Summary: In this paper, a universally composable 1-out-of-N oblivious transfer protocol with low communication is proposed. This protocol achieves full simulation security based on the Mod-LWR assumption. By combining random OT with the key exchange protocol and the authentication encryption algorithm, it achieves universally composable security in the ROM model. The protocol is proven to resist static adversary attacks by simulating all corruption cases. Through computer simulation and mathematical derivation, it is shown to be practical and efficient with low communication costs.

Summary: New constraints have been identified for Israel-Stewart-like theories of fluid dynamics to be causal far from equilibrium. Sufficient conditions have also been presented to ensure causality, local existence, and uniqueness of solutions in these theories. The findings provide fundamental constraints on the magnitude of viscous corrections in fluid dynamics far from equilibrium, without simplifying symmetry or near-equilibrium assumptions.

Summary: In this paper, the authors address the issue of composable security in finite-sized Gaussian quantum networks, with generally untrusted nodes. They propose a general methodology for parameter estimation based on shared data and demonstrate its effectiveness using a chain of identical quantum links as an example. Additionally, they discuss the potential of quantum amplifier-assisted chains to surpass the fundamental limits and highlight the need for further research in network/chain designs.

Summary: The performance of federated learning systems is constrained by communication costs and training variance. To address the communication overhead problem, techniques such as model compression, partial device participation, and periodic aggregation have been introduced. However, federated learning faces challenges in data heterogeneity and data privacy. This article theoretically and experimentally investigates the tradeoffs between communication costs and training variance in a resource-constrained federated system and explores the role of communication reduction techniques in a differentially private setting.

Summary: In this paper, a notion of causality is defined on a (1 + 1)-dimensional kappa-Minkowski space-time using the framework of Lorentzian noncommutative geometry. It is shown that this notion allows specific causal relations, but is limited by a quantum generalization of the traditional speed of light limit.

Summary: Subversion attacks undermine the security of cryptographic protocols by replacing an honest party's implementation with a leaky one. Existing techniques for designing secure cryptographic protocols against subversion attacks do not guarantee security in the setting where multiple protocols run concurrently. This paper provides a foundation of reverse firewalls in the universal composability framework to address this limitation. The authors propose a methodology for designing subversion-resilient protocols by sanitizing different sub-components.

Summary: This paper proposes a visual analytics approach to help data custodians generate multiple private charts while maintaining user-preferred patterns. Pattern constraints are introduced to model users' preferences over data patterns and incorporated into the Bayesian network-based Differential Privacy (DP) model PriVis. A prototype system, DPVisCreator, is developed to assist data custodians in implementing the approach. The effectiveness of the approach is demonstrated through quantitative evaluation of pattern utility, case studies, and semi-structured expert interviews.

Summary: A new colorimetric method for monitoring the progress of nucleic acid aptamer selection is described, utilizing rolling circle amplification (RCA) and the activity of G-quadruplex/hemin DNAzyme. The method provides a quantitative measurement of SELEX progress by analyzing the signal generated by DNA pool bound to their target.

Summary: In this article, the distribution of bipartite states in a quantum network limited by timing constraints is studied, exploring various tasks that may arise in this context with a focus on achievability in settings with limited communication. Partial results are provided in the case where two-way communication is allowed, building on prior work on summoning single and bipartite systems.

Summary: In this study, the perception of physical and animated motion in bouncing-like scenarios was explored through four experiments. The results showed that the visual information available in the scene strongly influenced the extent to which observers relied on realistic representations of physical constraints. Additionally, perceptual constraints such as preference for smaller simulated gravitational attraction and perceived temporal contiguity also affected bouncing impressions. The experiments also indicated that the visual system can fill-in missing elements in the scene and that a passive object can be perceived as the direct cause of an active object's motion behavior in bouncing scenarios, contrary to current causal perception theories.

Summary: This paper models and analyzes the Signal end-to-end messaging protocol within the UC framework. It formulates an ideal functionality capturing the secure messaging properties of Signal and models the main components of the Signal architecture as individual ideal functionalities. The paper also demonstrates how these functionalities can be realized using standard cryptographic primitives under minimal hardness assumptions.

Summary: It has been recently demonstrated that the dispersion relations describing singularities of retarded two-point functions in causal quantum field theories always satisfy the fundamental inequality Im w <= |Im k|, and that various rigorous bounds on transport coefficients can be derived from this inequality. In this study, we prove that the same inequality, Imw <= |Imk|, is a necessary condition for a fluid theory to be covariantly stable in all frames of reference. Therefore, the bounds on transport derived from causality in quantum field theory also serve as stability conditions in relativistic hydrodynamics. This close connection between bounds from causality and stability arises from the fact that covariant stability is only possible in the presence of causality. As an immediate application, we demonstrate that fluids with luminal speed of sound have vanishing viscosities.
