Hybrid V-Cycle Algebraic Multilevel Preconditioners [PDF]
Mathematics of Computation, 1992 The paper describes a new algebraically defined multilevel preconditioner for the finite element matrix arising from the discretization of a second-order selfadjoint elliptic boundary value problem. The construction of the preconditioner is based on a sequence of grids (levels) given by successive refinement and the corresponding hierarchical two-by ...

Advanced Materials Technologies, EarlyView.This study demonstrates an aluminum‐based hybrid photoresist synthesized via molecular layer deposition (MLD) using trimethylaluminum and hydroquinone. The resist achieves sub‐20 nm resolution and virtually infinite silicon etch selectivity, enabling 40 nm‐wide, micrometer‐tall nanostructures.

Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems
Advanced Materials Technologies, EarlyView.Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.

Zone‐Sectored Organic Crystals with Spatially Resolved Exciton Dynamics
Advanced Optical Materials, EarlyView.Novel type of rubrene microcrystals in the orthorhombic phase are grown exhibiting spatial contrast in spectra and dynamics due to differences in unit cell orientation. Distinct zones selectively host redshifted luminescence band at ≈650 nm driven by high photon absorption.

Scalable Task Planning via Large Language Models and Structured World Representations
Advanced Robotics Research, EarlyView.This work efficiently combines graph‐based world representations with the commonsense knowledge in Large Language Models to enhance planning techniques for the large‐scale environments that modern robots will need to face. Planning methods often struggle with computational intractability when solving task‐level problems in large‐scale environments ...

Grounding Large Language Models for Robot Task Planning Using Closed‐Loop State Feedback
Advanced Robotics Research, EarlyView.BrainBody‐Large Language Model (LLM) introduces a hierarchical, feedback‐driven planning framework where two LLMs coordinate high‐level reasoning and low‐level control for robotic tasks. By grounding decisions in real‐time state feedback, it reduces hallucinations and improves task reliability.
