Finite Element Method for Liquid Crystal Defect Minimization

Published:Dec 31, 2025 15:37

ArXiv

Analysis

This paper presents a numerical algorithm, based on the Alternating Direction Method of Multipliers and finite elements, to solve a Plateau-like problem arising in the study of defect structures in nematic liquid crystals. The algorithm minimizes a discretized energy functional that includes surface area, boundary length, and constraints related to obstacles and prescribed curves. The work is significant because it provides a computational tool for understanding the complex behavior of liquid crystals, particularly the formation of defects around colloidal particles. The use of finite elements and the specific numerical method (ADMM) are key aspects of the approach, allowing for the simulation of intricate geometries and energy landscapes.

ArXiv

Analysis

This paper addresses the challenge of efficient caching in Named Data Networks (NDNs) by proposing CPePC, a cooperative caching technique. The core contribution lies in minimizing popularity estimation overhead and predicting caching parameters. The paper's significance stems from its potential to improve network performance by optimizing content caching decisions, especially in resource-constrained environments.
Reference

“CPePC bases its caching decisions by predicting a parameter whose value is estimated using current cache occupancy and the popularity of the content into account.”

Local Rendezvous Hashing for Balanced Loads and Minimal Churn

Published:Dec 29, 2025 12:52
1 min read
ArXiv

Analysis

This paper introduces Local Rendezvous Hashing (LRH) as a novel approach to consistent hashing, addressing the limitations of existing ring-based schemes. It focuses on improving load balancing and minimizing churn in distributed systems. The key innovation is restricting the Highest Random Weight (HRW) selection to a cache-local window, which allows for efficient key lookups and reduces the impact of node failures. The paper's significance lies in its potential to improve the performance and stability of distributed systems by providing a more efficient and robust consistent hashing algorithm.
Reference

“LRH reduces Max/Avg load from 1.2785 to 1.0947 and achieves 60.05 Mkeys/s, about 6.8x faster than multi-probe consistent hashing with 8 probes (8.80 Mkeys/s) while approaching its balance (Max/Avg 1.0697).”

Accelerating Diffusion Transformers with Fidelity Optimization

Published:Dec 29, 2025 07:36
1 min read
ArXiv

Analysis

This paper addresses the slow inference speed of Diffusion Transformers (DiT) in image and video generation. It introduces a novel fidelity-optimization plugin called CEM (Cumulative Error Minimization) to improve the performance of existing acceleration methods. CEM aims to minimize cumulative errors during the denoising process, leading to improved generation fidelity. The method is model-agnostic, easily integrated, and shows strong generalization across various models and tasks. The results demonstrate significant improvements in generation quality, outperforming original models in some cases.
Reference

“CEM significantly improves generation fidelity of existing acceleration models, and outperforms the original generation performance on FLUX.1-dev, PixArt-$α$, StableDiffusion1.5 and Hunyuan.”

Programmable Photonic Circuits with Feedback for Parallel Computing

Published:Dec 26, 2025 04:14
1 min read
ArXiv

Analysis

This paper introduces a novel photonic integrated circuit (PIC) architecture that addresses the computational limitations of current electronic platforms by leveraging the speed and energy efficiency of light. The key innovation lies in the use of embedded optical feedback loops to enable universal linear unitary transforms, reducing the need for active layers and optical port requirements. This approach allows for compact, scalable, and energy-efficient linear optical computing, particularly for parallel multi-wavelength operations. The experimental validation of in-situ training further strengthens the paper's claims.
