On fractional order differential equations model for nonlocal epidemics
A fractional order model for nonlocal epidemics is given. Stability of fractional order equations is studied. The results are expected to be relevant to foot-and-mouth disease, SARS and avian flu.

Nonlocal Symmetries for Time-Dependent Order Differential Equations [PDF]
A new type of ordinary differential equation is introduced and discussed, namely, the time-dependent order ordinary differential equations. These equations can be solved via fractional calculus and are mapped into Volterra integral equations of second kind with singular integrable kernel. The solutions of the time-dependent order differential equations

SEMILINEAR NONLOCAL DIFFERENTIAL EQUATIONS WITH DELAY TERMS [PDF]
The goal of this paper is to obtain the regularity and the existence of solutions of a retarded semilinear differential equation with nonlocal condition by applying Schauder's fixed point theorem. We con- struct the fundamental solution, establish the Holder continuity results concerning the fundamental solution of its corresponding retarded linear ...

Nanometer‐resolution mapping of individual quantum emitters in hexagonal boron nitride is achieved, allowing us to identify the 440 nm blue emitter as a substituted vertical carbon dimer. Leveraging this atomic‐level insight, the deterministic creation of isolated single 440 nm blue emitters is demonstrated through localized electron beam irradiation ...

Nonlocal Integro-Differential Equations of the Second Order with Degeneration [PDF]
We study the solvability for boundary value problems to some nonlocal second-order integro–differential equations that degenerate by a selected variable. The possibility of degeneration in the equations under consideration means that the statements of the corresponding boundary value problems have to change depending on the nature of the degeneration ...

Compact, robust, and ultralow‐loss on‐chip photonic devices are essential for densely integrated photonic chips. Here, the underlying radiation mechanism in topological valley edge states is unveiled and a new methodology of interface topology driven bandgap and wavevector engineering is proposed to thoroughly suppress their radiation losses, thereby ...

Granular Hydrogels as Brittle Yield Stress Fluids
This work reports the Kamani‐Donley‐Rogers yield stress fluid model can describe granular hydrogel deformation. The model robustly captures transient rheology and self‐healing behavior for granular gels of varying composition using only six parameters. This framework provides new insight regarding the effect of material parameters on granular yielding ...

Nonlocal Parabolic Integro-differential Equations with Delays
In this paper we consider a parabolic integro-differential equation with delay and a nonlocal boundary condition. We apply the method of semidiscretization in time, also known as the method of lines, to establish the existence and uniqueness of the considered problem.

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.
