Slow‐to‐Fast Transition and Shear Localization in Accelerating Creep of Clayey Soil

Geophysical Research Letters
Accelerating creep before catastrophic failure commonly follows a power‐law velocity‐acceleration relationship, with the exponent typically near 2 but often evolving from 1 to 2 at a certain point, indicating a dynamic transition.

Reduced-Precision and Reduced-Exponent Formats for Accelerating Adaptive Precision Sparse Matrix–Vector Product

Mixed precision algorithms aim at taking advantage of the performance of low precisions while maintaining the accuracy of high precision. In particular adaptive precision algorithms dynamically adapt at runtime the precisions used for different variables or operations. For example Graillat et al (2023) have proposed an adaptive precision sparse matrix--

Persistence and First-Passage Properties in Non-equilibrium Systems

, 2013
In this review we discuss the persistence and the related first-passage properties in extended many-body nonequilibrium systems. Starting with simple systems with one or few degrees of freedom, such as random walk and random acceleration problems, we ...

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Survival of a Diffusing Particle in a Transverse Shear Flow: A First-Passage Problem with Continuously Varying Persistence Exponent

, 2004
We consider a particle diffusing in the y-direction, dy/dt=\eta(t), subject to a transverse shear flow in the x-direction, dx/dt=f(y), where x \ge 0 and x=0 is an absorbing boundary.

Fast scrambling in holographic Einstein-Podolsky-Rosen pair

Journal of High Energy Physics, 2017
We demonstrate that a holographic model of the Einstein-Podolsky-Rosen pair exhibits fast scrambling. Strongly entangled quark and antiquark in N $$ \mathcal{N} $$ = 4 super Yang-Mills theory are considered.

From Quarter to All: Accelerating Speculative LLM Decoding via Floating-Point Exponent Remapping and Parameter Sharing

Large language models achieve impressive performance across diverse tasks but exhibit high inference latency due to their large parameter sizes. While quantization reduces model size, it often leads to performance degradation compared to the full model. Speculative decoding remains lossless but typically incurs extra overheads.
