A comparative study for the pair-creation contact process using series expansions
, 2007 A comparative study between two distinct perturbative series expansions for the pair-creation contact process is presented. In contrast to the ordinary contact process, whose supercritical series expansions provide accurate estimates for its critical ...

Subcritical Butane and Propane Extraction of Oil from Rice Bran
BioResources, 2015 Rice bran oil was extracted using hexane, as well as subcritical butane and propane. The quality of rice bran oils obtained using these three solvents was comparatively studied.

, 2016 We calculate the distribution of the size of the percolating cluster on a tree in the subcritical, critical and supercritical phase. We do this by exploiting a mapping between continuum trees and Brownian excursions, and arrive at a diffusion equation ...

Solubility of Benzo[a]pyrene and Organic Matter of Soil in Subcritical Water
Croatica Chemica Acta, 2015 A dynamic subcritical water extraction method of benzo[a]pyrene from soils is under consideration. The optimum conditions for benzo[a]pyrene extraction from soil are described including the soil treatment by subcritical water at 250 °C and 100 atm for 30

Modelling of two-zone accelerator-driven systems [PDF]
Ядерна фізика та енергетика, 2012 Neutron-physical modelings of two-zone subcritical reactor driven by high-intensity neutron generator are considered. The cascade principle in subcritical reactors, the use of which can hypothetically substantially amplify the neutron flux from the ...

A critical point for bifurcation cascades and featureless turbulence
, 2019 In this Letter we show that a bifurcation cascade and fully sustained turbulence can share the phase space of a fluid flow system, resulting in the presence of competing stable attractors.

Properties of minimizers for L2-subcritical Kirchhoff energy functionals
Advances in Nonlinear AnalysisWe consider the properties of minimizers for the following constraint minimization problem: i(c)≔infu∈S1Ic(u),i\left(c):= \mathop{\inf }\limits_{u\in {S}_{1}}{I}_{c}\left(u), where the L2{L}^{2}-unite sphere S1={u∈H1(RN)∣∫RNV(x)u2dxc˜pp∈0,4Nc\gt ...

Cauchy Problem with Subcritical Nonlinearity
Journal of Mathematical Analysis and Applications, 1997 The authors consider the asymptotic behaviour of solutions of parabolic systems \[ u_t=- Au+f(u_1,\dots,u_d,\dots, \partial^\alpha_iu_j,\dots),\;i\leq n,\;j\leq d,\;(x,t)\in\mathbb{R}^n\times \mathbb{R}_+,\tag{1} \] with \(u(0,x)= u_0(x)\). In (1), \(A\) is a linear matrix operator of uniformly elliptic type of order \(2m\) while the order \(\alpha ...

A Stochastic Approach to Thermal Fluctuations during a First Order Electroweak Phase Transition
, 1995 We investigate the role played by subcritical bubbles at the onset of the electroweak phase transition. Treating the configuration modelling the thermal fluctuations around the homogeneous zero configuration of the Higgs field as a stochastic variable ...

AbstractThe index of subcriticality is used to quantify the degree of “how deep a target system has a margin below the critical state.” There are three main categories of subcriticality measurement techniques: the static method, the kinetic method, and the reactor noise analysis method. This chapter is dedicated to explaining the following methods that
