Code-based Masking: From Fields to Bits Bitsliced Higher-Order Masked SKINNY

Transactions on Cryptographic Hardware and Embedded Systems
Masking is one of the most prevalent and investigated countermeasures against side-channel analysis. As an alternative to the simple (e.g., additive) encoding function of Boolean masking, a collection of more algebraically complex masking types has ...

Identification and Structural Elucidation of a New Synthetic Cannabinoid, MDMB‐5′Br‐PINACA, in Seized Herbal Materials

Drug Testing and Analysis, EarlyView.
MDMB‐5Br‐PINACA, a novel synthetic cannabinoid, was identified and structurally characterized in seized herbal products using GC‐MS, LC‐HRMS, and NMR. The discovery underscores ongoing diversification of SCs and the need for vigilant surveillance.

Activation and Derivatization of Perfluoro(methyl Vinyl Ether) by a Rh(I) Germyl Complex

European Journal of Inorganic Chemistry, EarlyView.
Treatment of the rhodium (I) germyl complex [Rh(GePh3)(PEt3)3] with perfluoro(methyl vinyl ether) [PMVE] resulted in CO and CF bond cleavage and decarbonylation reactions, to yield trans‐[Rh(CFCF2)(CO)(PEt3)2] and germylated species including fluorogermane FGePh3, and fluoroalkene CF(GePh3)CF2.

Dinuclear Rhodium(I)–N‐Heterocyclic Carbene Complexes as Alkyne Hydropyridonation Catalysts

European Journal of Inorganic Chemistry, EarlyView.
Catalyst Improvement by NHC tuning: A series of new RhI–NHC dinuclear complexes has been revealed as efficient alkyne hydropyridonation catalysts. 333053IMes complex displays the highest reactivity of the series, suggesting that a moderate steric demand combined with balanced σ‐donation facilitates precatalyst activation and substrate exchange.

Efficient Length Doubling From Tweakable Block Ciphers

IACR Transactions on Symmetric Cryptology, 2017
We present a length doubler, LDT, that turns an n-bit tweakable block cipher into an efficient and secure cipher that can encrypt any bit string of length [n..2n − 1].

Wonder as a Gateway to Science Meaning‐Making: Primary Pupils’ Narrative Journeys

Future in Educational Research, EarlyView.
ABSTRACT This study explores how wonder fosters transformative learning in science education for pupils (11–12 years old), creating meaning about cycles in nature. As an emotional and epistemic trigger, wonder may bridge everyday experiences with abstract scientific concepts by stimulating curiosity and creativity. Through a narrative writing task, the

Privacy-preserving logistic regression training

BMC Medical Genomics, 2018
Background Logistic regression is a popular technique used in machine learning to construct classification models. Since the construction of such models is based on computing with large datasets, it is an appealing idea to outsource this computation to a

Transannular O‐Heterocyclization Reactions of Cyclododeca‐1,5,9‐triene Derivatives: A New Concept for the Preparation of Key Intermediates for Total Syntheses of Annonaceous Acetogenins

Helvetica Chimica Acta, EarlyView.
Four stereogenic centers are formed diastereoselectively in one step from a cyclic (E,E)‐1,5‐diene system using an electrophilic addition reaction. Subsequent ozonolytic cleavage of the intact Z‐double bond, followed by intramolecular nucleophilic substitution, yields an octahydroterfurandione with a threo,cis,threo configuration, an arrangement found ...
