Tracking Post‐Consumer Packaging Plastics With Global Positioning Systems: Pilot Study in Malaysia

Sustainable Development, EarlyView.
ABSTRACT Landfilling and the mismanagement of packaging plastic waste pose significant challenges in developing countries, especially in Southeast Asia. There is an empirical gap in plastic waste management data, which is largely handled by informal players despite established municipal solid waste collection systems.

The Radial Distribution of Gaia-selected Blue-straggler Candidates in the Old Open Cluster NGC 2158

The Astronomical Journal
We measure the projected radial distribution of blue-straggler-star (BSS) candidates in NGC 2158 using a Gaia DR3 membership catalog. The numerator and RGB/red-clump (RGB/RC) denominator are selected with the same thresholds, P _mem ≥ 0.8 and RUWE

Hierarchically Rough rGO/HAp Nanocoatings on SLM Ti–6Al–4 V Implants for Enhanced Biointegration

Small, EarlyView.
This study investigates HAp/rGO bioactive coatings on Ti‐6Al‐4V fixation implants fabricated by selective laser melting with systematically varied volumetric energy density to tailor the as‐built surface state. Composite coatings were deposited by electrophoretic deposition and characterized using micro‐CT, profilometry, FESEM/EDS, and detailed XPS to ...

Binary Fraction in Galactic Star Clusters: FSR 866, NGC 1960, and STOCK 2

The Astronomical Journal
The study of binary stars in different astronomical environments offers insights into the dynamical state of the hosting stellar systems. The binary fraction in fact plays a crucial role in the dynamical evolution of stellar systems, regulating processes

BD+43° 3654 – a blue straggler?

, 2008
The astrometric data on the runaway star BD+43° 3654 are consistent with the origin of this O4If star in the center of the Cyg OB2 association, while BD+43° 3654 is younger than the association. To reconcile this discrepancy, we suggest that BD+43° 3654

Anisotropy Thermal Properties of Electrically Insulating Thin Films and Sheets: A Review

Small Methods, EarlyView.
Thermally conducting and electrically insulating materials with anisotropy properties play an integral role in advanced thermal management, in particular for electronic devices. This review discusses recent progress in enhancing thermal conductivity and controlling the thermal anisotropy between in‐plane and cross‐plane (through‐thickness) directions ...

Kinematic fingerprints of dynamical ejection: High-velocity blue straggler stars in the halo of NGC 188

Astronomy & Astrophysics
Context. Open clusters are fundamental laboratories for studying stellar dynamics. In dynamically mature systems such as NGC 188 (~7 Gyr), mass segregation is expected to concentrate massive objects in the core, making the presence of high-mass stars in ...

Identification of invisible damage in prestressed concrete bridges—A demonstrator case using coda wave interferometry

Structural Concrete, EarlyView.
Abstract During their life cycle, prestressed concrete bridges are prone to wire breaks of their tendons due to fatigue or stress corrosion cracking. However, not all structures show visible cracking on the surface, which would provide timely warning of otherwise invisible damage. Brittle failure may occur.

Once a Triple, Not Always a Triple: The Evolution of Hierarchical Triples That Yield Merged Inner Binaries

The Astrophysical Journal
More than half of all main-sequence (MS) stars have one or more companions, and many of those with initial masses 10 yr) companions. Furthermore, both BSS binaries and DWDs exhibit signatures of WD birth kicks.

Reconciling Goffman and Disability Studies: “Interactional” and “Structural” Stigma in the Lives of Parents of Learning‐Disabled Adults

Symbolic Interaction, EarlyView.
Erving Goffman cuts a divisive figure in disability studies. Some criticize his conception of “stigma” as deviance‐focused and as ignoring structural forces that shape personal encounters. Others praise his recognition of stigma as an interactional phenomenon.
