Intelligent Interaction Strategies for Context-Aware Cognitive Augmentation
Xiangrong, Zhu, Yuan Xu +4
Human cognition is constrained by processing limitations, leading to cognitive overload and inefficiencies in knowledge synthesis and decision-making. Large Language Models (LLMs)…
When Should Neural Data Inform Welfare? A Critical Framework for Policy Uses of Neuroeconomics
Yiven, Zhu
Neuroeconomics promises to ground welfare analysis in neural and computational evidence about how people value outcomes, learn from experience and exercise self-control. At the sam…
Gemini 2.5: Pushing the Frontier with Advanced Reasoning, Multimodality, Long Context, and Next Generation Agentic Capabilities
Gheorghe Comanici, Eric Bieber, Mike Schaekermann +3431
In this report, we introduce the Gemini 2.X model family: Gemini 2.5 Pro and Gemini 2.5 Flash, as well as our earlier Gemini 2.0 Flash and Flash-Lite models. Gemini 2.5 Pro is our…
Magentic-One: A Generalist Multi-Agent System for Solving Complex Tasks
Adam Fourney, Gagan Bansal, Hussein Mozannar +17
Modern AI agents, driven by advances in large foundation models, promise to enhance our productivity and transform our lives by augmenting our knowledge and capabilities. To achiev…
Sieve-SDP: a simple facial reduction algorithm to preprocess semidefinite programs
Yuzixuan, Zhu, Gabor Pataki +1
We introduce Sieve-SDP, a simple facial reduction algorithm to preprocess semidefinite programs (SDPs). Sieve-SDP inspects the constraints of the problem to detect lack of strict f…
Ribbonlength of folded ribbon unknots in the plane
Elizabeth Denne, Mary Kamp, Rebecca Terry +2
We study Kauffman's model of folded ribbon knots: knots made of a thin strip of paper folded flat in the plane. The ribbonlength is the length to width ratio of such a ribbon, and…
JCMT BISTRO survey: Magnetic Fields within the Hub-Filament Structure in IC 5146
Jia-Wei Wang, Shih-Ping Lai, Chakali Eswaraiah +130
We present the 850 m polarization observations toward the IC5146 filamentary cloud taken using the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) and its associated pola…
A Novel Design of Capacitive Plasmonic Near Field Transducer
Tianxiang Du, David E Laughlin, Jian-Gang +1
A near field transducer (NFT) is a key photonics component in heat assisted magnetic recording (HAMR) for the localized heating of the magnetic medium. In this work, we present a n…
Comparison of h-BN and graphene layers as grain boundary materials for granular FePt- thin films
B. S. D. Ch. S. Varaprasad, Chengchao Xu, Brandon Reese +3
Granular -FePt thin films with small columnar grains are essential for heat-assisted magnetic recording media. While hexagonal boron nitride(h-BN) has proven effective…
Understanding the growth of high-aspect-ratio grains in granular L10-FePt thin-film magnetic media
Chengchao Xu, Bing Zhou, Tianxiang Du +4
A systematic investigation has been performed to optimize the microstructure of granular thin film as recording media for heat-assisted magnetic recordin…
Bias sputtering of granular -FePt films with hexagonal boron nitride grain boundaries
Chengchao Xu, B. S. D. Ch. S Varaprasad, David E. Laughlin +2
In this paper, we present an experimental study of -FePt granular films with crystalline/amorphous boron nitride (BN) grain boundary materials for heat assisted magnet…
Ultralow thermal conductance across the [FePt/h-BN/FePt] interface
chengchao Xu, Enbo Zhang, Bo-Yuan Yang +4
Heat transfer in nanocomposite materials has attracted great interest for various applications. Multilayer structures provide an important platform to study interfacial thermal tra…
Reinforcement Learning for LLM Post-Training: A Survey
Zhichao Wang, Kiran Ramnath, Bin Bi +9
Large language models (LLMs) trained via pretraining and supervised fine-tuning (SFT) can still produce harmful and misaligned outputs, or struggle in domains like math and coding.…
Behavior of quantum coherence in the ultrastrong and deep strong coupling regimes of light-matter system
Yu-qiang Liu, Qiulin Long, Yi-jia Yang +12
The ultrastrong and deep strong coupling regimes exhibit a variety of intriguing physical phenomena. In this work, we utilize the Hopfield model of a two-mode bosonic system, with…
Aligned Multi Objective Optimization
Yonathan Efroni, Ben Kretzu, Daniel Jiang +4
To date, the multi-objective optimization literature has mainly focused on conflicting objectives, studying the Pareto front, or requiring users to balance tradeoffs. Yet, in machi…
