Photothermal bubble: Dynamics, manipulation, and applications

Droplet, EarlyView.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.

Temporal Energy: An Extension of Classical Gravity and Nuclear Interaction Theory

Abstract This paper proposes a unified model of fundamental interactions based on the redistribution of temporal energy — a physical property associated with matter’s progression through time. The model interprets gravity and nuclear forces as manifestations of temporal gradients, offering an alternative to classical descriptions in General Relativity

Upper bound limit analysis of coral reef limestone cavern roof stability incorporating a tension‐shear failure mechanism with tensile‐strength cut‐off

Deep Underground Science and Engineering, EarlyView.
For the roof of coral reef limestone caverns, a novel tension‐shear composite failure mechanism was developed. The most critical tensile crack model was identified using a hybrid optimization algorithm, and the stability of the cavern roof was analyzed accordingly.

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

Deep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Modeling proppant transport and settling in a 3D propagating fracture

Deep Underground Science and Engineering, EarlyView.
A versatile multiphysics tool is presented for simulating the complex processes involved in hydraulic fracturing treatments. The model couples fracture opening and propagation, variable‐density slurry flow, and proppant particle transport within the multiphysics object‐oriented simulation environment framework, based on two‐phase mixture equations and ...

Prospects in classical and quantum gravity : from theory to phenomenology

, 2019
General Relativity (GR) is a highly successful theory whose predictions are still being confirmed a hundred years later. However, despite its significant success, there still remain questions beyond the realm of its validity. The reconciliation of Standard Model (SM) and GR or Quantum Mechanics (QM) and GR point towards the need for a potential ...
