Structure-Exploiting ADMM for Low-Complexity Finite-Blocklength Beamforming in Cellular IoT Networks
Asim Ihsan, Muhammad Asif, Ali Arshad Nasir +3
Ultra-reliable and low-latency communication (URLLC) is essential for mission-critical cellular Internet of Things (IoT) applications requiring reliable short-packet transmission a…
A reduced-order analysis for multi-reflection-driven laser absorptance in vaporization-induced cavities
Haolin Liu, Haoran Shi, Xuzhe Zeng +4
Multiple internal reflections enhance laser absorption in vaporization-induced cavities, but connecting ray histories, cavity geometry, and absorptance typically requires full ray…
FLARE++: Low-rank attention with dynamic attention routing
Vedant Puri, Yongjie Jessica Zhang, Levent Burak Kara
Full self-attention is a strong token mixer for PDE surrogates on irregular domains, but its quadratic cost limits its use on large problems. Latent-space attention methods such as…
Aeroacoustic signatures reveal fast transient dynamics of vapor-jet-driven cavity oscillations in metallic additive manufacturing
Haolin Liu, S. Kiana Naghibzadeh, Zhongshu Ren +12
Aeroacoustic emissions from intense evaporation are widely measured yet often treated as noisy byproducts and used mainly in empirical monitoring. Here, we show that airborne sound…
Accelerated Discovery of Cryoprotectant Cocktails via Multi-Objective Bayesian Optimization
Daniel Emerson, Nora Gaby-Biegel, Purva Joshi +3
Designing cryoprotectant agent (CPA) cocktails for vitrification is challenging because formulations must be concentrated enough to suppress ice formation yet non-toxic enough to p…
FlowSSC: Universal Generative Monocular Semantic Scene Completion via One-Step Latent Diffusion
Zichen Xi, Hao-Xiang Chen, Nan Xue +5
Semantic Scene Completion (SSC) from monocular RGB images is a fundamental yet challenging task due to the inherent ambiguity of inferring occluded 3D geometry from a single view.…
Heterogeneous Metamaterials Design via Multiscale Neural Implicit Representation
Hongrui Chen, Liwei Wang, Levent Burak Kara
Metamaterials are engineered materials composed of specially designed unit cells that exhibit extraordinary properties beyond those of natural materials. Complex engineering tasks…
Airborne acoustic emission enables sub-scanline keyhole porosity quantification and effective process characterization for metallic laser powder bed fusion
Haolin Liu, David Guirguis, Xuzhe Zeng +7
Keyhole-induced (KH) porosity, which arises from unstable vapor cavity dynamics under excessive laser energy input, remains a significant challenge in laser powder bed fusion (LPBF…
FLARE: Fast Low-rank Attention Routing Engine
Vedant Puri, Aditya Joglekar, Sri Datta Ganesh Bandreddi +4
The quadratic complexity of self-attention limits the scalability of transformers on long sequences. We introduce Fast Low-rank Attention Routing Engine (FLARE), a token-mixing ope…
Attention to Detail: Fine-Scale Feature Preservation-Oriented Geometric Pre-training for AI-Driven Surrogate Modeling
Yu-hsuan Chen, Jing Bi, Cyril Ngo Ngoc +3
AI-driven surrogate modeling has become an increasingly effective alternative to physics-based simulations for 3D design, analysis, and manufacturing. These models leverage data-dr…
