Cauchy's problem for a singular parabolic partial differential equation

open access: yesJournal of Differential Equations, 1970
In recent years analytic function theory has been shown to play a basic role in the investigation of existence and uniqueness theorems for solutions to elliptic partial differential equations ([6], [8], [17]). An approach which has proved particularly fruitful is that of integral operators ([l], [12], [17]), from whose use complete families of ...

Manipulating Liquid‐Liquid Interphase Solute Diffusion for the Construction of Non‐Symmetric Metal‐Quinone Network Nanoarchitectonics and Nano‐Motorization

open access: yesAdvanced Science, EarlyView.
Non‐symmetric metal‐quinone network (MQN) nanoarchitectonics with controllable morphology and size are constructed by manipulating interphase solute diffusion during the nanoprecipitation process. Self‐propelled nanomotors developed from non‐symmetric MQN nanoarchitectonics exhibit chemotactic autonomous motion toward overexpressed H2O2 in tumor ...

Comparison Theorem for Nonlinear Path-Dependent Partial Differential Equations

open access: yesAbstract and Applied Analysis, 2014
We introduce a type of fully nonlinear path-dependent (parabolic) partial differential equation (PDE) in which the path ωt on an interval [0, t] becomes the basic variable in the place of classical variables t,x∈[0,T]×ℝd.

Hybrid Solar Spectral‐Splitting Photovoltaic‐Thermal Hydrogen Production Systems

open access: yesAdvanced Science, EarlyView.
A hybrid solar photovoltaic‐thermal hydrogen system with membrane‐less electrolysis significantly boosts solar‐to‐hydrogen efficiency by co‐using thermal and electrical energy. The system attains good performance under variable irradiance with direct current power converters.

Parabolic Partial Differential Equations as Inverse Moments Problem [PDF]

open access: yesApplied Mathematics, 2016
We considerer parabolic partial differential equations under the conditions on a region . We will see that we can write the equation in partial derivatives as an Fredholm integral equation of first kind and will solve this latter with the techniques of inverse moments problem.

Designing Spin Symmetry for Altermagnetism with Strong Magnetoelectric Coupling

open access: yesAdvanced Science, EarlyView.
Antiferromagnets can be induced into altermagnets by changing the real‐space symmetry, increasing their potential for use in spintronic devices. Here, a novel and general approach is proposed: transforming antiferromagnets into altermagnets by modulating spin‐space symmetry, rather than real‐space symmetry.
