Information systems have widely been the target of malware attacks. Traditional signature-based malicious program detection algorithms can only detect known and are prone to evasion techniques such as binary obfuscation, while behavior-based approaches highly rely on training samples incur prohibitively high cost. To address limitations existing techniques, we propose MatchGNet, a heterogeneous Graph Matching Network model learn graph representation similarity metric simultaneously based...

In few-shot semantic segmentation (FSS), the key challenges are efficiently tuning interaction between support set and query distinguishing context, background, interfering items. To address these challenges, we propose prototype comparison networks for one-shot (OPCN) to capture details required FSS. Specifically, offer Fusion Interaction Module (FIM) improve performance by capturing correlation information features. Subsequently, Feature Enhancement (FEM), which aims enhance in features...

Marking mutations: Complete discrimination of 8-oxoguanosine (8-oxoG) from other nucleosides has been achieved with a new fluorescent probe, named "8-oxoG-clamp" (see picture). The complex structure between 8-oxoG-clamp and 8-oxoG was confirmed by 1H NMR titration 2D measurements. A preliminary investigation use detergent for solubilization indicates that may be applicable in aqueous media. Supporting information this article is available on the WWW under...

End-to-end semantic communications (ESC) rely on deep neural networks (DNN) to boost communication efficiency by only transmitting the semantics of data, showing great potential for high-demand mobile applications. We argue that central success ESC is robust interpretation conveyed at receiver side, especially security-critical applications such as automatic driving and smart healthcare. However, robustifying challenging extremely vulnerable physical-layer adversarial attacks due openness...

The widespread application of mobile robots holds significant importance for advancing social intelligence. However, as the complexity environment increases, existing Obstacle Avoidance Path Planning (OAPP) methods tend to fall into local optimal paths, compromising reliability and practicality. Therefore, based on Spider-Wasp Optimizer (SWO), this paper proposes an improved OAPP method called LMBSWO address these challenges. Firstly, learning strategy is introduced enhance diversity...

Recent advances in the causal analysis can accelerate incident response time, but only after a graph of attack has been constructed. Unfortunately, existing generation techniques are mainly offline and may take hours or days to respond investigator queries, creating greater opportunity for attackers hide their footprint, gain persistency, propagate other machines. To address that limitation, we present Swift, threat investigation system provides high-throughput causality tracking real-time...

The latent behavior of an information system that can exhibit extreme events, such as faults or cyber-attacks, is complex. Recently, the invariant network has shown to be a powerful way characterizing complex behaviors. Structures and evolutions invariance network, in particular, vanishing correlations, shed light on identifying causal anomalies performing diagnosis. However, due dynamic nature real-world systems, learning reliable new environment often requires continuous collecting...
