High-Speed Privacy Amplification Algorithm Based on Two-Dimensional Cellular Automata in Quantum Key Distribution

IEEE Photonics Journal
Privacy amplification is a critical component in quantum key distribution (QKD) to eliminate eavesdropper information and distill unconditionally secure keys.

Separating hash families with large universe

Journal of Combinatorial Theory, Series A
Separating hash families are useful combinatorial structures which generalize several well-studied objects in cryptography and coding theory. Let $p_t(N, q)$ denote the maximum size of universe for a $t$-perfect hash family of length $N$ over an alphabet of size $q$. In this paper, we show that $q^{2-o(1)}

Undetected Error Bounds for Hybrid Integrity Protection Using Reed–Muller Codes, Algebraic Manipulation Detection, and Universal Hashing

Entropy
Ensuring information integrity requires not only reducing decoding errors but also reducing the probability that corrupted data are accepted as valid.

Recursive Grid Indexing for Fast Non‐Uniform Quantization Without Binary Search

Software: Practice and Experience, EarlyView.
ABSTRACT Purpose To present Recursive Grid Indexing (RGI), a practical software technique for accelerating non‐uniform quantization and predecessor queries without relying on binary search at any stage. Design/Methodology/Approach RGI replaces conventional logarithmic binary search with a recursive, low‐branching grid structure. The method constructs a

Indifferentiability of the Sponge Hash Family: New Attacks and the Optimal Construction

IACR Transactions on Symmetric Cryptology
The sponge construction is subject to an indifferentiability security bound of c/2 bits, where c denotes the capacity. For a given b-bit permutation, the sponge construction allows sacrificing the rate r = b − c to achieve the theoretically optimal ...

Advances in 4D Representation: Geometry, Motion, and Interaction

Computer Graphics Forum, EarlyView.
We survey 4D representation through three key pillars — geometry, motion, and interaction — offering a selective, representation‐centric perspective to guide researchers in choosing and customizing the right 4D representation for their tasks. Abstract We present a survey on 4D generation and reconstruction, a fast‐evolving subfield of computer graphics

MSI: A Mahalanobis‐Based Molecular Similarity Index for High‐Dimensional Embeddings

Molecular Informatics, Volume 45, Issue 9, September 2026.
MSI pairs continuous Mol2Vec embeddings with a covariance‐aware Mahalanobis metric (dM, θM) to overcome the ranking ties and bit‐density bias of Tanimoto fingerprints. Across five reference compounds, MSI resolves more distinct neighbors than ECFP4 + Tanimoto and its geometry tracks HOMO–LUMO gaps in QM9, despite no electronic training.

Hybrid Classical–Quantum Text Search Based on Hashing

Mathematics
The paper considers the problem of finding a given substring in a text. It is known that the complexity of a classical search query in an unordered database is linear in the length of the text and a given substring.

The three‐step test in international copyright—a global framework for generative AI training

American Business Law Journal, Volume 63, Issue 3, Page 265-298, Fall 2026.
Abstract The training of generative artificial intelligence (genAI) models involves the processing of large datasets, which often include copyrighted materials, thereby raising questions of copyright infringement. These questions tend to center on whether such use constitutes fair use or falls under text and data mining (TDM) exceptions.

God's Presence in the Aisle: How God Salience Encourages Preference for Ultra‐Processed Foods

Psychology &Marketing, Volume 43, Issue 8, Page 1859-1877, August 2026.
ABSTRACT God‐related cues are pervasive in consumers' daily lives, yet little research has examined how God salience shapes consumer food choices. Drawing on compensatory control theory and the literature on symbolic healing, we present findings from six studies, including a field experiment, demonstrating that high (vs.
