Origin of the Asymmetric Gas Distribution near the Co-orbital Lagrange Points of an Embedded Planet

The Astrophysical Journal
Hydrodynamic simulations of planet–disk interactions often show material accumulation near the co-orbital Lagrange points L _4 and L _5 —features that may correspond to observed crescents in protoplanetary disks. Intriguingly, these simulations also show

Property Rights Entrepreneurship: The Drive for Product, Asset, and Resource Excludability

Managerial and Decision Economics, EarlyView.
ABSTRACT Property rights are foundational to market economies, and entrepreneurial activity depends heavily on the excludability afforded by property rights. Yet, the role of entrepreneurs in shaping the evolution of property rights has been so thoroughly taken for granted that it often vanishes from analyses.

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

An Open Database of Lunar Regolith and Simulants Properties

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Lunar regolith, the layer of unconsolidated material covering the Moon's surface, is central to the science and technology developed for the Moon, notably related to in‐situ science investigations, resource utilization, surface infrastructure, and mobility systems.

Disk2Planet: A Robust and Automated Machine Learning Tool for Parameter Inference in Disk–Planet Systems

The Astrophysical Journal
We introduce Disk2Planet, a machine-learning-based tool to infer key parameters in disk–planet systems from observed protoplanetary disk structures. Disk2Planet takes as input the disk structures in the form of 2D density and velocity maps, and outputs ...

The place bonding potential of nature‐based citizen science with refugee children and youth

People and Nature, EarlyView.
Abstract Nature‐based citizen science often involves close interaction with places. In addition to providing benefits, such as learning opportunities and contact with nature, it can facilitate and shape bonds between people and places. Research exploring the place bonding potential of such projects is still in its infancy. This paper addresses this gap

Circumplanetary Disk Candidate in the Disk of HD 163296 Traced by Localized Emission from Simple Organics

The Astrophysical Journal Letters
Atacama Large Millimeter/submillimeter Array observations suggest that the disk of HD 163296 is being actively shaped by embedded yet unseen protoplanets, as indicated by numerous gas and dust substructures consistent with planet–disk interaction models.

2‐Amino‐3H‐phenoxazin‐3‐one is a lead inhibitor of Cuscuta campestris early development: structure–activity relationships of o‐aminophenol‐derived allelochemicals

Pest Management Science, EarlyView.
Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

The role of inner disk edges in shaping ultra-short-period planet systems around late M dwarfs

Astronomy & Astrophysics
Context. Close-in rocky planets are the most common type of exoplanets around late M dwarfs, ranging from more temperate worlds to highly irradiated lava planets with molten surfaces, and many theoretical studies have attempted to explain their formation.

Biocontrol and plant growth‐promoting potential of Streptomyces strains against fungal pathogens of tomato and wheat for a sustainable agriculture

Pest Management Science, EarlyView.
This study highlights the biocontrol potential of Streptomyces strain Strep_22. In vitro, it inhibits key fungal pathogens by 91.52%. In vivo, it significantly reduces disease incidence in wheat and tomato while enhancing biomass, shoot, and root development, offering a highly promising, sustainable ecological alternative to chemical pesticides ...
