Abstract We derive a priori bounds for the $$\Phi ^4$$ ? 4 equation in full sub-critical regime using Hairer’s theory of regularity structures. The is formally given by "Equation missing"where term $$+\infty \phi $$ <mml...

By use of the Bacillus subtilis bacteriophage cloning vehicle phi 105J23, B. subtilis chromosomal MboI fragments have been cloned that alleviate the pleiotropic effects of the recE4 mutation. The recombinant bacteriophages phi 105Rec phi 1 (3.85-kilobase insert) and phi 105Rec phi 4 (3.3-kilobase insert) both conferred on the recE4 strain YB1015 resistance to ethylmethane sulfonate, methylmetha...

In this study, we will introduce the modified (G'/G2)-expansion method to explore some of exact traveling wave solutions nonlinear partial differential equations namely, Phi-4 equation, Joseph-Egri (TRLW) and Calogro-Degasperis (CD) equation. As a result, have obtained for expressed in terms trigonometric, hyperbolic rational functions. Moreover, selected are plotted using specific values param...

We characterize the post-inflationary dynamics of an inflaton $\phi$ coupled to multiple interacting daughter fields $X_n$ ($n=1,\dots N_d$) through quadratic-quadratic interactions $g_n^ 2\phi^2 X_n^2$. assume a monomial potential $V(\phi) \propto |\phi|^p$ ($p \geq 2$) around minimum. By simulating system in 2+1-dimensional lattices, we study evolution energy distribution and equation state, ...

The current study investigates the dissipation kinetics of two imidacloprid (IMI) nanoformulations (entitled: Nano-IMI and Nano-IMI/TiO2) on common bean (Phaseolus vulgaris) seeds under field conditions and compares them with 35% Suspension Concentrate (SC) commercial formulation. To do so, it sprays P. vulgaris plants at 30 and 60 g/ha within green bean stage, sampling them during the 14-day p...

A thermal diffusion flow probe incorporating a Peltier stack has been found to give a quantitative dynamic assessment of cortical blood flow in both the laboratory and clinical settings. Further calibration characteristics of the probe were evaluated by correlation with the fast component of Xe133 clearance in cats. The correlation has some linear characteristics but is better defined by the eq...

Much of longitudinal data analysis begins with dimensionality reduction, i.e., the replacement of the T observations x1 , x2 , …, xT on an individual taken at times t1 , t2 , …, tT (not necessarily equally spaced) by a smaller number, P, of parameters which are then used to describe and compare growth processes. We focus on the class of polynomial growth curve models for one-sample data matrice...

We study the evolution of energy distribution and equation state Universe from end inflation until onset either radiation domination (RD) or a transient period matter (MD). use both analytical techniques lattice simulations. consider two-field models where inflaton $\Phi$ has monomial potential after $V(\Phi) \propto |\Phi - v|^p$ ($p\geq2$), is coupled to daughter field $X$ through quadratic-q...
