Nanophotonics, Volume 15, Issue 7, 13 April 2026.We experimentally achieve an ultraflat, 4.35‐W all‐fiber supercontinuum spanning from 414 to 1860 nm (3‐dB bandwidth). To our knowledge, this represents the broadest octave‐spanning, visible‐to‐NIR, ultraflat SC source ever reported, which also exhibits maximal visible band coverage. ABSTRACT We propose a method for generating ultraflat supercontinuum (

Journal of the Association for Information Science and Technology, Volume 77, Issue 4, Page 624-639, April 2026.Abstract Timely detection of problematic research is essential for safeguarding scientific integrity. To explore whether social media commentary can serve as an early indicator of potentially problematic articles, this study analyzed 3815 tweets referencing 604 retracted articles and 3373 tweets referencing 668 comparable non‐retracted articles.

UK Forecasts of Annual GDP: Their Accuracy and the Information Categories Underlying Their Revisions
Journal of Forecasting, Volume 45, Issue 3, Page 977-996, April 2026.ABSTRACT Policy makers are concerned with the accuracy of GDP forecasts and want to understand the reasons for the revision of forecasts. We study these issues by examining forecasts of annual UK GDP growth by a panel of agents, published monthly by HM Treasury. We focus on two main issues: the developing accuracy of the group‐mean forecast as horizons

The Case of Fleeting Orders and Flickering Quotes
Journal of Futures Markets, Volume 46, Issue 4, Page 629-652, April 2026.ABSTRACT The literature controversially discusses the ambiguous motives and driving forces behind quickly cancelled limit orders (fleeting orders), which are characteristic of high‐frequency markets. In particular, manipulative and dysfunctional characteristics are feared. We analyze top‐of‐book fleeting orders—so‐called flickering quotes—and show with

Risk Times in Mission‐Oriented Systems
Quality and Reliability Engineering International, Volume 42, Issue 3, Page 1380-1398, April 2026.ABSTRACT This article assesses risk times in mission‐oriented systems with high safety standards. We examine critical times under two safety policies. The first requires that the system's reliability function, known the first failure of the components, must exceed a reliability level throughout the mission.
