Countering Side-Channel Attacks With a Dynamic S-Box Based on Affine Transformations and Gold Sequences

IEEE Transactions on Very Large Scale Integration (VLSI) Systems
Advanced cryptographic devices employ multiscale countermeasures to bolster resilience against side-channel analysis (SCA). In masking-based defenses, secure substitution-boxes (S-boxes) and effective masking schemes are paramount. Additionally, the time-

Effects of Substitution Matrices, Trimming and Outliers on Alignments and Phylogenetic Tree Constructions of Big Dataset

International Conference on Transparent Optical Networks
The substitution matrix is important for the multiple sequence alignment (MSA). Thereafter the MSA is often subject to trimming and eliminating of detected outlier sequences.

Relative electron affinities of substituted benzophenones, nitrobenzenes, and quinones

Journal of the American Chemical Society, 1985
On determine les affinites electroniques de 53 molecules en mesurant les constantes d'equilibre des reactions de transfert d'electron en phase gazeuse du type A −• +B=B −• +A. On utilise un spectrometre a resonance cyclotronique ionique pour generer, stocker et detecter les radicaux anioniques moleculaires a des pressions inferieures a 1×10 −5 ...

Synthesis and adrenoceptor affinity of some highly polar .beta.-substituted catecholamines

Journal of Medicinal Chemistry, 1981
In order to assess the potential for sympathomimetic or sympatholytic activity within the series of catecholamine beta-sulfonates 3a-c, alpha- and beta-adrenoceptor binding affinities were determined using rat brain homogenate preparations. Furthermore, their potential for indirect activity was assessed by measurement of blockade of norepinephrine ...

Fibrin Affinity and Clearance of t-PA Deletion and Substitution Analogues

Thrombosis and Haemostasis, 1990
SummaryTo investigate structure-function relationships in tissue-type plasminogen activator (t-PA) we deleted the following domains in the heavy chain: a) The epidermal growth factor domain (t-PA del. G), b) the finger domain, and the epidermal growth factor domain (t-PA del. FG), and c) the finger, the epidermal growth factor and Kr-ingle 1 (1-PA del,

Alanine Substitutions in Calmodulin-binding Peptides Result in Unexpected Affinity Enhancement

Journal of Molecular Biology, 1996
Calmodulin is a calcium-binding protein that regulates a wide range of enzymes. It is also one of the few examples of a small protein capable of binding to peptides with very high affinity, and is therefore an interesting candidate for biotechnological applications and a good model system for studying how proteins associate.

Spare Parts Inventory Management with Substitution-Dependent Reliability

INFORMS journal on computing, 2018
Motivated to apply sustainable supply chain principles to air-pollution control systems, this paper presents a dynamic inventory-management approach where substitution is possible to maintain these systems’ equipment.

Characteristics of 8-substituted adenine nucleotide derivatives utilized in affinity chromatography

Archives of Biochemistry and Biophysics, 1975
Abstract Improved methods for the preparation of several 8-substituted adenine nucleotide derivatives are described. Enzymatic properties of these 8-substituted derivatives were investigated by steady state kinetic and inhibition studies. It was found that 8-(6-aminohexyl)-amino DPN+ and TPN+ exhibit relatively high affinity for most DPN+ and TPN ...
