From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Response of granite residual soil slopes under dry–wet cycles

Frontiers in Earth Science
Granite residual soil is widely distributed in the southern coastal areas of China, and the slopes of granite residual soil are prone to instability and failure under the alternating action of rainfall and drying, which will cause great disasters to ...

Enhancing durability of steam‐cured precast concrete culverts using SCMs: A comparative study with delithiated beta spodumene

Structural Concrete, EarlyView.
Abstract Steam curing is commonly used to manufacture precast culverts to accelerate early strength development. This study investigates the effect of supplementary cementitious materials (SCMs) on the permeability properties of steam‐cured precast concrete culverts.

Chemical stabilization of residual granitic soils

Geotecnia, 2004
Este artigo descreve os resultados de um trabalho de investigação realizado para avaliar os efeitos positivos da utilização de cal na estabilização de solos cujo mineral argiloso predominante é a caulinite, como no caso dos solos residuais graníticos. Os efeitos estudados estão relacionados com a alteração da classificação e com o aumento da capacidade

Selective foraging by aardvarks Orycteropus afer on termite mounds: influence of mound structure, spatial distribution, and geology in a savanna landscape

Wildlife Biology, EarlyView.
Predator foraging patterns reflect how animals interact with spatially heterogeneous resources, yet how these patterns manifest across complex landscapes remains poorly understood. We investigated selective excavation of termite mounds by aardvarks Orycteropus afer in Gonarezhou National Park, examining how mound structural characteristics, size ...

Duncan–Chang damage model of granite residual soil under acidic conditions

Frontiers in Earth Science
To study the mechanical properties of granite residual soil under acid leaching conditions, triaxial consolidated undrained shear tests were conducted on granite residual soil collected from Chenggu County, Hanzhong City. In the experiments, environments

Spatiotemporal mapping the usable space of free‐roaming equids across the western United States

Wildlife Society Bulletin, EarlyView.
Identification of the inter‐decadal (2010‐2011) enhancement‐degradation gradients in the usable space for wild equid Herd Management Areas in the Great Basin, USA. Abstract Management of feral equids in the American West is hindered by the lack of a formal habitat map and monitoring system.

Facilitation influences when trees grow, but not growth rate in a dry temperate forest

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Accurately predicting the role of forests in the global carbon cycle requires a detailed understanding of the factors mediating the timing and magnitude of radial stem growth. While weather conditions and topo‐edaphic factors play a critical role in mediating short‐term

ALL POSSIBLE PASTS: Heritage, Simulacra, and Gentrification in Seoul

International Journal of Urban and Regional Research, EarlyView.
Abstract Urban heritage scholars have often criticized simulacra as ‘bad’ copies that degrade the ‘good’ model of the past through commercialization and gentrification. This article challenges such Platonic dichotomies of good/bad and model/copy, arguing that the binary of good heritage and bad simulacra is flawed because heritage is itself actualized ...

Automated particle analysis of D.B. Cooper's tie

Journal of Forensic Sciences, EarlyView.
Abstract Automated particle analysis (APA) using scanning electron microscopy (SEM) and energy‐dispersive x‐ray spectrometry (EDS) is a well‐known method in forensics, especially as it is applied to gunshot residue analysis. Here we describe the analysis of particles lifted from D.B. Cooper's tie, which was left on the hijacked plane in 1971.
