Parametric Markov Chains: PCTL Complexity and Fraction-free Gaussian Elimination [PDF]
Electronic Proceedings in Theoretical Computer Science, 2017 Parametric Markov chains have been introduced as a model for families of stochastic systems that rely on the same graph structure, but differ in the concrete transition probabilities. The latter are specified by polynomial constraints for the parameters.

Generating and Employing Witness Automata for ACTLW Formulae
IEEE Access, 2022 When verifying the validity of a formula in a system model by a model checker, a common feature is the generation of a linear witness or counterexample, which is a computation path usually showing a single reason why the formula is valid or, respectively,

A Counting Logic for Structure Transition Systems [PDF]
, 2012 Quantitative questions such as "what is the maximum number of tokens in a place of a Petri net?" or "what is the maximal reachable height of the stack of a pushdown automaton?" play a significant role in understanding models of computation. To study such

Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture
Advanced Healthcare Materials, EarlyView.This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

A Case Study on Formal Verification of Self-Adaptive Behaviors in a Decentralized System [PDF]
Electronic Proceedings in Theoretical Computer Science, 2012 Self-adaptation is a promising approach to manage the complexity of modern software systems. A self-adaptive system is able to adapt autonomously to internal dynamics and changing conditions in the environment to achieve particular quality goals.

Verifying the Smart Contracts of the Port Supply Chain System Based on Probabilistic Model Checking
Systems, 2022 Port supply chains play a very important role in the process of economic globalization. Lack of trust of the mechanism is the main factor in restricting the development of port supply chains.

QUANTUM COMPUTATION TREE LOGIC — MODEL CHECKING AND COMPLETE CALCULUS [PDF]
International Journal of Quantum Information, 2008 Logics for reasoning about quantum states and their evolution have been given in the literature. In this paper, we consider quantum computation tree logic (QCTL), which adds temporal modalities to exogenous quantum propositional logic. We give a sound and complete axiomatization of QCTL and combine the standard CTL model-checking algorithm with the ...

Néel Tensor Torque in Polycrystalline Antiferromagnets
Advanced Materials, EarlyView.This work introduces a Néel tensor torque based on a rank‐two symmetric tensor capturing spin correlations in a polycrystalline antiferromagnet. It shows the Néel tensor can be shaped and reshaped through the spin‐orbit torque (SOT) technique, enabling field‐free SOT switching with a specific polarity of the adjacent ferromagnet. This discovery opens a

Advanced Materials, EarlyView.This study demonstrates a monolithic perovskite OELG device that performs all eight logic operations, including XOR and XNOR, without external bias. Enabled by trap‐engineered MAPbI3:PLL and dual photogates, it achieves reconfigurable logic and parallel decoding of amplitude–frequency signals, supporting scenario‐configured logic‐level separation for ...
