Rigorous numerics for PDEs with indefinite tail: existence of a periodic solution of the Boussinesq equation with time-dependent forcing

, 2015
We consider the Boussinesq PDE perturbed by a time-dependent forcing. Even though there is no smoothing effect for arbitrary smooth initial data, we are able to apply the method of self-consistent bounds to deduce the existence of smooth classical periodic solutions in the vicinity of 0.

Donkwa Enriched With Goron‐Tula (Azanza garckeana) Modulates Sexual Behavior and Activity of Enzymes Linked With Erectile Dysfunction in High‐Fat Diets/ Streptozotocin‐Induced (STZ/HFD) Diabetic Rats

Food Chemistry International, EarlyView.
(A) Mount number, (B) mount latency, (C) intromission number, and (D) intromission latency are the parameters of sexual behavior. Met = metformin. D100 = 100 Donkwa. D90G10 = 90% Donkwa + 10% Goron‐Tula. D85G15 = 85% Donkwa + 15% Goron‐Tula. D80G20 = 80% Donkwa + 20% Goron‐Tula. The mean ± standard error of the mean (SEM) expressed the results. *Values

Subspace Acceleration for Efficient Nonlinear Water Wave Simulation

International Journal for Numerical Methods in Fluids, EarlyView.
We introduce an exponentially weighted subspace acceleration technique to reduce GMRES iterations for solving the Poisson equation with time‐dependent coefficients in nonlinear, dispersive free‐surface flows governed by the incompressible Navier‐Stokes equations. The method significantly reduces memory requirements and computational complexity compared

Clinical Efficacy and Safety of Topical Roflumilast in Psoriasis: An Updated Systematic Review and Meta‐Analysis of Randomized Controlled Trials

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Traditional first‐line topical treatments for plaque psoriasis, particularly corticosteroids and vitamin D analogs, frequently have only limited efficacy for long‐term use, and present difficulties with safety and adherence. Objectives In this systematic review and meta‐analysis of randomized controlled trials (RCTs), we assessed ...

Pressure swing adsorption process modeling using physics-informed machine learning with transfer learning and labeled data

Green Chemical Engineering
Pressure swing adsorption (PSA) modeling remains a challenging task since it exhibits strong dynamic and cyclic behavior. This study presents a systematic physics-informed machine learning method that integrates transfer learning and labeled data to ...

Oscillatory dynamics in a model of vascular tumour growth - implications for chemotherapy

Biology Direct, 2010
Background Investigations of solid tumours suggest that vessel occlusion may occur when increased pressure from the tumour mass is exerted on the vessel walls. Since immature vessels are frequently found in tumours and may be particularly sensitive, such

Effect of HBr on Explosion Limits of Stoichiometric Hydrogen‐oxygen Mixture

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT This work, based on numerical simulations, discusses the effect of HBr as an inhibitor on the explosion limit of stoichiometric hydrogen‐oxygen gas mixture in a closed spherical vessel. The numerical simulation solves the complete governing equations for mass, momentum, species and energy.

From integral manifolds and metrics to potential maps

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2004
Our paper contains two main results: (1) the integral manifolds of a distribution together with two Riemann metrics produce potential maps which are in fact least squares approximations of the starting integral manifolds; (2) the least squares energy ...

PDE admitting Lagrangian solutions with nontrivial homotopy invariants (π-degree, polarization index, maslov period)

Journal of Differential Equations, 1991
The author considers four qualitative invariants for Lagrangian cylinders ([\(\theta\)]-period, \(\pi\)-degree, polarization index and Maslov period) and shows that for specific classes of first and second order periodic differential equations in the plane there exist solution Lagrangian cylinders whose invariants are not trivial.
