Drug Testing and Analysis, EarlyView.Waxy‐ or putty‐like materials has emerged as a novel drug preparation for synthetic cannabinoids and other drugs in UK prisons. An in vitro CB1 bioassay was used to evaluate the CB1 activating potential of MDMB‐INACA and extracts from eight seized samples. MDMB‐INACA had moderate efficacy but low potency at CB1.

Semi‐Paired Semi‐Supervised Deep Hashing for cross‐view retrieval
IET Computer Vision, EarlyView., 2022 In this study, a Semi‐Paired Semi‐Supervised Deep Hashing (SPSDH) is proposed. SPSDH is a novel end‐to‐end deep neural network model with high‐order affinity. A non‐local higher‐order affinity measure that better considers the multimodal neighbourhood structure. And a common representation to associate different modalities is introduced, which combined

Indifferentiability security of the fast wide pipe hash: Breaking the birthday barrier
Journal of Mathematical Cryptology, 2016 A hash function secure in the indifferentiability framework (TCC 2004) is able to resist all meaningful generic attacks. Such hash functions also play a crucial role in establishing the security of protocols that use them as random functions.

Online Supervised Sketching Hashing for Large-Scale Image Retrieval
IEEE Access, 2019 Online hashing methods have achieved a good tradeoff between the accuracy and the efficiency for learning the hash functions in the online settings. Compared to the stochastic gradient descent-based online hashing methods, the data sketching-based online

Cryptanalysis of the GOST Hash Function [PDF]
, 2008 In this article, we analyze the security of the GOST hash function. The GOST hash function, defined in the Russian standard GOST 34.11-94, is an iterated hash function producing a 256-bit hash value. As opposed to most commonly used hash functions such as MD5 and SHA-1, the GOST hash function defines, in addition to the common iterative structure, a ...

A preimage attack on reduced GIMLI‐HASH with unbalanced squeezing phase
IET Information Security, Volume 17, Issue 1, Page 66-79, January 2023., 2023 Abstract In Conference on Cryptographic Hardware and Embedded System 2017, Bernstein et al. proposed GIMLI, a 384‐bit permutation with 24 rounds, which aims to provide high performance on various platforms. In 2019, the full‐round (24 rounds) GIMLI permutation was used as an underlying primitive for building AEAD GIMLI‐CIPHER and hash function GIMLI ...
