A Method for Detecting Anomalies in WebAssembly Using Categorical Data HEINRICH, TIAGO; WILL, NEWTON CARLOS; OBELHEIRO, RAFAEL; Carlos Alberto Maziero SN Computer Science, v. 7, n. 1, p. 68-70, 2026 DOI Palavra-chave: WebAssembly; Detecção de intrusão; Segurança de sistemas Áreas do conhecimento: Ciências Exatas e da Terra; Ciência da Computação; Sistemas de Computação; Arquitetura de Sistemas de Computação resumo ... The security of Web services for both users and developers is crucial; given that WebAssembly is an emerging format that has seen increasing attention in this environment over the years, new security measures are necessary. Despite this, intrusion detection solutions for WebAssembly applications are mostly confined to static binary analysis. We introduce an innovative method for dynamic WebAssembly intrusion detection through data categorization and machine learning. Our method analyzes communication data extracted from the WebAssembly sandbox to more effectively capture the behavior of applications. Our approach was validated through two strategies, both online and offline, to evaluate the effectiveness of categorical data for intrusion detection. The results obtained demonstrate that both strategies are viable for WebAssembly intrusion detection, showing a high detection rate with low false-negative and false-positive rates.
A quasi-set theory without atoms and its application to a quantum ontology of properties D. KRAUSE; JORGE, JUAN PABLO; LOMBARDI, OLIMPIA Synthese (Dordrecht.

One of the main ontological challenges posed by quantum mechanics is the problem of the indistinguishability of so-called “identical” particles, that is, particles that share the same state-independent properties. In the framework of this philosophical problem, a quasi-set theory was formulated to provide a proper metalanguage to deal with quantum indistinguishability; this theory included certain Urelemente called m-atoms, representing essentially indistinguishable objects. In turn, over the last two decades, the Modal Hamiltonian Interpretation proposed an ontology of properties, totally devoid of objects, where quantum systems are bundles of instances of universal properties. Therefore, the original quasi-set theory, with its m-atoms, does not adequately reflect the structure of an ontology devoid of objects. The purpose to the present article is to introduce a new quasi-set theory that does not include atoms at all: elementary items correspond to properties and are also represented by quasi-sets, which can be only numerically different. The final aim is to apply this new quasi-set theory to the MHI ontology.

Global Hypoellipticity for Involutive Systems on Non-Compact Manifolds CORIASCO, SANDRO; Alexandre Kirilov; Wagner Augusto Almeida de Moraes.; TOKORO, PEDRO MEYER JOURNAL OF GEOMETRIC ANALYSIS, v. 36, n. 1, p. 22 2026 DOI Palavra-chave: Global Hypoellipticity; Involutive structures; Scattering manifolds; Differential forms Áreas do conhecimento: Ciências Exatas e da Terra; Matemática; Análise; Equações Diferenciais Parciais; Ciências Exatas e da Terra; Matemática; Análise; Equações Diferenciais Parciais resumo ... We study the global hypoellipticity of the operator $$\mathbb {L} = \textrm{d}_t + \sum _{k=1}^m \omega _k \wedge \partial _{x_k}$$ , defined on differential forms over product manifolds of the form $$M \times \mathbb {T}^m$$ , where M is a non-compact manifold, given by the interior of a scattering manifold, and $$\omega _1,\dots ,\omega _m$$ are smooth closed 1-forms on M. Extending previous results obtained in the compact setting, we characterize the global hypoellipticity of $$\mathbb {L}$$ in terms of arithmetic properties of the forms $$\omega _1,\dots ,\omega _m$$ . The analysis relies on microlocal techniques, adapted to the scattering setting, and a version of the Hodge Theorem for scattering manifolds.
