Advanced Materials Technologies, EarlyView.Hierarchically microarchitected PLA/S/CNT cathodes are fabricated via scalable fused filament 3D printing as high‐sulfur‐loading hosts for rechargeable lithium–sulfur batteries. The assembled Li–S cells with sulfur loadings up to 17 mg cm−2 deliver an areal capacity of 9.2 mAh cm−2 and retain 96% of their discharge capacity after 100 charge–discharge ...

Edmonds polytopes and a hierarchy of combinatorial problems
Discrete Mathematics, 1973 AbstractLet S be a set of linear inequalities that determine a bounded polyhedron P. The closure of S is the smallest set of inequalities that contain S and is closed under two operations: (i) taking linear combinations of inequalities, (ii) replacing an inequality Σ ajxj ≤ a0, where a1, a2,…, an are integers, by the inequality Σajxj ≤ a with a ≥ [a0].

Self‐Assembled Calcite Architectures for Programmable Information Storage
Advanced Materials Technologies, EarlyView.Programmable biomineralization enables the formation of 3D calcite architectures that encode information through spatially defined refractive‐index modulations. Data are written via laser‐directed mineralization, stored in stable voxelized mineral structures, and retrieved non‐destructively through optical diffraction, offering a pathway toward ultra ...

Lead‐Free Chiral Hybrid Metal Halides for Circularly Polarized Light‐Emitting Diodes
Advanced Optical Materials, EarlyView.Lead‐free chiral hybrid metal halides provide a versatile platform for realizing chiroptical responses through chiral modulation of metal–halide frameworks with diverse dimensionalities, induces inversion‐symmetry breaking and enables dissymmetric excited‐state transitions toward efficient circularly polarized luminescence and electroluminescence. This

On counting problems and the polynomial-time hierarchy
Theoretical Computer Science, 1980 AbstractWe consider the relation between the relativized polynomial time hierarchy and relativizations of Gill's class PP of sets recognizable in polynomial time by probabilistic Turing machines and of Valiant's class D≠P of sets polynomial time Turing reducible to functions that give the number of accepting computations of nondeterministic polynomial ...

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 ...

The quantum criticality of the Standard Model and the hierarchy problem
Journal of High Energy PhysicsThe naturalness principle has long guided efforts to understand physics beyond the Standard Model, with the hierarchy problem as the central issue. We revisit the role of quantum corrections in the fine-tuning of the low-energy effective description and ...
