Comparative analysis of contextual and context-free embeddings in disaster prediction from Twitter data

open access: yesMachine Learning with Applications, 2022
Twitter is a social media site where people post their personal experiences, opinions, and news. Due to the ubiquitous real-time data availability, many rescue agencies monitor this data regularly to identify disasters, reduce risk, and save lives ...

Bioxolography Using Diphenyliodonium Chloride and N‐Vinylpyrrolidone Enables Rapid High‐Resolution Volumetric 3D Printing of Spatially Encoded Living Matter

open access: yesAdvanced Materials, EarlyView.
Bioxolography, a novel volumetric 3D‐bioprinting technique, enables rapid and high‐resolution fabrication of >1 cm3 engineered living materials. A newly developed three‐component photoinitiator system significantly enhances the photoreactivity of gelatin methacryloyl‐based bioresins, allowing for precise xolographic bioprinting.

Manipulating the Assembly and Architecture of Fibrillar Silk

open access: yesAdvanced Materials, EarlyView.
In this study, advanced in situ AFM, PiFM, and Cryo‐EM are leveraged to realize in situ observations of nucleation, growth, and degradation of silk nanofibrils. A clear picture of the assembly and structural evolution of regenerated silk nanofibrils is defined and demonstrates a novel strategy for manipulating their structure and properties, which ...

Domain Adapted Word Embeddings for Improved Sentiment Classification [PDF]

open access: yesarXiv, 2018
Generic word embeddings are trained on large-scale generic corpora; Domain Specific (DS) word embeddings are trained only on data from a domain of interest. This paper proposes a method to combine the breadth of generic embeddings with the specificity of domain specific embeddings.

Sociolinguistic Properties of Word Embeddings

open access: yes, 2020
This is a preprint for a book chapter published in Dehghani, Morteza, and Ryan L. Boyd, eds. Handbook of Language Analysis in Psychology. Guilford Publications, 2022. In this chapter, we describe the burgeoning empirical evidence showing how meanings captured in word embeddings correspond to human meanings.

Ag‐Cu Nanoarchitecture for Enhanced LSPR Absorption: the Role of Surface Roughness and near‐field Interactions

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates the plasmonic properties and biosensing capabilities of a nanocomposite incorporating Cu and Ag nanoparticles for detecting anti‐DbpA antibodies associated with Lyme disease. The enhanced LSPR response is explained through FDTD simulations of Cu–Ag near‐field interactions and increased surface roughness.

Chitosan‐Graft‐Gelatin Hydrogel Containing Bromothymol Blue as a Food Spoilage Indicator for Intelligent Food Packaging

open access: yesAdvanced Materials Interfaces, EarlyView.
A chitosan‐graft‐gelatin hydrogel, incorporating a pH‐responsive dye, bromothymol blue, as a colorimetric freshness indicator is introduced to monitor the spoilage of chicken breasts. The hydrogel indicates microbial activity, and the production of carbon dioxide due to deteriorating food freshness via a change in pH, and serves as a smart and visual ...

Elastomeric Nanocomposite with Solvent‐Free, One Step, In Situ Shear Exfoliation of Graphite to Graphene

open access: yesAdvanced Materials Interfaces, EarlyView.
This work presents a novel strategy for nanocomposite fabrication that imparts high shear and elongational forces, overcoming the interlayer van der Waals forces within bulk 2D materials and facilitating their exfoliation in elastomers. Additionally, the high shear forces promote effective nanoparticle dispersion and in situ bond formation, leading to ...
