Challenges and Opportunities of Upconversion Nanoparticles for Emerging NIR Optoelectronic Devices

Advanced Materials, EarlyView.
The special photo‐responsiveness of upconversion nanoparticles has opened up a new path for the advancement of near‐infrared (NIR)‐responsive optoelectronics. However, challenges such as low energy‐conversion efficiency and high nonradiative losses still persist.

Temporally Reconfigurable Reservoir Computing with Flexible Electrolyte‐Gated TFTs for High‐Performance Neuromorphic Processing

Advanced Materials, EarlyView.
A temporally reconfigurable reservoir computing system is developed using ultrathin, flexible, all‐solid‐state electrolyte‐gated thin‐film transistors (UFLEX TFTs). By simply tuning temporal dynamics electrically, the system achieves 93.7% accuracy for MNIST handwritten digits, 90.3% for CIFAR‐10 images, and 81.8% for chest X‐rays, surpassing CNNs in ...

Plant structural complexity and mechanical defenses mediate predator-prey interactions in an odonate-bird system. [PDF]

, 2017
Habitat-forming species provide refuges for a variety of associating species; these refuges may mediate interactions between species differently depending on the functional traits of the habitat-forming species.

Machine Learning‐Enhanced Modular Ionic Skin for Broad‐Spectrum Multimodal Discriminability in Bidirectional Human–Robot Interaction

Advanced Materials, EarlyView.
A machine learning‐enhanced modular ionic skin with broad‐spectrum multimodal sensing is realized through a synergistic material–algorithm optimization strategy. This strategy involves hard‐segment‐modulated 1D/2D/3D‐ionic conductors and a data‐driven decoupling model trained on a curated multi‐stimuli dataset.

The Annual Cycle of German Adult Ospreys – Studies in the Breeding and Wintering Areas as Well as During Migration Since 1995 by Means of Satellite Telemetry

Пернатые хищники и их охрана, 2018
German Ospreys (Pandion haliaetus) were thought to migrate to sub-Saharan Africa. However, most of the many ring recoveries were from juvenile birds, and adults had never been satellite-tracked.

Post-fledging Dependent Behaviour, Dispersion and Migration of Young Eastern Imperial Eagles from Slovakia as Revealed by Satellite Telemetry

Пернатые хищники и их охрана, 2018
In 2005, five nestling Imperial Eagles (Aquila heliaca) were fitted with battery-powered GPS Satellite Transmitters (PTTs) in Slovakia to study their behaviour after fledging, two of them in the east and the other three in the west of the country.
