Group-level signatures in bonobo sociality

open access: yesEvolutionary Human Sciences
Humans show remarkable differences in social behaviour between families, groups, communities and cultures, whereas such group-level within-species variation in socio-behavioural propensities is typically overlooked in other species.

Group Signature Without Random Oracles from Randomizable Signatures [PDF]

open access: yes, 2020
Group signature is a central tool for privacy-preserving protocols, ensuring authentication, anonymity and accountability. It has been massively used in cryptography, either directly or through variants such as direct anonymous attestations. However, it remains a complex tool, especially if one wants to avoid proving security in the random oracle model.

Unique Group Signatures [PDF]

open access: yes, 2012
We initiate the study of unique group signature such that signatures of the same message by the same user will always have a large common component (i.e., unique identifier). It enables an efficient detection algorithm, revealing the identities of illegal users, which is fundamentally different from previous primitives.

Group actions and higher signatures [PDF]

open access: yesProceedings of the National Academy of Sciences, 1985
Let π be a nontrivial finite group and M be a closed manifold. An interesting question is whether or not M has the R -homology type of a manifold admitting a free π action. Here this problem is studied for actions that are “homologically trivial.” If π 1

A distributed cross-chain mechanism based on notary schemes and group signatures

open access: yesJournal of King Saud University: Computer and Information Sciences, 2023
Blockchain technology has attracted significant attention since its publication. However, most existing blockchain platforms are isolated systems, which makes it difficult to exchange data among different blockchains. The industry has proposed the notary

Correlation of immune infiltration with clinical outcomes in breast cancer patients: The 25‐gene prognostic signatures model

open access: yesCancer Medicine, 2021
Purpose Breast cancer is the most common cancer in women. The aim of this study was to build a prognostic signatures model based on the immune score of the ESTIMATE algorithm to predict survival of breast cancer patients.

Unravelling the instability of mutational signatures extraction via archetypal analysis

open access: yesFrontiers in Genetics, 2023
The high cosine similarity between some single-base substitution mutational signatures and their characteristic flat profiles could suggest the presence of overfitting and mathematical artefacts.
