Reduced compression time is not sufficient for stability in patellar buttons

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patellar resurfacing in total knee arthroplasty requires stable cement fixation of the patellar button. Unlike femoral and tibial components, the patellar button is held under manual compression until cement curing, potentially prolonging operative time.

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 ...
