‘Developing a Culture of Cybersecurity’
“In a prelude to the invasion of Ukraine in 2022, Russian hackers probed and attacked Ukrainian computer networks to find vulnerabilities and exfiltrate information that might be useful in future conflicts. … As we broadened our investigation beyond NotPetya to include other cyberattacks and hacking incidents, we were able to find a consistent pattern of cultural failures linked to misaligned incentives, a disconnect between top management and technical personnel, and a general lack of awareness and engagement of the existential threat posed by cyberattacks.”

‘Non-Volatile Magnon Transport in a Single Domain Multiferroic’
“Antiferromagnets have attracted significant attention in the field of magnonics, as promising candidates for ultralow-energy carriers for information transfer for future computing. … In multiferroics such as BiFeO3 the coupling between antiferromagnetic and polar order imposes yet another boundary condition on spin transport. Thus, understanding the fundamentals of spin transport in such systems requires a single domain, a single crystal. We show that through Lanthanum (La) substitution, a single ferroelectric domain can be engineered with a stable, single-variant spin cycloid, controllable by an electric field.” Find the paper and full list of authors in Nature Communications.

‘Psychophysics of Neon Color Spreading: Chromatic and Temporal Factors Are not Limiting’
“Neon color spreading (NCS) is an illusory color phenomenon that provides a dramatic example of surface completion and filling-in. Numerous studies have varied both spatial and temporal aspects of the neon-generating stimulus to explore variations in the strength of the effect. Here, we take a novel, parametric, low-level psychophysical approach to studying NCS. … There is no evidence in this study that the processes underlying NCS are slower than the low-level processes of simple flicker detection. These results point to relatively fast mechanisms, not slow diffusion processes, as the substrate for NCS.” Find the paper and authors list in Vision…

‘Strategic Behavior of Large Language Models and the Role of Game Structure Versus Contextual Framing’
“This paper investigates the strategic behavior of large language models (LLMs) across various game-theoretic settings, scrutinizing the interplay between game structure and contextual framing in decision-making. We focus our analysis on three advanced LLMs—GPT-3.5, GPT-4, and LLaMa-2—and how they navigate both the intrinsic aspects of different games and the nuances of their surrounding contexts. Our results highlight discernible patterns in each model’s strategic approach. GPT-3.5 shows significant sensitivity to context but lags in its capacity for abstract strategic decision making.” Find the paper and full list of authors in Nature: Scientific Reports.

‘Cosmologically Consistent Analysis of Gravitational Waves From Hidden Sectors’
“Production of gravitational waves in the early Universe is discussed in a cosmologically consistent analysis within a first-order phase transition involving a hidden sector feebly coupled with the visible sector. Each sector resides in its own heat bath leading to a potential dependent on two temperatures and on two fields: one a standard model Higgs field and the other a scalar arising from a hidden sector 𝑈(1) gauge theory. A synchronous evolution of the hidden and visible sector temperatures is carried out from the reheat temperature down to the electroweak scale.” Find the paper and authors list in Physical Review D.
