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

open access: yesDeep 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.

Secret image sharing with reversible steganography

open access: yes, 2012
[[abstract]]The significant essential of secret image sharing approaches is that the revealed content of the secret image must be lossless. Moreover, the distorted stego images can be reverted to the original cover image.

Cheating prevention in secret sharing over GF(pt)

open access: yes, 2001
The work investigates cheating prevention in secret sharing. It is argued that cheating is immune against cheating if the cheaters gain no advantage over honest participants by submitting invalid shares to the combiner.

Rock mechanical properties under reconstructed deep in situ thermo–hydro–mechanical conditions: Implications for CO₂‐related injection scenarios

open access: yesDeep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...

A Unified Approach to Secret Sharing Schemes with Low Distribution Cost

open access: yes, 2012
[[abstract]]In secret sharing schemes, the secret holder has to distribute secret shares to each participant before distributing the secrets. To distribute or redistribute shares is a very costly process with respect to both time and resources.

Sex Differences in Social, Health, and Lifestyle Characteristics Associated With Binge‐Eating Behaviors: Results From a French National Random Population‐Based Study

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective To explore sex differences in social, health and lifestyle characteristics associated with binge‐eating behaviors in a large population‐based study. Method This study included 84,995 participants (women 52.1%) aged ≥ 15 years from the French national random population‐based EpiCov cohort.

Two new color (n, n)-secret sharing schemes

open access: yesTongxin xuebao, 2007
Two methods of(n,n)-secret sharing scheme for color images were presented.Decryption was processed by XOR operation.The reconstruction complexity of the proposed scheme is equivalent to the visual secret sharing scheme,furthermore the quality of the ...
