Survey on Visualization of Information Diffusion over Networks

Computer Graphics Forum, EarlyView.
Abstract Information Diffusion (ID) describes how a value (e.g., a pathogen, a rumor, a packet) spreads through an underlying “medium” network of elements (e.g., a social or computer network). Understanding the information diffusion process is essential to predicting trends, controlling misinformation, and enhancing decision‐making as well as ...

An Algebraic Technique for Securing Applications Against Reverse Engineering Attacks

IEEE Access
Control flow flattening is a widely used software obfuscation technique that protects programs against reverse engineering attacks by transforming structured control flow into dispatcher-based execution. In this paper, we introduce a formal framework for

Counting equations in algebraic attacks on block ciphers

, 2010
This paper is about counting linearly independent equations for so-called algebraic attacks on block ciphers. The basic idea behind many of these approaches, e.g., XL, is to generate a large set of equations from an initial set of equations by ...

Optimal Healthcare Contracts: Theory and Empirical Evidence

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT In this paper, we investigate the contracts offered by a large healthcare purchaser to health service providers. Contracts are based on the DRG principle that all hospitalizations in a diagnosis group are reimbursed at the same rate. This principle is relaxed in practice, as in several cases, the amount reimbursed within each DRG exhibits ...

Lucid Dreaming Frequency Associated With Grey–White Matter Networks: An Exploratory Multimodal MRI Study

Journal of Sleep Research, EarlyView.
ABSTRACT Lucid dreaming, defined as the experience of becoming aware of dreaming while dreaming, offers a unique window into a state of consciousness characterised by a blending of the sensory vividness of REM sleep with the self‐awareness of wakefulness. While past functional imaging has shed light on the neural activity supporting lucid dreaming, the

Effective When Distinctive: The Role of Phonetic Similarity in Nested Dependency Learning Across Preschool Years

Language Learning, EarlyView.
Abstract Parallel tracking of distant relations between speech elements, so‐called nonadjacent dependencies (NADs), is crucial in language development but computationally demanding and acquired only in late preschool years. As processing of single NADs is facilitated when dependent elements are perceptually similar, we investigated how phonetic ...

strategies on algebraic attacks using sat solvers

, 2008
China Computer FederationSAT solvers are employed in algebraic attacks to stream ciphers in recent years. This attack describes a cipher by a boolean equation system in the initial state, and then converts the equation system into a SAT instance.

Navigating Supply Shocks: Sector Resilience and Production Prices Through Stochastic Input–Output Modeling

Mathematical Finance, EarlyView.
ABSTRACT This study develops a novel multivariate stochastic framework for assessing systemic risks, such as climate and nature‐related shocks, within production or financial networks. By embedding a linear stochastic fluid network, interpretable as a generalized vector Ornstein–Uhlenbeck process, into the production network of interdependent ...

Poseidon and Neptune: Gröbner Basis Cryptanalysis Exploiting Subspace Trails

IACR Transactions on Symmetric Cryptology
At the current state of the art, algebraic attacks are the most efficient method for finding preimages and collisions for arithmetization-oriented hash functions, such as the closely related primitives Poseidon/Poseidon2 and Neptune.
