Investigation on hard‐rock breaking performance and auxiliary mechanism of picks assisted with both‐sided high‐pressure water jets

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 2, Page 581-596, June 2026.
This paper investigates the high‐pressure water jet‐pick combined rock‐breaking mode (HPC), which employs high‐pressure water jets to precut grooves on both sides of the picks. The rock‐breaking patterns and performance of the HPC method are obtained, and the auxiliary rock‐breaking mechanism of water jet grooving is revealed.

Using LiDAR to quantify, map, and conserve late‐successional and old‐growth forest in Maine, USA

open access: yesEcosphere, Volume 17, Issue 6, June 2026.
Abstract The world continues to lose late‐successional and old‐growth (LSOG) forest as the human population and demand for wood fiber grow. However, older forest age classes provide structural and compositional characteristics important to biodiversity that are often not present in forests managed for timber.

Evaluation of Modeling Assumptions for Predicting Structural Damage and Train Derailment Under Earthquake Loading

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 7, Page 1514-1532, June 2026.
ABSTRACT The rapid development of new railway networks and the aging of existing infrastructure in seismic‐prone regions continue to motivate the need for efficient methods to simulate the dynamic behavior of coupled train track structure systems. While detailed train–structure interaction (TSI) models can capture complex mechanisms, they are often too

Study on the Influence of Slope Static Load on Shallow Lining Support Structure

open access: yesEnergy Science &Engineering, Volume 14, Issue 6, Page 2721-2735, June 2026.
On the basis of the background of the shallow‐buried main adit supported by stone lining, the mechanical model of the supporting structure is constructed, and the stability of the supporting structure is analyzed by using the methods of field investigation, theoretical analysis, and numerical simulation.

The influence of ex‐tropical cyclones on marine terrace retreat

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
Ex‐tropical cyclones can damage the integrity of marine terrace structures and contribute to erosion, but they are sometimes too infrequent to explain the longer term erosion rates of coastlines. Abstract High magnitude events, like Ex‐Tropical Cyclones, are likely to change in their trajectory, magnitude, and frequency under future climate change ...
