Subcritical Instabilities in Neutral Fluids and Plasmas [PDF]
Fluids, 2018 In neutral fluids and plasmas, the analysis of perturbations often starts with an inventory of linearly unstable modes. Then, the nonlinear steady-state is analyzed or predicted based on these linear modes. A crude analogy would be to base the study of a

CORRELATORS AND DESCENDANTS OF SUBCRITICAL STEIN MANIFOLDS [PDF]
International Journal of Mathematics, 2013 We determine the contact homology algebra of a subcritical Stein-fillable contact manifold whose first Chern class vanishes. We also compute the genus-0 one point correlators and gravitational descendants of compactly supported closed forms on their subcritical Stein fillings.

Systematic Route to Subcritical Dynamo Branches
Physical Review Letters, 2022 We demonstrate that the nonlinear optimisation of a finite-amplitude disturbance over a freely evolving and possibly even turbulent flow, can successfully identify subcritical dynamo branches as well as the structure and amplitude of their critical perturbations.

Subcritical Nuclear Assembly [PDF]
, 2014 A Subcritical Nuclear Assembly is a device where the nuclear-fission chain reaction is initiated and maintained using an external neutron source. It is a valuable educational and research tool where in a safe way many reactor parameters can be measured ...

Study on Neutronics Design of an Accelerator Driven Subcritical Reactor [PDF]
, 2010 Thorium fueled Accelerator Driven Subcritical Reactors have been proposed as a more comprehensive alternative to conventional nuclear reactors for both energy production and for burning radioactive waste.

, 2021 AbstractFor a subcritical reactor system driven by a periodically pulsed spallation neutron source in KUCA, the Feynman-α and the Rossi-α neutron correlation analyses are conducted to determine the prompt neutron decay constant and quantitatively to confirm a non-Poisson character of the neutron source.

Nonexistence of Subcritical Solitary Waves [PDF]
Archive for Rational Mechanics and Analysis, 2021 AbstractWe prove the nonexistence of two-dimensional solitary gravity water waves with subcritical wave speeds and an arbitrary distribution of vorticity. This is a longstanding open problem, and even in the irrotational case there are only partial results relying on sign conditions or smallness assumptions.

Subcritical monotone cellular automata
Random Structures & Algorithms, 2023 AbstractWe study monotone cellular automata (also known as ‐bootstrap percolation) in with random initial configurations. Confirming a conjecture of Balister, Bollobás, Przykucki and Smith, who proved the corresponding result in two dimensions, we show that the critical probability is non‐zero for all subcritical models.
