Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

PLANTS, PEOPLE, PLANET, EarlyView.
As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

Carbon dots in electrochemiluminescence: Mechanisms, interface engineering, and bioanalytical applications

Responsive Materials, EarlyView.
Carbon dots are emerging as versatile electrochemiluminescent nanomaterials whose structure, surface states, and interfacial design jointly determine ECL pathways and performance. This review highlights how mechanistic understanding and materials engineering enable programmable CD‐ECL systems for bioanalysis, imaging, and future intelligent analytical ...

AI‐Powered GPR Characterization of Peatland Underground Cavity Induced by Smoldering Wildfire: A Laboratory Proof‐of‐Concept

Safety Science and Technology, EarlyView.
We present an AI‐assisted ground‐penetrating radar framework to noninvasively detect and quantify smoldering wildfire‐induced subsurface cavities in peatlands. A ResNet model accurately predicts cavity geometry from GPR images, enabling improved assessment of underground fire damage and hazards.

PRECARIZED AGEING‐IN‐PERIFERIA: Low‐Income Older Adults in a Transforming Neighbourhood

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article we investigate how intersecting forms of precarity shape the everyday practices of ageing‐in‐place developed by low‐income older adults in Via Milano, a historically segregated yet rapidly transforming neighbourhood in Brescia, northern Italy. We draw on qualitative and ethnographic research to examine how diverse urban changes—

Integrated Ground-Penetrating Radar and Electrical Resistivity Tomography for Concrete and Masonry Assessment: A Critical Review and Research Agenda

NDT - Journal of Non-Destructive Testing
Ground-penetrating radar (GPR) and electrical resistivity tomography (ERT) provide complementary, but non-unique, observations of concrete and masonry conditions.

Identification of leachate infiltration and its flow pathway in landfill by means of electrical resistivity tomography (ERT)

Environmental Monitoring and Assessment, 2020
Sanitary landfills are a well-planned engineering work for final disposal of municipal solid waste in order to minimize the environmental impacts in soil and groundwater. Therefore, several control systems are installed such as liners and leachate and biogas collectors.

Ground‐penetrating radar amplitudes to roots: A numerical modelling framework for mapping coarse root system architecture

Methods in Ecology and Evolution, EarlyView.
Abstract Observations of three‐dimensional (3D) coarse root system architecture remain limited because most measurement approaches require excavation. Here, we combined dense single‐ and multi‐channel 500 MHz ground‐penetrating radar (GPR) surveys with a flow‐guided connectivity framework to non‐destructively characterise the coarse root architecture ...

Using Electrical Resistivity Tomography (ERT) as a tool in geotechnical investigation of the substrate of a highway

Studia Quaternaria, 2014
Abstract Geological and geotechnical engineering field tests, like structure drillings and dynamic (DPL, DPSH) or static probing (CPT), are considered for a fundamental source of information about soil and water environments. Since Eurocode 7 has been introduced, it has become more common to use also dilatometers (DMT) or pressure meters (PMT ...

Combined Approach to Locate Medieval Fortified Manor Houses in Central Moravia (the Czech Republic)

Archaeometry, EarlyView.
ABSTRACT A systematic prospection of medieval fortified manor houses (FMHs) in Central Moravia (Czech Republic) was conducted with the aim of mapping their distribution and facilitating both further scholarly research and more effective heritage protection by responsible institutions.
