Experimental and Numerical Assessment of Progressive Damage in CF/PEEK Laminates Under Monotonic and Progressive Cyclic Four‐Point Bending

Polymer Composites, EarlyView.
Experimental four‐point bending of CF/PEEK laminates under monotonic and progressive cyclic loading is assessed using classical lamination theory and a calibrated Hashin progressive damage model. ABSTRACT Carbon‐fiber‐reinforced PEEK composites combine high specific strength, corrosion resistance, and damage tolerance, supporting their use in aerospace,

Performance improvement of carbon fiber‐reinforced ABS composites by introducing fullerene nanoparticles

Polymer International, EarlyView.
Fullerene particles were incorporated with CF‐reinforced acrylonitrile–butadiene–styrene terpolymer (ABS) matrix at three different compositions by a melt‐compounding process. These insights are crucial for the optimization of conductive hybrid composites for various applications.

Synergistic recovery of Pr, Eu, and Ce from gold mine tailings using bioleaching and oxalic acid pretreatment

Scientific Reports
Mining activities produce a significant amount of gold mine tailings (GMT) rich in rare earth elements. Despite this, little information is available regarding the effective extraction of these precious elements from GMT. We describe a novel strategy for

Path‐Based Deep Reinforcement Learning for On‐Board Routing in Satellite Constellation Networks

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Efficient usage of available network resources is a crucial factor for broadband services in interconnected satellite constellations. To meet required quality of service standards under heavy network loads, it is essential to optimize traffic distribution among the intersatellite links. To address this challenge, we propose an adaptive traffic

Low‐Complexity Hybrid Beamforming for LEO Satellites: Beam Update Rate Analysis and Advanced Adaptive Precoding

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Low Earth Orbit (LEO) satellite constellations offer unprecedented opportunities for global broadband connectivity but pose significant beamforming challenges due to rapid platform motion and stringent onboard hardware constraints. Fully digital architectures, while optimal in theory, remain impractical for satellite payloads, motivating ...

Opportunities for Australia Amid China's Carbon‐Neutral Transition: Input–Output Approach With Analysis of Australian Renewable Potential

Sustainable Development, EarlyView.
ABSTRACT A major transformation in China's energy mix is underway as the country pursues carbon neutrality by 2060, posing significant structural challenges for Australia as a major exporter of carbon‐intensive resources. This study examines the economic impacts of China's decarbonisation on Australia by applying static and dynamic input–output (IO ...

A Cytoplasmic pH Sensor Redefines Gating in Bacterial Urea Channels and Acid Resistance

Small, EarlyView.
Bacterial survival in acidic environments requires pH‐gated urea channels. Utilizing complementary approaches, we identify a conserved cytoplasmic glutamic acid residue as a pH sensor in UreI channels. Whereas Gram‐positive bacteria rely solely on this sensor, Gram‐negative bacteria employ a dual‐sensor mechanism with periplasmic residues, revealing a ...

The Impact of “Mother‐Friendly Care” Accreditations on Patient Choice: Evidence From Brazil

Southern Economic Journal, EarlyView.
ABSTRACT We examine the impact of Brazil's “Mother‐Friendly Care” accreditation program on hospital choice. Using administrative data on births in the Brazilian public health system from 2008–2019, we estimate a nested logit demand model that allows for differential substitution patterns based on existing Baby‐Friendly Hospital Initiative (IHAC ...
