Fluorene‐based blue emitters: On the path to electrically pumped organic lasers

FlexMat, EarlyView.
Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...

Improving Implied Volatility Forecasts for American Options Using Neural Networks

Journal of Futures Markets, EarlyView.
ABSTRACT This paper explores the application of neural networks to improve pricing of American options. Focusing on both American and European options on the S&P 100 index from January 2016 to August 2023, we integrate neural networks to model the difference between market‐implied and model‐implied volatilities derived from the Black‐Scholes and Heston

Pharmaceutical Pricing and R&D as a Global Public Good

Health Economics, EarlyView.
ABSTRACT This paper examines the international variation in the prices of branded pharmaceuticals. We consider short‐run profits, or quasi‐rents, as representing each country's contribution toward the global public good of therapeutic information embodied in new pharmaceuticals.

Ch‐Ch‐Ch‐Ch‐Changes: The Impact of Supply Base Growth, Contraction, and Turnover on Firm Innovation

Journal of Operations Management, EarlyView.
ABSTRACT Modern supply chains are experiencing more disturbances due to regulatory shifts, rising sustainability standards, emerging or declining markets, and disruption to critical inputs. Some firms react by strengthening existing supplier partnerships to resist changes, while others reconfigure relationships with suppliers to embrace changes ...
