Experimental and simulation studies on damage characteristics, crack development patterns, and strength reduction mechanisms of sandstone under laser irradiation

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
In order to explore the damage characteristics and crack development laws of hard rock under laser irradiation, laser irradiation experiments on sandstone were conducted considering the interaction of three laser parameters: spot diameter, laser power ...

Reclamation Trend of Underground Construction

Procedia Engineering, 2016
Abstract The paper exposes the problems inducing to the active reclamation of underground space in large cities with established historical and architectural development as well as the problems associated its reclamation. Freed up space, as a rule, is transformed into new public spaces, parks and squares; there are new functional communications ...

Principles for Rigorous Design and Application of Synthetic Microbial Communities

Advanced Science, EarlyView.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

Multi‐Dimensional Acoustic Cascaded Holographic Encryption with Instantaneous Visual Decryption via Particle Manipulation

Advanced Science, EarlyView.
Acoustic holograms act as key tools for information encryption, yet current schemes limit encryption dimensionality/security and require time‐consuming decryption. A compact device integrates multi‐dimensional cascaded acoustic holography with particle manipulation, employs extra secret keys, enables rapid decryption, and is validated via 1D/2D/3D ...

Rock splitting with pyrotechnic compositions and secondary propellants [PDF]

MATEC Web of Conferences
In some cases of resources extraction, as well as in construction at industrial and urbanized territories, commercial explosives are not safe enough for the surroundings with regard to the generated fly-rocks, air-blast, toxic fumes, seismic waves and ...

Using and Constraining Nonforward Parton Distributions (Deeply Virtual Neutrino Scattering in Cosmic Rays and Light Dark Matter Searches)

, 2003
We overview the construction of Nonforward Parton Distributions (NPD) in Deeply Virtual Compton Scattering (DVCS). Then we turn to the analysis of similar constructs in the weak sector (electroweak NPD's).

A Perspective on Interactive Theorem Provers in Physics

Advanced Science, EarlyView.
Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

Elastoplastic analysis on deformation and failure characteristics of surrounding rock of soft-coal roadway based on true triaxial loading and unloading tests

Scientific Reports
Since accidents such as roof caving, rock fragmentation, and severe deformation are particularly likely to occur during roadway excavation in soft and thick coal seams, grasping the range and distribution of deformation and fracturing of surrounding rock
