The Anatomical Record, EarlyView.Abstract To solidify their power over society, totalitarian regimes will usually eliminate any dissent, any perceived threats early on. These threats include not only political enemies but also educated and independent segments of society, such as professional associations.

Almost-perfect secret sharing [PDF]
2011 IEEE International Symposium on Information Theory Proceedings, 2011 Splitting a secret s between several participants, we generate (for each value of s) shares for all participants. The goal: authorized groups of participants should be able to reconstruct the secret but forbidden ones get no information about it. In this paper we introduce several notions of non- perfect secret sharing, where some small information ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny
The Anatomical Record, EarlyView.Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

British Educational Research Journal, EarlyView.Abstract This article examines how national education in Hong Kong functions as a contested arena in which state and non‐state actors struggle over the meaning of citizenship, identity and schooling. Using inductive frame analysis of 319 news articles (2020–2025) from five Chinese‐ and English‐language outlets, it identifies diagnostic, prognostic and ...

Comparing Security Notions of Secret Sharing Schemes
Entropy, 2015 Different security notions of secret sharing schemes have been proposed by different information measures. Entropies, such as Shannon entropy and min entropy, are frequently used in the setting security notions for secret sharing schemes.

Learning with Patient Campaigners About a German Drug Scandal
Berichte zur Wissenschaftsgeschichte, EarlyView.The West German drug Duogynon was internationally marketed as a “hormone pregnancy test” (HPT) between the 1950s and 1980s. In the late 1960s it came under suspicion for inducing miscarriage, spina bifida, and a spectrum of birth defects similar to those caused by the sedative thalidomide.

Controlled quantum secret sharing [PDF]
Physica Scripta, 2006 We present a new protocol in which a secret multiqubit quantum state $\ket $ is shared by $n$ players and $m$ controllers, where $\ket $ is the encoding state of a quantum secret sharing scheme. The players may be considered as field agents responsible for carrying out a task, using the secret information encrypted in $\ket $, while the controllers ...
