Diversity of Safety Arguments in the Validation of a Sounding Rocket Destruction System [PDF]
, 2001 This work describes an approach for the validation of a software system responsible for the destruction of the sounding rocket VS-40X. The process of validation uses three different techniques ranging from the automatic state exploration to the laborious

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 1, Page 97-107, January 2026.ABSTRACT Conventional hypergolic propellants cause technical problems due to their toxicity and carcinogenic properties, which increase development costs and lead to significant environmental issues. These challenges can be addressed by incorporating additives with low‐toxicity fuels to render them hypergolic.

Pulmonary Circulation, Volume 16, Issue 1, January 2026.ABSTRACT Exercise testing has long been essential for evaluating diagnosis, prognosis, and functional status in pulmonary hypertension (PH). Recent advances have clarified its role in defining reference values and prognostic markers. Nonetheless, substantial knowledge gaps persist regarding the implementation of invasive cardiopulmonary exercise ...
