Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Mechanism Design and Kinematics Analysis of a 6-DOF Manipulator

Jixie chuandong
Aiming at the problems of large inertia, low flexibility and difficulty in working in narrow space of traditional manipulators, a new type of wire-driven manipulator with 6-DOF is designed, and its forward and inverse kinematics are studied.

Modeling and monitoring injectivity evolution during cold CO2 injection with field evidence from aquistore carbon capture and storage operations

Deep Underground Science and Engineering, EarlyView.
This work integrates 5 years of field data from the Aquistore CCS project with a non‐isothermal THM modeling framework to explain how cold CO2 injection alters injectivity over time. The study shows that sustained cooling near the wellbore reduces effective stresses, promotes tensile micro‑cracking, and leads to semi‑reversible permeability enhancement

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Charting Water‐in‐Natural‐Salt (WiNS) Electrolytes. Part I: Effect of Anion's Alkyl Tail Length

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
At 20 m, potassium carboxylates from formate to butyrate reveal anion tail‐controlled nanostructure. SAXS shows a pre‐peak shifting to lower q with chain length. Molecular dynamics reproduces S(q) and attributes it to concentration fluctuations forming bicontinuous segregation.

Surface Consistent Seismic Hazard Assessment in the Shillong Plateau, Northeast India: A Probabilistic Approach Using Multiple Source Models and a Logic Tree Framework

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT We perform probabilistic seismic hazard analysis (PSHA) in the Shillong Plateau by clubbing the up‐to‐date earthquake data and seismotectonic properties of the study area. Twenty‐one areal seismic sources are delineated based on the updated earthquake catalog, tectonic, and fault plane solutions.
