How to Achieve High Spatial Resolution in Organic Optobioelectronic Devices?

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores how the optoelectronic properties of organic semiconductors impact on the resolution of light‐activated bioelectronic interfaces. Using photovoltage and photocurrent microscopy techniques, the authors show that H2PC/PTCDI heterojunctions enable a resolution down to 6.5 µm due to low carrier mobility along the heterojunction.

Better Word Embeddings by Disentangling Contextual n-Gram Information [PDF]

open access: yesarXiv, 2019
Pre-trained word vectors are ubiquitous in Natural Language Processing applications. In this paper, we show how training word embeddings jointly with bigram and even trigram embeddings, results in improved unigram embeddings. We claim that training word embeddings along with higher n-gram embeddings helps in the removal of the contextual information ...

High‐Resolution and Surface‐Sensitive Tip‐Enhanced Raman Spectroscopy Characterization of Strained‐Silicon Devices through Cleanroom‐Compatible Plasmonic Probes

open access: yesAdvanced Materials Interfaces, EarlyView.
This paper demonstrates how Tip‐Enhanced Raman Spectroscopy (TERS) can detect diverse levels of strain in a SiGe‐Si structure in less than 20 nm of depth with lateral resolution under 100 nm. The measures are performed with a TiN‐coated probe, which secures a remarkable enhancement of the optical signal, while being chemically stable to allow TERS to ...

Probing for Semantic Classes: Diagnosing the Meaning Content of Word Embeddings [PDF]

open access: yesarXiv, 2019
Word embeddings typically represent different meanings of a word in a single conflated vector. Empirical analysis of embeddings of ambiguous words is currently limited by the small size of manually annotated resources and by the fact that word senses are treated as unrelated individual concepts.

Carbon Dot‐Doped Silica Xerogel Phosphors Excited by Blue LEDs and LDs for the Brilliant White Lighting of Endoscope Tips

open access: yesAdvanced Materials Interfaces, EarlyView.
Carbon dot‐doped silica xerogel phosphors derived by Sol–Gel method exhibit brilliant white light, making them promising candidates for next‐generation endoscopes. The approach offers a sustainable, scalable solution for the development of advanced endoscopic devices with enhanced imaging capabilities and reduced environmental impacts.

Learning Semantic Representations for Novel Words: Leveraging Both Form and Context [PDF]

open access: yesarXiv, 2018
Word embeddings are a key component of high-performing natural language processing (NLP) systems, but it remains a challenge to learn good representations for novel words on the fly, i.e., for words that did not occur in the training data. The general problem setting is that word embeddings are induced on an unlabeled training corpus and then a model ...
