6 Gbps real-time optical quantum random number generator based on vacuum fluctuation

open access: yes, 2019
We demonstrate a 6 Gbps real-time optical quantum random number generator by measuring vacuum fluctuation. To address the common problem that speed gap exists between fast randomness generation and slow randomness extraction in most high-speed real-time ...

The Myths of Blockchain Governance

open access: yesCorporate Governance: An International Review, EarlyView.
ABSTRACT Research Question/Issue Blockchain technology promises to revolutionize governance through strong commitments, trustlessness, and transparency. This paper examines how these promises have failed to materialize in practice. Research Findings/Insights Drawing on case evidence from major blockchains, including Bitcoin and Ethereum, I argue that ...

On the Theory of Spatial and Temporal Locality [PDF]

open access: yes, 2005
This paper studies the theory of caching and temporal and spatial locality. We show the following results: (1) hashing can be used to guarantee that caches with limited associativity behave as well as fully associative cache; (2) temporal locality cannot

Simple proof of confidentiality for private quantum channels in noisy environments

open access: yes, 2019
Complete security proofs for quantum communication protocols can be notoriously involved, which convolutes their verification, and obfuscates the key physical insights the security finally relies on.

The Drivers of Science Referenced in US EPA Regulatory Impact Analyses: Open Access, Professional Popularity, and Agency Involvement

open access: yesRegulation &Governance, EarlyView.
ABSTRACT We perform bibliometric analysis on documents for 255 Regulatory Impact Analyzes (RIAs) prepared by the US Environmental Protection Agency (EPA) from 1980 through 2024. Using a series of automated information extraction methods, we extract references from these documents and match them to bibliographic records.

Finding the Words: How Does the Aging Brain Process Language? A Focused Review of Brain Connectivity and Compensatory Pathways

open access: yesTopics in Cognitive Science, EarlyView.
Abstract As people age, there is a natural decline in cognitive functioning and brain structure. However, the relationship between brain function and cognition in older adults is neither straightforward nor uniform. Instead, it is complex, influenced by multiple factors, and can vary considerably from one person to another.

Separating hash families with large universe

open access: yesJournal 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)}

Securing End‐To‐End Encrypted File Sharing Services With the Messaging Layer Security Protocol

open access: yesConcurrency and Computation: Practice and Experience, Volume 37, Issue 27-28, 25 December 2025.
ABSTRACT Secure file sharing is essential in today's digital environment, yet many systems remain vulnerable: if an attacker steals client keys, they can often decrypt both past and future content. To address this challenge, we propose a novel file‐sharing architecture that strengthens post‐compromise security while remaining practical.

De Novo Whole Genome Assemblies of Unusual Case‐Making Caddisflies (Trichoptera) Highlight Genomic Convergence in the Composition of the Major Silk Gene (h‐fibroin)

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 7, Page 442-453, November 2025.
The major silk gene, h‐fibroin, was annotated in high‐quality genomes of two unusual case‐making Trichoptera. H‐Fibroin of Limnocentropus insolitus shows a similar amino acid composition to other case‐making species, while the amino acid composition of h‐fibroin of Phryganopsyche brunnea resembles that of retreat‐making species.

pTx‐Pulseq in hybrid sequences: Accessible and advanced hybrid open‐source MRI sequences on Philips scanners

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 5, Page 1946-1962, November 2025.
Abstract Purpose To enhance the accessibility of advanced pulse sequences, or parts thereof, through the open‐source Pulseq framework. This work extends the Pulseq framework to Philips MRI systems and incorporates dynamic parallel‐transmit (pTx) capabilities within the constraints of the existing Pulseq format.
