ABSTRACT Sepsis‐induced acute lung injury (ALI) remains challenging to treat, with conventional anti‐inflammatory therapies offering limited efficacy. The lymphatic system is crucial for removing edema and inflammatory mediators, and its impairment can exacerbate lung injury.

Room‐temperature lower‐polariton‐like lasing is realized in an InGaN/GaN thin‐film ridge cavity with lateral distributed Bragg reflectors. Near‐field optical microscopy distinguishes the transverse side‐DBR‐confined mode from a longitudinal photon‐like mode, while simulations reproduce their spatial profiles.

Positive Solutions of a Nonlinear Parabolic Partial Differential Equation
We deal with the existence and uniqueness of positive solutions to a class of nonlinear parabolic partial differential equations, by using some fixed point theorems for mixed monotone operators with perturbation.

Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers
Intensity‐noise dynamics in terahertz quantum cascade lasers are investigated across single‐mode, dense‐comb and harmonic‐comb regimes using graphene thermoelectric detectors. Harmonic combs show ∼10% lower relative intensity noise, while RIN scales as P0−γ$P_0^{ - \gamma }$ with γ≈1.2$\gamma \approx 1.2$, revealing a crossover from spontaneous ...

Plasmon–Exciton Coupling Enhances Second‐Order Nonlinear Response in Borophene–ZnO Hybrid Structures
Nonlinear interactions between plasmons in borophene and excitons in ZnO lead to enhanced nonlinear and incoherent cathodoluminescence, as well as coherent second harmonic generation, under electron‐beam and laser irradiations, respectively. The anisotropic response of borophene, revealed as in‐plane hyperbolic polariton propagation, acts as a control ...

Viscosity solutions of fully nonlinear functional parabolic PDE
By the technique of coupled solutions, the notion of viscosity solutions is extended to fully nonlinear retarded parabolic equations. Such equations involve many models arising from optimal control theory, economy and finance, biology, and so forth.

Emergence of Rashba Spin‐Orbit Coupling in Staggered‐Gyromagnetic Photonic Crystals
Rashba spin‐orbit coupling emerges in a staggered‐gyromagnetic photonic crystal under a uniform out‐of‐plane magnetic bias. The staggered magnetization splits a four‐fold Dirac point into a Rashba band structure carrying helical spin textures, verified by a four‐band k‐p model.

Numerical approximations of difference functional equations and applications [PDF]
We give a theorem on the error estimate of approximate solutions for difference functional equations of the Volterra type. We apply this general result in the investigation of the stability of difference schemes generated by nonlinear first order partial

ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

A Phase‐Field Model for Quasi‐Dynamic Rupture Nucleation and Propagation of In‐Plane Faults
ABSTRACT Computational modeling of faulting processes is an essential tool for understanding earthquake mechanics but remains challenging due to the structural and material complexities of fault zones. The phase‐field method has recently enabled unified modeling of fault propagation and off‐fault damage within a fracture‐mechanics‐based framework ...
