J-Curve? [PDF]

open access: yes
We show that Marshall-Lerner condition holds for Brazilian trade balance, and discard a J-curve in the short run. We present these results using impulse-response functions in a variety of (linear and nonlinear) models, including Markov-switching, vector ...

Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

open access: yesAdvanced Engineering Materials, EarlyView.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Enhancement of the Through‐Thickness Electrical Conductivity of Carbon‐Fiber‐Reinforced Plastics Using Large Graphite Particles

open access: yesAdvanced Engineering Materials, EarlyView.
To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.

External validation and comparative performance of ACLS, SARICA, NULL-PLEASE, BDR scores for in-hospital mortality after out-of-hospital cardiac arrest: a multicenter retrospective cohort study

open access: yesResuscitation Plus
Background: Prognostic scores are used to estimate outcomes after out-of-hospital cardiac arrest (OHCA), but their comparative performance in external cohorts remains unclear.

3D‐Printed Titanium Gyroid Scaffold Structure Integrated With Tough Hybrid Materials for Cartilage Replacement

open access: yesAdvanced Engineering Materials, EarlyView.
This study proposes a potential device design for joint cartilage replacement. Silica‐polytetrahydrofuran (SiO2‐PolyTHF) hybrids with customizable mechanical properties were developed to mimic the characteristics of a natural meniscus. These were synthesized through a two‐pot sol–gel hybrid process.

An Equipotential Disk Model with Irradiation for Nova-like Variables

open access: yesThe Astrophysical Journal
The reflection effect is here incorporated within an earlier analytic binary system light- and velocity-curve model that includes a circumstellar equipotential disk.

Dynamics of the trade balance: The Turkish J-curve [PDF]

open access: yes
The J-curve hypothesis suggests a specific pattern for the response of trade balance to real exchange rate changes: a real depreciation initially worsens the trade balance, but through time the trade balance improves, and thus the response of the trade ...

Rotary 3D Printing With Integrated Electroplating

open access: yesAdvanced Engineering Materials, EarlyView.
A rotary material extrusion platform integrates localized copper electroplating with printing and encapsulation to fabricate cylindrical polymer–metal structures containing fully embedded, low‐resistance conductive pathways that enable internal Joule heating and thermally activated shape‐memory responses.

Mitigating Creep Anisotropy and Enhancing Performance in Additively Manufactured Ni‐Based Superalloys: A Review

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing introduces pronounced microstructural and crystallographic anisotropy in Ni‐based superalloys, resulting in orientation‐dependent creep deformation and damage. This review identifies the key microstructural origins of creep anisotropy, examines their influence on dominant deformation mechanisms, and highlights processing ...

Electrodeposition in Structural Lattices of Variable Architectures

open access: yesAdvanced Engineering Materials, EarlyView.
Electrodeposition enables geometry‐sensitive, autonomous void filling while simultaneously tuning chemical and mechanical properties. The development of approaches that can autonomously fill and heal material voids and yield composites with tailorable properties is increasingly relevant in engineering.
