Online Feature Selection with Group Structure Analysis [PDF]

, 2016
Online selection of dynamic features has attracted intensive interest in recent years. However, existing online feature selection methods evaluate features individually and ignore the underlying structure of feature stream. For instance, in image analysis, features are generated in groups which represent color, texture and other visual information ...

StahlDigital: Ontology‐Based Workflows for the Steel Industry

Advanced Engineering Materials, EarlyView.
The strength of the steel industry is based on the mastery of microstructure–property relationships. Digital workflows contribute to this aim by making the complexity of workflows reproducible and their execution user independent. The tools and workflows developed in the project StahlDigital as part of the German MaterialDigital initiative are ...

Chasing Charge Carriers: Diffusion Dynamics in Mixed‐n Quasi‐2D Colloidal MAPbBr3 Perovskites

Advanced Functional Materials, EarlyView.
Metal halide perovskites are noted for their tunable optical properties. Colloidal synthesis allows the formation of differently shaped perovskite nanocrystals with varying optical and carrier transport behavior. Three MAPbBr3 morphologies are characterized: nanoplatelets, nanosheets, and nanostripes.

Versatile Green Transfer of Magnetoelectronics with Loss‐Free Performance and High Adhesion for Interactive Electronics

Advanced Functional Materials, EarlyView.
An environmentally friendly transfer printing method of nm‐thick giant magnetoresistive (GMR) sensors is demonstrated. This method, relying on water and biocompatible polyvinyl alcohol (PVA) polymer without the need of complex treatments, allows transferring thin films to a wide range of biological, organic, and inorganic substrates.

Building strength for the long haul toward liberation: What psychology can contribute to the resilience of communities targeted by state‐sanctioned violence

American Journal of Community Psychology, Volume 70, Issue 3-4, Page 475-492, December 2022., 2022
Abstract State‐sanctioned violence (SSV) has resounding effects on entire populations, and marginalized communities have long persisted in the work toward liberation despite continued SSV. This paper aims to bridge the gap between the vast scholarship on resilience and the practical challenge of sustaining and thriving in communities targeted by SSV ...

Hybrid Online-Offline Learning for Task Offloading in Mobile Edge Computing Systems [PDF]

IEEE Transactions on Wireless Communications (2023)
We consider a multi-user multi-server mobile edge computing (MEC) system, in which users arrive on a network randomly over time and generate computation tasks, which will be computed either locally on their own computing devices or be offloaded to one of the MEC servers.
