Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers

Laser &Photonics Reviews, EarlyView.
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 ...

Time‐Modulated Optomechanics Reveal Energy Flow and Inelastic Interactions Between Acoustic Phonons in Nanomembranes

Laser &Photonics Reviews, EarlyView.
Temporal interfaces are abrupt refractive index changes used in time‐varying optics, but also transitions to nonequilibrium states. This work explores the inelastic scattering of time‐varying light by nonthermal acoustic phonons in the vicinity of temporal interfaces.

Viscoelastic flows with dominating extensions: application to squeezing flows

, 1986
Plane viscoelastic flows with dominating extensions are defined as thin- layer flows described by the constitutive equations valid for steady or unsteady extensions and perturbed with respect to the strain-rate invariants. Certain approximate solutions and applications to continuous squeezing flows are discussed in greater detail.

Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

International Journal of Mechanical System Dynamics, EarlyView.
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 ...

Immunomodulatory, Antibacterial, Antioxidative and EGF‐Delivering Hydrogel Remodels Wound Microenvironment for Infected Diabetic Wound Healing

National Materials, EarlyView.
In this study, we engineered an antibacterial, antioxidative and epidermal grow factor‐encapsulated multifunctional hydrogel for the repair of chronic and refractory wounds. The hydrogel markedly promoted wound healing in rat models of diabetic foot ulcers and infected wounds by modulating wound microenvironment.

New and Emerging Artificial Urinary Sphincters for Male Stress Urinary Incontinence: From Gold Standard to Next Generation

Neurourology and Urodynamics, EarlyView.
ABSTRACT Introduction For more than four decades, the AMS‐800 has remained the clinical benchmark device for the treatment of male stress urinary incontinence (SUI). Although it remains the gold standard for male SUI, the AMS‐800 has continued to have limitations such as suboptimal post‐operative continence rates, fixed hydraulic pressure, need for ...
