A dual-scale stochastic analysis framework for creep failure considering microstructural randomness

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Weichen Kong, Yanwei Dai, Xiang Zhang, Yinghua Liu, | Summary: Creep failure under high temperatures is a complex multiscale and multi-mechanism issue involving inherent microstructural randomness. To investigate the effect of microstructures on the uniaxial/multiaxial creep failure, a dual-scale stochastic analysis framework is established to introduce the […]

Ultrafast Spontaneous Exciton Dissociation via Phonon Emission in BiVO$_4$

Posted by klaurent Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Stephen E. Gant, Antonios M. Alvertis, Christopher J. N. Coveney, Jonah B. Haber, Marina R. Filip | Summary: Monoclinic bismuth vanadate (m-BiVO$_4$) is a promising indirect band gap semiconductor for photoelectrochemical water splitting, yet the characteristics of its low-lying photoexcitations, or excitons, remain poorly understood. Here, […]

Rethinking Key-Value Cache Compression Techniques for Large Language Model Serving

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Wei Gao, Xinyu Zhou, Peng Sun, Tianwei Zhang, Yonggang Wen | Summary: Key-Value cache (texttt{KV} texttt{cache}) compression has emerged as a promising technique to optimize Large Language Model (LLM) serving. It primarily decreases the memory consumption of texttt{KV} texttt{cache} to reduce the computation cost. Despite the development […]

UniSep: Universal Target Audio Separation with Language Models at Scale

Posted by klaurent Cornell

Kavli Affiliate: Dan Luo | First 5 Authors: Yuanyuan Wang, Hangting Chen, Dongchao Yang, Weiqin Li, Dan Luo | Summary: We propose Universal target audio Separation (UniSep), addressing the separation task on arbitrary mixtures of different types of audio. Distinguished from previous studies, UniSep is performed on unlimited source domains and unlimited source numbers. We […]

Exponential quantum speedups in quantum chemistry with linear depth

Posted by dbos Berkeley

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Oskar Leimkuhler, K. Birgitta Whaley, , , | Summary: We prove classical simulation hardness, under the generalized $mathsf{P}neqmathsf{NP}$ conjecture, for quantum circuit families with applications in near-term quantum chemical ground state estimation. The proof exploits a connection to particle number conserving matchgate circuits with fermionic magic state […]
