External Vibrations on Early‐Age Concrete: A Review

Engineering Reports, Volume 8, Issue 5, May 2026.
Scientific illustration of external vibration, their influencing properties and effects, possible outcomes and measures adapted. ABSTRACT Early‐age concrete exhibits limited mechanical strength, making it highly susceptible to external disturbances such as vibrations from construction activities, traffic, or nearby machinery which can disrupt internal ...

A Study of Improved Inversion Algorithms for Surface–Borehole Transient Electromagnetic Data Based on BFGS Method

Minerals
The surface–borehole transient electromagnetic method (TEM) employs surface-based transmission and downhole reception to collect electromagnetic data. This configuration offers distinct advantages over traditional TEM approaches by effectively attenuating surface electromagnetic noise and cultural interference, leading to enhanced signal strength and ...

Deciphering transitions within ice–debris complexes in the Northern Tien Shan through surface characteristics and internal structure

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Geophysical (GPR and ERT) data reveal a transition from buried glacial ice to an ice–debris mixture within ice–debris complexes in Kazakhstan; this transition is reflected in surface morphological and kinematic characteristics. We identify some relationships between internal ice content and associated surface kinematics but caution against ...

A Comparison of Surface-to-Coal Mine Roadway TEM and Surface TEM Responses to Water-Enriched Bodies

IEEE Access, 2019
The surface transient electromagnetic method (TEM) is a geophysical technology normally used in detecting water-enriched zones. However, with an increase of mining depth, the accuracy and reliability of surface detection is gradually reduced, and surface

Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone

Journal of Field Robotics, Volume 43, Issue 3, Page 1646-1660, May 2026.
ABSTRACT This paper describes the design, development, and real‐world testing of an autonomous drone for subterranean exploration, known as “Prometheus.” Driven by requirements from industry that the drone be able to be deployed through areas of restricted access, Prometheus was designed to be directly deployed through a 150 mm aperture.

A Decade of Airborne Electromagnetic Surveying Lake Menindee (Australia) Under Varying Water Levels

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Time domain airborne electromagnetic (AEM) surveying is a mature geophysical tool for imaging the Earth's shallow subsurface. It produces images of the electromagnetic conductivity structure of the earth, down to depths of a few hundred metres.

Magma and Volatile Pathways Beneath Sakurajima Volcano From Self‐Potential, Helium Isotopes, and Broadband Magnetotellurics

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract At frequently erupting volcanoes, magma and volatiles ascend through established pathways, but the complete picture of their branching and supply system remains unclear. We integrated self‐potential (SP), broadband magnetotelluric (MT), and helium isotope observations to image magma and volatile pathways beneath Sakurajima Volcano.

A Hydrogeophysical Survey Utilising the sTEM and sTEMprofiler Systems: Transient Electromagnetic Data and Resistivity Models

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
We present a transient electromagnetic dataset from northwestern Denmark acquired with the novel sTEMprofiler system, mapping buried Quaternary valleys. The open dataset, including raw data and resistivity models, enables benchmarking of inversion methods and integration into geological and hydrological studies. ABSTRACT Transient electromagnetic (TEM)

Grouting Treatment of Water and Mud Inrush in Fully Weathered Granite Tunnel: A Case Study

Geofluids, 2020
When mountain tunnel passes through completely weathered granite strata, water and mud inrush is easy to occur, causing casualties and economic losses. Grouting is a common and effective treatment method for water and mud inrush disaster.
