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.

Deep Underground Science and Engineering, EarlyView.This study presents an integrated workflow to evaluate secure and large‐scale CO2 storage in depleted oil reservoirs of the Cambay Basin, India. Industrial CO2 sources are systematically matched with mature oil fields using a quantitative source–sink framework to minimize transport distance and cost.

LWE‐based verifiable essential secret image sharing scheme ((t,s,k,n)$( {t,s,k,n} )$ ‐ VESIS)
IET Image ProcessingIn traditional secret image sharing schemes, shareholders have similar situations, and to recover the secret image, they must be present as many as the threshold.

Geometric Shared Secret and/or Shared Control Schemes [PDF]
, 1991 A shared secret scheme is normally specified in terms of a desired security, Pd, and a concurrence scheme, Γ. The concurrence scheme (aka access structure) identifies subsets of participants (also called trustees or shareholders) each of which should be able to cooperatively recover the secret and/or initiate the controlled action.

World's fastest 10 000‐m breakthrough: The XY‐22 well redefines deep‐earth access in the Tarim Basin
Deep Underground Science and Engineering, EarlyView.The Tarim Basin in northwestern China hosts one of the world's deepest petroleum systems, exemplified by the XY‐22 ultra‐deep well (bottom depth: 11 116 m; ~220°C, ~145 MPa). This study integrates tectonic mapping, geological cross‐sections, ultraviolet fluorescence microscopy, and optical photothermal infrared (OPTIR) spectroscopy to characterize ...

Deep Underground Science and Engineering, EarlyView.This paper conducts a numerical simulation study on the construction of a deep‐buried tunnel in an anisotropic stratum area. A statistical analysis of the effects of two anti‐faulting design measures, namely, a conventional design and an articulated design, is carried out, and the results demonstrate the effectiveness of the anti‐faulting structures ...

Secret sharing in a special linear group
InformatikaObjectives. The problem of developing the mathematical foundations of modular secret sharing in a special linear group over the ring of integers is being solved.The relevance of the problem is reduced to the fact that a large number of requirements are ...

Environmental Policy and Governance, EarlyView.ABSTRACT Freshwater availability is a critical climate change challenge in coastal delta regions. This challenge requires a transformative change toward circular water management. While experimentation and collaborative governance are recognized as enablers of transformative change, their interaction remains complex and insufficiently understood ...

Environmental Policy and Governance, EarlyView.ABSTRACT Water governance is increasingly influenced by a paradox at the nexus of environmental scarcity and food security. Escalating water scarcity crises coincide with geopolitical disruptions that have exposed the fragility of global food supply chains, prompting states to expand domestic food production at the expense of water conservation ...
