Adaptive Observer for Coupled Wave PDE and Infinite ODE With Sampled Data and Unknown Input: Application to Brain Hemodynamics Estimation

International Journal of Adaptive Control and Signal Processing, EarlyView.
This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.

Cryptanalysis of Selected ARX-Based Block Ciphers

Vietnam Journal of Computer Science
The security of digital communication and information systems is mostly dependent on block ciphers. ARX-based ciphers are widely used due to their simplicity and efficiency.

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

Advanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Accuracy and applicability of periodontitis risk assessment tools: A critical appraisal

Periodontology 2000, EarlyView., 2023
Abstract Currently, periodontal risk assessment finds application at first visit (to identify individuals at high risk of either disease incidence, if still healthy, or disease progression, if already diseased) as well as at patient monitoring after active treatment and enrolment in a supportive periodontal care program.

Algebraic Side-Channel Attacks [PDF]

, 2009
In 2002, algebraic attacks using overdefined systems of equa- tions have been proposed as a potentially very powerful cryptanalysis technique against block ciphers.

Traction Force Microscopy for Viscoelastic Substrates: A Semi‐Analytical Method

Advanced Science, EarlyView.
A semi‐analytical viscoelastic traction force microscopy framework is introduced for quantifying time‐resolved cell tractions on flat finite‐thickness substrates. The method generalizes elastic traction force microscopy to Generalized Maxwell materials, identifies when elastic approximations remain valid and, when they do not, shows that inferred ...

Class of constructions of even variables Boolean function with optimum algebraic immunity

Tongxin xuebao, 2009
A second order recursive construction of even variables Boolean function with optimum algebraic immunity was proposed.It could be observed that the constructed Boolean functions have well cryptographic properties,such as good balance,high algebraic ...

Physics‐Constrained Constitutive Learning of Rate‐Limiting Timescales for Efficient Hydrogen‐Based Direct Reduction for Green Steel Making

Advanced Science, EarlyView.
A conversion‐resolved constitutive framework is developed for the hydrogen‐based direct reduction of iron oxide pellets. Effective reaction and transport timescales are inferred directly from measured trajectories and mapped against operating conditions, pellet architecture, and composition. The analysis reveals how late‐stage transport control emerges

Algebraic attacks using SAT-solvers

Groups – Complexity – Cryptology, 2010
An algebraic attack on a cryptosystem consists of transforming the problem into the solution of a system of polynomial equations, usually over a finite field. The paper ``Algebraic attacks using SAT-solvers'' discusses different ways to efficiently transform the polynomial system into a logical clause.
