An Improved Group Signature Scheme with VLR over Lattices

For group signatures (GS) supporting membership revocation, verifier-local revocation (VLR) mechanism is the most flexible choice. As a post-quantum secure cryptographic counterpart of classical schemes, the first dynamic GS-VLR scheme over lattices was put forward by Langlois et al. at PKC 2014; furthermore, a corrected version was shown at TCS 2018. However, both designs are within Bonsai trees and featuring bit-sizes of group public-key and member secret signing key proportional to log N where N is the group size; therefore, both schemes are not suitable for a large group. In this paper, we provide an improved dynamic GS-VLR over lattices, which is efficient by eliminating a O log N factor for both sizes. To realize the goal, we adopt a more efficient and compact identity-encoding technique. At the heart of our new construction is a new Stern-type statistical zero-knowledge argument of knowledge protocol which may be of some independent cryptographic interest.

Corrigendum: The affine part of the Picard scheme

We give a corrected version of Theorem 3, Lemma 4, and Proposition 9 in the above-mentioned paper, which are incorrect as stated (as was pointed out by O. Gabber).

Analytical description of nanowires. I. Regular cross sections for zincblende and diamond structures. Corrigendum

In the paper by König & Smith [Acta Cryst. (2019), B75, 788–802], several equations had minor errors in their coefficients defining characteristic lengths and area of zinc-blende nanowire cross sections, thereby deviating from the exact analytical solution by 1.4 ± 0.8 %. A fully corrected version of the paper is provided.

Assessment of the activity and organ damage in antiphospholipid syndrome

The review provides a brief description of the clinical and serological markers of antiphospholipid syndrome (APS), risk factors for the development and recurrence of thrombosis in APS. A complete description of the GAPSS and its simplified (corrected) version, adjusted GAPSS (aGAPSS), as well as the DIAPS, is presented. These scales allow one to determine the activity of APS and reflect the range of cumulative and/or irreversible damage due to the disease.

Correction: In-vitro antidiabetic activities, chemical compositions, antioxidant activities, and toxicity of black tea polysaccharides as a potential source of dietary ingredients

There is an error in Table 2 in the published article, Journal of Food Bioactives, 2021;13:93–101, doi: 10.31665/JFB.2021.13263. The correct value in column “mg/100 g” under “D-glucose” is “59.50 ± 7.80”, not “9.50 ± 7.80”. The authors have included a corrected version of the table below.

Correction: Bustamante et al. Determining When an Algebra Is an Evolution Algebra. Mathematics 2020, 8, 1349

The authors wish to make the following corrections to this paper [1] (see corrected version in postprint [2]):On page 2, paragraph 4, complete the first sentence ‘In Theorem 2 we show that if A is a real algebra and B is a basis of A then B also is a basis of Aℂ, the complexification of A (with the same multiplication structure matrices) and that A is an evolution algebra if, and only if, Aℂ is an evolution algebra’ with the phrase ‘and has a natural basis consisting of elements of A’ [...]

The authors are regretful for submitting and approving the publication of incorrect Figure 4 in this article. Below is the corrected version along with the revised caption. The electronic version of the article has already been corrected.

RUS` IN THE INTERNATIONAL LIFE OF EUROPE IN VIII-X CENTURIES

The article attempts to outline the main aspects of the situation of Rus` land in the international life of Europe in the VIII-X centuries. Vikings have long been known East Europe, and the first contacts began far away before the famous «Іnvitation of the Varangians» in the «Povist mynulykh lit». Old Ladoga became the center of a conglomerate of the surrounding Ugro-Finnish-Varyag-Slavic tribes, and is known in Arabic sources as «Slavia». Versions of Askold’s origin are also considered and the hypothesis that he probably belonged to the Scylding dynasty is supported. Askold pursued a very active foreign policy, in particular, he signed an agreement with the Byzantine Empire and was baptized. It is likely that he commissioned his own chronicle, the corrected version of which was included in the oldest Chronicle reports. As for Dyrr, the most likely assumption today is that Dyrr lived before Askold, and he was the first to try to get rid of dependence on the Khazars Khaganate, and information from the «Povist mynulykh lit» is an insert of chroniclers. The article analyzes information from the «Annales Bertiniani», which report on the famous embassy to the Frankish Emperor Louis the Pious from the Kagan of the Rus`. This message caused a heated discussion about the localization of the Rus` Khaganate. The assumption of Omelyan Pritsak, who claimed that the Rus` Khaganate was located not far from the Khazar Khaganate, and Kyiv was founded by the Khazars, does not have sufficient scientific arguments in its favor today. The localization of the Rus` Khaganate in the North-East Rus` is also unconvincing, because in the IX century the rulers of Aldeigyuborg did not make campaigns to the Byzantine Empire, and did not use the title of Khagan, but called themselves konungs. Based on a various sources, in particular using the Geographus Bavarus and archaeological research, the version of localization of the Rus` Khaganate in the Dnipro region with the center in Kyiv was supported.

The Importance of Incorporating Lived Experience in Efforts to Reduce Australian Reincarceration Rates

It is widely acknowledged that ‘good policy’ should be informed by the people it most directly affects. However, learning from people with lived experiences in the criminal justice sector, such as people who have served time in prison, has received little attention. This article discusses the significance of and challenges related to capturing the voices of people who are currently serving time or have served time in prison. We argue that formalising the perspectives of these individuals into policymaking through co-design processes may be an important method for enhancing program responses to rising incarceration and reincarceration rates. *This is a corrected version of the original article published ‘Online First’ on February 17, 2021.
