Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

Polymer Composites, EarlyView.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.

The Search for Disk Perturbing Planets Around the Asymmetrical Debris Disk System HD 111520 Using REBOUND

The Astrophysical Journal
Debris disks, which are optically thin, dusty disks around main-sequence stars, are often found to have structures and/or asymmetries associated with planet–disk interactions.

An Integrated Statistical and Machine Learning Framework for Predicting the Dry Sliding Tribological Behavior of CFRP and GFRP Composites Under Environmental Aging and Loading Conditions

Polymer Composites, EarlyView.
The graphical abstract presents the experimental and data‐driven framework used to investigate the dry sliding tribological behavior of CFRP and GFRP composites. The effects of seawater, engine oil, diesel fuel, aging time, and normal load on the specific wear rate (SWR) and coefficient of friction (COF) were evaluated using pin‐on‐disc tests, ANOVA ...

Viscously Stirring Particle Disks into Lorentzians and Gaussians to Infer Dynamical and Collisional Masses (ARKS XIII)

The Astrophysical Journal
Disks (Keplerian or otherwise, particulate or fluid) are often assumed to have densities that drop off vertically as Gaussians. Recent millimeter-wave imaging of circumstellar debris disks contradicts this assumption, revealing vertical profiles in dust ...

Erosion Resistance Enhancement in Epoxy Composites by Recycled Rubber: Effect of Rubber Type

Polymer Engineering &Science, EarlyView.
Erosion resistance enhancement in epoxy composites by recycled rubber. ABSTRACT Epoxy‐based materials have low erosion resistance due to their brittle nature, and toughness modification stands out for enhancing it. At this stage, the use of waste rubber as a reinforcement component in the composite system is of interest due to its role in providing ...

Exosomal hnRNPA1‐delivered miR‐27a‐3p inhibits the radiation‐induced bystander effect in cervical cancer

Precision Radiation Oncology, EarlyView.
The study showed that TOMO‐mediated RIBE is activated by decreasing exosomal hnRNPA1 protein level and its capability to packaging miR‐27a‐3p. These new findings infer that hnRNPA1 is a novel inhibitor of RIBE, which potentiates to be a new therapeutic target for improving the efficacy of radiotherapy.

Behavioural manipulation of the cabbage stem flea beetle (Psylliodes chrysocephala L): Prospects for push–pull strategies in oilseed rape

Pest Management Science, EarlyView.
Behavioural manipulation of Psylliodes chrysocephala provides promising opportunities for sustainable pest management in oilseed rape systems. This review synthesises evidence on glucosinolates and their volatile isothiocyanate derivatives as phagostimulants and attractants, alongside the repellent or antifeedant effects of non‐host plants, plant ...

Soil‐dependent variation in strigolactone signaling distance revealed by a parasitic seed germination bioassay

Pest Management Science, EarlyView.
A parasitic seed germination bioassay reveals strong soil‐dependent variation in strigolactone signaling distance, controlled by physical and biological soil properties, which shapes signaling range and parasitic weed infection risk. Abstract BACKGROUND Strigolactones are root‐exuded plant metabolites acting as germination stimulants for several ...

The Role of Self-gravity in Debris-disk Warp Formation: The Case of HD 110058

The Astrophysical Journal Letters
We investigate the crucial role of self-gravity in the formation of warps in debris disks, focusing on the HD 110058 system as an example. Using advanced graphical-processing-unit-accelerated N -body simulations, we model the gravitational dynamics of a ...
