Common Equity Investors’ Assessments of the Dilution and Solvency Effects of Preferred Stock Instruments

open access: yesJournal of Business Finance &Accounting, EarlyView.
ABSTRACT Generally accepted accounting principles (GAAP) requires dichotomous classification of financial claims as liabilities or equity. Classifying claims is challenging when instruments have attributes of both liabilities and equity (i.e., hybrid instruments).

Franco‐British Bilateral Diplomacy After Brexit, 2020–2025: Mending the Ties That Bind

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract Brexit shook to its very core one of the European Union's (EU's) prominent partnerships, the Franco‐British bilateral relationship (FBBR), disrupting diplomatic routines and shattering interpersonal trust before circumstances changed and the relationship rapidly began to mend. In this article, we analyse the breakdown and restoration of Franco‐

Ordered Median Traveling Salesman Problem

open access: yesNetworks, Volume 88, Issue 1, Page 59-84, July 2026.
ABSTRACT This paper introduces a novel combinatorial optimization problem with ordering constraints, termed the Ordered Median Traveling Salesman Problem (OMTSP). The OMTSP integrates key elements from both the classic Traveling Salesman Problem (TSP) and the Ordered Median Location Problem.

Infrared‐Microwave Compatible Stealth Transparent Metasurface With Digital Camouflage and Hybrid Absorption‐Scattering

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
Traditional metasurfaces suffer from the drawbacks of pure microwave absorption and low IR emissivity stealth, namely failing to match complex ambient backgrounds with varying IR emissivity and generating excess heat accumulation (enhanced IR thermal radiation).

Influence of Higher Concentrations of Multiwalled Carbon Nanotubes on the Tensile and Flexural Performance of Glass Fiber Reinforced Polymers

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
The addition of MWCNTs enhanced the tensile and flexural behavior of GFRP composites. Maximum strength and stiffness were obtained at 3 wt% MWCNTs, whereas intermediate contents showed reduced performance due to poor dispersion. The results confirm that uniform nanotube dispersion is essential for achieving reliable mechanical performance in GFRP ...

Degradation Prediction of Proton‐Exchange Membrane Fuel Cell Tested Under Static and Quasi‐Dynamic Operating Conditions

open access: yesFuel Cells, Volume 26, Issue 3, June 2026.
ABSTRACT The viability and extended lifetime of proton‐exchange membrane (PEM) fuel cells are essential to enable hydrogen electric aviation. Their reliability, that is, the ability to maintain stable performance over long operational periods under varying environmental and load conditions, is a critical factor for their adoption in aviation systems ...
