Improved approximation bounds for Vector Bin Packing [PDF]

, 2010
In this paper we propose an improved approximation scheme for the Vector Bin Packing problem (VBP), based on the combination of (near-)optimal solution of the Linear Programming (LP) relaxation and a greedy (modified first-fit) heuristic.

Active Learning‐Accelerated Discovery of Fibrous Hydrogels with Tissue‐Mimetic Viscoelasticity

Advanced Functional Materials, EarlyView.
Active learning accelerates the design of fibrous hydrogels that mimic the viscoelasticity of native tissues. By integrating multi‐objective optimization and closed‐loop experimentation, this approach efficiently identifies optimal formulations from thousands of possibilities and decouples elasticity and viscosity. The resulting hydrogels offer tunable

A multidimensionally consistent version of Hirota's discrete KdV equation

, 2011
A multidimensionally consistent generalisation of Hirota's discrete KdV equation is proposed, it is a quad equation defined by a polynomial that is quadratic in each variable.

Multidimensiones

Cultura de Paz, 2015
Comparto mi nueva pieza, mide y está hecha sobre madera pintada con laca y placa tipográfica reciclada además de latas de aluminio recortadas. Se intitula Multidimensiones, porque la teoría M de la física cuántica explica que hay un montón de dimensiones, ya sea 10 u 11, además de las tres con las que estamos familiarizados, esas dimensiones que no ...

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

Advanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...
