Strong solutions of the Landau-Lifshitz-Bloch equation in Besov space
We focus on the existence and uniqueness of the three-dimensional
Landau-Lifshitz-Bloch equation supplemented with the initial data in Besov
space . Utilizing a new commutator estimate, we
establish the local existence and uniqueness of strong solutions for any
initial data in . When the initial data is small
enough in , we obtain the global existence and
uniqueness. Furthermore, we also establish a blow-up criterion of the solution
to the Landau-Lifshitz-Bloch equation and then we prove the global existence of
strong solutions in Sobolev space under a new condition based on the blow-up
criterion.Comment: 20 page
Weak solutions to the Hall-MHD equations whose singular sets in time have Hausdorff dimension strictly less than 1
In this paper, we focus on the three-dimensional hyper viscous and resistive
Hall-MHD equations on the torus, where the viscous and resistive exponent
with a fixed constant . We prove the
non-uniqueness of a class of weak solutions to the Hall-MHD equations, which
have bounded kinetic energy and are smooth in time outside a set whose
Hausdorff dimension strictly less than 1. The proof is based on the
construction of the non-Leray-Hopf weak solutions via a convex integration
scheme.Comment: 39 page
Global existence of strong solutions to the Landau-Lifshitz-Slonczewski equation
In this paper, we focus on the existence of strong solutions for the Cauchy
problem of the three-dimensional Landau-Lifshitz-Slonczewski equation. We
construct a new combination of Bourgain space and Lebesgue space where linear
and nonlinear estimates can be closed by applying frequency decomposition and
energy methods. Finally, we establish the existence and uniqueness of the
global strong solution provided that the initial data belongs to Besov space

Derivation of the Hall-MHD equations from the Navier-Stokes-Maxwell equations
By using a set of scaling limits, the authors in \cite{ADFL,SS} proposed a
framework of deriving the Hall-MHD equations from the two-fluids Euler-Maxwell
equations for electrons and ions. In this paper, we derive the Hall-MHD
equations from the Navier-Stokes-Maxwell equations with generalized Ohm's law
in a mathematically rigorous way via the spectral analysis and energy methods

In vitro and in vivo antiviral activity of monolaurin against Seneca Valley virus
IntroductionSurveillance of the Seneca Valley virus (SVV) shows a disproportionately higher incidence on Chinese pig farms. Currently, there are no vaccines or drugs to treat SVV infection effectively and effective treatment options are urgently needed.MethodsIn this study, we evaluated the antiviral activity of the following medium-chain fatty acids (MCFAs) or triglycerides (MCTs) against SVV: caprylic acid, caprylic monoglyceride, capric monoglyceride, and monolaurin.ResultsIn vitro experiments showed that monolaurin inhibited viral replication by up to 80%, while in vivo studies showed that monolaurin reduced clinical manifestations, viral load, and organ damage in SVV-infected piglets. Monolaurin significantly reduced the release of inflammatory cytokines and promoted the release of interferon-γ, which enhanced the viral clearance activity of this type of MCFA.DiscussionTherefore, monolaurin is a potentially effective candidate for the treatment of SVV infection in pigs
