Aperiodic logarithmic signatures

Journal of Mathematical Cryptology, 2012
In this paper we propose a method to construct logarithmic signatures which are not amalgamated transversal and further do not even have a periodic block.

Efficient Revocation in Group Signatures [PDF]

, 2001
We consider the problem of revocation of identity in group signatures. Group signatures are a very useful primitive in cryptography, allowing a member of a group to sign messages anonymously on behalf of the group. Such signatures must be anonymous and unlinkable, but a group authority must be able to open them in case of dispute.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Distinct Expansion of Group II Introns During Evolution of Prokaryotes and Possible Factors Involved in Its Regulation

Frontiers in Microbiology, 2022
Group II introns (G2Is) are ribozymes that have retroelement characteristics in prokaryotes. Although G2Is are suggested to have been an important evolutionary factor in the prokaryote-to-eukaryote transition, comprehensive analyses of these introns ...

Group actions and higher signatures [PDF]

Proceedings 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

Cup‐Like Nuclei Is a Hallmark of DUX4/ERG Acute Lymphoblastic Leukemia and Reveals Cytoplasmic Mitochondria Accumulation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Cup‐like nuclei are a distinctive morphological feature observed in certain cases of acute lymphoblastic leukemia (ALL). We provide evidence that they characterize DUX4/ERG ALL independently of IKZF1 deletion and reveal marked mitochondrial accumulation in this ALL subset.

Central Nervous System Neuroblastoma, FOXR2‐Activated: A Pooled Analysis of Published Clinical Outcomes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) neuroblastoma, FOXR2‐activated, is a recently recognized entity in the WHO CNS5 classification, defined by activation of the FOXR2 transcription factor and unique histopathological features. This review synthesizes available literature and pooled clinical data, providing insight into demographics ...

Unconditionally Secure Group Signatures

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2009
A group signature scheme introduced by Chaum and Van Heyst allows a group member to sign messages anonymously on behalf of the group. However, in the case of a dispute, the identity of a signer of a group signature can be revealed only by a privileged entity, called a group manager.
