Neuromorphic Light‐Responsive Organic Matter for in Materia Reservoir Computing
Advanced Materials, EarlyView.In this work we show that light‐responsive adaptive organic matter can store and process information at the matter level, and emulate neuromorphic functionalities such as short term memory, long term memory and visual memory. Besides demonstrating that material dynamics can be exploited for spatio‐temporal event detection and motion perception, we show

On the first fall degree of summation polynomials
Journal of Mathematical Cryptology, 2019 We improve on the first fall degree bound of polynomial systems that arise from a Weil descent along Semaev’s summation polynomials relevant to the solution of the Elliptic Curve Discrete Logarithm Problem via Gröbner basis algorithms.

Advanced Materials, EarlyView.A 3D‐printed self‐powered auxetic mechanoluminescent photonic skin for underwater communication and safety monitoring is introduced. Its auxetic structures, with a negative Poisson's ratio, ensure exceptional conformability to curved surfaces, enhancing adaptability to dynamic underwater environments.

Blind Proxy Re-Signature Scheme Based on Isomorphisms of Polynomials
IEEE Access, 2018 Most of the existing blind proxy re-signature schemes are designed based on the traditional public key cryptosystems, whose security relies on the hardness of big integer factoring, discrete logarithm, elliptic curve discrete logarithm, and so on ...

Discrete Logarithm in Galois Rings [PDF]
Mathematics and Statistics, 2018 Since Galois rings are the generalization of Galois fields, the question we tried to answer is: How to move from the discrete logarithm in Galois fields to the one in Galois rings? That concept of the discrete logarithm in Galois rings is a little bit different from the one in Galois fields.

Synthetic Chromatophores for Color and Pattern Morphing Skins
Advanced Materials, EarlyView.Cephalopods use chromatophore organs (muscle‐actuated pigment sacs) to alter their skin color and pattern. Synthetic chromatophores, which closely mimic the mechano‐optical process found in cephalopods using stimuli‐responsive microscale hydrogel actuators, are reported.

Advanced Materials Interfaces, EarlyView.This study investigates the plasmonic properties and biosensing capabilities of a nanocomposite incorporating Cu and Ag nanoparticles for detecting anti‐DbpA antibodies associated with Lyme disease. The enhanced LSPR response is explained through FDTD simulations of Cu–Ag near‐field interactions and increased surface roughness.

Post-quantum signature algorithms based on the hidden discrete logarithm problem [PDF]
Computer Science Journal of Moldova, 2018 New options of the hidden discrete logarithm problem are proposed as cryptographic primitive of the post-quantum signature algorithms. Two signature schemes using computations in finite non-commutative algebras with associative multiplication operation

On the discrete logarithm problem
, 2008 Let $p>2$ be prime and $g$ a primitive root modulo $p$. We present an argument for the fact that discrete logarithms of the numbers in any arithmetic progression are uniformly distributed in $[1,p]$ and raise some questions on the subject.

Soft ULC Microgels at the Interface Interact and Flow as Hertzian‐Like Colloids
Advanced Materials Interfaces, EarlyView.Monolayers of soft ULC microgels, studied combining interfacial rheology, AFM and computer simulations, exhibit isoelastic points. At these points, the measured stiffness of the monolayer remains constant despite large differences in particle concentration.
