Development of a Personalized Visualization and Analysis Tool to Improve Clinical Care in Complex Multisystem Diseases With Application to Scleroderma

Arthritis Care &Research, EarlyView.
Objective In complex diseases, it is challenging to assess a patient's disease state, trajectory, treatment exposures, and risk of multiple outcomes simultaneously, efficiently, and at the point of care. Methods We developed an interactive patient‐level data visualization and analysis tool (VAT) that automates illustration of the trajectory of a ...

Investor Sentiment Measures

, 2004
Our paper examines two potential proxies for investor sentiment - the closed end fund discount (CEFD) and consumer confidence (CC). We can validate these proxies against a recently available more direct proxy for investor sentiment from UBS/Gallup. We find that the CEFD has no correlation with the UBS/Gallup survey, while the consumer confidence index ...

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

Advanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Relative investor sentiment

International Review of Economics & Finance
We propose a new investor sentiment index by estimating the differences between moments from realized stock returns and option-implied moments. Validating the Relative Investor Sentiment index, we show that the index is correlated with other proxies, exhibits known patterns of stock market reactions to sentiment shocks, is stronger for hard-to ...

Investors' Climate Sentiment and Financial Markets

SSRN Electronic Journal, 2020
We propose a measure of investors' climate sentiment by performing sentiment analysis on StockTwits posts on climate change and global warming. We find that when investors' climate sentiment is high, emission stocks are relatively overpriced. Moreover, we show that an increase in carbon prices is followed by a decrease in the relative value of emission

Toward Scalable Solutions for Silver‐Based Gas Diffusion Electrode Fabrication for the Electrochemical Conversion of CO2 – A Perspective

Advanced Functional Materials, EarlyView.
In this study, the preparation techniques for silver‐based gas diffusion electrodes used for the electrochemical reduction of carbon dioxide (eCO2R) are systematically reviewed and compared with respect to their scalability. In addition, physics‐based and data‐driven modeling approaches are discussed, and a perspective is given on how modeling can aid ...
