The monopotassium salt of the ligand of a Ziegler–Natta catalyst [PDF]

open access: yes, 1993
The anion of dipotassium (tert-butylamino)-dimethyl(tetramethylcyclopentadienyl)silanediide can coordinate to transition metals to form precursors for single-component Ziegler-Natta polymerization catalysts.

Security and Performance Analyses of Post-Quantum Digital Signature Algorithms and Their TLS and PKI Integrations

open access: yesCryptography
Quantum computing challenges the mathematical problems anchoring the security of the classical public key algorithms. For quantum-resistant public key algorithms, the National Institute of Standards and Technology (NIST) has undergone a multi-year ...

Differential Fault Attacks on Deterministic Lattice Signatures

open access: yesTransactions on Cryptographic Hardware and Embedded Systems, 2018
In this paper, we extend the applicability of differential fault attacks to lattice-based cryptography. We show how two deterministic lattice-based signature schemes, Dilithium and qTESLA, are vulnerable to such attacks.

A blockchain-based hybrid encryption technique with anti-quantum signature for securing electronic health records

open access: yesComplex & Intelligent Systems
Electronic health records (EHRs) are important for the efficient management of healthcare data. However, Healthcare data travels across an open route, i.e., the Internet, making EHR security a difficult process to do. This puts healthcare data vulnerable

Optimizing Dilithium Implementation with AVX2/-512

open access: yesACM Transactions on Embedded Computing Systems
Dilithium is a signature scheme that is currently being standardized to the Module-Lattice-Based Digital Signature Standard by NIST. It is believed to be secure even against attacks from large-scale quantum computers based on lattice problems.

Dilithium disodium nickel(II) cyclohexaphosphate dodecahydrate, Li2Na2NiP6O18·12H2O

open access: yesActa Crystallographica Section E, 2012
The crystal structure of Li2Na2NiP6O18·12H2O is characterized by the presence of six-membered P6O186− phosphate ring anions (internal symmetry -1) having a chair conformation and three different cations, viz.

^(13)C, ^1H, and ^2H NMR Observation of Trideuterated Cyclopropylmethyl-Cyclobutyl Carbocation: A Configurationally Stable Species [PDF]

open access: yes, 1984
With the increasing power and sophistication of experimental and theoretical methods for assigning chemical structures, it seems almost incredible that the structure of any reasonably stable organic entity with a small number of carbons could remain ...

Comparative study of four immortalised human brain capillary endothelial cell lines, hCMEC/D3, hBMED, TY10, and BB19, and optimization of culture conditions, for an in vitro blood-brain barrier model for drug permeability studies [PDF]

open access: yes, 2013
BACKGROUND: Reliable human in vitro blood–brain barrier (BBB) models suitable for high-throughput screening are urgently needed in early drug discovery and development for assessing the ability of promising bioactive compounds to overcome the BBB.
